Working principle of high-efficiency vacuum oil filter

ZJBWorking principle of high-efficiency vacuum oil filterAlso known as vacuum high-efficiency oil filter, oil filter, vacuum oil purifier.
High efficiency vacuum oil filter and vacuum oil purifierDesigned based on the principle of different boiling points of water and oilIt consists of a vacuum heating tank, a fine filter, a secondary filter, a condenser, a primary filter, a cooling device, a vacuum pump, an oil discharge pump, and an electrical cabinet.
Working principle of vacuum oil filter:Under the action of internal and external pressure difference, the oil enters the primary filter through the inlet, and large particles and impurities are filtered out. After multi-stage infrared heating, the oil enters a specially customized vacuum separator, where it first forms a mist and then a film, expanding its contact area in vacuum to hundreds of times its original size. The moisture in the oil is quickly vaporized under high heat, high vacuum degree, large surface, and high pumping speed conditions and discharged from the vacuum system.
The water vapor discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser, and then enters the cooler for further cooling. The condensed water enters the water storage tank and is discharged. After two rounds of condensation and dehumidification, the gas is finally discharged into the air by the vacuum pump.
The dry oil liquid after vacuum vaporization and dehydration in the vacuum separator is pumped from negative pressure to positive pressure by the oil transfer pump, filtered, and then discharged from the outlet to complete the entire oil purification process.

ZJB high-efficiency vacuum oil filterPurpose:This machine is suitable for purifying and treating unqualified transformer oil, transformer oil, switch oil, capacitor oil, electrical insulation oil, cable oil, circuit breaker and other insulation oils. It is an equipment used for purifying and treating unqualified electrical insulation oils in power plants, power stations, power companies, metallurgy, petrochemicals, railways and other industrial and mining enterprises. It can also perform vacuum injection and vacuum drying of insulated power equipment to remove moisture from electrical equipment.
characteristic:
1. Three dimensional flash evaporation, efficient dehydration and degassing.
The combination of mesh filtration and polymer adsorption for impurity removal technology reduces the cost of equipment consumables, improves filtration accuracy, and achieves effective filtration and purification.
3. HavingAutomatic anti dry burningThe automatic foam eliminating device can effectively prevent the vacuum system from running oil and spraying oil; Equipped with highly sensitiveAutomatic control of red external line liquid levelSystem; This machine is also equipped with a safety protection system. When the filter pressure is too high, the motor is overloaded, overcurrent or operates in violation of regulations, the equipment will automatically stop and sound an audible and visual alarm, providing protection for the whole machine and eliminating the worries of operators.
4. This machine can perform vacuum oil injection and vacuum drying on insulated power equipment such as transformers.
5. It has a unique vacuum oil injection function, which is very convenient for maintenance and new installation of transformersIt can achieve moisture free oil filling of transformers in a vacuum state to ensure the dryness of the internal coils and iron cores, and to ensure the quality of oil filling.
6. At the same time, this machineEquipped with live online operation function, the safety is very high.
7. This machine has a three in one interlocking electrical automatic protection device (phase sequence protection, overload protection, overvoltage protection), using our company's specially designed precision oil pump, low noise, and meets the high environmental standards of the world.
8. A convenient and simple online drainage device that can achieve non-stop drainage. Completely avoiding the shortcomings of shutting down similar models and first breaking the vacuum before discharging condensed water, improving work efficiency and making operation more convenient;
9. A fully automatic insulation strength tester can be randomly equipped to detect the withstand voltage value, which can automatically test and print the results of insulation strength detection values (ZJB-T series).
10. This machine canUsed together with the BZ series transformer oil decolorization device, it adds functions such as acid removal, decolorization, free carbon removal, and reduction of dielectric loss(ZJL series).

Advantages:Working principle of high-efficiency vacuum oil filterBelonging to a new type of high-efficiency vacuum oil filter, it has three-dimensional flash evaporation and microgram technology, and adopts a combination of mesh filtration and polymer adsorption for impurity removal technology. Its efficiency is 5-8 times higher than that of general vacuum oil filters, and no other consumables are required, with extremely low energy consumption.
