Application Case

Typical case of diaphragm coupling applied to variable frequency speed control equipment

JMB type coupling is applied to HangZhou Oilfield Thermal Power Plant

According to the requirements of HangZhou Electric Power Corporation, HangZhou Oilfield Thermal Power Plant should dynamically adjust the power generation according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The speed control mode after changing the frequency is manual control. Press the button speed to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is frequently damaged, which directly affects the normal power generation.

It is found through analysis that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the fan impeller is 3.3 meters) and is cut off, which has great damage to the motor and the fan.

Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent number: ZL.99246247.9). After 1 hour of destructive experiment and more than 1 year of operation test, the equipment is running very well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in good condition.

What are the maintenance requirements for fluid drive couplings to ensure optimal performance?

Proper maintenance is crucial to ensure the optimal performance and extended service life of fluid drive couplings. Regular maintenance practices help identify and address potential issues early, preventing costly breakdowns and ensuring the efficiency of power transmission systems. The maintenance requirements for fluid drive couplings include:

  • Fluid Level Check: Regularly check the hydraulic fluid level in the coupling. Ensure that the fluid level is within the manufacturer’s recommended range. Low fluid levels can lead to decreased torque transmission and affect the coupling’s performance.
  • Fluid Quality: Monitor the condition of the hydraulic fluid regularly. Contaminated or degraded fluid can adversely impact the coupling’s performance. Replace the fluid as per the manufacturer’s guidelines or if signs of contamination are observed.
  • Seals and Gaskets: Inspect the seals and gaskets for signs of wear, leaks, or damage. Faulty seals can lead to fluid leakage, reducing the coupling’s efficiency and potentially causing damage to other components in the system.
  • Alignment Check: Periodically check the alignment of the driving and driven shafts. Misalignment can result in increased wear and reduced performance of the fluid drive coupling. Proper alignment ensures optimal torque transmission and prevents premature failure.
  • Overload Protection: Test the slip mechanism to ensure it is functioning correctly. The slip mechanism should engage during overload conditions to protect the coupling and connected machinery from excessive stresses.
  • Coupling Bolts: Inspect and tighten the coupling bolts as per the manufacturer’s recommendations. Loose bolts can result in misalignment and reduced coupling efficiency.
  • Lubrication: Some fluid drive couplings may have specific lubrication requirements. Follow the manufacturer’s guidelines for lubricating the coupling components, if applicable.
  • Temperature Monitoring: Monitor the operating temperature of the fluid drive coupling. Excessive heat can impact the hydraulic fluid’s viscosity and degrade the coupling’s performance.
  • Periodic Inspection: Conduct regular visual and functional inspections of the fluid drive coupling. Look for any signs of abnormal wear, damage, or unusual noises during operation.

It is essential to refer to the manufacturer’s maintenance guidelines and recommendations specific to the fluid drive coupling model. Adhering to the prescribed maintenance schedule and procedures ensures that the coupling remains in optimal condition and delivers reliable performance over its operational life.

By following these maintenance practices, users can minimize downtime, avoid costly repairs, and ensure the fluid drive coupling continues to contribute to the efficient and safe operation of the power transmission system.

Can Fluid Drive Couplings Be Retrofitted Into Existing Systems to Improve Performance?

Yes, fluid drive couplings can be retrofitted into existing systems to improve performance and achieve various benefits. Fluid drive couplings, also known as hydraulic couplings, hydrodynamic couplings, or fluid couplings, are highly versatile and can be used in a wide range of applications.

Retrofitting a fluid drive coupling into an existing system offers several advantages:

  • Reduced Shock Loads: Fluid drive couplings have the ability to cushion shock loads and dampen torsional vibrations. By retrofitting a fluid coupling, the system can experience smoother starts and stops, reducing stress on the connected equipment and improving overall system reliability.
  • Overload Protection: Fluid couplings act as torque limiters, providing protection against sudden torque spikes and overloads. This helps safeguard sensitive machinery and prevents damage to the system during unexpected events.
  • Energy Savings: Fluid drive couplings allow for gradual engagement, which reduces power peaks during starting and stopping operations. This leads to energy savings, especially in applications where frequent starts and stops are required.
  • Flexible Power Transmission: Fluid couplings can accommodate slight misalignments between the driving and driven shafts, making them suitable for retrofitting into systems with existing misalignment issues.
  • Increased System Lifespan: By reducing mechanical stresses and wear on the connected equipment, fluid drive couplings can extend the overall lifespan of the system, leading to lower maintenance costs and increased productivity.
  • Smooth and Quiet Operation: Fluid drive couplings provide smooth and quiet power transmission, reducing noise levels and enhancing the comfort of operators and personnel working near the equipment.

When retrofitting a fluid drive coupling, it is essential to consider factors such as the specific application requirements, the torque and speed characteristics of the existing system, and the compatibility of the coupling with the connected equipment. Proper alignment and installation are also crucial to ensure optimal performance and longevity.

Overall, retrofitting fluid drive couplings into existing systems can be a cost-effective and beneficial solution to enhance performance, improve efficiency, and protect valuable machinery in various industrial applications.

Can you explain the working principle of a fluid drive coupling and its advantages over other coupling types?

A fluid drive coupling, also known as a hydraulic coupling, is a type of coupling used to transmit power between two shafts in a machinery system. It operates on the principle of hydrodynamic power transmission, utilizing hydraulic fluid to transfer torque and rotational motion from the driving shaft to the driven shaft.

The working principle of a fluid drive coupling involves the following key elements:

  • Driving Impeller (Pump): The fluid drive coupling consists of a driving impeller, also called the pump, attached to the driving shaft. When the driving shaft rotates, it causes the driving impeller to rotate as well.
  • Driven Impeller (Turbine): The driven impeller, also known as the turbine, is connected to the driven shaft. As the fluid in the coupling circulates, it imparts rotational motion to the driven impeller.
  • Hydraulic Fluid: The coupling is filled with hydraulic fluid, typically oil. When the driving impeller rotates, it creates a flow of hydraulic fluid within the casing.

As the hydraulic fluid moves from the driving impeller to the driven impeller, it generates a hydraulic force that drives the driven impeller to rotate. This movement of fluid between the impellers allows the transfer of torque from the driving shaft to the driven shaft without any direct mechanical contact between them.

Advantages of Fluid Drive Coupling over other coupling types include:

  • Smooth Operation: Fluid drive couplings offer smooth and gradual acceleration, minimizing shock loads on the machinery and reducing wear on mechanical components. This results in improved system longevity and reduced maintenance requirements.
  • Torque Amplification: During start-up or when the driven shaft encounters resistance, fluid drive couplings can provide torque amplification, allowing the driven shaft to handle higher loads without stalling the driving shaft.
  • Overload Protection: Fluid drive couplings can slip under excessive load conditions, absorbing the excess energy and protecting the machinery from damage. This feature acts as a safety mechanism and prevents sudden overloads.
  • Speed Regulation: By adjusting the input speed of the driving shaft, fluid drive couplings can regulate the speed of the driven shaft. This feature is beneficial in applications where precise control of output speed is necessary.
  • No Mechanical Wear: Since fluid drive couplings do not have any physical contact between the driving and driven shafts, there is minimal mechanical wear, reducing the need for frequent maintenance and replacement of coupling components.
  • Isolation of Vibrations and Noise: Fluid drive couplings dampen vibrations and noise in the power transmission system, resulting in quieter operation and improved comfort in the surrounding environment.
  • High Misalignment Tolerance: Fluid drive couplings can accommodate axial and angular misalignments between the driving and driven shafts, reducing the risk of component failure due to misalignment issues.

Fluid drive couplings find application in various industries, including automotive, construction, industrial machinery, and marine, where they contribute to efficient power transmission, improved system performance, and enhanced safety during operation.

It’s essential to consider the specific requirements of the machinery system and the advantages offered by fluid drive couplings when selecting the appropriate coupling type for a particular application. Proper installation, maintenance, and monitoring of the fluid drive coupling ensure continued reliable and efficient operation of the machinery or equipment.
