Typical case of diaphragm coupling applied to variable frequency velocity handle tools

JMB sort coupling is utilized to HangCZPT Oilfield Thermal Power Plant

In accordance to the needs of HangCZPT CZPT Electricity CZPT, HangCZPT Oilfield Thermal Energy Plant ought to dynamically alter the electricity era in accordance to the load of the power grid and marketplace demand, and carry out the transformation of the frequency converter and the suction supporter. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by HangCZPT Motor Factory. The velocity control mode following changing the frequency is manual management. Push the button speed to enhance 10RPM or drop 10RPM. The coupling is nonetheless the unique elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is regularly broken, which right has an effect on the regular electrical power technology.

It is located through evaluation 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 supporter impeller is three.3 meters) and is reduce off, which has excellent injury to the motor and the admirer.

Later on, they switched to the JMB460 double-diaphragm wheel-kind coupling of our manufacturing unit (patent amount: ZL.99246247.9). Soon after one hour of damaging experiment and much more than one particular year of operation examination, the tools is running extremely properly, and there is no Exchange the diaphragm. 12 models have been rebuilt and the procedure is in very good issue.
