Allowable Back Pressure 10MPa Motor Usage Guide
To ensure optimal operation of cycloid hydraulic motors such as OMM, OMP, OMR, BM3, BM4, the following is recommended:
1. Oil Temperature: Normal operating oil temperature is 20°C~60°C, maximum system operating temperature is 90°C (should not exceed one hour).
2. Filter and Oil Cleanliness Level: Filter filtration accuracy is 10-30 microns. It is best to add a magnetic block at the bottom of the oil tank to prevent metal shavings from entering the system. The solid contamination level of the working oil should not be higher than 19/16.
3. Oil Viscosity: The kinematic viscosity at an oil temperature of 40°C is 42-74 mm²/s. Hydraulic oil can be selected based on actual operating and ambient temperatures.
4. Motors can be used in series or parallel. When used in series or parallel, if the back pressure exceeds 10 MPa (speed below 200 RPM), an external drain port must be used for pressure relief. It is best to connect the external drain port directly to the oil tank.
5. The output shafts of BMS, BMSY, BMT, BMV, and BMK6 series motors can withstand significant axial and radial loads.
6. The optimal operating condition for the motor should be chosen between 1/3 and 2/3 of the rated operating condition.
7. To ensure a long service life for the motor, when applying a load, it should first run at 30% of the rated pressure for approximately 1 hour; in all cases, ensure the motor is filled with oil before applying a load.
