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.

Is it Possible to Replace a Motor Coupling Without Professional Assistance?

Yes, it is possible to replace a motor coupling without professional assistance, but it requires some mechanical knowledge and proper tools. Here are the steps to replace a motor coupling:

1. Safety First:

Before attempting any maintenance or replacement, ensure the motor and driven equipment are turned off and disconnected from the power source to prevent accidents.

2. Identify the Coupling Type:

Determine the type of motor coupling currently installed in the system. Different coupling types may have slightly different installation methods.

3. Gather Necessary Tools:

Collect the necessary tools, such as wrenches, socket set, screwdrivers, and any other specific tools required for the particular coupling type.

4. Remove Fasteners:

Loosen and remove the fasteners that secure the coupling to the motor and driven equipment shafts. Keep track of the fasteners to ensure they are reinstalled correctly.

5. Disconnect the Coupling:

Disconnect the coupling from both the motor and driven equipment shafts. Depending on the coupling type, this may involve sliding the coupling off the shafts or unbolting it from the flanges.

6. Inspect the Coupling:

Inspect the old coupling for signs of wear, damage, or misalignment. This assessment will help determine if the coupling replacement is necessary.

7. Install the New Coupling:

Place the new coupling onto the motor and driven equipment shafts, ensuring it fits properly and aligns with any keyways or grooves.

8. Reattach Fasteners:

Tighten and secure the fasteners to hold the new coupling in place. Follow the manufacturer’s recommended torque values for the specific coupling model.

9. Perform Trial Run:

Before full operation, perform a trial run to check the coupling’s performance and ensure everything is working correctly. Monitor for any abnormal vibrations or noises.

10. Regular Maintenance:

After replacement, follow regular maintenance practices to inspect the coupling and the entire power transmission system for any signs of wear or issues.

While it is possible to replace a motor coupling without professional assistance, keep in mind that improper installation or failure to diagnose other underlying issues may lead to further problems. If you are unsure about the process or encounter difficulties during the replacement, it is always best to seek the help of a qualified technician or engineer to ensure a successful and safe coupling replacement.
