Detailed Description

Referring to fig. 1 and 2 and fig. 3 and 4, a novel impeller with low noise and high efficiency;

the axial-flow impeller comprises a fixed rim 1, wherein one side of the surface of the fixed rim 1 is fixedly connected with a plurality of groups of blades 2, one side of the inner wall of each blade 2 is fixedly connected with a reinforcing rib, one side of the surface of each blade 2 is fixedly connected with an installation outer ring 3, when the axial-flow impeller is used, one installation outer ring 3 is additionally arranged on the conventional impeller blade 2, and the radial single-side gap between the conventional axial-flow impeller and a blade cylinder ring is one-five to three-five percent of the impeller diameter when the conventional axial-flow impeller rotates; the novel impeller with low noise and high efficiency has the advantages that the blades 2 and the outer ring are integrated, the radial unilateral gap is zero relative to the conventional impeller, the loss of airflow is reduced, the noise is reduced by two to three decibels, the efficiency of the fan is generally improved by three to five percent, the outer ring can overcome certain centrifugal force of the blades 2, the whole impeller becomes an integral structure, the impeller has more advantages when overcoming axial force, the stability is stronger, one side of the surface of the outer ring 3 is fixedly connected with an anti-skidding sleeve, one side of the inner wall of the fixed rim 1 is fixedly connected with a fixed radial plate 4, the middle part of the inner wall of the fixed radial plate 4 is provided with a fixed groove 5, one side of the inner wall of the fixed groove 5 is spliced with a connecting shaft sleeve 6, the middle part of one side of the connecting shaft sleeve 6 is provided with a mounting groove 7, one side of the inner wall of the mounting groove 7 is provided with a connecting groove 8, one side of the inner wall of the mounting groove 7 is fixedly connected with a fixed sleeve plate, and both sides of the surface of the connecting shaft sleeve 6 are provided with threaded holes 9, an arc-shaped groove is formed in one side of the inner wall of the threaded hole 9;
