The disassembly of the waste paper baler hydraulic cylinder requires professional operation. After the disassembly, the price of the straw baler should first check the appearance of each part of the hydraulic cylinder. According to experience, it can be judged which parts can continue to be used and which parts must be replaced and repaired.

1. The inner surface of the cylinder. The inner surface of the waste paper baler cylinder has a very shallow line-like frictional injury or a point-like flaw, which is allowed, and it is useless.

If there is a vertical strain, even if a new piston seal is replaced, it is impossible to prevent oil leakage. The inner hole must be ground, or it can be corrected with fine sandpaper or oil stone. When the longitudinal strain is deep and cannot be corrected, the new cylinder must be replaced.

2. The sliding surface of the piston rod. When a longitudinal strain or a scratch occurs on the sliding surface of the piston rod that slides relative to the sealer piston rod sealing ring, the judgment and treatment method are the same as the inner surface of the cylinder. However, the sliding surface of the piston rod is generally hard chrome plated. If a part of the plating layer is peeled off due to wear and a longitudinal flaw is formed, the oil leakage at the piston rod seal has a great influence on the operation. The old coating must be removed, rechromed and polished. The chrome plating thickness is about 0.05mm.

3. Sealed. Piston seals and piston rod seals are key components to prevent oil leakage inside the waste paper baler hydraulic cylinder.

When inspecting the seal, first observe the damage of the lip of the seal and the wear of the seal friction surface. When it is found that there is a slight scratch on the lip of the seal and the friction surface is slightly worn, it is better to replace it with a new one. Seals that have been used for a long time and whose materials are hardened and brittle must also be replaced.
