Hydraulic oscillating motor as one of the hydraulic system implementation components, in actual use is particularly important. But in the installation process should pay attention to what matters? The drive shaft of the hydraulic motor and other mechanical connection to ensure concentric, or use flexible connection. Please refer to the following steps for specific operation.

1, the hydraulic motor bearing capacity of radial force, for the motor can not withstand radial force, shall not be the pulley and other transmission parts directly mounted on the main shaft.

The active sprocket is driven by the hydraulic motor, and the passive sprocket drives the conveyor belt roller. According to the user, the motor often appears oil leakage phenomenon, the seal replacement less than 3 months to start leaking oil. What is the cause of oil leakage? The hydraulic motor through the chain drive to drive the pulley, due to the chain drive will also generate radial force, the oil seal with radial force after deformation, resulting in oil leakage.

2, hydraulic swing motor chain drive

① motor leakage oil pipe to be smooth, usually not connected to the back pressure, when the leakage oil pipe is too long or for some need to connect the back pressure, the size of which shall not exceed the value allowed by the low pressure seal.

② external leakage oil should be able to ensure that the motor's shell is full of oil, to prevent the shutdown of the shell all the oil flow back to the tank.

③ for a longer downtime of the motor, can not directly full load operation, should be airborne for a period of time before normal use.

3, the installation of swing motor frame to have sufficient rigidity

① install the motor bracket, the seat must have enough rigidity, to withstand the motor output torque when the role of the reaction force to it.

② the installation of the motor frame stiffness is not enough to produce vibration or deformation, and even accidents can not guarantee the drive and motor shaft between the concentricity of the coupling control within 0.1mm requirements.

4, hydraulic motor and gearbox should not be used together

① one of the characteristics of hydraulic transmission is the power to weight ratio, and in general, the hydraulic motor circuit itself can complete the usual speed regulation, variable speed function.

② If the hydraulic motor and then used together with gearboxes lose the characteristics of hydraulic control, but also make the volume and cost of equipment increased significantly.

5, hydraulic swing motor drainage port should be separate back to the oil tank

① Although from the general concept of all the return pressure is not high, but many hydraulic systems in the return oil still has a certain pressure, and the hydraulic motor drainage cavity is not allowed to have pressure.

② hydraulic motor drainage mouth of the internal is connected with the shell cavity, the shaft seal of the motor shaft only play a sealing role, not pressure resistance. If this port is connected with other return lines, it is easy to cause damage to the motor shaft seal, resulting in oil leakage, so do not allow the hydraulic motor drain port and other return lines connected together.

6, the hydraulic motor should not enter the air

① hydraulic system in the initial work, will inevitably contain air in the system pipeline.

② system commissioning is an important part of the system to exhaust the air, which is particularly important for the hydraulic motor.

③ hydraulic medium in the motor there is a sudden change from high pressure to low pressure process, and the process is very high frequency, on average, in about 10 times per revolution.

④When the hydraulic oil into the hydraulic swing motor contains air, it will produce local cavitation at the sudden change in pressure, so that the motor is quickly damaged.
