ASSEN ZYD type Double-stage Transformer Oil Purifier machine is widely used in electric power, petroleum, chemical industry and railway etc. It can purify oil in fieldwork with additional installation of a trailer, a damping spring steel plate, a brake and cornering lamp, this guarantee the safety and reliability when moving in fieldwork. It is also used for hot oil circulation drying and oil purification when various large transformer equipment installation and maintenance. Purifying insulating oil in 110KV-330KV transformer, also suitable for high grade new oil, imported oil deep purifying.
● Optional P.L.C. intelligent panel control, touch screen operation and dynamic display according to user needs.
● Optional Online PPM Meter, Optional flow meter with accumulator function.
● Optional frequency converter, you can adjust the flow according to your needs
● Optional external port design for transformer vacuum pumping
● The whole structure can be made into mobile, fixed, fully enclosed, concealed, canvas, open type.
● Optional three stage high vacuum system for higher vacuum degree work.
The oil’s performance after treatment:
Moisture PPM ≤3
Gas content % ≤0.01
Impurity size μ ≤1 (no free carbon)
Breakdown voltage kV ≥75
IFT dynes/cm ≥40
Acid value mgKOH/g ≤0.03
Dielectric loss factors tgδ(90°C) ≤0.001
1. A capability of reducing moisture content from 50ppm to 3ppm moisture and 12% gas content to less than 0.1% by volume. 98% of particulate matter will also be removed.
2. Double-Stage vacuum system,strong power of vacuum evacuating,ultimate vacuum value no more than 5Pa
3. Duplex-Stereo film evaporation technology,combined with unique and advanced dewatering,degassing components,can rapidly and effectively separate water, gas,from oil.
4. An advanced fully automatic temperature controlling system,liquid-level controlling system,defoaming controlling system,pressure protecting system and excellent configuration can ensure operation of the equipment with high performance
5. Online work,allowing separated operation of manual operators from machine with lamps indicating the condition for operation.
6. It is humanization design with low noise,deep purification and long time free maintenance to save cost from the running process.
