If the rebound hydraulic cylinder needs to fully meet the user's requirements, in addition to design experience and processing accuracy, it is also necessary to use it properly and maintain it regularly. The gas cylinder should be deflated before use, the buffer adjustment valve should be adjusted to a reasonable position, the cleanliness of the oil should be regularly checked, and the dust on the oil cylinder should be regularly cleaned. In addition, pay attention to waterproof and fire prevention. 1 Inspection and maintenance of seals Piston seal is the main component to prevent the leakage of rebound hydraulic cylinder. For lip seals, it is important to check the lip for damage and wear.
For combination seals, check the wear of the sealing surface, and then determine whether the seal is usable. In addition, the static seal ring between the piston and the piston rod should be checked for crushing. The piston rod seal should focus on checking the wear of the seals and the support ring. Once the seal and the guide support ring are found to be defective, the seal should be replaced with the same structure and suitable material according to the structural form of the repaired hydraulic cylinder seal. This can minimize the difference between the seal and the sealing surface The thickness of the oil film reduces the leakage of the seal.
