Ukushisela i-arc kuyindlela esetshenziswa kabanzi ekwakhiweni kwamapayipi, ikakhulukazi ekusetshenzisweni okubandakanya ukuhlinzekwa kwamanzi angaphansi komhlaba. Kodwa-ke, njenganoma iyiphi inqubo yezimboni, iza nezinselelo zayo. Kule bhulogi, sizohlola izinselelo ezivamile ezibhekene nazo ngesikhathi sokushisela i-arc yamapayipi futhi sinikeze izixazululo ezisebenzayo ukuqinisekisa ukuthi kukhiqizwa umkhiqizo osezingeni eliphezulu nohlala isikhathi eside.
Ifektri yethu itholakala eCangzhou, eSifundazweni saseHebei futhi ibilokhu ihamba phambili ekukhiqizweni kwamapayipi kusukela ngo-1993. Ifektri yethu ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inabasebenzi abangochwepheshe abangu-680. Siyaziqhenya ngokusebenzisa ubuchwepheshe obuthuthukisiwe bokushisela i-spiral submerged arc, obuqinisekisa ikhwalithi ephezulu nokuqina kwemikhiqizo yethu. Lobu buchwepheshe obusezingeni eliphezulu buklanyelwe ukuhlangabezana nezindinganiso eziphakeme kakhulu zokuhlinzekwa kwamanzi angaphansi komhlaba, okwenza amapayipi ethu abe yisisombululo esithembekile nesihlala isikhathi eside sezinhlelo zokusebenza ezahlukahlukene.
Izinselele Ezivamile Ze-ArcIpayipi Elihlanganisiwe
1. Ikhwalithi yokushisela engaguquki: Enye yezinkinga ezivame kakhulu ekushiseleni i-arc ukuthola ikhwalithi yokushisela engaguquki. Ukwehluka kokufakwa kokushisa, isivinini sokuhamba, kanye ne-engeli ye-electrode kungabangela ukushisela okubuthakathaka noma okungaphelele.
Isixazululo: Ukusebenzisa izindlela zokulawula ikhwalithi eziqinile nokusebenzisa izinhlelo zokushisela ezenzakalelayo kungasiza ekugcineni ukuhambisana. Ukuqeqeshwa njalo kwabashisela ngemikhuba emihle kakhulu nokusebenzisa ubuchwepheshe bokuqapha obuthuthukisiwe nakho kungathuthukisa ikhwalithi yokushisela.
2. Ukuguquka nokugoba: Ukushisa okukhiqizwa ngesikhathi senqubo yokushisela kungabangela ukuthi ipayipi ligobe noma ligobe, okuholela ekungalungini kahle kanye nokwehluleka okungenzeka ekusetshenzisweni.
Isixazululo: Ukushisa ipayipi ngaphambi kokushisela nokusebenzisa amasu okubopha afanele kunganciphisa ukuphambuka. Ngaphezu kwalokho, ukusebenzisa amasu okushisa adlula ama-multi-pass kungasiza ekusabalaliseni ukushisa ngokulinganayo, kunciphisa ingozi yokugoba.
3. Ukumbozwa kanye Nokufakwa: Ukuba khona kwama-air pockets (ukumbozwa) noma izinto zangaphandle (okufakiwe) ku-weld kungalimaza ubuqotho bepayipi.
Isixazululo: Ukuqinisekisa indawo yokusebenza ehlanzekile nokusebenzisa izinto zokugcwalisa ezisezingeni eliphezulu kunganciphisa kakhulu ingozi yokubhoboka kanye nokufakwa. Ukuhlolwa njalo kwemishini yokushisela kanyeipayipi lokushisela i-arckubalulekile futhi ekugcineni inhlanzeko.
4. Ukuqhekeka: Ngenxa yokupholisa okusheshayo noma amasu okushisela angafanele, ukuqhekeka kungase kwenzeke, okuholela ekwahlulekeni kwesakhiwo sepayipi.
Isixazululo: Ukulawula amazinga okupholisa nokusebenzisa amasu okushisa kusengaphambili kungasiza ekuvimbeleni ukuqhekeka. Ngaphezu kwalokho, ukukhetha izinto zokugcwalisa ezifanele ezifanelana nezinto eziyinhloko kungathuthukisa ukumelana kokushiselwa ekuqhekekeni.
5. Ukungena Okwanele: Ukungena Okwanele kungabangela ilunga elibuthakathaka elingase lihluleke uma licindezelekile.
Isixazululo: Ukulungisa amapharamitha okushisela njenge-voltage kanye nogesi kungandisa ukujula kokushisela. Ukuhlolwa okuphelele kanye nokuhlolwa kokushisela kuzosiza ekuboneni nasekulungiseni noma yiziphi izinkinga ngaphambi kokuba ipayipi liqale ukusebenza.
Ekuphetheni
Esikhungweni sethu saseCangzhou, siyaqonda ukubaluleka kokunqoba lezi zinselele ezivamile zokushisela i-arc ukuze sikhiqize ipayipi elihlangabezana nezindinganiso eziphakeme kakhulu zekhwalithi nokuqina. Ngokusebenzisa ubuchwepheshe obuthuthukisiwe bokushisela i-arc engaphansi komhlaba, siqinisekisa ukuthi imikhiqizo yethu ayigcini nje ngokuthembeka kodwa futhi iyakwazi ukuhlangabezana nezidingo zezicelo ezahlukahlukene, ikakhulukazi ezinhlelweni zokuhlinzeka ngamanzi angaphansi komhlaba.
Ngokubhekana nalezi zinselele ngqo nokusebenzisa izixazululo ezisebenzayo, singaqhubeka nokuhlinzeka amakhasimende ethu ngemikhiqizo esezingeni eliphezulu ehlala isikhathi eside. Kungakhathaliseki ukuthi udinga amapayipi okwakha, ingqalasizinda noma izinhlelo zokusebenza zezimboni, ukuzibophezela kwethu ekhwalithini nasekusunguleni izinto ezintsha kuqinisekisa ukuthi uthola ikhambi elingcono kakhulu lezidingo zakho.
