Application Case

Standard circumstance of diaphragm coupling used to variable frequency speed control products

JMB type coupling is used to Daqing Oilfield Thermal Energy Plant

According to the requirements of Daqing Electric Power Corporation, Daqing Oilfield Thermal Energy Plant must dynamically adjust the power technology in accordance to the load of the energy grid and industry 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 velocity motor matched by Shenyang Motor Factory. The velocity handle manner following modifying the frequency is handbook management. Press the button pace to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is usually destroyed, which right affects the typical electrical power era.

It is discovered by way of evaluation that in the approach of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the velocity regulation method (the diameter of the enthusiast impeller is 3.3 meters) and is minimize off, which has excellent injury to the motor and the enthusiast.

Later, they switched to the JMB460 double-diaphragm wheel-kind coupling of our manufacturing facility (patent variety: ZL.99246247.9). Right after one hour of damaging experiment and more than 1 calendar year of operation test, the products is running quite effectively, and there is no Replace the diaphragm. 12 models have been rebuilt and the operation is in excellent situation.
