Abstract
The utility model relates to an air blower, comprising a high speed permanent magnet motor and a blower fan, a high speed permanent magnet motor rotor and a blower fan impeller are fixedly connected and can synchronously rotate; the impeller is disposed in a blower fan housing, and is provided with big blades and small blades alternatively distributed, the blower fan housing is connected with the high speed permanent magnet motor housing, the internal of the blower fan housing is provide with an annular air chamber, the motor housing is provided with an air inlet channel communicated with the annular air chamber, the blower fan housing is in the shape of a spiral case, the internal is provided with an eddy flow airway with one side communicated with the annular air chamber, and the other side communicated with an air outlet bend pipe. The air blower is advantaged by good reliability of rotor, namely simple installation and machining, small volume, high efficiency, small startup current, convenient adjustment of air quantity, etc.
Description
Technical field
The utility model relates to a kind of blower.
Background technique
Under design condition, blast is 30kpa to 200kpa, and compression ratio is that 1.3 to 3 blower fan is called blower.The tradition high-speed blower adopts gear speedup case to make up slowspeed machine mostly, processes and the installation complexity, and volume is large, and efficient is low, and starting current Da Yi forms impact to electrical network, the difficult adjusting of air force.
Summary of the invention
It is reliably good that the purpose of this utility model provides a kind of rotor, namely installs and process the blower simple, that volume is little, efficient is high, starting current is little and air quantity is easy to adjust.
The technical solution of the utility model is, blower comprises high-speed permanent magnet motor and blower fan, and described high speed permanent magnet motor rotor and draught fan impeller connect firmly, and can rotate synchronously; Impeller is positioned at Blower Housing, alternatively distributed large blade and small leaf are installed on the impeller, the quantity of large blade and small leaf is respectively 10～12, Blower Housing is connected with the high-speed permanent magnet motor housing, be provided with annular flow deflecting cone in the Blower Housing, described flow deflecting cone is fixed on the electric machine casing and with Blower Housing and forms annular air cavity, be provided with intake duct on the electric machine casing and communicate with annular air cavity, Blower Housing is volute shape, inside is provided with eddy flow shape air flue and a side communicates with annular air cavity, opposite side communicates with the bend pipe of giving vent to anger, and also is provided with bleed valve on the described bend pipe of giving vent to anger.The quantity of described large blade and small leaf preferably is respectively 11.
The utility model adopts high-speed permanent magnet motor: such as patent 201020502094.X as power source, turn more than the scooter 30000r/min, therefore can just can directly reach without devices such as speedup boxes the requirement of rotating speed, adopt motor and blower fan direct connection, install and easy to process, volume is little and mass distribution is even, good reliability; The high-speed permanent magnet motor variable ratio frequency changer starts simultaneously, therefore can make the utility model little to the impact that electrical network forms when starting, and damages little; It is adjustable that motor also has the rotating speed frequency conversion, and therefore air quantity of the present utility model also has adjustable advantage.Blade of the present utility model is many, therefore increased working efficiency, blade is that size is alternately distributed simultaneously, and small leaf can suppress even eliminate heavy camber blade blade back airflow breakaway, avoid simultaneously conventional method to increase blade and cause the anterior air-flow of conduit to stop up, be conducive to the raising of impeller adiabatic efficiency; And small leaf has improved the amount of finish of impeller second half section under the condition that does not affect flow, improves the impeller overall pressure tatio.On the bend pipe of giving vent to anger, also be provided with bleed valve, can solve the surging phenomenon that blower occurs at work to bleed valve adjustment.Be provided with intake duct on the electric machine casing, can effectively cool off high-speed permanent magnet motor.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Blower Housing schematic diagram of the present utility model.
