With advantages of on-load startup,overload protection,torsional vibration isolation,impact mitigation,stepless speed regulation
YOTFJ450/560/650/750/875 speed-adjustable hydraulic coupling reverse-gear reducer
Product usage: used together with 140, 190, 260, 320 and other series diesel engines manufactured by us and Caterpillar, Volvo and Cummins diesel engines or electric motors for driving mud pumps.
Features: the product features the combination of fixed tubes for oil drain and imported valve control and regulation to realize the adjustment of speed. With advantages of on-load startup, overload protection, torsional vibration isolation, impact mitigation, stepless speed regulation, quick and steady clutch, etc, the product is the best variable speed drive for mud pump.
Technical data:
Input speed: 1000~1500 r/min
Transmission power: 200~3000 kW
Rated efficiency: ≥96%
Gear reduction ratio: 2.0~3.3 (depending on the equipments used by the customer)
Rated slip: 3%
