Cov kev tshawb fawb muaj feem ntseeg tias ultrasonic athuter yog siv cov kua roj ua kom zoo nkauj, thiab ua kom muaj zog sib cais thiab tawg cov tee dej los ntawm qhov chaw. Raws li cov ultrasonic zaus nce, lub atomized tej yam ua thinner thiab finer. Feem ntau, hauv qab kev txiav txim ntawm kev co ultrasonic zaus, cov tee dej zoo tuaj yeem tau txais. Ib qho ntxiv, cov ntsiab lus ultrasonic zaus tuaj yeem tshem tawm lossis nyias tus ciam kub txheej txheej nyob ze ntawm cov cua sov hloov chaw, yog li txhawb kev kub hloov.
Cov txheej txheem sib txawv ntawm cov txheej txheem atomization yog siv, uas tuaj yeem raug cais raws li cov nyhuv hloov ntawm lub zog ntawm cov kua zaj duab xis nto. Cov txheej txheem kho tshuab lossis cov txheej txheem atomization, xws li ob-kua ativization, siv cov tshuab hluav taws xob ntawm cov kua kom nws tuaj yeem tawg hauv daim ntawv ntawm cov tee dej. Cov txheej txheem no xav tau lub zog ntau dua thiab tsis muaj kev tswj hwm qhov kawg thiab kev tshaj tawm ntawm cov tee dej.
Txawv los ntawm kev ua atomization ib txwm muaj, nws tuaj yeem muaj txiaj ntsig ntau dua thiab tsuas yog xav tau hluav taws xob hluav taws xob kis rau cov khoom siv hluav taws xob kom tsav tsheb tam sim no. Cov tee dej tsis muaj chaw txav chaw, tsuas yog cov neeg siv khoom siv zog siv hluav taws xob tsim los ntawm cov khoom siv hluav taws xob siv los tsim cov tee dej. Txij li thaum tsis muaj lub zog ntxiv ntxiv, tus mob hluav taws xob tsawg tuaj yeem ua tau zoo dua.
Qhov nruab nrab ntawm cov dej ntws los ntawm capillary peaks ntawm forfed cocation ntau zaus ntawm 10-800 kem), thiab kev sib raug zoo ntawm cov dej ntws hauv nruab nrab ntawm cov tee dej. DP=0.34} * 8π / ρf2
Capillary vuag thiab cavitation teebmeem
Lub zog ntawm ultrasonic atomization yog raws li capillary yoj cov nyhuv thiab cavitation cov nyhuv. Thaum ua yeeb yam ntawm 20khz atomizing taub hau nrog lub zog qis dua, nws yog pom tias muaj ib qho kev ua yeeb yam ib txwm muaj, nrog tib lub peaks thiab troughs ib cheeb tsam, hu ua vuag capillary. Qhov no tsis muaj zog hluav taws xob ua cov kev cuam tshuam saum npoo tsis muaj qhov tseeb droplet ejection.
Cavitation yog cov ntawv me me uas tsis tuaj yeem pom ncaj qha rau saum npoo ntawm atomizing lub taub hau nrog lub qhov muag liab qab. Ob qho sib txawv ntawm cov dej ntws tau pom los ntawm lub koob yees duab sijhawm, uas muaj kev sib tw muaj ntau dua, thiab ze rau cov dej ntws tsawg dua, qhov uas muaj kev cavitation tuaj yeem pom tau.
Kev tsim cov kab noj hniav nyob ze ntawm atomizer nto thiab hauv zaj yeeb yaj kiab ua kua thiab tom qab kev sib tsoo ntawm cov kab noj hniav hauv zos ntawm lub zog loj ntawm lub zog; Yog li, piv rau qhov kev nthuav dav qis uas pom tias muaj kev tawm tsam yoj, cov nyhititation yoj zoo heev nce qhov kev nthuav dav tshaj tawm. Nyob rau tib lub sijhawm, thaj chaw thaj tsam nyob ntawm cov kua ntawm lub taub hau atomizing lub taub hau txo, ua rau nws ntes nyuaj rau kev ntes cov capillary vuag nyob saum npoo.
