Abstract
The invention relates to a blower comprising a high-speed permanent-magnet machine and a blower body, wherein the rotor of the high-speed permanent-magnet machine is fixedly connected with the impeller of the blower body; the rotor of the high-speed permanent-magnet machine and the impeller of the blower body can rotate synchronously; the impeller is arranged in the housing of the blower body; large blades and small blades are mounted on the impeller alternately; the housing of the blower body is connected with that of the high-speed permanent-magnet machine; an annular air cavity is formed in the housing of the blower body; an inlet duct communicated with the annular air cavity is arranged on the housing of the high-speed permanent-magnet machine; the housing of the blower body takes the shape of a volute; a swirl-shaped air passage is arranged in the housing of the blower body; one side of the swirl-shaped air passage is communicated with the annular air cavity; and the other side of the swirl-shaped air passage is communicated with a gassing bent pipe. The blower provided by the invention has the advantages that the reliability of the rotor is high; the mounting and the processing are simple; the size is small; the efficiency is high; the starting current is small; and the wind volume adjusting is convenient.
Description
Technical field
The present invention 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, processing and installation complicacy, and volume is big, and efficient is low, and starting current Da Yi forms impact to electrical network, the difficult adjusting of air quantity size.
Summary of the invention
It is reliably good to the purpose of this invention is to provide a kind of rotor, promptly installs and process the blower simple, that volume is little, efficient is high, starting current is little and air quantity is easy to adjust.
Technological scheme of the present invention 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, and alternatively distributed big blade and small leaf are installed on the impeller, and the quantity of big 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, and electric machine casing is provided with intake duct and communicates with annular air cavity; Blower Housing is a volute shape; Set inside has an eddy flow shape air flue and a side to communicate with annular air cavity, and 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 big blade and small leaf preferably is respectively 11.
The present invention adopts high-speed permanent magnet motor: like patent 201020502094.X as power source; Change more than the scooter 30000r/min; Therefore can just can directly reach the requirement of rotating speed without devices such as speedup boxes; Adopt motor and blower fan direct connection, installation 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 present invention 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 invention also has adjustable advantage.Blade of the present invention is many; Therefore increased working efficiency, blade is that size alternately distributes simultaneously, and small leaf can suppress even eliminate heavy camber blade blade back airflow breakaway; Avoid conventional method to increase blade simultaneously and cause the anterior air-flow of conduit to stop up, help the raising of impeller adiabatic efficiency; And small leaf is not influencing under the flow rate condition, has improved the amount of finish of impeller second half section, 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 bleed valve adjustment.Electric machine casing is provided with intake duct, can effectively cool off high-speed permanent magnet motor.
