The present invention relates to a kind of axial type energy-saving blower fan.
Background technique
At present, centrifugal blower and axial-flow blower are all the widely used fluid machineries in modern industry field, for enterprise brings considerable economic benefit, have promoted industrial automated process.Centrifugal blower generally adopts the revolution of motor lower, and power of motor is large, and mutually more the more, centrifugal blower changes the flow direction of medium in airduct, and axial-flow blower does not change the flow direction of medium in airduct in power consumption.The former air quantity and blast all very large; The latter's air quantity and blast are all very low.The former installs more complicated; The latter installs simpler.The former is generally connected by axle with blower fan by motor, therefore there is power consumpiton at transmission process; Latter motors is generally in blower fan, and centrifugal blower is selected advantageously than the combination of axial-flow blower at Wind Volume and large blast.Under equal-wattage, adopt the axial fan of general conventional impellers cannot reach the equal air quantity of centrifugal fan and blast.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, to provide a kind of structure simple, easy for installation, the axial type energy-saving blower fan of ventilating and cooling successful.
Object of the present invention is achieved through the following technical solutions: a kind of axial type energy-saving blower fan, comprise main wind tube, wind inlet section, wind outlet section, wind outlet section is provided with outlet housing, be inner core in main wind tube, have motor in inner core, above motor, be provided with heat radiation air intake pipe, motor is connected with impeller, impeller comprises center drum and multiple blade, the equal rotary setting of each blade, and the angle of swing α of each blade is 23-47 °.
Further improvement of the present invention is: wind inlet section comprises air intake cylinder, support plate, flange, the intake grill of taper and import cover.
Further improvement of the present invention is: wind inlet section comprises back-up ring on air intake cylinder, support plate, flange, support plate, the intake grill of hemisphere type and import cover.
Further improvement of the present invention is: be provided with motor outlet wire pipe and connection box for motor outside main wind tube.
The present invention compared with prior art has the following advantages: the present invention replaces conventional impellers by special purpose impeller, just can realize in equal air quantity, blast situation, compare all power of motor of centrifugal fan and want little by 43% ~ 50%, thus energy-saving and cost-reducing effect can be reached.
