Application Case

Typical case of diaphragm coupling applied to variable frequency speed control equipment

JMB type coupling is applied to Daqing Oilfield Thermal Power Plant

According to the requirements of Daqing Electric Power Corporation, Daqing 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 Shenyang 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 one 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.
