Software Case

Normal circumstance of diaphragm coupling utilized to variable frequency pace manage gear

JMB kind coupling is applied to Daqing Oilfield Thermal Electrical power Plant

In accordance to the demands of Daqing Electric Electrical power Corporation, Daqing Oilfield Thermal Electrical power Plant need to dynamically alter the power era according to the load of the electrical power grid and marketplace need, and have out the transformation of the frequency converter and the suction enthusiast. The motor was initially a 1600KW, 730RPM non-frequency variable velocity motor matched by Shenyang Motor Factory. The pace management manner following altering the frequency is manual manage. Push the button velocity to boost 10RPM or drop 10RPM. The coupling is still the authentic elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is usually ruined, which immediately impacts the standard electrical power generation.

It is identified by way of examination that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the pace regulation procedure (the diameter of the enthusiast impeller is 3.3 meters) and is reduce off, which has wonderful harm to the motor and the supporter.

Later on, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing unit (patent number: ZL.99246247.9). After one hour of destructive experiment and far more than a single calendar year of procedure examination, the tools is running extremely well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in excellent situation.
