Hydraulic oil water separator hydraulic machinery, construction machinery will use hydraulic oil, if the water, air, dust, solid particles pollution will cause the performance of hydraulic oil cracking, after cracking, the hydraulic oil not only causes the loss of additives, failure and basic oxidation, but also causes the safe operation of hydraulic system. 1. The main features of Hydraulic oil-water separator: 1 High filtering precision, strong ability of filtering impurities Bangjie ZJD series multi-functional hydraulic oil-water separator adopts multi-stage cylinder filter, the front stage with magnetic filter has strong ability of filtering impurities, the coarse filter uses high flow cleanable filter core, high filtering efficiency, can remove a lot of impurities in the oil, "glass fiber" high-efficiency precision filter device, large scale capacity, high strength, long life, can remove fine particles in the oil. Zjd Series Hydraulic oil-water separator adopts Special Polymer demulsifying device, which can separate liquid water and free water from oil quickly and easily, and also can remove dissolved water from oil. It can make the highly emulsified hydraulic oil become clear and transparent, and meet the requirement of hydraulic lubrication equipment. The hydraulic oil-water separator adopts pure physical filtration method, which does not change the original performance of the filtered oil. Can only be separated by the water pollution of hydraulic oil, impurities, harmful gases. Hydraulic oil vacuum oil filter, according to the different principles of the boiling point of water and oil and design, the utility model is composed of a vacuum heater, a coarse filter, a fine filter, a condenser, a vacuum separation tank, a vacuum pump, an oil discharge pump and an electric cabinet. The vacuum pump draws the air out of the vacuum tank to form a vacuum. The external oil, under the action of atmospheric pressure, passes through the inlet pipe into the primary filter to remove the larger particles, and then enters the heater, oil heated at 40 ~ 60 °C is passed through an automatic oil level control valve, which automatically controls the balance of oil entering and leaving the vacuum tank. The heated oil is separated into a semi-mist form by the jet wing rotating rapidly. The water in the oil rapidly evaporates into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then released back into the original water. After separation, the oil is discharged by the pump into the fine filter to filter out the particulate impurities, thus completing the whole process of rapid removal of impurities, water and gas in the oil by the vacuum filter.
