Application Circumstance

Common circumstance of diaphragm coupling used to variable frequency speed control gear

JMB type coupling is utilized to HangCZPT Oilfield Thermal Electrical power Plant

According to the requirements of HangCZPT CZPT Energy CZPT, HangCZPT Oilfield Thermal Electrical power Plant need to dynamically change the electrical power technology in accordance to the load of the energy grid and market place demand, and have out the transformation of the frequency converter and the suction supporter. The motor was at first a 1600KW, 730RPM non-frequency variable velocity motor matched by HangCZPT Motor Manufacturing unit. The speed management manner following altering the frequency is manual control. Press the button speed to improve 10RPM or fall 10RPM. The coupling is nevertheless the first elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is regularly ruined, which right impacts the regular power era.

It is identified by way of investigation that in the method of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the speed regulation procedure (the diameter of the admirer impeller is three.three meters) and is reduce off, which has fantastic damage to the motor and the enthusiast.

Later, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing facility (patent quantity: ZL.99246247.nine). Following 1 hour of harmful experiment and much more than one yr of operation examination, the products is managing very properly, and there is no Change the diaphragm. twelve units have been rebuilt and the procedure is in excellent situation.
