Software Case

Standard circumstance of diaphragm coupling applied to variable frequency pace manage gear

JMB kind coupling is used to Daqing Oilfield Thermal Electricity Plant

According to the needs of Daqing Electric Energy Company, Daqing Oilfield Thermal Power Plant should dynamically adjust the electrical power generation according to the load of the power grid and marketplace need, and have out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by Shenyang Motor Factory. The pace control manner after altering the frequency is handbook management. Push the button velocity to enhance 10RPM or fall 10RPM. The coupling is even now the first elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is frequently destroyed, which directly impacts the regular power era.

It is identified via examination that in the approach of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the velocity regulation process (the diameter of the enthusiast impeller is 3.3 meters) and is minimize off, which has excellent damage to the motor and the fan.

Later on, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing facility (patent number: ZL.99246247.nine). Right after one hour of destructive experiment and much more than one yr of operation check, the equipment is operating really well, and there is no Substitute the diaphragm. 12 models have been rebuilt and the procedure is in very good issue.
