SU1728535A1 - Water-lifting device - Google Patents

Abstract

The invention relates to pumping engineering, can be used for pumping various liquids, and allows to expand the scope of application by allowing the creation of a vacuum. The water-lifting unit contains a working chamber 6 in the form of a tank-cylinder 3, a thermally insulated bellows 2, valves 1, 4.5, liquid 6 and gas 17 capacitors. When steam enters inside the bellows 2, the latter displaces the liquid from the tank-cylinder 3. After that, the steam in condensers b and 17 condenses. The vacuum formed in the capacitance-cylinder 3 can be used for pumping out a liquid or evacuating the receiver 22. 2 cpff, 1 sludge.

Description

The invention relates to a technique which is intended for raising water and obtaining a vacuum used in folk households, in particular in agriculture for milking cows.

Devices are known, in particular, a solar water lift containing an elastic-elastic tank, a steam heater, and receiving cylinders.

The well-known solar water lift has steam losses as well as a low operating cycle (L).

The aim of the invention is the wide economically and environmentally beneficial use of water vapor in the national economy and the possibility of additional vacuum generation without special re-equipment of the installation.

This is achieved by the fact that a thermally insulated bellows, a combined condenser and a low pressure receiver are built into the tank, the cylinder.

The drawing shows the proposed installation.

The installation contains check valves 1.4, thermally insulated bellows 2, tank-cylinder 3, discharge valve 5, water-cooled condenser 6, condensate collection compartment 7, water collector 8, suction lines 9,12,19, suction valves 10, 18 tank 11, 13-16, 20 — valves, air-cooled condenser 17, capacitor capacitance 21, low pressure receiver 22.

The cavity of the thermally insulated bellows 2 is connected by pipeline to the check valve 1, and through the check valve 4 to the coil center of the combined condenser 6 and 17. The tank-cylinder 3 is connected through the valve 15 and the suction valve 18c to the cavity of the receiver 22 and on the other side the tank-cylinder 3 is connected pipe 19 through the discharge valve 5 with the reservoir 11. And then the tank-cylinder 3 is connected to the pipeline (L

House 19 through the valve 20 of the pipeline 12c condenser, with a capacity of 21. The suction valve 10 of the pipeline 9 - with a water intake 8. The upper end of the condenser coil 17 is connected to the valve 13, and the lower end of the coil 6 of the condenser tank 21 - with a compartment 7 for condensate collection, which is connected to the valve 14.

The installation works as follows.

The bellows 2 and the condenser 17 are filled with steam. To do this, the valves 13 and 14 are opened and the check valves 1 and 4 are turned on. When the bellows 2 and the capacitors B and 17 are filled with steam, the valves 13 and 14 are turned off and the check valve 1 is turned off, stopping the steam supply. Next, after condensing the steam in condensers 6 and 17 and bellows 2, the resulting vacuum in the cylinder tank 3 is filled with atmospheric pressure water from the water intake 8 through line 9 to the suction valve 10. condenser tank 11 (where will enhance condensation in the water-cooled condenser 6 ) pipe 12 valve 20 pipe 19. After filling, the check valve 4 is turned off. In this preparation for work on the rise of water and vacuum is complete.

Installation on the rise of water works as follows. The check valve 1 is turned on - the steam enters the cavity of the bellows 2, displaces water from the cylinder-cylinder 3 through the pipeline 19 and the discharge valve 5 into the tank 11. After the displacement, the check valve 1 is turned off and the check valve 4 is turned on. The steam from the bellows 2 through the check valve 4 enters the condenser b where it is intensively condensed, forming a vacuum in the cylinder tank 3.

Then, at atmospheric pressure, water flows from the water intake 8 through conduit 9 through suction valve 10 to condenser capacitance 21. where it cools the coil b and through conduit 19 enters reservoir-cylinder 3. Then the cycle repeats.

The operation of the apparatus for producing a vacuum is as follows.

The valve 20 overlaps and the valve 15 opens. Check valve is activated

1, steam enters bellows 2, displaces atmospheric pressure through conduit 19 and discharge valve 5 to atmosphere. After the bellows 2 is filled, the steam supply is stopped. The check valve 1 is turned off and the check valve 4 is turned on. The steam from the bellows 2 enters the air-cooled condenser 17, where it condenses to form a vacuum, which is filled with residual atmospheric pressure from the receiver 22 through the suction valve 18 and the valve 15 into the cavity of the tank-cylinder 3 .

Then the cycle repeats, the condensate in the vertically located coil b and 17 flows into the compartment 21 where it accumulates and

is removed through valve 14. Through valve 16, a vacuum is used in milking, drying and other apparatuses.
