1. Zhongneng Transformer oil filtering machine is designed for purifying used or aged transformer oil, Altrahigh-voltage transformer oil, switch oil and other insulating oils.
2. It is very suitable for power distribution station, power grid and various companies which need to install and maintain oil-immersed transformers.
3. Besides the regular transformer oil purification, this machine can be also used as vacuum oil injection and vacuum drying equipment for transformers, and it is cost-effective, easy to operate.

Features:
1. Besides vacuum pump, this machine installs Roots Pump vacuum system, which speed up air evacuation, make limited vacuum ≤ 5Pa, working vacuum ≤ 35Pa.
2. Large area three-dimensional flash distillation technique, advanced dewatering and degassing system, which remove water and gas rather quick and complete.
3. Precise filtration system, high-quality filter element, multi-stage filtration with gradual precision, which help removing mechanical impurities from oil.
4. After purification the breakdown voltage of transformer oil can reach up to 70KV.
5. Advanced double-infrared liquid level automatic controller, pressure automatic-protector, which ensure long- term safe and reliable operation.
6. This machine can be operated both on-load and off-load.
7. Humanization design, low noise pump, deep purification and long-term free technical instruction.
8. General type, Trailer-mounted type, Hermetical type, etc, which is available.
Advantage:
Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes the impurities more quickly and completely, and improves the oil breakdown voltage much higher. As the bridge-type vacuum linking system, it is used for filtration system as well as an independent vacuum power supply to vacuum oiling for power equipment.

Stainless Steel Precision Machining
Stainless steel materials have certain strength, corrosion resistance and toughness, so stainless steel parts are very suitable for many industrial occasions. Precision stainless steel machining parts occupy a large proportion in the stainless steel parts and CNC machining industries, and are used in almost all industries such as machinery, aerospace, equipment, construction, daily necessities, and automobiles. At present, in Precision Machining Parts, the most used stainless steels are 316, 304 and 303 and so on. Stainless steel 316 has the best corrosion resistance and the highest material and processing cost. Stainless steel 304 has moderate corrosion resistance and material and processing costs. Stainless steel 303 has lower corrosion resistance than 316 and 304, but the material and processing costs are also the lowest. . Of course, there are many other stainless steel materials, such as 201, 202, 302 and so on.
SCZY has more than 10 years experience in precision CNC machining. Especially in the processing of stainless steel 316, 304 and 303, we have very rich experience. Whether it is milling, turning or composite turning, our normal machining accuracy can reach ±0.01mm. If higher precision is required, we can cooperate with grinding Processing, up to ±0.002mm.
