Â
BMP hydraulic rail motor is a kind of high performance hydraulic motor, which is widely used in the power transmission system of various mechanical equipment. This motor uses a double rolling bearing design, has a greater lateral load capacity, can adapt to a variety of working conditions, and has a very good performance.
Â
In the design of BMP hydraulic rail motor, the advanced double rolling bearing technology is adopted, which makes this motor have higher load capacity, better stability and longer life than the traditional single rolling bearing motor. At the same time, it also uses high-quality materials and processes to ensure the efficiency, stability and reliability of the motor.
Â
The advantages of BMP hydraulic rail motors also include their wide applicability. Whether it is in agricultural machinery, construction machinery, industrial equipment or rail transit systems, this motor can play a very good performance. Due to its dual rolling bearing characteristics, it can also easily adapt to a variety of different workloads and working conditions, whether in harsh environments or high temperature, high pressure working conditions, can show excellent stability and reliability.
Â
In addition, the BMP hydraulic rail motor also has excellent efficiency and energy saving characteristics. The design and process allow the motor to operate with low noise and low coefficient of friction, which allows for higher energy efficiency and lower energy consumption. This has positive significance for improving work efficiency, reducing operating costs and protecting the environment.
Â
In short, BMP hydraulic rail motor is a very good hydraulic transmission equipment. Its double rolling bearing design, wide applicability, high efficiency and energy saving characteristics make it an ideal power choice for various mechanical equipment. It is believed that in the future industry and transportation fields, BMP hydraulic rail motors will continue to play an important role, bringing more convenience and benefits to people's production and life.

â—Ž The intermittent operating pressure refers to the Max. allowable operating pressure at the motor inlet port, and the continuous operating pressure refers to the pressure difference between the inlet port and the return port.
â—Ž Do not operate the motor at the Max. speed and the Max. pressure at the same time.
â—Ž The motor operating time per minute must not exceed 10% under intermittent operating conditions.
◎ Recommended oil: anti-wear hydraulic oil; Viscosity: 37-73cst; ​​Oil cleanliness: IS018/13.
◎ The Max. oil temperature should be 80℃.
â—Ž With special dynamic seal design, the Max. allowable back pressure of the motor can be up to 10MPa; however, in order to obtain the good service life and comprehensive mechanical performances, the back pressure should not exceed 5MPa. If it is exceeded, it is recommended to connect the external drain pipe; when connecting the external drain pipe, ensure that the motor is always filled with oil. The external drain pipe should be throttled at a certain degree, to maintain a back pressure of more than 3.5 Bar. When connecting the external drain pipe, in addition to maintaining a low back pressure, the wear contaminants generated inside the motor can be removed and a certain cooling effect can be achieved.
â—Ž There should be a running-in period before the motor is operated at full load. It is recommended to run for 1h at 30% of the Max. operating pressure.
