Hydraulic motor manufacturer analysis of cleaning motor oil circuit steps

In order to reduce the pressure energy loss of the hydraulic motor in the use of the hydraulic system, we should start from the inside and reduce the power loss while reducing the pressure loss in the system. To solve this problem, we can improve the pressure loss of the internal flow channel of the components, and adopt integrated circuit and casting runner. At the same time, it is necessary to reduce or eliminate the throttling loss of the system, reduce the non safety overflow as much as possible, and avoid using the throttling system to adjust the flow and pressure.

In the use of materials, can use static pressure technology manufacturing materials and new sealing materials, which can effectively reduce the friction loss. It is necessary to maintain the hydraulic motor in use. In order to prevent the pollution from affecting the service life and reliability of the motor, a new pollution detection method must be developed to measure the pollution on-line. It is necessary to adjust the pollution timely without delay, so as to avoid the loss caused by untimely treatment. In order to reduce the pressure energy loss of hydraulic motor, manufacturers and consumers need to work together to prevent the pressure energy loss to a greater extent. How to reduce the loss of hydraulic motor in use

Of course, the cleaning of the hydraulic motor is also very important. Hydraulic motors are usually washed before they are put into use. The purpose of flushing is to remove the pollutants, metal chips, fiber compounds, iron cores, etc. in the first two hours of operation, even if the motor is not completely damaged, it will cause a series of failures. Therefore, the following steps should be followed to clean the motor oil circuit:

1. Clean the oil tank with a dry cleaning solvent, and then remove the solvent residue with filtered air.

2. Clean all the pipelines of the motor. In some cases, it is necessary to impregnate the pipelines and joints.

3. The oil filter is installed in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.

4. A flushing plate is installed on the collector to replace the precision valve, such as electro-hydraulic servo valve.

5. Check whether all pipes are of proper size and correct connection.


Hydraulic motor

To achieve the above two points, we can basically reduce a certain loss in use, but we often encounter different problems when using the plunger hydraulic motor. Due to the special working conditions of the hydraulic motor, there are six special points to pay attention to when using it.

1、 When full load starting is required, attention should be paid to the starting torque of hydraulic motor. Because the starting torque of hydraulic motor is smaller than the rated torque, if ignored, the working mechanism will not work.

2、 Since the backpressure of the hydraulic motor is higher than the atmospheric pressure, the oil drain pipe of the motor should be led back to the oil tank separately and cannot be connected with the oil return pipe of the hydraulic motor. How to reduce the loss of hydraulic motor in use

3、 Because the hydraulic motor always has leakage, so close the inlet and outlet of the hydraulic motor to brake, it will still have a slow slip. When braking for a long time, a brake to prevent rotation shall be set separately.

4、 When the driven parts have large inertia (high rotational inertia or high rotational speed), if braking or running along the train in a short time is required, a safety valve (buffer valve) should be set in the oil return circuit to prevent damage caused by sharp hydraulic impact.

5、 When the hydraulic motor is used as the power part of the lifting or walking device, the speed limiting valve must be set to prevent the heavy objects from falling down quickly or speeding when the vehicle and other traveling mechanisms go downhill, which may cause serious accidents

6、 When using the quantitative motor, if you want to start and stop smoothly, you should use the necessary pressure control or flow control method in the circuit design.
