Vacuum Oil Filter



Vacuum oil filter can quickly remove gas, trace moisture, and mechanical impurities from oil, thereby improving the insulation performance of the oil, making the filtered oil meet or approach the usage standard of new oil. It is an essential product for power industry and industrial and mining enterprises to treat oil used in electrical equipment such as ≤110KV transformers, mutual inductors, and switches.


  Vacuum oil filter is widely used in power plants, power stations, power companies, substation industries, railways, petrochemicals, metallurgy, and other fields. It can also be used for purification treatment of various low-viscosity lubricating oils, restoring and improving the withstand voltage strength and other performance of electrical insulating oil. It can process unqualified oil without stopping production, changing filter paper, replacing new oil, or power outage, and even when the transformer is running with electricity. It also has the functions of drying moisture in electrical equipment and vacuum oil injection for electrical equipment.


  If the vacuum oil filter has too many impurities and the filter element is clogged, the vacuum oil filter can filter water and impurities. The impurity filtering function is achieved through strong magnetic adsorption and filter element interception. Strong magnetism mainly adsorbs iron metal, while other impurities are mainly intercepted by the filter element. Once too many impurities are intercepted and the filter element is clogged, on one hand, it shows excessive pressure, and on the other hand, the oil filtering becomes slow. In severe cases, it directly damages the filter screen. If the heater is damaged, the oil viscosity increases, fluidity becomes poor, and oil filtering becomes slow. Generally, the heating system of a vacuum oil filter has two functions: heating the oil to increase fluidity and increasing oil temperature to achieve vacuum evaporation.


  The filter element should be cleaned regularly. If it is a plate and frame oil filter, the filter paper should be replaced. After the filter element or filter paper has been used for a period of time, it will intercept a certain amount of impurities and clog the filter element pores. If not removed, it will slow down the oil flow rate during oil filtration, reduce the working efficiency of the oil filter, and the filtering effect will also deteriorate. Therefore, it is necessary to regularly clean and replace the filter element and filter paper. When cleaning the filter element of the oil filter, special attention should be paid to the stainless steel wire mesh. The stainless steel wire mesh is a vulnerable part. During cleaning, it is easy to damage or deform if not careful. If the stainless steel wire mesh is damaged or deformed, it should be replaced in time to ensure the filtering effect is not affected.
