Daim ntawv thov ntawm Ultrasonic Extractor

Ultrasound yog ib feem tseem ceeb ntawm cov acoustics. Nws tsuas yog kawm txog tiam, kev nthuav tawm, kev txais tos thiab kev cuam tshuam ntawm ultrasound hauv ntau yam tshuaj, ntau yam teebmeem thiab kev siv. Lub suab nthwv dej ntawm lub tshuab rho tawm ultrasonic belongs rau cov neeg kho tshuab nthwv dej, uas yog kev nthuav tawm ntawm txhua yam kev co hauv nruab nrab elastic. Niaj hnub no acoustics tau npog qhov ntau zaus ntawm 10-4 txog 1014Hz, uas yog sib npaug los ntawm infrasound vibrating ib zaug hauv li 3 teev rau molecular thermal vibrations nrog wavelengths luv dua lub atomic sib nrug hauv cov khib nyiab, uas yog, spanning ib tug dav zaus band ntawm lub kev txiav txim ntawm 1018. Qhov no kuj txhais tau hais tias, tam sim no, tib neeg tau paub txog cov cuab yeej siv niaj hnub no ntawm kev tsim thiab ntsuas cov suab nrov ntawm yuav luag txhua zaus.

Nyob rau hauv cov nqe lus ntawm ntau zaus, ultrasound hais txog lub suab nrog ntau zaus saum toj no ntau zaus ntawm lub suab nrov. Raws li txoj cai lij choj ntawm tib neeg pob ntseg, nyob rau hauv acoustics, lub sab sauv txwv ntawm lub zaus ntawm lub suab yog 2 104 Hz. Yog li feem ntau, ultrasound yog lub suab nthwv dej nrog lub zaus siab dua 20KHz. Yuav kom paub meej ntxiv, nyob rau hauv ultrasound zaus band, ultrasound nrog lub zaus siab tshaj 108 Hz yog hu ua hypersonic. Tshwj xeeb, 108-1012 Hz zaus band tseem hu ua microwave ultrasound vim nws sib raug rau microwave zaus band hauv electromagnetic spectrum.

Nyob rau hauv cov nqe lus ntawm lub hwj chim ntau ntawm ultrasonic extraction tshuab, nruam yoj ultrasonic feem ntau nyob rau hauv ntau yam ntawm milliwatts mus rau kaum ntawm kilowatts. Pulsed ultrasound tuaj yeem ntsuas qhov feem ntawm ib milliwatt mus rau ob peb megawatts. Raws li txoj cai, los ntawm qhov kev xav ntawm lub suab siv, qhov txwv sab saud ntawm kev tsom mus txuas ntxiv yoj ultrasound hauv cov kua yog txwv los ntawm cavitation, thiab qhov txwv sab saud tuaj yeem ncav cuag li kaum ntawm kilowatts ib square centimeter; thaum lub hom phiaj ntawm pulsed ultrasound nyob rau hauv nruab nrab ntawm lub focal chaw yuav txawm mus txog kaum tawm megabytes. Watts ib square centimeter. Obviously, ultrasound suav nrog cov ntsiab lus kev tshawb fawb nplua nuj nrog ntau qhov sib txawv ntawm cov kab mus rau nonlinear acoustics.

Los ntawm qhov kev xav ntawm qhov nruab nrab ntawm kev nthuav tawm, ultrasound tuaj yeem nthuav tawm hauv cov pa roj, kua, khib nyiab, khoom melts thiab lwm yam khoom. Hauv cov xov xwm no, ultrasonic nthwv dej ntawm ntau zaus, lub zog thiab kev siv zog muaj lawv cov yam ntxwv nthuav tawm thiab cov teebmeem, yog li lawv kuj muaj lawv cov ntsiab lus tshawb fawb thiab kev siv dav.
