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.

Thermal Considerations and Limits for Continuous Operations with Servo Couplings

Servo couplings, like many mechanical components, can experience temperature changes during continuous operation. It is essential to consider thermal factors and establish temperature limits to ensure the proper functioning and longevity of the couplings. Here are the key thermal considerations and limits:

  • Temperature Ratings:

    Manufacturers provide temperature ratings for servo couplings, indicating the range of temperatures in which the couplings can operate safely. It is crucial to stay within these specified temperature limits to prevent potential damage to the coupling or its connected components.

  • Heat Dissipation:

    Servo couplings may generate heat during operation due to friction and torsional loads. The ability of the coupling to dissipate heat effectively helps prevent excessive temperature rise. Choosing a coupling with suitable materials and design can improve heat dissipation.

  • Continuous vs. Intermittent Operation:

    Servo couplings may have different thermal limits for continuous operation compared to intermittent or start-stop operations. It is essential to ensure that the coupling’s temperature ratings are suitable for the application’s specific mode of operation.

  • Environment:

    The operating environment can also impact the thermal performance of the servo coupling. High ambient temperatures, confined spaces, or inadequate ventilation can elevate the temperature around the coupling, potentially pushing it beyond its limits.

  • Lubrication:

    Proper lubrication of the coupling’s components can help reduce friction and heat generation. Using the right lubricant and ensuring regular maintenance can contribute to the coupling’s optimal thermal performance.

  • Thermal Expansion:

    Thermal expansion of materials can lead to dimensional changes in the coupling. If not accounted for, this expansion can cause misalignment or interference with other components. Understanding the thermal expansion properties of the coupling materials is crucial for precise system design.

  • Overheating Prevention:

    To prevent overheating, monitoring the coupling’s temperature during continuous operations is advisable. Implementing temperature sensors or thermal monitoring systems can help detect abnormal temperature increases and trigger appropriate actions, such as reducing operating speeds or shutting down the system temporarily.

  • Material Selection:

    Choosing materials with appropriate thermal properties is vital for withstanding continuous operations. Some materials are more resistant to high temperatures and thermal cycling, making them suitable for applications with demanding thermal conditions.

By considering these thermal considerations and adhering to the specified temperature limits, users can ensure that servo couplings operate reliably and efficiently during continuous operations, avoiding potential failures and ensuring the longevity of the motion control system.

Handling Angular and Axial Misalignments Simultaneously with Servo Couplings

Servo couplings are designed to handle both angular and axial misalignments simultaneously, making them versatile components for motion control systems. Here’s how they achieve this:

  • Angular Misalignment: Angular misalignment occurs when the motor shaft and the driven load shaft are not perfectly aligned, resulting in an angular offset between them. Servo couplings with flexible elements, such as bellows or beam couplings, can accommodate angular misalignment without inducing excessive stress on the components.
  • Axial Misalignment: Axial misalignment happens when there is a parallel displacement between the motor and the driven load along the shaft axis. Servo couplings with flexible elements allow for axial movement, absorbing any axial misalignment while maintaining torque transmission.
  • Combination of Both: Servo couplings are designed to handle the combination of angular and axial misalignments simultaneously. As the flexible elements of the coupling can move in multiple directions, they can compensate for both angular and axial deviations, ensuring smooth and efficient power transmission.

The ability of servo couplings to handle both angular and axial misalignments is vital in many motion control applications. It allows for greater flexibility in design and installation, as well as improved system performance and reduced wear on the components.

How to Choose the Right Servo Coupling for Specific Motion Control Applications

Choosing the right servo coupling is crucial for achieving optimal performance and reliability in motion control applications. Here are the key steps to help you select the most suitable servo coupling for your specific application:

  1. Identify Application Requirements: Start by understanding the specific requirements of your motion control application. Consider factors such as torque and speed requirements, misalignment compensation needed, environmental conditions, and the level of precision and repeatability required.
  2. Consider Torque Capacity: Determine the maximum torque that the servo coupling needs to transmit. Choose a coupling with a torque capacity that exceeds the peak torque in your application to ensure safety and prevent premature failure.
  3. Evaluate Misalignment Compensation: Assess the type and amount of misalignment that may occur between the servo motor and the driven load. Different coupling types offer varying degrees of misalignment compensation, such as angular, axial, and parallel misalignment. Select a coupling that can accommodate the expected misalignments to prevent excessive loads on the motor and bearings.
  4. Examine Speed and Precision: Consider the speed at which the application will operate and the required level of precision. High-speed applications may require couplings with low inertia and high torsional stiffness to minimize vibration and ensure accurate motion control.
  5. Review Backlash and Torsional Stiffness: Backlash can impact motion accuracy, especially in reversing applications. Look for couplings with low backlash to maintain precise bidirectional control. Additionally, evaluate the torsional stiffness of the coupling to ensure efficient power transmission and response.
  6. Check Environmental Compatibility: Consider the operating environment, including temperature, humidity, and exposure to chemicals or contaminants. Choose a servo coupling made from materials that can withstand the specific environmental conditions without compromising performance or lifespan.
  7. Assess Installation and Maintenance: Evaluate the ease of installation and any maintenance requirements of the coupling. Some couplings may require periodic lubrication or replacement of elastomeric elements. Opt for a coupling that is easy to install and maintain to minimize downtime and servicing costs.
  8. Seek Expert Advice: If you are unsure about the best servo coupling for your application, consult with experts or engineers experienced in motion control systems. They can provide valuable insights and recommend suitable couplings based on your specific needs.

By carefully considering these factors and following the steps outlined above, you can choose the right servo coupling that matches your motion control application’s requirements. A well-chosen coupling will ensure smooth and accurate motion, improve system performance, and extend the lifespan of your servo motor and driven load.
