Standard situation of diaphragm coupling applied to variable frequency speed control gear
JMB variety coupling is used to HangCZPT Oilfield Thermal Electricity Plant
According to the needs of HangCZPT CZPT Power CZPT, HangCZPT Oilfield Thermal Power Plant need to dynamically adjust the energy technology in accordance to the load of the electricity grid and industry need, and have out the transformation of the frequency converter and the suction enthusiast. The motor was initially a 1600KW, 730RPM non-frequency variable speed motor matched by HangCZPT Motor Manufacturing facility. The velocity manage mode soon after modifying the frequency is manual control. Push the button velocity to increase 10RPM or drop 10RPM. The coupling is still the first elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is regularly destroyed, which immediately has an effect on the regular electrical power era.
It is located by means 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 fan impeller is 3.3 meters) and is cut off, which has wonderful damage to the motor and the fan.
Afterwards, they switched to the JMB460 double-diaphragm wheel-type coupling of our manufacturing facility (patent amount: ZL.99246247.9). Right after one hour of harmful experiment and a lot more than one particular calendar year of procedure check, the products is managing extremely well, and there is no Exchange the diaphragm. 12 units have been rebuilt and the procedure is in great problem.
