Dab tsi yog lub teeb liab taw qhia ntawm lub tshuab hluav taws xob ultrasonic?
Cov tshuab hluav taws xob ultrasonic tsim hluav taws xob cov cim ntawm qee zaus. Cov paib no tuaj yeem ua rau sine cov teeb liab lossis lub teeb liab mem tes. Qhov zaus tshwj xeeb no yog ntau zaus ntawm ultrasonic transducer. Feem ntau, qhov ntsuas zaus siv hauv ultrasonic cov khoom siv yog 25KHz, 28KHz, 35KHz, 40KHz; 1OOKHz, zaus ntau tshaj 100KHZ tsis tau siv dav, tab sis nrog kev siv thev naus laus zis txuas ntxiv, Kuv ntseeg tias kev siv nws yuav maj mam nthuav dav. Lub tshuab hluav taws xob ua tiav ultrasonic kuj yuav tsum muaj qhov txuas rov qab, uas feem ntau muab cov lus taw qhia tawm tswv yim hauv ob qho:
Thawj qhov yog los muab lub phiaj xwm hluav taws xob tsim tawm, peb paub thaum twg qhov voltage ntawm ultrasonic generator hloov. Cov zis tawm ntawm lub zog ultrasonic mov kuj yuav hloov pauv. Nyob rau lub sijhawm no, nws tau xav txog nyob hauv ultrasonic transducer uas cov neeg kho tshuab kev hloov pauv hloov, uas ua rau cov nyhuv tu ua haujlwm tsis ruaj khov. 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.
Qhov thib ob yog muab cov cim qhov nquag mus taug qab. Thaum lub ultrasonic transducer ua haujlwm ntawm qhov resonant zaus, nws cov kev ua haujlwm yog qhov siab tshaj, thiab kev ua haujlwm ruaj khov. Cov resonant zaus ntawm ultrasonic transducer yuav hloov vim kev sib dhos vim li cas thiab kev ua haujlwm kev laus. Yog lawm, ntau zaus ntawm qhov kev hloov pauv no tsuas yog txav, tsis yog hloov pauv. Muaj ntau qhov loj, qhov teeb meem tsawg zaus taug kev tuaj yeem tswj tau lub teeb liab ultrasonic lub zog, kom qhov zaus ntawm cov teeb liab ultrasonic zog tau tuaj yeem ua raws cov resonant zaus kis ntawm ultrasonic transducer nyob rau hauv qee yam Cia lub zog ultrasonic ua haujlwm rau hauv lub xeev zoo tshaj.
Lub tshuab hluav taws xob ultrasonic tau muab faib ua hom kev rov ua tus kheej muaj lub zog hluav taws xob thiab lwm yam kev tuaj yeem hom fais fab mov raws li tus qauv. Circuit Court tus kheej zoo siab tsis muaj qhov taw qhia, tab sis sib xyaw cov oscillation, lub zog ua kom muaj zog, tso zis hluav taws xob thiab hloov pauv mus rau hauv tag nrho los ua lub voj kev kaw. Lub voj raws li qhov ua kom dav thiab ntu cov lus tawm tswv yim los ua cov oscillator nrog lub zog ua kom pom tseeb. Thiab nws resonates ntawm cov tshuab resonance zaus ntawm lub transducer. Feem ntau siv hauv cov khoom me me nrog rau tus lej tsawg ntawm ultrasonic transducers; tab sis rau coob leej ntawm ultrasonic transducers, nws tsis tuaj yeem ua qhov ua tiav kom ua tiav cov nyhuv resonance. Yog li ntawd, feem ntau ntawm cov tshuab hluav taws xob ntau ntawm cov khoom siv ultrasonic tu chaw siv lwm txoj hauv kev zoo. Lub tshuab hluav taws xob ntawm lub tshuab ultrasonic welding feem ntau siv lub tshuab hluav taws xob ultrasonic tus kheej.
