Merchandise demonstrate



one,CZPT-diaphragm and tiny axial opposite wheel type coupling is the patent product developed by our manufacturing facility,the patent No. ZL.99 two 46247.9

2,With compact strcture, the adjustment capacity,anti-inpact and vibration-absorbing and so forth properties will be higher by 35%-40% than these of single diaphragm opposite wheel kind.

3,Under unexpected diaphragm breakage conditions, the plum blossom form flange can nevertheless transfer the torque ,the safety house is very good .

Software Situation

Common case of diaphragm coupling applied to variable frequency speed management equipment

JMB type coupling is used to HangCZPT Oilfield Thermal Power Plant

According to the demands of HangCZPT CZPT Power CZPT, HangCZPT Oilfield Thermal Electrical power Plant must dynamically change the electricity era in accordance to the load of the power grid and industry need, and have out the transformation of the frequency converter and the suction supporter. The motor was at first a 1600KW, 730RPM non-frequency variable velocity motor matched by HangCZPT Motor Factory. The pace handle method following modifying the frequency is manual manage. Push the button pace to improve 10RPM or drop 10RPM. The coupling is still the unique elastic decoupling coupling, and the elastic de-coupling coupling soon after frequency conversion is regularly broken, which immediately impacts the typical electricity era.

It is found by way of examination that in the method of frequency conversion speed 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 harm to the motor and the fan.

Later, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing unit (patent amount: ZL.99246247.9). Soon after one hour of damaging experiment and a lot more than 1 12 months of procedure check, the equipment is operating really well, and there is no Exchange the diaphragm. 12 models have been rebuilt and the procedure is in good situation.
