Description

The invention relates to elements of a power supply system for carburetor engines mounted on gas trucks, buses, construction and road machines, river boats, stationary installations and aggregates.

The purpose of the invention is to increase the efficiency of gasoline cleaning.

FIG. 1 shows the proposed main filter-settler gasoline, the cut; in fig. 2 - magnetic trap; in fig. 3 - the same, top view.

The gas filtering tank contains a metal housing 1, in the center of which the central rod 2, the wing 3 with the inlet and outlet holes and the clamping bolt 4 are welded. A sealing washer is installed between the head of the bolt 4 and the cap. An adapter 6 is installed, on which the magnetic trap is fixed, consisting of a lower cup 7, a permanent ring magnet 8, an insulating strip 9 and an upper cup 10.

Glasses 7 and 10 are made of magnet of a soft material.

A disk 11 made of a solid dielectric is installed on top of the magnetic trap. Inside the housing, a filter element 12 is mounted on the central rod 2. The design of the filter element may be different. For example, a plate filter element consisting of a large number of brass plates with a thickness of 0.14 mm can be installed in the filter sump. The plates are assembled on two heels and clamped by a spring 13 between the washer 14 and the plate bS.

At the same time, the spring 13 presses the filter element 12 in the assembly s of the filter mat. There are a large number of embroidered protrusions with a height of 0.05 mm on the filter plates. Due to these protrusions between the plates, gaps equal to said protrusions are formed. plate 5 and lid 3 put a cardboard gasket 16, and between the case 2 and lid 3 put the pasp

Here, due to a drop in the speed of gasoline, the largest particles that clog up it are deposited, which pass through the cutouts in the bottom glass 7. Thus, the lower part of the filter housing is also a settling tank, and the magnetic trap acts as a sedative, which contributes to better gravitational settling. mechanical contamination and free water. Further, the passage between the pole tips, gasoline is freed from ferromagnetic particles that accumulate in the gas tank in the result of corrosion of the gas tank surfaces.

At the same time, the trapping of light non-magnetic contaminants occurs, which, under the influence of molecular forces, agglomerate around the iron particles and together with them are attracted to the pole tips of the magnetic trap. In addition, under the influence of magnetic flux

Each fine particulate matter coagulates to form sludge, which deposits in the lower part of the sump filter housing.

Thus, partially cleaned gasoline passes through the gaps between the plates of the filter element, finally released from contamination, enters the chamber above the filter element and through the outlet in the pipeline to the gasoline pump.

The main filter of the sump is equipped with a contamination indicator, for which a circuit consisting of a constant resistor 21, an LED 22 and a power source 23 is connected between the pole tips of the magnetic trap. When iron particles accumulate between the pole tips, a circuit closes, as indicated by the LED 22. The glow of the LED depends on the degree of overlap of the gap between the pole tips.

Care of the filter in the water outlet and mud from the settling tank, as well as in the washing of the filter element and the magnetic trap.
