Kwinkalo yetekhnoloji yokufumanisa,umbhobho omkhulu wentsimbi ongenamthungoibhekisa kububanzi obungaphezulu kwe-160 mm.Umbhobho wensimbi ongenamthungo omkhulu zizinto ezibalulekileyo zepetroleum, ikhemikhali, i-thermal, ibhoyila, oomatshini, kunye noshishino lolwelo lwamanzi, njl. umbhobho wentsimbi ongenamthungo, kwaye ubonisa indlela yophuhliso lobukhulu obukhulu.Ngokukodwa ukuxhathisa umhlwa, ukumelana nokucudisa umbhobho we-oyile kunye nedayamitha enkulu ityhubhu yebhoyila yoxinzelelo oluphezulu kunye nombhobho wokuqhekeka kwe-oyile okumgangatho ophezulu, umbhobho wepetroleum kunye nepetrochemical, njl.Ke, ukuqinisekisa umgangatho weemveliso zovavanyo olungonakalisiyo ukubeka phambili iindlela kunye nobuchule kwisihloko esitsha.

Okwangoku, imveliso yesinyithi yaseTshayina yebhoyila yoxinzelelo oluphezulu lombhobho wentsimbi yokufunyaniswa isetyenziswa ikakhulu kwi-phi 160 mm ngezantsi kolubalulo, kunye nokwamkela ikhoyili yokufumanisa isiphene se-eddi yangoku okanye uhlobo oluzimeleyo lokukhongozela lwamanzi uhlobo lovavanyo lwe-ultrasonic.Ngaphezulu kwe-160 mm umbhobho wensimbi ongenamthungo ngokusebenzisa indlela yendabuko ye-eddy yangoku isetyenziselwa ukuvavanya, kukho iingxaki ezininzi, nazo ezingavumelekanga kumgangatho wesizwe.Ukuba sebenzisa uvavanyo lwe-ultrasonic yokuzimela, ngenxa yendlela yokufumanisa i-ultrasonic yobukho bobunzulu obuthile kwindawo eyimfama, ayinakuqinisekiswa ukuthembeka kweziphumo zovavanyo ngokubanzi.

Ngokusebenzisa i-coil yokubhaqwa kwe-eddy yangoku isangqa kumphezulu wombhobho wentsimbi.Isetyenziswa kwikhoyili, i-eddy yangoku yokufunyaniswa kwesiphako setyhubhu evavanyiweyo ubukhulu becala, kokukhona ukubonwa kwekhoyili, kokukhona inkulu indawo yeperipheral ye-SNR esezantsi.Kungenxa yesi sizathu, umgangatho wokuhlola umbhobho we-eddy wangoku, owamkelwa ngekhoyili, i-eddy yangoku yokufumanisa impazamo yobungakanani bayo boqoqosho lwangaphandle ayiyi kuba ngaphezu kwe-140 mm.Ukongeza, kumbhobho omkhulu wentsimbi ngovavanyo lohlobo, ityhubhu yentsimbi yemagnetization kunye ne-demagnetization, kukho ubunzima obuthile.

Uvavanyo lwetanki lwamanzi lwe-ultrasonic kukusebenzisa umbhobho wentsimbi ukuqhubela phambili, iprobe ye-ultrasonic ilungisiwe.Nge-sink kwaye ihlolwe iimpawu zombhobho wensimbi ogcwele amanzi ngaphantsi kokudibanisa, qinisekisa ukuba ubukhulu bomgca wokudibanisa buhlala bufana.Kodwa ukubonwa kwe-ultrasonic yeziphene zangaphakathi kumphezulu weziphene eziphambili zikhona kwindawo eyimfama kunye nexesha, ukukhokelela ekungakwazini ukubonwa, kunye nokuqhubela phambili okujikelezayo, i-30 m ukuya kwi-12 m ubude bombhobho wentsimbi kufuneka uthathe indawo yendawo, njl. iye yachaphazela ukhetho lwendlela yokukhangela umbhobho wentsimbi kunye nokukhuthaza.

Ke ngoko, uvavanyo lombhobho omkhulu wentsimbi ekhaya nakwamanye amazwe, ngokubanzi kusetyenziswa indlela yokuvuza yemagnethi okanye uvavanyo loxinzelelo lwamanzi.Ekhaya, akukho ntsebenzo ilungileyo kumbhobho omkhulu wentsimbi odayamitha oveliswe sisixhobo sokubona ukuvuza kombane, esakhe sasetyenziselwa ukungenisa elizweni.Ukungeniswa kwamanye amazwe isixhobo sokubona ukuvuza kwemagnethi kuyabiza, kunzima ukukwamkela kuninzi lwamashishini asekhaya;Kwaye ukusebenza okuphantsi kovavanyo loxinzelelo lwamanzi, ukuqina kwabasebenzi bukhulu, ngakumbi xa umqhubi uluvo loxanduva aluphezulu, uvavanyo loxinzelelo lwamanzi.Okubonakalayo, ukufezekiswa kokuhlolwa kwetyhubhu yentsimbi enomthungo omkhulu kuye kwaba yinto engxamisekileyo ukuba isonjululwe kwishishini lemibhobho yentsimbi.
