The invention relates to devices and mechanisms for exploitation of groundwater sources and intakes, in particular for pumping artesians the water from the well, containing the discharge pipe and the pump with gear shaft [1].

However, the presence of the gear transmission in the known devices leads to a large volume loss, reduced feed pressure and efficiency of the pump.

Closest to the proposed to the technical essence and the achieved effect is a device for pumping water from a well, comprising a pump with a pressure pipe, is installed on the device hydroplane in the composition of the housing and the inflatable chamber, the cavity of which is connected with the pressure pipe through the drain [2].

In the known device the available devices hydroplane allows to increase the production of the well. However, during operation of the device in the cavity of the inflatable chamber there are deposits of fine sand (the "pestovania" wells) and dirt falling into the well during installation and maintenance works, and in the cavity of the inflatable chamber is at the next turning on the pump. This can lead to what is generated when you turn off the pump the gap between the walls adfilternone tube wells and inflatable chamber is insufficient to exclude povrezhdeniya contamination devices hydroplane.

This task is solved in that known device, comprising a pump with a pressure pipe, is installed on the device hydroplane as part of the hull and inflatable chambers, equipped with a bellows placed in the bellows chambers, General upper flange bellows cameras mounted on the lower end of the body devices hydroplane, the internal cavity of the bellows through the exhaust vents in the specified case is connected with the cavity of the inflatable chamber and the cavity of the bellows chambers through the discharge connected with the cavity of the discharge pipe.

In Fig. 1 shows the device when installed in the well; Fig. 2 - the device is in working condition.

The device is located in the casing pipe 1 artesian well and contains the pump 2, the pressure line 3, the partition walls 4 which has the device hydroplane in the composition of the housing 5 and the inflatable chamber 6. On the lower end of the housing is mounted bellows chamber 7, the internal cavity of the bellows 8 in which through the duct 9 is connected with the cavity of the inflatable chamber. Cavity bellows cameras through drainage systems 10 are connected with the cavity of the discharge pipe.

The device works by Slavnoi camera 6 devices hydroplane is brought to a value of P0in which, despite the opposition through drainage systems 10 static pressure P1water in section 4 the discharge pipe 3, the ends of the bellows 8 will depart from the casing 5 at the maximum possible distance (Fig. 1).

After you install the device in the hole and turn on pump 2 bellows 8 under the action of pressure P2water pumped from the pump layer of well compacted and through exhaust vents 9 increase the pressure P0in the cavity of the inflatable chamber 6 to a value of Pxunder whose walls are specified camera will cover the gap with casing pipe 1 (Fig. 2).

After a moment of overlap of the specified gap further the balance between the volume pumped into the distribution network of water and its volume flowing into the casing 1 from the aquifer will be reduced when compared with the atmospheric pressure on the surface of the water in the well, causing additional water inflow, i.e., increases production of the well.

When you turn off the pump 2 by lowering the excess pressure in section 4 discharge pipe 3 to a value of P1and under the action of pressure Pxin the inflatable chamber 6 volume placed in C is of Pxthe original values of P0where is restored clearance with the casing pipe 1, which provides smooth lifting device from the well.

When this dirt and sand that enters the device hydroplane during the peak moment of switching on of the pump 2, and Asagaya on the walls of the water passages 10 and is washed away when you turn off the pump 2 water filling the bellows chamber 7.

Thus, the proposed device allows you to completely eliminate the possibility of contamination of the inflatable chamber, and thereby to increase the periods of operation of the device without prophylaxis its devices hydroplane.
