Sezvatinoziva tese, ruzha rwunonzwiwa nevanhu izviratidzo zvemafungu enzwi zvine frequency inotangira pa20 Hz kusvika 20,000 Hz. Mafungu enzwi ane frequency inodarika 20,000 Hz anonzi mafungu enzwi. Mafungu enzwi anopararira kwenguva refu muchimiro che "sine wave", achichinjana pakati peakasimba neasina simba paanofamba. Kana zviratidzo zvemafungu enzwi zvisina simba zvichishanda pamvura, zvinogadzira kumanikidzwa kwakati mukati memvura, zvichigadzira mabhuru madiki akawanda. Kusiyana neizvi, zviratidzo zvemafungu enzwi zvine simba zvinomanikidza zvakanaka pamvura, zvichiita kuti mabhuru madiki aya aputsike. Zvidzidzo zvakaratidza kuti kana mafungu enzwi achimhanya pamvura, kuputsika kwebhuru rimwe nerimwe kunogadzira mafungu ane simba kwazvo, achiperekedzwa nekupisa kwakanyanya nekukurumidza uye kumanikidzwa kwemhepo inosvika zviuru zvezviuru. Chiitiko ichi chinozivikanwa se "cavitation effect".Kuchenesa kwe ultrasonicinoshandisa mafungu ekuvhunduka anokonzerwa nemabubbles anoputika mumvura kuti ichenese uye ikweshe nzvimbo dzemukati nedzekunze dzezvishandiso zvebasa.
Mafungu eUltrasonic anogona kukamurwa kuita zvikamu zvitatu: mafungu einfrasonic, mafungu eruzha uye mafungu eultrasonic. Mafungu einfrasonic ari pasi pe20 Hz, ayo emafungu eruzha ari pakati pe20 Hz kusvika 20 kHz, uye mafungu eultrasonic ane mafungu anopfuura 20 kHz. Kazhinji, nzeve yemunhu haigone kuona mafungu einfrasonic nemafungu eultrasonic. Nekuda kwehuwandu hwayo hwepamusoro uye hupfupi hwewavelength, mafungu eultrasonic ane kupararira kwakanaka kwedivi uye kugona kwakasimba kwekupinda.
Pfungwa yekushanda kwemuchina wekuchenesa we ultrasonic ndeiyi inotevera: muchina wekushandura simba re acoustic kubva kunobva ultrasonic frequency ine simba guru kuita mechanical vibration. Kudengenyeka uku kunopfuudzwa nepamadziro etangi rekuchenesa, kuchiburitsa mafungu e ultrasonic mu cleansing solution iri mukati metangi. Pasi pekuvhenekerwa kwemafungu e ultrasonic, mabhuru madiki ari mumvura anoramba achidengenyeka pasi pesimba remafungu eruzha.
Kana kumanikidzwa kweruzha kana kuti simba reruzha rasvika padanho rakati, mabubbles anokura nekukurumidza uye anobva adonha kamwe kamwe. Panguva yekudonha kwemabubbles, mafungu ekudengenyeka anogadzirwa, zvichikonzera kumanikidzwa kuri pakati pe10¹²Pa kusvika 10¹³Pa yakatenderedza mabhurumu. Kumanikidzwa kukuru kunokonzerwa ne ultrasound cavitation kunopwanya tsvina isinganyungudike uye kunoiparadzira mumushonga.
Kune rumwe rutivi, mafungu e ultrasound anopwanya kubatana pakati pezvinhu zvakasvibiswa nepamusoro pezvinhu zvakacheneswa. Kune rumwe rutivi, anokonzera kutadza kuneta kwezvikamu zvakasvibiswa, zvichiita kuti zvibviswe. Kudengenyeka kwemabubbles egasi kunokwesha nzvimbo dzakasimba. Kana matombo aonekwa muzvikamu zvakasvibiswa, mabubbles anopinda mumaburi odedera kuti abvise tsvina. Kucheneswa kwemvura kunogonesawo kupararira nekukurumidza uye emulsification yemvura mbiri panzvimbo yadzo. Kana zvikamu zvakasimba zvakaputirwa nemafuta zvikanamatira pamusoro pezvinhu zvakacheneswa, mafuta acho anobviswa.yakasanganiswauye zvidimbu zvakasimba zvinodonha zvega. Sezvo mafungu e ultrasonic achifamba nemumushonga wekuchenesa, anogadzira kumanikidzwa kweruzha kwakanaka uye kusina kunaka, zvichigadzira majeti anochinjana zvakanaka nezvakaipa, zvichigadzira majeti anokanganisa zvinhu zvakacheneswa. Panguva iyi, mhedzisiro isiri yemutsara inogadzira kuyerera kwe acoustic uye kuyerera kwe micro-acoustic, uye ultrasonic cavitation inogadzira ma micro-jets anomhanyisa pa solid-liquid interface. Zvese izvi zvinogona kupwanya tsvina, kubvisa kana kushayisa simba mavhu epamusoro, kuwedzera kusanganiswa nekupararira, kukurumidzisa kunyungudika kwetsvina inonyunguduka, uye kuwedzera kushanda kwekuchenesa kwe chemical detergents.
Zvinogona kugumiswa kuti kuchenesa kunoitika chero kupi uko mvura inogona kusvika uye nzvimbo yekurira iripo. Iyi tekinoroji inonyanya kukodzera kuchenesa zvikamu zvine maumbirwo akaomarara pamusoro. Pamusoro pezvo, kushandiswa kwetekinoroji iyi kunogona kuderedza kushandiswa kwemakemikari anonyungudutsa, nokudaro zvichideredza zvakanyanya kusvibiswa kwezvakatipoteredza.
Nzira dzekudzivirira pakushandisa Ultrasonic Cleaners
Magetsi emuchina wekuchenesa we ultrasonic pamwe ne heater yawo yemagetsi anofanira kunge aine michina yakavimbika yekudzika pasi.
Usashandise ultrasonic cleaner usina mvura yekuchenesa. Usambobatidza ultrasonic switch kana tangi rekuchenesa risina kuzadzwa nemvura yakakwana yekuchenesa.
Pakuchenesa michina ine mayuniti ekudziyisa, switch yekudziyisa haifanirwe kuvhurwa kana pasina mvura mukati.
Usarove pasi petangi rekuchenesa nezvinhu zvinorema zvakaita sesimbi, kudzivirira kukuvara kwemachipisi etransducer.
Jenareta ye ultrasonic inofanira kubatanidzwa kune circuit yesimba ye 220V/50Hz yakazvimirira, ine voltage stabilizer inodarika 2000W.
Sukurudza pasi petangi rekuchenesa nguva dzose kudzivirira marara akawandisa uye kuungana kwetsvina.
Kana uchitsiva mvura yekuchenesa, tanga watanga ne ultrasonic system usati waisa zvinhu mutangi kuti zvicheneswe.
