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.

Specific Safety Guidelines for Installing and Using Servo Couplings

Servo couplings are crucial components in motion control systems, and their installation and usage require adherence to specific safety guidelines to ensure safe operation and prevent accidents. Here are some essential safety considerations:

  1. Read the Manufacturer’s Instructions:

    Always read and follow the manufacturer’s installation and usage instructions for the specific servo coupling model. Each coupling may have unique requirements and limitations that need to be understood before installation.

  2. Inspect the Coupling:

    Prior to installation, inspect the servo coupling for any signs of damage or defects. Do not use a coupling that appears to be damaged, as it may compromise the overall performance and safety of the system.

  3. Proper Alignment:

    Ensure the correct alignment of the shafts before installing the servo coupling. Misalignment can cause excessive stress on the coupling and lead to premature failure.

  4. Secure Mounting:

    Ensure that the servo coupling is securely mounted to the shafts and other components. Use appropriate fasteners and follow torque specifications provided by the manufacturer.

  5. Use Safety Guards:

    In some applications, moving parts of the servo coupling may pose a risk of entanglement or pinch points. Consider using safety guards or covers to protect personnel from potential hazards.

  6. Stay within Load and Torque Ratings:

    Do not exceed the maximum load and torque ratings specified by the manufacturer. Overloading the servo coupling can lead to catastrophic failure.

  7. Regular Inspection and Maintenance:

    Perform regular inspections of the servo coupling and associated components. Check for wear, misalignment, and any other issues that may affect the coupling’s performance.

  8. Operating Environment:

    Consider the operating environment and choose a servo coupling material that can withstand the conditions, such as temperature, humidity, and exposure to chemicals.

  9. Electric Safety:

    If the servo coupling contains electrical components, follow electrical safety guidelines when installing and connecting these elements.

  10. Training and Awareness:

    Ensure that personnel involved in the installation, operation, and maintenance of the motion control system are adequately trained and aware of the safety guidelines and potential hazards.

Following these safety guidelines will help ensure the safe and efficient operation of the servo coupling and contribute to the overall safety of the motion control system and personnel involved.

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.

What is a Servo Coupling, and Its Role in Servo Motor Systems

A servo coupling is a specialized type of coupling used in servo motor systems to connect the servo motor shaft to the driven load. Servo motor systems are widely used in various industries for precise motion control applications, where accuracy, speed, and torque control are crucial. The servo coupling plays a vital role in ensuring the efficient transfer of motion and torque from the servo motor to the driven load while compensating for misalignments between the motor and load shafts.

The main functions and role of a servo coupling in a servo motor system are as follows:

  • Motion Transmission: The primary function of a servo coupling is to transmit motion from the shaft of the servo motor to the load. It connects the motor shaft to the driven load, such as a ball screw, gearbox, or another mechanical component, enabling the motor to drive and control the motion of the load precisely.
  • Torque Transmission: In addition to motion, the servo coupling also transfers torque from the motor to the load. As the servo motor generates rotational force (torque), the coupling efficiently transmits this torque to the driven load, allowing it to perform its intended motion with the required force.
  • Misalignment Compensation: Perfect alignment between the servo motor shaft and the load shaft is challenging to achieve in real-world applications. Any misalignment can cause detrimental effects, including increased wear, reduced performance, and premature failure. The servo coupling acts as a flexible element that can compensate for various types of misalignments, such as angular, parallel, and axial misalignments. This flexibility helps to maintain smooth and efficient power transmission even when the motor and load are not perfectly aligned.
  • Damping of Vibrations: Servo motor systems often operate at high speeds and with rapid changes in direction. These dynamic movements can generate vibrations that may adversely affect the performance and lifespan of the system. A well-designed servo coupling can dampen these vibrations, providing a more stable and controlled motion to the load, reducing the risk of damage or inaccuracies.
  • Backlash Minimization: Backlash refers to the play or gap between the teeth or components of the coupling when the direction of motion is reversed. Excessive backlash can result in lost motion and reduced precision. High-quality servo couplings are engineered to minimize backlash, ensuring accurate bidirectional motion control in the servo motor system.

Overall, a properly selected and installed servo coupling enhances the performance, efficiency, and reliability of servo motor systems. It protects sensitive components, such as bearings and motors, from excessive loads and vibrations, leading to extended equipment life and improved motion control capabilities.
