Abstract
The utility model relates to a cooling housing comprising a housing body, an inlet pipe, an air hole and a water-saving valve. The cooling housing is characterized in that the air hole is arranged above the housing body below which the inlet pipe is disposed; the water-saving valve is arranged in the middle of the inlet pipe; a water pipe mouth is disposed on a water outlet of a submersible pump; the inner diameter of a water inlet end of the water-saving valve is far larger than that of a water outlet end of the water-saving valve. Due to the fact that the inner diameter of the water inlet end of the water-saving valve is far larger than the inner diameter of the water outlet end of the water-saving valve, when water flows into the inlet pipe from a water outlet of the submersible pump, water flows slowly after passing the water-saving valve. Furthermore, with the air hole arranged above the housing body of the cooling housing, when water flows into the housing body of the cooling housing, air in the cooling housing can be discharged from the air hole; when water in the housing body of the cooling housing is full, excess water can be discharged from the air hole. The cooling housing is simple in structure, easy to use, safe and reliable.
Description
Technical field
The utility model relates to drainage machinery field, specifically a kind of cooling outer cover.
Background technique
Submersible pump refers to the pump of working environment below the water surface, it must be full of liquid in suction pipe and pump, after turn on pump before turn on pump, impeller High Rotation Speed, liquid wherein, along with blade rotates together, under the effect of centrifugal force, flies away from impeller and outwards penetrates, the liquid speed in pump case explosion chamber penetrating is slack-off gradually, pressure increases gradually, and then from pump discharge, discharge tube flows out.Now, in blade center, because being thrown toward, liquid around forms the vacuum low-pressure district that not only there is no air but also there is no liquid, liquid in liquid pool is under the atmospheric effect of pond face, in suction pipe inflow pump, liquid is exactly so continuously from liquid pool, be pumped up and continuously from discharge tube, flow out.
Submersible pump unit is by: water pump, submersible motor (comprising cable), conduit pipe and control switch four is most of forms.Submersible pump is single-suction multilevel vertical centrifugal pump; Submersible motor is airtight water-filling wet type, vertical three-phase squirrel-cage induction motor, and motor is connected by pawl formula or singly-bound cartridge type coupling with water pump; The three core cable of different size is equipped with; Starting equipment is air-break switch and the self-coupling decompression air-operated apparatus of different capacitance grade, and the steel pipe that conduit pipe is different-diameter is made, and adopts flange to connect, and high-lift electric pump adopts gate valve to control.
Because submersible pump working environment is below the water surface, but in some particular surroundings, do not get rid of the possibility that water pump emerges, at this time due to the reason of the outer machinery of environment own, pump body temperature may significantly raise, now just need to use cooling system, also there is no a kind of self-flow type water cooling outer cover simple in structure of submersible pump special use at present.
Model utility content
The utility model, just for above technical problem, provides a kind of self-flow type water cooling outer cover simple in structure of submersible pump special use.
The utility model is achieved through the following technical solutions.
A cooling outer cover, comprises cover body, intake pipe, air hole, water-saving valve, it is characterized in that air hole is arranged on cover body top, and intake pipe is arranged on cover body bottom, and water-saving valve is arranged on intake pipe middle part, and the intake pipe mouth of pipe is arranged on submersible pump water outlet.Water-saving valve water intake end internal diameter is much larger than waterexit end internal diameter.
Because water-saving valve water intake end internal diameter described in the utility model is much larger than waterexit end internal diameter, when current flow into intake pipe from submersible pump water outlet, current by water-saving valve can slow down, and cooling outer cover cover body top is provided with air hole, in cooling water cover cover body, there are current fashionable, gas in cooling water cover can be discharged from air hole, and when in cooling water cover cover body, water is full, unnecessary water also can be discharged from air hole.
This cooling cover structure is simple, easy to use, safe and reliable.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural profile schematic diagram, wherein:
1-cover body, 2-intake pipe, 3-air hole, 4-water-saving valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of cooling outer cover, comprise cover body 1, intake pipe 2, air hole 3, water-saving valve 4, it is characterized in that air hole 3 is arranged on cover body 1 top, intake pipe 2 is arranged on cover body 1 bottom, water-saving valve 4 is arranged on intake pipe 2 middle parts, and intake pipe 2 mouths of pipe are arranged on submersible pump water outlet.Water-saving valve 4 water intake end internal diameters are much larger than waterexit end internal diameter.
Because water-saving valve 4 water intake end internal diameters described in the utility model are much larger than waterexit end internal diameter, when current flow into intake pipe 2 from submersible pump water outlet, current by water-saving valve 4 can slow down, and cooling outer cover cover body 1 top is provided with air hole 3, in cooling water cover cover body 1, there are current fashionable, gas in cooling water cover can be discharged from air hole 3, and when cooling water cover cover body 1 interior water is full, unnecessary water also can be discharged from air hole 3.
This cooling cover structure is simple, easy to use, safe and reliable.
Claims (2)
1. a cooling outer cover, comprises cover body, intake pipe, air hole, water-saving valve, it is characterized in that air hole is arranged on cover body top, and intake pipe is arranged on cover body bottom, and water-saving valve is arranged on intake pipe middle part, and the intake pipe mouth of pipe is arranged on submersible pump water outlet.
2. a kind of cooling outer cover according to claim 1, is characterized in that described water-saving valve water intake end internal diameter is much larger than waterexit end internal diameter.
