Ultrasonic transducer yog lub zog hloov hluav taws xob uas hloov cov hluav taws xob hloov hluav taws xob rau hauv cov teeb liab acoustic lossis cov teeb liab acoustic rau hauv hluav taws xob teeb liab hauv qhov ntau zaus ultrasonic. Nws yog ib qho khoom siv tseem ceeb hauv cov khoom siv ultrasonic, yog li tsis muaj teeb meem txawm tias nws yog nyob rau hauv cov txheej txheem transduction los yog cov txheej txheem tsim thiab lwm tus neeg tau txais kev saib xyuas ntev.
Kev ua haujlwm tsis zoo ntawm ultrasonic transducers
Ultrasonic transducer yog lub zog hloov khoom siv, thiab nws cov lus piav qhia thiab kev ntsuas yuav tsum muaj ntau yam tsis muaj. Cov yam ntxwv tsis zoo ntawm ultrasonic transducer muaj xws li resonance zaus, zaus bandwidth, electromechanical coupling coefficient, electroacoustic efficiency, mechanical zoo yam, impedance yam ntxwv, zaus yam ntxwv, directivity, kis thiab tau txais rhiab heev, thiab lwm yam. Qhov kev ua tau zoo ntawm transducers rau cov hom phiaj sib txawv, yuav tsum tau transducers ultrasonic transducers. kom muaj zog tso zis loj thiab siab zog hloov dua siab tshiab efficiency; Txhawm rau tau txais ultrasonic transducers, yuav tsum muaj ntau zaus band thiab siab rhiab heev thiab kev daws teeb meem. Yog li ntawd, nyob rau hauv cov txheej txheem tsim tshwj xeeb ntawm lub transducer, qhov cuam tshuam tsis zoo ntawm lub transducer yuav tsum tau ua raws li cov ntawv thov tshwj xeeb tsim nyog.
Txoj kev tsom xam ntawm ultrasonic transducer
Ultrasonic transducers muaj xws li Circuit Court system, mechanical vibration system thiab acoustic system, thiab peb cov organically ua ke rau hauv ib qho kev sib koom ua ke thaum lub transducer ua haujlwm. Qhov no txiav txim siab txoj kev tshawb fawb rau nws yog fusion ntawm electronics Cov kev tshawb fawb ntawm science, mechanics, acoustics, thiab lwm yam, thiab los ntawm electro-mechanical-acoustic analogy, pab kom peb siv ib qho kev sib koom ua ke sib npaug electromechanical daim duab thiab sib npaug sib npaug kom yooj yim rau kev tshawb fawb tob.
Lub tshuab hluav taws xob ultrasonic converts 220V lub zog hluav taws xob rau hauv high-frequency tam sim no, thiab lub ultrasonic transducer converts high-frequency tam sim no mus rau hauv txhua yam kev co, ces amplifies (txo) lub amplitude los ntawm lub ultrasonic horn, thiab thaum kawg kis nws mus rau lub cuab tam lub taub hau rau kev ua hauj lwm. Ultrasonic transducers feem ntau muaj ob hom: magnetostrictive thiab piezoelectric ceramics.
Transducer muaj pes tsawg leeg
Central piezoelectric ceramic keeb
Pem hauv ntej thiab nram qab hlau npog
Prestressed ntsia hlau
Electrode ncoo
Rwb thaiv tsev raj
Qhov no hom ntawm sandwich transducer generates ruaj khov ultrasonic tsis thaum lub load hloov, uas yog feem ntau yooj yim thiab lub ntsiab txoj kev kom tau txais lub hwj chim ultrasonic tsav qhov chaw. Raws li kev tsim qauv sib txawv, cov ntaub ntawv ntawm ultrasonic transducers feem ntau yog:
Hom kab (NTK hom)
Inverted trumpet hom (Benengxin hom)
Steel rov qab cover
Aluminium clip hom
Ultrasonic transducers yog tsim rau ultrasonic vuam, ultrasonic txiav, ultrasonic kua kho, ultrasonic atomization spraying thiab ultrasonic hlau yaj kho.
