Mitar kalaman ultrasonic shine mitar girgiza tushen sauti.Abin da ake kira mitar girgiza shine adadin motsin motsi a cikin dakika daya, sashin shine Hertz, ko Hertz a takaice.Wave shine yaduwa na vibration, wato, ana watsa vibration a mitar asali.Don haka mitar igiyar igiyar ita ce mitar girgiza tushen sauti.Ana iya raba igiyoyin ruwa zuwa nau'i uku, wato infrasonic taguwar ruwa, raƙuman sauti, da raƙuman ruwa na ultrasonic.Yawan raƙuman ruwa na infrasound yana ƙasa da 20Hz;yawan raƙuman sauti shine 20Hz ~ 20kHz;mitar ultrasonic taguwar ruwa yana sama da 20kHz.Daga cikin su, infrasound taguwar ruwa da duban dan tayi gabaɗaya ba sa jin kunnen ɗan adam.Saboda tsayin mita da ɗan gajeren zango, igiyar ultrasonic tana da kyakkyawan jagorar watsawa da ƙarfi mai ƙarfi.Wannan shine dalilin da ya sa aka tsara na'urar tsaftacewa na ultrasonic.
Ka'ida ta asali:
Dalilin da yasa mai tsabtace ultrasonic zai iya taka rawa na tsaftacewa datti yana haifar da haka: cavitation, acoustic flow, acoustic radiation matsa lamba da kuma acoustic capillary sakamako.
A lokacin aikin tsaftacewa, datti na datti zai haifar da lalacewa, peeling, rabuwa, emulsification da rushewar fim din datti a saman.Abubuwa daban-daban suna da tasiri daban-daban akan injin wanki.Ultrasonic cleaners, yafi dogara a kan vibration na cavitation kumfa (unexploded cavitation kumfa) ga wadanda datti da ba su da tam a haɗe.A gefen datti, saboda tsananin rawar jiki da busassun kumfa, ƙarfin haɗin gwiwa tsakanin fim ɗin datti da saman abu ya lalace, wanda ke da tasirin tsagewa da kwasfa.Acoustic radiation matsa lamba da acoustic capillary sakamako na inganta kutsawa na ruwan wanka a cikin kananan recessed saman da pores na abin da za a tsabtace, da kuma sauti kwarara iya hanzarta rabuwa da datti daga saman.Idan manne da datti zuwa saman yana da ɗan ƙarfi, ƙaramar girgizar da ke haifar da fashewar kumfa na cavitation yana buƙatar amfani da shi don cire datti daga saman.
Na'ura mai tsaftacewa na ultrasonic yana amfani da "sakamako na cavitation" na ruwa-lokacin da raƙuman ruwa na ultrasonic suna haskakawa a cikin ruwa, kwayoyin ruwa wani lokaci suna shimfiɗawa kuma wani lokacin matsawa, suna samar da ƙananan ƙananan cavities, abin da ake kira "cavitation kumfa".Lokacin da kumfa cavitation ya fashe nan take, za a haifar da girgizar girgizar hydraulic na gida (matsi na iya kaiwa sama da yanayi 1000 ko fiye).A ƙarƙashin ci gaba da tasirin wannan matsa lamba, kowane nau'in datti da ke manne da saman kayan aikin za a cire shi;A lokaci guda, da ultrasonic kalaman A karkashin aikin, da pulsating stirring na tsaftacewa ruwa ne intensious, da kuma rushewa, watsawa da emulsification suna kara, game da shi tsaftacewa da workpiece.
Amfanin tsaftacewa:
a) Kyakkyawan sakamako mai tsabta, tsafta mai girma da tsafta iri ɗaya na duk kayan aiki;
b) Gudun tsaftacewa yana da sauri kuma an inganta ingantaccen samarwa;
c) Babu buƙatar taɓa ruwan tsaftacewa tare da hannun mutum, wanda yake da aminci kuma abin dogara;
d) Hakanan za'a iya tsaftace ramuka masu zurfi, ramuka da ɓoyayyun sassan aikin aikin;
