Abstract
The utility model provides an impeller assembly for a suction centrifugal pump, which is arranged on the pump shaft of the suction centrifugal pump and comprises blades (2), a cover plate (3) and a wheel hub (4). The utility model is characterized in that the blades (2) are evenly disposed between the cover plate (3) and the wheel hub (4) at intervals; a water inlet (7) and a water outlet (8) are disposed between the cover plate (3) and the wheel hub (4); the center of the wheel hub (4) is provided with a pump shaft traversing and installing hole and a keyway (5); an inward-recessed deadweight relief groove is disposed in the wheel hub (4). The utility model has advantages of simple structure, complete functions, convenient processing and light weight.
Description
Technical field:
The utility model double-suction centrifugal pump relates to the double-suction centrifugal pump that is installed on the double-suction centrifugal pump pump shaft with the impeller sets zoarium and uses the fit field of impeller sets.
Background technique:
Double-suction centrifugal pump is mounted in the core component that on the double-suction centrifugal pump pump shaft liquid is provided power with the impeller sets zoarium, the double-suction centrifugal pump impeller sets zoarium of being made up of cover plate, blade and wheel hub that should design specialized.
Summary of the invention:
The purpose of this utility model provides a kind of double-suction centrifugal pump impeller sets zoarium, be formed with the double-suction centrifugal pump impeller sets zoarium of water intake and water outlet by between cover plate and wheel hub, adding some blades, in wheel hub, have pump shaft mounting hole and keyway, double-suction centrifugal pump can be installed on the double-suction centrifugal pump pump shaft with the impeller sets zoarium, after the pump shaft rotation, make liquid after blade increases power, export the purpose of going by water intake by water outlet to reach.
Double-suction centrifugal pump impeller sets zoarium, it is made up of blade, cover plate and wheel hub, and blade is formed with water intake and water outlet between cover plate and wheel hub between cover plate and wheel hub, have pump shaft mounting hole and keyway at the center of wheel hub, in wheel hub, have the weight reduction groove.
Double-suction centrifugal pump is to be connected with pump shaft by the key that is installed in its keyway with the impeller sets zoarium, after the motor driving pump shaft rotates, then double-suction centrifugal pump rotates with the impeller sets zoarium thereupon, liquid is entered by the water intake of double-suction centrifugal pump impeller sets zoarium, export by water outlet, make liquid after impeller flows, obtain energy, increased the pressure of liquid.
Double-suction centrifugal pump is positioned at circular pump shaft mounting hole outer edge side with the keyway in the impeller sets zoarium, and the pump shaft mounting hole is installed on the pump shaft.
Blade is uniform respectively to be distributed between cover plate and the wheel hub, and liquid flows out water outlet by water intake along blade.
In order to alleviate the deadweight of wheel hub, in wheel hub, have the weight reduction groove.
This double-suction centrifugal pump is simple in structure, multiple functional, easy to process with the fit advantage of impeller sets, from heavy and light.
Description of drawings:
Fig. 1: for double-suction centrifugal pump is looked cross-sectional schematic with the fit master of impeller sets.
Fig. 2: for double-suction centrifugal pump is looked cross-sectional schematic with the fit left side of impeller sets.
Embodiment:
Referring to Fig. 1 and Fig. 2, double-suction centrifugal pump impeller sets zoarium, it is made up of blade 2, cover plate 3 and wheel hub 4, blade 2 is between cover plate 3 and wheel hub 4, be formed with water intake 7 and water outlet 8 at cover plate 3 and 4 of wheel hubs, have pump shaft mounting hole 6 and keyway 5 at the center of wheel hub 4, in wheel hub 4, have the weight reduction groove.
As shown in Figure 2, double-suction centrifugal pump is the rectangle keyway with the keyway 5 in the impeller sets zoarium, is positioned at circular pump shaft mounting hole 6 outer edge sides, and promptly evagination is outside the pump shaft mounting hole 6 of circle.
6 blades, 2 uniform respectively being distributed between cover plate 3 and the wheel hub 4 are arranged, and liquid flows out water outlet 8 by water intake 7 after blade 2 superchargings.
In order to alleviate the deadweight of wheel hub 4, in wheel hub 4, have the weight reduction groove of indent.
