(57) Abstract:Water-lifting device refers to devices and mechanisms for exploitation of groundwater and water intake structures, in particular for pumping of artesian water in the main line of urban water systems. The device includes a pump, discharge pipe and the device hydroplane as part of the hull and inflatable chamber, an upper rim which is mounted on the upper flange of the body, and the sump, allowing to greatly reduce the degree of contamination of the inflatable chamber and clogging sand it. The sump is made in the form tapering to the bottom of the Cup and is installed on the delivery pipe with the observance of the gap between the upper flange, which is the number of the through holes, and the case of the adaptation of hydroplane. The lower rim of the inflatable chamber is mounted on the top flange of the tank and the discharge line is equipped with water taps in the cavity of the tank. The technical result of the invention is to increase the time of operation of the device without prevention devices hydroplane. 2 Il. The invention relates to devices and mechanisms for e trunk line urban water systems.Known water-lifting devices containing discharge pipe and the pump with the transmission shaft (Shabalin, A. F. Operation of industrial pipelines. - M.: metallurgy, 1972, S. 143).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 water-lifting device containing the pump, the pressure line and the device hydroplane in the composition of the housing and the inflatable chamber, the upper and lower rims of which are mounted respectively on the upper and lower flanges of the housing and the cavity is connected with the pressure pipe through the drain (SU authorship, 1044741, class E 03 B 3/08, 1983).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 when the next turn is electicheskie work devices hydroplane.An object of the invention is to increase the time of operation of the device without prevention devices hydroplane.This task is solved in that the water-lifting device containing the pump, the pressure line and the device hydroplane as part of the hull and inflatable chamber, an upper rim which is mounted on the upper flange of the body, included the sump, made in the form tapering to the bottom of the Cup and mounted on the delivery pipe with the observance of the gap between the upper flange, which is the number of the through holes, and the case of the adaptation of hydroplane, the lower rim of the inflatable chamber is mounted on the top flange of the tank and the discharge line is equipped with water taps in the cavity of the tank.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 well and contains a pump 2, section 3 the discharge pipe 4, on which is mounted the device hydroplane in the composition of the housing 5, the inflatable chamber 6 and the sump 7. The upper flange 8 of the sump contains a number of through holes 9. GNC/P> The device operates as follows. The assembled device is lowered into the casing 1 to a predetermined depth (Fig. 1). When turning on the electric pump 2 water under pressure, which occurs in section 3 of the pipe 4, through the outlets 10 begins to enter the cavity of the tank 7. After filling the tank 7 water through a series of holes 9 of the upper flange 8 and the gap between the said flange and the housing 5 is supplied into the cavity of the inflatable chamber 6 and extends all the way to the wall of the casing 1 wells (Fig. 2). As a result, further balance between the volume of pumped water and the volume of water 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. This causes an additional inflow of water, i.e., increases production of the well. In this case, the dirt that enters the device hydroplane during the peak moment of switching on of the pump 2, and the sand (when the device is in "pesquisa" well), will settle mainly on the walls of the sump.When you turn off the pump 2 by lowering the excess pressure in the delivery pipe 4 volume inflatable chamber 5 decreases to the original value (f is becoming water-lifting devices sump 3 allows comparison with the prototype significantly reduce the degree of contamination of the inflatable chamber 6 and the driving of the cavity with sand and thus, to increase the periods of operation of the device without prevention devices hydroplane.Sources of information:

FIELD: obtaining or collecting drinking water or tap water, particularly to wash artesian wells along with flow rate and specific flow rate determination.
SUBSTANCE: method involves supplying compressed air in water lifting pipes of airlift with mixers arranged at different levels; blocking water flow in hoses and feeding compressed air to mixers through separate hoses. At the beginning of above operation compressed air is supplied to upper mixer and then in water lifting pipes. Airlift is brought into stable operational mode. Compressed air is fed in downstream mixer and operation is provided by two mixers. Then upper mixer is switched off or kept in operational state.
EFFECT: increased efficiency and extended range of technology methods.

SUBSTANCE: water production device comprises casing pipe provided with disc valve and with perforated filter arranged in lower part thereof. Upper casing pipe part has steel bottom with pressure relief valve adapted to reduce pressure inside casing pipe and compressed air inlet pipe having valve. The valve is connected with receiver and with air compressor.

SUBSTANCE: water-intake tubular well comprises a perforated casing pipe in soil arranged with its perforated section in a water-bearing layer of rocks, and a water-lifting device in it. At the upper end the casing pipe is equipped with a cover with a collar installed on it, on the cord of which there is a water-lifting pipe suspended. The water-lifting pipe has an injection valve at the lower input and a circular body along the casing pipe diameter with a suction valve and elements of hydraulic seal along the external diameter in the form of circular grooves. To drill a water-intake tubular well, a device is used, which comprises drilling pipes and a cutting drilling bit. The drilling bit is equipped with a container with a valve made of light material, for instance, plastic, to stock damaged rock. Drilling pipes are lighter pipes, for instance, water-gas pipes. On the upper end of drilling pipes there is a transverse lever of rotation. In case of high drilling depth a device is used for lowering and raising operations, including a clamp of drilling pipes and a support for clamp placement. The support is made in the form of a well head with openings of trapezoidal shape on the upper end. The clamp is made of one movable and one fixed halves with a tightening bolt and radial levers laid into openings of the well head.
EFFECT: increased height of water raising from a water-intake tubular well.
