The filtration accuracy of oil filter is affected by these factors

The oil filterincludes a primary filter, oil pump, vacuum evaporation tank, filter device and other parts. After the action of atmospheric pressure, the impure oil passes through the initial filter into the vacuum evaporation tank. After the oil is heated and sprayed into the vacuum chamber, it can become tiny droplets of oil. The water in the oil can quickly evaporate into steam and then be discharged.

Collected at the bottom of the vacuum evaporation tank, the evaporated and dehydrated oil is sent to the filter device by the oil pump to filter out the solid impurities in the oil and further absorb the trace water. The oil filter function can significantly improve the effect of removing water in oil, which is suitable for the purification of high voltage electrical oil. The new molecular oil cleaner also uses electrostatic separation and resin adsorption technology, which can remove the deteriorated oil molecules, make the insulation oil highly purified, improve the insulation performance.

Hydraulic oil filter is mainly used for hydraulic oil filtration in hydraulic system, used to filter out the particle impurities and rubber impurities in the hydraulic system, to ensure the cleanliness of the hydraulic system. Increase the axial pressure, so that the oil can pass through the filter screen faster, but it will often crush the filter element. Add preheating tank to increase temperature and reduce viscosity.

The selection of filtration accuracy of oil filter is mainly affected by two factors. One is the need for oil. Insulating oil, for example, can achieve high insulation value through high precision filtration, while large modulus gear requires much more extensive impurities. The second is the viscosity of the oil. High viscosity oils cannot pass through fine screens, requiring reduced accuracy. If one-sided emphasis on the cleanliness of the oil and the use of precision screen, it will increase the operating cost of the oil filter. The filter element is often blocked and needs to be cleaned or even replaced frequently.
