Software Situation

Normal situation of diaphragm coupling utilized to variable frequency pace management equipment

JMB sort coupling is used to HangCZPT Oilfield Thermal Energy Plant

In accordance to the requirements of HangCZPT CZPT Electrical power CZPT, HangCZPT Oilfield Thermal Energy Plant should dynamically modify the power era in accordance to the load of the electricity grid and market place need, and carry out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable pace motor matched by HangCZPT Motor Factory. The pace handle mode soon after modifying the frequency is guide handle. Press the button speed to increase 10RPM or fall 10RPM. The coupling is even now the authentic elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is frequently destroyed, which directly impacts the typical power generation.

It is discovered by means of examination that in the approach of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the velocity regulation process (the diameter of the supporter impeller is 3.three meters) and is lower off, which has wonderful harm to the motor and the fan.

Later on, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing facility (patent quantity: ZL.99246247.nine). Following one hour of destructive experiment and far more than one year of procedure test, the equipment is working quite properly, and there is no Exchange the diaphragm. twelve models have been rebuilt and the procedure is in very good condition.
