The speed-adjustable hydraulic coupling gear reducer matches with our 140, 190, 260, 320 series diesel engines, Caterpillar, Volvo, Cummins diesel engines or electric motors to drive mud pumps.
The hydraulic coupling gear box uses the combination of fixed tube oil draining and inlet valve regulating to achieve adjustment of speed. With advantages of on-load starting, overload protection, torsional vibration isolation, vibration mitigation, stepless speed regulation, and quick and steady clutch, the gear reducer is an ideal choice for the variable speed drive of slush pumps.
Input speed: 1000~1500 r/min
Transmitted power: 200~3000 kW
Rated efficiency: ≥96%
Rated slip: 3%
Gear reduction ratio: 2.0~3.3 (according to customers' specific needs)
Range of speed regulation: 1~1/3
Clutch sensitivity: 6~8S
Our hydraulic coupling gear reducers are newly developed products for the mud solid control circulating system of mud pumps. The reducers use fixed tube speed regulating technology, providing stepless control of coupling speed and quick, steady clutch. They work perfectly with the mud pumps for oil drilling domestically.
The diesel engine hydraulic coupling gear box set (consisting of a hydraulic coupling gear reducer and a power machine) is a new type hydraulic transmission product specially designed by Jinan Diesel Engine Company Limited (JICHAI) in view of features of working conditions for the slush pump of oil drill. It is used to replace the diesel-driven single mud pump unit, eliminating traditional devices like mechanical reducer, airbag clutch, and drive belt. The diesel engine hydraulic coupling gear box set has compact structure, and is easy to operate and to maintain. With a wide power range of 105kW (140Hp)-3000kW (4000Hp), the product can completely meet the requirement for 200-2200Hp slush pump drive.
The power machine uses diesel engine or electric motor. Under circumstances of electric motor drive and full utilization of electric power resource from power grid, it can save energy cost by over 40%.
CNPC JICHAI was formed in 1920, we are a prestigious brand in China and is a global leader in internal conbustion engine and generator set manufacturing. Our power solutions are designed to improve your performance and productivity.
