Daim ntawv thov teb ntawm Ultrasonic Transducers

Ultrasonic transducers tau siv dav, thiab lawv tau muab faib rau hauv kev lag luam, kev ua liaj ua teb, kev thauj mus los, lub neej, kev kho mob, thiab tub rog raws li daim ntawv thov kev lag luam. Raws li kev paub txog kev ua haujlwm, nws tau muab faib ua ultrasonic ua, ntxuav ultrasonic, kuaj ultrasonic, kuaj xyuas, tshuaj xyuas, telemetry, chaw taws teeb tswj, thiab lwm yam .; raws li qhov chaw ua haujlwm, nws muab faib ua kua, roj, lub cev muaj sia, thiab lwm yam .; Raws li qhov xwm txheej, nws tau muab faib ua lub zog ultrasonic, nrhiav kom tau ultrasonic, ultrasonic imaging, thiab lwm yam.

Ultrasonic lub cev muaj zog

Lub tshuab hluav taws xob ultrasonic siv lub stator ua lub tshuab hluav taws xob, siv cov nyhuv piezoelectric inverse ntawm piezoelectric siv lead ua kom lub cev muaj zog stator vibrate ntawm ultrasonic zaus, thiab tom qab ntawd xa lub zog los ntawm kev sib txhuam ntawm stator thiab lub rotor tsav lub rotor tig. Ultrasonic motors muaj me me, loj torque, siab daws teeb meem, qauv yooj yim, ncaj qha tsav, tsis muaj braking mechanism, thiab tsis muaj bearing mechanism. Cov txiaj ntsig zoo no muaj txiaj ntsig zoo rau lub tshuab ua haujlwm me me. Ultrasonic motors yog dav siv nyob rau hauv optical instruments, lasers, semiconductor microelectronics, precision machinery thiab instruments, neeg hlau, tshuaj, thiab bioengineering.

Ultrasonic tu

Lub tshuab ntawm ultrasonic tu yog siv lub cev los ntawm cavitation, hluav taws xob siab, suab nrov, thiab lwm yam thaum lub ultrasonic yoj propagates nyob rau hauv cov tshuaj ntxuav, mechanically tev tawm cov av ntawm qhov chaw tu, thiab tib lub sijhawm, nws tuaj yeem txhawb kev tsim tshuaj lom neeg ntawm cov tshuaj ntxuav thiab cov av. cov tshuaj tiv thaiv kom ua tiav lub hom phiaj ntawm kev ntxuav cov khoom. Qhov zaus siv los ntawm lub tshuab ntxuav ultrasonic tuaj yeem xaiv los ntawm 10 mus rau 500 kHz raws li qhov loj thiab lub hom phiaj ntawm cov khoom tu, feem ntau 20 txog 50 kHz. Nrog rau qhov nce ntawm ultrasonic transducer zaus, Langevin oscillator, longitudinal oscillator, thickness oscillator, thiab lwm yam yuav siv tau. Nyob rau hauv cov nqe lus ntawm miniaturization, kuj muaj radial vibrations thiab dabtsi yog khoov vibrations ntawm wafer vibrator. Ultrasonic tu yog siv ntau hauv kev lag luam, suav nrog kev ua liaj ua teb, khoom siv hauv tsev, khoom siv hluav taws xob, tsheb, roj hmab, luam ntawv, dav hlau, zaub mov, tsev kho mob, thiab kev tshawb fawb txog kev kho mob.

Ultrasonic vuam

Ultrasonic vuam tuaj yeem muab faib ua ob pawg: ultrasonic hlau vuam thiab ultrasonic yas vuam. Ntawm lawv, ultrasonic yas vuam tshuab tau dav siv. Nws siv lub ultrasonic vibration generated los ntawm lub transducer mus kis lub zog ultrasonic kev co mus rau lub vuam cheeb tsam los ntawm lub qaum weldment. Vim qhov loj acoustic tsis kam nyob rau hauv lub vuam cheeb tsam, uas yog, lub hlws ris ntawm ob welds, lub zos kub kub yuav generated rau yaj cov yas, thiab welding ua hauj lwm yuav ua tiav nyob rau hauv kev txiav txim ntawm kev sib cuag siab. Ultrasonic yas vuam tuaj yeem pab txhawb kev vuam ntawm qhov chaw uas tsis tuaj yeem welded los ntawm lwm txoj kev vuam. Tsis tas li ntawd, nws tseem txuag tau tus nqi pwm kim ntawm cov khoom yas, txo lub sijhawm ua haujlwm, txhim kho kev tsim khoom, thiab muaj cov yam ntxwv ntawm kev lag luam, ceev thiab kev ntseeg tau.

Ultrasonic machining

Cov zoo abrasive yog siv rau lub workpiece nrog ib tug tej yam zoo li qub siab ua ke nrog lub ultrasonic machining cuab tam, thiab tib yam li lub cuab tam yuav machined. Thaum lub sij hawm ua, lub transducer yuav tsum tau tsim ib qho amplitude ntawm 15 mus rau 40 microns ntawm ib zaus ntawm 15 mus rau 40 kHz. Lub cuab yeej ultrasonic ua rau cov abrasive ntawm qhov chaw ntawm lub workpiece tsis tu ncua cuam tshuam nrog kev cuam tshuam loj heev, rhuav tshem cov hluav taws xob ultrasonic, thiab rhuav tshem cov khoom kom ua tiav lub hom phiaj ntawm kev tshem tawm cov khoom. Kev ua ultrasonic feem ntau yog siv rau hauv kev ua cov khoom siv tawv tawv xws li pob zeb, jade, marble, agate, thiab cemented carbide, nrog rau kev ua cov qhov tshwj xeeb zoo li lub qhov thiab nplua thiab tob qhov. Tsis tas li ntawd, ntxiv ultrasonic transducers rau cov cuab yeej txiav zoo tib yam kuj tuaj yeem ua lub luag haujlwm hauv kev txhim kho qhov tseeb thiab kev ua haujlwm zoo.

Ultrasound rau poob phaus

Siv cov nyhuv cavitation thiab micro-mechanical vibration ntawm lub ultrasonic transducer, cov roj ntsha ntau dhau nyob rau hauv tib neeg epidermis yog tawg, emulsified, thiab tawm ntawm lub cev, thiaj li ua tiav lub hom phiaj ntawm kev poob phaus thiab shaping. Qhov no yog lub tshuab tshiab tsim thoob ntiaj teb hauv xyoo 1990s. ltalis Zocchi siv ultrasonic tshem tawm cov rog thawj zaug hauv txaj, thiab ua tiav kev ua tiav, tsim kom muaj kev ua ntej rau kev phais yas thiab kev zoo nkauj. Ultrasonic roj tshem tawm tshuab tau tsim sai heev hauv tsev thiab txawv teb chaws.

Ultrasonic yug me nyuam

Tsim nyog zaus thiab kev siv ntawm ultrasonic irradiation ntawm cov noob cog tuaj yeem txhim kho qhov kev loj hlob ntawm cov noob, txo tus nqi ntawm pwm rot, txhawb kev loj hlob ntawm cov noob, thiab txhim kho kev loj hlob ntawm cov nroj tsuag. Raws li cov ntaub ntawv, ultrasound tuaj yeem nce qhov kev loj hlob ntawm qee cov noob cog los ntawm 2 mus rau 3 zaug.

Ntshav Siab Monitor

Ultrasonic transducer yog siv los tau txais lub siab ntawm cov hlab ntsha. Thaum lub zais pa yog compressed thiab nias tawm tsam cov hlab ntsha, lub ultrasonic transducer tsis tuaj yeem hnov ​​​​lub siab ntawm cov hlab ntsha vim hais tias qhov kev thov siab siab tshaj qhov vasodilation siab. Thaum lub siab ntawm cov hlab ntsha txo mus rau ib qho nqi, qhov siab ntawm ob mus txog qhov sib npaug. Thaum lub sij hawm no, lub ultrasonic transducer tuaj yeem hnov ​​​​lub siab ntawm cov hlab ntsha, uas yog lub siab systolic ntawm lub plawv. ntshav siab tus nqi. Lub tshuab hluav taws xob sphygmomanometer tuaj yeem txo qhov kev siv zog ntawm cov neeg ua haujlwm kho mob vim qhov kev tshem tawm ntawm lub stethoscope.

Telemetry chaw taws teeb tswj

Hauv cov tshuaj lom neeg, xov tooj cua, thiab lwm qhov chaw hnyav, tib neeg tsis tuaj yeem ua haujlwm ze rau nws, thiab yuav tsum tau tswj xyuas qhov chaw deb; hluav taws xob hloov xws li TV, kiv cua, thiab teeb yuav tsum muaj cov chaw taws teeb tswj, thiab ultrasonic transducers tuaj yeem ntsia tau los xa cov nthwv dej ultrasonic los ntawm qhov chaw deb. Lub txais transducer ntawm qhov kev tswj hwm hloov cov teeb liab acoustic rau hauv lub teeb liab hluav taws xob los ua qhov hloov pauv.

Kev saib xyuas tsheb

Hauv kev tsheb niaj hnub no, nws yog ib qho tsim nyog yuav tsum tau saib xyuas kev hla thiab suav cov tsheb txhawm rau txhawm rau txhawm rau ua haujlwm ntawm cov tsheb. Piv txwv li, lub chaw saib xyuas kev khiav tsheb nruab ib lub ultrasonic transducer thiab nws cov cuab yeej pab rau ob qho tib si transceiver thiab kis tau tus mob. Thaum lub tsheb hla dhau, lub acoustic mem tes rov qab thiab cov naj npawb ntawm cov tsheb niaj hnub tuaj yeem tau los ntawm kev suav thiab sib sau. Ob lub hom phiaj transducer yog ntsia rau tom qab ntawm lub tsheb kom tiv thaiv kev sib tsoo rov qab. Txhim kho qhov tau txais piezoelectric ultrasonic transducer ntawm txoj kev tuaj yeem saib xyuas lub suab nrov.

Kev sib tw

Ib qho khoom siv Ultrasonic kuj tseem hu ua tus kav suab. Nws ntsuas lub sij hawm mem tes ib ntus los ntawm ob lub hom phiaj transducer. Lub suab ntsuas tuaj yeem ntsuas qhov deb li ntawm 10m, thiab qhov tseeb tuaj yeem ncav cuag ntau txhiab.

Kev kuaj pom cov pa paug thiab kuaj pom roj

Rau qhov system siab, ntawm qhov xau, lub suab nrov ntawm lub dav hlau yog tshwm sim los ntawm qhov sib txawv ntawm qhov siab ntawm sab hauv thiab sab nraud ntawm lub nkoj siab. Lub suab nrov spectrum no dav heev. Rau cov tshuab tsis muaj zog, ib qho ultrasonic tuaj yeem muab tso rau hauv lub kaw lus kaw thiab tau txais los ntawm sab nraud lub kaw lus kaw. Feem ntau, lub teeb liab amplitude ntsuas thaum tsis muaj qhov xau me me los yog tsis muaj, thiab lub teeb liab amplitude nyhav nce dheev ntawm qhov to. Gas flow detection kuj yog ib qho tseem ceeb hauv kev lag luam tshuaj. Muaj ntau yam amplifications rau kev khiav dej num, xws li rotameters thiab lwm yam. Tab sis lub ntsiab kom zoo dua ntawm kev siv lub ultrasonic transducer yog tias nws tsis cuam tshuam cov dej ntws.

Cov ntaub ntawv khaws tseg

Txhawm rau kom paub txog kev ua haujlwm xws li taug kev dawb hauv qhov chaw thiab paub txog cov khoom, cov neeg hlau ntse tsis tsuas yog yuav tsum siv ultrasonic transducers los ntsuas qhov deb thiab coj cov qhov muag tsis pom tab sis kuj yuav tsum paub txog cov duab. Yog li ntawd, me me ultrasonic transducer arrays yuav tsum tau ua kom tiav ntau lub zog, thiab qhov nam no yuav dhau los ua ib qho kev tshawb fawb tseem ceeb, nyiam ntau tus kws tshawb fawb los siv zog rau nws.
