Application Situation

Standard situation of diaphragm coupling applied to variable frequency pace control equipment

JMB variety coupling is applied to HangCZPT Oilfield Thermal Energy Plant

According to the requirements of HangCZPT CZPT Electricity CZPT, HangCZPT Oilfield Thermal Power Plant should dynamically alter the electricity era in accordance to the load of the power grid and industry need, and have out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by HangCZPT Motor Manufacturing unit. The velocity control manner after shifting the frequency is handbook manage. Push the button velocity to improve 10RPM or fall 10RPM. The coupling is even now the original elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is regularly damaged, which immediately impacts the typical electricity generation.

It is discovered by means of analysis that in the procedure of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the pace regulation procedure (the diameter of the fan impeller is 3.three meters) and is minimize off, which has great damage to the motor and the admirer.

Later on, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing unit (patent amount: ZL.99246247.9). Following one hour of damaging experiment and a lot more than 1 12 months of operation test, the tools is working extremely effectively, and there is no Exchange the diaphragm. 12 models have been rebuilt and the procedure is in very good condition.
