Double-Stage Vacuum Insulating Oil Purification System (ZYD-30)

ZYD seriesDouble-stage vacuum insulating oil purification system is specially designed for improving oil's dielectric strength and making sure electric equipments working safely and normally. ZYD Double-stage vacuum insulating oil purification system equipped with double-stage vacuum system, it can quickly and effectively remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from unqualified insulating oil. ZYDDouble-stage vacuum insulating oil purification system s particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil.

Double-stage vacuum insulating oil purification system Main features:
1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value 2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and greatly improve dielectric strength.
3. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7. The ZYD machine adopts advanced technology, the final treated oil can achieve:
Water content less than 3ppm
Particles size less than 1 micrometer

It can be used for filtration of more than 110V substation live line work onsite. Also, ZYD Double-stage vacuum insulating oil purification system can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.
Double-stage vacuum insulating oil purification system, is a kind of equipment for filtering solid impurity, water from oil, and improve the performance of transformer oil, insulating oil's insulation intensity.
Double-stage vacuum insulating oil purification system Working theory:
When the oil purifier working, then oil enters into the machine with the help of the domestic and foreign oil different pressure, and oil flow into primary filter, the large impurities will be filtered. The multilevel infrared ray heating system will heat the oil, and the oil flow into the special personalized vacuum separator, first, the oil is mist, then becomes into membrane, so the vacuum of contact area expanded hundreds times, the water, gas will be removed out through vacuum system under the high fever, high vacuum degree, large surface, high pumping speed conditions.
