Application Circumstance

Standard situation of diaphragm coupling used to variable frequency pace control products

JMB sort coupling is applied to HangEPT Oilfield Thermal EPTT Plant

According to the requirements of HangEPT Electric powered EPTT EPTT, HangEPT Oilfield Thermal EPTT Plant need to dynamically adjust the EPTT era in accordance to the load of the EPTT grid and market place demand, and carry out the transformation of the frequency converter and the suction enthusiast. The motor was at first a 1600KW, 730RPM non-frequency variable pace motor matched by HangEPT EPT Factory. The speed manage mode soon after modifying the frequency is handbook management. Press the button velocity to increase 10RPM or drop 10RPM. The coupling is even now the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is regularly damaged, which right affects the standard EPTT era.

It is located through examination that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation procedure (the diameter of the admirer impeller is 3.3 meters) and is cut off, which has fantastic injury to the motor and the supporter.

Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent variety: ZL.99246247.nine). After one hour of destructive experiment and a lot more than a single 12 months of procedure examination, the gear is working quite properly, and there is no Change the diaphragm. twelve units have been rebuilt and the procedure is in very good condition.
