Product Description

                                       ZLA-150 Double -Stage Vacuum Oil Purifier
ZLA series double-stage vacuum transformer oil purifier is suitable for dehydration, degasification and purification process of insulating oil. It is developed and produced by Wanmei company to treat varieties of insulating oils with different kinematic viscosity and flash point. It is an ideal equipment for factories, mines, power station, transportation department and other enterprises to purify different kinds of insulating oil and other low viscosity lubricating oils. The double-stage is much more efficient than single -stage vacuum oil purifier.
Application
ZLA series is manufactured according to vacuum dehumidification principle, separation technique, precise filtration and many other patented techniques. It completely abides by national standard DL/T521-2004. It's a professional equipment for purifying all kinds of unqualified insulating oil. It's widely used in most industries like metallurgy, machinery, oil field, chemistry, mining, power generation, transportation and manufacturing to purify various kinds of transformer oil, especially the fine purification treatment of high-grade new oil, imported oil and super-voltage transformer oil. It can be used for online operation in over110KV transformers, especially even at high-latitude areas. It can quickly eliminate the polar material, mechanical particles, moisture, light hydrocarbon and acetylene. ZLA series also can be used as drying equipment for a variety of electric facilities. And it is widely used for oil filling for transformers and circuit breakers under vacuum condition.

Structure & Features
1.Three-dimension Flash distillation system
Importing the technologies from some famous brands like German HERING, American PALL and Japanese KATO, this system consists of Three-dimension Vacuum Flash Evaporation Chamber, Flash Pall Ring, Semi-circular Sprayer and Flash Evaporation Plate etc. It can deeply remove the water and gas from the oil.
2.Foam Level Detector and Defoamer Device
Adopting high-sensitivity liquid level controlling system, it can control the oil level in the vacuum flash distillation chamber automatically and ensure the oil level to adjust at a proper range by itself,
3.Oil Pumping System
It owns some advantages like steady operation, without damage on gearing surface, without oil barrier, low noise, long usage, high efficiency and free maintenance etc.
4.Filtration System
Precise multi-stage filtration system makes a high precision reinforced stage by stage. The filters adopted have large capacity of containing pollutants and are able to eliminate the mechanical particles in the oil effectively.
5.Heating System
Our electric heating system adopts unique design and process. It has some merits like heating evenly, keeping oil temperature constant, heating quickly, without dead area and very low surface heating load(≤1.5W/2)etc.
6.Electric Controlling System
Electric Controlling System is designed according to IEC standard, whose main electric components are from French SCHNEIDER brand, which stable performance can ensure the equipment work continuously and also makes the operation and safety protection more humanistic.
7.Multi-protection System
This machine is equipped with fine protection system and with very high automation level. By the interaction and combination of relevant components,
8.Double Liquid Level Controlling System
High-sensitivity ball float liquid level controlling is able to control the oil level in the vacuum flash distillation chamber automatically.
9.Large Suction Velocity And Drainage System
Adopt double-stage vacuum system (vacuum pump+ roots pump) to get a high vacuum status. The vacuum pump is originally from German LEYBOLD, its high suction velocity is able to reach the max limit of vacuum. It owns many merits like tight structure, slim size, low noise, low vibration. It's also installed with an internal check valve to stop the oil from backward.
10.Instruments
The instruments adopted include liquid level meter, vacuum meter, platinum resistance, digital temperature controller and electric contact pressure meter. The grade of the instruments is above IP55.
