How to solve the problem of hydraulic piston rod out of oil?

     During the use of hydraulic piston rods, there are times when it is clearly established that the piston rod was good at the time of assembly and that there are no marks on the surface. But after a period of use, it is found that the piston rod with oil. In fact, the piston rod with oil is a phenomenon often encountered in the use of the process, because in the use of the time, there will inevitably be some collision occurs, so it leads to the emergence of the phenomenon of oil. The appearance of its oil will affect the work to a certain extent, so how should we solve the problem of piston rod with oil?

Piston rod out of oil cause analysis:

　　1, the piston rod deformation;

　　2、The inner lip of the piston rod seal and the surface of the piston rod are not fitted.

　　3、The surface coating of the piston rod has been damaged during use, resulting in a bump on the surface.

　　4, The surface has scratches or in the process of use, accidentally knocked or bruised.

　　5, the cylinder head in the piston rod or guide the sealing groove size does not meet the requirements, so that the compression does not go up. And compression does not go, will slowly make the compression will become smaller, and finally lead to the piston rod out of oil.

　　Therefore, if you want to effectively solve the problem of piston rod out of oil, you need to check according to the above reasons. If in the process of use, found that the seals there will always have oil leakage problems, then it is generally because the inner lip of the seal and the piston rod surface does not fit. If you want to solve the problem, you must let the pressure oil smoothly into the inner lip, and then a pressure oil to press the inner lip, for example, by opening a channel in the guide sleeve, the pressure oil and the inner lip of the gap connected together.
