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.

Can Clamp Couplings Be Used in High-Temperature or Corrosive Environments?

Yes, clamp couplings are designed to be versatile and can be used in a wide range of environments, including high-temperature and corrosive conditions. However, their suitability depends on the specific material and coating used in the construction of the coupling.

In high-temperature environments, clamp couplings made from materials such as stainless steel or high-temperature alloys are commonly used. These materials have excellent heat resistance and can withstand elevated temperatures without losing their structural integrity. It is essential to choose a clamp coupling with a temperature rating that exceeds the operating temperature of the application to ensure safe and reliable performance.

In corrosive environments where exposure to chemicals, moisture, or other corrosive substances is a concern, selecting a corrosion-resistant material is critical. Stainless steel clamp couplings, particularly those made from 316-grade stainless steel, are widely used in such conditions due to their superior corrosion resistance. For more aggressive corrosive environments, special coatings or surface treatments can be applied to further enhance the coupling’s resistance to corrosion.

It is essential to consider the specific requirements of the application when selecting a clamp coupling for use in high-temperature or corrosive environments. Factors such as temperature, humidity, exposure to chemicals, and the presence of abrasive substances should be taken into account. Consulting with coupling manufacturers or industry experts can help in choosing the most suitable clamp coupling for the intended application.

Clamp Couplings and Damping Vibrations/Noise

Yes, clamp couplings can help dampen vibrations and reduce noise in mechanical systems to some extent. While not specifically designed as vibration isolators, clamp couplings can mitigate vibrations and noise due to their unique design and material properties.

The design of clamp couplings involves a split hub with screws that securely fasten around the shafts. This design offers several benefits:

  1. Damping Effect: The material of the coupling can absorb and dampen some of the vibrations generated by rotating equipment. Elastomeric elements or flexible materials used in some clamp couplings can help attenuate vibrations.
  2. Reduction of Resonance: Vibrations in rotating machinery can sometimes lead to resonance, causing excessive oscillations. Clamp couplings can help break the resonance cycle and prevent amplification of vibrations.
  3. Torsional Compliance: Some clamp couplings exhibit a degree of torsional compliance, which means they can tolerate small angular misalignments and dampen torsional vibrations.
  4. Transmissible Torque Variation: In some cases, clamp couplings can absorb torque spikes or variations, reducing the impact of sudden changes in load.

While clamp couplings can provide some level of vibration and noise reduction, their primary function is to transmit torque and accommodate misalignment between shafts. For more demanding vibration isolation or noise reduction applications, specialized components such as flexible couplings with damping features or dedicated vibration isolation mounts may be more suitable.

It is essential to consider the specific requirements of the mechanical system and consult with experts to determine the most appropriate coupling or isolator for achieving the desired level of vibration and noise reduction.

Handling Misalignment with Clamp Couplings

Yes, clamp couplings are designed to handle certain degrees of misalignment between shafts effectively. They can accommodate both angular and parallel misalignments, making them versatile for various mechanical systems.

The design of clamp couplings allows for a certain degree of flexibility and forgiveness in the coupling’s connection. When the shafts are not perfectly aligned due to angular or parallel misalignment, the clamp coupling can compensate for these variations.

The main factors contributing to the clamp coupling’s ability to handle misalignment are:

  • Flexible Material: Clamp couplings are often made of materials like aluminum, stainless steel, or other alloys with some elasticity. This flexibility enables them to absorb and compensate for minor misalignments.
  • Split Design: Clamp couplings usually have a split design with one or more screws or bolts that can be tightened to secure the coupling around the shafts. This design allows for easy installation and adjustment, making it possible to accommodate slight misalignments during assembly.
  • Tightening Mechanism: The screws or bolts used to fasten the clamp coupling can be tightened to the appropriate torque, providing a secure connection while still allowing for a certain amount of movement to handle misalignment.

However, it’s important to note that clamp couplings have limitations when it comes to misalignment. Excessive misalignment can lead to increased wear on the coupling components and shafts, reducing the coupling’s lifespan and potentially causing failure. Therefore, it’s essential to ensure that the misalignment does not exceed the coupling’s specified limits.

For more significant misalignments or applications with constant large misalignments, flexible couplings like elastomeric couplings or gear couplings may be more suitable. It’s crucial to select the appropriate coupling type based on the specific misalignment requirements of the mechanical system.

In conclusion, while clamp couplings can handle certain degrees of misalignment effectively, it is essential to stay within the recommended misalignment limits to maintain the coupling’s performance and longevity.
