Abstract

The utility model discloses a self-priming anti-corrosive water pump comprising a shell, a base, an impeller, a water priming chamber, a water inlet, a water outlet and the like. The water pump is characterized in that the shell, the base, the impeller, the water inlet and the water outlet are all made of polyester resin fiberglass reinforced plastics by using a molding pressing process; the impeller comprises a turntable and four vanes evenly distributed on one side of the turntable; and the root of each vane is curved in the shape of a circular arc and has a certain distance from a central hole of the turntable. Because components of the water pump are made of the polyester resin fiberglass reinforced plastics by using the molding pressing process, the self-priming anti-corrosive water pump has the advantages of abrasion resistant performance, aging resistant performance, impact resistant performance, structure strength increase, weight alleviation, volume reduction and attractive appearance.

Description

Self-priming corrosion-resistant water pump

Technical field

The utility model relates to a kind of self prime pump, particularly a kind of corrosion-resistant high-lift self prime pump.

Prior art

The corrosion-resistant water pump of existing self prime pump all is to adopt politef and various resin material to make.Because the narrow limitation of politef and resin material itself though the traditional self-priming corrosion-resistant water pump that makes has reached corrosion resistant purpose, also exists abrasion resistance properties poor, structural strength is low, impact resistance defective poor, that easily wear out.After being that power connects, vibrations occurring and be easy to rupture.In addition common self-priming corrosion-resistant water pump is because the strength problem of the housing of considering makes that the volume of water pump own is excessive, and cost increases, and lift is little, also hinders attractive in appearance.

Summary of the invention

In view of designing and manufacturing, above situation main task of the present utility model a kind ofly can overcome aforementioned corrosion-resistant self-priming water pump defective, withstand corrosion, and wear-resistant, the resistance ability is strong, ageing-resistant, big lift, and volume is little less, weight is lighter relatively, the self-priming corrosion-resistant water pump of beautiful shape.

The purpose that the utility model proposes is achieved in that a kind of self-priming corrosion-resistant water pump, comprise shell, pedestal, impeller, suction chamber, water intake, water outlet, band seal ring from suction cover, the water sucking mouth of suction chamber is communicated with the water-inlet cavity of shell and water intake thereof, impeller is arranged in suction chamber, pedestal is with after shell is connected, space between suction chamber and the impeller forms pressurizing chamber, and described pressurizing chamber has passage to be communicated with water chamber and water outlet thereof in the shell; The center hole of impeller by passing pedestal with the fixing core wheel of center hole be located at pedestal power outward and be connected; It is characterized in that: described shell, pedestal, suction chamber, impeller are by the compression molding of polyester resin glass fiber reinforced plastic; Impeller is by wheel disc and constituting at four uniform blades of wheel disc one side, and the root of blade is the circular arc bending, and at a distance of the center hole certain distance of wheel disc.

It is conspicuous that the self-priming corrosion-resistant water pump of the utility model is compared its advantage with existing polyvinyl plastics with the rubber anti-corrosive pump: because pump part is made through die press technology for forming with polyester resin glass fiber reinforced plastic, make the self-priming corrosion-resistant water pump of the utility model have that wear resistance, ageing-resistant, impact resistance and framework intensity increase, weight saving, volume reduces, beautiful shape.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to the self-priming corrosion-resistant water pump among the figure, comprise shell 1, pedestal 2, impeller 4, suction chamber 8, water intake 6, water outlet 3, be with seal ring 7 from suction cover, the water sucking mouth of suction chamber 8 is communicated with the water-inlet cavity of shell and water intake 6 thereof, impeller is arranged in suction chamber, pedestal is with after shell is connected, space between suction chamber and the impeller forms pressurizing chamber, and described pressurizing chamber has osculum 10 to be communicated with water chamber and water outlet 3 thereof in the shell; The center hole of impeller by passing pedestal with the fixing core wheel of center hole be located at pedestal power outward and be connected; It is characterized in that: described shell 1, pedestal 2, suction chamber 8, impeller 4 are by the compression molding of polyester resin glass fiber reinforced plastic; Impeller 4 is by wheel disc and constituting at four uniform blades of wheel disc one side, and the root of blade is the circular arc bending, and at a distance of the center hole certain distance of wheel disc.

Above-mentioned blade top thickness is 4mm, and thickens downwards gradually to 6mm; Above-mentioned pedestal 2 appearance integral body are processed with by the stiffening rib 5 of center hole to radial distribution all around; Above-mentioned shell 1 inwall has 12 semi-circular stiffening ribs 13; Respectively there is at least one wedge shape stiffening rib 12 on four jiaos of mounting hole both sides of outer surface of outer cover; Above-mentioned suction chamber water outlet place is provided with a barrier plate 9; Above-mentioned water intake 6 bores are greater than water outlet 3 bores; Be provided with in the above-mentioned water-inlet cavity one the band rubber seal from suction cover 7, self-priming caping end has a waist type raised line 11.

Impeller 4 is by wheel disc and constituting at four uniform blades of wheel disc one side in the above-mentioned framework, and the root of blade is the circular arc bending, and at a distance of the center hole certain distance of wheel disc.Blade top thickness is 4mm, and thickens downwards to 6mm gradually, makes impeller can reach best water absorption and water displacement, and strengthens impeller intensity.Pedestal 2 appearance integral body be processed with by center hole to around the stiffening rib 5 of radial distribution, not only effectively strengthened the intensity of pedestal but also reduced the use of material, make pedestal be connected firm more, weight saving, cost reduction with power.Outer casing inner wall has 12 semi-circular stiffening ribs 13, respectively there is at least one wedge shape stiffening rib 12 on four jiaos of mounting hole both sides of outer surface of outer cover, not only strengthened the intensity of shell, thereby and reduced material and used shock resistance enhancing, weight saving, cost reduction, beautiful shape.Be provided with the seal ring 7 of a band in the water intake 6, when suction cover makes water pump at priming petock, stop water to spill from water intake from suction cover, and prevent that when not using for a long time water leaks in the body, repeat when having avoided reusing to pour water, thereby saved workload, be easy to promote.Band is provided with long waist type raised line 11 from seal ring 7 roots of suction cover, and interior the making of groove that raised line snaps in water intake when mounted keeps good sealing effect from suction cover under long-time activity, and increased the lift of water pump.Water intake 6 bores make inflow further improve lift greater than water-outlet quantity greater than water outlet 3 bores.
