BM6 series orbital hydraulic motor is a kind of advanced plane distribution structure of hydraulic motor, the series of motor using the insert column rotating stator pair, with high working pressure, high efficiency, high efficiency and good retention, long working life characteristics. 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.

• Advanced plane flow distribution structure, so that the motor with high precision, wear after the automatic compensation function is strong, to ensure high volumetric efficiency, motor long life, to ensure that the motor speed is stable, smooth load speed characteristics. It can withstand high working pressure and large output torque.

• Advanced rotary shaft seal design to withstand high back pressure capacity.

• Tapered roller bearing structure, bearing shaft, radial load capacity, the motor can directly drive the working mechanism, a wide range of applications.

Main technical parameters

* 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.
