A hydraulic press is a machine that uses hydrostatic pressure to process various materials. The hydraulic press is generally composed of the machine (host), power system and hydraulic control system. The following editor of MCC will talk about the damage caused by water in the hydraulic system of the hydraulic press. The damage caused by water in the hydraulic system includes:
1. The damage of water to the hydraulic system can react with hydraulic oil, forming acid, gum and sludge, and water can also precipitate additives in the oil;
2. The main effect of water is to reduce the lubricity, the micro-dissolved in the hydraulic oil can react with the hydraulic oil to form acid, colloid and sludge, and the water can also precipitate the additives in the oil;
3. The main effect of water is to reduce the lubricity of the hydraulic machine. The trace amount of water dissolved in the hydraulic oil can accelerate the wear of high-stress parts. Bearing life has dropped by 30% to 70%. Water can cause adhesion of the control valve, causing cavitation damage at the pump inlet or other low-pressure parts; corrosion and corrosion of metals.
