Hydraulic motor is one of the core components in hydraulic transmission system, widely used in various fields such as engineering machinery, agricultural machinery, mining machinery, etc. By proper maintenance, the normal operation of hydraulic motors can be ensured, their service life can be extended, and work efficiency can be improved. This article will share in detail the maintenance cycle of hydraulic motors.

1、 Preparation work before maintenance of hydraulic motor

1. Confirm the brand, model, specifications, and other basic information of the hydraulic motor, and search for the corresponding maintenance manual or technical data.

2. Perform system troubleshooting on the hydraulic system to ensure its normal operation.

3. Determine the working environment after the hydraulic motor stops operating to ensure safe maintenance.

2、 Maintenance cycle of hydraulic motor

1. Interface cleaning: During the operation of hydraulic motors, they may be contaminated by dust, oil, and other pollutants. Therefore, regularly clean its interior. It is recommended to do it once every month.

2. Oil replacement: The lubrication performance of the oil inside the hydraulic motor will affect its working efficiency and service life. Therefore, it is recommended to replace the oil every 6 months or after 4000 hours of use.

3. Seal inspection: The seals inside the hydraulic motor may be damaged or aged due to their service life, collisions, and other reasons, leading to hydraulic leakage. Therefore, it is recommended to check the seals every quarter and replace them promptly.

4. Inspection of rotors and gears: Rotors and gears are key components of hydraulic motors, and their operating conditions should be regularly checked and replaced or repaired accordingly. It is recommended to conduct an inspection every 9-12 months.

5. Direct observation: If abnormal noise, temperature, or other abnormal situations are found during the operation of the hydraulic motor, the machine should be stopped in a timely manner for inspection, repair, or replacement of problematic components.

3、 Other precautions

1. Pay attention to safety during maintenance to avoid injury to people caused by hydraulic motors during operation.

When changing the oil, the selection should be based on factors such as the model of the hydraulic motor, working environment, and season.

During the use of hydraulic motors, attention should be paid to maintaining the oil level to prevent damage to the hydraulic motor or accidents caused by insufficient liquid level during operation.

4. Regularly inspect and replace auxiliary components of hydraulic motors, such as oil pipes, joints, rubber pads, etc.

In summary, the maintenance cycle of hydraulic motors is a very important link. Following the prescribed cycle for maintenance can ensure the normal operation of hydraulic motors and extend their service life. I hope that consumers and manufacturers can pay more attention to the maintenance of hydraulic motors and jointly promote the healthy development of the hydraulic motor industry.
