Cas lub ultrasonic cutter ua hauj lwm?
Lub suab yog lub zog uas kis los ntawm nruab nrab, xws li cua, dej, thiab hlau.
Ultrasonic tsis yog ib qho "inaudible sound," qhov uas feem ntau tshaj 20 kHz. A 20-kHz zaus txhais tau hais tias ib qho chaw nruab nrab vibrates 20,000 zaug ib ob.
Ultrasonic cutter vibrates nws cov hniav nrog ib amplitude ntawm 10 - 70 μm nyob rau hauv lub longitudinal kev taw qhia. Qhov kev co yog qhov me me, nws tsis tuaj yeem pom. Qhov kev txav rov qab ua dua 20,000 - 40,000 zaug ib ob (20 - 40 kHz). Vim tias qhov no txav, ultrasonic cutter tau yooj yim hlais resin, roj hmab, nonwoven ntaub, zaj duab xis, cov khoom sib sau ua ke uas muaj ntau yam khoom muaj nuj nqis, thiab zaub mov.
Ultrasonic cutter yog tsim los ntawm ib tug "transducer" uas ua kom muaj kev sib tw thiab ib qho "oscillator" uas ua rau lub transducer. Lub tshuab piezoelectric yog siv rau qhov kev hloov. Thaum voltage yog hos, lub piezoelectric keeb displaces lub transducer los ntawm ob peb micrometers. Ib ntus ua ntaub ntawv thov qhov voltage generates kev co. Ib qho khoom muaj nws qhov tshwj xeeb zaus, uas yog qhov khoom siv ruaj khov thiab yooj yim rau co. Los ntawm ntxiv ib qho quab yuam sab nraud uas sib sau mus rau qhov tshwj xeeb zaus, quab yuam me me muaj peev xwm tau txais kev vibration loj. Qhov tshwm sim no yog hu ua resonance. Hauv cov phom ultrasonic, lub piezoelectric keeb generates lub zog uas resonates tag nrho lub cev, ntawm qhov transducer rau lub hau hniav, ua kom muaj kev vibration loj ntawm qhov taub. Lub oscillator periodically ua rau muaj qhov voltage rau resonate thiab tsav cov transducer. Siv ib qho tivthaiv ntawm lub tshuab raj ultrasonic hu ua lub horn rau sau lub cheeb tsam ntawm qhov cross-sectional, los ntawm piezoelectric lub caij mus rau lub hau hniav, tuaj yeem tau txais kev vibration loj dua.
