ZYD Multi-functional Transformer Oil Vacuum Reusing Purifier
Double stage vacuum transformer oil reclamation machine, high vacuum purifying and regenerating process, saves money
Introduction:
Series ZYD Double-stage Vacuum Transformer Oil Purification System is used for transformer oil dehydration and transformer oil degasification as well as other electrical insulating liquids such as silicone fluids.The ZYD Process is able to increase and maintain oil's dielectric strength and includes the removal of free and soluble water,free and dissolved air and gases and other particulate matter.The standard ZYD system is designed for processing oils in workshops ,in storage tanks or directly in transformaers(energized or de-energized transformers).Series ZYD oil purifier can be used as an independent vacuum source with functions of vacuum drying and vacuum oiling.
Features:
1.ZYD can evacuate the vacuum for the electric equipments separately, such as the transformer. Also it
can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum
state.
2.This machine have two vacuum pumps (one is the vacuum pump, other one is the roots pump), which
can improve the working value highly. Making sure the water-content of the treated oil is less than 3 ppm.
3.The machine adopts the double-infrared liquid automatic controller,pressure automatic protector which
can make sure the machine works online for 150 hours continuously without person. So it is a reliable
and high automatically machine.
4.Besides the common vacuum oil purifier's function of dewatering, degassing, and removing the impurity
, this machine can regenerate the seriously bad oil by separating the electric-polarity materials, such as
deeply oxides and free carbon from the oil effectively. The treated oil can reach the specifications of the
new oil, such as the oil dielectric strength, flash point, acid value and oxidation resisting etc.
5 Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
6.Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
7.Adopt interlocked protective system, which connect 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.
8. Functions of live line work onsite, vacuum drying and vacuum oiling.
Optional Features:
An exhaust condenser to measure the extracted water
Condenser is equipped to settle the most volatile oil fractions which might distil back to the column
Digital temperature measurement
Digital precision vacuum gauge
Digital flow meter
Digital in line moisture content meter
Ionic reaction columns to remove the acidity from the oil
Audio / Visual fault annunciation System
PLC control system
Mobile Trailers can be provided
Fully-enclosed and Semi-enclosed for weather-proof are available
