Normal situation of diaphragm coupling used to variable frequency speed control equipment
JMB sort coupling is applied to HangCZPT Oilfield Thermal Electrical power Plant
According to the requirements of HangCZPT CZPT Electricity CZPT, HangCZPT Oilfield Thermal Power Plant need to dynamically alter the energy generation according to the load of the energy grid and marketplace demand, and have out the transformation of the frequency converter and the suction fan. The motor was initially a 1600KW, 730RPM non-frequency variable velocity motor matched by HangCZPT Motor Manufacturing facility. The pace manage manner right after shifting the frequency is handbook handle. Press the button velocity to improve 10RPM or drop 10RPM. The coupling is still the unique elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is frequently damaged, which right impacts the regular electrical power generation.
It is found by means of investigation that in the method of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the pace regulation method (the diameter of the enthusiast impeller is 3.3 meters) and is lower off, which has great damage to the motor and the supporter.
Later, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing facility (patent quantity: ZL.99246247.9). Following one hour of harmful experiment and much more than a single calendar year of operation check, the gear is working very effectively, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in great issue.
