Dab tsi yog Qhov Peb Qhov Tseem Ceeb Ntawm Kev Tu Ntawm Ultrasonic Tu Tshuab?

1, ultrasonic zog nyhuv

Ultrasonic yoj muaj zog heev. Thaum nws kis tau hauv cov kua hauv xov xwm, nws hloov lub zog mus rau cov khoom siv xov xwm, uas tom qab ntawd hloov lub zog mus rau qhov chaw ntawm cov khoom tu thiab ua rau cov av dissociation thiab dispersion. acoustic nthwv dej yog ib tug longitudinal yoj, uas yog, kev co kev taw qhia ntawm cov xov xwm particle yog zoo ib yam nrog rau propagation ntawm lub nthwv dej. Nyob rau hauv tus txheej txheem ntawm longitudinal nthwv dej propagation, xov xwm ua rau uneven particle tis, particle motion nyob rau hauv lub ceev ntawm txawv cheeb tsam, nyob rau hauv lub cheeb tsam ntawm particle tis ntawm sparse suab tsis tsim lub siab tsis zoo, kev faib ntawm ntom ntom suab yoj daim ntawv yog suab siab. , thiab tsim ib qho kev hloov pauv tsis tu ncua ntawm qhov tsis zoo siab thiab kev hloov siab zoo, qhov kev hloov pauv no tsis tsuas yog ua rau cov xov xwm tau txais lub zog kinetic ntawm cov khoom thiab tau txais qee qhov nrawm. Lub zog ntawm - zaus ultrasound muaj zog heev. Thaum cov xov xwm hais nrog lub zog cuam tshuam nrog cov av, lawv hloov lub zog rau hauv av thiab ua rau lawv tawg thiab tawg.

2, acceleration: kua particles thawb lub acceleration generated. Rau lub tshuab ntxhua khaub ncaws ultrasonic nrog ntau zaus, cavitation tsis tseem ceeb, lub sij hawm no kev tu feem ntau yog nyob ntawm cov kua hais nyob rau hauv qhov kev txiav txim ultrasonic ntawm acceleration feem cuam tshuam rau ultra- precision tu av.

3, direct flow effect: ultrasonic nyob rau hauv cov kua raws cov kev taw qhia ntawm lub suab nrov tshwm sim yog hu ua direct flow. Thaum lub acoustic siv yog 0.5W/cm2, qhov muag liab qab tuaj yeem pom qhov ncaj qha ntws, uas yog perpendicular mus rau qhov chaw vibration, thiab tus nqi ntws yog li 10cm / s. Los ntawm qhov ncaj qha ntws, cov micro- roj av ntawm qhov chaw ntawm cov khoom ntxuav yog nplawm, thiab cov kua ntxuav ntawm cov av kuj tsim cov convection, thiab cov kua dej ntawm cov av yaj tau sib xyaw nrog cov kua tshiab, uas ua rau kom nrawm nrawm thiab ua lub luag haujlwm zoo hauv kev tuav cov av.
