1800LPH Transformer Oil Purification Machine Working Principles

  1. When the transformer oil filtration plant is working, the waste transformer oil under the action of pressure difference inside and outside enters into the prefilter. The larger particles are filtered by the purifier and the oil is heated by multiple infrared rays before entering the special personalized vacuum separator. Waste transformer oil first evaporates into an oil mist in the vacuum separator and then forms a film. The contact area between the waste transformer oil and the transformer oil filter expands hundreds of times under the vacuum condition, and the water in the oil evaporates rapidly under the conditions of high heat, high vacuum, large surface, and high pumping speed and is discharged by the vacuum system.
  2. The steam discharged from the upper part of the vacuum separator is firstly cooled and dehumidified by the condenser and then cooled again in the cooler. The condensed water is discharged into the water storage device, and the air is finally discharged into the air by the vacuum pump after two condensations and dehumidification.
  3. The dry oil in the vacuum separator after vacuum vaporization and dehydration is raised from negative pressure to positive pressure through the oil pump. After secondary filtration, the clean oil is discharged from the oil outlet to complete the whole process of clean oil.
