I-frequency ye-ultrasonic wave yi-frequency ye-vibration yomthombo wesandi.Into ebizwa ngokuba yi-vibration frequency linani leentshukumo eziphindaphindayo ngomzuzwana, iyunithi yiHertz, okanye iHertz ngokufutshane.I-Wave kukusasazwa kwe-vibration, oko kukuthi, i-vibration ihanjiswa kwi-frequency yokuqala.Ngoko ke ukuphindaphindwa kwamaza kukuphindaphinda kokungcangcazela komthombo wesandi.Amaza anokwahlulwa abe ziindidi ezintathu, ezizezi, amaza e-infrasonic, amaza e-acoustic, kunye namaza e-ultrasonic.Ukuphindaphinda kwamaza e-infrasound angaphantsi kwe-20Hz;ukuphindaphinda kwamaza omsindo yi-20Hz ~ 20kHz;Ubuninzi bamaza e-ultrasonic bungaphezulu kwe-20kHz.Phakathi kwazo, amaza e-infrasound kunye ne-ultrasound azivakali ngokubanzi kwiindlebe zabantu.Ngenxa yefrikhwensi ephezulu kunye nobude obufutshane, i-wave wave ye-ultrasonic inomkhombandlela olungileyo wokuhambisa kunye nekhono elinamandla lokungena.Yingakho umatshini wokucoca i-ultrasonic uyilwe kwaye wenziwe.
Umgaqo osisiseko:
Isizathu sokuba i-ultrasonic cleaner inokudlala indima yokucoca ukungcola kubangelwa oku kulandelayo: i-cavitation, i-acoustic flow, i-acoustic radiation pressure kunye ne-acoustic capillary effect.
Ngethuba lenkqubo yokucoca, umphezulu wokungcola uya kubangela ukutshatyalaliswa, ukukhupha, ukuhlukana, ukunyuswa kunye nokuchithwa kwefilimu yokungcola phezu komhlaba.Izinto ezahlukeneyo zineempembelelo ezahlukeneyo kumatshini wokuhlamba.Abacoci be-Ultrasonic ikakhulu baxhomekeke kwi-vibration ye-cavitation bubbles (i-cavitation bubbles engaqhamkanga) kwezo zimdaka ezingabotshwanga kakhulu.Emaphethelweni omdaka, ngenxa yokungcangcazela okuqinileyo kunye nokuqhunyiswa kwamabhulu e-pulsed, amandla okudibanisa phakathi kwefilimu engcolileyo kunye nobuso bento butshabalaliswa, enefuthe lokukrazula kunye nokukhupha.Uxinzelelo lwe-acoustic radiation kunye ne-acoustic capillary effect ikhuthaza ukungeniswa kolwelo lokuhlamba kwindawo encinci edibeneyo kunye neepores zento eza kucocwa, kunye nokuhamba kwesandi kunokukhawulezisa ukwahlukana kobumdaka ukusuka phezulu.Ukuba ukunamathela kokungcola kumphezulu kunamandla, i-micro-shock wave eyenziwa ngokuqhushumba kwe-bubble cavitation kufuneka isetyenziswe ukukhupha ukungcola phezu komhlaba.
Umatshini wokucoca i-ultrasonic ikakhulu usebenzisa "i-cavitation effect" ye-liquid-xa amaza e-ultrasonic ejikeleza emanzini, iamolekyu zamanzi ngamanye amaxesha zoluliwe kwaye ngamanye amaxesha zixinzelelwe, zenze imigodi emincinci engenakubalwa, ebizwa ngokuba yi "cavitation bubbles".Xa i-bubble ye-cavitation iqhuma ngokukhawuleza, i-wave ye-hydraulic shock wave (uxinzelelo lunokuphakama njenge-1000 atmospheres okanye ngaphezulu) luya kuveliswa.Ngaphantsi kwempembelelo eqhubekayo yolu xinzelelo, zonke iintlobo zokungcola ezinamathele kumphezulu we-workpiece ziya kuhlanjululwa;ngelo xesha, i-wave ye-ultrasonic Ngaphantsi kwesenzo, ukunyanzeliswa kwe-pulsating yokucoca ulwelo kuqiniswa, kwaye ukuchithwa, ukusabalalisa kunye ne-emulsification zikhawuleza, ngaloo ndlela zicoca i-workpiece.
Ukucoca okuluncedo:
a) Isiphumo esihle sokucoca, ukucoceka okuphezulu kunye nokucoceka okufanayo kwazo zonke izixhobo zokusebenza;
b) Isantya sokucoca sikhawuleza kwaye ukusebenza kakuhle kwemveliso kuphuculwe;
c) Akukho mfuneko yokuchukumisa ulwelo lokucoca ngezandla zomntu, ezikhuselekileyo nezithembekileyo;
d) Imingxuma enzulu, iintanda kunye neendawo ezifihlakeleyo ze-workpiece nazo zinokucocwa;
e) Akukho monakalo kumphezulu we-workpiece;
f) Gcina izinyibilikisi, amandla obushushu, indawo yokusebenza kunye nomsebenzi, njl.
