Abstract

The utility model discloses a kind of built-in type deep well submerged pump, the motor comprising water pump cover and be installed in water pump cover and single-suction multilevel vertical centrifugal pump, described single-suction multilevel vertical centrifugal pump is installed on the below in water pump cover, and motor is installed on the top in water pump cover; Leave gap between motor and water pump cover and form water flow passage, communicate with the water route of single-suction multilevel vertical centrifugal pump below water flow passage, above water flow passage, save conducting with the water outlet of submersible pump.The utility model, by arranging the exchange of pump and motor position, has carried out brand-new transformation to the cooling system of motor, can the heat dispersion of effective lifting motor, extends the working life of motor, reduces the cost of production of submersible pump, promote the portability of use.

Description

Built-in type deep well submerged pump
Technical field
The utility model relates to a kind of submersible pump, specifically a kind of built-in type deep well submerged pump.
Background technique
In the extended familys of pump, one motor and pump made by well submersible pump, immerses in underground water well and carry out a kind of pump aspirating and carry water, be widely used in farmland discharging-irrigating, industrial and mining enterprise, urban water supply and sewerage and sewage treatment etc.
Wherein have the unipump that a kind of well submersible pump is formed primarily of oil-filled type motor and single-suction multilevel vertical centrifugal pump, it has, and structure be simple, volume is little, lightweight, to install and easy to maintenance, security of operation, the feature such as reliable.And the common structure of this well submersible pump in existing market be pump upper motor under, on the basis of following international flange NEMA dimensional fits, stay bolt is used to carry out connection between the two, the water inlet position of pump is positioned at the top of motor, motor radiating is by motor casing surface transfer spreading from the inside to the outside, there is very large slowness in heat dissipation rate, motor housing must adopt the metal material of perfect heat-dissipating simultaneously, not only the high portability that simultaneously greatly have impact on submersible pump of cost.This external cause motor present position is positioned at the below of pump water inlet mouth, which dictates that the liquid around motor is actionless, and this will affect the final radiating effect of motor further.
Model utility content
For the problems referred to above, the utility model devises a kind of built-in type deep well submerged pump, it is by arranging the exchange of pump and motor position, brand-new transformation has been carried out to the cooling system of motor, can the heat dispersion of effective lifting motor, extend the working life of motor, reduce the cost of production of submersible pump, promote the portability used.For achieving the above object, the utility model is by the following technical solutions:
A kind of built-in type deep well submerged pump, the motor comprising water pump cover and be installed in water pump cover and single-suction multilevel vertical centrifugal pump, it is characterized in that: described single-suction multilevel vertical centrifugal pump is installed on the below in water pump cover, and motor is installed on the top in water pump cover; Leave gap between motor and water pump cover and form water flow passage, communicate with the water route of single-suction multilevel vertical centrifugal pump below water flow passage, above water flow passage, save conducting with the water outlet of submersible pump.
Further, twice mechanical seal device is provided with between above-mentioned motor and single-suction multilevel vertical centrifugal pump.
Further, above-mentioned motor and water outlet are provided with twice rubber seal between saving.
Further, above-mentioned water pump cover adopts plastic material.
The utility model adopts pump at lower motor in upper topology layout, and between motor and water pump cover, leave gap form the water flow passage that Submerged Motor Pumps internal watercourses must enter, once submersible pump is started working, the shell of motor just has continuous swiftly flowing current, the heat that motor produces can be taken away rapidly by the current of these flowings, electric machine temperature rise is effectively reduced rapidly, even if under severe Environmental Conditions, also can ensure the long time running of motor, the like product comparing conventional construction its working life can be extended greatly.
At this, because the heat radiation of motor is walked by the high speed flow water-band flowing through motor housing, make the heat dispersion of water pump cover also without extra demand, can need according to handy type and portability the plastic material adopting lightweight, not only cost is low, more greatly can alleviate the overall weight of submersible pump, submersible pump is made not merely to be applicable to the use of drawing water of deep-well, the irrigation of family's garden turf and flower beds can be widely used in equally, the washing of balcony and outdoor floor, the filling of little pond or water storage tank and emptying etc.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of built-in type deep well submerged pump, comprise water pump cover 1 and the motor 2 be installed in water pump cover 1 and single-suction multilevel vertical centrifugal pump 3, described single-suction multilevel vertical centrifugal pump 3 is installed on the below in water pump cover 1, and motor 2 is installed on the top in water pump cover 1; Leave gap 11 between motor 2 and water pump cover 1 and form water flow passage, communicate with the water route 31 of single-suction multilevel vertical centrifugal pump 3 below water flow passage 11, above water flow passage 11, save 4 conductings with the water outlet of submersible pump.
The utility model motor adopts built-in type structure, pump 3 and motor 2 integrated design, pump 3 at lower motor 2 upper, and between motor 2 and water pump cover 1, leave gap 11 form the water flow passage that Submerged Motor Pumps internal watercourses must enter, once submersible pump is started working, the shell of motor 2 just has continuous swiftly flowing current, the heat that motor 2 produces can be taken away rapidly by the current of these flowings, motor 2 temperature rise is effectively reduced rapidly, even if under severe Environmental Conditions, also the long time running of motor 2 can be ensured, the like product comparing conventional construction its working life can be extended greatly.
At this, for ensureing the water tightness of motor 2, be provided with twice mechanical seal device 5 between described motor 2 and single-suction multilevel vertical centrifugal pump 3, motor 2 and water outlet are provided with twice rubber seal 6 between saving 4.
In addition, because the heat radiation of motor 2 is walked by the high speed flow water-band flowing through motor housing, make submersible pump to the heat dispersion of water pump cover 1 without extra demand, the plastic material adopting lightweight can be needed according to handy type and portability, not only cost is low, more greatly can alleviate the overall weight of submersible pump, submersible pump is made not merely to be applicable to the use of drawing water of deep-well, the irrigation of family's garden turf and flower beds can be widely used in equally, the washing of balcony and outdoor floor, the filling of little pond or water storage tank and emptying etc.
The above, it is only the more excellent mode of execution of entirety of the present utility model, not do any pro forma restriction to model utility, every know-why according to this is modified any simple modification equivalent variations work that above case study on implementation does, and still belongs in the scope of technical solutions of the utility model.
