Abstract
The utility model relates to a self-suction type water pump, which is composed of a motor, a pump body, an air-water separation chamber, an impeller, a water inlet and a water outlet, wherein, a check valve is arranged on the water inlet, and the water outlet is arranged on the air-water separation chamber; a center of the impeller is matched with a motor shaft in the circumferential direction via splines or pin keys, the center of the impeller is movably matched with the motor shaft in the axial direction, and an air hole and a water outlet hole which are communicated with the air-water separation chamber are arranged in the pump body and beside a cut water. The utility model has the advantages of simple and reasonable structure, convenient maintenance and usage and good hydraulic performance.
Description
The utility model relates to a kind of self-priming water pump, belongs to a kind of wing pump.
Self-priming water pump of the prior art is of a great variety, and the impeller and the transmission shaft of existing self-priming water pump are fastenedly connected, and maintenance is inconvenient on the one hand, and on the other hand for wing pump, impeller does not have self-adjusting possibility in the pump housing, influence hydraulic performance, causes damage easily yet.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple and reasonable for structure, maintenance, easy to use, the good self-priming water pump of hydraulic performance.
Self-priming water pump of the present utility model, form by motor, the pump housing, air-water separation chamber, impeller, water intake, water outlet, an one-way valve is housed on the water intake, water outlet is positioned on the air-water separation chamber, it is characterized in that: match with motor reel by spline or pin key at circumferencial direction in the impeller center, the impeller center is axially cooperating with motor reel is movable, and there is pore and the osculum that is connected with air-water separation chamber on the cut water side in the pump housing.
Self-priming water pump of the present utility model, simple and reasonable for structure, maintenance, easy to use, hydraulic performance is good.
For introducing self-priming water pump of the present utility model in detail, be elaborated below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of facing of self-priming water pump of the present utility model;
Fig. 2 is the A-A sectional structure chart among Fig. 1;
Fig. 3 is the B-B sectional structure chart among Fig. 2.
Referring to Fig. 1-3, self-priming water pump of the present utility model, by motor 1, the pump housing 2, air-water separation chamber 3, impeller 4, water intake 5, water outlet 6 is formed, an one-way valve 7 is housed on the water intake 5, water outlet 6 is positioned on the air-water separation chamber 3, it is characterized in that: match with the axle of motor 1 by spline or pin key 8 at circumferencial direction in impeller 4 centers, impeller 4 centers are axially cooperating with the axle of motor 1 is movable, impeller 4 axially can have certain free gap in the pump housing 2, and very easily dismantle during maintenance, avoid to change after the corrosion problem of impeller, there is pore 10 and the osculum 11 that is connected with air-water separation chamber 3 on cut water 9 sides in the pump housing 2, make water pump in finishing the process of self-priming, a small amount of diversion that the pump housing and air-water separation are indoor, form good outer circulation by pore and osculum, to discharge in the air from pump body, thereby guarantee its self-priming performance, on air-water separation chamber 3, have water inlet 12, when just using, can in air-water separation chamber 3, add water by water inlet.
Be to prolong the working life of the impeller 4 and the pump housing, also for the pump housing that adopts plastics creates conditions, meet the rationality of structure simultaneously, be inlaid with copper sheet 13 on the axial circumferential surface that contacts having with impeller on the pump housing 2, the above-described pump housing 2 comprises pump cover 2 '.
The pump impeller of self-priming water pump of the present utility model adopts impeller, and its waterpower runner 14 is produced on the pump housing 2, and relatively simple for structure, not only cost is low, and simplified manufacturing process, is suitable for producing in enormous quantities.
Claims (3)
1, a kind of self-priming water pump, form by motor, the pump housing, air-water separation chamber, impeller, water intake, water outlet, an one-way valve is housed on the water intake, water outlet is positioned on the air-water separation chamber, it is characterized in that: match with motor reel by spline or pin key at circumferencial direction in the impeller center, the impeller center is axially cooperating with motor reel is movable, and there is pore and the osculum that is connected with air-water separation chamber on the cut water side in the pump housing.
2, self-priming water pump according to claim 1 is characterized in that having water inlet on the above-mentioned air-water separation chamber.
