1. The unqualified raw materials are used to replace the aluminum alloy or plug. The incorrect installation of the parts will lead to long-term load of the motor, and the coupling will not spray, which will burn the motor.

According to China trade remedy information network, on June 14, the United States International Trade Commission (USITC) voted to make a negative final ruling on anti-dumping and countervailing industrial damage of freight train coupler systems and components imported from China

The hydraulic coupling has the functions of flexible transmission, shock mitigation and torsional vibration isolation, which can prolong the starting time, reduce the starting current, enable the power machine to start with light load, solve the difficult problem of starting with heavy inertia load, and protect the prime mover from overload. And the product can achieve energy saving and power saving effect by reducing the motor base number. The variable speed hydraulic coupler has the function of stepless speed regulation, and the energy saving effect is remarkable when it is applied to fans and pumps.

The inner bearing of the coupling adopts a double sealing structure, which is not in contact with water and has independent lubrication measures, so the service life of the bearing is long
