COMPLEX OF FILTERS FOR CLEANING OF DIELECTRIC LIQUIDS Russian patent published in 2020 - IPC B03C5/00 

FIELD: cooling; engines and pumps.

SUBSTANCE: invention relates to cleaning of liquid dielectrics, preferably, turbine, fire-resistant, transformer, aircraft and hydraulic oils. Complex comprises a percolation-aspirating drier with the possibility of supplying dried air into the inner part of the oil tank, a droplet separator filter, coarse filters, one of which is installed behind the pumping in pump, and second is behind oil tank of percolation-aspirating drier, with filtration fineness exceeding previous coarse filter, packets of electrostatic filters of super deep purification, installed in turns, inside which focusing electrodes are arranged in parallel, percolation-aspiration drier tank is fitted with a centrifugal fan with a coalescer filter in front of the air dryer, and inside the oil tank of the percolation-aspirating drier level transducers are arranged to switch off the pumping in pump and switch on the pumping out pump motor.

EFFECT: increased safety of operation, increased service life of oils, ensured energy saving.
