Abstract
The utility model discloses an impeller, including wheel hub and a plurality of blades, blade and wheel hub periphery fixed connection, the last mesopore that is equipped with of wheel hub, wheel hub's cross -section is the concave arc face, the blade has vertical section and slope curved surface section, the slope curved surface section of a plurality of blade inclines to same direction, follows the contained angle A that the lower terminal surface of two blades that the central line is relative of wheel hub constitutes is 35~36, wheel hub's upper portion still is equipped with the annular table rank. The utility model discloses impeller work efficiency is high, accords with the principle of dynamics.
Description
Technical field
This utility model relates to a kind of impeller.
Background technology
Impeller uses widely, it is possible to as workmanship's element of gas, such as compressor etc.; Can also be workmanship's element of liquid, such as centrifugal pump etc. But all vertical with the hub centre line shape of the blade of existing impeller, so when wheel rotation, causes impeller inefficiency.
Summary of the invention
The purpose of this utility model is in that to provide a kind of impeller work efficiency high, meets the impeller of principle of dynamics.
In order to achieve the above object, the technical solution of the utility model is: a kind of impeller, including wheel hub and some blades, blade is fixing with hub periphery to be connected, wheel hub is provided with mesopore, the cross section of described wheel hub is cancave cambered surface, described blade has vertical section and tilts curved sections, the inclination curved sections of the blade of described some tilts to same direction, the included angle A that the lower surface of two blades that centrage along described wheel hub is relative is constituted is 35 �㡫36 ��, and the top of described wheel hub is additionally provided with ring-shaped step.
After adopting said structure, owing to the cross section of wheel hub of the present utility model is cancave cambered surface, described blade has vertical section and tilts curved sections, the inclination curved sections of the blade of described some tilts to same direction, and the included angle A that the lower surface of two blades that centrage along described wheel hub is relative is constituted is 35 �㡫36 ��. Therefore liquid or gas are through wheel hub, and wheel hub has streamlined structure, more smooth and easy. Blade, when rotating, tilts curved sections and can strengthen the power of impeller, and two relative vane have included angle A so that the resistance of impeller is little. Therefore impeller work efficiency is high, meets principle of dynamics. The top of wheel hub is additionally provided with ring-shaped step, is be connected with axle installation in order to convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the axonometric chart of Fig. 1.
Detailed description of the invention
This utility model is described in further detail by the embodiment provided below in conjunction with accompanying drawing.
Referring to Fig. 1, shown in 2, a kind of impeller, including wheel hub 1 and some blades 2, blade 2 is fixing with wheel hub 1 periphery to be connected, and wheel hub 1 is provided with mesopore 11, and the cross section of described wheel hub 1 is cancave cambered surface, described blade 2 has vertical section 21 and tilts curved sections 22, the inclination curved sections 22 of the blade 2 of described some tilts to same direction, and the included angle A that the lower surface of two blades 2 that centrage along described wheel hub 1 is relative is constituted is 35 �㡫36 ��, and the top of described wheel hub 1 is additionally provided with ring-shaped step 12.
Referring to Fig. 1, shown in 2, owing to the cross section of wheel hub 1 of the present utility model is cancave cambered surface, blade 2 is fixing with wheel hub 1 periphery to be connected, wheel hub 1 is provided with mesopore 11, the cross section of described wheel hub 1 is cancave cambered surface, described blade 2 has vertical section 21 and tilts curved sections 22, and the inclination curved sections 22 of the blade 2 of described some tilts to same direction, and the included angle A that the lower surface of two blades 2 that centrage along described wheel hub 1 is relative is constituted is 35 �㡫36 ��.Therefore liquid or gas are when through wheel hub 1, and wheel hub 1 has streamlined structure, more smooth and easy. Blade 2, when rotating, tilts curved sections 22 and can strengthen the power of impeller, and two relative vane 2 have included angle A so that the resistance of impeller is little. Therefore impeller work efficiency is high, meets principle of dynamics. The top of wheel hub 1 is additionally provided with ring-shaped step 12, is be connected with axle installation in order to convenient.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, under the premise creating design without departing from this utility model; can also making some deformation and improvement, these broadly fall into protection domain of the present utility model.
