Application Situation
Common case of diaphragm coupling used to variable frequency speed control tools
JMB variety coupling is applied to HangZhou Oilfield Thermal Power Plant
According to the specifications of HangZhouEPTPower Company, HangZhou Oilfield Thermal Power Plant should dynamically modify the electrical power era according to the load of the energy grid and marketplace demand from customers, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable pace motor matched by HangZhou Motor Factory. The pace control method after changing the frequency is handbook manage. Press the button pace to increase 10RPM or fall 10RPM. The coupling is still the unique elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is regularly ruined, which straight has an effect on the standard electricity generation.
It is discovered by means of evaluation that in the process of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the speed regulation procedure (the diameter of the enthusiast impeller is three.3 meters) and is reduce off, which has wonderful damage to the motor and the enthusiast.
Later, they switched to the JMB460 double-diaphragm wheel-kind coupling of our factory (patent quantity: ZL.99246247.nine). After 1 hour of damaging experiment and far more than one particular 12 months of operation check, the products is working really well, and there is no Replace the diaphragm. 12 models have been rebuilt and the operation is in excellent problem.
