What is the reason for the leakage of the piston rod in the hydraulic cylinder?
1. The first reason is the unreasonable structure of the combined seal for the shaft.
2. The second important reason is that the gap between the piston rod and the guide sleeve in the hydraulic cylinder is no longer within a reasonable range. For example, the black surface of the piston rod encountered by many users is actually caused by this reason. From market surveys, we found that this factor accounts for a large proportion of the reasons for piston rod leakage, which has exceeded 60%. Therefore, everyone should pay more attention to this issue in the future.
3. The last factor is the leakage problem caused by damage to the piston rod surface. This is because in practical applications, many situations may cause certain damage to the surface of the piston rod, which will increase the friction between the seal ring and the piston rod early and cause the seal ring to wear and fail. This situation is one of the main reasons leading to the early leakage of the piston rod.
