Abstract

The invention can be used for pumping liquids using solar energy. The aim of the invention is to provide heating of the pumped liquid and increase efficiency by more fully heating the working environment. The solar water lift contains a working 1 and pump 2 chambers separated by elastic elements 3 on cavities (P) 4, 5, 6, 7, while cavities 4, 5 are communicated by means of a tubular heat exchanger (T) 15 and filled with working medium, P 6 communicated with suction and discharge pipes 8, 9, the last of which is connected to T 16. P 7 is filled with a light boiling agent and contains a condenser 13, a heat absorbing panel 14. Solar radiation is heated by panel 14 and liquids in T 15 and 16. The boiling agent in П 7 evaporates, pressure in П 6 increases and pump EMA fluid via conduit 9 into the consumer in heated form. The absorption of the liquid in the P 6 is carried out during the condensation of the light boiling agent in the P 7. 1 Il.

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

The aim of the invention is to provide heating of the pumped liquid and increase efficiency by more fully heating the working environment.

The drawing shows a schematic diagram of a solar water lift, o25

The solar water lifter contains working and pumping chambers 1 and 2, each of which is divided by an elastic element 3 into two cavities and 5, 6 and 7, with one cavity k and 5 in each chamber 1 and 2 filled with working medium and communicating with each other, the second cavity 6 of the pumping chamber 2 communicates with the suction and discharge piping 8 and 9, equipped with check valves 10 and 11, the second cavity 7 35 of the working chamber 1 is filled with boiling agent and a section 12 of the discharge piping 9, where the condenser 13 is placed, is passed. Water lift The nickname is also provided with a heat-treating panel I and two tubular heat exchangers 15 and 16 placed on it, with cavities k and 5 filled with the working medium communicating with each other through one of the heat exchangers 15, and the second heat exchanger 16 is connected to the discharge pipeline 9.

The device works as follows 50 times.

In the initial position of the cavity 6 and 7, the heat exchanger 16, the pipes 8 and 9 are filled with the pumped liquid. Solar radiation heats the heat-absorbing panel b, the working and pumped fluids in heat exchangers 15 and 16. Heat from the working fluid

nel k. Solar radiation heats panel 1 and liquids in T 15 and 16. The boiling agent in P 7 evaporates, the pressure in P 6 increases and the pumped liquid through pipeline 9 flows to the consumer in a heated form. The absorption of the liquid in the P 6 is carried out during the condensation of the light boiling agent in the P 7. 1 Il.

through the elastic element 3 in the chamber 1 is transferred to the low-boiling agent in the cavity 7, heats it, as a result of which the pressure in the cavity 7 and, consequently, in the cavity 6 increases and the pumped liquid through the valve 11 enters the consumer in a heated state. When a colder liquid begins to flow from the cavity 6 into the condenser 13, the low-boiling agent in the cavity 7 begins to condense, the pressure in cavity 7 and, consequently, in cavity 6 drops and a new portion of the pumped liquid enters chamber 2 through valve 10. The pump cycle is repeated.
