Abstract
The utility model relates to self-priming pump, in particular to a self-priming pump for a deep well. The self-priming pump consists of a centrifugal pump and a jet device, wherein a backflow pipe and a water inlet pipe are arranged on the top of the jet device; the backflow pipe is communicated with a backflow opening of the centrifugal pump; the water inlet pipe is communicated with a water inlet of the centrifugal pump; the water inlet is communicated with a water outlet of the centrifugal pump; a bottom valve is arranged at the bottom of the jet device; a spray nozzle is formed in the jet device; the bottom of the spray nozzle is communicated with the backflow pipe; and a spray pipe is arranged on the top of the spray nozzle and is arranged in the water inlet pipe. By the self-priming pump, the self-priming capacity of more than 10 meters can be realized, so that the requirement of pumping water from the deep well of more than 10 meters is met.
Description
Technical field
The utility model is a kind of self-priming pump, particularly a kind of deep-well self-priming pump.
Background technique
The principle of drawing water of self-priming pump is: the water pump vane high speed rotating, and make pump intake form vacuum, the water in the pond leans on atmospheric pressure to go into hydraulic pressure in the water intake.Because of barometric pressure is about 10 meter water columns,, general self-priming pump is not more than 10 meters so inhaling journey.Consider the drag losses of water pipe, the self-priming pump on the market is inhaled journey and generally is no more than 8 meters, can not satisfy water lift in the deep-well more than 10 meters far away.
Summary of the invention
The purpose of the utility model is to inhale the not high defective of journey in order to overcome existing self-priming pump, invents a kind of deep-well self-priming pump.
The purpose of the utility model realizes as follows: said deep-well self-priming pump, to form by centrifugal pump and liquid jetting device, and the top of liquid jetting device is provided with reflow pipe and intake pipe; Reflow pipe is communicated with the refluxing opening of centrifugal pump, and intake pipe is communicated with the water intake of centrifugal pump, and water intake is communicated with the water outlet of centrifugal pump; The bottom of liquid jetting device is provided with bottom valve, is provided with nozzle in the liquid jetting device, and the bottom of nozzle is communicated with reflow pipe; The top of nozzle is provided with jet pipe, and jet pipe is located in the intake pipe.
The good effect of the utility model is following: the utility model can obtain the suction capacity greater than 10 meters, so satisfied the water lift demand of deep-well more than 10 meters.
Description of drawings
Fig. 1 is the utility model structural drawing.
Among the figure: 1, centrifugal pump; 2, liquid jetting device;
3, reflow pipe; 4, intake pipe;
5, refluxing opening; 6, water intake;
7, water outlet; 8, bottom valve;
9, nozzle; 10, jet pipe.
Embodiment
As shown in Figure 1
,Said deep-well self-priming pump is made up of centrifugal pump 1 and liquid jetting device 2, and the top of liquid jetting device 2 is provided with reflow pipe 3 and intake pipe 4; Reflow pipe 3 is communicated with the refluxing opening 5 of centrifugal pump 1, and intake pipe 4 is communicated with the water intake 6 of centrifugal pump 1, and water intake 6 is communicated with the water outlet 7 of centrifugal pump 1; The bottom of liquid jetting device 2 is provided with bottom valve 8, is provided with nozzle 9 in the liquid jetting device 2, and the bottom of nozzle 9 is communicated with reflow pipe 3; The top of nozzle 9 is provided with jet pipe 10, and jet pipe 10 is located in the intake pipe 4.
During work; The liquid that is produced higher-energy by centrifugal pump sprays from jet pipe with very high speed through reflow pipe; At this moment in liquid jetting device, form parital vacuum; The liquid exported is got in the liquid jetting device by bottom valve, and flows in the intake pipe with certain flow rate, then from the gateway of centrifugal pump with the water sucking-off.Because the utility model can obtain the suction capacity greater than 10 meters, so satisfied the water lift demand of deep-well more than 10 meters.
