Ha ho tluoa tlhahisong ea liphaephe tsa tšepe tsa sejoale-joale, ERW (Electric Resistance Welding) le HFW (High-Frequency Welding) ke tse peli tsa mekhoa e tloaelehileng le e sebetsang hantle ea tlhahiso. Leha li ka bonahala li tšoana qalong, liphaephe tsa tšepe tsa ERW le HFW li fapana haholo ka mekhoa ea tsona ea ho tjheseletsa, litekanyetso tsa boleng, le li-scope tsa ts'ebeliso. Ho utloisisa phapang lipakeng tsa liphaephe tsa tšepe tsa ERW le HFW ho bohlokoa bakeng sa ho khetha thepa e loketseng projeke ea hau.
Ke EngPhaephe ea ERW?
ERW (Ho Wellisa ka Kganyetso ya Motlakase)Liphaephe li etsoa ka ho phutholla khoele ea tšepe hore e be sebopeho sa cylindrical kapa sekwere ebe li kopanya mathoko ka ho sebelisa motlakase le khatello ea mechine.
Mocheso o hlahisoang ke khanyetso ea motlakase morong o etsa hore mathoko a tšepe a qhibilihe le ho kopana, e leng se etsang hore ho be le weld e tsitsitseng le e tiileng.
Liphaephe tsa ERW li tsebahala ka:
Ho nepahala ho matla ha tekanyo
Botenya ba lebota bo tsitsitseng
Bokgoni ba ditjeo bakeng sa tlhahiso e kgolo
Liphaephe tsena li sebelisoa haholo lits'ebetsong tsa phepelo ea metsi, liphaephe tse nang le khatello e tlase, le lits'ebetsong tse akaretsang tsa meaho.
Ke EngPhaephe ea HFW?
HFW (Ho Welding ka Maqhubu a Phahameng)phaephe ke mofuta oa phaephe ea ERW e sebelisang motlakase o phahameng (kaholimo ho 100 kHz) ho futhumatsa le ho tjheseletsa mathoko a tšepe.
Ho fapana le ERW ea setso, e ka itšetlehang ka motlakase o fokolang, HFW e sebelisa mocheso o tsepamisitsoeng, o matla haholo sebakeng se lekanyelitsoeng, e netefatsa sebaka se senyenyane se amehileng ke mocheso (HAZ) le botšepehi bo phahameng ba weld.
Ts'ebetso e kenyelletsa:
1. Ho bopa mothapo wa tshepe hore e be sebopeho se hlokahalang (se chitja, sekwere, kapa se kgutlonnetsepa).
2. Ho futhumatsa mathoko ka ho sebedisa motlakase o nang le maqhubu a phahameng.
3. Ho tjheseletsa ka kgatello mathoko a futhumetseng ho etsa lenonyello le boreleli, le se nang sekoli.
Theknoloji ea HFW e nolofalletsa li-weld tse hloekileng le tse nepahetseng haholoanyane tse nang le oxidation e fokolang, e leng se etsang hore e lokele hantle lipeipi tsa tšepe tse nang le sebopeho se matla le phaephe e nang le sekwere se nepahetseng.
Phapang e Khōlō Pakeng tsa Liphaephe tsa ERW le HFW
Tlhaloso ea Tekheniki
Leha ERW le HFW ka bobeli li itšetlehile ka khanyetso ea motlakase ho hlahisa mocheso, hona joale le maqhubu a itseng li susumetsa ts'ebetso haholo.
Molao-motheo oa ho Welding oa ERW:
Motlakase o nang le maqhubu a tlase o phalla ka hara mothapo wa tshepe, o baka mocheso ho pholletsa le lenonyeletso ka ho hanyetsa. Meeli e futhumaditsweng ebe e qobellwa ho kopana ho theha tlamo e tiileng.
Molao-motheo oa ho Tjheseletsa oa HFW:
E sebelisa induction ea maqhubu a phahameng ho hlahisa mocheso o matla, o kopaneng ka kotloloho moleng oa weld. Sena se hlahisa weld e ntle, e bentšitsoeng haholoanyane e nang le khopamiso e nyane haholo ea thepa.
Ha e le hantle, HFW e emela phetoho e rarahaneng haholoanyane ea ERW, e entsoeng ho ntlafatsa botšepehi ba weld, lebelo la tlhahiso, le katleho ea ts'ebetso ka kakaretso.
Litšebeliso tsa Liphaephe tsa ERW le HFW
Liphaephe tsa ERW le HFW ka bobeli li sebelisoa liindastering tse fapaneng, empa lits'ebetso tsa tsona lia fapana ho latela litlhoko tsa ts'ebetso.
Liphaephe tsa Tšepe tsa ERW:
Liphaephe tsa metsi le khase
Sekafole le terata
Mekhoa ea lipalangoang tse nang le khatello e tlase
Meaho e akaretsang ea boenjiniere
Liphaephe tsa Tšepe tsa HFW:
Sebopeho sa tšepe le liforeimi tsa moaho
Likarolo tse sekoere le tse khutšoane tse se nang letho
Tlhahiso ea likoloi le mechini
Matlo a polokelo ea limela, thepa ea ka tlung le kaho e nepahetseng
Kaha liphaephe tsa HFW li ka finyella matla a ho tjheseletsa le ho nepahala ha boholo ba tsona, hangata li khethoa lits'ebetsong tsa kaho tsa sejoale-joale le boenjiniere ba mechini.
Likhetho tsa Kalafo ea Bokaholimo
Liphaephe tsa ERW le HFW ka bobeli li fumaneha ka liphetho tse fapaneng tsa bokaholimo:
Ntšo (e sa phekoloang):Bokaholimo bo lefifi ba tlhaho, bo sebelisetsoang tikoloho ea ka tlung kapa e sa senyeheng.
Ho qoelisa ka mabati a chesang:Sekoahelo sa zinki se fana ka khanyetso e ntlafalitsoeng ea mafome, e loketseng li-ssytem tsa kantle kapa tse pepesehileng metsi.
E pentiloe esale pele kapa e koahetsoeng ka phofo:E sebelisetsoa botle bo botle kapa ho fana ka tšireletso e eketsehileng khahlanong le mafome.
Sehlopha sa Tianjin Yuantai Derun,fana ka liphaephe tse ntsho tsa HFW tse sekwere le liphaephe tsa tšepe tse entsoeng ka lepolanka ho fihlela litlhoko tse fapaneng tsa ts'ebeliso.
Bakeng sa merero e hlokang liphaephe tsa sebopeho tse matla haholo kapa liphaephe tse sekwere tse nepahetseng, ho khetha liphaephe tse welletsoeng ka HFW ho tla netefatsa bophelo bo bolelele ba ts'ebeletso le ts'ebetso e betere ho feta liphaephe tsa ERW tse tloaelehileng.
