Jichai brand YOTFJ650 speed-adjustable hydraulic coupling reverse-gear reducer

Product Description

The YOTJ650 series valve-regulated variable speed hydraulic coupling with new Bernard electric actuator could adjust the opening size of control valve by manual/remote control. The stable operation of actuator can be ensured by the functions of failure warning, auto phase correction, contact signal input/output, limit protection, hand-switch protection, etc. of actuator control system, which ensures the continuing adjustment and exact control of the control valve, so as to realize the stepless speed regulating of hydraulic coupling.

Application and Features

YOTJ650 series hydraulic coupling is characterized by load startup, torsional vibration isolation, buffering, stepless speed regulating, quick and stable clutching, etc. This series can totally replace the mechanical reducer box and international similar products with traditional configuration, improve the transmission quality of power unit, eliminate the shortcomings of traditional configuration completely, which is optimal power transmission equipment for power unit of gas drilling, refining, steel, coal, electric power enterprises, etc.

The combined use of diesel engine-hydraulic coupling reverse-gear box set and mud pump has the following advantages

1.The diesel engine coupling reverse-gear box is adopted to drive the mud pump. This fact eliminates the need for belt transmission, mechanical reducer and air bag clutch, and provides simplified transmission system, higher efficiency, reduced volume and weight and higher mobility.

2. The diesel engine and hydraulic coupling reverse-gear box are coupled via the high-elastic coupling, and are installed on a shared chassis with a combined high-pressure water cooling system. This feature simplifies the cooling system in the coupling and reduces auxiliary power consumption. The structure is compact and reliable.

3. Under drilling conditions, the mud pump driven by a diesel engine coupling reverse-gear box can reach different discharge capacities and pumping pressures controlled by adjusting diesel engine throttle or replacing cylinder sleeve or regulating opening of pneumatic control valve of coupling within limits in a stepless manner, so that the diesel engine can operate efficiently normally (≥1000r/min).

4.With functions of clutch, it is possible to apply the clutch when no impact and wearing appear.
