Abstract

The utility model relates to a full-automatic submersible pump, which is mainly composed of a water pump connected with a motor and a water tank connected with the top of the water pump, wherein a water outlet of the water pump is arranged in the central position of the top of a pump body, and a on-off valve arranged at the water outlet is arranged in the water tank arranged at the top of the water pump to make the configuration of the pump body thin farthest. The full-automatic submersible pump can be directly arranged in a deep well with a small diameter to use. A pressure switch arranged on a water outlet pipe can induct the change of the water pressure to automatically be switched on or off. Thereby, the pumping working of the water pump can be automatically controlled, certain water supply pressure is always kept in the water tank and the water supply purposes of automatic control and water pump at any time are realized. By using the utility model, a water storage tank in a high position and persons' special management are not required, the effects of saving electricity and water are obvious. The utility model is especially suitable for being installed and used in deep wells with a small diameter in red-bed hilly countries.

Description

Full-automatic submersible pump

Technical field:

The utility model relates to a kind of submersible pump, belongs to the deep-well pumping technical field of control automatically, specifically a kind of full-automatic submersible pump, and it is particularly suitable for small-bore, the interior use of degree of depth well that the red beds rolling country is made.

Background technique:

We know that China is one of country of water resources shortage in the world.At present, the situation that is becoming tight at the available surface water of China Cheng Ri, shortage of water resources has become a key factor of serious restriction China's industry and agricultural production development, particularly in the vast red beds rolling country of China, damage caused by a drought is quite serious, not only rural area plant short water supply, the regional people life potable water that has is all very difficult.For alleviate local agricultural production and people's domestic water serious problems, governments at all levels just take the measure of " well-digging, groundwater abstraction " on the spot, the resource that taps ground water resources is alleviated the damage caused by a drought that is becoming tight day.Because the soil property of red beds rolling country is hard and ground Zang Shui is darker, generally all be to adopt the manufacturing operation of digging a well of more piece drilling rod formula degree of depth well sinker, adopt the basic structural feature of the well that this mechanical means makes to be: the bore of well is minimum and the degree of depth is darker.For the special small-bore degree of depth well in this red beds rolling country, extract comparatively difficulty of well water, though supply to select for use at the submersible pump that has multiple model on the market, but mostly volume is bigger owing to the present submersible pump of producing, it can not directly be put into small-bore degree of depth well and use, it can only build draw water pumping plant and head-tank on ground, drinking-water pipe is stretched into the shaft bottom of small-bore degree of depth well, by the ground suction pump phreatic water is evacuated in the head-tank and stores for future use, certainly will increase capital cost like this, and the clean and maintenance management to head-tank also comparatively bothers in actual use, also cause the secondary pollution of water quality easily, though the less submersible pump of some volumes is also arranged on market, but the less submersible pump of volume does not mostly possess the function that automatic control is drawn water, need the special messenger to operate when drawing water, not only increased the daily operation management expense, and use also very inconvenience of operation.

The model utility content:

The utility model be propose on the basis of existing technology a kind of simple in structure, volume is tiny, can put into small-bore degree of depth well uses, and the full-automatic submersible pump of control automatically of realizing drawing water, it is achieved by the following technical solution: it mainly is made of the water pump that is connected in motor, it is characterized in that: water tank is installed on water pump, the keying valve that is fitted to the pump outlet place places in the water tank, be connected on the outlet pipe of water tank pressure switch is installed, with power firestreak cut-in pressure switch control machine operation, and the closed or disconnection of pressure switch is what to be controlled by the hydraulic pressure in the outlet pipe that is connected in water tank.Pressure switch can realize the purpose that automatically controlled water pump draws water according to variation in water pressure auto-closing or disconnection in the water tank, and can remain has certain pressure of supply water in the water tank.Structural feature of the present utility model is the top center position that the water outlet of water pump is arranged at the pump housing, the keying valve that is installed on water outlet places in the water tank at water pump top, can make tinyization of pump housing profile, be particularly suitable in small-bore, the degree of depth well that the red beds rolling country is made, installing and using.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

Embodiment:

The full-automatic submersible pump that the utility model proposes is implemented by following technological scheme: it is to be connected in the water pump 6 of motor 2 and to be made of the water tank 8 that bolt 18 is connected in water pump 6 tops by bolt 16, do the water feed apparatus that constitutes by grid frame 17 and filter screen 3 in the bottom of water pump 6, water outlet 7 tops that are arranged at water pump 6 top center positions are equipped with vavle shelf 15, the keying valve 9 that is fitted to water outlet 7 places in the water tank 8, two hoisting rings 14 are installed on the water tank 8, can be convenient to submersible pump is put into small diameter deep well 1, the outlet pipe 10 that is connected in water tank 8 tops passes well lid plate 12 and is connected in the water supply piping, pressure switch 11 is installed, and the closed or disconnection of pressure switch 11 is to be controlled by the hydraulic pressure pressure in the outlet pipe 10 that is connected in water tank 8 on the tee union that is serially connected with outlet pipe 10.It is work like this: during use, submersible pump is put into the bottom hole location of small diameter deep well 1, power lead 13 passes well lid plate 12 cut-in pressure switches 11 control motors 2, well water is through filter screen 3, water inlet 4 enters in the water pump 6, the impeller 5 that drives water pump 6 when motor 2 energisings rotates, the phreatic water that extracts constantly passes through the filter screen 3 of water pump 6 bottoms, water inlet 4 sucks in the water pump 6, and the keying valve 9 that backs down water pump 6 top water outlets 7 places enters in the water tank 8, when the hydraulic pressure in the water tank 8 increases to setting value gradually, under the effect of hydraulic pressure pressure, pressure switch 11 is disconnected, motor 2 outages stop pumping, water outlet 7 with water pump 6 under the hydraulic action of keying valve 9 in water tank 8 seals, at this moment in water tank 8 and outlet pipe 10 pipings, form certain pressure of supply water, when user's water, hydraulic pressure descends thereupon, and pressure switch 11 releases of pressure are closed again, motor 2 is switched on once more drive impeller 5 rotations of water pump 6 to be drawn water, can supply with well water continuously to the user.When the user stopped water, the hydraulic pressure in the water tank 8 increased to setting value again gradually, and pressure switch 11 is disconnected once more, motor 2 work that stops pumping of cutting off the power supply.So circulation can make in water tank 8 and outlet pipe 10 pipings and remain certain pressure of supply water repeatedly, realizes controlling automatically the purpose of drawing water, provide at any time for the user phreatic water of sanitation and hygiene.
