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.

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.

What are the different types of fluid drive couplings used in various industrial applications?

Fluid drive couplings come in various types, each designed to suit specific industrial applications and power transmission requirements. Here are some of the different types of fluid drive couplings commonly used in various industries:

  • Constant-Fill Fluid Couplings: Constant-fill fluid couplings have a fixed amount of hydraulic fluid inside the casing. These couplings offer smooth acceleration and deceleration and provide torque amplification during start-up. They are often used in applications requiring consistent speed regulation and overload protection, such as conveyor systems and crushers.
  • Variable-Fill Fluid Couplings: Variable-fill fluid couplings allow manual adjustment of the hydraulic fluid level within the casing. By changing the fill level, the coupling can vary the amount of slip between the driving and driven shafts, enabling precise control over the output speed. These couplings are suitable for applications that require speed control, such as mixers, agitators, and cooling tower fans.
  • Delayed-Fill Fluid Couplings: Delayed-fill fluid couplings have a time-delayed filling mechanism that controls the fluid transfer between the driving and driven impellers. They are used in applications where a gradual start-up is necessary to reduce shock loads, such as in large centrifugal pumps and compressors.
  • Hydrodynamic Torque Converters: Hydrodynamic torque converters are a type of fluid coupling with an additional stator element. The stator redirects the fluid flow, improving the efficiency of power transmission and providing a higher torque output. These couplings are commonly used in automotive applications, such as automatic transmissions in vehicles.
  • Magnetic Fluid Couplings: Magnetic fluid couplings use magnetic fields to transfer torque without physical contact between the driving and driven impellers. These couplings offer a hermetically sealed design, making them suitable for applications where preventing fluid leakage is critical, such as in pumps and marine propulsion systems.
  • Constant-Fill Fluid Couplings with Lock-Up: These couplings combine the characteristics of a constant-fill fluid coupling with the ability to lock-up the driving and driven impellers, creating a solid mechanical connection when required. They are commonly used in industrial drivetrains to improve overall efficiency and reduce energy losses.
  • Fluid Couplings with Integrated Clutches: These couplings incorporate both the hydrodynamic power transmission of fluid couplings and the clutching action of mechanical clutches. They provide smooth start-up and can handle high torque loads, making them suitable for heavy-duty applications like metal forming presses and mining equipment.

Each type of fluid drive coupling offers unique advantages and is selected based on the specific requirements of the industrial application. When choosing a fluid drive coupling, factors such as torque capacity, speed range, slip control, and efficiency should be carefully considered to ensure optimal performance and reliability in the intended application.

It’s crucial to consult with experienced fluid power engineers or coupling manufacturers to determine the most suitable type of fluid drive coupling for a particular industrial application. Proper selection and installation of the right fluid drive coupling can significantly enhance the efficiency, safety, and longevity of the machinery or equipment.
