For the hydraulic system, the hydraulic cylinder is like the heart, the bottom flange engineering hydraulic cylinder if the heart is difficult to repair, so the maintenance of its need to be careful. First in the maintenance period to pay attention to do a good job of rust. This is because the piston part in the working state is to extend the cylinder, will naturally be oxide, acid gas erosion, which requires us to coat it with appropriate grease protection, lest as a bearing part of the piston erosion and may break in the work.

In the process of use also need to do a good job of its maintenance and cleaning. At the same time, pay attention to the selection of suitable hydraulic oil and oil seal, hydraulic cylinder of different hydraulic oil choose different materials of oil seal, to ensure the life of the hydraulic cylinder. The heavier the load, the greater the pressure that the cylinder has to bear. So the maintenance of the oil cylinder is an important part of the maintenance of the entire hydraulic system.

First of all, a very important aspect is the need for regular cleaning to ensure its cleanliness. For example, when we regularly clean the power unit of the hydraulic cylinder, what should we pay attention to during the cleaning? First, we can heat the cleaning oil to the proper temperature, which can effectively remove the residue from the equipment.

Of course, after the cleaning work is completed, there are some follow-up work to deal with, which is an important means to ensure the performance of the hydraulic cylinder. The important thing is to prevent corrosion and other undesirable problems, we should continue to operate the equipment for a while, until the temperature returns to normal, and pay attention to the oil used in cleaning should be eliminated.

We can also use other methods to clean, to ensure the effectiveness of cleaning. Farm hydraulic cylinders, for example, can be used about every 10 minutes if the system in which the cylinder is located is operated intermittently. In addition, it can also be installed when the machine is shut down, so as to achieve more ideal results.
