Model VOF Vacuum Oil Filling Unit is developed and produced by PureTech for filtering impurities and vacuum injection of various mineral and vegetable liquid oils such as transformer oil, hydraulic oil, turbine oil, etc. For instance, the preparation (degassing), storage, transportation and adding transformer oil in the bushing of transformers, height-voltage ports of transformers and switches. This oil filling unit can be used on power plants, substation and other energy facilities.
Turn on the vacuum pump, when the vacuum value reaches -0.065～-0.095Mpa, you can insert the oil pumping gun into the oil storage tank. The vacuum control range is -0.07±0.02Mpa (customer setting). When the vacuum value is higher than this, the oil filling unit will automatically stop to ensure no backflow; when the vacuum value is lower than this, the unit will automatically start and vacuuming the equipment.
In the case of vacuum negative pressure, the oil passes through a strong magnetic filter to remove large metal particles in the oil and is sucked into the vacuum tower. Its storage capacity can be observed from the level gauge.
The oil in the vacuum tower is pumped into a clean oil drum through an oil transfer pump. When the oil level reaches a certain position, the oil transfer pump is turned off to achieve the oil transfer function.
• Light, flexible, and easy to move and operate.
• No filter paper is needed and the site is not polluted.
• Sophisticated filtering system can filter out mechanical impurities in various oils, and can meet the requirements of long-distance, high-lift refueling and pumping.
• More convenient and practical to change oil and filter impurities for gasoline engines, oil switches, transformers, compressors, refrigerators, machine tools and other equipment that use a small amount of oil.
