Description
ZLAseries 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/T*******4. 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 over**0KV 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.
*0.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
IP*5.
