Double Stages Insulating Transformer Oil Purification Machine With Leybold Pumps
Application:
DVP series double stages vacuum transformer oil purifier is special designed for processing insulating oil of high voltage electric equipments(especially for more than 500KV UHV insulating oil) in workshops or the field, storage tanks or drums, it adopts double stages vacuum source, double stages vacuum dehydration and degasification vessels, three stages precise filtration system, which can separate moisture, gas, particles and other harmful ingredients from oil much quickly and effectively to ensure the dry-level and dielectric strength improving greatly.. Meanwhile, DVP machine can be used for online oil treatment for transformers and vacuum drying and oil-pumping for electrical equipment. It is also applied to the above 110KV EHV transmission and distribution equipment, capacitor oil, cable oil, mutual inductor oil etc.
For DVP150 luxury type machine:
This is the luxury type of our DVP150 model transformer oil purifier machine with PLC automatic control system,it can treat 150L/minute(6000L/hour) transformer oil,this machine produced with Europe famous brand Germany Leybold vacuum pump and root pump,Schneider electric parts,Siemens S7 PLC ,On-line Moisture detector,Flow meter etc,we also could supply the China famous brand pumps and other parts as customer required. This DVP150 automatic type transformer oil purifier machine mostly suitable for more than 500KV UHV insulating oil of the large power plant, power engineering, power station etc.
Features:
1˃ vacuum-pump imported from Germany Leybold, with high air pump speed so as to get high working vacuity.
2˃ vacuum-segregating employs a particular stainless steel,foldable column for dehydration and degassing ,and enlarges the area of separatingto facilate three-dimensional evaporation, so as to abtain enough time for degrassing and achieve the best effect of separation.
3˃ Using new type of heating equipment,low heating load and is able to prevent oil from ageing.
4˃ Oil level control adopt photoelectric way ( the main components is imported from Switzerland )and features a very sensitive precise control. Even foams can be sensed, and thus there is no possibility of oil spray.
5˃ Personalized design, customers can require to choose their components are all or partyly imported from overseas. Include touching screen and flow gauge is can be selected according to customers. This series could meet different kinds of customersneed.
6˃ It equips filter elements imported from Italy, Germany or U.S.A(optional),which has large filtering area, strongly absorbent-dirt capability, high filtering precision.
7˃ Whether clients choose the oil pump from domestic or abroad, they all must be air proofed by our factory, they are free from oil leakage, low in operation noise, and long in using life.
8˃ Horizontal double vacuum separation technology, doubling the evaporation area and degassing time
9˃ Double stages vacuum source and dehydration, degasification system, vacuum pump with roots pump, high speed vacuum evacuation, ultimate vacuum ≤ 5Pa
10˃ Multi-stage precise filtration system with gradually increasing precision, which can effectively remove mechanical impurities from oil.
11˃ Automatic double-infrared liquid level controller, pressure protector, which ensure long-term safely and reliable operation.
12˃ Fully automatic temperature controlling system and multi-stages electric oil heater adopts low-load design to ensure uniform heating oil, the load is less than 1.0W/cm2, oil level and temperature protection of heater, which avoid cracking and aging of oil.
13˃ Automatic defoaming system with dual electronic monitoring system, which avoid the foam ejecting and gushing to vacuum pump.
14˃ Online oil treatment, vacuum drying and vacuum oil-filling for electric equipment.
15˃ Advanced cooling system of vacuum pump, it reduces the frequency of oil’s replacement and extends the life of vacuum pump.
16˃ Interlocked protective system connects oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.

1˃ Double-stage, high vacuum can highly effectively remove the water
in the oil. It can improve the breakdown voltage, the amount of
degassing, the degree of dryness and the effect of one-time
filtration.
2˃ Precise filtration system, multi-stage filtration can remove
particulate impurities in the oil. High-quality filter medium has
strong mechanical strength, high ability of containing pollution,
corrosion proof and wear well.
3˃ Highly effective degassing and dewatering system that use large
area three-dimensional flash vaporization technology to remove the
water and gas in the oil.
4˃ Advanced pressure protection, infrared liquid level control system
and chain control system for electric heating make the operation
safe.
5˃ It can dry electric machines and vacuum add oil to transformers.
