Abstract

Use in hydraulic drives The essence of the invention in the housing (1) is a pump (2) A device (5) for controlling the flow of fluid is made in the form of a tank (7) installed in the lower part of the housing (1) with a cover (8) in a cut hole

Description

The invention relates to a hydraulic actuator, namely to hydraulic blocks

The aim of the invention is to prevent late / ha from entering the system.

In the drawing, a pre-constructive hydraulic tank diagram

The hydraulic tank contains a housing 1 with a pump placed in it (ohm 2 drain 3 and pressure 4 pipelines and a device 5 to control the flow rate of the fluid which is made in WIDD placed at the bottom of the hydraulic tank of an additional tank 7 with a lid 8 in which the hole 9 is made the pipe 4 is made of two parts 10 11 of the first (10) of which the pump 2 is bored with the additional tank 7 and ends inside it near the cover 8 and the second (11) is mounted on the vertical axis, but can be axially moved and reports the system 7 ( not shown) Bottom end 12 second cha

These 11 are placed at the bottom 13 of the additional tank 7, are made conical and form a choke 8 with the opening 9 of the throttle. Moreover, an electric motor 14 is installed on the hydraulic tank

The hydraulic tank works as follows.

A pump 2 driven by an electric motor 14 sucks the fluid directly from the lower part of the hydraulic tank and supplies it via pipeline 10 to tank 7 From tank 7, part of the liquid is sent to the system (not shown) via pipeline 11, and the rest of the liquid returns to the hydraulic tank ( pipelines 11 and the edge of the opening 9 R of the tank cover 8 8 When the pipeline 11 is lowered, the tazor between the conical part 12 of the pipeline 11 and the edge of the hole 9 in the cover 8 of the tank 7 decreases. As a result, the flow of fluid into the system increases and the

return of fluid to the hydraulic tank through the gap When lifting pipeline 11, increase i with the gap between its conical part 12 and the edge of the hole 9, which causes a decrease in fluid supply to the system with increasing return of fluid from the tank 7 to the hydraulic tank. In this way, the flow of the liquid is controlled.

In case the system continuously takes liquid from the hydraulic tank and does not return it back through pipeline 3, the liquid level decreases. When the liquid level drops to the lower edge of pump 2, the latter will begin to trap air and pump it into the pipeline. 10 A jet of liquid with air bubbles from the pipeline 10 directed upwards In the upper part of the tank 7, air is separated from the liquid. Air pushes the remaining liquid out of the gap between the conical part 12 and the edge of the opening 9 in the cover 8 of the tank 7 ivlenie in the gap decreases This facilitates the exit of all the air entering the tank 7 in a hydraulic reservoir and a reduction in the pressure

pipe 11 and the termination of the fluid supply to the consumer

Claims (1)

Claims of the invention A hydro-back containing a housing, a drain pump and a discharge pipe located therein and a device for controlling fluid flow including an adjustable choke characterized in that, in order to prevent air from entering the system, the device for controlling fluid flow is made as an additional one installed in the lower part of the housing a tank with a lid in which a hole is made; the pressure pipe is made of two parts, one of which communicates the pump with an additional tank with the placement end of the pipeline and the second side cover - is installed vertically with the possibility of axial movement and an additional tank communicate with the consumer while the lower end portion of the second discharge pipe is situated further from the bottom of the tank is conical and
