Daim Ntawv Thov ntawm Ultrasonic Transducer
Ultrasonic transducers yog siv dav. Raws li daim ntawv thov kev lag luam, lawv tau muab faib ua kev lag luam, kev ua liaj ua teb, tsheb thauj mus los, lub neej, kev kho mob thiab kev ua tub rog. Raws li lub zog ua haujlwm tau hais, nws muab faib ua ultrasonic, kev tu ultrasonic, kuaj ultrasonic, nrhiav kom pom, tshuaj xyuas, telemetry, chaw taws teeb tswj, thiab lwm yam; raws li kev ua haujlwm ntawm ib puag ncig, nws muab faib ua kua, roj av, roj ntsha lub cev, thiab lwm yam.; raws li tus xwm, nws muab faib ua fais fab tuag ultrasonic, kuaj pom ultrasonic, ntsuas ultrasonic, thiab lwm yam.
Piezoelectric ceramic transformer
Lub piezoelectric ceramic transformer siv cov nyhuv piezoelectric ntawm polarized piezoelectric lub cev kom ua tiav cov zis hluav taws xob. Cov tswv yim qhov yog tsav los ntawm sinusoidal voltage teeb liab thiab vibrates los ntawm qhov ua tsis tau zoo rau piezoelectric effect. Lub tshuab kev co hluav taws xob sib xyaw ua ke nrog kev tsim tawm los ntawm cov tswv yim thiab cov khoom tso tawm, thiab qhov tso tawm hluav taws xob tso hluav taws xob los ntawm qhov zoo piezoelectric cov nyhuv kom paub lub zog hluav taws xob ntawm lub piezoelectric lub cev. -Mechanical lub zog-ob qho kev hloov pauv ntawm hluav taws xob lub zog kom tau txais cov hluav taws xob ntau tshaj plaws ntawm lub siab ntawm cov hluav taws xob piezoelectric transformer. Piv nrog rau lub tshuab hluav taws xob hloov pauv hloov, qhov no muaj qhov zoo ntawm qhov loj me, lub teeb nyhav, lub zog loj, kev ua haujlwm siab, kev tiv thaiv kev tawg, qhov kub tsis kam, tsis muaj kev ntshai ntawm kev kub hnyiab, tsis muaj hluav taws xob cuam tshuam thiab hluav taws xob, thiab cov qauv yooj yim, yooj yim ntau lawm, thiab yooj yim huab hwm coj ntau lawm. Hauv qee thaj chaw, nws tau dhau los ua qhov zoo tshaj plaws rau kev hloov hluav taws xob. Hom transformer no siv nyob rau hauv kev hloov mus rau kev hloov pauv, phau ntawv sau lub computer, neon teeb tsav tsheb, thiab lwm yam
Ultrasonic lub cev muaj zog
Ultrasonic motors siv cov stator ua qhov hloov pauv, siv cov thim rov qab piezoelectric nyhuv ntawm cov piezoelectric siv lead ua kom lub cev muaj zog stator co ntawm lub zaus ultrasonic, thiab tom qab ntawd tso siab rau qhov kev sib txhuam ntawm stator thiab lub rotor hloov lub zog thiab tsav lub rotor tig Cov. Kev loj me me, lub cev loj loj, kev daws teeb meem siab, cov qauv yooj yim, kev tsav tsheb ncaj qha, tsis muaj lub tshuab nres, tsis muaj cov kabmob cav, cov kev zoo no tau txais txiaj ntsig rau qhov miniaturization ntawm lub cuab yeej. Nws yog dav siv hauv kev kho qhov muag ntawm cov twj paj nruag, lasers, semiconductor microelectronics cov txheej txheem, cov tshuab ua kom zoo nkauj thiab cov twj paj nruag, neeg hlau, tshuaj thiab kev siv roj ntsha.
Tu ultrasonic
Lub tshuab yog siv cov teebmeem ntawm lub cev xws li cavitation, hluav taws xob lub zog, thiab lub suab ntws thaum lub suab ultrasonic tsis sib haum xeeb hauv cov kua ua kom huv rau tev tawm ntawm cov tshuab uas tsim los ntawm cov av ntawm cov khoom ntxuav, thiab tib lub sijhawm, nws tuaj yeem txhawb cov tshuaj lom neeg. cov tshuaj tiv thaiv ntawm cov kua ntxuav thiab cov av kom ua tiav Lub hom phiaj ntawm cov khoom ntxuav. Tus nquag siv yuav raug xaiv los ntawm 10 txog 500 kHz raws li qhov loj me thiab lub hom phiaj ntawm cov khoom siv ntxuav, feem ntau 20 mus rau 50 kHz. Raws li qhov zaus nce ntxiv, Langevin vibrators, lub neej ntev kev co, cov tuab tuab vibrators, thiab lwm yam tuaj yeem siv. Hais txog kev ua tej yam me me, kuj tseem muaj kev ua kom dhau radial thiab flexural siv disc vibrators. Nws tau siv dav hauv ntau yam lag luam, kev ua liaj ua teb, khoom siv hauv tsev, khoom siv hluav taws xob, tsheb, roj hmab, luam ntawv, dav hlau, khoom noj khoom haus, tsev kho mob, thiab kev tshawb fawb kho mob.
Ultrasonic vuam
Muaj ob hom ultrasonic vuam: ultrasonic hlau vuam thiab ultrasonic yas vuam. Ntawm lawv, ultrasonic yas vuam tshuab tau siv dav. Nws siv ultrasonic kev co kev tsim tawm los ntawm lub tshuab hloov mus xa cov ultrasonic kev co lub zog mus rau thaj chaw welding los ntawm kev muab txuas rau sab saud. Vim tias qhov loj acoustic tsis kam ntawm qhov chaw vuam, uas yog, kev sib txuas ntawm ob qhov txuas, qhov kub hauv zos yuav tsim kom yaj cov yas, thiab kev ua haujlwm vuam yuav ua tiav nyob rau hauv qhov kev txiav txim ntawm kev sib cuag siab. Ultrasonic yas vuam tuaj yeem pab txhawb vuam ntawm qhov chaw uas tsis tuaj yeem txuas ua ke los ntawm lwm txoj hauv kev vuam. Tsis tas li ntawd, nws tseem txuag cov nqi tsim pwm rau cov khoom yas, ua lub sijhawm luv luv, txhim kho kev ua haujlwm ntau lawm, thiab kev lag luam yooj yim, ceev ceev, thiab ntseeg tau.
Ultrasonic machining
Cov khoom siv zoo abrasive tau thov rau qhov teeb meem ua haujlwm nrog qee qhov siab zoo li lub zog ua ke nrog cov twj, thiab cov duab zoo li lub cuab tam tuaj yeem ua. Lub sijhawm ua haujlwm, tus hloov khoom yuav tsum tsim kom muaj zog ntawm 15-40 microns ntawm qhov ntau zaus ntawm 15-40kHz. Cov cuab yeej ultrasonic ua rau cov abrasive nyob rau saum npoo ntawm workpiece txuas ntxiv cuam tshuam nrog kev cuam tshuam ntau qhov kev quab yuam, rhuav tshem ultrasonic tawg feem, thiab tawg cov khoom kom ua tiav lub hom phiaj ntawm kev tshem tawm cov khoom. Kev ua cov txheej txheem ultrasonic yog siv rau kev ua cov khoom tawg thiab tawv xws li gems, jade, marble, agate, thiab cemented carbide, nrog rau kev ua cov txheej txheem tshwj xeeb thiab lub qhov loj. Ntxiv rau, thaum kev vibration ntxiv rau cov cuab yeej txiav zoo tib yam, nws kuj tuaj yeem txhim kho qhov tseeb thiab ua haujlwm.
Ultrasound poob phaus
Siv cov nyhuv cavitation thiab micro-mechanical kev co, cov roj ntsha ntau dhau hauv tib neeg lub cev kev zom zaws, ua kom tawg thiab tawm kom ua tiav lub hom phiaj ntawm qhov hnyav thiab ua kom zoo dua. Nov yog ib qho txuj ci tshiab tsim tawm thaum xyoo 1990 thoob ntiaj teb. Zocchi los ntawm Ltalis siv ultrasonic degreasing rau lub txaj thawj zaug thiab muaj kev vam meej, teeb tsa ua ntej rau kev phais yas thiab kev zoo nkauj. Ultrasonic rog tshem tawm tshuab tau tsim sai heev tom tsev thiab txawv teb chaws.
Ultrasonic chaw ua taus zes
Kev cog qoob loo rau cov noob nrog qhov tsim nyog thiab siv zog ntawm cov ultrasonic kev tuaj yeem tuaj yeem nce tus nqi ntawm cov noob, txo tus nqi ntawm cov pwm, txhawb kev loj hlob ntawm cov noob, thiab nce qhov 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 ntawm 2 txog 3 zaug.
Ntshav Tes Ntshav Ntshav
Siv lub siab ntawm cov tau txais cov hlab ntsha, thaum airbag compresses cov hlab ntshav, vim tias qhov kev thov siab yog siab dua vasodilation siab, cov hlab ntsha tsis tuaj yeem hnov tau; thiab thaum twg airbag yog maj deflated, lub siab ntawm cov hlab ntshav yuav nqis mus rau ib qho nqi. Thaum lub siab ntawm ob mus txog qhov sib txig sib luag, lub siab ntawm cov hlab ntsha tuaj yeem xav tau nyob rau lub sijhawm no. No lub siab yog systolic siab rau ntawm lub plawv. Qhov ntsuas lub cim tau xa los ntawm lub suab nrov kom muab cov ntshav siab tus nqi. Vim tias cov xov hluav taws xob sphygmomanometer tshem tawm cov stethoscope, kev siv zog ntawm cov neeg ua haujlwm kho mob yuav raug txo kom tsawg.
