Unveiling Cov Ua Haujlwm Tsis Paub Ntawm Ultrasonic Atomizing Nozzles

Nyob rau hauv siab -kawg teb xws li precision manufacturing, biomedicine, tshiab zog, thiab kev ua lag luam, ultrasonic atomizing nozzles yog maj mam hloov cov tsoos siab- hom thiab huab cua- pab nozzles, ua cov khoom tseem ceeb rau kev ua tau zoo, meej, thiab ib puag ncig tus phooj ywg atomization. RPS-SONIC, tshwj xeeb hauv kev siv siab- lub zog ultrasonic, yog tus kws tshaj lij ntawm cov thev naus laus zis no. Txij li thaum nws pib, RPS-SONIC tau tsom mus rau "cov khoom lag luam tsom thiab kev pabcuam siab" raws li nws cov txiaj ntsig tseem ceeb, kev cog qoob loo ntawm ultrasonic atomization teb thiab tsim kom muaj ntau yam ntawm atomizing nozzles npog ntau yam xwm txheej thiab kev xav tau. Nws cov khoom, nrog rau lawv cov qauv tsim tshwj xeeb, kev ua tau zoo ntawm atomization, thiab kev hloov pauv dav dav, raug xa tawm mus rau ntau dua 30 lub teb chaws thoob ntiaj teb, dhau los ua tus nyiam koom tes rau ntau lub tuam txhab.

 

I. Txoj Cai Ua Haujlwm ntawm Ultrasonic Atomizing Nozzles (General Logic)

Lub ntsiab ntawm lub ultrasonic atomizing nozzle yog ib tug precision ntaus ntawv rau "lub zog hloov dua siab tshiab thiab hloov." Nws cov ntsiab lus tseem ceeb ua haujlwm yog nyob ib puag ncig lub zog hloov pauv ntawm "hluav taws xob- suab- kua." Ultrasonic atomization rhuav tshem cov kev sib cuam tshuam ntawm cov kua los ntawm siab - zaus txhua yam kev co, ua kom muaj kev sib haum xeeb thiab zoo li atomization-ib qho "ntsuab atomization" thev naus laus zis. Nws ua tiav kev ua haujlwm tuaj yeem muab faib ua tsib theem tseem ceeb, txhua qhov sib cuam tshuam, sib sau ua ke txiav txim siab qhov tseeb thiab ruaj khov ntawm cov nyhuv atomization.

 

1.1 Lub Zog Pib-nce: Tsim Cov Hluav Taws Xob Siab Siab-Frequency Electrical Signals
Thawj kauj ruam hauv ultrasonic atomization yog hloov pauv lub zog hluav taws xob zaus hluav taws xob hluav taws xob (110/220V, 50/60Hz) rau hauv siab - zaus hluav taws xob teeb liab. Cov txheej txheem no yog ua tiav los ntawm lub tshuab hluav taws xob ultrasonic (power supply module) 配套 nrog lub nozzle. Raws li "faiv fab chaw" ntawm tag nrho cov kab ke, lub tshuab hluav taws xob, los ntawm kev tswj hwm ntawm nws qhov kev txiav txim siab hauv Circuit Court, hloov lub zog zaus hluav taws xob mus rau hauv siab - zaus hluav taws xob teeb liab nrog zaus ntawm 20kHz thiab 180kHz-ntau zaus ntau tshaj li qhov txwv ntawm tib neeg lub rooj sib hais, yog li tsis muaj kev cuam tshuam cov khoom siv hluav taws xob. kev vibration.

 

1.2 Lub zog hloov pauv: Lub luag haujlwm tseem ceeb ntawm Piezoelectric Effect
Tom qab qhov siab - zaus hluav taws xob teeb liab raug tsim tawm, nws yuav tsum tau hloov los ntawm "hluav taws xob" mus rau "txoj kev vibration zog" los ntawm "piezoelectric transducer." Qhov no yog lub hauv paus ntawm ultrasonic atomization thiab ib qho ntawm qhov sib txawv tseem ceeb ntawm RPS -SONIC nozzle thiab cov nozzles zoo tib yam. Thaum lub siab - zaus hluav taws xob teeb liab raug siv rau lub piezoelectric ceramic, cov ceramic ua rau lub sij hawm txhua lub sij hawm expansion thiab contraction. Cov zaus sib cog lus zoo kawg nkaus phim qhov zaus ntawm cov teeb liab input hluav taws xob, yog li tsim kom muaj siab - zaus mechanical vibration.

 

RPS-SONIC tau tshwj xeeb kho nws cov piezoelectric transducer, siv ntau- txheej piezoelectric ceramic tsim. Qhov no tsis yog tsuas yog ua kom lub zog hloov pauv mus rau ntau dua 95% thiab txo lub zog poob, tab sis kuj ua kom ntseeg tau, los ntawm cov qauv impedance zoo sib xws, tias cov hluav taws xob hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob raug xa mus rau lub transducer mus rau qhov siab tshaj plaws, tsis txhob siv hluav taws xob pov tseg. Nyob rau tib lub sijhawm, lub transducer suav nrog cov qauv hluav taws xob muaj txiaj ntsig zoo, txo cov cua sov uas tsim los ntawm lub sijhawm ntev - zaus vibration thiab txuas cov khoom siv lub neej. Qhov no yog ib qho ntawm cov laj thawj tseem ceeb vim li cas RPS-SONIC nozzles tuaj yeem ua tiav kev ua haujlwm tsis tu ncua thiab ruaj khov.

 

1.3 Vibration Amplification: Precise Enabling of the Amplifier Tus thawj vibration amplitude generated los ntawm piezoelectric transducer yog me me (feem ntau tsuas yog ob peb micrometers), tsis txaus rau cov kua atomization ncaj qha. Nws yuav tsum tau amplification los ntawm lub amplifier (tseem hu ua lub horn). Lub luag haujlwm tseem ceeb ntawm amplitude transformer yog los hloov qhov qis - amplitude, siab - quab yuam kev vibration ntawm lub transducer mus rau siab -amplitude, qis- quab yuam kev co, thaum precisely xa cov vibrational zog mus rau lub atomizing ntsis ntawm lub atomizing nozzle.

 

1.4 Liquid Atomization: Capillary Wave Breakup thiab Droplet Tsim

Thaum lub amplified siab - zaus vibration yog kis mus rau lub atomizing tip, cov kua ntws maj mam mus rau saum npoo ntawm lub atomizing tip nyob rau hauv lub laminar flow xeev los ntawm lub ntiajteb txawj nqus noj los yog ib tug tsawg - siab peristaltic twj tso kua mis (0.1-5 psi), ua ib tug ultra-} 10 μm tuab zaj duab xis (10) At this time, the high-frequency vibration generates stable "capillary standing waves" on the surface of the liquid film-a periodic ripple whose wavelength is determined by the ultrasonic frequency, liquid density, and surface tension, following the Kelvin-Helmholtz instability equation.

 

Raws li qhov kev vibration amplitude tseem nce ntxiv, lub ncov ntawm capillary sawv nthwv dej maj mam nce. Thaum lub amplitude nce mus txog tus nqi tseem ceeb (feem ntau yog 10-20% ntawm lub wavelength), qhov nro ntawm qhov chaw tsis tuaj yeem txhawb nqa qhov hnyav ntawm lub ncov, ua rau nws tawg thiab tshem tawm ntawm nws lub taub, tsim suav tsis txheeb me me, cov dej tsis sib xws. Cov txheej txheem no yuav tsum tsis txhob muaj kev kub ntxhov; droplet tiam yog tag nrho ntawm lub zog vibrational. Yog li ntawd, cov txheej txheem atomization yog maj mam thiab tsis ua rau cov kua muaj pes tsawg leeg (tshwj xeeb tshaj yog haum rau cov khoom siv roj ntsha thiab cov ntaub ntawv kub-rhiab), thiab cov tee dej yog qhov sib npaug ntawm qhov loj me uas tsis muaj cov khoom loj loj.

 

1.5 Droplet Control: Cov Ntsiab Cai ntawm Kev Tswj Kom Zoo
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm ultrasonic atomization yog qhov kev tswj xyuas meej ntawm cov tee me me, uas yog ua tiav los ntawm kev hloov pauv zaus - zaus thiab cov tee dej loj yog qhov cuam tshuam tsis zoo: qhov ntau dua, qhov me me ntawm cov tee dej; qhov tsawg zaus, qhov loj dua cov tee dej. Tsis tas li ntawd, qhov viscosity thiab qhov nro ntawm cov kua kuj cuam tshuam rau cov dej loj. RPS-SONIC, los ntawm kev tsim cov cuab yeej siv tau zoo, tuaj yeem tiv thaiv kev cuam tshuam ntawm cov xwm txheej no, ua kom muaj kev ruaj ntseg ntawm cov nyhuv atomization.

 

Piv txwv li, rau siab -cov kua viscosity (50-1000 cP), RPS-SONIC tuaj yeem txo cov kua viscosity thiab ua kom cov atomization zoo ib yam los ntawm kev txo qis zaus, nce qhov kev vibration amplitude, los yog siv lub rhuab atomizing taub. Rau qis-nto- cov kua nplaum, qhov adhesion ntawm cov kua thiab lub taub tuaj yeem txhim kho los ntawm kev ua kom zoo dua qhov roughness ntawm atomizing taub, yog li tiv thaiv cov kua txaws. Qhov kev tswj tau yooj yim no tso cai rau RPS-SONIC nozzles hloov mus rau ntau hom kua thiab ua tau raws li ntau hom kev xav tau.
