1.Hydraulic cylinderDaily inspection content

① Leakage of hydraulic cylinder.

②Whether the operating state of the hydraulic cylinder is normal.

③Are there any abnormalities in the sound and temperature of the hydraulic cylinder during operation?

④ Whether the piston rod has scratches and contaminants sticking to it.

⑤The state of the installation part of the hydraulic cylinder, whether there is any looseness, cracks, seizure, deformation, etc.

2. Maintenance of hydraulic cylinder

① In addition to daily inspections, the connecting screws should be tightened regularly.

② Regularly replace the seals according to the specific working conditions of the hydraulic equipment.

③Pay attention to the cleanliness of the working medium.

④ Frequently monitor and pay attention to the working conditions of the hydraulic cylinder, observe the working pressure, speed, crawling and vibration.

⑤Keep the hydraulic cylinder clean to prevent dust, lint, dirt, etc. from entering the system.

3. Hydraulic cylinder repair

① If there are scratches on the surface of the piston rod, causing external leakage, the piston rod should be repaired.

② If there is serious corrosion on the surface of the piston rod, or the chromium plating layer on the surface within the working length of the piston rod is severely peeled off, it can be ground first, and then chrome-plated repair.

③When the dust-proof sealing ring on the piston rod is no longer dustproof, and dust, chips, sand, etc. enter the hydraulic cylinder and damage the surface of the piston rod, the seal should be replaced.

④ When the bending deformation value of the piston rod is greater than 20% of the design specified value, it must be corrected and repaired.

⑤ When the leakage in the hydraulic cylinder exceeds 3 times of the designed value, the cause of the leakage should be checked.If the seal fails, the seal should be replaced; if the gap is too large after the piston is worn, the piston should be redone and repaired.

⑥ Check if there is leakage at both ends of the hydraulic cylinder.If the seal at the end cover is aging or damaged, the seal should be replaced; if the connecting screw is loose, it should be tightened.

⑦ When the cushioning effect of the cushioning hydraulic cylinder is not good, the cushioning device must be inspected and repaired.
