The imperfection of property and injection molding process, front shroud of impeller, blade and the part of back shroud of impeller three, impeller protecgulum are divided into by impeller
The difference injection moulding of plate, blade and back shroud of impeller, then by ultrasonic bonding by front shroud of impeller, blade and back shroud of impeller
Be made a finished product impeller, but generally existing not prison welding is consolidated after welding, there is that weld is coarse, burr is more, intensity not
The defect such as enough, leverages the performance and its service life of water pump.
The content of the invention
The purpose of this utility model is to provide that a kind of intensity is high, long service life pump blade wheel structure.
What the purpose of this utility model was realized in：
A kind of blade wheel structure of pump, including front shroud of impeller and back shroud of impeller, on the leading flank of the back shroud of impeller
Blade is provided at circumferentially spaced, the front end face of partial blade sets fluted along length of blade direction, after front shroud of impeller
The raised rib with groove interference fit is circumferentially arranged at intervals with side, the rib insertion impeller bonnet on front shroud of impeller
Pass through interference fit or/and ultrasonic bonding connection in groove on plate.
In the above-mentioned technical solutions, described blade is the leaf being disposed in radioactivity on the preceding surface of back shroud of impeller
Piece, described blade includes spaced blade one and blade two, the length of the length ＜ blades one of blade two.
In the above-mentioned technical solutions, described blade one and blade two is near the end of the centre bore of back shroud of impeller
To the arcuate structure of equidirectional bending.
In the above-mentioned technical solutions, it is provided with the back shroud of impeller between described adjacent blade one and blade two
Blade three, the length of the length ＜ blades two of blade three.
In the above-mentioned technical solutions, described groove is arranged on the front end face of described blade one.
In the above-mentioned technical solutions, described front shroud of impeller, back shroud of impeller and blade are made by engineering plastics.
The utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
1st, after front shroud of impeller of the present utility model and back shroud of impeller are mutually fastened, rib and groove interference fit, leaf
Integral by ultrasonic bonding between wheel front shroud and back shroud of impeller, weld is attractive in appearance and smooth, can effectively solve welding
Problem more than place's burr, is greatly improved the intensity of impeller, extends the service life of impeller.
