QJM series hydraulic motor can constitute hydraulic transmission device with different oil pumps, valves and hydraulic parts, which can meet the requirements on all conditions. QJM hydraulic motor has the characteristics of light weight, small volume, wide speed regulation range, perfect stablity performance at low speed, tolerance of stamping, high efficiency, long lifetime, etc. Now it is widely used in constructional engineering, metallurgical equipment, petroleum, coal mine, ship, geological prospecting, etc.
Main features:
1. Because the rolling body of this motor is replaces by a steel ball rather than two or more rollers and beams. Therefore, QJM series hydraulic motor has such features as: simple structure, reliable performance, small volume and light weight.
2. Small kinematics' pair inertia and hard steel ball make this motor continuously work under the strong impact load.
3. QJM series hydraulic motor has higher mechanical and volumetric efficiency. It can operate stably at low speed, and it has large starting torque.
4. Because of the characteristics of the structure, this motor's requirement of oil return backpressure is lower, general need is 0.3-0.8Mpa, the higher the speed, the greater the backpressure.
5. As this model has variable displacements dual and trinal speeds, it has greater speed range.
6. Simple structure and easy maintenance. It has no special requirement for the cleanliness of the oil. And the oil filtration precision can be selected according to the requirement of the matching oil pump.
