Deep Vacuum Oil Purification System UVM-6

UVM-6 (capacity:
- in the degasification, heating, filtration mode - 1.0 m3 per hour
- in the heating and filtration mode - 1.4 m3 per hour).

The system are used for thermal vacuum degasification, azotizing, drying, heating and purification
of transformer, cable, turbine and other oils for removal of gases, free and soluble water and
particulate matter. The system is applied while installation, repair and operating of oil-filled high-
voltage equipment up to 1150 kV (power transformers, high-voltage switches etc.) as well as
turbines.
The system can be exploited for heating of oil-filled units with hot oil and for vacuumizing of power
transformers.
The system consists of two isolated sections: the oil section and vacuum section interconnected
with a vacuum conductor.
The oil section is intended for degasification and removal of mechanical impurities, azotizing,
heating and pumping of oil. The oil section corresponds to a metallic, heat-insulated box wherein
are located a vacuum column, oil heater-filter, receiver, oil inlet and output pumps, absorptiometer
with a vacuum pump, fine filter and pre-filter, control cabinet, stop and control valves, oil pipelines
and vacuum conductor. The absorptiometer allows to perform a rapid analysis of residual gas
content in the oil. The section operational parameters are controlled by temperature regulators
with a sensor, vacuum control device with lamps, pressure-and-vacuum gages. Electrical circuit
provides for switching off the system in case of the oil flow’s absence, oil heater’s overheating
(with providing of a sound signal), short circuit protection, improper phase interlacing prevention,
phase breakage protection. Processed oil’s temperature is maintained automatically.
The vacuum section is intended for exhaust of air, non-aggressive gases and vapor previously
cleaned of condensed moisture and particulates out of insulated vacuum units, particularly out of
the vacuum column of the oil box. The vacuum section corresponds to a metallic box with a
concreted bottom wherein are located vacuum units, an oil pump, axial blower, heating element, a
tank with heaters, control cabinet, vacuum connector with a non-return valve, compensator, fly gate,
vacuum meters. The vacuum section’s parameters are controlled by the vacuum meters,
temperature regulators. The electric circuit is protected in the same manner as in the oil section.
There is a possibility provided for the oil’s process along closed cycle. The three-stage filtration
system enables to process a good amount of oil until scheduled removal of filter elements.
The oil degasification is put into effect in the thermal vacuum manner along with spraying in the
vacuum column. The oil is directed by the oil pump into the oil heater, after being heated and
clarified from particulates the oil moves to the vacuum column wherein it is sprayed and trickles
down along the inlet fittings. Tickling along the inlet fittings the oil forms a thin tape, owing to this,
gases and moisture intensely vaporize. The vacuum in the column is maintained with vacuum
pumps which provide removal of gases and moisture through the receiver. The degasified oil is
directed through the fine filter system into the transformer.

The system operates in four modes
- heating and filtration
- degasification and filtration
- pumping and filtration
- azotizing and filtration


UVM-6 model consists of one section wherein oil and vacuum unit are combined.

We are the manufacturer ofvacuum oil purification systems for cleaning, vacuum degasification, filtration, regenerationand drying transformer, insulation fluid and turbine oil.The equipment is designed for both regenerating of oil for transformer under repair, and for processing of new insulating oil before its initial filling into the transformer.Also we are looking for dealer in your region
