SU1212491A1 - Installation for cleaning oil - Google Patents

Description

The invention relates to the manufacture and operation of hydraulic systems and lubrication systems for machines and units and can be used in the operation, maintenance and repair of automobiles, tractors, road machines and other equipment ..,:

The goal of this is to extend the cpo.ka of the tree and improve the quality of the purified asla.

The drawing shows an installation for the purification of oil, the technological scheme. The installation contains a drain device G, which serves to drain the oil from product 2, tank 3, divided into three sections: primary, intermediate and cleaned oil section, communicating with each other via overflow valves 4 and 5 with the possibility of oil overflow only in the direction from sections of purified oil to the primary section. The oil is circulated using a two-piece pump 6, the higher capacity section of which, with the coarse filter 7 connected in series, the magnetic filter 8 and the dispersant 9, forms an oil coarse purification system, and the lower section with a centrifuge 10, fine filter 11, meter 12 concentration of mechanical impurities and bypass valve 13 form a closed system of fine cleaning. The meter 12 concentration of mechanical impurities is connected to the secondary device 14 by an electric cable.

The discharge piping section of higher performance of the pump 6 and the suction piping of the section of smaller capacity are separated by a shut-off valve 15.

On the suction pipe of the lower capacity section, a check valve 16 is installed.

Flushing and filling the hydraulic system or the lubrication system of the product 2 is performed through a shut-off pipe 27, closed by a valve 18.

A flow meter 19 is installed on the drain line to control the volume of oil poured when refilling the product.

The installation works as follows.

From the product 2, the oil through the drain device 1 is discharged into the primary section of the tank 3. At the same time, the pump 6 is turned on, the larger section of the pump 6 pumps the oil to the intermediate section of the tank 3 (shut-off valve 15 is closed). At the same time, the oil passes through a coarse filter 7, where particles of mechanical impurities larger than 20 µm are retained, a magnetic filter 8 that retains ferromagnetic particles and a dispersant 9 built into the lid of section B of the tank 3 disintegrates the precipitated crystals of the additive substance and releases the adsorbed on particles of mechanical impurities.

When the oil level in the primary section of the tank 3 decreases, as it is pumped to the intermediate section, the overflow valve 4 opens and part of the oil from the intermediate section is poured into the primary section, thus the established minimum oil level is maintained in the primary section.

After filling the section B of the tank 3. The stop valve 15 is opened, then the oil after the magnetic filter 8 is divided into two streams: part of the oil through the disperser 9 is discharged into the intermediate section of the backspace 3, the other part is directed to the suction side performance of the pump 6, the feed oil in the centrifuge 10 and the filter 11. It is a thin cleaning, where particles of mechanical impurities with a size of 2 microns and more are deposited.

After cleaning in the centrifuge 10 and fine filter 11, the oil passes through the meter 12 concentration of mechanical impurities, then through the check valve 13 (valve 18 is closed) is discharged into the section 3 of purified oil of the tank 3. Due to the difference in performance of the pump section 6 with the shut-off valve open 15, a back pressure is created in front of the check valve 16, and oil does not flow from the purified oil section of the tank 3 to the suction line of the lower pump capacity section. The check valve 16 prevents the drain into the section of the purified oil of the tank 3 of oil that has not been cleaned in the centrifuge and the fine filter.

When the oil level drops in the pump 6, the centrifuge 10 — the intermediate section of the tank 3 opens — the fine filter 11 — measures the overflow valve 5 and a portion of the maximum 12 mechanical concentration from the purified oil section — the overflow valve 13 - pours into the intermediate section. 5 section of the purified oil of tank 3 until the arrangement of valves 4 and 5 is high until it is reached, they provide maintenance in s-necessary for further operation of the intermediate and primary oil basation cleaning it up 3 a certain minimum urs-torus is controlled by indications m n masla.10 secondary device 14.

After installation in the sections of the lane-flushing and filling the hydraulic system

primary and intermediate stable or lubrication system 2 is produced
