Application Case
Normal circumstance of diaphragm coupling applied to variable frequency pace management tools
JMB type coupling is used to HangCZPT Oilfield Thermal Energy Plant
In accordance to the requirements of HangCZPT CZPT Energy CZPT, HangCZPT Oilfield Thermal Electrical power Plant ought to dynamically change the electricity era according to the load of the electricity grid and market demand, and carry out the transformation of the frequency converter and the suction enthusiast. The motor was originally a 1600KW, 730RPM non-frequency variable pace motor matched by HangCZPT Motor Manufacturing unit. The velocity manage method right after modifying the frequency is handbook handle. Push the button pace to improve 10RPM or fall 10RPM. The coupling is nevertheless the unique elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is often destroyed, which directly influences the typical power era.
It is located by means of analysis that in the procedure of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the velocity regulation procedure (the diameter of the enthusiast impeller is 3.three meters) and is reduce off, which has excellent hurt to the motor and the fan.
Afterwards, they switched to the JMB460 double-diaphragm wheel-kind coupling of our factory (patent variety: ZL.99246247.9). After one hour of damaging experiment and more than one yr of procedure take a look at, the gear is working very well, and there is no Exchange the diaphragm. 12 units have been rebuilt and the procedure is in great situation.
