Abstract
The utility model discloses a free-form surface ternary stream impeller of a vacuum machine. The free-form surface ternary stream impeller comprises blades, a wheel cover and a wheel disc, wherein the blades are uniformly arranged on an inner ring of the wheel disc, the wheel cover is arranged on the wheel disc and the blades, and the wheel cover is an annular cover plate. The free-form surface ternary stream impeller of the vacuum machine has the advantages that the air flow speed, the air flow distribution and flowing loss are small, the gas flowing loss is reduced, the efficiency of a centrifuge vacuum machine is improved, the energy consumption is reduced, and the fabricating cost is reduced.
Description
Technical field
The utility model patent relates to centrifugal vacuum machine technical field, is specifically related to a kind of vacuum machine free form surface three-dimensional flow impeller.
Background technique
Existing centrifugal vacuum machine impeller is generally the binary impeller, and the shortcoming of binary impeller is that efficient only has 75% left and right, efficient remote-effects on the low side vacuum machine institute distribution motivation bigger than normal, increased manufacture cost, not energy-conservation yet.
The model utility content
The purpose of model utility: the purpose of this utility model is in order to make up the deficiencies in the prior art, a kind of three-dimensional flow impeller that significantly improves efficient to be provided.
The technical solution adopted in the utility model: a kind of vacuum machine free form surface three-dimensional flow impeller, comprise blade, wheel cap and wheel disc, described blade is evenly arranged in the wheel disc inner ring, covers wheel cap between described wheel disc and blade, and described wheel cap is annular cover plate.
As optimization, described blade surface is free form surface.
As optimization, described blade is 22, tilts to install.
Beneficial effect: the utility model provides a kind of vacuum machine free form surface three-dimensional flow impeller, and its airspeed, air-flow distribute, flow losses are little, reduce the gas flow loss, improve centrifugal vacuum machine efficient, reduce energy consumption, reduce fabricating cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail:
A kind of vacuum machine free form surface three-dimensional flow impeller comprises blade 1, wheel cap 2 and wheel disc 3, and blade 1 is evenly arranged in wheel disc 3 inner rings, cover wheel cap 2 between wheel disc 3 and blade 1, wheel cap 2 is annular cover plate, and blade 1 surface is free form surface, blade 1 is 22, tilts to install; Under design conditions, its efficient is than high 15% left and right of binary impeller, and energy-saving effect is remarkable, greatly reduces manufacture cost.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
