Specifications

 

BM1 series orbital hydraulic motor have an integrated body made of output shaft and spool valve, stator-rotor assemble of toothed shape

Main function features

1. Shaft distributes flow, simple and compact structure, high accuracy of flow distributing

2. Stator-rotor of toothed shape, high mechanical efficiency, longer working lifetime under high pressure

3. Touching-ball bearing of coupled-angle, bear higher loading in both radial and axial directions, small friction force, high mechanical efficiency.

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 °C.

5. The maximum allowable back pressure is 10MPa, but the recommended back pressure should not exceed 5MPa.a leaking 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.
