Excavator hydraulic cylinder

After working for whole day excavator stops work, the hydraulic fluid  is in  high temperature, the air outside  is in low temperature, in outside fuel tank's hot air and fuel tank's cold air meet contact, coldly will condense the water-drop whereabouts in fuel tank's crown in the hydraulic fluid, gradually, in the hydraulic fluid will mix in the water. Subsequently evolves the acidification material dipping surface. In the mechanical operation and under the pipeline pressure impact's dual function, the metal pellet which the metal surface will fall off down will mix in the hydraulic fluid, if this time the hydraulic fluid will not make the cleaning treatment big metal pellet to filter by the filter element, but will be smaller than 10μm the pellet hydraulic pressure filter element cannot filter, will not be able to filter the attrition pellet mix will aggravate the metal surface in the hydraulic fluid the attrition once more, therefore the expert suggested that the hydraulic fluid filtration purification time will be 2000-2500 hours or 1 year purifies one time, when trade the fresh oil must purify one time. After the old oil purification in the system, changes the fresh oil,  replenishment with fresh oil, such residual old oil will not pollute the fresh oil.
The best measure, regularly purify the oil with the hydraulic fluid special-purpose vacuum oil filter machine, process the unnecessary moisture content and the mechanical impurity, and  maintains the cleanliness at NAS6-8 level, the moisture content in the GB code scope, the control oil quality is not easy to get older, like this unearths the equipment not to be easy to damage and the fat liquor is durable, help avoid losing and  waste!
