Common circumstance of diaphragm coupling applied to variable frequency pace manage equipment
JMB kind coupling is applied to Daqing Oilfield Thermal Electricity Plant
According to the specifications of Daqing Electrical Electricity Company, Daqing Oilfield Thermal Energy Plant must dynamically modify the electrical power era according to the load of the power grid and marketplace 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 pace motor matched by Shenyang Motor Manufacturing unit. The speed control method after modifying the frequency is guide control. Press the button velocity to enhance 10RPM or fall 10RPM. The coupling is even now the first elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is often ruined, which directly affects the regular electricity generation.
It is found by way of analysis that in the procedure of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the supporter impeller is 3.three meters) and is minimize off, which has excellent damage to the motor and the fan.
Later, they switched to the JMB460 double-diaphragm wheel-kind coupling of our manufacturing facility (patent amount: ZL.99246247.9). Following 1 hour of destructive experiment and more than one 12 months of procedure test, the products is running quite properly, and there is no Exchange the diaphragm. twelve models have been rebuilt and the procedure is in great condition.

Standard case of diaphragm coupling used to variable frequency velocity management gear
JMB sort coupling is applied to Daqing Oilfield Thermal Energy Plant
According to the specifications of Daqing Electric powered Electricity Company, Daqing Oilfield Thermal Electricity Plant ought to dynamically change the electrical power era according to the load of the energy grid and marketplace desire, and have out the transformation of the frequency converter and the suction admirer. The motor was at first a 1600KW, 730RPM non-frequency variable velocity motor matched by Shenyang Motor Manufacturing unit. The speed control mode right after altering the frequency is guide control. Push the button velocity to improve 10RPM or fall 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is often ruined, which straight impacts the regular power generation.
It is found by means of analysis that in the approach of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the pace regulation process (the diameter of the fan impeller is three.3 meters) and is cut off, which has wonderful damage to the motor and the supporter.
Later on, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing facility (patent number: ZL.99246247.nine). Soon after 1 hour of harmful experiment and much more than one 12 months of operation take a look at, the gear is running really well, and there is no Replace the diaphragm. twelve units have been rebuilt and the procedure is in very good condition.
