Xa kufikwa kwimveliso yeepayipi zentsimbi zanamhlanje, i-ERW (Electric Resistance Welding) kunye ne-HFW (High-Frequency Welding) zezona ndlela zimbini ziqhelekileyo nezisebenzayo zokuvelisa. Nangona zinokubonakala zifana ekuqaleni, iipayipi zentsimbi ze-ERW kunye ne-HFW zahlukile kakhulu kwiindlela zazo zokuwelda, imilinganiselo yomgangatho, kunye ne-application scopes. Ukuqonda umahluko phakathi kweepayipi zentsimbi ze-ERW kunye ne-HFW kubalulekile ekukhetheni izixhobo ezifanelekileyo kwiprojekthi yakho.
Yintoni iUmbhobho we-ERW?
I-ERW (Ukuwelda kokumelana nombane)Imibhobho yenziwa ngokuqengqa ikhoyili yentsimbi ibe yimo ye-cylindrical okanye yesikwere uze udibanise imiphetho ngokusebenzisa umbane kunye noxinzelelo loomatshini.
Ubushushu obuveliswa kukumelana nombane kumthungo bubangela ukuba imiphetho yentsimbi inyibilike kwaye idibane, nto leyo edala i-weld eqhubekayo neqinileyo.
Imibhobho ye-ERW yaziwa ngezi zinto zilandelayo:
Ukuchaneka okunamandla okulinganayo
Ubukhulu bodonga obuhambelanayo
Ukusebenza kakuhle kweendleko kwimveliso enkulu
Le mibhobho isetyenziswa kakhulu kwiinkqubo zokubonelela ngamanzi, imibhobho enoxinzelelo oluphantsi, kunye nokusetyenziswa ngokubanzi kwezakhiwo.
Yintoni iUmbhobho we-HFW?
I-HFW (Ukuwelda Okuphindaphindekayo)umbhobho luhlobo lombhobho we-ERW osebenzisa umsinga oqhelekileyo ophezulu (ngaphezulu kwe-100 kHz) ukufudumeza nokuwelda imiphetho yentsimbi.
Ngokungafaniyo ne-ERW yendabuko, enokuxhomekeka kumbane ophantsi, i-HFW isebenzisa ubushushu obugxileyo nobunamandla aphezulu kwindawo elinganiselweyo, iqinisekisa indawo encinci echaphazelekileyo bubushushu (HAZ) kunye nokuthembeka okuphezulu kwe-weld.
Le nkqubo ibandakanya:
1. Ukubumba umcu wentsimbi ube yimo efunekayo (ujikeleze, ube sisikwere, okanye ube yingxande).
2. Ukufudumeza imiphetho ngokusebenzisa i-induction usebenzisa umsinga oqhelekileyo.
3. Ukuwelda ngoxinzelelo imiphetho eshushu ukuze kwenziwe ijoyinti egudileyo nengenamthungo.
Itekhnoloji ye-HFW yenza kube lula ukuwelda okucocekileyo nokuchanekileyo okune-oxidation encinci, okwenza ukuba ifaneleke kakuhle kwiityhubhu zentsimbi eziqinileyo kunye nombhobho wesikwere ochanekileyo.
Umahluko oPhambili Phakathi kweMibhobho ye-ERW kunye ne-HFW
Inkcazo yoBugcisa
Nangona zombini i-ERW kunye ne-HFW zixhomekeke ekuxhathiseni kombane ukuvelisa ubushushu, umbane kunye nokuphindaphinda okuthile kuyichaphazela kakhulu inkqubo.
Umgaqo wokuWelda we-ERW:
Umsinga ohamba rhoqo udlula kwintsimbi, udala ubushushu ecaleni kwejoyinti ngokuxhathisa. Imiphetho eshushu emva koko inyanzeliswa ukuba idibane ukuze yenze iqhina eliqinileyo.
Umgaqo wokuWelda we-HFW:
Isebenzisa i-high-frequency induction ukudala ubushushu obukhulu, obuxineneyo ngqo kumgca we-weld. Oku kuvelisa i-weld engcono, ekhazimlisiweyo ngakumbi engenasiphazamiso kangako sezinto ezibonakalayo.
Ngokwenyani, i-HFW imele uphuhliso oluntsonkothileyo lwe-ERW, oluyilelwe ukuphucula ukuthembeka kwe-weld, isantya semveliso, kunye nokusebenza kakuhle ngokubanzi.
Ukusetyenziswa kweeMbhobho ze-ERW kunye ne-HFW
Zombini iipayipi ze-ERW kunye ne-HFW zisetyenziswa kumacandelo amaninzi emizi-mveliso, kodwa usetyenziso lwazo luyahluka ngokuxhomekeke kwiimfuno zokusebenza.
Iipayipi zeNsimbi ze-ERW:
Imibhobho yamanzi negesi
I-scaffolding kunye nocingo
Iinkqubo zothutho ezinoxinzelelo oluphantsi
Izakhiwo zobunjineli ngokubanzi
Iipayipi zeNsimbi zeHFW:
Isakhiwo sentsimbi kunye nezakhelo zesakhiwo
Amacandelo angenanto anesikwere kunye noxande
Ukwenziwa kweemoto noomatshini
Iindlu zokugcina izityalo, ifenitshala, kunye nolwakhiwo oluchanekileyo
Ekubeni imibhobho ye-HFW inokufikelela kumandla aphezulu okuwelda kunye nokuchaneka okulinganayo, idla ngokukhethwa kakhulu kwizicelo zanamhlanje zokwakha kunye nobunjineli boomatshini.
Iinketho Zonyango Lomphezulu
Zombini iipayipi ze-ERW kunye ne-HFW ziyafumaneka ngeendlela ezahlukeneyo zokugqiba umphezulu:
Mnyama (onganyangwanga):Umphezulu omnyama wendalo, osetyenziselwa iindawo zangaphakathi okanye ezingaboliyo.
I-Hot-dip galvanized:I-zinc coating inika ukumelana nokugqwala okuphuculweyo, ilungele ii-ssytems zangaphandle okanye ezivezwe ngamanzi.
Ipeyintwe kwangaphambili okanye igqunywe ngomgubo:Isetyenziselwa ukutsala ubuhle okanye ukubonelela ngokhuseleko olongezelelweyo kumhlwa.
Iqela leTianjin Yuantai Derun,bonelela ngemibhobho yesikwere emnyama ye-HFW kunye neetyhubhu zentsimbi ezigayiweyo ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa.
Kwiiprojekthi ezifuna iityhubhu zesakhiwo ezinamandla aphezulu okanye iipayipi zesikwere ezichanekileyo, ukukhetha iipayipi ezihlanganisiweyo ze-HFW kuya kuqinisekisa ubomi benkonzo obude kunye nokusebenza okungcono kuneepayipi ze-ERW eziqhelekileyo.
