Description
Technical field
The utility model relates to a kind of pump housing, particularly a kind of self-priming pump.
Background technique
Self-priming pump is that a kind of water that need in suction line, not be full of just can draw up next centrifugal pump to water automatically.It mainly includes body, be located at intake tunnel, exhalant canal on the body, be in the self-priming chamber and the pump housing between intake tunnel and the exhalant canal.In running, there is air in the water by the intake tunnel entering, after the air pressure of air enters in the self-priming chamber, can influence the centrifugal force of the pump housing, regular meeting occurs and can't water be delivered to the exhalant canal place when making the pump housing, causes the operation of self-priming pump stable inadequately.
Summary of the invention
To the deficiency that existing technology exists, the utility model provides a kind of self-priming pump stable, simple in structure.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of self-priming pump, and include body, be located at intake tunnel, exhalant canal on the body, be in the self-priming chamber and the pump housing between intake tunnel and the exhalant canal, described intake tunnel is located at the horizontal side of body; Exhalant canal is located at the horizontal top of body; Be provided with the pump housing with respect to the opposite side that intake tunnel one side is set on the body, the self-priming chamber is between the intake tunnel and the pump housing, and the pump housing is installed on the body through pump case; Pump case is provided with respectively the connecting passage with self-priming chamber and exhalant canal conducting; It is characterized in that: the bottom of said body is provided with the gas-liquid separation chamber that is communicated with self-priming chamber and exhalant canal through connecting passage on the pump case, and this gas-liquid separation chamber is provided with the opening with outside conducting, and this opening is provided with dismountable black box.
Adopt technique scheme, through bottom the gas-liquid separation chamber that is communicated with self-priming chamber and exhalant canal is set, when water is got into by inlet passage in body cross-section; Can the air in it be urged in the gas-liquid separation chamber; Air in the gas-liquid separation chamber then can be by the opening discharge that is provided with it on, after being provided with like this, makes pressure in the self-priming chamber can not receive the influence of air pressure; The centrifugal force of the pump housing is guaranteed, also makes whole operation more stable simultaneously.
The utility model further is set to: isolate through dividing plate between the self-priming chamber of body and the exhalant canal; Isolate through isolating plate between gas-liquid separation chamber and the self-priming chamber; Isolating plate and dividing plate are extended towards the installation place of the pump housing by a side of body respectively; One end of described pump case and body are fitted fixing, and the other end is arranged on isolating plate and the dividing plate.
Adopt technique scheme, compact structure is set like this, easy for installation; Reasonable use effective space.
The utility model further is set to: black box is for to be the sealing screw plug that screw thread spins with gas-liquid separation chamber place opening.
Adopt technique scheme, be provided with so simple in structure, convenient disassembly.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
A kind of self-priming pump as shown in Figure 1 includes body 1, is located at intake tunnel 2, exhalant canal 3 on the body 1, is in the self-priming chamber 4 and the pump housing 5 between intake tunnel 2 and the exhalant canal 3.Intake tunnel 2 is located at the horizontal side of body 1, and exhalant canal 3 is located at the horizontal top of body 1, is provided with the pump housing 5 with respect to the opposite side that intake tunnel 2 one sides are set on the body 1; Self-priming chamber 4 is between the intake tunnel 2 and the pump housing 5, and the pump housing 5 is installed on the body 1 through pump case 51, and pump case 51 is provided with respectively the connecting passage 52 with self-priming chamber 4 and exhalant canal 3 conductings; The bottom of body 1 is provided with the gas-liquid separation chamber 6 that is communicated with self-priming chamber 4 and exhalant canal 3 through connecting passage 52 on the pump case 51; This gas-liquid separation chamber 6 is provided with the opening 61 with outside conducting, and these opening 61 places are provided with dismountable black box 7, operator's dismounting and installation for ease; Sealing assembly 7 is preferably the sealing screw plug; Certainly, also can be sealing plug, also can play the effect of sealing; Just not seal screw plug convenient for its installation and dismounting, thus the utility model preferred the former.In the such scheme, the gas-liquid separation chamber 6 that is communicated with self-priming chamber 4 and exhalant canal 3 is set, when water is got into by inlet passage 2 through bottom at body 1 cross section; Can the air in it be urged in the gas-liquid separation chamber 6; Air in the gas-liquid separation chamber 6 then can be discharged by the opening that is provided with on it 61, after being provided with like this, makes self-priming chamber 4 interior pressure can not receive the influence of air pressure; The centrifugal force of the pump housing 5 is guaranteed, also makes whole operation more stable simultaneously.
In the utility model embodiment; In order effectively to utilize intrinsic space; Isolate through dividing plate 8 between the self-priming chamber 4 of body 1 and the exhalant canal 3, isolate through isolating plate 9 between gas-liquid separation chamber 6 and the self-priming chamber 4, isolating plate 9 and dividing plate 8 are extended towards the installation place of the pump housing 5 by a side of body 1 respectively; One end of pump case 51 and body 1 are fitted fixing, and the other end is arranged on isolating plate 9 and the dividing plate 8.The mode that is provided with like this can be omitted the multistep installation procedure in assembly process, improved the efficient of assembling.
