Abstract

The utility model relates to a double-pipe artificial laminated pump which belongs to an elastic fluid pump. The utility model is characterized in that an elastic laminated pipe the end covers of which are sealed is adopted as a working component, and controls and achieves the functions of fluid-medium suction and discharge when the laminated pipe with the property of variable volume is matched with a one-way valve. The working process of the utility model is identical with that of a cylinder plug of a plunger pump. The utility model has the advantages of no energy loss of sliding friction, good gas tightness and high mechanical efficiency. The utility model can be applied to artificial tap water supply, irrigation, spray and air inflation.

Description

Double-conduit artificial complex pump

The utility model belongs to elastic fluid pump by international classifiation.

China's people in the countryside are numerous, and are sparsely populated, and power supply guarantees that degree is low, and most urban residents adopt the water intaking of hand well, and domestic water is still carried the cylinder storage on the shoulder.Hand well cylinder, plug sliding friction resistance are big, and the piston rod reciprocating stroke produces the factors such as energy loss, gas leakage of throw of eccentric to making its mechanical efficiency low in addition; Adopt centrifugal pump or submersible pump to supply water and be subjected to power supply, hole diameter condition restriction, still need and set up water tank, spending is big.

The purpose of this utility model is: from economic, practical angle, improve the deficiency of aforementioned two kinds of water lifts technically, to improve manually aquation from the beginning of urban residents' living water condition-realization; The solution groundwater resources amount is few, is not enough to the drought resisting and the part irrigation problem of supporting exploitation water-deficient area, and even realizes drawing water, inflate, spraying the purpose of a tractor serves several purposes.

Model utility is achieved in that and adopts the elasticity stacked tube that is loaded with the sealing of one-way valve two end cap, is equipped with one-way valve control with its variable volume characteristic, finishes suction, current drainage body medium function; Its work efficiency is equal to the cylinder plug of plunger pump.Change the original structure of cylinder plug, solved consume of piston and casing wall frictional resistance and sealing problem.Only overcome sliding friction and promptly improve mechanical efficiency 20-80%.Adopt two joint connecting rods to be connected the throw of eccentric that produces with in the elimination spring tube stroke between cylinder cap and transmission levers.Manually to be power, not limited by Power Supplies Condition.Extract the underground water of buried depth, settle planted agent's valve down, the corresponding prolongation pump housing greater than 9m; Perhaps gas injection is with raising of water level in well as tracheae with one in two stacked tubes, and the influent stream pipeline of another pipe is extended down to below the water level.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the sectional drawing of two-tube artificial laminated pump.

Below in conjunction with accompanying drawing structure, working procedure and the performance of model utility are done with explanation.

This pump is by being that symmetry, identical two-part are formed with the lever central shaft, but single tube works alone.The main body of pump is elasticity stacked tube (1), two ends are O RunddichtringOs, in order to connect loam cake (2) and lower cover (3), fastening with flange circle (4), the outside, loam cake (2) central position has a joint of two joint connecting rods to link to each other with a joint of lever (6), constitute two joint connecting rods (5), can place below ground for making pump, lever is done Font, two ends are the pedal (7) of 30 ° of restriction corners, be attached thereto with axle, pedal is reserved screw in order to adding long lever, there is flow-in hole (8) at lower cover (3) center, influent stream valve (9) is settled on top, the bottom links to each other with influent stream pipe (10), the influent stream pipe is settled bleed valve (11), the influent stream pipe is connected with sealed well lid (13) with suction line (12) with well head, and the water lift degree of depth places well greater than the 9m valve (14) of will acting as a planted agent down, and the influent stream pipe combines with suction line disposes filter cleaner (15), the side of lower cover (3) has flow-out hole (16), pacify under it and stream valve (17), outflow tube (18) is connected with lower cover with flange, and outflow tube links to each other with conduit pipe (19) and water delivered to the place of needs, have lever dagger (20) to connect with axle with it between two lower covers, two lower covers are fixed on the support (21).

During to the lever application of force, as accompanying drawing, the right-hand member stacked tube stretches, and influent stream valve (9) is opened, and goes out to flow valve (17) and closes, and sucks medium; The compression of left end stacked tube, influent stream valve (9) cuts out, and goes out to flow valve (17) and opens, and discharges medium, and suction, current drainage body medium function are finished in reciprocating action.The medium that goes out stream from outflow tube (18) is a pressure flow, and the device shower nozzle is promptly realized spray.Open bleed valve (11) inflation that can sluice.

The elasticity stacked tube is the key element of this pump, if adopt natural neoprene synthetic rubber, its tearing strength 250-350kg/cm ², pull apart stretch rate 650-900%, 200% extends set deformation volume 8 12% after 24 hours surely, and maximum operation (service) temperature 120C °, brittleness temperature-50--70C °, ageing-resistant performance is good.Be the deformation of restriction stacked tube broadwise, but clamp or around steel wire makes its deformation intensity be not less than 2.5kg/cm ²

The heavy 7.5kg of model machine inhales journey and is not less than 9.0m, and lift depends on operator's the application of force and lever arm of force length, generally can reach 10m.Flow can calculate by following formula: Q=2V.f

Q-flow (L/S)

V-stacked tube volume-variation amount (L) f-reciprocating stroke frequency (inferior/S)

If sample stacked tube V=1.25L is f=0.5, then Q=4.5m ³/ h
