I. What is the FUNCTION of the YELOCO Series YH-ZYD-R Double-stage vacuum Transformer oil Regeneration machine?

Series YH-ZYD-R Double-stage vacuum Transformer Oil Regeneration Machine is special for Regeneration and purification:

1) Transformer oil

2) Insulating oil

3) Cable oil

4) Silicone oil

5) Dielectric oil

6) Mutual Inductor oil

7) Switch oil

8) Natural ester fluid

The YH-ZYD-R Double-stage vacuum Transformer Oil Regeneration Machine not only provides regular oil purification such as degassing, drying and particulate removal but also can remove acidity, sludge, free carbon, other soluble oil decay products, and discoloration. This is accomplished by the use of high vacuum degasification technology and regeneration filters combined with our special brand of earth. After treating, the oil can be reused as new.

It is used for regeneration of very inferior insulating oil, reduce dielectric loss, remove acid, recovery the color.

II. Why need YELOCO Series YH-ZYD-R Double-stage vacuum Transformer oil Regeneration machine?

Series YH-ZYD-R Double-stage Vacuum Insulation Oil Regeneration system can make oil color significantly improved. No.6 10 dark-colored oil can be retrofitted to the color of No.2 4 oil.
Series YH-ZYD-R Double-stage Vacuum Insulation Oil Regeneration and oil filtration systems can recover aging insulating oil electrical characteristics PH value ≥5.5, Acid value ≤0.03 mg Koh/g, Dielectric Loss Factors tgδ (90℃) % ≤0.001, let oil specification back to new oil.
The treated oil neither damages the basic composition and antioxidant properties of the oil but also meets the new oil standard. At the same time, it improves the insulation and safety performance of the equipment, and the cost is 90% lower than the traditional oil change method.

IV. Which type of Vacuum pump, Roots pump and Oil Pump is most suitable for 12000L/H Transformer oil purification machine?

For Transformer oil purifier machine, when the flow rate more than 6000L/H, the machine vacuum pump and roots pump all need use air cooling type pumps. For example, if you choose common water cooling vacuum pump and roots pump, after you long times use machine, it need stop machine and add water to pumps to cooling pump. It is very Inconvenient. So we suggest Germany leybold vacuum pump and Shanghai CUIMAN roots pump or Germany Leybold roots pump or Germany Busch Roots pump to you. They are air cooling type pumps. They can long times operation.

For oil pump, when the flow rate is 12000L/H, we suggest three screw oil pumps to customer. Compare common gear oil pump with screw oil pump, the three screw oil pump advantages is working noise is very small, pumping capacity is strong. And during machine long time use, no any acetylene gas will be produced. It guarantees the purified oil quality is always high. We suggest China three screw oil pump or Italy three screw oil pump or Germany SIHI oil pump to customers.
