Abstract

The invention relates to mechanical engineering and m. used when pumping fluid (L) with an increased range of generated head. The invention makes it possible to increase efficiency by increasing the generated pressure. When the tank Z is filled (E) I1, the latter increases in volume under the action of P16 its elastic wall unbalanced pressure W 12. This pressure is transferred to the elastic wall 17 of the pumping chamber (K) 16 filled with the pumped G, with the help of rigid links 18. An increase in pressure in E M causes stretching of its walls and walls 17, as a result of which 20 energy is stored in them. When the unbalanced pressure WI2 decreases, the capacitance P and K16 are compressed under the action of the elasticity of their walls, and the elastic forces of the wall E1I are transmitted to the wall 17K16 using straps 18.

And: the invention relates to mechanical engineering, namely, methods for converting thermal energy into mechanical energy, can be used for pumping fluid with an increased range of generated pressures, as well as for charging medium pressure gas-hydraulic accumulators using low-potential thermal energy, including natural temperature differences between liquid media, and is an improvement of the method according to ed. St. No. 1216420.

The purpose of the invention is to increase the effect of genesis by increasing the generated pressure.

FIG. shows a device for carrying out the inventive method in a position where one of the working chambers and the working fluid in it are cooled in a lower position when in contact with a liquid cooler; FIG. 2 shows the same device in a position where another working chamber and the working fluid in it are heated in the lower position when in contact with a heated heat-transfer fluid; on fig.Z - elastic capacity of variable volume with a pumping chamber placed inside, section.

The device for carrying out the proposed method contains two working chambers 1 and 2, respectively, heated and cooled, partially filled with working fluid 3, for example aqueous ammonia, interconnected by fluid-like 4 and located on opposite arms of the rocker arm 5. Heated chamber 1 is installed above heated liquid coolant 6, and the cooled chamber 2 - above the liquid cooler 7. In the heated chamber 1, an elastic film 8 is provided with a container 9 of variable volume connected by pipeline 10 with an elastic tank 1I of variable volume mounted on the opposite arm of the rocker arm 5. The tank 9 and 11 and the pipe 10 are filled with an additional unbalanced fluid 12. The pipe 10 is rigidly connected to the fluid 4 by links 13. The heated heat-transfer fluid 6 is separated from the liquid cooler 7 by thermally insulating wall 14, which is installed

on the axis 15 of the rocker 5. In the elastic tank 11 there is a pump chamber 16 formed by an elastic-elastic wall 17 connected

rigid brackets 18 are connected to the wall of the elastic container 11, through one of which the pumping chamber 16 is hydraulically connected to the pumping line 9, and through the other to the suction pipe 20, and a check valve 21 is installed in the pipe 19, open from the side of the chamber 16, and line 20 has a check valve 22, open from the side of the suction line 20.

When implementing the proposed method, the device operates as follows.

Chamber 2, together with the working fluid 3 filling it with an aqueous solution of ammonia, is cooled in a lower position when chamber 2 is in contact with a liquid cooler 7 (Fig. 1). When cooled, the solubility of ammonia in water increases, and the aqueous solution absorbs ammonia, as a result of which the pressure in chambers 1 and 2 decreases, and the additional unbalance fluid 12 moves through conduit 10 from elastic tank 11 to reservoir 9. At the yoke 5, due to redistribution of fluid 12 between the capacitors 11 and 9 creates a moment of weight unbalance, under the action of

5 of which the yoke 5 rotates around the axis 15. The cooled chamber 2, located on the left, moves to the upper position, rising above the level of the liquid cooler 7, and the heated chamber 1 — to the lower position, plunging into the heated coolant 6 (Fig. 2). The working fluid 3 through the fluid line 4 is discharged from chamber 2 into chamber 1, to the right. Chamber I, together with the working fluid filling it with a 3 - aqueous solution of ammonia, is heated in the lower position when the chamber 1 contacts the heated liquid coolant 6.

When heated, the solubility of ammonia in water decreases, and gaseous ammonia is released from the water-2 solution, as a result of which the pressure in chambers 1 and 2 increases, and the unbalanced volume 12 moves through conduit 10 from tank 9 to tank 11. On a yoke 5 of -behind

the reverse redistribution of the fluid 12 between the containers 9 and 11 creates a moment of weight unbalance in the opposite direction compared to the moment of unbalance in the preceding phase of the process. The beam 5 is rotated around the axis 15 in the opposite direction by the action of the weight unbalance, and the device returns to its original position shown in Fig. 1, after which the process is periodically repeated.

When the elastic tank 11 is filled, the latter increases in volume under the effect of an unbalanced fluid 12 on the elastic wall. This pressure is transferred to the elastic wall 17 of a smaller area located inside the tank 11 and the pump chamber 16 filled with the pumped liquid by means of connecting tank 11 and the chamber 16 rigid links 18.; Due to the fact that the wall area of the container 1 1 ci1; is naturally larger than the area of the wall 17 of the pumping chamber 16, the pressure in the container I1 causes the wall of the container I1 and the wall 17 of the chamber 16 to stretch, resulting from the valve 20 through the valve 22 to the chamber 16, the pumped liquid is sucked. At the same time, when the wall of the container 1I and the wall 17 16 in them are stretched, the energy “energy” is determined, which is determined by the elastic forces of the walls of the vessel 11 and the chamber 16. With a further decrease in the pressure of the unbalanced fluid 12. the capacitance 11 and the chamber 16 are compressed by the action of the elasticity of their walls, and the elastic forces of the wall I-1 are transmitted to the curtain 17

chambers 16 using rigid connections 18. When the pumping chamber 16 is compressed, the pumped liquid is pumped out of it through the valve 21 5 into the pressure line 19.

A decrease in the suction pressure in the pump chamber 16 and an increase in the discharge pressure therein as compared with the minimum and maximum

0 by pressure in an elastic tank 1 1 is achieved by transferring through rigid ligaments 18 pressure acting on a large area of the wall of the tank 1 1 to a smaller area of the wall 1 7

 5 chambers 16. Increasing the discharge pressure provides a more efficient use of the proposed method when converting low-potential mechanical energy

20 heat.
