Product Description

Factory Supply Single Stage Vacuum Transformer Oil Purification Machine

Zy Single Stage Vacuum Transformer Oil Purification Machine

  1. This machine is applied to purify the unqualified transformer oil, mutual inductor oil,

switch oil and other insulation oil. 

Main Features

  1. With high vacuum pump. Vacuum degree can up to -0.098 Mpa.
  2. 3D flashing by vacuum, it can eliminate the liquid water quickly. And Use UK micro technology to remove the trace water and other dissolved water. The final oil water content can be <= 5ppm, gas content can be < 0.1%
  3. With Z type heater design, and the face of the heater is smooth, it can heating uniformity, avoid extra gas
  4. Three stages filters, it combines double FH trapezoidal network and high polymer material absorption technology, the particle’s precision can up to 5μ
  5. We use fluoric cushion not normal cushion, and double welding of the machine, with great sealing performance, can avoid extra gas and have longer life
  6. With automatically oil level control device

Working principle

  1.  When we turn on the machine, start to purify the oil, the oil will come into the primary filter

first by the vacuum negative pressure. To purify the bigger particles, normally 80μ      2.  After that oil will flow into the heater, then into the vacuum tank to dehydration and degassing by the vacuum      3. Then the oil flow through the second filter, normally 50μ
     4. Then the oil will flow into the fine filter, normally 5μ      5. Oil comes out or keep the loop working          


  1. After a certain period of running, the machine should be checked to see whether:
  2. The electrical control system is safe and reliable;
  3. The temperature controller is sensitive, reliable and accurate;
  4. Oil seals of the pump shaft are broken with leakage;
  5. There is any blockage with the running system and any abnormal noise with pumps or related motors;
  6. There is any air or oil leakage with the oil running system and at sealing joints.
  7. After each 3000 hours’ running, grease shall be replenished to prevent motors from being burnt.
  8. Special vacuum pump oil or lubricating oil N46 should be used fro the vacuum pump and oil replaced or replenished if necessary at any time.
  9. If the machine will not be used over 1 month, Place the machine in a dry environment with the panel door and all valves closed, and the machine proper protected by a covering.
