Normal case of diaphragm coupling applied to variable frequency speed manage equipment
JMB kind coupling is applied to HangZhou Oilfield Thermal Power Plant
According to the specifications of HangZhouEPTPower Corporation, HangZhou Oilfield Thermal Energy Plant should dynamically modify the electrical power generation according to the load of the electricity grid and market demand from customers, and have out the transformation of the frequency converter and the suction supporter. The motor was initially a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Manufacturing unit. The velocity manage manner right after shifting the frequency is guide control. Press the button speed to increase 10RPM or fall 10RPM. The coupling is even now the unique elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is usually broken, which immediately influences the typical electrical power technology.
It is found by way of analysis that in the process of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the speed regulation method (the diameter of the fan impeller is 3.3 meters) and is minimize off, which has fantastic injury to the motor and the admirer.
Later on, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing unit (patent quantity: ZL.99246247.nine). Soon after one hour of damaging experiment and far more than one particular yr of procedure examination, the tools is managing extremely nicely, and there is no Exchange the diaphragm. twelve units have been rebuilt and the procedure is in excellent situation.
