The invention relates to pumps for pumping liquids direct impact on her compressed or rarefied environment, in particular to the submersible borehole pump installations.

Primarily the invention can be used in industry for the removal of liquids from great depths, such as from wells, and to restore the muddy wells.

In addition, the device can be used for sampling of groundwater from monitoring wells placed in the field and located on the perimeter of the underground oil storage or burial of waste, in particular radioactive.

The prior art downhole pneumatic pump that contains a camera replacement with intake and discharge pipes, are provided with check valves, and the gas pipeline which is connected with a source of compressed gas from the nozzle of the ejector (see USSR author's certificate No. 1622641, CL F 04 F 1/02, 1987). Above the downhole pump was received by the applicant for the prototype.

For reasons that impede the achievement of specified following technical result when using the known pump, taken as a prototype, is that the pump is only designed to remove liquid from the wells, and when they are silting up of the recovery wells is carried out with the use of other devices, which for example washing, in the case of selection of the wells of a representative sample distorts their reliability.

In addition, the known device is designed in such a way that its application leads to increased consumption of compressed gas, as it requires a constant depending on the ejector, which is problematic in the field, when the pressure source used compressed gas cylinders.

The purpose of the invention is improving the performance of downhole pneumatic pump in the field by expanding its functionality and reducing the consumption of compressed gas.

The technical result - the combination of multiple functions in one device, allowing the field with the same equipment (proposed downhole pneumatic pump) to produce as the removal of groundwater from wells, and restore them from silting up without the use of additional wash water, thereby passing another technical result - reliability analysis of representative samples taken.

This technical result in the implementation of the claimed invention is achieved by the well known pneumatic pump comprising a camera replacement with intake and discharge nozzles, each of which is provided with a check valve, and is also the pipeline, reported with camera replacement and a source of compressed gas, and the ejector with the active nozzle peculiarity lies in the fact that the discharge nozzle attached to the discharge piping with shutoff valve, and the nozzle is placed directly inside the chamber substitution, which is additionally mounted removable nozzle with the possibility of replacing the cap, and the gas pipeline connected to the system supply and distribution of compressed gas and, as the discharge line is made of separate parts fastened together by means of the quick connection.

In addition, the feature of the pump in a particular case is that the system of supply and distribution of compressed gas supplied shut-off valves with high-speed drives and to control the actuator isolation valves pump contains an electronic unit with a programmable microcontroller and the operator panel, which is connected to the onboard network of the vehicle.

Installation of discharge piping with shutoff valve on the discharge pipe, is placed inside the chamber of substitution, which is equipped with a removable nozzle, helped to wash away the silt and restore the well without the use of additional wash water, thereby increasing the degree of reliability of the analysis is taken to depict Avialinii samples and use in the field of only one type of equipment. The production pipeline and the discharge of separate parts fastened together by means of the quick connections allowed to change their length depending on the depth of the well and to reduce the consumption of compressed air.

Install shut-off valves with quick drives in the system of supply and distribution of compressed gas allows not only to alternate the flow in camera replacement vacuum from the ejector and pressure from a compressed gas source, but also produce a flow of compressed gas to the active nozzle of the ejector periodically.

So the supply of compressed gas to the active nozzle of the ejector is not produced by compressed gas in the chamber substitution when the displacement of the water and when the water level in the well, enough to fill the camera replacement under the hydrostatic pressure of the water column in the well. This allows to reduce the consumption of compressed gas, thus increasing the efficiency of the pump.

The supply pump electronic control unit with a programmable microcontroller and operator panel connected to the vehicle electrical system, allows you to change the duration of the feed-in camera replacement vacuum and compressed gas within wide limits and apply the proposed pump in wells of different depths, which significantly expands the functionality of the performance communications capabilities of the pump.

Information confirming the ability of the invention to provide the above technical result are as follows.

Figure 1 shows the pneumatic pump figure 2 - diagram of the operation of the system of supply and distribution of compressed gas.

The proposed downhole pneumatic pump includes camera replacement 1, which contains the inlet 2 and the discharge 3 nozzles, are provided with check valves 4 and 5 respectively. To the intake pipe 2 connected grid 6, and to the discharge pipe 3 to the discharge pipe 7, in the upper part of which is mounted a shut-off valve 8. On the bottom of the camera replacement 1 set of removable nozzle 9 (a), instead of which it can be installed cap 10 (option B). Luggage replacement 1 reported through pipeline 11 from the supply system and distribution of compressed gas 12. The pipeline 11 and the discharge pipe 7 is made of flexible tubes, which after a certain period connected with quick couplings 13, which allows you to set the optimum length of the pipeline 11 and the discharge pipe 7, depending on the depth of the well. Luggage replacement 1 is supplied by a cable 14, is wound on the winch drum 15 with a flexible gas line 11 and the discharge pipe 7. The pipeline 11 connect the n to the system of supply and distribution of compressed gas 12, communicating with a compressed gas source 16 and the ejector 17, by means of a quick coupling 13. The system of supply and distribution of compressed gas 12 contains three shut-off valve with quick-acting actuators 18, 19 and 20, are installed on the pipeline 21 compressed gas from source 16 into the pipeline 11, line 22 supply of vacuum in the pipeline 11 from the ejector 17 and the pipe 23 for supplying compressed gas from a compressed gas source 16 to the active nozzle of the ejector 17, respectively. The operation of high-speed drives shut-off valves 19, 20 and 21 is carried out automatically by an electronic control unit 24 containing a programmable microcontroller and the operator panel.

Pump operation is as follows.

Depending on what operation is planned in the well, the camera replacement 1 is installed or removable nozzle 9, if there is a recovery wells from siltation or cap 10, when performed removal of ground water from it. Camera replacement 1 is lowered into the borehole by means of a winch 14 on the drum which is wound the cable 13, the discharge pipe 7 and the gas pipeline 11. After a dive camera replacement 1 into the borehole to the desired depth of the pipeline 11 and the discharge pipe 7, is wound on the winch drum 14, is separated parts thereof nearest astronishing connections 15 and join the system of supply and distribution of compressed gas 12 and the shut-off valve 8, respectively. On the operator panel of the electronic control unit 24 connected to the onboard network of the vehicle, set the duration of the cycles of filling of the chamber substitution 1 water and its displacement from the camera 1. By pumping of groundwater from the well and start the pump with electronic control unit 24 opens the shutoff valves 19 and 20. While on active nozzle of the ejector 17 is supplied compressed gas, and the camera replace 1 of the ejector 17 and the pipeline 11 is vacuum. Luggage replacement 1 through the check valve 4 is filled with water within a specified time, after which the shutoff valves 19 and 20 are closed, and opens the shut-off valve 18. In camera replacement 1 from a compressed gas source 16 through the pipeline 11 is supplied compressed gas and an exclusion of water through the check valve 5 into the discharge pipe 7 and further to the surface through the open shut-off valve 8.

When restoring muddy wells in the chamber 1 instead of the stub 10 is installed removable nozzle 9, the check valve 8 is closed. In this case, water from the chamber substitution 1 is displaced by the compressed gas back into the well, diluting the sludge deposits. For pumping formed by the erosion of silt in the well suspension periodically open the stop valve 8, when opened, water from the chamber substitution 1 is displaced at the same time and in the nozzle 9, and the injection pipe 7.
