Abstract

The invention allows to intensify cooling and reduce the heat transfer of the working fluid in the hydraulic tank. Vertical partitions 4 are placed in the housing 1 equidistant side walls 2 with the formation of the drain and the internal intake cavities 5,6. The horizontal partition 9 is rigidly connected to the partition 4 and installed with a gap 10 relative to the bottom 3 with the formation of the inner tank 11. The drain nozzle 7 is installed vertically along the axis of symmetry and placed in the tank 11. The bottom 3 can be made in the form of a convex inside the sphere mating with walls 2 radius. The tank 11 is provided with an airtight cover 14. The cavities 5.6 can be combined and placed in the tank 11. The air gap 10 prevents heat exchange. 2 hp f-ly, 4 ill.

The invention relates to the field of hydraulic drive, and to the hydraulic tank

The purpose of the invention is to intensify the cooling of the working fluid and reduce the heat exchange of the working fluid.

The figure shows the design of the hydraulic tank with only vertical partitions; Fig 2 shows the same, with vertical and horizontal partitions; in fig. 3 - then. with a spherical bottom; fig A - hydraulic tank, reducing heat transfer.

The hydraulic tank contains body 1 with side walls 2 and bottom 3, a vertical partition 4 placed in Ifopnyce 1 equidistant walls 2 with the formation of a drain cavity 5 between the partition 4 and walls 2 and the internal intake cavity 6, the drain pipe 7, installed horizontally, and the suction pipe 8c. The hydraulic tank is equipped with a horizontal partition 9, rigidly connected with the vertical partition 4 and installed with a gap 10 relative to the bottom 3 with the formation of an internal tank I1, the drain branch pipe 7 is installed vertically along the axis of symmetry of the hydra The bottom of the hydraulic tank can be made convex inside the sphere 12, mating with the walls 2 radially 13 °. The internal tank 11 can be equipped with a sealed cover 14, and the intake 6 and the drain 5 of the cavity are combined and placed in internal tank 1 1 o

The upper section of the vertical septum is below the minimum allowable level of working fluid.

Hydraulic tank works as follows

The working fluid from the hydraulic system (not shown) enters through the horizontal drain pipe 7 (FIGURE 5) into the drain cavity 5, passes in the side beyond the mouth between the side walls 2 and the vertical partition 4, cooling down the path, n, reaching the upper edge of the vertical partition.

it is poured through it into the intake cavity 6, from where it passes through the intake pipe 8 into the hydraulic system.

. If there is a horizontal partition 9, the working fluid through the drain pipe 7 (figo 2 and 3) enters the gap 10 between the horizontal partition 9 and the bottom 3 and further along it into the side gap and through the upper cut into the intake cavity 6, This process is facilitated by the spherical shape of the bottom 3 and its junction with side walls 2 along radius 3c.

In the presence of a sealed cover 14, the working fluid is not cooled, the air gap between the inner tank 11 and the casing prevents the heat exchange.
