Software Situation

Normal situation of diaphragm coupling applied to variable frequency speed handle products

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

In accordance to the needs of HangCZPT CZPT Electricity CZPT, HangCZPT Oilfield Thermal Electricity Plant need to dynamically alter the energy generation according to the load of the electrical power grid and industry need, and carry out the transformation of the frequency converter and the suction supporter. The motor was originally a 1600KW, 730RPM non-frequency variable pace motor matched by HangCZPT Motor Manufacturing unit. The speed control mode after shifting the frequency is manual control. Push the button velocity to increase 10RPM or drop 10RPM. The coupling is nevertheless the first elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is usually damaged, which straight influences the standard energy technology.

It is discovered by means of investigation that in the approach of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the pace regulation method (the diameter of the supporter impeller is 3.3 meters) and is cut off, which has fantastic harm to the motor and the enthusiast.

Later on, they switched to the JMB460 double-diaphragm wheel-kind coupling of our manufacturing unit (patent quantity: ZL.99246247.nine). Right after 1 hour of harmful experiment and more than one year of operation take a look at, the gear is working very nicely, and there is no Exchange the diaphragm. 12 units have been rebuilt and the operation is in good problem.
