How Can Liquid Cooling Solutions Bring a New Revolution In Cooling for AI Technology?

The innovative application of artificial intelligence (AI) technology is bringing disruptive changes to various fields and creating new possibilities for operating models and development prospects. The powerful processing power required behind the rapidly growing AI wave also poses new challenges to the cooling requirements of servers.

As the demand for the application of AI technology increases significantly, data centers must process more data at a faster speed, thus driving the transformation of cooling architecture. Traditional air cooling systems (such as fans or refrigerated air conditioners) can no longer cope with the huge heat generated by high-density computing. Liquid-cooled server racks have emerged in recent years and become an innovative solution for this problem.

When the server is performing deep learning and data analysis, the extremely large amount of data and complex processes will generate huge amounts of heat. The liquid cooling system can quickly and effectively remove this heat to ensure that the server can maintain stable operation. The emergence of liquid-cooled server cabinets provides strong support for the development of AI technology; as AI becomes a trending topic this year, "immersion cooling" has attracted widespread attention for its excellent heat dissipation performance, which also means that liquid-cooled server cabinets are leading us to welcome the first year of liquid cooling.

Cooling Challenges For AI Servers in The Face of Increasing Processing Demands

The importance of server cooling for equipment stability

When we use computers or mobile phones, we often feel heat. That is because the central processing unit (CPU) and other electronic parts inside the device generate heat when working. If this waste heat cannot be effectively discharged, it will affect the performance and life of electronic components. In particular, AI servers have stronger processing power and larger storage space than ordinary servers and generate relatively more heat. To ensure that AI servers can continue to provide high computing power, these large-scale AI data centers must use effective heat dissipation architecture to cool down the chips.

Limitations of Traditional Air Cooling Systems: Unable To Handle The Heat of Intensive Workloads

At this stage, the traditional air-cooling system is still the most common cooling method in server racks. It uses air as a heat dissipation medium, blowing cold air into the heat dissipation fins through a fan, performing air circulation, and taking away the heat generated by the server by heat convection. However, the heat dissipation effect of traditional air cooling is limited.

1. Limited heat dissipation capacity
Air is a medium with poor heat conductivity and can only absorb limited heat. Once it reaches saturation, its heat dissipation efficiency will be limited. Especially in high density server racks, where a large number of servers are placed in a limited space, overheating issues are more likely to occur.

2. Noisy
Because the fans need to run at high speeds to circulate enough air to cool the servers, this creates mechanical noise that can cause interference.

3. Low efficiency
If you want enough airflow to cool a large amount of heat, a large space is required. Overall, the efficiency of the traditional air-cooled system is low.

As server processing demands continue to increase, many high-specification servers have approached or exceeded the heat dissipation limit that air-cooling systems can provide. We must use liquid cooling technology to overcome the challenges of low efficiency and increased energy consumption faced by traditional air-cooled heat dissipation architecture.

Advantages of Liquid Cooling Technology and Application of Sealless Magnetic Drive Pump

Compared with traditional air cooling systems, liquid cooling technology can effectively improve heat dissipation efficiency. This is because liquid has better heat conductivity than air and can absorb and take away heat from the server more quickly, ensuring that the equipment will not malfunction due to overheat.

In the past, many data centers used air cooling, but now they use liquid cooling technology as the best solution for heat dissipation in AI servers. Liquid cooling systems usually use fluorinated liquid as the cooling medium, and the sealless magnetic drive pump circulates the coolant in the server racks.

Air Cooling vs. Liquid Cooling

Working principle and advantages of immersion cooling

Immersion cooling technology is an innovative solution that has attracted much attention in the field of data centers and High Performance Computing (HPC) in recent years. The following introduces the operating principle and advantages of immersion cooling applications.

How Does Immersion Cooling Work?

1. Basic Concept:

• Immersion cooling is a type of liquid cooling technology. Immerse servers or electronic equipment directly in non-conductive coolant to directly absorb the heat generated by the chip and take away excess waste heat, thereby optimizing server performance.
• This approach can greatly improve energy efficiency because no other cooling parts such as fans, cooling fins or heat pipes are required.

2. Single-Phase Immersion Cooling:

The server is completely immersed in the cooling tank with coolant, relying on the flow of coolant to conduct the heat energy of the chip and quickly dissipate heat for the chip. After absorbing the heat energy, the coolant whose temperature rises is then transported to the external cooling tower through the heat exchanger and then cooled down. The final coolant is transported back to the cooling tank through the pump and continues to circulate.

3. Two-Phase Immersion Cooling:

Immerse high-temperature electronic components that need to be dissipated in a cooling tank. The heat from the chips will be transferred to the coolant. As the coolant absorbs the heat, it undergoes a phase change to vapor. The vapor rises and condenses into liquid upon contacting the condenser, dripping back into the cooling bath and continuing the heat dissipation cycle. This design can more effectively reduce server temperature and improve heat dissipation efficiency. It not only relies on the flow of coolant but also uses the vaporization of the coolant to take away more waste heat.

Sealless Magnetic Drive Pump Used In Immersion Cooling Technology

In immersion cooling technology, the application of sealless magnetic drive pumps is crucial. In order to maintain efficient and stable operation of the system, the performance of the coolant circulation pump must reach high standards. Sealless magnetic drive pumps are driven by magnetic force, eliminating the need for traditional mechanical seals, eliminating the risk of liquid leakage, and improving system reliability and safety.

Learn about the efficient use of sealless magnetic drive pumps in immersion cooling systems:

1. Coolant circulation: In single-phase immersion cooling and two-phase immersion cooling systems, pumps are used to transport coolant.

• In the single-phase immersion cooling system, the external cooling tower needs to return the coolant to the cooling tank after cooling. This process requires the use of a reliable sealless magnetic drive pump for transportation to ensure the circulation of the system.
• In the two-phase immersion cooling system, after the steam condenses into liquid, part of the liquid drips directly back into the cooling tank, while the rest is driven by a pump to continuously circulate the coolant throughout the system. This ensures effective heat dissipation, maintains uniform coolant distribution, and prevents localized overheating.

2. Enhanced system stability: Since the sealless magnetic drive pump does not have a mechanical shaft, downtime and maintenance costs are reduced, thereby improving the stability and operating efficiency of the entire cooling system.

PTCXPUMP sealless magnetic drive pumps provide various specifications of heads and flow to meet the unique liquid cooling needs of different data centers.

What industries is immersion cooling suitable for?

• Big Data
  In a big data processing environment, servers need to process huge amounts of data, and a large amount of heat will be generated in the process. Immersion cooling technology can effectively absorb and dissipate this heat, ensuring that the system can perform analysis and processing smoothly.
• Artificial Intelligence (AI)
  The operation and training of artificial intelligence require powerful computing power, so efficient cooling systems must be used to take away the heat generated by the servers. Immersion cooling technology can realize “Green Computing”, reduce energy consumption while improving heat dissipation efficiency, help you save operating costs, and keep AI servers stable during high-density computing.
• Edge Computing
  Edge computing requires a rapid and immediate response. In order to avoid delays in data transmission, edge computing and cloud computing have very high requirements for the immediacy and stability of data processing. Computing centers must use appropriate cooling equipment, and immersion cooling technology can quickly remove heat in a limited space and prevent heat accumulation, thereby improving computing efficiency and reducing latency.
• Blockchain & Cryptocurrency
  Blockchain technology and cryptocurrency mining require a large amount of computing resources. Computer equipment using immersion cooling technology can meet the high-performance computing and low-latency requirements of mining programs.

The Future of Liquid Cooling Technology

The rapid development of liquid cooling technology not only promotes the advancement of AI applications but also plays an important role in energy conservation and carbon reduction in global data centers. Immersion cooling systems are gradually becoming the new favorite of data centers with their high-efficiency cooling capabilities and superior energy efficiency.

Future development directions include further improving the efficiency and reliability of the cooling system, how to reduce construction costs, and promoting the application of liquid cooling technology in more emerging fields.

When you purchase a new fluid equipment, the manufacturer needs the user to provide a series of operating conditions. For example, when purchasing chemical pumps, you need to provide basic operating conditions such as head and capacity. Probably this is the common experience of lots of people, and it may make people feel a little troublesome, but because chemical pumps are specially designed for the special needs of the chemical industry, most of the chemicals are dangerous, so compared with the water pumps, there are of course more factors to consider before deciding on an appropriate chemical pump. There are mainly 10 things, which are items that manufacturers must confirm with customers first.

What Should Be Pumped?

First, must know what the chemical fluid to be transferred is. Since the characteristics of chemical fluids will directly affect the type and material of chemical pumps used, understanding the characteristics of chemical fluids is the most preliminary task for pump selection. The fluid properties include corrosiveness, temperature, viscosity, concentration, specific gravity and impurities.
For the relevant technical terms of the pump, there is a detailed explanation in this article: What are the considerations when choosing a pump? It can be read to understand more about this.

What Is the Amount of Fluid Will Be Pumped?

The capacity refers to the volume of fluid that the pump needs to deliver per unit time and indicates the flow rate and amount of the fluid passing through the pump during delivery. It is usually denoted by the letter Q, the unit of measurement is: LPM, m³/h or m³/s. The amount of flow will affect the size of the pump and the diameter of the piping.

How Much Is the Working Pressure?

Working pressure is the force required to move fluid through the system. If the range of working pressure is too high or too low, the expected delivery effect cannot be achieved. Therefore, it is necessary to consider whether to use a chemical pump with good pressure resistance to meet the operating range of the system.

How High Is the Maximum Head?

The height to which the fluid needs to be moved, which means the vertical height from the fluid source surface to the final outlet, in m. The density of the transported liquid, the diameter of the impeller and the number of stages of the impeller will all affect the height of the head.

What Is the Connection Type?

Regarding how to connect and fix the pump and the pipeline, flanges, unions or hoses are usually used. In the application of medium and large pumps, the flange form is often used as the main connection method. Different types of chemical pumps are also equipped with flange types of different specifications.
To get more information of flange, please refer to the following three articles about flange.
Article1: What is a Flange? What are the types of flanges?
Article2: 5 Types Commonly Used Flange Faces
Article3: Flange Standards (ANSI, JIS, DIN, GB)

What Is the Connected Motor Type?

Generally speaking, most pumps need to be connected with a motor and a power as the source of power for the pump (except for specific types of pumps, such as air-operated diaphragm pumps, etc.). When using it with a motor, you need to pay attention to whether there will be failures such as motor burnout. Depending on the application and working environment, the type and specification of the motor are also different.
More about motors: What are the considerations for motor selection?
What's the Difference between Normal Motors, Inverter Duty Motors, and Explosion-Proof Motors?

What Area Are Chemical Pumps Used In?

When chemical pumps are used in the semiconductor industry, PCB industry, medicine and food industry, etc., when cleanliness is in high demand, it is necessary to use pumps made of specific materials, such as stainless steel SUS316L; or in other special environmental conditions, such as using pumps located in coastal areas are prone to corrosion due to the extremely high salinity of seawater. Both pumps and motors require special coatings to prevent erosion by seawater or rain.
For applications such as chemical industry, semiconductor industry, wastewater treatment, energy and environmental protection, petrochemical industry, food industry, pharmaceutical industry, etc., PTCXPUMP is a reliable partner of domestic and foreign manufacturers, and can provide customized and safe magnetic drive pumps according to the operating environment.

How Often Will the Pump Be Operating?

Pumps that run continuously for long periods of time must be constructed of stronger materials to increase durability and extend their service life than pumps that are run only once in a while. When the pump is running without any fluid, it must also be ensured that dry running will not happen, otherwise the motor may burn out very quickly.

How to Protect the Pump?

To prevent pump failure, causing downtime and increasing operating costs, the pump is best used with a dry running protector. The dry running protector is used to monitor the current or power of the motor during operation. When the current is too high or too low, it will immediately issue an alarm or automatically shut down the motor. This function greatly reduces the probability of pump failure and maintenance costs. Based on safety and cost considerations, the optional dry running protector is also a machine that cannot be missed.

Should Maintenance Work be Carried Out by Myself?

To ensure the longevity and efficiency of chemical pumps, proper maintenance and care is essential. Although self-maintenance can save a little cost, entrusting it to a manufacturer with good service, the maintenance of its professionals can guarantee the maintenance of product quality and operational efficiency.

Contact us and provide your requirements, we will assist you in accurate selection and providing the most appropriate pump. The maintenance problems after the products are used can also be entrusted to us with peace of mind. PTCXPUMP has a warehouse and repair factory, and can help you solve any product problems with instant and perfect after-sales service.

The average annual maintenance and operating costs of the pump are higher than other types of rotating machinery. As the main force of the factory, its energy consumption accounts for one of the highest proportions among many industrial equipment. Especially in the chemical industry, because it relies on chemical pumps to transport some corrosive liquids, the time and expense spent on operation and maintenance cannot be underestimated during the entire life cycle of the chemical pumps. Therefore, how to reduce the damage rate of the chemical pump and increase its production capacity has become a common topic for all factories.

Of course, it is well-known to try our best to achieve "energy saving." However, in addition to saving energy consumption of chemical pumps, if we want to have a great effect in reducing costs and increasing factory output, we must also improve the "reliability" of pumps. In order to make the chemical pump run more smoothly, the following methods can be adopted. To save pump energy, these are the ways: 10 Tips on Energy Saving in Pumping Systems

Proper Design and Equipment

Using the proper pump is the first step in building a reliable pumping system. The specifications should meet the operation requirements. Many factors must be taken into consideration, such as flow rate, head, fluid characteristics, operating temperature and pressure, etc., and then accurately select the most suitable model according to the pump performance curve, even under dynamic operating conditions. It can also prevent the chemical pump or parts from overloading and excessive vibration to shorten the service life. How to read the Performance Curve: Easy Way to Understand the Pump Performance Curve

In addition, fatigue wear and cracked surfaces of components are the root causes of pump failures. The fatigue life of components under cyclic or dynamic loading can be programmed to be infinite. For those components that have previously broken, the design can be redeveloped to increase the expected fatigue life as the cyclic loading and associated stresses are reduced.

Operational Status Monitoring

As we often mentioned, the pump needs regular health checks, but in order to grasp its performance in a more timely and comprehensive manner, preventive maintenance must be done, and professional status monitoring tools. The purpose of continuous monitoring is to prevent failures such as process delays or downtime, and expensive repair costs.

Prevent Leakage Problem

If a chemical pump leaks when delivering fluid, it will be a hazard to the operator and the environment, and you will also have to bear the cost of cleanup and material loss. The sealless magnetic drive pump completely seals the fluid in the chamber, which can successfully avoid leakage concerns. The simple structure makes maintenance more convenient and the maintenance frequency can be reduced. In addition, its excellent corrosive fluid handling ability can help your factory to improve productivity. In terms of fluid delivery, the sealless magnetic drive pump can provide a reliable solution.

Pump Packages and Transport

The size of the wooden box for packing the pump must match the size of the product. For different pumps, the transport boxes are different. Try to avoid

damage to the pump and parts during the process of moving and transporting. If you consider environmental protection and operation, you can also replace disposable materials with reusable materials

If you want to build a reliable chemical pump system, please refer to the above four methods to improve pump performance and reliability, but it is also recommended to consult professionals in advance to achieve the desired results.

At PTCXPUMP, we offer reliable sealless magnetic drive pumps. Contact us and a professional team will work with you to help you choose the best chemical pump and increase pump capacity according to actual operating conditions!

Bearings are fixed parts required for mechanical operation, which can keep the shaft at the center and guide the gearing of other parts.

Bearings have a limited service life, and improper use or other factors will accelerate bearing damage, so regular replacement and maintenance are indispensable. If you don’t want to worry about this anymore, you can use the following 7 ways to effectively reduce the risk of damage to mechanical equipment and prolong bearing life.

1. Proper Lubrication
   

   Regular replenishment or replacement of correct, high-quality lubricants, keeping the bearings lubricated is primary, and the oil film surface can minimize the wear of the parts when they are in contact. For equipment operating at high speed, the lubricant can also take away the heat generated by the internal friction of the bearing to achieve the effect of heat dissipation and cooling. The lubricant can use oil or grease, try to choose the lubricant recommended by the original equipment manufacturer (OEM).

   Of course, the lubricant also has a fixed lifespan. When the lubricant loses a certain viscosity and lubricity, it will cause churning, or the bearing will stop suddenly and cause system shutdown. Therefore, it is also necessary to pay attention to the replenishment of lubricant.
   
   

2. Mount the Bearings Correctly
   

   Since the correctness of the bearing installation directly affects the life and mechanical precision, so the correct method and special tools should be used in the process of mounting and dismounting the bearing.

   After installation, it is also necessary to check the installation position, whether the radial clearance of the bearing is just right to rotate flexibly without vibration, whether the lubricant can flow into the bearing smoothly, and confirm whether there is light leakage around the bearing and the shoulder. If there is no light leakage, it means the installation is correct; if there is light leakage around the shoulder, it means that the installation is incorrect, and the bearing needs to be adjusted to make the two close.
   
   

3. Prevent Pollution

   Clean bearings: Bearings are precision components and should be stored horizontally in a clean, dry environment to avoid exposure to any air pollutants. Even the slightest contamination can impair performance, so keep the packaging intact and airtight until ready to use.
   Clean lubricant: In addition, under long-term use, the lubricant will also contain pollutants. In order to prevent the bearing from being worn by particles, the only way to keep it clean is to replace it with new lubricant.

4. Appropriate Seal Type

   The bearing needs to have good sealing performance. If the sealing is not good, dust particles, liquid and other pollutants will enter the bearing, resulting in wear of parts, and due to the leakage of lubricant, it will seriously cause product and environmental pollution. Choose a suitable seal type can help preventing these problems.
   Whether it is temperature or lubricant, there are many factors that affect the sealing type of the bearing, mainly divided into contact seals, non-contact seals, and labyrinth seals.

   
   
   • Contact seals: Also known as the lip seal, pressure is exerted on the inner ring of the bearing so that the seal and the bearing come into contact. Since it is in the form of direct contact, there is no gap between the seal and the rotating shaft, and it is easy to generate heat due to friction during rotation, so it is only suitable for medium and low speed operating environments.
   • Non-contact seals: The seal is fixed on the outer ring and will not exert pressure on the bearing of the inner ring. There is no contact between the seal and the bearing parts. There is a gap between the seal and the rotating shaft, so there is no friction and wear problem under normal operating conditions, and it can also prevent overheating.
   • Labyrinth seals: A more complex labyrinth seal is a bearing isolator that combines contacting and non-contacting sealing elements in one assembly. A labyrinth seal consists of a stationary and rotating part that interlocks the two, and its structure creates small tortuous gaps that make it difficult for substances to escape or penetrate the bearing. Labyrinth seals combine the advantages of contact and non-contact seals, providing the sealing capabilities of contact seals without the frictional overheating problems like non-contact seals.

   However, you get what you pay for, and the price of labyrinth seals with high complexity is of course higher than other seals. Therefore, the most suitable seal type must be evaluated according to the equipment and operating environment.

5. Adjust Load and Bearing Size

   If the bearings do not match the load requirements, wear problems will still occur during high-speed operation, which can be solved by changing the total load of the system or using suitable bearings.

6. Prevents Rust and Corrosion

   Exposure to water for a long time will cause rust and corrosion, and may even fall off during operation, and affect the performance of the mechanical system, so special attention should be paid to dry storage, and gloves must be worn when handling to avoid contact with sweaty hands.
   
   

   

7. Inspection and Maintenance

   Finally, be sure to take regular maintenance and inspections, such as checking the degree of wear, cleaning the bearings with cleaning oil (gasoline, kerosene), etc., so as to ensure the best performance of the bearings and prevent any abnormal conditions of parts or equipment. This is one of the most basic ways to extend bearing life.

However, an ounce of prevention is worth a pound of cure, and here comes an easier and more cost-effective way to solve the above bearing problems!

PTCXPUMP Sealless Magnetic Drive Pump that Can Be Safely Applied

In the use of the pump, in order to reduce the frequency of replacing parts as much as possible, it is recommended to use the PTCXPUMP sealless magnetic drive pump. Compared with the traditional mechanical seal pump, the sealless design can effectively avoid leakage, and there will be no fluid leakage or work safety problems. This aspect is also helpful for improving efficiency.

The bearing part is made of SiC (silicon carbide) material, which has excellent corrosion resistance and high wear resistance. The patented design of the internal flow channel of the bearing allows the fluid to pass through the interior quickly, which not only has the function of instant lubrication, but also can quickly take away the mechanical heat generated by the operation. Since the chemical fluid is not easy to remain, the problem of the pollutants mentioned above is reduced, and there is no need to replace the bearing frequently like ordinary bearings, and at the same time, the possibility of the shaft being stuck due to fluid crystallization is greatly reduced.

In addition, it is made of engineering plastic or metal, which has excellent corrosion resistance and is suitable for transporting highly corrosive liquid such as hydrochloric acid, sulfuric acid, hydrofluoric acid and acetic acid or flammable and explosive fluids.

PTCXPUMP sealless magnetic drive pump has various models to meet your various operating requirements.

Contact us and our professional team will work with you. According to the actual operating conditions, to select the best pump for you. By choosing the correct type of pump to extend the pump service life, so as to reduce production costs.

When we use the pump, in order to maintain its performance and avoid operational problems, there are some maintenance and methods of routine job that need to be understood. The following will introduce how to maintain and inspect the pump to extend the service life of the pump, in order to reduce maintenance costs.

According to the difference in initiative, the types of maintenance are mainly divided into corrective maintenance and preventive maintenance.

What is Corrective Maintenance?

Corrective maintenance: When the pump leaks, the efficiency decreases, stops or the motor failure, resulting in production loss, it is necessary to quickly purchase or install spare parts in an emergency to restore the equipment system to an operational condition.

What is Preventive Maintenance?

Preventive maintenance: Routine or regular (hourly, daily, weekly, monthly, yearly) scheduled inspections aimed at maintaining the equipment in its current state and preventing malfunction, by dismantling devices, replacing seals such as gaskets or mechanical seals, and checking the pump's external and internal parts for wear.

In addition to the necessary to ensure that the pump can operate normally after started through some inspection steps, carrying out the routine preventive maintenance through the following checklists is also a point of pump protection.

Routine inspection:

1. Check the pump body, connection plate and base plate are corroded or damaged.
2. Check whether there is leakage between the pump and the piping.
3. Whether the surface of the motor is damaged or corroded.
4. Whether the pump is operating normally, and check there is any abnormal noise or vibration.
5. Confirm the flow and pressure at the pump inlet.
6. Confirm the flow and pressure at the pump outlet.
7. Confirm the liquid height in the tank.
8. Whether the motor current value is within the rated range.

If there are spare parts, it is also necessary to test run frequently and check whether they can work normally.

Regular inspection:

(depending on the usage conditions and hours, about once every 3 to 6 months)

1. Front casing, rear casing
Check for cracks, abnormal wear, crystallization, or foreign matter attached.

2. Gasket
Check for deformation, corrosion, or swelling.

3. Impeller and inner magnet
Check for scratches or cracks, crack or crystallization on bearings, bearing wear or tear, deformation of the impeller, etc.

4. Shaft
Check for scratches or cracks.

5. Rear casing
Check for corrosion, cracks, holes and scratches.

In addition to the above-mentioned maintenance and detection methods, preventive maintenance also includes the use of monitoring technology to determine the current operating status of system equipment. In order to correct the pump problem before it occurs, the current or power of the pump motor can be monitored by using PTCXPUMP dry run protector. When the current is too high or too low, an immediate warning or automatic shutdown will be issued, which greatly reduces the pump failure probability and maintenance costs.

Considering preventive maintenance, PTCXPUMP sealless magnetic drive pump can reduce the cost of preventive and corrective maintenance because of its simple structure and high durability.

Speaking of flanges, in addition to connecting or closing the pipes, when installing pumps, flange is significant for connected with pipe. After understanding the basic types of flanges and flange faces, the flange standard specification, its resistance pressure capacity, the flange thickness, and applicable countries, also need to be paid attention when selecting.

What are the standards of flanges?
The common flange standards are ANSI, DIN, JIS, GB.
ANSI is most commonly specified in the United States.

The above are the basic flange standards. When considering the flange to be installed with the pump, it is recommended to consult with professionals before selecting.

PTCXPUMP sealless magnetic drive pump provides standard flange specifications(ANSI,JIS,DIN) for easy pipeline connection. It can adjust screw hole position to avoid leakage of inlet and outlet.

Flanges play an important role in connecting pipes, besides knowing the basic types of flanges, it is necessary to further understand the form and application of flange faces. In addition, since the specifications of flanges are very diverse, the standard classification of flanges also needs to be paid attention to when selecting them. The common flange standards will be introduced in the next article.

What are the commonly used flange faces?

1. Flat Face (FF): The smooth surface and simple structure make it easy to process the corrosion-resistant lining. Using full-face gasket to cover the entire flange sealing surface. Due to the large contact area between the sealing surface and the gasket, after pre-tightening, the gasket is easily moved to both sides and be squeezed out of the sealing surface. It is well suited to low pressure and low temperature applications. Flange gaskets are generally divided into metal gaskets and non-metal gaskets, flat face flanges use non-asbestos gaskets.

2. Raised Face (RF): The smooth surface and simple structure make it easy to process. Because of its easy installation, it is the most widely used type of flange employed in the oil and gas and chemical engineering industries. The contact surface of the gasket protrudes from the bolting circle face, concentrating the pressure on a smaller gasket area, thereby increasing the pressure containment capability. Applicable gasket materials include non-metallic flat-ring gaskets and metallic spiral wound gaskets and metal jacketed gaskets.

3. Ring Type Joint (RTJ): The metal ring is placed in the groove, and the gasket will not be pressed into the groove. The compression area is small, and the pressure of the gasket is uniform. When the bolt is tightened, the metal ring is compressed to form a tight seal. Because the gasket and the medium are not in direct contact, it can be used in applications with strict sealing requirements, such as high temperature and high pressure, flammable, explosive and toxic media. Ring type joint flanges use oval ring gaskets or octagonal ring gaskets.


4. Male and Female (MFM): It consists of a male face and a female face, which are used in pairs and are easy to align during installation. Placing the gasket on the female face can prevent the gasket from being extruded, so it can be used in applications with high pressure and strict sealing requirements, but it is not easy to replace the gasket. However, the gasket may still be squeezed out when the male and female flanges are used under high temperature operating conditions. Applicable gasket materials include non-metallic flat gaskets, metallic spiral wound gaskets and metal jacketed gaskets.


5. Tongue and Groove (TG): It consists of a tongue flange and a groove flange, which are used in pairs. The tongue flange is manufactured with a raised ring that is machined into its face, and the groove flange is produced with a matching depression machined onto its face. Placing the gasket in the groove flange, so the compression area is small, the gasket is uniformly stressed, and it is not easy to be extruded. Because the gasket is not in direct contact with the medium, the sealing effect is good, and it can be used in high pressure, flammable, explosive and toxic media, etc. Tongue and Groove flanges use metal and non-metallic flat gaskets, metallic spiral wound gaskets and metal jacketed gaskets.

The above is the basic description of the flange faces. When choosing the flange installed with the pump, it is recommended to consult with professionals before   select it.

When the pump is connected to the pipeline, we generally use flanges, unions or hoses for connection. For the application of medium and large pumps, we often use flanges as the main connection method. Flange refers to the disc-shaped parts used to connect pipes, containers, or fix the shafts. Usually, there are screws and threaded structures to fix them. Flanges are generally used in pairs, the most common in pipeline engineering. The typical connection consist of flanges, gaskets and screws. Gaskets are added to the two flanges and tightly fixed with screws. Widely used in chemical industry, petrochemical industry, firefighting, drainage or water treatment application for liquid transfer solution.

There are countless types of flanges. The commonly used materials are carbon steel, stainless steel, alloy steel, etc. In addition, the thickness, the number of screw holes, and the diameter of the flange need to be selected according to the operation requirements.

The common types of flanges can be divided into Slip On Flange(SO), Weld Neck Flange(WN), Threaded Flange(THDF), Lap Joint Flange(LJ), Socket Weld flange(SW), Blind Flange(BL), and other special types(Specialty Flange), the following basically introduces several main flange types.

Slip On Flange(SO)

A fairly common type with lower installation costs and lower requirements for precise pipe cutting. The steel pipe, pipe fittings are inserted into the inner hole of flange and connected to the pipe through a fillet weld at the flange top and bottom. Since the flange hole is larger than the pipe diameter, it usually requires more welding action than other flanges, so it can effectively prevent leakage. Compared with weld neck flange, it is only suitable for low and medium pressure applications due to the lower neck height.

Weld Neck Flange(WN)

It is a flange that is butt welded to the pipe or fitting, and its installation cost is higher. In contrast to the slip on flange, the distance between the welding joint and the joint surface is large, and the joint surface will not be deformed by the welding temperature. Weld neck flanges are not easily deformed and have high sealing properties, making them suitable for high temperature and high pressure, even for pipelines that transport flammable and toxic fluids.

Threaded Flange(THDF)

The inner hole of the flange is processed into a screw thread and connected with a threaded pipe, which belongs to a non-welded flange. The main feature is easy installation, disassembly and maintenance. However, considering the characteristics of thread structure, it is strongly influenced by the environment, and the temperature in the threaded pipe fluctuates greatly, so it is not suitable for high temperature and high pressure applications.

Lap Joint Flange(LJ)

It consists of two parts, the Stub End and the Backing Flange. The flange is placed on the stub end, and the stub end is butt welded to the pipe joint. The flange can move on the pipe joint. It is mainly used for pipe systems that need to be disassembled frequently for inspection and maintenance. The flanging of the stub end is the sealing surface, and the flange is used to clamp the end of the pipe and the stub end. Because flanging stub end can isolate the flange from medium, it is suitable for conveying corrosive fluids.

Socket Weld flange(SW)

The inner hole of flanges has a socket and is connected by inserting the pipe into the socket and fillet welding around the top. Usually used in smaller, high-pressure pipelines, but not for highly corrosive fluids.

Blind Flange(BL)

It is a flange without a hole in the middle for closing the end of the pipe, with mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface. The function is the same as the head and the cap, and the blind flange is fixed with screws for easy disassembly.

Why do you need to use explosion-proof motors? Explosion-proof motors are mainly used in harsh environments. In the process environment, the air will contain flammable substances, including gas or dust. When a specific concentration is reached, once there is an ignition source, it will cause fire or explosion. Explosion-proof motors can prevent explosions by isolating thermal energy from contact with combustibles and controlling the operating temperature of the motor. When the commonly used sealless magnetic drive pump or centrifugal pump is equipped with an explosion-proof motor, we can call it explosion-proof magnetic pump or explosion-proof centrifugal pump. The explosion-proof motor is selected according to the environment and process. The following will introduce the markings and classifications of explosion-proof equipments.

Explosion-proof marking refers to the mark used to describe the explosion-proof grade, temperature group, protection type and applicable environment of ​​explosion-proof electrical equipment.

The common explosion-proof classification standards mainly include IECEx and ATEX, as well as NEC and CEC.

IECEx: An international, worldwide explosion-proof standard defined by the International Electrotechnical Commission (IEC). An international certification system helps reduce testing and certification costs for manufacturers, allowing the unified standards to be applied in different countries. IECEx is also stricter than ATEX in the certification process.

ATEX: Basically similar to IECEx, but only used in European countries.

NEC: For use in the United States only.

CEC: For use in Canada only.

The following describes the meaning of each indication of the two major standards, IECEx and ATEX.

IECEx ex. 

ATEX ex.

Whether it is temperature, gas or dust, the environment where the equipment is located, etc., there are many factors that determine the specifications of the motor. After the above introduction, when selecting an explosion-proof motor, the meaning of these specifications can be more clearly understood.

Motor is an indispensable part of the industrial automation and one of the most common electrical equipment in life. It is widely used in various electrical appliances, ranging from washing machines and fans in daily life; For industrial applications, pumping, machinery industry and fluid transfer, etc. Motors are also indispensable when pumps are used. Therefore, it is very important to understand and choose a suitable motor. The following describes the differences between normal motors, inverter duty motors and explosion-proof motors.

Normal Motors

There are many types of motors, according to the type of input power, they can be divided into DC motors, AC motors, etc. DC motors can be further subdivided into brushed DC motor, brushless DC motor(BLDC motor); AC motor includes induction motor and synchronous motor. In brief, DC motor controls the rotational speed through voltage, which is easy to control, but not suitable for high temperature and flammable operating environments. The AC motor controls the rotational speed through the frequency of the alternating current, so compared with the DC motor, it is not easy to control the speed, while it can be used in a high temperature and flammable operating environments.

Inverter Duty Motors

A variable frequency drive (VFD) (a.k.a Inverter) is used to change the frequency of the alternating current, by changing and controlling the speed and torque of the AC motor. Therefore, "variable frequency" refers to the way of driving the AC motor. It can be started and adjusted frequently without maintaining full-speed operation and maximum power. When the motor speed is reduced, the output horsepower will also decrease, thereby achieving high efficiency and energy saving. The system control is also more stable than the normal traditional motor.

Explosion-Proof Motors

Mainly used in operating environments where flammable substances exist, such as coal mining, natural gas industry, petrochemical and chemical industries, etc. With the hard explosion-proof shell, it can sustain the explosion pressure inside the motor, and also can isolate the heat from the inflammable materials, so as to avoid the danger of fire or explosion.

According to the explosion-proof form, it can be roughly divided into flameproof motor (symbol d), intrinsic safety motor (symbol i), increased safety motor (symbol e), positive pressure explosion-proof motor (symbol p), non-sparking motor (symbol n), and dust ignition proof motor, etc., depending on the protection level, each has its features and functions.

With a brief understanding of the differences between these motors, I believe it becomes easier to choose the right motor for your needs.


Best Solution For Chemical Transfer – PTCXPUMP Sealless Magnetic Drive Pump

The pump is a general rotating machine, and its operating power comes from the motor. The types of pumps include sealless magnetic drive pumps, mechanical seal pumps or other forms of centrifugal pumps, all of which must be connected to a motor to deliver the fluid.

Motors can be divided into general motors, inverter duty motors and explosion-proof motors. The specifications of the motors are also different according to the application and environment. The following describes how to select a suitable motor according to the requirements when using a pump.

For different purposes, it can be based on motor specifications, such as the number of poles (Pole), RPM, the frequency (Hz), voltage (V), the install location, IP Rating, and the energy efficiency index to decide which model to choose.

Pole, RPM, Frequency (Hz)

Pole represents the number of magnet poles in the stator magnetic field of the motor. According to the different connection forms of the stator coil windings, different numbers of poles in the stator magnetic field can be generated. The number of poles affects the rotational speed of the motor.

RPM stands for revolutions per minute. For example, the rotational speed of the motor is 3,600RPM, which means that the motor can rotate 3,600 revolutions per minute.

Frequency (Hz) refers to the frequency of the alternating current (AC) is the number of cycles per second in an AC sine wave. Frequency is the rate at which current changes direction per second, in the international measure Hz as the unit, we use 50Hz or 60Hz in the general worldwide.

RPM formula: RPM= Hz x 60(sec/min) x 2 ÷ number of poles

Therefore, under normal circumstances, when the frequency is 60Hz, 2P runs 3600 rpm, 4P runs 1800 rpm, 6P runs 1200 rpm, and so on. It can be seen from the formula that the number of poles, frequency and rotational speed are closely related to each other.

Voltage (V)

The voltage is proportional to RPM, that is, the higher the input voltage, the faster the motor rotates; the lower the input voltage, the slower the motor rotates.

IP Rating& Install Location

IP rating is usually marked with IPXX, such as IP54, IP55, IP56, etc. The first number after it represents the protection against contact and intrusion of solid foreign objects, and the second number represents the protection against ingress of liquid.

The motor can be installed indoors or outdoors according to the IP rating, depending on whether it can resist damage caused by wind, sun, rain, as well as customer operation requirements, noise problems and other conditions.

Energy Efficiency Index

International Efficiency is defined by the International Electrotechnical Commission (IEC), and the energy efficiency levels are divided into IE1, IE2, IE3, and IE4. The larger the number, the better the efficiency and the more power saving.

The above are the relevant specifications that must be referred to when selecting a motor. Next, the differences and applications of general motors, inverter duty motors and explosion-proof motors will be introduced.
