Abstract
The utility model relates to the field of ventilating equipment, and discloses a metal centrifugal impeller. The metal centrifugal impeller comprises a metal front ring, a metal base plate and a plurality of metal blades fixed between the metal front ring and the metal base plate. The metal front ring is composed of an inner ring and an outer ring which are connected as a whole. The outer end of the inner ring and the inner end of the outer ring are connected with each other as a whole. The outer ring is in an inclined shape with the interior low and the exterior high. The outer end of the outer ring tilts towards the direction away from the metal base plate, and the tilting angle is within 8-10 degrees. The metal centrifugal impeller has the advantages of being novel in structure, increased in air outlet area, and increased in air quantity.
Description
Technical field
The utility model relates to the ventilation equipment field, relates in particular to a kind of metal centrifugal impeller.
Background technique
Metal centrifugal impeller is ventilation equipment field product commonly used, its structure comprises circle, metal chassis before the metal and is fixed between the two a plurality of metal blades, external lateral portion and the metal chassis of circle are parallel to each other before the existing metal, be burnishing surface, be the exhaust outlet of centrifugal impeller between the external lateral portion of circle and the metal chassis before the metal, the area of exhaust outlet is the factor that determines the air force of centrifugal impeller.The deficiency that existing metal centrifugal impeller exists is that structure is single, and the exhaust outlet area is little.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to solve existing metal centrifugal impeller, provides a kind of novel structure, the metal centrifugal impeller that the exhaust outlet area is large.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of metal centrifugal impeller, comprise circle, metal chassis before the metal and be fixed between the two a plurality of metal blades, circle is made of the inner ring that is connected as a single entity and outer ring before the metal, inner ring outer end and the inner, outer ring are connected as a single entity, the outer ring is interior low outer high tilted shape, the outer end, outer ring is towards the direction perk away from metal chassis, and the angle of its perk is between the 8-10 degree.
Adopted a kind of metal centrifugal impeller of above-mentioned technological scheme, circle is made of the inner ring that is connected as a single entity and outer ring before the metal, the outer ring is interior low outer high tilted shape, the outer end, outer ring is towards the direction perk away from the chassis, and the angle of its perk is between the 8-10 degree, the advantage of this metal centrifugal impeller is novel structure, the area that has increased exhaust outlet has namely increased air quantity, under equal rotating speed, the flow that increases and pressure are about 6%, power consumption reduces 3%, namely can reach with lower rotating speed the requirement air quantity, and impeller is moving than under the slow-speed of revolution, the longer life-span can be arranged, and after rotating speed reduced, the impeller noise had also reduced about 3dB, and the metal centrifugal impeller of this structure can not increase manufacture cost.
Description of drawings
Fig. 1: the utility model embodiment's perspective view.
Fig. 2: the utility model embodiment's cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2 embodiment of the present utility model is made a detailed explanation.
A kind of metal centrifugal impeller as depicted in figs. 1 and 2, comprise circle 1, metal chassis 3 before the metal and be fixed between the two a plurality of metal blades 2, circle 1 is made of the inner ring 12 that is connected as a single entity and outer ring 11 before the metal, inner ring 12 outer ends and 11 the inners, outer ring are connected as a single entity, outer ring 11 is interior low outer high tilted shape, 11 outer ends, outer ring are towards the direction perk away from metal chassis 3, and the angle a of its perk is between the 8-10 degree.
The metal centrifugal impeller of above-mentioned structure, the angle a of outer end, outer ring perk are between the 8-10 degree, and the area that has increased exhaust outlet has namely increased air quantity.With respect to the metal centrifugal impeller of existing same model size under equal rotating speed, the flow that increases and pressure are about 6%, power consumption reduces 3%, namely can reach with lower rotating speed the requirement air quantity, and impeller is moving than under the slow-speed of revolution, and the longer life-span can be arranged, and after the rotating speed reduction, the impeller noise has also reduced about 3dB, and the metal centrifugal impeller of this structure can not increase manufacture cost.
Claims (1)
