Single -class vacuum filter machines are mainly used in power plants, substations, power industries, railways, metallurgy and other industrial and mining enterprises purify transformer oil, transformer insulation oil, circuit breaker oil and switching oil. It can quickly and efficiently remove water, gas, impurities, water -soluble acids, etc. in oil, and can increase the pressure resistance value after treatment. It is an ideal equipment for hydraulic oil and lubricating oil treatment. In the installation and maintenance of various large transformer equipment, the dual -class vacuum filter is widely used for oil purification treatment and the vacuum thermal oil is dry. It can also be used for transformer oil treatment in the main almed box.

Single -class vacuum filter machine is different from double -class vacuum filter machine:

Compared with a single -stage vacuum filter machine, the double -stage vacuum filter machine has increased the Rockz pump supercharged system, the secondary high vacuum separation system, the automatic control system of infrared scanning, and the three -dimensional three -dimensional rapid evaporation system. Its dehydration, offing, removing acid values, removing free charcoal, etc. After processing, the hydrotometer has a higher voltage resistance after processing. It can not only be used as oil filtration, but also can be used as an independent vacuum source to perform vacuum drying and oil injection functions of transformer equipment.

Two -stage vacuum oil filter machine working principle:

Water dissolves in the transformer oil until the internal pressure balance in the oil. If the pressure, temperature and saturation related to the balance pressure are destroyed, the transformer oil may overflow or absorb water until it meets a new balance under new conditions. The working vacuum of the DLA series vacuum filter machine is within 133Pa and the oil is fog to be less than 50um, so as to quickly reduce the water in the oil to less than 3ppm.
