As the hydraulic cylinder to bear a large gas pressure, the heavier the load, it gas pressure will be more, therefore, to improve the automatic flow control valve hydraulic cylinder maintenance work is the maintenance of all hydraulic system is a vital part of the maintenance.
Hydraulic cylinder is equivalent to the cardiovascular of the hydraulic system, cardiovascular problems are difficult to repair, so the maintenance of hydraulic cylinders is to be careful and delicate.
First, to prevent rust treatment. Because the electro-hydraulic pressure control valve hydraulic cylinder piston rod part of the operating state is to extend the hydraulic cylinder, of course, will suffer from metal oxides, acidic gas erosion, which requires everyone to coat it with appropriate vegetable grease to carry out protection, to prevent the piston rod as a load-bearing components by erosion and may break at work.
Secondly, the oil should be removed and changed. Because of the long-term use, inevitably there are dirty things into the hydraulic cylinder, so in the use of pilot pressure control valve will produce friction to expand the situation, in addition, gear oil is a certain period of use, a long time without oil change will destroy or erode the internal structure of the hydraulic cylinder.
Cure than not to prevent, so in the operation of the hydraulic cylinder to manipulate the rate moderate, do not have to exceed 2m / s, so as to increase the use of the hydraulic cylinder period, in addition, in order to protect the organization and security, the internal structure of the assembly buffer device for the protection of the hydraulic cylinder is very reasonable.
