YOTZJ700/750 Hydraulic Coupling Speed Reducer

YOTZJ700/750 Hydraulic Coupling Speed Reducer

The hydraulic coupling speed reducer matches with our 190 series diesel engines, and electric motors. It is not only suitable for a single unit of slush pumps, but also applicable to the traditional mechanical drilling rigs.

The hydraulic coupling speed reducer uses the combination of fixed tube and inlet regulating to realize adjustment of speed. It provides the advantages of on-load starting, overload protection, isolation of torsional vibration, impact mitigation, stepless speed regulation, quick and no-impact clutch, and more. This product is an optimum speed-adjustable transmission device for "replace oil by electricity" reformation for the main drive system of mud pumps and drilling rigs.

Technical Indicators
Input speed: 1000~1500 r/min
Transmitted power: 600~1200 kW
Rated efficiency: ≥96%
Range of speed regulation: 1~1/3

DO Series Power Units of Electric Motor Coupling

YOTZJ700/750 Hydraulic Coupling Speed Reducer

The DO series power units of electric motor coupling are newly developed products to realize electric drive reformation of traditional mechanical drilling rigs, reduced drilling cost, and improved economic benefits. Driven by high-power motor, the power unit allows users to make full use of low-cost network power supply to reduce drilling cost by 30%~45%. The product is especially suitable for regions with long drilling period, complicated geological conditions, inaccessible transportation, and concentrated wellsites. In addition to advantages of on-load starting, overload protection, isolation of torsional vibration, impact mitigation, stepless speed regulation, quick and no-impact clutch, etc., the power unit has low failure rate, good performance, easy operation and maintenance, safety, no exhaust emission and can effectively reduce noise and enhance working environment. It has positive and profound influence in green drilling.
