Abstract

The invention relates to devices for purifying hydraulic and dielectric fluids (oils and fuels) of mechanical impurities and dissolved and dispersed water. It could be used in any fields where clean and contaminated fluids are used. The apparatus for reclaiming hydraulic and dielectric fluids comprises a vacuum tank with an atomizer, a vacuum pump, a dielectric fluid feed pump and dielectric fluid removal pump, all of said pumps being connected to the tank by pipes, and an electric filter, wherein the atomizer is disposed in the lower part of the vacuum tank, is arranged vertically with a spray member oriented upward and consists of a T fitting with a lower inlet for fluid and with a lateral inlet for air, a mixing chamber disposed above the T fitting, and a spray member with a nozzle, said spray member being disposed above the mixing chamber, and the electric filter comprises a housing with an inlet pipe and outlet pipe, a high-voltage power supply, a composite unit disposed inside the housing and consisting of current-carrying plates and dielectric spacers with apertures for current-carrying and heavy-duty fastening elements, a front plug and rear plug, and is current-carrying and heavy-duty fastening elements, wherein the surface of the current-carrying plates is provided with a porous ceramic dielectric coating. The technical result is increasing the efficiency of purifying and reclaiming dielectric fluids; increasing the useful volume of the vacuum tank without increasing the dimensions thereof; reducing the dispersivity of the fluid sprayed from the atomizer; simplifying the design; stabilizing the electromagnetic field of the electric filter; increasing the surface area of the electric filter by creating a developed surface of current-carrying filter elements without changing filter size and mass; improving reliability and ease of use; and reducing materials consumption.

Abstract

The invention relates to methods for operating apparatus for purifying hydraulic and dielectric fluids. The apparatus of interest is activated in an automatic mode, frequency converters and the level of oil in a tank are checked, a vacuum pump is switched on, and air is pumped out of the vacuum tank. If the vacuum is not satisfactory, the apparatus is switched off, the integrity of the pneumatic system is checked, and a return to a baseline algorithm is effected. A feed pump is switched on and initial filling of the tank is carried out. If the tank is not filled to the necessary level, the apparatus is switched off, the integrity of the hydraulic system is checked, and a return to the baseline algorithm is effected. Next, the working of a discharge pump is checked. When a given fluid level is reached in the tank, the discharge pump is switched on in a self-adjusting mode. The stability of the apparatus in terms of certain parameters is checked, electric filters are switched on, and a normal operating mode for maintaining the parameters is activated. After all of the fluid has been pumped out of the tank, the discharge pump is switched off, the vacuum pump is switched off, and the electric filters are switched off. This increases the fail-safety of the apparatus, and provides a simple and accurate operating algorithm.
