Description
Technical field:
The utility model relates to a kind of immersible pump more particularly to a kind of anti-dry immersible pumps.
Background technique:
In deep foundation pit construction because precipitation not in time due to cause foundation pit occur quicksand, piping, hole bottom unstability, crater wall collapse
Engineering accident can be found everywhere；Therefore, it to guarantee deep pit monitor, should just need to carry out using immersible pump before excavation of foundation pit uninterrupted
Precipitation, but there is problems in that due to manual inspection not in time, level switch damage the case where, lead to not accurately
It detects the water level in foundation pit, so that precipitation is excessive in foundation pit, causes the case where water level in foundation pit is lower than immersible pump water inlet
Occur；When the water level in foundation pit is lower than immersible pump water inlet, the discharge reduction of immersible pump position will form whirlpool and only draw
The phenomenon that taking air, do not absorb water, will cause immersible pump dry combustion method in this way seriously affects the service life of immersible pump.
Utility model content:
The purpose of this utility model is to provide a kind of structure is simple, immersible pump is avoided dry combustion method occur, and from improving diving
Pump the anti-dry immersible pump of service life.
The utility model is implemented by following technical solution: a kind of anti-dry immersible pump comprising immersible pump, water outlet main pipe,
Branch pipe and return pipe；Fixation is communicated with the water outlet main pipe on the water outlet of the immersible pump, in the side of the water outlet main pipe
It is fixed with the branch pipe on wall, the angle α of the branch pipe and the water outlet main pipe is 30 ° -45 °, one end of the branch pipe and institute
Water outlet main pipe connection is stated, the other end of the branch pipe is connected to return pipe fixation；One end of the return pipe and the branch
Pipe connection, the other end of the return pipe are located at below the water inlet of the immersible pump.
Further, the other end of the return pipe is greater than 10cm at a distance from the immersible pump bottom.
Further, the diameter of the branch pipe is 2-3cm.
Further, the return pipe is rubber tube.
The advantages of the utility model: 1, the utility model structure is simple, easily realizes, and easy for installation；When the water in foundation pit
When position is lower than immersible pump water inlet；Water in water outlet main pipe can flow in foundation pit because of gravity from branch pipe and return pipe again, be formed
Recurrent state avoids immersible pump from the phenomenon that dry combustion method occur, improves the service life of immersible pump, reduces maintenance replacement immersible pump
Cost；2, there is water in reflux in return pipe, rush mud, the silt etc. around immersible pump using the pressure of recirculation water
It opens, avoiding immersible pump and being placed in foundation pit for a long time causes to take out immersible pump difficulty or even can not take out because of mud siltation, guarantees
It is subsequent to be easy to take out immersible pump from foundation pit.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of the utility model embodiment.
Fig. 2 uses schematic diagram for the utility model.
Immersible pump 1, water outlet 1.1, water inlet 1.2, water outlet main pipe 2, branch pipe 3, return pipe 4, foundation pit 5.
Specific embodiment:
Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of anti-dry immersible pump comprising immersible pump 1, water outlet main pipe 2, branch pipe 3 and return pipe 4；?
Fixation is communicated with water outlet main pipe 2 on the water outlet 1.1 of immersible pump 1, and branch pipe 3, branch pipe 3 are fixed on the side wall of water outlet main pipe 2
Be 30 ° with the angle α of water outlet main pipe 2, in order to facilitate the water in water outlet main pipe 2 due to gravity out of branch pipe 3 to lower reflux, branch pipe
3 diameter is 2cm, and one end of branch pipe 3 is connected to water outlet main pipe 2, and the other end of branch pipe 3 is connected to the fixation of return pipe 4；Return pipe
4 one end is connected to branch pipe 3, and the other end of return pipe 4 is located at 1.2 lower section of water inlet of immersible pump 1；The other end of return pipe 4
With at a distance from 1 bottom of immersible pump be greater than 10cm, facilitate flushing mud when in order to flow back, avoid being blocked by mud when drawing water；Reflux
Pipe 4 is rubber tube.
Working principle: as shown in Fig. 2, immersible pump 1 is put into foundation pit 5, then one end binding and fixing of return pipe 4 are existed
On branch pipe 3, when the water level in foundation pit 5 be higher than immersible pump 1 water inlet 1.2 when, 1 normal use of immersible pump, at the same branch pipe 3 and return
Flow tube 4 is taken out the water in foundation pit 5 due to the effect of siphon outward, increases the pump drainage amount of immersible pump 1；Water level in foundation pit 5
Lower than immersible pump 1 water inlet 1.2 when, the water in the vertical section of water outlet main pipe 2 can be flowed downward from branch pipe 3 and be returned due to gravity
Flow tube 4 flows back into foundation pit 5, forms recurrent state, avoids immersible pump 1 from the phenomenon that dry combustion method occur, improve the use of immersible pump 1
Service life reduces the cost of maintenance replacement immersible pump 1；There is water in reflux in return pipe 4, it will using the pressure of recirculation water
Mud, silt around immersible pump 1 etc. are washed open, and avoiding immersible pump 1 and being placed in foundation pit 5 for a long time causes to take out because of mud siltation
Immersible pump 1 is difficult can not even to be taken out, and guarantee the subsequent easy taking-up immersible pump 1 from foundation pit 5；The utility model structure is simple,
It easily realizes, and easy for installation.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
