Qhov siab dua qhov zaus ntawm Ultrasonic tu tshuab hauv chav kuaj, qhov zoo dua?

Laboratory ultrasonic tu tshuab yog ib yam tshiab ntawm cov khoom siv tu tsim rau cov kev xav tau ntawm kev huv huv hauv chav kuaj. Nws tuaj yeem paub qhov tsis siv neeg tu ntawm ntau yam kev sim iav thiab cov cuab yeej precision, daws qhov tsis zoo ntawm kev tu ib txwm siv, uas siv sijhawm ntev thiab ua haujlwm hnyav, thiab cov nyhuv nyuaj rau kev tswj. Nws kuj tseem tuaj yeem tiv thaiv cov kws tshawb fawb los ntawm kev cuam tshuam rau cov tshuaj tua kab mob tsis zoo, thiab ua lub luag haujlwm hauv kev txhim kho lub chaw kuaj xyuas ib puag ncig.

Raws li peb txhua tus paub, kev tu ultrasonic yog ua raws li cov nyhuv cavitation, uas yog ib qho tseem ceeb los txiav txim siab cov nyhuv ntawm ultrasonic tu, thiab ultrasonic zaus yuav cuam tshuam ncaj qha rau cov nyhuv cavitation. Yog li ntawd, ntau tus neeg yuav tsom mus rau qhov zaus thaum yuav cov tshuab ntxhua khaub ncaws ultrasound rau lub chaw soj nstuam. Peb txhua tus paub tias zaus yog tus naj npawb ntawm cov khoom siv ua tiav cov sijhawm hloov pauv hauv 1s. Dab tsi yog qhov ultrasonic zaus? Raws li lub npe cuam tshuam, nws hais txog cov xov tooj ntawm lub sijhawm lub suab nthwv dej ua tiav cov kev hloov pauv nyob rau hauv txhua thib ob, xws li 20KHz, uas yog, lub suab nthwv dej ua rau 20000 vibrations ib ob.

Vim tias cov khoom sib txawv thiab cov av yuav tsum tau ntxuav hauv ntau qhov kev lag luam, ultrasonic tu zaus siv kuj txawv. Qhov zaus ntawm ultrasonic thov nyob rau hauv tu teb yuav roughly muab faib ua tsawg zaus, nruab nrab zaus, siab zaus thiab mega zaus. Cov zaus feem ntau siv rau kev tu dav dav yog 28KHz, 40KHz, 68Khz, 80KHz, 120KHz, thiab lwm yam, ntawm 40KHz yog qhov siv ntau zaus hauv ntau yam lag luam. Tau ntsib nrog ntau qhov kev xaiv ntau zaus, qhov twg zaus ntawm lub tshuab nqus tsev ultrasonic siv hauv chav kuaj yog qhov tsim nyog dua?

Qhov siab dua qhov zaus ntawm ultrasonic tu tshuab hauv chav kuaj, qhov zoo dua? Cov nyhuv cavitation txo qis nrog qhov nce ntawm zaus. Qhov zaus yog tsawg, thiab cavitation yog yooj yim tshwm sim. Lub compression thiab rarefaction ntawm cov kua ntxuav muaj lub sij hawm ntev dua, yog li ntawd lub cavitation npuas yuav loj hlob mus rau ib tug loj loj ua ntej blasting, thiab ua rau kom cov cavitation siv. Nws yog feem ntau siv tau rau thaj chaw uas muaj adhesion siab ntawm kev ntxuav av thiab workpiece nto; High zaus ultrasound, ntawm qhov tsis sib xws. Nws tuaj yeem pom tias qhov nruab nrab thiab qis zaus feem ntau yog siv los ntxuav cov khoom loj ntawm cov av, nruab nrab thiab siab zaus yog siv los ntxuav micron nplai av, thiab megafrequency yog siv los ntxuav micron thiab submicron nplai av. Tom qab kev sim, cov hlab ntsha thiab cov twj paj nruag feem ntau muaj cov av ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw. Yog li ntawd, nyob rau hauv lub chaw soj nstuam, sib txawv ultrasonic zaus ob peb ua ke yuav raug xaiv raws li cov kev xav tau kev tu kom ua tiav qhov zoo tshaj plaws tu nyhuv.
