4000 L/hour Power Transformer Oil Purifier Machine Electric Oil
Filtering Equipment
Application:
The model DVP vacuum oil purifier use new vacuum drying
theory,separation engineering and precision filtering technology to
eliminate the water,air and impurities from all kinds of mineral
oils high-effectively and reliably under vacuum state.It can purify
the losing-efficient insulation oil and make the oil reach the new
oil standard without power cut,not changing the oil,not using
filtering papers.They are widely used to purify the insulation oil
of the transformers,sensors,oil switches and electricity condensers
in the power generation plants,power stations,mines,mechanical and
chemical industry.
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.
About this machine:
This DVP65 model transformer oil purifier machine is our latest
type with PLC system and auto defoamer system,it design as two
vacuum chambers,can treat 65L/minute(4000L/hour) transformer
oil,this machine can be produced with Europe famous brand
pumps.such as Germany Leybold ,Kracht,ABB or China famous brand
pumps as customer required. This DVP65 automatic type transformer
oil purifier machine mostly suitable for power plant,power
substation,power engineering,the power supply house,hydroelectric
power station,metallurgy, railway ,wind or coal power
station,transformer oil purify service agent etc.
Features:
1) Horizontal double vacuum separation technology, doubling the
evaporation area and degassing time
2) Double stages vacuum source and dehydration, degasification
system, vacuum pump with roots pump, high speed vacuum evacuation,
ultimate vacuum ≤ 5Pa
3) Multi-stage precise filtration system with gradually increasing
precision, which can effectively remove mechanical impurities from
oil.
4) Advanced cooling system of vacuum pump, it reduces the frequency
of oil’s replacement and extends the life of vacuum pump.
5) 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.
6) Online oil treatment, vacuum drying and vacuum oil-filling for
electric equipments.
7) Automatic double-infrared liquid level controller, pressure
protector, which ensure long-term safely and reliable operation.
8) 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.
9) Automatic defoaming system with dual electronic monitoring
system, which avoid the foam ejecting and gushing to vacuum pump.
