Application Situation

Common circumstance of diaphragm coupling used to variable frequency pace control equipment

JMB type coupling is used to HangZhou Oilfield Thermal Energy Plant

According to the requirements of HangZhou EPT Power Company, HangZhou Oilfield Thermal Power Plant need to dynamically modify the electrical power generation according to the load of the electricity grid and market demand from customers, and carry out the transformation of the frequency converter and the suction enthusiast. The motor was initially a 1600KW, 730RPM non-frequency variable pace motor matched by HangZhou Motor Manufacturing unit. The velocity handle mode after altering the frequency is manual manage. Press the button pace to improve 10RPM or fall 10RPM. The coupling is even now the first elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is regularly damaged, which straight impacts the typical electrical power era.

It is identified by way of evaluation that in the approach of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the enthusiast impeller is 3.three meters) and is lower off, which has wonderful damage to the motor and the supporter.

Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our manufacturing unit (patent amount: ZL.99246247.nine). After one hour of harmful experiment and much more than one year of operation take a look at, the gear is running extremely effectively, and there is no Substitute the diaphragm. twelve models have been rebuilt and the procedure is in great issue.
