1. Piezoelectric Ceramic Transformer
Piezoelectric ceramic transformers siv cov nyhuv piezoelectric ntawm lub cev piezoelectric tom qab polarization kom ua tiav cov zis hluav taws xob. Lub tswv yim ib feem yog tsav los ntawm ib tug sinusoidal voltage teeb liab, thiab nws vibrates los ntawm inverse piezoelectric nyhuv. Lub vibration nthwv dej yog mechanically txuas mus rau qhov tso zis ib feem los ntawm cov tswv yim thiab tso zis qhov chaw, thiab cov zis ib feem generates tsub nqi los ntawm lub zoo piezoelectric nyhuv kom paub txog lub zog hluav taws xob ntawm lub piezoelectric lub cev. - Ob qhov kev hloov pauv ntawm lub zog siv hluav taws xob-hluav taws xob kom tau txais qhov tso zis ntau tshaj plaws ntawm qhov resonant zaus ntawm piezoelectric transformer. Piv nrog electromagnetic hloov pauv, qhov no muaj qhov hnyav, tsis ntshai kev cuam tshuam, kev kub ntxhov ntau, thiab cov qauv hluav taws xob, yooj yim, ua kom yooj yim, yooj yim rau huab hwm coj ntau lawm, nyob rau hauv tej qhov chaw ua zoo tagnrho hloov Cheebtsam rau electromagnetic transformers thiab lwm yam zoo. Xws li transformers yog siv nyob rau hauv kev hloov pauv hloov pauv, phau computers, neon teeb tsav tsheb, thiab lwm yam.
2. Ultrasonic Tsav
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.
3. Ultrasonic ntxuav
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. Raws li qhov zaus ntawm ultrasonic transducer nce, Langevin oscillators, longitudinal oscillators, thickness oscillators, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm miniaturization, kuj muaj radial kev co thiab dabtsi yog khoov kev co ntawm lub wafer vibrator. Ultrasonic tu yog siv ntau hauv kev 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.
4. 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 siv yas, txo lub sijhawm ua haujlwm, txhim kho kev tsim khoom, thiab muaj cov yam ntxwv ntawm kev lag luam, ceev thiab kev ntseeg siab.
5. Ultrasonic ua
Thaum cov nplua abrasive ntxiv rau lub workpiece nrog ib tug tej yam zoo li qub siab nrog rau lub ultrasonic machining cuab tam, zoo 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, thaum ntxiv ultrasonic transducer kev co rau cov cuab yeej txiav zoo tib yam, nws tuaj yeem ua lub luag haujlwm hauv kev txhim kho qhov tseeb thiab kev ua haujlwm zoo.
6. Ultrasonic 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 thiab emulsified thiab ces tawm ntawm lub cev, thiaj li mus cuag lub hom phiaj ntawm kev poob phaus thiab shaping. Qhov no yog lub tshuab tshiab tsim thoob ntiaj teb hauv xyoo 1990s.
7. Ultrasonic yug me nyuam
Tsim nyog zaus thiab siv ntawm ultrasonic irradiation ntawm cov nroj tsuag cov noob tuaj yeem txhim kho cov germination tus nqi ntawm cov noob, txo tus nqi ntawm mildew thiab 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.
