Embodiment Construction
[0010] figure 1 , 2 Shown is an extruded hollow aluminum profile wing blade impeller, including a shaft disk 1, a blade 5, a backing plate 4 and a petiole 2, the blade 5 is an extruded wing-shaped hollow aluminum profile, and the inside of the blade is provided with a There are multiple reinforcing ribs extending in the shape of the wing. The inner side of the blade 5 is locked and connected to the petiole 2 through the bolt through the backing plate 4. The tail of the petiole 2 is the shank 3. Multiple radial The petioles 2 of a plurality of connecting leaves 5 are inserted into the openings through the handles 3, and the petioles are connected to the shaft disk 1 by the pressing plates 6 on the front and rear sides of the disc through the bolts to press the petioles.

The invention relates to an extruded hollow aluminum profile wing blade impeller. The extruded hollow aluminum profile wing blade impeller is characterized by comprising a shaft disc, blades, a base plate and blade handles; the blades are extrude-formed wing-shaped hollow aluminum profiles, a plurality of reinforcing ribs extending in the length direction of the shape of a wing are arranged in the blades, the inner side edges of the blades are locked and connected to the blade handles in the mode that bolts are in cross connection with the base plate, and the blade handles connected with the blades are evenly distributed, locked and connected to the round periphery of the shaft disc. The weight of the impeller made from the extruded hollow aluminum profile 210 wing blades is only 50%-70% of that of an original cast aluminum impeller, the wing section performance coverage range is wide, the secondary mounting angles of the blades are adjustable through the blade handles, the impeller can be easily adapt to designing and producing marine fans of different working condition requirements easily, and the impeller has more remarkable advantages on the difference between the octave frequency band pressure level of the impeller and the octave frequency band pressure level of the original cast aluminum impeller.
Description
technical field [0001] The invention relates to an impeller, in particular to an extruded hollow aluminum profile wing blade impeller. Background technique [0002] With the development of the ship industry, ship ventilation equipment is more and more valued by customers. The impeller made of traditional wing blades is heavy, and the airfoil blades are integrally cast or forged, which is difficult to process and high in cost, and is not conducive to improving the efficiency of the impeller. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an extruded hollow aluminum profile wing blade impeller with convenient processing, light weight and low cost. [0004] The technical solution of the present invention is: an extruded hollow aluminum profile wing blade impeller, which is characterized in that it includes a shaft disk, a blade, a backing plate and a petiole, and the blade is an extruded wing-shaped hollow aluminum profi...
