Application Case

Common situation of diaphragm coupling utilized to variable frequency speed management tools

JMB variety coupling is utilized to Daqing Oilfield Thermal Power Plant

According to the requirements of Daqing Electrical Electrical power Company, Daqing Oilfield Thermal Electrical power Plant need to dynamically adjust the power generation in accordance to the load of the electricity grid and market desire, and carry out the transformation of the frequency converter and the suction fan. The motor was at first a 1600KW, 730RPM non-frequency variable speed motor matched by Shenyang Motor Manufacturing facility. The speed manage mode soon after shifting the frequency is handbook manage. Push the button speed to enhance 10RPM or drop 10RPM. The coupling is nevertheless the authentic elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is often damaged, which straight impacts the standard electricity technology.

It is found by way of examination that in the method of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the velocity regulation approach (the diameter of the supporter impeller is three.3 meters) and is reduce off, which has fantastic injury to the motor and the fan.

Later, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing unit (patent number: ZL.99246247.9). Soon after 1 hour of harmful experiment and far more than one 12 months of procedure examination, the products is working really well, and there is no Substitute the diaphragm. twelve models have been rebuilt and the procedure is in excellent problem.

Application Case

Standard case of diaphragm coupling utilized to variable frequency speed manage products

JMB variety coupling is utilized to Daqing Oilfield Thermal Energy Plant

According to the requirements of Daqing Electrical Electricity Corporation, Daqing Oilfield Thermal Electricity Plant should dynamically modify the electrical power era in accordance to the load of the electricity grid and industry demand from customers, and carry out the transformation of the frequency converter and the suction supporter. The motor was at first a 1600KW, 730RPM non-frequency variable pace motor matched by Shenyang Motor Manufacturing unit. The speed manage manner following altering the frequency is guide control. Press the button speed to improve 10RPM or drop 10RPM. The coupling is nevertheless the original elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is usually destroyed, which directly affects the normal energy generation.

It is found via analysis that in the procedure of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the admirer impeller is three.3 meters) and is reduce off, which has excellent injury to the motor and the supporter.

Afterwards, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing facility (patent variety: ZL.99246247.nine). Right after 1 hour of destructive experiment and far more than one particular 12 months of operation examination, the tools is working really nicely, and there is no Exchange the diaphragm. 12 units have been rebuilt and the operation is in good situation.
