inlet adjusting to realize the adjustment of speed, with advantages of on-load startup

YOTZJ700/750 series speed-adjustable hydraulic coupling gear reducer

Product usage: match with 190 series diesel engines and electric motors produced by us. This series products

can be used in single pumping set of mud pump, also are suitable for traditional device of mechanical drilling rig.

Features: the product features the combination of fixed tubes and inlet adjusting to realize the adjustment of speed, with advantages of on-load startup, overload protection, torsional vibration isolation, impact mitigation, stepless speed regulation, quick and no-impact clutch, etc. The product is the best speed-adjustable transmission device for “replace oil by electricity” reformation of the main drive system of mud pump and drilling rig.
