The two-stage vacuum oil filter uses a special evaporative separator, which uses the "vacuum" principle. The contact area of the oil in the vacuum separator has been expanded hundreds of times. The vacuum evaporation system has continuously increased the evaporation surface area of the oil, and the evaporation interface has been continuously updated, greatly increasing the oil stroke and the still water evaporation area in the vacuum system. Under the conditions of surface area and high pumping speed, the water in the oil can be quickly evaporated and discharged by the vacuum system.
The double-stage vacuum separation system and pressurization technology can make the vacuum degree of the vacuum separator higher than that of ordinary vacuum oil filter machines. The water and gas discharged from the upper part of the vacuum separator are cooled by the cooling system.
The dry oil in the vacuum separator after vacuum evaporation and dehydration is raised from negative pressure to positive pressure by the oil delivery pump. The purified oil after fine filtration is discharged from the oil outlet to complete the whole oil purification process.
It can be seen that the two-stage high-vacuum oil filter can effectively shorten the treatment cycle of oil purification and reduce trace moisture, and improve the maintenance efficiency of users.
Therefore, dual-stage vacuum is increasingly used for filtration, dehydration and purification of various lubricating oils. When two-stage high vacuum is used to treat insulating oil and transformer oil, the micro-moisture treatment value can reach 3ppm-5ppm.
When purchasing an oil filter from an oil filter manufacturer for dehydration and removal of impurities, especially when there is a requirement for the ppm value, it is recommended that the user inform the Kaiqian manufacturer of the detailed performance indicators of the oil, which will help you choose a vacuum dehydration filter that meets the requirements of use. machine is more helpful!
Generally speaking, the impurity content of transformer oil is not too high, but the requirements for trace water or gas are relatively high. Therefore, customers with special indicators must tell us your requirements, and let our professional technology recommend suitable oil filter units for you!
