Description

Small head well air pressure picotan

The utility model relates to water lift equipment, especially a kind of small head well air pressure picotan.

At present, be applied to the water pump of small head well water lift, can divide two classes substantially; One class be motor and water pump at aboveground self-priming pump, this pump motor does not soak in water, the electrical fault rate is low, but because the suction journey of this pump in 8 meters, can only be applicable to very shallow well, can not use at deep-well.Another kind of is deep-well pump, and promptly diameter is in 10cm, and lift is more than 50 meters, deep-well pump is divided into two kinds again, and a kind of is screw pump, and another kind is a wing pump, screw pump is very fragile, and very trickle sand grains is arranged in the water, even in the water muddiness is arranged slightly, draw water and finish, water in the water pipe refluxes, and sand grains exists in the slit of screw rod and leather sheath, causes motor not start, if long-time energising, motor burns out easily.The way that solves is, water pump is put forward, and dismantles water outlet, cleans screw rod.Owing to water pipe, rope and cable are arranged on the water pump, these cables, rope weave in, transfer to put into pit shaft extremely require great effort, time-consuming, the bending degree that adds water inlet is little, tens meters water pipe is placed very inconvenient in garden.Its wing pump has made the Pyatyi impeller into by screw rod, requirement to water chaotic degree has reduced, but the rotation blade and the gap between the stator blade of impeller are little, after a period of time stops using, heavy mud in the water and corrosion thing will make two blade adhesions in relative rotation, make the whole rotation of Pyatyi impeller, can't normally go up water.In addition, the little bearing at its water outlet place ducks in drink, and it is normal lubricated to can not get oil, stops using after a period of time, and sand setting in the water and rotten rust can cause the stuck probability of bearing very high.

More than two kinds of water pumps, a common shortcoming is arranged, be exactly that motor is immersed in the water, because oil sealing, water seal can produce wearing and tearing under the high speed rotating of rotor, the injury region that adds rubber cushion, cable can seep water, and after using after a while, damages owing to intaking in the motor, cause shorten the maintenance rate height working life of water pump.

The purpose of this utility model provides a kind of hydroelectric separating, long service life, need not keep in repair, the lift height, to the small head well air pressure picotan of water chaotic degree no requirement (NR).

The purpose of this utility model is achieved through the following technical solutions, small head well air pressure picotan, comprise motor, air pump, sealing lid, sealing water pipe and outlet pipe, motor, air pump are placed in Jing Mianshang, air pump links to each other with seal by suction tude, the joint of seal and outlet pipe, water pipe is integrally welded, and outlet pipe is enclosed within the water pipe.Air pump and motor are mounted to one, coaxial rotation, and the air outlet of air pump is connected with suction tude on the seal by high pressure hose.Titting water outlet is longer than the water pipe joint, and the water pipe joint is coarser than titting water outlet, and the water pipe joint all encloses titting water outlet and suction tude in tube, and the water pipe joint is the frustoconic shape tube, and the end that thickness is big is welded on the seal.Outlet pipe is placed in the water pipe, is shorter in length than water pipe, and the bottom is an inclined point shape, and the flap valve of an energy recloser is arranged at the water pipe bottom.Outlet pipe connects a water valve to adapt to high and low diverse location water in aboveground part by three.

Advantage of the present utility model: the one, motor, air pump are placed on aboveground, realized that water, electricity separate, thereby improved greatly motor utilization efficiency, working life, minimizing frequency of maintenance, reduce cost of use; The 2nd, water outlet device of the present utility model is the water pipe of a go-no-go, and no impeller, no screw rod so water chaotic degree is not had specific (special) requirements, even sand grains or finger stone are arranged, also can be discharged smoothly; The 3rd, the device in the mine water is the halter of injection molding tube and band moving valve, does not have other whirligig and high frequency mechanical movement means, only needs valve seal reliably get final product, corrosion resistance by force, long service life, simple in structure, lift is high, easy to manufacture.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a main TV structure schematic representation of the present utility model;

Fig. 2 is the generalized section of the seal 9 among Fig. 1;

Fig. 3 is the elevational schematic view of the seal 9 among Fig. 1.

Among the figure: 1 motor, 2 air pumps, 3 barometers, 4 high pressure hoses, 5 suction tude, 6 titting water outlets, 7 water valves, 8 eminence ponds, 9 seals, 10 screws, 11 retaining injection molding tubes, 12 water outlet injection molding tubes, 13 halter self-acting valves, 14 boreholes wall, 15 waters surface, 16 assemble layer, 17 ground, 18 water pipe joints.

Small head well air pressure picotan, comprise motor 1, air pump 2, sealing lid 9, sealing water pipe and outlet pipe, motor 1, air pump 2 are placed in Jing Mianshang, air pump 2 links to each other with seal 9 by suction tude 5, seal 9 is integrally welded with the joint of outlet pipe, water pipe, and outlet pipe is enclosed within the water pipe.Air pump 2 and motor 1 are mounted to one, coaxial rotation, and the air outlet of air pump 2 is connected with suction tude 5 on the seal 9 by high pressure hose 4.Titting water outlet 6 is longer than water pipe joint 18, and water pipe joint 18 is coarser than titting water outlet, and water pipe joint 18 all encloses titting water outlet 6 and suction tude 5 in tube, and water pipe joint 18 is the frustoconic shape tube, and the end that thickness is big is welded on the seal 9.Outlet pipe is placed in the water pipe, is shorter in length than water pipe, and the bottom is an inclined point shape, and the flap valve of an energy recloser is arranged at the water pipe bottom.Outlet pipe connects a water valve to adapt to high and low diverse location water in aboveground part by three.

During use, connect a water valve 7, open water valve during water lift in the appropriate location of outlet pipe 6, can be in attached mistake of well head or lower position water outlet, close the water valve water supply such as pond 8 or water heater that then hoist; Seal 9 usefulness screws 10 are fixed on the well head, also can be placed on appropriate location in the pit shaft.When water lift not static, equate that with air pressure in the pit shaft water in the pit shaft enters in the sealing water pipe by halter valve 13 in the sealing water pipe 11, outlet pipe 12 is immersed in the water in the water pipe, and two manage with the interior water surface elevation of pit shaft and equate; Water pipe 11 bottom water valves 13 are in semi-closed state, when needing water lift, air pump 2 injects high-pressure air by suction tude 5 in the sealing water pipe, after the pressurization, valve closing makes water pipe become a seal container, internal air pressure is high more, water level in the outlet pipe rises high more, and when water level rises to the well head height when above, well water just is discharged from outside the well.The size of drain discharge is relevant with the air quantity and the pressure size of the diameter of outlet pipe, injection.Continue to inject high-pressure air, have lasting current to discharge in the outlet pipe, the water in the sealing water pipe is discharged to certain value, and promptly the underwater has dropped to the bottom of outlet pipe.At this moment there is air to enter in the outlet pipe, goes into ambient atmosphere in the time of after with the water emptying in the outlet pipe.This moment, the water pipe internal pressure descended greatly; because water level is higher than the interior water level of water pipe and has pressure difference in the well; the valve of water pipe bottom will be opened; water in the pit shaft enters in the water pipe; the size of inflow is relevant with the pressure decline size in the water pipe; should shut down a few minutes this moment or manually open the safety valve of air pump, so that water level equates that with the interior height of water level of pit shaft such water lift process is finished in the water pipe.When water lift once more, repeat said process, only be drawdown in the pit shaft, retaining reduces in the water pipe.

If stop water lift in the water lift process, the air pressure in the water pipe will keep a period of time, and water level descends gradually in the outlet pipe, and water can not enter in the water pipe in the pit shaft.Because the tightness factor, the water pipe internal air pressure descends gradually, and when dropping to less than inside and outside water level differential pressure, valve just is opened, and water just can enter in the water pipe in the pit shaft.
