Periodic inspection and maintenance of hydraulic cylinders

As an important part of the hydraulic system, the stability and reliability of the performance of the hydraulic cylinder is directly related to the operational efficiency and safety of the entire system. Therefore, regular inspection and maintenance of hydraulic cylinders is very important.

In the inspection process, should focus on the following aspects:

1, sealing performance: check whether the hydraulic cylinder sealing device is intact, there is no leakage phenomenon. Seal wear and aging is the main cause of leakage, once found should be replaced in a timely manner.

2, fluid cleanliness: check whether the fluid in the hydraulic system is clean, free of impurities and contaminants. The cleanliness of the fluid has a direct impact on the performance and service life of the hydraulic cylinder. Hydraulic oil should be replaced regularly, and clean the oil tank and oil circuit.

3, cylinder and piston rod: check the cylinder cylinder wall and piston rod surface whether there are scratches, rust or wear. These damages will affect the sealing and movement accuracy of the hydraulic cylinder and should be repaired or replaced when needed.

4, connecting parts: check the hydraulic cylinder and the fastening of the connecting parts to ensure that there is no looseness. Looseness will lead to vibration and noise, and even cause safety accidents.

Through regular inspection and maintenance of hydraulic cylinders, you can find and solve problems in time to ensure the normal operation of the equipment and extend the service life.
