The principle and application of Transformer Oil Filtration Machine from luis huang's blog

The coalescence dehydration Transformer Oil Filtration Machine includes two systems, the coalescence system and the separation system, each of which plays a different role. The coalescing system consists of a set of coalescing filter elements. The coalescing filter element adopts a unique polar molecular structure. After passing through the filter element, the free water and emulsified water in the oil coalesce into larger water droplets and settle to the water under the action of gravity. inside the water tank. The separation filter element of the separation system is supported by a special hydrophobic material. When the oil passes through the filter element, the water droplets are held on the outer surface of the filter element and coalesce with each other until they settle into the water storage tank due to gravity.

This type of oil filter uses "coalescence separation" technology for dehydration, with high dehydration efficiency and strong capacity, especially suitable for the separation of a large amount of water in the oil. It has the incomparable advantages of vacuum method and centrifugal method. All oil-water emulsification structure; through the filtration of the particle filtration system, the cleanliness of the medium can be stably controlled within the required range of the system to ensure the cleanliness of the oil; it does not change the physical and chemical properties of the oil, prolonging the oil Long service life; low energy consumption, low operating costs; excellent system configuration, strong continuous workability.

The oil filter has a total of five filter systems:

The first-stage oil suction filter is located at the oil suction port. The coarse filter protects the oil pump and prolongs the service life of the main filter.

The second-stage pre-filter is arranged upstream of the coalescer, which can prolong the life of the coalescer and reduce the content of particles in the liquid after Lv.

The third stage filter The coalescing filter causes the water in the oil to condense and sink.

The fourth-pole separation filter further blocks the tiny water droplets in the oil to achieve high-efficiency separation.

The filter medium of the fifth season filter adopts the filter material with high precision and large dirt holding capacity, which can purify the oil safely and efficiently.
