Abstract

The invention relates to compressors with a hydraulic drive operating under the action of a hydrostatic pressure, and makes it possible to increase the reliability of the operation of the compressor. The compressor housing 1 consists of a spherical upper chamber (K) 2 and a lower K 3 communicated with it by means of a nozzle 11. In the upper K 2 there are suction and discharge valves 4 and 5 and an elastic separation membrane 17 with a rigid center 18 is fixed. The membrane 17 separates the upper K 2 to the supramembrane gas and submembrane hydraulic cavities. The rigid center 18 is secured with a flexible ha ha 19, with the other end secured to the stem 10. The stem 10 passes through the nozzle 11 and is fixed to the shut-off organ 9 of the drain float valve 8 located in K 3. In K 3 there is also a fairing-clamp 20 fixed on the guide 21 of the rod 10, the inlet and outlet nozzles 6 and 7 for the supply and discharge of fluid. The guide 21 is fixed in the pipe 11, and the fairing-latch 20 is installed on the side of the inlet pipe 6 to protect the closure member 9 from the dynamic effect of the incoming fluid and ensure its stable position. An additional container 12 is connected to the pipe 11 with a float valve 13 for periodically introducing and releasing air into the K 3 and thereby ensuring reliable operation of the compressor. The presence in the construction of the membrane 17 makes it possible to obtain and direct compressed air to the consumer without the admixture of water vapor, which leads to corrosion of the duct line and pneumatic equipment. 1 hp f-ly, 3 ill.

The invention relates to compressor building and can be used to supply pneumatic equipment with compressed air in the automation of hydro-ameliorative production processes in mountainous areas using hydrostatic water differential.

The purpose of the invention is to increase reliability.

FIG. 1 shows a compressor at the moment of filling with a liquid; in fig. 2 - the same, completion of the injection process; in fig. 3 - the same, the beginning of the process of suction.

The compressor includes a housing 1 consisting of an upper spherical chamber 2 and a lower chamber 3. In the upper chamber 2, there are suction and discharge valves 4 and 5. In the lower chamber 3 there are inlet and outlet 6 and 7. Outlet 7 It contains a discharge valve 8 with a valve 9, which is made in the form of a float. The flow sections of the pipes 6 and 7 are selected in such a way that the volume of the incoming liquid through the pipe 6 is slightly less than the volume of liquid flowing through the pipe 7. The locking member 9 has a rod 10, the upper chamber 2 communicates with the lower chamber 3 through the pipe 11. The rod 10 is located in pipe 11, the Compressor is equipped with an additional tank 12 with a float valve 13, having

there is a shut-off organ in the form of the float 14 and an outlet 15. The additional container 12 is connected by a pipe 16 to a branch pipe 11. The upper chamber 2 is provided with an elastic membrane 17 with a rigid center. 18. The hard center 18 is connected to the stem 10 by means of flexible pulling. 19. The locking member 9 is provided with a fairing-lock 20 located on the side of the inlet manifold 6. The stem 10 is installed in a guide 21 fixed on one side to the fairing-lock 20, on the other hand, in the pipe 11 using a perforated partition 22, the rod 10 has a stop 23. In the upper chamber 2 there is a decompression device made in the form of a two-armed lever 24, at one end of which a valve 25 is fixed. Pressure line 26 contains a safety valve en 27

The compressor works as follows.

The fluid through the inlet manifold 6 continuously enters the lower chamber 3. At the initial moment, the stop valve 9 of the drain float valve 8 interrupts the outlet manifold 7. As the chamber 3 is filled, air is displaced from the chamber and removed through the pipe 16 into the container 12 and then through hole 15 to the atmosphere. As the chamber 3 is further filled, the pipe 16 is filled with water and begins to supply water to

bone 12 until it fills it, and float 14 does not block opening 15. The air from chamber Z is completely removed, the elastic membrane 17 lies at the bottom of chamber 2, and the hard center 18 is on the perforated partition 22,

With a further increase in the level of the liquid, it enters the upper chamber 2 under the membrane 17, compresses the air above the membrane 17 under the action of the pressure of the liquid. Compressed air is displaced through the discharge valve 5.

The rigid center 18 of the elastic membrane 17, having reached the location of the lever 24 of the decompression device, acts on it by opening the valve 25, discharging the residual compressed air into the atmosphere. At the same time, the flexible ha ha 19 is still not fully stretched. The pressure in the supramembrane cavity of chamber 2 decreases to atmospheric. Next, the flexible rod 19 is fully expanded and raises the rod 10c by the locking member 9, the liquid exits through the outlet 7, and the membrane 17 is lowered due to the fact that the fluid inflow through the inlet 6 is less drained through the outlet 7, the valve 25 locks. When this occurs, air is sucked through the suction valve 4 into the supramembrane cavity of chamber 2, the locking member 9, which is a float, rises and abuts against the radome-fixer 20, where it is held in the upper position by lifting force. The membrane 17 with a rigid center 18 is lowered into the lower part of chamber 2. The restriction of the gel 23 prevents the flexible rod 19 from entering the lower chamber 3,

A decrease in the level of the liquid leads to the opening of the float valve 13, and a further decrease in the level occurs as a result of the flow of atmospheric air into the chamber 3. The shut-off member 9 overlaps the drain valve B, stopping the discharge of the liquid. A safety valve 27 is installed on the discharge line 26 in order to prevent water from entering the injection system in the event of possible damage to the elastic membrane 17. Next, the process of operation of all elements

cops of the compressor is repeated in the sequence described,

Thus, the presence in the construction of a separating elastic membrane 17 makes it possible to increase the reliability and durability of the elements of the injection system, duct lines and pneumatic equipment, as it prevents compressed air from being saturated with water vapor. The presence of an additional tank 12 with a float valve 13 is necessary for the normal operation of the compressor with a separator

5 by means of a membrane 17, ensuring periodic inlet and discharge of air from the chamber 3 therefrom, and the presence of a skirt-latch 20 and a guide 21 of the rod 10 contributes to a stable reliable process of lifting, lowering and holding in the upper and lower position of the locking member 9, protected from dynamic flow. water flowing through the pipe 6, the spherical shape of the upper chamber 2 ensures a tight fit of the membrane 17 to the inner surface of the chamber. The advantages of this compressor are also small

Q energy consumption, since the structure does not require a pump unit with an engine, control valves, and can operate under the action of a static water differential automatic.
