Application Situation

Standard situation of diaphragm coupling utilized to variable frequency velocity handle tools

JMB sort coupling is used to HangCZPT Oilfield Thermal Electrical power Plant

In accordance to the specifications of HangCZPT CZPT Electrical power CZPT, HangCZPT Oilfield Thermal Electricity Plant should dynamically adjust the electrical power generation according to the load of the electrical power grid and market demand from customers, and carry out the transformation of the frequency converter and the suction enthusiast. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by HangCZPT Motor Manufacturing unit. The pace control method following modifying the frequency is guide control. Press the button speed to boost 10RPM or fall 10RPM. The coupling is nonetheless the unique elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is frequently ruined, which right influences the regular electrical power generation.

It is discovered by means 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 approach (the diameter of the fan impeller is 3.3 meters) and is lower off, which has wonderful hurt to the motor and the fan.

Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our manufacturing facility (patent amount: ZL.99246247.nine). Soon after one hour of harmful experiment and far more than one year of procedure check, the tools is running really effectively, and there is no Replace the diaphragm. twelve models have been rebuilt and the procedure is in good problem.
