Abstract
The utility model relates to a centrifugal impeller for a water pump, which comprises a circular double-layer cover plate, and an interlayer of the double-layer cover plate is clamped with curved blades. The utility model has the essential proposal that the outer end of each curved blade is provided with a small segment of radial straight blade, and/or radial short straight blades are clamped between two adjacent curved blades on the edge of the cover plate, and/or a volute groove passage is arranged between two adjacent water outlets on the outer side surface of the edge of the cover plate. The design is reasonable, a centrifugal water pump keeps the characteristic of large flow and also obtains the advantage of high lift of a volute pump, and the utility model is particularly suitable for a small water pump.
Description
The utility model belongs to the pump technology scope, relates to a kind of impeller of water pump.
The Centrifugal water pump of prior art, its impeller accompanies curved vane between its double-layer cover plate, because these curved vane are bend in one direction, therefore, though cause Centrifugal water pump that bigger flow is arranged, lift is less.And existing vortex type water pump, though lift is high, its flow is less, all be difficult to satisfied should flow big to water pump, the high requirement of lift again.
Task of the present utility model provides a kind of novel Centrifugal water pump impeller, makes water pump reach the purpose that flow is big, lift is high, thereby overcomes the above-mentioned deficiency of existing in prior technology.
Task of the present utility model is to improve to realize on the basis of existing Centrifugal water pump impeller, it comprises circular double-layer cover plate, the cover plate center, and one side has axis hole, another side has water intake, outer rim has water outlet, accompanies curved vane between two-layer cover plate, and its main points are that the outer end of these curved vane is a straight radial blade, and/or between the adjacent flex blade, accompany radially short prismatic blade in the edge of cover plate, and/or between adjacent water outlet, on the outer side surface of the edge of cover plate, be equipped with the vortex conduit.
Fig. 1 is a plan view of the present utility model
Fig. 2 is the A-A sectional view among Fig. 1
Below in conjunction with accompanying drawing the utility model is elaborated:
According to Fig. 1, shown in Figure 2,5 is circular double-layer cover plates among the figure, the cover plate center, and one side has axis hole 4, another side has water intake 7, outer rim has water outlet 2, accompanies curved vane 3 in the interlayer of cover plate 5, and the outer end of these curved vane 3 is a bit of straight radial blade, and/or 3 of adjacent two curved vane, be folded with radially short prismatic blade 1 in the edge of double-layer cover plate 5, and/or 2 of adjacent water outlets, on the outer side surface of the edge of cover plate 5, be equipped with vortex conduit 6.3 of the outer end one-tenth straight radial blade of above-mentioned curved vane 3 and two adjacent curved vane are established radially short prismatic blade 1 at the edge of double-layer cover plate 5 folder, all help increasing the power of stirring to water, strengthen hydraulic pressure, improve lift.2 of two adjacent water outlets make vortex conduit 6 on the outer side surface of the edge of cover plate 5, make the water of going out impeller enter pump housing volute chamber after, again and then add maelstrom, in order to improve lift.Above-mentioned three aspect combinations, acting in conjunction can realize that lift further improves.
The utility model modern design, rational in infrastructure, can make centrifugal water pump Guaranteeing under the big condition of flow to possess again high excellent of whirl type water pump lift Point is particularly suitable for using at small pump.
