Body part and by the guide part of liquid outlet described in the current deflecting in the impeller, the impeller has what is be located therein to enter
Mouth and ring set the outlet with its edge part, and the entrance is connected with the front cavity, and the outlet is connected with the rear chamber
Logical, the guide part includes fixed ring and multiple deflectors being arranged in the fixed ring, and the deflector is from the fixation
The Inside To Outside inclination of ring extends arranges in vortex shape.
Preferably, it is provided with the locating piece of protrusion on the deflector, is covered after described and is provided with locating slot, the positioning
Block is embedded in the locating slot.
It is further preferred that the impeller is arranged between the separating device and the rear cover, the impeller includes circle
The middle part of plate-like have the impeller upper cover of circular open, discoid impeller bottom and it is multiple from setting the upper cover with it is described
The rear cover setting is close in radial water stream channel between bottom, the impeller bottom, and the rear cover is adjacent with the impeller
Surface indentation is provided with multiple radiating grooves, and the radiating groove extends from the middle part of the rear cover to edge part.
It is further preferred that the end of the radiating groove and the locating slot are interconnected.
Preferably, the separating device is eccentrically set on the lower part of the cavity.
Preferably, the guide part is located at the middle part of the separating device.
It is further preferred that the middle part of the guide part has through-hole, water strainer, the drainage are provided on the through-hole
Net is in circular cone shape, and one end is fixedly connected with the guide part, and the other end and the front cover are inconsistent.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
Since water flow is imported impeller by separating device by the utility model, so that the minimum amount of water of starting self priming pump
It reduces, while the deflector on separating device can quickly export water flow, water speed is lifted out, to promote self priming pump
Working efficiency.

Specific embodiment
Embodiment shown in reference to the accompanying drawing is further described the utility model:
Referring to shown in attached drawing 1-2, a kind of self priming pump comprising front cover 1, rear cover 2 with inlet 11 and liquid outlet 12,
Impeller 3 in the pump housing composed by front cover 1 and rear cover 2 is set, the separating device 4 in the pump housing, and driving impeller 3 are set
Motor 7；Front cover 1 and rear cover 2 are harmonious with forming columned cavity 5, and separating device 4 includes that cavity 5 is separated into front cavity 51
With the body part 41 of rear chamber 52 and by the guide part 42 of the current deflecting liquid outlet 12 in impeller 3, impeller 3, which has, to be located therein
The entrance and ring in portion set the outlet with its edge part, and entrance is connected with front cavity 51 by guide part 42, outlet and rear chamber
52 are connected, guide part 42 include fixed ring 42a and multiple deflector 42b being arranged on fixed ring 42a, deflector 42b from
The Inside To Outside inclination of fixed ring 42a extends arranges in vortex shape.
Since water flow is imported impeller 3 by separating device 4, so that the minimum amount of water of starting self priming pump is reduced, while
Deflector 42b on separating device 4 can quickly export water flow, be lifted out water speed, to promote the work effect of self priming pump
Rate.
Specifically, referring to raised locating piece 42c shown in attached drawing 3, is provided on deflector 42b, it is fixed to be provided on rear cover 2
