Description

(54) TANK

one

The invention relates to hydraulic systems of transport and mobile machines.

When the tanks are emptied, an axial gas vortex is formed above the olive nozzle, which penetrates the inlet to the transfer pump, disrupting its operation and large unused liquid residues.

There are known devices that allow leveling the fluid flow at the outlet of the tank, containing a plate or a conical lid, which is installed bottom up above the drain pipe 1 and 2.

The disadvantage of the device is the presence of additional resistance to the flow of liquid.

A known reservoir for storing liquids has a drain pipe and a cone mounted above it with a hole at the top, with a hollow rod connected to the base of the cone 3 vertically positioned on the wall of the tank above the drain pipe.

It is also known sedative device with a fuel pickup tube for a car’s fuel tank, made in the form

a cup having a vertical slot in the rear wall along the car, behind which, with a gap corresponding to the slot width, there are two vertical guides arranged in the plan below

5 angle to the axial longitudinal plane of the glass 4.

It is also known to have a device of similar purpose, comprising a drainage nozzle, provided with a conical cap, above

, Which is reinforced glass, set bottom up with the formation of a gap between the bottom of the tank and the edges of the open part of the glass, and at the bottom of the last hole 5.

However, the known devices do not allow the liquid in the tank to remain at the minimum acceptable level.

A known reservoir containing a soothing device with a fuel intake located in its closed housing.

20 tube. The case of the soothing device is formed by transverse partitions rigidly attached to the side walls of the tank and interconnected by an upper wall in which the breather tube is mounted, and parallel communication tubes are located in the lower part of the said housing, one end of each of which is led into the cavity of the tank and the other end is located with a gap relative to the partitions 6. Also known is a reservoir for a liquid, comprising a housing and an intake pipe with a confused nozzle, and in the lower part The intake pipe has at least one hole, the diameter of which is smaller than the diameter of the cross section of the intake pipe, and the confuser nozzle is made with flanging along the intake pipe to form a gap and with a hole in its upper part 7. These devices are effective when emptying the tank. in dynamic conditions with oscillations of the free surface of the liquid, when, when the liquid flows from the supply pipe, gas bubbles penetrate into it. Under conditions of stationary emptying of the reservoir, these devices lead to an increase in the residual liquid. In addition, they are: constructive in design and development. The closest to the invention in its technical essence and the effect achieved is a reservoir that includes a housing and a drain branch pipe vertically installed in its lower part with a funnel fixed above it 8. A disadvantage of the reservoir is the presence of a significant amount of liquid in the peripheral part of the container. In this case, the volume of non-flowing liquid residue is up to one second consumption. The purpose of the invention is to prevent gas bubbles from entering the drain pipe, increasing the reliability of the tank operation. This is achieved by the fact that in the tank containing the case and the drain branch pipe vertically installed in its lower part with the funnel fixed above it, the funnel carrier is made in the form of two hollow truncated conical nozzles coaxially mounted with a smaller base to the drain branch pipe coaxially to the latter and located in the central nozzle with a gap of the transverse partition, while the cross-sectional area of the smaller base of each nozzle is smaller than the cross-sectional area of the drain pipe. FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. 1. The tank contains a housing 1 with a drain pipe 2, a funnel 3 in the form of two hollow conical nozzles and a transverse partition 4. The cone with side slots is installed on two thin-walled ribs 5 and fixed to the latter with the help of angles 6. The transverse partition 4 is installed with a gap in the central nozzle and attached to the ribs 5 with the help of corners 6. Truncated conical nozzles 3 are installed with a smaller base to the supply nozzle. The height of the nozzles is chosen equal to the critical height of the gas vortex formed above the feed nozzle without installing a hopper above it. The size of the annular slots is chosen from the conditions for providing equal levels of liquid when emptying the reservoir. This is achieved by dividing the volume of the reservoir in the area of the funnel arrester in ratios that are equal to the ratios of the areas of the passage section between the nozzles themselves, the external nozzle and the reservoir according to a quadratic law. The movement of fluid from the central conical nozzle into the supply nozzle creates an ejecting effect on the outflow of fluid from the peripheral annular zones. To ensure this condition, the lower sections of the conical nozzles must be smaller than the supply nozzle. The volume of non-removable liquid residue at the time of gas inclusions in the supply port is approximately equal to the volume of the central conical nozzle. The use of the invention makes it possible to significantly increase the volume of liquid pumped from the reservoir and thus to increase the coefficient of its beneficial use. This saves the material of the tank, reduces the weight of the vehicle on which the tank moves, and reduces the cost of transporting it. Claims of the Invention A tank comprising a body and a drain branch pipe vertically installed in its lower part with a funnel fixed above it, characterized in that in order to prevent gas bubbles from entering the drain branch pipe the funnel carrier is made in the form of two hollow truncated conical nozzles coaxially mounted with a smaller base to the drain pipe coaxially last, and located in the central nozzle with a gap of the transverse partition, while the sectional area of the smaller base of each nozzle less cross-sectional area of the drain pipe.
