Short Description:

Vacuum drying and Oil Filling equipment is designed and manufactured according to the principle of transformer vacuum oiling and vacuum drying, which is mainly used for drying the active part of oil immersed transformer.
In the drying process, the vacuum equipment constantly changes the pressure in the drying tank to make the product heat up evenly, and can timely remove the evaporation water in the tank to prevent the iron core from rusting. Because of the gradual drying, the product deformation is small and the drying is more thorough. Due to the reasonable structure and technology of the equipment, the drying time is about 40% less than that of the conventional vacuum drying. It is a reliable, efficient and energy-saving process equipment.

Product Detail



Feature of Pressure changeableVacuum drying and Oil Filling equipment:

1. oil tank and oil pipeline using 304 stainless steel, no impurities and pollution; oil filling  is done in two ways of automatic and manual, accurate control of oil filling.

2. the vacuum system design has a new type of condenser, so that most of the moisture from the condenser cooling, condensed to water and released, effectively avoid moisture in the drying process of to affect the vacuum pumps. The high temperature magnetic pump is used as the heat transfer pump to make the heating system more stable and avoid the leakage of heat conducting oil.

3.In the process of heating the body temperature according to different times, automatic pressure exchange and transformation will be reduced to a certain value in the vacuum tank pressure cycle, create the most suitable conditions for the moisture evaporation from the insulation part of the active part during the evaporation process of drying process in a reasonable state.

4.Because of the scientific control of variable pressure drying process, combined with domestic and foreign technology, can effectively solve the iron core rust problem in the drying process.

5.The level of automation and product processing reach to advance level, the quality of products handled can reach the level of superior class in the industry.

6.This equipment electric control system and each component system is stable and reliable, can guarantee the smooth operation.
