Industrial Small High Speed Hydraulic Motors BMM / OMM G 3/8’’For Mining
Mini Hydraulic Motors BMM / OMM G 3/8’’ High Speed In Mining , Sweepers , Harvesters
1. Features:
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 interoittent working conditions
4. The maximum working temperature is 80°.
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,viscosity37-73cSt,cleanliness ISO18/13.
