Applications of Transformer Evacuation Vacuum Pump for Transformer Maintenance

  1. The transformer evacuation vacuum pump is used in vacuum smelting, welding, drying, chemical and pharmaceutical, electric vacuum devices, and other industries such as vacuuming.
  2. Maintenance is used to extract the vacuum of the electrical vacuum device in the transformer substation, administration of power supply, power generation plant, and transformer manufacturer, ZJ operates in a vacuum degree of 133Pa, and its limit vacuum degree is 1Pa.
  3. It has the characteristics of quick start, high pumping speed, stable performance, and easy operation.
  4. It is especially convenient for vacuuming, vacuum oiling, vacuum drying, etc., of transformers or electric equipment.
  5. The unit can be equipped with an imported vacuum pump or an imported roots pump as needed.
  6. The unit uses a roots pump as the main pump and a rotary vane vacuum pump as the foreline pump.
  7. An electromagnetic vacuum inflation valve is connected in series between the foreline pump and the main pump and is opened and closed with the front stage pump switch.
  8. An electronic vacuum gauge can be installed at the air inlet of the unit to accurately observe and control the vacuum of the pumped container.
