Abstract

The invention can be used to pump various fluids. The aim of the invention is to increase the operational reliability by automating the launch. The water lift contains a collector-evaporator 1 with inlet and outlet nozzles 2.3, an injector (I) 4, a starting tank (PE) 11, two controlled distribution valves 12, 13, the first of which is controlled by pressure in the zone of the inlet section of the chamber mixing (CS) 14, installed in the suction line 9, and the second, controlled by pressure in the area of the output section of the COP 14, - in the hydraulic line 6, with the PE 11 communicating with the suction line 9 through the valve 12, and the hydraulic line 6 communicating with a reservoir 10 through the valve 13. At start-up, the liquid supply opens Spins from PE 11 to collector-evaporator 1 and I4, and with sufficient pressure drop in the inlet area of KS14, valve 12 shuts off the flow of liquid from the PE 11 and opens it from the reservoir 10. When the operating pressure in the area of outlet K14 is reached, valve 13 switches the liquid to drain in a reservoir 10 and opens its giving to the consumer. 1 il.

The invention relates to the field of pump construction and can be used for pumping various liquids using solar energy.

The purpose of the invention is to increase the operational reliability by automating the launch.

The drawing shows a schematic diagram of the water lift.

The solar water lifter contains a collector-evaporator 1 with inlet and outlet nozzles 2 and 3 and an injector, the output 5 of which is connected by a hydraulic line 6 to the consumer and the inlet nozzle 2, the steam nozzle 7 with the output nozzle 3, and the liquid nozzles 8 by means of the suction line 9 - with a reservoir 10. The water lift is also equipped with a starting capacity of 11 and two controlled distribution valves 12 and 13, the first of which, controlled by pressure in the inlet area of the mixing chamber 14 of the injector k, is installed in the suction line 9, and the second control a detectable pressure in the output chamber cross section area of mixing 14 - in the hydraulic line 6. The launch container communicates with the suction -11 piniey 9 through the first control valve 12 and hydraulic line b communicates with the reservoir 10 via the second control valve 13.

Water lift works as follows.

On a start command, the fluid supply from the starting tank 11 to the collector-evaporator 1 and through the valve 12 to the injector 4 is opened. The evaporated liquid in the collector-evaporator 1 accelerates the s injector 4. Pressure

in the area of the inlet section of the mixing chamber 14 of the injector 4 falls, and when it reaches its operating value, the valve 12 shuts off the flow of liquid from the starting tank 11 and opens the flow from the reservoir 10. The pressure in the output section of the mixing chamber 14 of the injector 4 grows and when the operating pressure is reached, the valve 13 switches the flow of the pumped liquid from the drain into the reservoir 10 to the flow to the consumer.
