Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy, and the hydraulic cylinder is indispensable for normal operation and use, so the use of oil is very important. However, it should be noted that before starting, check the oil level and check whether the switch of each oil circuit is in the correct standby state.

The hydraulic cylinder can not drive the load when working, mainly manifested as the piston rod stop is not allowed, insufficient thrust, speed decline, unstable work, etc., the reasons are:

Engineering hydraulic cylinder traditional repair method is to disassemble the damaged parts after outsourcing repair, or brush plating or the surface of the overall scraping and research, the repair cycle of the hydraulic cylinder block scratched repair long, high cost.
