Description
Technical field
The utility model relates to electric motors, relates in particular to alternating current series motor.
Background technology
The development trend of dust catcher is the control of dust amount to high air quantity, high vacuum, raising unit volume, reduces noise, and a tractor serves several purposes and operation automation direction develop.Motor of dust collector is the heart of dust catcher, and the main kind of motor of dust collector has: do and inhale motor of dust collector (THRU-FLOW), do wet motor of dust collector (BY-PASS).Motor of dust collector is made up of two parts: motor part and blower fan part; Because it is very high that motor of dust collector requires rotating speed,, be series excitation class motor so motor mainly adopts generally at 20000-30000 rpm; Be called series machine again; Its quality quality, bigger to the complete machine quality influence, or even critical.Though China has formed fairly large dust catcher production capacity at present, the ratio that uses the motor of totally-domestic is few.The motor of dust collector production domesticization is imperative.High-performance, low noise, long-life will be the motor of dust collector Development Trend.
Series-wound motor mainly is made up of stator, rotor, forward and backward end cap (cover) and blower fan.Blower fan partly mainly contains two critical pieces: movable vane wheel and decide impeller, and the movable vane wheel mainly is to produce wind, when the movable vane wheel was rotated with 20000-30000 rpm high rotating speed, the air inlet place can produce negative pressure shape and become vacuum, and then formation suction; Decide impeller, be called inducer again, main effect is more smooth-going the discharging of air quantity that makes that the movable vane wheel produces, and decides the quality in impeller air channel, directly influences the efficient of motor of dust collector.
The range of application of motor of dust collector: various family expenses industrial dried suction dust catcher, Wet-dry dust catcher, central dust extractor, industrial dust collector and various types of sweeper.In fact, motor of dust collector is not limited to and is applied on the dust catcher, and for example bubble is bathed, spray paint, and the artificial snowflake of stage, air pump, pet does the hair device, and hand dryer agricultural machinery or the like needs the equipment of suction.The motor of dust collector of function admirable will promote the performance of these electric equipment products greatly and increase the service life.
The utility model content
The purpose of the utility model is to provide a kind of improved motor of dust collector, characteristics such as it has, and volume is little, efficient is high, superior performance, life-span length.
To achieve these goals; The utility model has adopted following technical scheme: a kind of dust catcher is used alternating current series motor; Comprise rotor assembly, field frame assembly, movable vane wheel, decide impeller and fan housing, said movable vane wheel is provided with 11 fan blades, and said fan blade is a curve of the blade.The movable vane wheel is the vitals that produces air quantity and noise; The utility model fan blade adopts curve of the blade, and disposes best fan blade quantity, lets steadily smooth the passing through of high velocity air; Thereby the flow that reaches air draught is big; Again because of not disorderly between the air-flow, reach each other with the runner inner wall friction and reach minimum, so the noise that produces is minimum.
Said fan housing is provided with a cannelure in the inlet scoop, and the air intake vent of said movable vane wheel has a circle raised brim, and said raised brim is embedded in the said cannelure, and packing has the silica gel sealing ring of being close to said air intake vent raised brim in the said cannelure.This silica gel sealing ring matches with the raised brim of movable vane wheel, reaches the purpose of sealing, prevents that the high speed and high pressure air-flow is revealed in the fan housing, and then increases air quantity.
Said fan housing outer wall stamps out the two-stage boss.This structure has improved the mechanical strength and the rigidity of fan housing greatly, and then has increased fan housing and movable vane wheel, decide the quality of fit of impeller, motor case etc., has reduced the noise because of fan housing distortion, resonance generation simultaneously.
Saidly decide the wind wheel periphery and be provided with upper strata blade and lower leave, constitute double-deck wind deflector, two-layer blade is respectively clockwise and the curve of the blade of counterclockwise arranging, and is provided with gas channel between the two-layer blade.The principle of the curve of blade design aerodynamic is guaranteed the air-flow that the movable vane wheel is produced up and down, has no resistance, the no remaining lower leave that exports to, and prevents to produce backflow, turbulent flow, power attenuation is dropped to minimum.This blade construction is reasonable in design, avoids producing turbulent flow and backflow, thereby has avoided between the air-flow because of colliding vibration and the noise that is produced each other.
Said upper strata blade and lower leave respectively have 15.The quantity of blade, and blade shape etc. all with the best mode configuration, to reach best air intake effect.
The utility model improves through fan housing, air channel, fan blade quantity, fan blade being arranged etc., has reduced air flow losses, improves electric efficiency.Runner design is simultaneously gone up and is adopted silica gel sealing, improves electric efficiency; Compare with similar motor have the efficient height, volume is little, performance is good advantage.The utility model has significantly reduced windage, has reduced the air quantity loss; And then reduced the kinetic equation loss of motor; Air quantity, the efficient of dust catcher had both been improved; Reduced again brush loss, reduced temperature rise, reduced noise, thereby reached the comprehensive mechanical that improved motor and the purpose of electric property, the life-span of motor surpasses 600 hours, noise is lower than 80dB.
Through detecting, can reach effect like table 1:
