Abstract
The utility model discloses a pump body of a self-suction sewage pump. The pump body is internally provided with a volute chamber, a liquid storage chamber, a gas-liquid separation chamber and a reflowing hole, wherein an air exhausting opening is arranged on the pump body corresponding to the upper end of the gas-liquid separation chamber; and an inlet of the reflowing hole is located at the bottom of the volute chamber. The pump body of the self-suction sewage pump has the advantages of good self-suction performance, short self-suction time and strong passing capability.
Description
Technical field
The utility model designs a kind of self-suction sewage pump, is meant a kind of pump housing of self-suction sewage pump especially.
Background technique
Self-suction sewage pump of the prior art has a certain amount of water in pump, pump starts the turning effort of back owing to impeller, the empty G&W in the suction line, and, be discharged to gas-liquid separation chamber with its sufficient mixing.The gas on gas-liquid separation chamber top is overflowed, and the water of bottom returns impeller through the return port on the pump housing, and the residual gas with suction line mixes again; Up to all draining the gas in pump and the inlet pipeline; Make to form certain degree of vacuum in the pump, accomplish self-priming, and normally draw water.But the return port aperture size in this pump structure is little and design is not too reasonable, has the long defective of easy blocking and self-priming time.
Summary of the invention
The purpose of the utility model is the shortcoming for the self-priming time length that overcomes the existing technology existence, and the pump housing of a kind of pump housing a kind of self-suction sewage pump reasonable in design is provided.
For realizing above-mentioned purpose, the technological scheme of the utility model is to be provided with volute chamber, liquid storage room, gas-liquid separation chamber and return port in this pump housing, and the upper end of the relative gas-liquid separation chamber of the pump housing is provided with relief opening, and the inlet of said return port is positioned at the volute chamber bottom position.Through this setting, the inlet of return port is positioned at the volute chamber bottom, liquid full out flow in the volute chamber in the return port that can be, and it is good to have a gas-liquid separation effect, the advantage that self-priming time is short.
The diameter that further setting is said return port is for being not less than 100mm.Through this setting, the return port passing capacity is strong, can pass through particle maximum diameter 75mm, preferably resolves blockage problem, is convenient to discharge large particle suspended matter liquid medium.
Further be provided be return port be shaped as the spirality circular hole.
The beneficial effect of the utility model is:
The utility model self-priming performance is good, and the area of return port is big, and the liquid that flows to volute chamber through return port is many, and gas-liquid separation effect is good, and self-priming time is short; Passing capacity is strong, can pass through particle maximum diameter 75mm, preferably resolves blockage problem, is convenient to discharge large particle suspended matter liquid medium.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model structural representation;
The A-A sectional view of Fig. 2 Fig. 1.
Embodiment
Through embodiment the utility model is carried out concrete description below; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned model utility.
The embodiment of the utility model shown in Fig. 1-2; Be provided with volute chamber 3, liquid storage room 5, gas-liquid separation chamber 2 and return port 4 in this pump housing 1, this return port of present embodiment be shaped as the spirality circular hole, the upper end of the pump housing 1 relative gas-liquid separation chamber 2 is provided with relief opening 6; Gas is overflowed from relief opening 6; Import 41 places of said return port 4 are positioned at volute chamber 3 bottom positions, so, and can be so that liquid full out flow in the volute chamber 3 in the return port 4; It is good to have gas-liquid separation effect, the advantage that self-priming time is short.
In addition, for deslagging and the anti-plugging ability that improves the utility model, the diameter of said return port 4 is for being not less than 100mm, preferably the diameter 100mm of this return port 4 of present embodiment.
