Edit this paragraph maintenance
Because the hydraulic cylinder to be under great pressure, heavier the load, the greater the pressure there, so do the hydraulic cylinder maintenance work is a whole hydraulic system designed to protect the most important part.
Hydraulic system of hydraulic cylinder is equivalent to the heart, heart problems it is difficult to fix, so maintenance of the hydraulic cylinder is to be careful.
First of all, to rust. Because the hydraulic cylinder part is in the working condition of the piston out of the cylinder, naturally, would be eroded by oxides, acid gas, which we need to give it the coating protects the right amount of grease to avoid erosion and as a load-bearing part of the piston break can occur at work.
