Feem ntau yuam kev ntawm ultrasonic vuam tshuab hauv lub neej txhua hnub

1. Nkag siab cov tswv yim tsis ncaj ncees hauv txoj cai vuam
Qee cov neeg ua haujlwm uas tau koom nrog ultrasonic vuam rau ntau xyoo muaj kev xav tsis zoo txog kev sib kis ntawm ultrasonic zog. Lawv xav tias lub suab yoj vuam ntawm qhov chaw yog qhov tseeb. Lub hauv paus ntsiab lus ntawm vuam tiag tiag yog tias tom qab lub ultrasonic transducer hloov cov hluav taws xob hluav taws xob rau hauv lub zog hluav taws xob, kev sib kis tau ua tiav raws li cov qauv molecular ntawm cov tshuaj lom neeg ntawm lub workpiece. Lub acoustic tsis kam ntawm kev sib kis ntawm lub suab nthwv dej zaus hauv cov khoom hauv lub xeev yog qis dua li hauv huab cua. Thaum lub acoustic zaus raws li kev sib koom ua ke ntawm lub workpiece, lub acoustic kuj nyob rau hauv qhov sib txawv yog loj, uas ua rau lub thermal zog loj heev. Qhov kub ua ntej ncav cuag lub melting point ntawm lub workpiece, ntxiv rau ib tug tej yam kev ua hauj lwm siab, thiaj li hais tias lub sib koom ua ke yog fused, thaum lwm yam ntawm lub workpiece tsis yooj yim fused vim tsis muaj acoustic tsis kam thiab tsis kub. Nws txoj cai zoo ib yam li Ohm txoj cai.
2. Tsis yog lub tswv yim ntawm kev xaiv ultrasonic
Lub zog siv, oscillation zaus thiab amplitude ntau yuav tsum tau txiav txim siab raws li cov khoom siv raw ntawm lub workpiece, tag nrho cheeb tsam ntawm cov vuam kab, seb puas muaj cov khoom siv hluav taws xob hauv lub workpiece, thiab seb yuav tsum muaj huab cua nruj li cas. Nws kuj yog ib qho kev xav tsis zoo tias qhov siab dua qhov tso zis hluav taws xob, qhov zoo dua. Yog tias koj tsis paub ntau txog ultrasound. Nws yog qhov zoo dua los nrhiav tswv yim los ntawm cov kws tshaj lij cov neeg ua haujlwm ntawm engineering project ntawm lub chaw tsim khoom ultrasonic. Yog tias ua tau, nws yog qhov zoo dua rau kev sib txuas lus nrog cov chaw tsim khoom ntawm qhov chaw, yam tsis muaj qhov muag tsis pom kev thiab ua raws li kev dag ntxias ntawm qee tus neeg muag khoom tsis tu ncua ultrasonic.
Nyob rau theem tam sim no, cov lag luam uas tsim thiab tsim cov tshuab thiab cov cuab yeej siv tau tshwj xeeb yog qhov nyuaj. Feem coob ntawm lawv yog cov tsev neeg ua haujlwm me me. Lawv nqa tawm copycat imitation ntawm lub hwj huam mov Circuit Court, thiab lawv tsis to taub lub hauv paus ntsiab lus ntawm kev ua hauj lwm. Cov tshuab thiab cov khoom siv coj los ua ke muaj qee qhov tsis xws luag: ua ntej, qhov zoo ntawm cov khoom siv raw yuav tsis tuaj yeem lav, thiab qhov thib ob, cov thev naus laus zis tseem ceeb ntawm cov txheej txheem ntau lawm tsis tau ua tiav. Lub zog tso zis ntawm cov tshuab thiab cov cuab yeej siv feem ntau tsis ruaj khov thiab cov txiaj ntsig tau qis. Qee lub sij hawm cov tshuab thiab cov cuab yeej raug puas ntsoog, xws li ultrasonic transducer tso zis hluav taws xob transformer, thiab qhov tseem ceeb ntawm cov khoom siv sib nqus siv tsis tuaj yeem ntsuas qhov tseeb, xws li sib nqus saturation flux ceev, sib nqus induction siv, thiab lwm yam. Cov txheej txheem coil inductance yog qhov nyuaj heev , thiab tsev neeg hom kev cob qhia me me no tsis tuaj yeem lav tau. Yog li ntawd, nws yog qhov zoo dua los nkag siab txog cov lag luam qhov xwm txheej ua ntej yuav khoom ultrasound. Koj tsis tas yuav dig muag ua raws li cov neeg ua haujlwm muag khoom khav theeb, thiab koj tsis xav tau tus nqi xwb. Tsuas yog nyob rau hauv txoj kev no koj tuaj yeem txo qhov teeb meem.
3. Lub tswv yim tsis raug ntawm lub zog ultrasonic
Qhov loj ntawm ultrasonic tso zis hwj chim yog txiav txim los ntawm txoj kab uas hla thiab thickness ntawm piezoelectric ceramic, cov khoom, tsim qauv thiab ua technology. Lub ultrasonic transducer yog zoo li tus, thiab lub zog siab tshaj plaws kuj zoo li tus. Xav txog qhov loj ntawm cov zis hluav taws xob yog qhov nyuaj tag nrho. Nws tsis yog tias qhov loj dua lub ultrasonic transducer yog, ntau lub hwj chim raj siv nyob rau hauv lub hwj chim Circuit Court, lub zog tso zis ntau dua. Nws yog ib qho tsim nyog yuav tsum tau siv lub ntsuas ntsuas qhov tob tob kom ntsuas nws qhov amplitude, vim tias feem ntau cov neeg siv tsis paub txog kev paub txog ultrasonic, ua ke nrog cov neeg muag khoom tsis txaus ntseeg, muab cov neeg siv khoom nkag siab tsis raug ntawm kev siv hluav taws xob ntau npaum li cas tsis cuam tshuam. qhov loj ntawm qhov tso zis ultrasonic zog, xws li qis longitudinal zog, Txawm li cas los xij, lub zog loj siv thiab ntws tsuas yog qhia tias kev ua haujlwm ntawm cov tshuab thiab cov khoom siv tsawg, thiab tsis muaj lub zog loj.
