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.
