Application Situation

Normal circumstance of diaphragm coupling applied to variable frequency velocity control products

JMB sort coupling is utilized to Daqing Oilfield Thermal Electrical power Plant

According to the specifications of Daqing Electrical Electricity Corporation, Daqing Oilfield Thermal Electrical power Plant need to dynamically modify the energy generation in accordance to the load of the energy grid and market place desire, and carry out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable pace motor matched by Shenyang Motor Manufacturing unit. The pace manage manner soon after altering the frequency is handbook management. Press the button speed to increase 10RPM or fall 10RPM. The coupling is even now the first elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is often destroyed, which immediately has an effect on the regular electricity generation.

It is discovered by means of evaluation 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 supporter impeller is three.three meters) and is minimize off, which has great damage to the motor and the supporter.

Later, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing unit (patent quantity: ZL.99246247.9). Soon after 1 hour of destructive experiment and more than one yr of operation take a look at, the equipment is running really nicely, and there is no Exchange the diaphragm. 12 units have been rebuilt and the operation is in very good situation.
