Classification:
Description
BM5 series orbital hydraulic motor is a kind of plane flow distribution structure hydraulic motor, using column-mounted rotating stator pair, which has the characteristics of high working pressure, high working efficiency, good efficiency retention and long working life. On the basis of standard structure, multi-functional variant design can be carried out according to user requirements. Its characteristics:
• The use of advanced stator parameter design, low starting pressure, high efficiency and good retention.
• Tapered roller bearing structure, bearing shaft, radial load capacity, so that the motor can directly drive the working mechanism, expand the scope of use.
• Advanced plane flow distribution structure, so that the motor with high precision, automatic compensation ability after wear, to ensure high volumetric efficiency, motor long life, to ensure that the motor speed is stable, smooth load speed characteristics.

* Continuous value refers to the maximum value that the displacement motor can work continuously.
* The intermittent value refers to the maximum value of the displacement motor working for 6 seconds in 1 minute.
* The peak value refers to the maximum value of the displacement motor working for 0.6 seconds in 1 minute.
◎ Recommended oil: anti-wear hydraulic oil, viscosity 37 ~ 73cSt, oil cleanliness IS018/13, the highest working oil temperature 82 ℃.
◎ Special dynamic seal design, the back pressure allowed by the motor can reach 7 ~ 20MPa (optional), but in order to obtain good service life and comprehensive performance, it is recommended to use the back pressure not to exceed 5MPa. When exceeding the limit, it is recommended to connect the external leakage oil pipe. When connecting the external leakage pipe, it should be ensured that the motor can always be filled with oil. The drain pipe should have a certain throttle to keep the back pressure above 3.5Bar. In addition to maintaining a low back pressure, the external drain pipe can also take away the wear and pollution generated in the motor, and can produce a certain cooling effect.
◎ The motor should have a running-in period before full load work, and it is recommended to run in less than 30% of the maximum working pressure for 1 hour. The maximum output torque of the motor is related to the selected shaft type.
