(1) Ukukhethwa kwamandla
Ukucocwa kwe-ultrasonic ngamanye amaxesha kusebenzisa amandla aphantsi kwaye kuthatha ixesha elide ngaphandle kokususa ukungcola.Kwaye ukuba amandla afikelela kwixabiso elithile, ukungcola kuya kususwa ngokukhawuleza.Ukuba amandla akhethiweyo makhulu kakhulu, amandla e-cavitation aya kwandiswa kakhulu, kwaye umphumo wokucoca uya kuphuculwa, kodwa ngeli xesha, iindawo ezichanekileyo nazo zineendawo zokubola, kunye ne-cavitation ye-vibrating plate ezantsi kwe-corrosion. umatshini wokucoca unzulu, i-corrosion yamanzi iphinda inyuke, kwaye inamandla Ngaphantsi kwamandla, i-cavitation corrosion ephantsi kwamanzi ibaluleke kakhulu, ngoko ke amandla e-ultrasonic kufuneka akhethwe ngokubhekiselele kusetyenziso lwangempela.
(2) Ukukhethwa kwe-ultrasonic frequency
Isantya sokucoca i-ultrasonic sisuka kwi-28 kHz ukuya kwi-120 kHz.Xa usebenzisa amanzi okanye i-ejenti yokucoca amanzi, amandla okucoca ngokomzimba okubangelwa yi-cavitation ngokucacileyo kunenzuzo kwii-frequencies eziphantsi, ngokubanzi malunga ne-28-40 kHz.Ukucoca iindawo ezinezikhewu ezincinci, i-slits kunye nemingxuma enzulu, kungcono ukusebenzisa i-frequency ephezulu (ngokubanzi ngaphezu kwe-40kHz), kunye namakhulu e-kHz.Uphindaphindo lulingana noxinaniso kwaye luthelekiseka ngokuphambeneyo namandla.I-frequency ephezulu, i-high density yokucoca kunye namandla amancinci okucoca;i-frequency ephantsi, incinci encinci yokucoca kunye namandla amakhulu okucoca.
(3) Ukusetyenziswa kweengobozi zokucoca
Xa ucoca iindawo ezincinci, iibhasikithi ze-mesh zihlala zisetyenziswa, kwaye ingqalelo ekhethekileyo kufuneka ihlawulwe kwi-ultrasonic attenuation ebangelwa yi-mesh.Xa i-frequency ingu-28khz, kungcono ukusebenzisa i-mesh engaphezu kwe-10mm.
(4) Ukucoca ubushushu bolwelo
Iqondo lokushisa elifanelekileyo lokucoca isisombululo sokucoca amanzi ngu-40-60 ℃, ngakumbi kwimozulu ebandayo, ukuba ukushisa kwesisombululo sokucoca kuphantsi, umphumo we-cavitation ubi, kwaye umphumo wokucoca nawo ubi.Ngoko ke, abanye oomatshini bokucoca bavuthela ucingo lokufudumeza ngaphandle kwe-cylinder yokucoca ukulawula ubushushu.Xa izinga lokushisa liphakama, i-cavitation kulula ukwenzeka, ngoko umphumo wokucoca ungcono.Xa iqondo lokushisa liqhubeka nokunyuka, uxinzelelo lwegesi kwi-cavitation luyanda, lubangela ukuba impembelelo yomsindo wefuthe iyancipha, kwaye umphumo uya kuba buthathaka.
(5) Ukumiselwa komthamo wokucoca ulwelo kunye nendawo yokucoca iindawo
Ngokuqhelekileyo, kungcono ukuba umgangatho wokucoca ulwelo ungaphezulu kwe-100mm ngaphezu komphezulu we-vibrator.Ngenxa yokuba umatshini wokucoca i-frequency single-frequency echatshazelwa yi-stand wave field, i-amplitude kwi-node incinci, kwaye i-amplitude kwi-amplitude ye-wave inkulu, ekhokelela ekucoceni okungalinganiyo.Ngoko ke, ukhetho olufanelekileyo lwezinto zokucoca kufuneka lubekwe kwi-amplitude.(Olona luhlu lusebenzayo luyi-3-18 cm)
(6) Inkqubo yokucoca i-ultrasonic kunye nokukhethwa kwesisombululo sokucoca
Ngaphambi kokuthenga inkqubo yokucoca, uhlalutyo olulandelayo lwesicelo kufuneka lwenziwe kwiindawo ezihlambulukileyo: Ukumisela ukubunjwa kwezinto eziphathekayo, isakhiwo kunye nobuninzi beendawo ezihlambulukileyo, ukuhlalutya kunye nokucacisa ukungcola okuza kususwa, ezi zonke zithatha isigqibo sokuba yeyiphi indlela yokucoca. kwaye ugwebe isicelo Izisombululo zokucoca ngamanzi nazo ziyimfuneko yokusetyenziswa kwe-solvents.Inkqubo yokugqibela yokucoca kufuneka iqinisekiswe ngokucoca imifuniselo.Ngaloo ndlela kuphela inkqubo yokucoca efanelekileyo, inkqubo yokucoca eyenziwe ngokwengqiqo kunye nesisombululo sokucoca.Ukuqwalasela impembelelo yeempawu ezibonakalayo zokucoca ulwelo ekucoceni kwe-ultrasonic, uxinzelelo lomphunga, ukunyanzeliswa komphezulu, i-viscosity kunye nokuxinana kufuneka kube yizona zinto zibalulekileyo ezichaphazelayo.Ubushushu bunokuchaphazela ezi zinto, ngoko kuchaphazela nokusebenza kakuhle kwe-cavitation.Nayiphi na inkqubo yokucoca kufuneka isebenzise ulwelo lokucoca.
