The invention relates to a pump engineering turn out, in particular, to the design of hydraulic Taranov, and can be used in the design and manufacture of water-lifting devices in the system of land reclamation and water management without additional energy sources to supply air to the air cap of hydracarina.

Air-hydraulic pumping bell hydracarina is an inherent characteristic of transient operation modes, the causes of which is the vacuum ejected passive medium in the form of air flowing in the inlet pipe section.

Known hydropneumatic Taran containing working chamber with shock and discharge valves, the main air cap with the discharge pipe and check valve and the tank, which has a penstock (USSR Author's certificate No. 1328588, CL F04F 7/02, 1987).

A disadvantage of the known hydro-pneumatic ramming is the lack of coherence of the drum and discharge valves, as when water hammer occurs, the reflected shock wave, propagating along a feed line leading to reduced reliability because of the frequent change of compression and re-opening shock valve when there is a spring that causes it to break it and replace the last.

The main disadvantage is that you use the compress is R to supply compressed air into the hood. However, their performance may be far greater than the air leakage in the water supply when the water lift to the consumer. It is clear that their application will not be economically justified. However, you have to constantly replenish this process in the hood by air, in the absence of this action is productivity and efficiency.

Also known an air cap of hydracarina with supply air, which consists in the fact that the air cap with the inlet valve and the air inlet hole connected to the air supply in the housing cover (USSR Author's certificate No. 1224464, CL F04F 7/02, 1986).

A disadvantage of the known device with artificial recharge of the air cap on the ultra-high pressure compressor runs through the spiral tube and is mainly used to move the piston in the housing hydracarina, and the air space between the piston and the liquid is not filled with air. Hence part of the energy overhead is lost in the hydraulic shock to lift the fluid from the horizon in the case of the air cap. Therefore, proposed artificial recharge compressor through a spiral tube in the lid. However, the compressor will not be economically justified, which leads to higher operating hydracarina.

An overall review of the operation of the ode pumps on the principle of action shows what should be the exchange of energy between the fluid and the provision of ejection passive medium (air).

The objective of the invention is to improve the performance of hydracarina.

To solve the problem in the way of pumping air into an air cap of hydracarina, namely, that in an air cap serves the air, the air supplied into the working chamber section of a feed line provided with an air cap, and control the flow of air passing through vozduhovodnogo tube, one end of which is reported with the active nozzle of the working chamber and the other with the atmosphere, and in the moment of achievement of specified volume of air in the cap corresponding to the pressure mode, the air supply is stopped, and the air source are in the form vozduhovyvoda camera, which report to the working chamber and through the venting tube having an Executive block valves, air cap, and the end of the feed pipe fitted in front of the hood.

The technical result is achieved due to:

- use the mixing chamber, providing site vozduhovyvoda camera;

- there is a relationship between the Executive unit and the cap is based on the joint work of the mixing chamber and vozduhovyvoda camera.

This way p is dicki air pulses increases the coefficient of ejection and improves the performance of hydracarina, i.e. with mandatory periodic pumping in air cap air. Pumping air by using the fluid inlet into the mixing chamber, is provided by the ejection passive environment (atmospheric air). At this time, due to the expiration of the fluid pressure before the nozzle falls, then the fluid and the flow of air under pressure to the pipeline enters vozduhovyvoda the camera down the pipe and connected with the air cap through the venting tube having Executive unit with valves and pressure sensor. The air pressure sensor is installed on the housing in the upper part of the air cap. When applying air control sensor air pressure in the cap. Based on these indications, in each moment of time determine the amount of fill air in the cavity of the cap through a controlled valve in the venting tube. Thus, the air volume increases, and automatically updates the necessary volume of air after depletion hydracarina that eventually he begins to work in more efficient water lift fluid and increases productivity in extended use of hydracarina. With a sharp rise in pressure in the surge and the filling liquid of the hood, through the check valve, the air is compressed and dampens the increase is Alenia in the cap. Pumping atmospheric air by the proposed method significantly simplifies the design of hydracarina and its operation. Automating the control valve using the Executive block air flow through vozduhovyvoda camera feed line, one can assume that such a device will find application in practice. Therefore, the lack of use of the compressor for pumping air into the hood will be economically justified.

Thus, a new technical solution is less expensive, reliable and does the job hydrant with high efficiency.

The device has a linear arrangement, due to the binding to the hydraulic Taran.

In Fig. 1 presents a schematic diagram of a method of pumping air into an air cap of hydracarina; Fig. 2 shows a diagram of hydracarina, General view.

The method of pumping air into an air cap of hydracarina contains the supply pipe 1 and the drain pipe 2, the first of which has a working sections 3 and 4, each connected to the air cap 5 and 6, provided with discharge valves 7 and 8, the working parts of the pipes 3 and 4 contain transitional pipe with active nozzles 9 and 10 respectively with the working chambers 11 and 12, the latter is communicated with the atmosphere through vostokovednyh tubes 13 and 14 with non-return valves 15 and 16, and the valve is and 17 and 18, communicated with the atmosphere. Working chambers 11 and 12 are connected by pipes 19 and 20 in the form of a cone with the air source, made in the form vozduhovyvoda cameras 21 and 22 on the outlet conduits 23 and 24, connected to the branch pipes 25 and 26 embedded in a sealed enclosure 27. Vozduhovyvoda cameras 21 and 22 is communicated with the air caps 5 and 6 through the venting tubes 31 and 32, with the Executive unit 33 and 34 slavename 35 and 36. In the upper part of the caps 5 and 6 installed pressure sensors 37 and 38 associated with the air cap.

Curved shock valves 28 and 29 are made of sheet metal with rubber gaskets including the axis of the actuator 30 to rotate the actuator. The control mechanism includes a bottom dual console lever 39, to the shoulders which are attached to the levers 40 and 41. The levers 40 and 41 pivotally connected with the rods 42 and 43, pivotally connected to a top dual console lever 44, is placed on the axis 45 of rotation which is fixed to the rotary knob 46 with the latch, for example, in the form of a locking screw (not shown). On the cover 47 of the sealed enclosure 27 is made of the recesses 48, corresponding to the number of positions at the overlapping sections of the outlet pipes 25 and 26 with a curved shock valves 28 and 29. Each nozzle 25 and 26 from the outer side has the tabs 49 and 50, the profile of which is curved shock Klah is Anu and shifted by the amount in accordance with the size of overlapping holes of the nozzles 25 and 26.

Air caps 5 and 6 are equipped with bypass valves 51 and 52 and also connected vodopodayuschih pipes 53 and 54 through a pipe 55 with the water tank 56.

Additionally it can be installed remote-control actuator for remote control of the pivoting handle 46 mounted between the electromagnets (not shown for simplicity).

The method of pumping air into an air cap of hydracarina works as follows.

If according to the reading of the sensor 37 are created conditions for the emergence and continued existence of the pressure mode, for example, in the cap 5, in the initial state when the flow of fluid in the delivery pipe 1 and through the working area 3, including transitional pipe with nozzle 9, the camera 11, the pipe 19 in the form of a diffuser and then through the discharge conduit 23 water transit flows through the outlet pipe 25 in a sealed casing 27 and the drain pipe 2. The liquid passing through the transition tube with the active nozzle 9 into the chamber 11, and then goes into the pipe 19 in the form of a cone, mixed with atmospheric air through the provision of ejection passive environment (atmospheric air) and the expiration of the fluid pressure in the chamber 11 falls in front of the nozzle 9 (increases the size of the working vacuum, the check valve 15 is opened and atmospheric air enters the chamber 11, two input of the camera 11 is formed by vacuum, and the device starts to work when opening the valve 17. Air from the atmosphere is sucked into the working chamber 11 and the flow of fluid through the pipe 19 of the diffuser fluid enters vozduhovyvoda the camera 21 and the air accumulates in the upper section of the chamber 21, which contributes to the shape of the chamber through the venting tube 31 via the control unit 33 to open the valve 35 to the venting tube 31 and carry out air supply, for example, in an air cap 5, with the result that it is pumping air to the design pressure detected by the sensor 37 pressure. After filling air to the design pressure of the Executive unit 33 sends the command to close the valve 35 to the venting tube 31 and stops the flow of air in the upper part of the cap 5 detected by the sensor 37 pressure, resulting in the latter is ready to receive fluid when creating a surge in the working area 3, due to the closure of the shock valve 28 is formed hammer. With increasing pressure fluid through the discharge valve comes in one of the air boxes 5, which ensures the conservation of the air in the cap of the hydraulic RAM. Formed an air cushion, which occurs due to compression of the additional accumulated atmospheric air and emitted from the liquid, i.e. the additional the additional stored energy of the air in the cap 5 starts to operate in a more efficient mode hydraulic RAM for the supply of liquid in the water tank 56 of the consumer at a higher height.

After work one of the air boxes 5 hydraulic RAM, in the same sequence continues in the second air cap 6, i.e. the working cycle is repeated. This Executive unit 34 with valve 36 in the venting tube 32 is included in air cap 6.

The air supply pipe 19 or 20 in the form of the diffuser mixing provides increased accumulation in the upper section vozduhovyvoda chambers 21 or 22 ready air pump for air boxes 5 or 6 using the Executive blocks 33 or 34 with the valve 35 or 36 on the venting tubes 31 or 32, respectively, defined by the pressure sensors 37 or 38.

The intake and compression of air in the caps 5 or 6 can be a very effective way paging atmospheric air in the caps 5 and 6 hydracarina. An integrated approach in the work of the hydraulic RAM is to establish the peculiarities of the functioning of the elements of the device in one unit and coordination of site works by using the control unit, improving performance and reliability of hydracarina.

Application of the proposed method of pumping air into an air cap eliminates an additional compressor and complexity in its use economically mode RA is the notes of hydracarina.
