The double-stage vacuum oil purifier is an upgraded version of the single-stage vacuum oil purifier, with higher filtration accuracy and faster speed. The double-stage vacuum oil purifier has two Roots pumps, while the single-stage vacuum oil purifier has only one Roots. Pump.
The single-stage vacuum oil purifier in the transformer oil purifier is a vacuum oil purifier with only heating and a vacuum pump, which can handle water and impurities, and cannot vacuum the transformer. The two-stage vacuum oil purifier is based on the single-stage vacuum oil purifier with a Roots pump, which has a large pumping speed and can quickly and efficiently remove the water vapor in the oil. The one-time filtration effect is greatly improved, the oil treatment period is shortened, and the performance of the oil is improved, and the transformer can be evacuated, which can also be used at high altitudes. In addition to filtering and purifying oil, the bipolar vacuum oil purifier can also conveniently switch valves for separate oil pumping, oil injection, oil replenishment, and functions, so as to filter particles while delivering oil, so as to meet the requirements of multi-purpose use on site.
