Txheej txheem cej luam ntawm Ultrasonic Transducers
Lub ultrasonic transducer feem ntau yog tsim los ntawm peb qhov chaw: transducer, amplifier (tseem hu ua tus pas nrig thib ob, lub zog), vuam horn (tseem hu ua vuam pwm).
Transducer (TRANSDUCER): Lub luag haujlwm ntawm transducer yog hloov hluav taws xob teeb liab mus rau cov khoom siv hluav taws xob kev co. Muaj ob qhov teebmeem ntawm lub cev uas tuaj yeem siv los hloov cov teeb liab hluav taws xob rau hauv cov cim kev vibration. A: Magnetostrictive nyhuv, B: Inverse nyhuv ntawm piezoelectric nyhuv. Cov nyhuv magnetostrictive feem ntau yog siv rau hauv cov ntawv thov ultrasonic thaum ntxov, thiab nws qhov zoo yog tias nws muaj peev xwm loj zog; Txij li thaum lub invention ntawm Langevin piezoelectric ceramic transducer, daim ntawv thov ntawm inverse nyhuv ntawm piezoelectric nyhuv tau dav siv. Piezoelectric ceramic transducers muaj qhov zoo ntawm kev hloov pauv siab thiab tsim nyog rau ntau lawm, tab sis qhov tsis zoo yog tias lub zog muaj peev xwm tsim tau me me. Cov tshuab ultrasonic uas twb muaj lawm feem ntau siv piezoelectric ceramic transducers. Piezoelectric ceramic transducers yog tsim los ntawm sandwiching piezoelectric ceramics ntawm ob hlau pem hauv ntej thiab nram qab load blocks thiab nruj nreem txuas nrog screws. Feem ntau, cov zis amplitude ntawm lub transducer yog hais txog 10 μm.
Vuam lub taub hau (HORN): Lub luag haujlwm ntawm lub taub hau vuam yog ua kom cov yas tshwj xeeb thiab ua tau raws li qhov yuav tsum tau ua ntawm cov duab thiab kev ua haujlwm ntawm cov yas.
Cov transducers, booster, thiab vuam taub hau yog tag nrho cov tsim los ua ib nrab-yoj ntawm ultrasonic zaus lawv ua haujlwm, yog li lawv qhov loj thiab cov duab yuav tsum tau tsim tshwj xeeb. Txhua qhov kev hloov pauv tuaj yeem ua rau muaj kev hloov pauv ntawm zaus thiab kev ua haujlwm. Professionally ua. Dimensions txawv nyob ntawm seb cov khoom siv. Cov ntaub ntawv tsim nyog rau ultrasonic transducers, horns thiab vuam taub hau yog: titanium alloy, aluminium alloy, alloy steel, thiab lwm yam. Txij li thaum lub ultrasonic yoj vibrates tsis tu ncua ntawm ib tug high zaus ntawm txog 20kHz, qhov yuav tsum tau rau cov khoom yog siab heev, uas yuav tsis raug zam. los ntawm cov khoom siv zoo tib yam.
