Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of good air-conditioning draught fan impeller of mobility that makes air.
The purpose of this utility model can realize by following technical proposal: air-conditioning draught fan impeller, comprise tubular wheel hub, the middle part of described wheel hub is fixed with mid-game, described mid-game and described wheel hub coaxially arrange, the two ends of described wheel hub are all fixed with end plate and described end plate and described wheel hub and coaxially arrange, it is characterized in that, between end plate described in two, be provided with some blades and described blade through described mid-game, the two ends of described blade are all connected mutually with described end plate, and the two ends of described wheel hub have the conical surface that past hub axis tilts.
The two ends of wheel hub have the conical surface that past hub axis tilts, and in use, air are had to good leading role, make air have good mobility.Simultaneously blade is through mid-game, and the two ends of blade are connected mutually with end plate respectively, has simple in structure and connects advantage comparatively easily.
In above-mentioned air-conditioning draught fan impeller, the middle part of described wheel hub has annular convex, and described mid-game is circular and is set on described wheel hub, and the end face of described mid-game is resisted against on described annular convex.The end face of mid-game is resisted against on annular convex, make mid-game can axially locating on wheel hub, there is the good advantage of locating effect.The import and export established angle of blade is optimized, and makes inner flow field more reasonable.
In above-mentioned air-conditioning draught fan impeller, described mid-game and described annular convex are connected by screw.Mid-game and annular convex are connected by screw, have advantages of to be connected firmly and easy to connect, and screw also can adopt other fastening piece.
In above-mentioned air-conditioning draught fan impeller, the two ends of described blade are connected with described end plate mutually by riveted joint.The two ends of blade are connected with end plate mutually by riveted joint, have comparatively firmly advantage of connection.
In above-mentioned air-conditioning draught fan impeller, the middle part of described wheel hub is provided with rotating shaft and described rotating shaft and described wheel hub and coaxially arranges, and the two ends of described rotating shaft all protrude from the outer side wall of corresponding described rotating disk.
In above-mentioned air-conditioning draught fan impeller, the quantity of described blade is 30-60 and is uniformly distributed centered by the axis of described wheel hub.The quantity of blade is 30-60 and is uniformly distributed centered by the axis of described wheel hub, makes air have larger turnover rate, has good using effect.
Compared with prior art, this air-conditioning draught fan impeller has the following advantages:
1, the two ends of wheel hub have the conical surface that past hub axis tilts, and in use, air are had to good leading role, make air have good mobility;
2, blade is through mid-game, and the two ends of blade are connected mutually with end plate respectively, has simple in structure and connects advantage comparatively easily;
3, the two ends of blade are connected with end plate mutually by riveted joint, have comparatively firmly advantage of connection;
4, the quantity of blade is 30-60 and is uniformly distributed centered by the axis of described wheel hub, makes air have larger turnover rate, has good using effect.
