I-Ultrasonic transducer iyidivayisi yokuguqula amandla eguqula amasignali kagesi ashintshanayo abe amasignali acoustic noma amasignali acoustic abe amasignali kagesi ngaphakathi kwe-ultrasonic frequency range. Kuyidivayisi eyisihluthulelo emishinini ye-ultrasonic, ngakho-ke kungakhathaliseki ukuthi isendleleni yokudlulisa noma inqubo Idizayini nezinye izinhlangano zithole ukunakwa isikhathi eside.
Imingcele yokusebenza yama-transducers e-ultrasonic
I-Ultrasonic transducer iyidivayisi yokuguqula amandla, futhi incazelo nokusebenza kwayo nokuhlola kudinga imingcele eminingi. Imingcele yesici ye-transducer ye-ultrasonic ihlanganisa imvamisa ye-resonance, i-frequency bandwidth, i-electromechanical coupling coefficient, ukusebenza kahle kwe-electroacoustic, mechanical quality factor, izici ze-impedance, izici zokuvama kwezimpawu, ukuqondisa, ukudlulisa nokwamukela ukuzwela, njll. Ukuze uthole ama-ultrasonic transducers, i-wide frequency band kanye nokuzwela okuphezulu nokulungiswa kuyadingeka. Ngakho-ke, enqubweni ethile yokuklama ye-transducer, imingcele efanele ye-transducer kufanele yenziwe ngokuvumelana nesicelo esithile Umklamo onengqondo.
Indlela yokuhlaziya ye-ultrasonic transducer
Ama-transducer e-Ultrasonic ahlanganisa isistimu yesifunda, isistimu yokudlidliza eyimishini kanye nesistimu ye-acoustic, futhi lezi zintathu zihlanganiswa ngokwemvelo zibe yinto ehlangene lapho i-transducer isebenza. Lokhu kunquma indlela yocwaningo yalo ukuhlanganiswa kwezinto zikagesi Izindlela zocwaningo zesayensi, izinsimbi, i-acoustics, njll., futhi ngokusebenzisa isifaniso se-electro-mechanical-acoustic, zenza laba abathathu basebenzise umdwebo olinganayo olinganayo we-electromechanical kanye nezibalo ezilinganayo ukuze kwenziwe kalula ucwaningo olujulile.
I-generator ye-ultrasonic iguqula amandla amakhulu angu-220V abe yi-high-frequency current, futhi i-transducer ye-ultrasonic iguqula i-high-frequency current ibe yi-vibration mechanical, bese ikhulisa (inciphisa) i-amplitude ngokusebenzisa uphondo lwe-ultrasonic, futhi ekugcineni idlulisele ekhanda lamathuluzi ukuze lisebenze. Ama-transducer e-Ultrasonic ngokuvamile anezinhlobo ezimbili: i-magnetostrictive kanye ne-piezoelectric ceramics.
Ukwakhiwa kwe-Transducer
I-central piezoelectric Ceramic element
Izembozo zensimbi zangaphambili nangemuva
Isikulufu esicindezelwe
Iphedi ye-electrode
Ishubhu ye-insulation
Lolu hlobo lwe-transducer yesangweji lukhiqiza amaza azinzile we-ultrasonic lapho umthwalo ushintsha, okuyindlela eyisisekelo neyinhloko yokuthola umthombo wamandla we-ultrasonic drive. Ngokusho kwemiklamo ehlukene, amafomu ama-transducers e-ultrasonic ikakhulukazi:
Uhlobo lwekholomu (uhlobo lwe-NTK)
Uhlobo lwecilongo oluhlanekezelwe (uhlobo lwe-Benengxin)
Ikhava yangemuva yensimbi
Uhlobo lwesiqeshana se-Aluminium
Ama-transducers e-Ultrasonic afaneleka kakhulu ukushiselwa kwe-ultrasonic, ukusika kwe-ultrasonic, ukwelashwa kwe-liquid ye-ultrasonic, ukufafaza kwe-atomization kwe-ultrasonic kanye nokwelashwa kwe-ultrasonic metal melt.
