How to deal with external leakage of axial piston motor?

2025-04-28

External leakage is common in the following areas: Leakage at the shaft seal is mostly due to aging of the seal or wear on the shaft surface. The seal needs to be replaced and the roughness of the shaft surface needs to be checked, and repaired if necessary. Leakage at the housing joint surface may be caused by loose bolts or damaged gaskets. The bolts should be tightened or the gaskets should be replaced according to the specified torque. Leakage at the oil port connection is usually caused by loose joints or damaged sealing rings, which need to be re-tightened or replaced. It is worth noting that excessive internal leakage will increase the pressure at the shaft seal and cause seal failure. Therefore, when dealing with external leakage, the internal wear should be checked at the same time. For motors that are activated after long-term disuse, the sealing material may lose its elasticity due to oil loss and hardening. The sealing status should be checked before starting.
