Njengoko sonke sisazi, izandi abantu abazivayo ziimpawu zamaza e-acoustic ezine-frequency ukusuka kwi-20 Hz ukuya kwi-20,000 Hz. Amaza e-acoustic ane-frequency engaphezulu kwe-20,000 Hz abizwa ngokuba ngamaza e-ultrasonic. Amaza e-acoustic asasazeka ixesha elide ngendlela ye-sine wave, etshintshana phakathi kwamandla kunye nobuthathaka njengoko ehamba. Xa iimpawu zamaza e-acoustic ezibuthathaka zisebenza kulwelo, zivelisa uxinzelelo oluthile olubi ngaphakathi kolwelo, zenze amaqamza amancinci amaninzi. Ngokwahlukileyo koko, iimpawu zamaza e-acoustic ezinamandla zinika uxinzelelo oluhle kulwelo, nto leyo ebangela ukuba la maqamza amancinci awe. Izifundo zibonise ukuba xa amaza e-ultrasound esebenza kulwelo, ukuwa kweqamza ngalinye kuvelisa amaza othuko anamandla kakhulu, ahamba namaqondo obushushu aphezulu ngoko nangoko kunye noxinzelelo olufikelela kumawaka ee-atmospheres. Le nto yaziwa ngokuba yi-"cavitation effect".Ukucoca nge-ultrasonicisebenzisa amaza othuko adalwa ngamaqamza aqhumayo kulwelo ukucoca nokucoca zombini iindawo zangaphakathi nezangaphandle zezinto zokusebenza.
Amaza e-ultrasonic anokwahlulwa abe ngamacandelo amathathu: amaza e-infrasonic, amaza esandi kunye namaza e-ultrasound. Amaza e-infrasonic angaphantsi kwe-20 Hz, lawo amaza esandi aqala kwi-20 Hz ukuya kwi-20 kHz, kwaye amaza e-ultrasound ane-frequency engaphezulu kwe-20 kHz. Ngokubanzi, indlebe yomntu ayinakukwazi ukubona amaza e-infrasonic kunye namaza e-ultrasound. Ngenxa ye-frequency yawo ephezulu kunye nobude obufutshane, amaza e-ultrasound abonisa ukusasazeka okuhle kwicala kunye nokukwazi ukungena ngamandla.
Umgaqo osebenzayo wesicoci se-ultrasonic ngolu hlobo lulandelayo: i-transducer iguqula amandla e-acoustic avela kumthombo we-ultrasonic frequency onamandla aphezulu abe yi-mechanical vibration. Olu vibration ludluliselwa ngodonga lwetanki yokucoca, lukhupha amaza e-ultrasonic kwisisombululo sokucoca ngaphakathi kwitanki. Phantsi kokukhanyiswa kwamaza e-ultrasonic, amaqamza amancinci kulwelo aqhubeka engcangcazela phantsi kwempembelelo yamaza esandi.
Xa uxinzelelo lwesandi okanye ubunzulu besandi bufikelela kwinqanaba elithile, amaqamza akhula ngokukhawuleza aze awe ngequbuliso. Ngexesha lokuwa kwamaqamza, kwenziwa amaza othuko, avelisa uxinzelelo oluqala kwi-10¹²Pa ukuya kwi-10¹³Ijikeleza amaqamza. Uxinzelelo olukhulu oludalwa yi-ultrasonic cavitation luqhekeza izinto ezingcolisayo ezinganyibilikiyo kwaye luzisasaze kwisisombululo.
Kwelinye icala, amaza e-ultrasound aphula ukunamathelana phakathi kwezinto ezingcolisayo nomphezulu wezinto ezicociweyo. Kwelinye icala, abangela ukungaphumeleli kokudinwa kweeleya ezingcolisayo, okwenza ziqhekeke. Ukungcangcazela kwamaqamza egesi kukhuhla iindawo eziqinileyo. Nje ukuba kuvele imingxunya kwiileya ezingcolisayo, amaqamza aya kungena kwizithuba aze angcangcazele ukuze asuse ukungcola. Ukukhupha i-cavitation kukwavumela ukusasazeka ngokukhawuleza kunye nokuhlanganiswa kwezinto ezimbini ezimanzi kwindawo yazo. Xa amaqhekeza aqinileyo agqunywe ngeoyile enamathela kumphezulu wezinto ezicociweyo, ioyile iyai-emulsifiedkwaye amasuntswana aqinileyo ayawa ngokwendalo. Njengoko amaza e-ultrasonic ehamba kwisisombululo sokucoca, avelisa uxinzelelo lwesandi olutshintshanayo nolungalunganga, enza iijethi ezichaphazela izinto ezicociweyo. Okwangoku, iziphumo ezingezizo ezithe ngqo zivelisa ukusasazwa kwe-acoustic kunye nokusasazwa kwe-micro-acoustic, kwaye i-ultrasonic cavitation idala ii-micro-jets ezikhawulezayo kwi-interface ye-solid-liquid. Zonke ezi ziphumo zinokuqhekeza ukungcola, zisuse okanye zenze buthathaka iileya zomphezulu wokungcola, ziphucule ukuxukuxa kunye nokusasazwa, zikhawulezise ukunyibilika kokungcola okunyibilikayo, kwaye zinyuse ukusebenza kokucoca kweesepha zamakhemikhali.
Kungagqitywa kwelokuba ukucoca kwenzeka naphi na apho ulwelo lunokufikelela khona kwaye kukho indawo yesandi. Le teknoloji ifanelekile ngokukodwa ekucoceni iindawo ezinemilo yomphezulu entsonkothileyo kakhulu. Ukongeza, ukusetyenziswa kwale teknoloji kunokunciphisa ukusetyenziswa kwezinyibilikisi zeekhemikhali, ngaloo ndlela kunciphise kakhulu ungcoliseko lokusingqongileyo.
Amanyathelo okuzikhusela xa usebenzisa ii-Ultrasonic Cleaners
Izixhobo zombane zesixhobo sokucoca i-ultrasonic kunye ne-heater yaso yombane kufuneka zixhotyiswe ngezixhobo zokumisa umhlaba ezinokuthenjwa.
Musa ukusebenzisa isicoci se-ultrasonic ngaphandle kolwelo lokucoca. Ungaze uvule iswitshi ye-ultrasonic ukuba itanki yokucoca ayizaliswanga ngesicoci esaneleyo sokucoca.
Kwizixhobo zokucoca ezifakelwe iiyunithi zokufudumeza, iswitshi yokufudumeza akufuneki isebenze xa kungekho ulwelo ngaphakathi.
Musa ukubetha ezantsi kwetanki yokucoca ngezinto ezinzima ezifana nezixhobo zentsimbi, ukuze uthintele ukonakala kwee-transducer chips.
Ijenereyitha ye-ultrasonic kufuneka iqhagamshelwe kwisekethe yamandla ye-220V/50Hz ezimeleyo, exhotyiswe nge-voltage stabilizer elinganiswe ngaphezulu kwe-2000W.
Hlamba umzantsi wetanki yokucoca rhoqo ukuze uphephe ukungcola okuninzi kunye nokuqokelelwa kokungcola.
Xa utshintsha ulwelo lokucoca, qala inkqubo ye-ultrasonic kuqala ngaphambi kokuba ufake izinto etankini ukuze zicocwe.
