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.

fluid drive coupling

How do fluid drive couplings contribute to reducing shocks and vibrations in mechanical systems?

Fluid drive couplings play a significant role in reducing shocks and vibrations in mechanical systems by absorbing and dampening undesirable dynamic forces. The unique design and operating principle of fluid drive couplings allow them to mitigate the impact of sudden changes in load or operating conditions.

Here are the ways in which fluid drive couplings contribute to shock and vibration reduction:

  • Torque Dampening: Fluid drive couplings act as torque dampeners, reducing the rapid transmission of torque fluctuations from the driving to the driven element. When there is a sudden change in the torque demand, the hydraulic fluid in the coupling absorbs and dissipates the excess energy, preventing sudden jerks and shocks from propagating through the system.
  • Flexible Coupling: Fluid drive couplings provide flexibility in the power transmission system. This flexibility allows the coupling to absorb misalignments and compensate for small angular or axial deviations between the driving and driven shafts. As a result, vibrations caused by misalignment are minimized, leading to smoother operation.
  • Resonance Damping: Fluid drive couplings can help dampen vibrations caused by resonance in mechanical systems. Resonance occurs when the system’s natural frequency matches the excitation frequency, leading to excessive vibrations. The damping effect of the hydraulic fluid helps reduce the amplitude of the vibrations, preventing potential damage to the system.
  • Overload Protection: In scenarios of sudden overloads or shock loads, fluid drive couplings can slip to protect the connected machinery from excessive stresses. This slip feature acts as a safety mechanism, preventing damage to the equipment and reducing the impact of the shock load on the system.
  • No Metal-to-Metal Contact: Unlike some mechanical couplings, fluid drive couplings have no metal-to-metal contact between the driving and driven elements. The hydraulic fluid acts as a lubricant and cushion, reducing friction and wear, which can generate vibrations and noise in mechanical systems.
  • Viscous Damping: The hydraulic fluid in the coupling provides viscous damping, dissipating energy as heat when the coupling experiences vibrations. This viscous damping effect helps reduce the amplitude and duration of mechanical vibrations.

By minimizing shocks and vibrations, fluid drive couplings improve the overall performance and reliability of mechanical systems. The reduction in dynamic forces helps decrease wear and tear on system components, extending their service life and reducing maintenance requirements.

It is essential to select the appropriate fluid drive coupling based on the specific application’s requirements to ensure optimal shock and vibration reduction. Regular maintenance and monitoring of the coupling’s condition also help maintain its effectiveness in dampening shocks and vibrations over time.

How Fluid Drive Couplings Ensure Efficient Power Transmission and Smooth Operation

Fluid drive couplings, also known as hydraulic couplings or fluid couplings, are designed to facilitate efficient power transmission and ensure smooth operation in various industrial applications. Here’s how they achieve these objectives:

  1. Fluid Medium: Fluid drive couplings contain a fluid medium, typically hydraulic oil, inside a sealed chamber. When the driving shaft rotates, it imparts motion to the fluid.
  2. Centrifugal Action: As the fluid is set in motion by the driving shaft, it creates a centrifugal force that causes the fluid to move outward towards the housing walls.
  3. Torque Transmission: The moving fluid then comes in contact with the blades or vanes attached to the driven shaft. This interaction transmits torque from the driving shaft to the driven shaft, allowing power transmission.
  4. Smooth Start: During startup, the fluid coupling provides a controlled, gradual acceleration to the driven shaft. This soft start minimizes shock loads on the connected equipment, reducing wear and tear and preventing damage to the system.
  5. Torque Converter: In some applications, fluid drive couplings function as torque converters, especially in automatic transmissions. They enable efficient power transfer in a wide range of speeds, allowing the engine to operate efficiently at various load conditions.
  6. Torsional Vibration Damping: Fluid drive couplings act as torsional vibration dampers, absorbing vibrations and shocks caused by sudden changes in load or speed. This feature protects the connected equipment and improves overall system reliability.
  7. Overload Protection: Fluid drive couplings offer overload protection by slipping when the load exceeds a certain threshold. This prevents mechanical damage and helps safeguard the system from sudden shocks or blockages.
  8. Energy Efficiency: By providing a soft start and minimizing power loss during transmission, fluid drive couplings contribute to energy efficiency in various applications.

Overall, fluid drive couplings play a crucial role in ensuring efficient power transmission, protecting equipment from damage, and enabling smooth operation in a wide range of industrial processes.

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.
