Daim Ntawv Thov Ntsiab Lus ntawm Ultrasonic Hauv Yas Vuam

1. Daim ntawv thov txoj ntsiab cai ntawm ultrasonic hauv yas vuam:

Kev siv ultrasonic tsis siv hauv kev ua cov yas, ntau qhov kev ua haujlwm tam sim no yog 15KHZ, 18KHZ, 20KHZ, 40KHZ. Lub hauv paus ntsiab lus yog siv cov khoom siv siab kawg ntawm kev ua haujlwm ntev nthwv dej kom xa cov nplaim kis mus rau qhov sib txawv ntawm cov yas. Nyob rau hauv qhov xwm txheej ntawm lub siab, cov roj molecules ntawm ob feem yas lossis lwm qhov chaw sib chwv nrog ib feem ntawm yas sib tsoo sib xyaw ua ke kom yaj, thiaj li siv tau cov yas sib txuas. Cov hom phiaj ua.

2, muaj pes tsawg leeg ntawm lub tshuab nqus ultrasonic

Lub tshuab nqus hlau ultrasonic feem ntau yog ua tiav ntawm cov khoom hauv qab no: lub tshuab hluav taws xob, pneumatic feem, qhov tswj hwm kev tswj hwm, thiab ntu hloov pauv.

Kev ua haujlwm tseem ceeb ntawm lub tshuab hluav taws xob yog hloov cov khoom siv hluav taws xob ntawm lub zog hluav taws xob 50HZ mus rau qhov loj-zaus (piv txwv li 20KHZ) high-voltage hluav taws xob hluav taws xob los ntawm kev siv hluav taws xob hluav taws xob.

Lub luag haujlwm tseem ceeb ntawm kev nqus dej yog ua kom tiav cov kev ua haujlwm siab, siab thiab lwm yam ua kom lub siab ua tiav thaum ua tiav.

Qhov kev tswj hwm txoj haujlwm tswj lub haujlwm ntawm tag nrho lub tshuab kom ua tiav cov txiaj ntsig kev ua tiav.

Lub tshuab hloov pauv yog siv los hloov cov hluav taws xob high-voltage hluav taws xob hluav taws xob tsim tawm los ntawm lub tshuab hluav taws xob mus rau kev siv tshuab kev co, uas yog kis, ua kom nrov dua, thiab nce mus txog qhov chaw machined.

3. Cov transducer muaj peb ntu: Hloov pauv hloov (HLOOV); Amplifier (tseem hu ua tus pas nrig thib ob, tshuab raj, BOOSTER); Weld taub hau (tseem hu ua vuam, HORN lossis SONTRODE).

1 Transducer (TRANSDUCER): Kev ua haujlwm ntawm kev hloov pauv yog hloov mus rau hluav taws xob cov cim rau hauv kev co lub tshuab kev co. Muaj ob qhov teebmeem ntawm lub cev uas tuaj yeem siv los hloov hluav taws xob hluav taws xob mus rau cov teeb liab kev co lub tshuab. A: Cov nyhuv Magnetostrictive. B: Qhov cuam tshuam ntawm cov nyhuv piezoelectric. Cov nyhuv magnetostrictive yog siv ntau thaum ntxov hauv ultrasonic daim ntaub ntawv. Qhov zoo dua yog lub peev xwm fais fab tuaj yeem ua loj; qhov tsis zoo yog tias qhov hloov dua siab tshiab ua haujlwm tsawg, kev tsim khoom yog qhov nyuaj, thiab nws yog qhov nyuaj rau huab hwm coj-kev tsim khoom lag luam. Txij li qhov tsim muaj ntawm Langevin piezoelectric ceramic transducer, daim ntawv thov ntawm piezoelectric lub zog ua haujlwm tau txais tau dav siv. Piezoelectric ceramic transducers muaj qhov zoo ntawm qhov hloov dua siab tshiab ntau lawm, tsim kom loj, thiab lwm yam zoo li qhov tsis zoo yog lub zog tsim hluav taws xob yog me me. Tshuab ultrasonic uas twb muaj lawm feem ntau siv cov piezoelectric ceramic transducers. Piezoelectric ceramic transducers yog tsim los ntawm sandwiching piezoelectric ceramics nrog ob daim hlau pem hauv ntej thiab sab nraub qaum cov khoom thauj thiab txuas nruj lawv los ntawm txoj kev screws. Lub amplitude ntawm cov zis hloov pauv ib txwm yog li ntawm 10 μm.

2 Vuam lub taub hau (HORN): Txoj haujlwm ntawm lub taub hau vuam yog ua rau qee qhov yas, raws li cov duab thiab ua ntau yam ntawm cov feem ntawm cov yas.

Cov transducers, tshuab raj, thiab tshuab raj tau tsim los ua ib nrab nthwv dej ntawm lub zaus ultrasonic thaum ua haujlwm, yog li lawv qhov loj thiab cov duab yog tsim tshwj xeeb; cov kev hloov pauv yuav ua rau muaj kev hloov pauv hloov mus los thiab qhov cuam tshuam. Kev tshaj lij kev lag luam. Lub sijhawm ua haujlwm txawv nyob ntawm cov ntaub ntawv siv. Cov ntaub ntawv uas haum rau ultrasonic transducers, tshuab raj thiab lub taub hau vuam yog: titanium alloy, aluminium alloy, alloy hlau, thiab cov zoo li. Txij li lub ultrasonic vuag tau txav tas li ntawm lub siab ntawm kwv yees li 20 kHz, cov khoom yuav tsum yog siab heev thiab tsis pheej yig rau cov ntaub ntawv zoo tib yam.
