CHONGQING GOLD Ultra High Voltage UHV Transformer Oil Filter Filtration Machine 9000L/H Transformer Oil Filtration System

1. Introduction for ZJA Series Transformer Oil Filter Machine:

The main function of ZJA Transformer Oil Filter Filtration Machine 9000L/H Transformer Oil Filtration System is to remove free and dissolved water, gases, and mechanical impurities from insulating oils so as to ensure its purity and improve its insulation property. It is suitable for the application to oil treatment up to 1000KV Ultra High Voltage UHV Transformer. It is also suitable for the treatment of capacitor oil, transformer oil and freezer oil.  

2. Features:

1) Doubles the evaporation area by adopting CHONGQING GOLD horizontal double vacuum separation technology efficiently and reliability thorough removal of gas in the oil by using coalescing oil spray separator.
2) Adoption of European brand fine filter, fineness: 2μm, ß≥1000.
3) Low noise and long life of the oil transport system.
4) Adoption of American heating technique with the way of thermal radiation, constant temperature control.
5) The use of float valve and photoelectric oil level control, eliminates supervision.
6) Adoption of French de-foaming technique to avoid oil leaking.
7) Controlled digitally and automatically by PLC.
8) Major electric apparatus are imported from Europe, so the controlling system safe and reliable.

6. Working Principle:

The oil to be purified enters the Rough Filter from the oil-in valve under the action of negative pressure.After filtering out impurities of large particles,Delivered to the heater by the oil-in pump.Heated to the set temperature by the heater(Controlled by an automatic constant temperature digital temperature controller), then enter the two-stage vacuum separation chamber, The oil through the atomizing injector to cause the hot oil to burst and atomize. Forming an oil film with a large expansion area step by step in a two-stage high efficiency separation column. The water and gas in the oil are rapidly vaporized under high vacuum to achieve the separation of oil, water and gas. The separated oil is output through a dedicated oil-out pump, The oil is sent to a precision filter to filter out mechanical particles. Complete a purification cycle, oil can meet the requirements of use.

Remark: If the user needs to vacuum dry some small volume containers,You can close the inlet and outlet valves,only need to open the spare exhaust valve
