Hydraulic valve in the hydraulic oil mixed with water hazards

1. The way oil enters the water (1) The fuel tank cover due to alternating hot and cold and make the water in the air condense into water droplets fall into the oil. (2) The cooler or heat exchanger seal is damaged or the cooling tube ruptures causing the water to leak into the oil. (3) through the hydraulic cylinder piston rod seal is not tight into the system of moist air condensed into water droplets. (4) When the oil with human water and oil exposure to wet conditions and affinity with water absorption of water. 2. The oil mixed with water after the damage (1) mixed with a certain amount of oil in the water, the hydraulic oil emulsification was white cloud state. If the hydraulic oil itself has poor anti-emulsifying ability, the water can not be separated from the oil after being still for a while, leaving the oil in a cloudy state. This white turbid oil enters the interior of the hydraulic system, which not only rusts the internal components of the hydraulic valve, but also reduces its lubricity, aggravating the wear of parts and reducing the efficiency of the system. (2) After the iron-based metal in the hydraulic system is rusted, exfoliated rust flows in the hydraulic system pipes and hydraulic components and spreads and spreads, resulting in rusting of the entire system and more spalling of rust and oxides. (3) water and some additives in the oil produce precipitation and gum and other pollutants, accelerate the deterioration of oil. (4) Sulfur and chlorine in water and oil produce sulfuric acid and hydrochloric acid to exacerbate abrasion and abrasion of the components, and accelerate the oxidative deterioration of the oil and even generate a lot of sludge. (5) These water pollutants and oxidized products become catalysts for further oxidation, eventually leading to blockage or jamming of hydraulic components, malfunction of hydraulic valve system, clogging of distribution lines, reduction of cooler efficiency and clogging of oil filters Series of failures. (6) In addition, at low temperatures, the water condenses into tiny ice particles that also tend to clog the gaps and dead spaces in the control components. More Keyword Search: Hydraulic Valve
