Good Quality BM4 hydraulic motor,slow speed motors widely used in Mining machine

Advantage:
1.Small, lightweight, smaller than other hydraulic motor of same torque
2.Wide speed range, non-grade adjustment of speed, minimum steady speed is 15rpm, easy and convenient to be equipped with, low cost
3.Used in series and in parallel way of a hydraulic system
4.little inetia of rotary, easily to be started, can rotate clockwise and counterclockwise, don’t stop rotating when change direction

Main function features:
1.Shaft groove distributes flow, simple and compact structure, high accuracy of flow distributing
2.Stator-rotor in toothed shape, high mechanical efficiency,longer working lifetime under high pressure
3.Touching-ball bearing of coupled-angle, can bear higher loading in radial and axial direction, low friction force, high mechanical efficiency

Main specification

Note: 

1. Intermittent means the entrance of the maximum pressure;continuous working pressure means the differential pressure.

2. Motor should not work under the highest pressure and the maximum speed.

3. The running time should not exceed 10% under intermittent working conditions.

4. The Maximum working temperature is 80°.

5. The Maximum allowable back pressure is 10 MPa,but the recommended back pressure should not exceed 5PM.a drain pipes is needed when exceeding.

6. One hour running time under 40% of maximum working pressure is recommended before full capacity working.

7. Recommending N68 anti-wear hydraulic oil,viscosity 37-73cSt,cleanliness ISO18/13.
