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

1.The dieselengine coupling reverse-gear box is adoptedto 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, Hot Selling variable speed reduction gearbox DH5B20E with motor it is possible to apply the clutch when no impact and wearing appear.
