Kev lag luam zaub mov yog qhov tseem ceeb tshaj plaws ntawm tib neeg kev lag luam ua neej nyob, thiab nws txuas ntxiv mus "kho" nrog kev nce ntawm tib neeg kev xav tau. Kev xaiv zaub mov los ntawm tib neeg yog qhov tseem ceeb ntawm cov khoom noj. Txawm li cas los xij, ntau zaus cov khoom ntawm cov khoom noj nws tus kheej tsis tuaj yeem ua tau raws li cov kev xav tau ntawm kev ua haujlwm niaj hnub, uas yuav tsum tau hloov kho thiab ua haujlwm. Yog tsis hloov nws cov ntsiab lus, kev siv lub cev ua haujlwm tau ua lub luag haujlwm tseem ceeb hauv kev lag luam khoom noj.
Cavitation thev naus laus zis yog cov cuab yeej ua khoom noj khoom haus lub cev, uas siv lub zog muaj zog uas tsim los ntawm kev tawg ntawm cavitation npuas los txhim kho lub dav hlau yaig. Thaum lub sij hawm cavitation txheej txheem, lub sij hawm thaum lub cavitation npuas vau yuav ua rau lub zos huab cua instantaneous kub thiab siab siab, nrog rau cov muaj zog poob siab tsis, microjets, turbulence, thiab siab shear rog, uas yuav hloov cov qauv ntawm cov khoom thiab hloov cov khoom tus qauv. Ua cov yam ntxwv, xws li solubility, emulsification, rheology, thiab lwm yam. Ntxiv rau cavitation mechanism, cavitation tshuab kuj muaj thermal mechanism thiab mechanical mechanical. Tam sim no, muaj ob lub ntsiab ntawm kev siv ntau yam, ib qho yog ultrasonic tshuab thiab lwm yam yog hydraulic cavitation tshuab.
Ultrasonic cavitation technology
Ultrasound yog ib qho acoustic nthwv dej nrog lub zaus ntau dua 20kHZ, uas ua rau cov neeg kho tshuab kev co ntawm cov xov xwm hauv nruab nrab, yog li ua rau muaj kev cuam tshuam ntawm acoustic yoj thiab nruab nrab. Thaum cov kua molecular deb tshaj qhov tseem ceeb molecular deb ntawm cov kua, qhov yog tsim, thiab lub qhov yuav nyob rau hauv Nruam oscillation nyob rau hauv qhov kev txiav txim ntawm lub suab tsis) los yog vau. Thaum lub sijhawm ntuav cavitation npuas adiabatically shrinks kom vau, qhov chaw me me nyob ib ncig ntawm lub cavitation npuas tuaj yeem tsim kom muaj qhov kub thiab txias siab, nrog rau cov kev poob siab tsis muaj zog, yog li tsim tshwj xeeb rau lub cev thiab tshuaj.
Hydraulic cavitation technology
Hydraulic cavitation txhais tau hais tias thaum cov kua dhau los ntawm lub throttle element (xws li lub orifice phaj, venturi, thiab lwm yam), vim muaj kev cuam tshuam ntawm lub ntsiab rau cov kua dej, cov kua dej ntws yuav loj dua thiab lub siab txo. Thaum cov kua siab raug txo kom saturated vapor siab los yog txawm tias tsis zoo siab, vim muaj cov roj insoluble cores me me hauv cov kua, cov kua vaporizes thiab generates ntau ntawm cavitation npuas. Nrog rau kev rov qab sai ntawm lub siab nyob ib puag ncig cov kua, cov cavitation npuas tawg tam sim ntawd Extinguish, kom cov yam ntxwv ntawm cov ntaub ntawv cuam tshuam. Los ntawm ntau lub cavitation npuas tsim thiab kev ua haujlwm puas tsuaj, cov khoom tuaj yeem ua tiav qhov kev xav tau. Kev ua haujlwm ntawm hydraulic cavitation tshuab yog zoo ib yam li ntawm ultrasonic yoj. Nws lub zog yog qis dua li ntawm ultrasonic nthwv dej, tab sis nws cov cavitation tus nqi thiab lub zog efficiency yog siab dua li ntawm ultrasonic yoj.
Cov teebmeem ntawm ultrasonic cavitation thiab hydraulic cavitation yog tib yam, tab sis muaj qhov sib txawv ntawm daim ntawv thov scenarios. Hais txog daim ntawv thov, ultrasonic cavitation muaj ntau daim ntawv thov dav, thaum hydraulic cavitation tsuas yog siv tau rau "kua" cov ntaub ntawv. Lub cavitation tshuab tau tsim sai heev nyob rau hauv xyoo tas los no. Ntau txoj hauv kev tshiab xws li lub teeb cavitation thiab particle cavitation tau hloov mus rau qhov tsim tau tiag tiag. Nws xav tias yuav dhau los ua ib txoj hauv kev tseem ceeb hauv kev lag luam zaub mov yav tom ntej.
Expansion: Ultrasonic Khoom noj khoom haus-Ultrasonic ncuav mog qab zib txiav tshuab nyob rau hauv Ultrasonic Application hauv Food Industry.
