Description

Yo

The invention relates to a pump construction and can be used to drive hydraulic motors into rotation, as a jet engine of a boat or boat.

A known pump containing a heat pipe, a heat source, arranged to supply heat to the upper part of the heat pipe, a refrigerator located in the lower part of the pipe, a suction and discharge line with non-return valves, an axial bypass channel with a non-return valve connecting the suction line to the annular channel made in the upper part of the pipe and communicated through an opening with the internal cavity of the pipe.

The disadvantage of the pump is its low efficiency and mosh, due to the fact that in the process of displacing the liquid from the heat pipe, part of the steam formed during heating

the upper part of the pipe condenses on the mirror of the displaced fluid.

The purpose of the invention is to increase the efficiency and productivity of the pump

The goal is achieved in that the pump is additionally equipped with a float disk separator located in the cavity of the heat pipe with a small radial clearance, the upper end of the float-separator is made concave, the above- and sub-float volumes are connected by a float valve, the seat of which is located above the valve and connected to the bottom point of the concave end of the float separator, in the upper part of the pipe, a profiled cover convex towards the separator is coaxially fixed with the possibility of matching with the surface of the separator elitel, while an additional bypass channel is installed in the pipe wall with

in it at the inlet and outlet, respectively, by float and check valves, and drain holes are made in the upper part of the pipe with the possibility of communicating the internal cavity of the pipe with the discharge line with an additional bypass channel.

The increase in power (efficiency) and efficiency of the pump is achieved due to the fact that the float separator located in the cavity of the heat pipe, when suction is under the surface of the liquid irrigating the pipe wall through the holes of the annular cavity, and does not reduce the condensation surface, but when the liquid is displaced into the discharge the line is located above the surface of the displaced liquid and therefore there is no process of vapor condensation on the mirror of the displaced liquid, which allows to increase the number of displacement cycles in a unit tsu time.

The drawing schematically shows a pump.

The pump contains a heat pipe 1 filled with pumped liquid 2, with a heat source 3, connected through a backwater valve 4 to the outlet line 5 of the pumped liquid 2 and through a check valve 6 with a hydraulic accumulator tank (not shown conventionally), refrigerator pipes 7, a check valve 8, located in the channel 9, passing through the refrigerator 7, connecting the annular cavity 10 with the holes 11, which open onto the inner surface 12 of the upper part of the heat pipe 1, with a hydraulic accumulator tank.

The pump is equipped with a float disk separator 13, located in the cavity of the heat pipe with a small radial clearance, with a concave upper surface 14. The float separator 13 is equipped with a float valve 15 with a seat 16 located above the valve 15, connecting (separating) the above- and sub-float volumes , and connected to the lower point of the concave end 14 of the float separator 13. The pump is further provided with drain holes 17 located above the holes 11 of the annular cavity 10 in communication with the cavity 18, which channel 19 contains the float valve 20 sequentially located in it, the float of which is located above the seat 21, and the non-return valve 22, is connected to the output line 5, in the upper part of the pipe, a profiled cover 23 is convexly convex towards the separator side and can be mated with the surface

separator 13 made of a material with low heat capacity and thermal conductivity.

The thermal pump operates as follows.

When exposed to the heat pipe 1 by the heat source 3, part of the liquid 2 in its upper part evaporates, displaced by the float separator 13

0 liquid from bottom pipe 1 through valve 4 to consumer. During the fluid displacement process, the float valve 15 remains closed provided that the buoyancy force of the fluid acting on the valve 15 is closed.

5 is more than the product of frictional force between the float separator 13 and the inner surface of the pipe by a coefficient formed by the ratio of the area of the seat 16 to the cross-sectional area of the float separator 13. When the liquid 2 is displaced by the float separator 13, the valve 15 opens, steam enters the cavity under the float separator 13 where. partially condensed on the mirror of the displaced liquid 2, it displaces it through the valve 4 to the consumer. After all liquid 2 is displaced from the pipe 1 to the consumer, the steam is condensed by the refrigerator 7. The vapor pressure in the pipe 1

0 decreases and valve 4 closes. After reducing the vapor pressure in the pipe 1 to a pressure lower than in the hydraulic accumulator tank, the check valves 6 and 8 open and the liquid 2 begins to fill the pipe 1. while the float valve 15 closes.

When liquid 2 enters the pipe 1 through the valve 8, it passes through the channel 9 through the refrigerator 7, cools, enters the annular cavity 10 through the holes 11, cooling the inner surface 12 of the pipe 1, intensifying the process of steam condensation. The liquid 2 entering the pipe 1 through the holes 11 of the stack

5 of the surface 12, fills the concave surface 14 of the float 13, increasing the surface of the vapor condensation. Under the action of liquid 2. entering the pipe 1 through the opening valve 6, the float divider 13 moves upward, accumulating liquid 2 from its openings 11 from the openings 11, which then drains through the openings 17 into the cavity 18, and the float valve 20 opens . At

5, as the float separator 13 moves further upward, the liquid filling the volume formed by the concave surface 14 is displaced by the coaxial and mating surface 23 into the upper part of the pipe for evaporation. The displaced liquid surface 23 is vaporized and displaced through the open valve 20 through the channel 19 through the check valve 22, the liquid 2 from the cavity 18 to the consumer.

After all liquid has been expelled from the cavity 18, the valve 20 closes by shutting off the channel 19, and the cycle repeats.

Compared with the prototype, the proposed pump has a higher productivity due to the intensification of the displacement and absorption cycles, a greater efficiency of the use of thermal energy.
