How to Quickly Solve the Leakage of Piston Rod Seal

When we use hydraulic cylinders, the seal failure of the piston rod is often caused by the seal failure of the guide rod, which eventually leads to the seal leakage of the piston rod. When this kind of bad phenomenon occurs, under normal circumstances, it is caused by the movement of the load in the direction and the misalignment of the hydraulic cylinder. So is there any way to effectively solve this kind of failure?
Common piston rod failure phenomena:
1. If it is a piston rod with a relatively long stroke, or a hydraulic cylinder with a relatively small diameter, it is basically caused by insufficient rigidity, which causes the piston rod to drop easily in thrust, and the deformation of the deflection occurs. It will affect the lateral force of the guide sleeve, and serious leakage will eventually occur.
2. However, if the hydraulic cylinder is guaranteed to be under load and used as a linear reciprocating operating mechanism, then the piston rod and the seal will definitely appear eccentric on the guide sleeve, and the guide sleeve will also appear sideways. Due to the high load, the sealed guide sleeve has serious wear on the surface, thus causing damage to the seal and causing leakage failure.
Ways to effectively solve the piston rod failure:
1. To ensure the straightness of the piston rod, when we start processing it, we need to pay attention to the processing dimensions between the piston rod and the piston, the coaxiality and the sealing groove;
2. When installing the piston rod, avoid the axis line of the hydraulic cylinder and the deviation of the running direction of the load;
3. Under normal circumstances, the sealing guide sleeve will directly determine the load on the material, so the hardness requirement will be relatively high, and it is required to use a material with a relatively strong bearing capacity. In the case of damage to the piston rod, it should also be Choose a harder material.
