Device for supplying water from the well
(57) Abstract:Device for supplying water from the well relates 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 with pressure pipe installed device hydroplane in the composition of the housing and the inflatable chamber, and the case of the adaptation of hydroplane made in the form of upper and lower flanges on which are mounted respectively the upper and lower rims of the inflatable chamber, provided with a nipple. In the cavity of the inflatable chambers on the lower flange of the body has a bellows cavity through which the drains are connected with the cavity of the discharge pipe. This eliminates the possibility of contamination of the inflatable chamber and to extend the period of operation of the device without prophylaxis its devices hydroplane. 2 Il. The invention relates to devices and mechanisms for exploitation of groundwater sources and intakes, in particular for pumping of artesian water in Magistralnaya 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 losses, reduction of the supply pressure and the 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 prevent damage when removing the device from the well.The technical task of isoa task is solved by in the known device, comprising a pump with a pressure pipe, is installed on the device hydroplane in the composition of the housing and the inflatable chamber, the case of the adaptation of hydroplane made in the form of upper and lower flanges on which are mounted respectively the upper and lower inflatable rims camera with nephalem in the cavity of the inflatable chambers on the lower flange of the body has a bellows cavity through which the drains are connected with the cavity of the discharge pipe.In Fig. 1 shows the device when installed in the borehole of 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 corps, made in the form of upper and lower flanges 5 and 6, and an inflatable chamber 7 with nephalem 8 in the cavity where the bellows 9 is connected via a drainage 10 with a cavity pressure of the pipeline.The device operates as follows.Before installing the unit in the casing 1 artesian wells the pressure in the cavity of the inflatable chamber 6 to fit the C drainage systems 10 static pressure P1water in section 4 the discharge pipe 3, the ends of the bellows 9 depart from the upper flange 5 of the housing at the maximum possible distance (Fig. 1).After you install the device in the hole and turn on pump 2 volumes of the bellows 9 under the action of pressure P2water pumped from the aquifer wells, reach a maximum value. Extending to the contact of its ends with the upper flange 5 of the bellows 9 increase the pressure Po in the cavity of the inflatable chamber 7 to a value of Px, under which the walls of the chamber 7 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, the volume of the bellows 9 is reduced and porom restored clearance with the casing pipe 1, for a smooth lifting device from the well.However, dirt and sand that enters the device hydroplane during the peak moment of switching on of the pump 2 and t on the walls of the water passages 10 and is washed away when you turn off the pump 2 water filling the bellows 9.Thus, the proposed device allows you to completely eliminate the possibility of contamination of the inflatable chamber and, thereby, increase the periods of operation of the device without prophylaxis its devices hydroplane. Device for supplying water from a well that contains a pump with pressure pipe installed device hydroplane in the composition of the housing and the inflatable chamber, wherein the case of the adaptation of hydroplane made in the form of upper and lower flanges on which are mounted respectively the upper and lower rims of the inflatable chamber, provided with a nipple in the cavity of the inflatable chambers on the lower flange of the body has a bellows cavity through which the drains are connected with the cavity of the discharge pipe.
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.

FIELD: water intake structures, particularly obtaining and confining water by means of pit wells.
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. Connected to disc valve is air-tight removable plug having cable fastened to the disc valve to provide manual valve opening in the case of valve seizure. Pipe with water displacement valve is installed in the casing pipe and extends for the full casing pipe length. The pipe has check valve and shutoff valve located at well outlet. Method for water production from artesian well with the use of above device involves filling casing pipe with water portion under dynamic artesian horizon level pressure; activating compressor; filling the receiver with compressed air; supplying compressed air into casing pipe under pressure corresponding to summary height of well and water tower; displacing water from casing pipe into water tower; closing compressed air inlet valve; venting air from casing pipe through pressure relief valve, which is closed after air discharge operation termination and continuing above filling-displacement operations.
EFFECT: increased reliability and pressure without the use of submersible pump provided with electric motor.
