High Vacuum Transformer Oil Filtration and Purification Equipment for Transformer Maintenance

After passing through the first stage coarse filter, the oil to be processed enters the heater for heating. The heated oil then passes through the second stage filter and enters the spiral spray atomization system. The insulating oil becomes a coarse mist and falls onto the reaction tower, entering the vacuum separation chamber. Moisture begins to evaporate, and the oil mist forms a three-dimensional, multi-layered evaporation structure inside the tank. Through short-term circulation, the purification purpose can be achieved. The oil products that have undergone impurity removal, dehydration, degassing, and acid removal are subjected to a precision filter under the action of an oil pump to complete a clean oil working cycle. The water vapor and hot air separated from the vacuum separation chamber enter the condenser, and most of the water vapor condenses into water and is stored in the water tank, discharged outside the machine. The hot air in the oil is cooled and discharged by the vacuum pump.
