Shandong Heqi Hydraulic Machinery Equipment Co., Ltd

 

The Type BMM hydraulic motor is an advanced hydraulic transmission element with the latest dynamic seal design and excellent high back pressure carrying capacity. This kind of motor is widely used in construction machinery, agricultural machinery, ships, petroleum equipment, mining machinery and other fields. The following is a detailed introduction of the BMM hydraulic motor.

 

First of all, the latest dynamic seal design of the BMM hydraulic motor is excellent, which ensures that it does not leak hydraulic oil during operation, thus ensuring the normal operation of the system. At the same time, this dynamic seal design can also extend the service life of the hydraulic motor and reduce maintenance costs, which brings great convenience and economic benefits to the user.

 

Secondly, the BMM type hydraulic motor also has a very high back pressure carrying capacity, which is one of its excellent performance. In some special applications, the back pressure may be very high, at this time if the use of general hydraulic motors, it is difficult to ensure its normal operation. The BMM hydraulic motor can easily cope with high back pressure, even in extreme conditions can work normally, its reliability and stability is very good.

 

In addition, the BMM hydraulic motor also has a high speed range and output torque, which can meet the needs of different applications. For example, in construction machinery and agricultural machinery, BMM hydraulic motors can be widely used in different power transmission systems such as lifting, expansion and rotation. In Marine and mining machinery, BMM hydraulic motors can also be used in a range of different work situations such as propulsion, hydraulic grasping and lifting.

 

Finally, the operation of the BMM hydraulic motor is very simple, and the user can achieve the ideal working effect by adjusting the flow control valve or the acceleration and deceleration valve. At the same time, if there is a problem during use, the BMM hydraulic motor can also be quickly restored through simple maintenance and repair. These have brought great convenience and convenience to users.

 

In general, in the field of hydraulic transmission, the BMM type hydraulic motor is a very excellent product, with advanced dynamic seal design and high back pressure bearing capacity, to meet the needs of various applications. At the same time, its operation is simple, easy to maintain, users can easily grasp and use. We believe that in the near future, the BMM hydraulic motor will occupy a more important position in the hydraulic transmission market.

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 The series motor adopt special imported shaft seal assembly. 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. 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.
