Lub tshuab hluav taws xob ultrasonic ua tau dab tsi? Dab tsi yog cov tshuab hluav taws xob ultrasonic ...
(1) Ultrasonic lub tshuab hluav taws xob, tseem hu ua ultrasonic tsav fais fab mov, lub thawv hluav taws xob, maub los, yog qhov tseem ceeb ntawm lub zog loj ultrasonic system:
(2) Qhov high-frequency hloov ua lub teeb liab tam sim no sib luag los ntawm lub tshuab hluav taws xob ultrasonic thiab ultrasonic lub tshuab hluav taws xob yog siv los tsav lub ultrasonic transducer ua haujlwm.
(3) cov khoom siv hluav taws xob muaj zog siab dav dav txais yuav daim ntawv Circuit Court ntawm kev hloov cov khoom siv fais fab.
(4) Cov khoom siv fais fab ultrasonic tau muab faib ua cov khoom siv fais fab zoo siab rau tus kheej thiab lwm cov khoom siv fais fab zoo siab. Cov khoom siv fais fab tus kheej zoo siab hu ua ultrasonic analog cov khoom siv fais fab, thiab cov khoom siv fais fab tshwj xeeb sab nraud hu ua ultrasonic generators.
(5) Lub tshuab hluav taws xob ultrasonic siv cov kev tsim hluav taws xob oscillation Circuit Court sib cais, uas ua kom cov zis hluav taws xob tso tawm ntau dua 10% piv nrog tus kheej oscillation Circuit Court qauv.
(6) Daim ntawv ntawm ultrasonic amplifying Circuit Court adopts linear amplifying Circuit Court thiab lub zog hloov hluav taws xob tsis ua haujlwm Circuit Court.
2. qhov zoo ntawm cov hluav taws xob hloov fais fab Circuit Court: muaj qhov hloov siab hloov dua siab tshiab, yog li lub siab-lub zog fais fab ultrasonic fais fab pom zoo daim ntawv no.
(1) Qhov zoo ntawm cov hluav taws xob ua kab sib tshooj: kev sib txuam ntawm cov hluav taws xob tsis yog nruj me ntsis, thiab qhov ua haujlwm zaus raug tso cai hloov pauv tsis tu ncua thiab nrawm.
(2) Lub tshuab hluav taws xob ultrasonic tsim hluav taws xob cov cim ntawm qee zaus. Lub teeb liab ntawm lub tshuab hluav taws xob ultrasonic tuaj yeem yog qhov teeb meem sinusoidal lossis cov teeb liab mem tes. Qhov zaus tshwj xeeb no yog zaus ntawm qhov hloov ua haujlwm.
(3) Ultrasonic zaus ntau siv los ntawm cov khoom siv ultrasonic yog 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz, 80KHz, 100KHz lossis siab dua cov zaus uas tsis tau siv ntau.
3. Tawm fais fab tuag
Thaum qhov voltage ntawm lub tshuab hluav taws xob ultrasonic tau hloov, qhov tsim tawm ntawm lub tshuab hluav taws xob kuj hloov, uas yuav ua rau lub tshuab kev co ntawm lub tshuab hluav taws xob ultrasonic tsis ruaj khov thiab ua rau kev ua haujlwm tsis zoo.
Yog li ntawd, nws yog qhov tsim nyog los tswj lub zog tso zis tawm, thiab kho lub zog loj ntxiv raws li lub zog cov lus taw qhia lub zog kom ua kom lub zog amplification ruaj khov.
4. Kev xa mus ntau zaus
Thaum lub tshuab hloov ua haujlwm ntawm qhov zaus, nws muaj qhov ua haujlwm siab thiab ua haujlwm ruaj khov.
Lub resonant zaus kis ntawm qhov transducer yuav hloov vim kev sib dhos thiab kev ua haujlwm kev laus. Yog tias qhov hloov pauv zaus tsuas yog drifts thiab tsis hloov ntau, lub teeb liab mus txog kev tswj xyuas tuaj yeem tswj lub teeb liab lub tshuab hluav taws xob, kom cov zaus ntawm lub teeb liab hluav taws xob tuaj yeem ua raws li qhov hloov siab zaus ntawm lub transducer nyob rau hauv qee qhov, thiab lub tshuab hluav taws xob tuaj yeem ua haujlwm nyob rau hauv zoo dua xeev.
