Oil Dehydration Plants

OVERVIEW OF THE TRANSFORMER OIL DEHYDRATION PLANT

(1) The suction pump to draw oil from the electrical plant and deliver oil into the dehydration plant via a coarse strainer and flow indicator showing the movement of oil. Suction temperature indicator present.

 

  • Suction pump to be removed, checked and resealed on periodic cycles, approximately once every 18 months to 3 years of service defined by the end user.
  • Coarse strainer filter to be checked and cleaned prior to each time the plant is to be operated.
  • The rotation of the pump is specific to indicating the suction port of the suction pump. Top-port will equal suction port with clockwise rotation when facing the front of the pump.

 

(2) The oil will pass through the heater chamber and into the degassing chamber for dehydration and treatment. Thermo couple present prior to chamber to control heater bank temperature.

 

  • Heater bank elements are encased in tubes and the heater bank to be regularly checked for leaks – 220 volt = 2 kw heater dry air elements.
  • Coalescing filters to be removed, checked and refitted/replaced on a regular basis. Suggested cycle to be after every 75 – 100 thousand litres pumped through the plant or after every 4 to 6 months.
  • The high, low and foam level sensors to be inspected periodically for oil leaks and tightness of electrical connections.
  • The vacuum gauge and associated pipework to be regularly inspected for leaks.
  • The condenser chamber – green – to be drained regularly to ensure gauge glass orifices are open and clear of obstruction to ensure correct level. Recommended to be inspected prior to the operation of the plant on every occasion.
  • Vacuum pump to have correct oil level at all times and only Vacuum Pump specified oil to be used. Complete oil change if pump accidentally flooded with degassing chamber oils. Electrical connections to be checked periodically for tightness. Rotation of pump is specifically indicated and must operate only in the direction indicated.

 

(3) The delivery pump will draw the oil from the vacuum chamber and return the oil to the electrical plant via a flow meter, which monitors flow rate and volume pumped, then through a delivery filter vessel containing 20-inch one-micron cotton-on-tin filter cartridges, then into the delivery pipework. Delivery temperature indicator present.

 

  • Fine filter cartridges to be changed when pressure gauge indicates a 100 – 150 kpa increase.
  • Delivery choke valve to be regularly checked including all associated flanges and pipework.
  • Delivery pump to be removed, checked and resealed on periodic cycles approximately once every 18 months to 3 years of service defined by end user.
  • The rotation of the pump is specific to indicating the suction port of the delivery pump. Top-port will equal suction port with clockwise rotation when facing the front of the pump.
