Abstract
The utility model discloses a packingless self-suction pump, which comprises a motor, a pump body, a pump stand, a liquid outlet tube (1) and a liquid inlet tube (2). Wherein, the liquid inlet tube (2) is provided with a liquid inlet tube filter screen (3) at one end; a self circulation flusher is positioned between the liquid outlet tube (1) and the liquid inlet tube filter screen (3). The self circulation flusher is composed as following: the liquid inlet tube filter screen (3) is provided with a flooding ejector priming (4) on its periphery; between the liquid outlet tube (1) and the flooding ejector priming (4) is a water-circulating pipe (5) which is positioned with a checkvalve (6). Structured as above, the pump unit can disperse the grain and stir the precipitate during sewage discharging, thus making a more through discharge and improving the discharging capacity and the efficiency.
Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of self-priming pump that is used for fed sheet of a media.
Background technique
At present, being applied in industries such as petrochemical industry, smelting, papermaking, medicine, food processing often adopts self-priming pump to carry out blowdown work, but existing self-priming pump pump group is when carrying out the blowdown operating mode, often because of the shoal materials precipitation, particle concentrates on certain, and the feed liquor filter screen part that makes is stopped up, thereby has influenced the proper functioning of pump group, makes blowdown thoroughly clean inadequately.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of when pump group execution blowdown operating mode, can play discrete particles, the non-sealing self-sucking pump of stirring precipitation shoal materials.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises motor, the pump housing, pump seat, drain pipe, liquid inlet pipe, liquid inlet pipe one end is equipped with the feed liquor filter screen, and a self-circulating water Rinsing unit is installed between drain pipe and the feed liquor filter screen.The self-circulating water Rinsing unit is to form like this: in feed liquor filter screen periphery the flushing sparger is installed, is connected with a circulating water pipeline between drain pipe and the flushing sparger, an one-way valve is installed on the circulating water pipeline.On described flushing sparger, open some apertures, so that medium injection and going out.
The said structure that the utility model adopts makes the pump group when carrying out the blowdown operating mode, can play discrete particles, stirs the effect of precipitation shoal materials, thereby makes blowdown more clean thoroughly, has improved pollution discharge capability and contaminant removal effectiveness.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that the structural representation of non-sealing self-sucking pump
Embodiment
As shown in Figure 1, this kind non-sealing self-sucking pump comprises motor, the pump housing, pump seat, drain pipe 1, liquid inlet pipe 2, and liquid inlet pipe 2 one ends are equipped with feed liquor filter screen 3, and a self-circulating water Rinsing unit is installed between drain pipe 1 and the feed liquor filter screen 3.The self-circulating water Rinsing unit is to form like this: in feed liquor filter screen 3 peripheries flushing sparger 4 is installed, is connected with a circulating water pipeline 5 between drain pipe 1 and the flushing sparger 4, an one-way valve 6 is installed on the circulating water pipeline 5.Open some apertures on the described flushing sparger 4, so that medium injection and going out.When self-priming pump when carrying out blowdown work running, liquid medium enters the pump housing by feed liquor filter screen 3, liquid inlet pipe 2, arrive drain pipe 1, the medium that has pressure enters circulating water pipeline 5 from drain pipe 1, enter the flushing sparger 4 that is looped around feed liquor filter screen 3 peripheries from circulating water pipeline 5, under pressure, liquid medium aperture from it is spouting, thereby form the injection curtain at feed liquor filter screen 3 peripheries, reach flushing, dispersion, stir the effect that precipitates shoal materials.
Claims (3)
1, a kind of non-sealing self-sucking pump comprises motor, the pump housing, pump seat, drain pipe, liquid inlet pipe, and liquid inlet pipe one end is equipped with the feed liquor filter screen, it is characterized in that: a self-circulating water Rinsing unit is installed between drain pipe and the feed liquor filter screen.
2, a kind of non-sealing self-sucking pump according to claim 1, it is characterized in that described self-circulating water Rinsing unit is to form like this: the flushing sparger is installed in feed liquor filter screen periphery, be connected with a circulating water pipeline between drain pipe and the flushing sparger, an one-way valve is installed on the circulating water pipeline.
3, a kind of non-sealing self-sucking pump according to claim 2 is characterized in that opening some apertures on the described flushing sparger, so that medium injection and going out.
