Description
Technical field
The utility model relates to a kind of self-priming pump.
Background technique
Common centrifugal pump is when normal mounting, and its precondition is by impeller submergence in a liquid, so, in the suction line end of pump, bottom valve must be installed; Prestart first should be filled with liquid or be adopted vacuum pump in the pump housing, and drained by the gas in pipeline and make liquid-immersed impeller, and make to be full of liquid in pipeline, pump can normally work.
Although both economical toward the mode of pump housing inner canister liquid, before each use, need workman manually filling, cumbersome.And use vacuum pump cost relatively higher.
Model utility content
For the technical problem of above-mentioned existence, the utility model provides vertical self-sucking pump, automatically keeps self-priming pump starting condition after each use, for next time uses ready.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of vertical self-sucking pump, and comprise the pump housing and be arranged on the pump shaft in the pump housing, described pump shaft is by driven by motor; Described pump shaft front end is provided with impeller, pump shaft is positioned at impeller rear and is provided with sub-propeller; It is characterized in that: the described pump housing is divided into liquid storage room and air-water separation chamber by impeller and sub-propeller; Being liquid storage room below described impeller, is air-water separation chamber between described impeller and sub-propeller; Described liquid storage room is provided with suction elbow, described air-water separation chamber is provided with the bend pipe that spues; Suction elbow has ventilating hole, described ventilating hole is provided with the control valve be connected with motor, when making electric motor starting ventilating hole close and motor cuts out time ventilating hole open; The described bend pipe that spues is provided with safety check.
Improve as one, described suction elbow and the bend pipe that spues are the bend pipe upwarped; Described ventilating hole is arranged on the upper end of suction elbow, is vented when being conducive to pouring water for the first time.
Improve as one: the diameter of described sub-propeller is greater than impeller.The reverse net lift that sub-propeller produces is greater than the net lift of main impeller, guarantees the validity of sub-impeller seal.
Usefulness of the present utility model is: the self-priming pump with said structure, after finishing using, automatically keeps its starting condition at every turn, all pours water without the need to using at every turn.Also without the need to installing extra equipment for self-priming pump.It is easy to use, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 motor, 2 pump shafts, 3 impellers, 4 sub-propellers, 5 liquid storage rooms, 6 air-water separation chambers, 7 suction elbows, 8 spue bend pipe, 9 liquid filling holes, 10 ventilating holes, 11 control valves, 12 safety check.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises the pump housing and is arranged on the pump shaft 2 in the pump housing, and described pump shaft 2 is driven by motor 1; Described pump shaft 2 front end is provided with impeller 3, pump shaft 2 is positioned at impeller 3 rear and is provided with sub-propeller 4; The diameter of sub-propeller 4 is greater than impeller 3.The described pump housing is divided into liquid storage room 5 and air-water separation chamber 6 by impeller 3 and sub-propeller 4; Be liquid storage room 5 below described impeller 3, described impeller 3 and accessory lobes 4 are air-water separation chamber 6 between taking turns; Described liquid storage room 5 is provided with suction elbow 7, described air-water separation chamber 6 is provided with the bend pipe 8 that spues; Suction elbow 7 has ventilating hole 10, described ventilating hole 10 is provided with the control valve 11 be connected with motor 1, when motor 1 is started ventilating hole 10 close and motor 1 cuts out time ventilating hole open 10; The described bend pipe 8 that spues is provided with safety check 12.Described suction elbow 7 and the bend pipe 8 that spues are the bend pipe upwarped; Described ventilating hole 10 is arranged on the upper end of suction elbow 7.
Prestart first should fill with liquid (suction elbow 7 is provided with liquid filling hole 9) in the pump housing for the first time, fill rear closedown liquid filling hole 9, starting electrical machinery 1, control valve 11 is closed condition simultaneously, air-water separation completes in air-water separation chamber 6, form self-priming performance, when the gas in suction elbow 7 drains, pump starts normal work; When motor 1 stops, control valve 11 is opened simultaneously, and suction elbow 7 is communicated with air, and the liquid in pipeline all exhausts by the effect avoided because of siphon, and meanwhile, safety check 12 is closed condition; And high liquid level (HLL) when ensureing the liquid place starting of accumulating in the pump housing, for next time starts ready.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
