Software Scenario
Common case of diaphragm coupling used to variable frequency pace control products
JMB variety coupling is applied to HangCZPT Oilfield Thermal Electricity Plant
In accordance to the needs of HangCZPT CZPT Power CZPT, HangCZPT Oilfield Thermal Energy Plant should dynamically alter the power technology in accordance to the load of the electrical power grid and market place 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 HangCZPT Motor Manufacturing facility. The velocity control manner following shifting the frequency is guide handle. Push the button speed to improve 10RPM or fall 10RPM. The coupling is nevertheless the original elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is regularly ruined, which right affects the standard power era.
It is found via analysis that in the approach of frequency conversion pace regulation, the pin of the coupling can not bear the inertia of the velocity regulation method (the diameter of the admirer impeller is three.3 meters) and is lower off, which has fantastic injury to the motor and the admirer.
Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent quantity: ZL.99246247.nine). Right after one hour of destructive experiment and more than a single year of operation test, the tools is operating quite effectively, and there is no Substitute the diaphragm. twelve units have been rebuilt and the operation is in very good condition.
