Hydraulic oil filtration system
High vacuum oil purifier, or commonly known as degassifier, is a machine that purifies the insulating oil of high voltage equipment. Degassifier consists of heaters, vacuum pump, centrifuge pump and filters that work together inorder to improve the insulating capability of the HV equipment insulating oil. 

The heater is important as this will "cooked" the insulating oil that passes through the degassifier. Through this cooking method, the water and moisture content of the insulating oil will be eliminated. The "cooked oil" will then go through an enclosed chamber. Inside this chamber, the insulating oil will be subjected to vacuum pump and centrifuge pump. The vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum . Therefore, this vaccum pump will remove other gases in the oil that can contribute to low level of insulation like acetylene, hydrogen, ethylene, etc. The centrifuge pump is also operated to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through piping. 

 The constant stirring of the oil by the centrifuge pump will also make the oil vacuuming more effective. Then, the treated oil will be collected to a basin, where it will be pumped again to a filter. The resulting oil will be transferred to a collecting container where it will be ready to be pumped to the desired equipment. There are two types of degassifier, the off-load degassifier and the on-load degassifier. As the name implies, these degassifiers can be operated to an equipment which is energized (on-load) and de-energized (off-load). Degassifiers can also be used to refill a power transformer. Most of the time, only the heaters are left operational and centrifuge pump, vacuum pump and the filter are bypassed during refilling, especially when new insulating oil is being refilled.

Solve the excessive use of transformer oil dielectric loss in two ways: one is the replacement of substandard oil, re-injection by electrical test and chemical analysis of the indicators are qualified oil; the other is the excessive oil recycling process. 

1 replace the failed oil.
Replacement of substandard oil can reduce system outage time, the net just put the old oil inside the transformer, the transformer oil with a qualified rinse, and then the transformer vacuum oil purifier. This treatment is more suitable for the unit does not allow an extended power outage; unit operation for a long time, the higher the value of oleic acid, dark yellow or brown oil, or oil-free water appear cloudy phenomenon, and overall degradation of the situation. But the simple transformer oil filtering oil as a "wash" thorough and oil-consuming, it is not conducive to energy conservation and environmental protection, excessive oil should not be the first choice for oil processing. 

2 regeneration process. 
Regeneration process is the physical-chemical or chemical methods to remove harmful substances in the oil, restore or improve the physical and chemical indicators of oil. Regeneration process commonly used methods are: a white absorbent indigenous law and sulfuric acid. Sorbent method for dealing with degraded to a lesser extent oil; sulfuric acid treatment for white indigenous degradation of heavy oil. Sorbent method can be divided into contact with law and the percolation method, the contact law using powdered adsorbents (such as clay, 801 adsorbents, etc.) and exposure to oil in the mixing mode of regeneration; the filtration method with which to force the oil through the granular adsorbent (eg silica gel, activated alumina, and clay particles, etc.) purification, the leachate recycling processing. For more serious deterioration of transformer oil, white indigenous sulfuric acid can be used for regeneration treatment. Sulfuric acid to remove the oil in a variety of aging products, clay treatment can eliminate the residual acid in the oil bad thing. In the actual production and operation, often encountered in oil by vacuum filtration and purification treatment, oil water content is small, the oil dielectric loss due to the higher value, and this is because the oil is not only the number of dielectric loss with water, but also with a number of factors related. 

From the above analysis can be found, most of the transformer oil dielectric loss factor increases because the oil soluble polar substances (such as sol, etc.) due to the increase. For the sol particles having a diameter of 10-gm ~ 10-Tm between, through the filter paper, therefore, the two vacuum oil filter processing can not achieve its purpose of dielectric loss factor, so by this process causes the oil dielectric loss factor increasing problem, usually filtration assay regeneration treatment can get good results.

To improve transformer oil, insulating oil dielectric strength, making less trace moisture content, gas content, dielectric loss factor and other indicators, before pumping transformer oil into the tank must be preceded by a rigorous treatment, the effective removal of oil in the water, gas and impurities. In practice applications, we have for different types of transformer oil, insulating oil using different forms of oil filter for targeted treatment, results were better.

1. For the general transformer are impurities, water and dust contaminated transformer oil, you can use the JL pressure transformer oil filter, through a series loop filter, is usually able to meet the requirements. Its principle is to use oil filtering paper to absorb moisture, filter impurities. Advantage is a subtle effect of impurity removal is good, its simple structure, convenient maintenance, reliable operation, easy handling, so widely used. The disadvantage is that water filters are not thorough; it only applies to low-voltage level of transformer oil, insulating oil filtration.

2. Now generally used a vacuum oil purifier (there are ZY single stage vacuum transformer oil purifier machine ZYD double stages vacuum transformer oil purifier), it can not only completely remove the oil water and gas, but also can effectively remove small impurities. The process is: when dealing with coarse filtration of transformer oil → → → heating oil fine filtration vacuum degassing → Absolute dehydration. Coarse metal mesh filter and strong magnets, fine filtration is usually 1 ~ μm micro-filter impurities. At present many different types of fine filters, sintered metal powder material, metal microporous materials, ceramic filter media and the use of special structure of filter paper filter core and so on. 

Transformer oil heating degassing vacuum dehydration. The principle is that the vacuum inside the tank, the heating of transformer oil with the formation of oil mist spray approach, leaving the oil in the gas and water escape. Oil temperature around 60 ℃ in general, not too high so as to prevent aging of transformer oil. This approach dehydration degassing effect is better, is more commonly used methods.

If the oil is sprayed into the oil has a certain diameter beads, the beads due to higher oil interfacial tension, making the oil water and gas within the beads difficult to bring into full play. To this end, the diameter of injection holes to choose appropriate, and generally taking the time to be in the tank set up with a few baffles the mouth to prevent the transformer oil is pumped vacuum. 
At present, foreign and domestic has also adopted a more advanced membrane dehydration degassing method is to make the oil into the tank, through a degassing components formed after the thin oil film, and has always been to film the entire process of degassing state of complete dehydration , thus making the water in oil and gas easier to remove.

3. Badly contaminated transformer oil filter/oil regeneration (Choose our BZ oil regeneration device).Contaminated transformer oil (commonly known as dirty oil), is being mixed with very small impurities and oil molecules combine to form a colloidal contaminated transformer oil, and after years of used transformer oil, the general product release for the repairing of oil (This oil has a very low pH value). Of such waste oil must be used in order to improve the absorption approach to oil targets. Were more commonly used silica (SiO2) or activated alumina (A12O3) as adsorbent. Waste oil processing system in order to ensure full access to silicone and transformer oil, and to facilitate replacement of silica gel, silica gel tank set up in a number of partitions, the silica gel into a small cloth bag within the rotation, not in bulk. After the heating of the transformer oil into the gel tank, do a certain time cycle to its full absorption effect, and then injected into the Absolute through the oil filter tank. In the process should be regularly monitored to determine the absorption effect, when the absorption effect is not apparent that it should consider replacing the silica gel. General silicone oil consumption by weight or about 3% ~ 5%. Waste oil processing system with the new oil-processing systems should be separated to avoid cross-contamination. Loading used waste oil cans, containers, etc. must be thoroughly cleaned before be used for the normal production of the oil system.

The Double-horizontal vacuum evaporation vessels can enlarge evaporation area efficiently. The heater, being places in the vacuum vessels, becomes an evaporator. Thus the evaporation areas of Double-horizontal vacuum vessels are three times more than of the common vacuum vessel. This innovation can dehydrate and degas effectively and separately. This optimal structure of the dehydration (degas) system enlarge the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.
