Raining Proof Type High Efficiency Vacuum Electric Insulating Oil Purifier Machine for Power Plant Maintenance
working principle
When the oil filter is working, the oil enters the primary filter through the inlet under the action of the pressure difference between the inside and the outside, and the large particle impurities are filtered out. After the oil is heated by the multi-stage infrared, it enters the special personalized vacuum separator and is separated in the vacuum. The mist is formed in the first shape, and then formed into a film shape, so that the contact area in the vacuum is expanded by hundreds of times. The moisture in the oil is rapidly obtained under the conditions of high heat, high vacuum, large surface and high pumping speed. It is vaporized and discharged by a vacuum system.
The water vapor discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser, then cooled into the cooler, and the condensed water is discharged into the water storage device, and the gas after being condensed and dehumidified twice is finally discharged into the air by the vacuum pump.
The dry oil after vacuum dehydration in the vacuum separator is raised from the negative pressure to the positive pressure by the oil pump, and after filtering, the clean oil is discharged from the oil outlet to complete the entire oil purification process.

Automatic PLC Equipped Double Stage High Vacuum Transformer Oil Treatment Machine | Vacuum Oil Dehydration Plant ZYD-100 is mainly used for electric power department and industries to deal with various oils such as transformer oil, mutual oil, switch oil, insulating oil, dielectric oil and so on. The transformer oil purifier machine is especially for purifying the insulation oil in all kinds of large power equipment that are above 110KV, especially for the altitude is over 500-1000 meters. Our transformer oil filtration unit can remove the free and dissolved water, gas and particles from oil high-efficiently, and improve dielectric value of treated oil to be higher than 75~85KV, and increase the pressure force and quality of oil, make sure the electric device running safely. This oil purification system is very suitable for the large power electric equipment and transformers.
Advantage:
ZYD-100 Double-stage vacuum transformer oil treatment machine can quickly remove water, trace water, dissolved gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's dielectric strength, effectively making sure electric equipment working safely and normally. As the bridge-type vacuum linking system that also can be an independent vacuum power supply, which can vacuuming and oil injecting for electric insulation devices.
