Izindaba - Inqubo Yokukhiqiza I-Ductile Iron Pipe: Inqubo Eqinile Yokusakaza Amapayipi Ekhwalithi Ephezulu

Ekwenziweni kwezimboni zanamuhla, amapayipi ensimbi e-ductile asetshenziswa kakhulu ekunikezeni amanzi, ukugeleza kwamanzi, ukudluliswa kwegesi kanye neminye imikhakha ngenxa yezakhiwo zabo ezinhle kakhulu zemishini kanye nokumelana nokugqwala. Ukuze kuqinisekiswe izinga eliphezulu nokuthembeka okuphezulu kwamapayipi ensimbi ye-ductile, inqubo yabo yokukhiqiza kufanele ilawulwe ngokuqinile futhi icutshungulwe kahle. Kusukela ekulungiseni nasekufakweni kwe-spheroidization yensimbi encibilikisiwe, ukuya ekubunjweni okumaphakathi, ukuhlanganisa, kanye nezinqubo zokuqeda njengokufafaza kwe-zinc, ukugaya, ukuhlola ingcindezi ye-hydraulic, ulwelwesi lukasimende kanye nokufutha ngetiyela, sonke isixhumanisi sibalulekile. Lesi sihloko sizokwethula inqubo yokukhiqizaI-Ductile Cast Iron Pipengokuningiliziwe, futhi ubonise indlela yokuqinisekisa ukuthi ipayipi ngalinye lingahlangabezana nezindinganiso zamazwe ngamazwe kanye nezidingo zangempela zokusetshenziswa ngokuphathwa kwesayensi nezindlela zobuchwepheshe ezithuthukisiwe, futhi linikeze iziqinisekiso zengqalasizinda ezinokwethenjelwa zemiklamo ehlukahlukene yobunjiniyela.

1. Ukulungiswa Kwensimbi Encibilikisiwe
Ukulungiselela Iron Encibilikisiwe kanye Ne-Spheroidization: Khetha insimbi yengulube yekhwalithi ephezulu njengento eluhlaza, njengensimbi yezinga eliphezulu ye-ductile casting pig iron, enezici ze-P ephansi, i-S ephansi, ne-Ti ephansi. Ngokwezicaciso zobubanzi bepayipi okufanele bukhiqizwe, izinto zokusetshenziswa ezihambisanayo zengezwa esithandweni somlilo esiphakathi, esishintsha insimbi encibilikisiwe futhi siyishise ekushiseni okudingwa yinqubo, bese sengeza i-ejenti ye-spheroidizing ye-spheroidization.
Ukulawula Ikhwalithi Yensimbi Eshisayo: Enqubweni yokulungiswa kwensimbi encibilikisiwe, ikhwalithi nokushisa kwesixhumanisi ngasinye kulawulwa ngokuqinile. Isithando somlilo ngasinye nesaka ngalinye lensimbi encibilikisiwe kufanele kuhlaziywe nge-spectrometer yokufunda eqondile ukuze kuqinisekiswe ukuthi insimbi encibilikisiwe ihlangabezana ngokugcwele nezidingo zokubunjwa.

2. I-Centrifugal Casting
I-Metal Mold Centrifuge Casting epholile ngamanzi: I-centrifuge yensimbi epholile ngamanzi isetshenziselwa ukusakaza. Insimbi encibilikisiwe enezinga eliphezulu lokushisa ihlale ithululelwa esikhunjini sepayipi elijikelezayo elinesivinini esikhulu. Ngaphansi kwesenzo samandla e-centrifugal, insimbi encibilikisiwe isakazwa ngokulinganayo odongeni lwangaphakathi lwesikhunta sepayipi, futhi insimbi encibilikisiwe iqiniswa ngokushesha ngokupholisa kwamanzi ukuze yakhe ipayipi lensimbi edonsa amanzi. Ngemva kokuqedwa kokulingisa, ipayipi elilingi liyahlolwa ngokushesha futhi likalwe ukuze kutholwe ukonakala ukuze kuqinisekiswe ikhwalithi yepayipi ngalinye.
Ukwelashwa Kwe-Anealing: AbalingisiIshubhu yensimbibese ifakwa esithandweni somlilo ukuze kusetshenziswe ukwelashwa ukuze kuqedwe ingcindezi yangaphakathi ekhiqizwa phakathi nenqubo yokuphonsa futhi kuthuthukiswe ukwakheka kwe-metallographic kanye nezakhiwo zemishini zepayipi. .
Ukuhlolwa kokusebenza: Ngemva kokudonsa, ipayipi lensimbi edonsa amanzi lingaphansi kochungechunge lokuhlolwa kokusebenza okuqinile, okuhlanganisa ukuhlolwa kokuhlehlisa, ukuhlola ukubukeka, ukuhlolwa kokucaba, ukuhlolwa okuqinile, ukuhlolwa kokuqina, ukuhlolwa kwe-metallographic, njll. Amapayipi angahlangabezani nezimfuneko azochithwa futhi ngeke angene enqubweni elandelayo.

3. Ukuqeda
Ukufafaza kweZinc: Ipayipi le-iron ductile liphathwa nge-zinc ngokusebenzisa umshini we-spray kagesi ophezulu we-voltage. Isendlalelo se-zinc singakha ifilimu yokuzivikela ebusweni bepayipi ukuze kuthuthukiswe ukumelana nokugqwala kwepayipi. .
Ukugaya: UyafanelekaIpayipi le-Ductile Iron Drainageathunyelwa esiteshini sesithathu sokugaya ukuze ahlolwe ukubukeka kwawo, futhi isokhethi, i-spigot nodonga lwangaphakathi lwepayipi ngalinye luyapholishwa futhi luhlanzwe ukuze kuqinisekiswe ukucaba nokuqedwa kwendawo yepayipi nokuvaleka kwesixhumi esibonakalayo.
Ukuhlolwa kwe-Hydrostatic: Amapayipi alungisiwe angaphansi kokuhlolwa kwe-hydrostatic, futhi ingcindezi yokuhlola iphakeme ngo-10kg/cm² kunezinga le-ISO2531 lamazwe ngamazwe kanye nezinga laseYurophu, ukuze kuqinisekiswe ukuthi amapayipi angakwazi ukumelana nokucindezela okwanele kwangaphakathi futhi ahlangabezane nezidingo zengcindezi ekusebenziseni kwangempela. .
I-Cement Lining: Udonga lwangaphakathi lwepayipi luboshwe nge-centrifugally nge-cement ngomshini we-double-station samente. Udaka lukasimende olusetshenzisiwe luye lwahlolwa ngokuqinile ikhwalithi nokulawulwa kwesilinganiso. Yonke inqubo yokumboza ilawulwa yikhompyutha ukuze kuqinisekiswe ukufana kwekhwalithi nokuzinza kolwelwesi lukasimende. Amapayipi afakwe usimende ayaphulukiswa njengoba kudingeka ukuze kuqiniswe ngokugcwele ulwelwesi lukasimende. .
Ukufafaza kwe-Asphalt: Amapayipi eselashiwe aqale ashiselwe phezulu, bese kuthi i-asphalt ifuthwe ngesifutho esizenzakalelayo sesiteshi esiphindwe kabili. Ukufakwa kwe-asphalt kwandisa ikhono lokulwa nokugqwala kwamapayipi futhi kwandisa impilo yesevisi yamapayipi. .
Ukuhlola Okokugcina, Ukupakisha kanye Nesitoreji: Amapayipi afuthwe ngetiyela ahlolwa okokugcina. Amapayipi afaneleke ngokugcwele kuphela angafuthwa ngamamaki, bese epakishwa futhi agcinwe njengoba kudingeka, alinde ukuthunyelwa ezindaweni ezihlukahlukene ukuze asetshenziswe.
