Iindaba - iDuctile Iron Pipe: Eyona ndawo ingundoqo kwiiNkqubo zeMibhobho yale mihla

Umbhobho wentsimbi weNtsintsi, yenziwe ngentsimbi etyhidiweyo njengesiseko sezinto. Ngaphambi kokugalelwa, i-magnesium okanye i-magnesium yomhlaba enqabileyo kunye nezinye i-spheroidizing agents zongezwa kwintsimbi etyhidiweyo ukuze i-spheroidize igraphite, kwaye umbhobho uveliswa ngoluhlu lweenkqubo ezinzima. Ubunqabileyo bentsimbi ye-ductile kukuba ininzi okanye yonke i-graphite ye-precipitated ikwifom ye-spherical, kwaye olu phawu lwesakhiwo luphucula kakhulu ukusebenza kwezinto. Emva kokuba annealing, isakhiwo metallographic ofUmbhobho wentsimbi omnyamai-ferrite kunye nenani elincinci le-pearlite, kunye neempawu zoomatshini zilungile.

Imbali yophuhliso lweUmbhobho wentsimbi weNsimbiizele yintsha kunye neempumelelo. Ngasekupheleni kweminyaka yoo-1980 nasekuqaleni kweminyaka yee-1990, ejongene nokuvalwa kweteknoloji yokuvelisa umbhobho wentsimbi yentsimbi yangaphandle ye-centrifugal kunye neemeko eziqatha zogunyaziso lwelungelo elilodwa lomenzi wechiza, i-2672nd Factory ye-China People's Liberation Army (umanduleli we-Xinxing Casting Pipe) wathatha ngesibindi umsebenzi wophando oluzimeleyo kunye nophuhliso. Ngo-1993, umbhobho wentsimbi wokuqala we-centrifugal e-China waqengqelwa ngempumelelo ngaphandle komgca wemveliso, ephawula ukuba ilizwe lam liphumelele umtsi ukusuka ekuqaleni kweli candelo, kwaye kwathatha iminyaka esibhozo kuphela ukugqiba inkqubo yophuhliso lweminyaka engama-40 yamazwe aseNtshona. Namhlanje, i-Xinxing Casting Pipe iye yaphuhliswa yaba yeyona inkulu kwaye inamandla kakhulu emhlabeni yokuvelisa umbhobho wentsimbi ye-centrifugal, kwaye ithathe inxaxheba ekuqulunqweni kwemigangatho yemibhobho yehlabathi, ngokuqhubekayo ikhuthaza uphuhliso loshishino lwe-ductile iron pipe.

Imibhobho ye-Iron eneDuctile ineentlobo ngeentlobo zeempawu zokuSebenza

1. Amandla aphezulu kunye nokuqina okuhle: Imibhobho yentsimbi edibeneyo inamandla aphezulu, kwaye amandla abo aphuculwe kakhulu xa kuthelekiswa nemibhobho yentsimbi eqhelekileyo. Ngenxa yokuba igraphite isasazwe kwimilo engqukuva, isiphumo sokuqhekeka kwi-matrix siyancitshiswa, nto leyo eyenza ukuba umbhobho ungaphuki xa uphantsi koxinzelelo olukhulu kunye neempembelelo. Kwangaxeshanye, ikwanabo nokuqina okuhle, inobude obungaphezulu kwe-10%, kwaye iyakwazi ukuziqhelanisa nokuthotywa komhlaba, intshukumo yomhlaba kunye nezinye iimeko ukuya kumlinganiselo othile. Akulula ukuba konakaliswe yi-deformation, ephucula ukuthembeka komsebenzi womnatha wombhobho

2. Ukuxhathisa okuqinileyo kwe-Corrosion: Ngeendlela ezahlukeneyo zonyango lwe-anti-corrosion, ezifana nepeyinti yepeyinti ye-asphalt, i-sement mortar lining, i-epoxy coal tar coating, i-epoxy ceramic lining, i-aluminate cement coating, i-sulfate cement coating kunye ne-polyurethane, imibhobho ye-iron ductile inokumelana ngokufanelekileyo ne-corrosion evela kwimidiya eyahlukeneyo. Ingaba isetyenziselwa ukuthutha igesi, amanzi ompompo, okanye ukukhutshwa kwamanzi amdaka, inokugcina ukusebenza okuzinzile kwiindawo ezahlukeneyo eziyinkimbinkimbi, ukwandisa ubomi benkonzo yombhobho, kunye nokunciphisa iindleko zokulondoloza.
3. Ukutywinwa Okulungileyo: Umlomo wombhobho uthatha i-interface eguquguqukayo, enokuthi ilungelelanise ukufuduka kunye nokuguqulwa ngaphakathi koluhlu oluthile, yenza umphumo wokutywina kakuhle kwindawo yokudibanisa umbhobho, kunye nokuthintela ngokufanelekileyo ukuvuza kwamanzi. Ngelo xesha, inkqubo yokuvelisa i-high-precision yokwenziwa kombhobho ngokwayo iqinisekisa ukuchaneka kokuchaneka kwe-socket, iphucula ngakumbi ukusebenza kokutywinwa, kwaye iqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yombhobho.
4. Ufakelo olulula: Xa kuthelekiswa neminye imibhobho, ubunzima bemibhobho yentsimbi ye-ductile buphakathi, kwaye inkqubo yokufakela ilula. I-interface yayo eguquguqukayo iququzelela abasebenzi bokwakha ukuba baqhube umsebenzi wokudibanisa, ukunciphisa ixesha lofakelo kunye nokuqina kwabasebenzi. Kwindawo yokwakha, ukufakwa kwemibhobho kunokugqitywa ngokukhawuleza ngaphandle kwezixhobo ezinzima kunye neengcali zeengcali, ezinciphisa kakhulu umjikelezo weprojekthi kunye nokuphucula ukusebenza kakuhle kokwakhiwa.
5. Ukusebenza kakuhle kweAntifreeze: Kwiindawo ezibandayo, ukusebenza kwe-antifreeze kwimibhobho kubalulekile. Imibhobho yentsimbi enomlinganiselo othile wokunqanda umkhenkce. Logama nje ingeyiyo imeko-bume erhabaxa kakhulu, akusayi kubakho zintanda kunye nokugqabhuka komkhenkce. Oku kwenza ukuba isetyenziswe ngokubanzi kunikezelo lwamanzi, ukufudumeza kunye nezinye iinkqubo zemibhobho kwiindawo ezibandayo ezisemantla, ukubonelela ngeenkonzo ezithembekileyo kubahlali kunye namashishini.

Umbhobho waManzi we-Iron oxutyiweyoibe yimathiriyeli yombhobho eyimfuneko nebalulekileyo kulwakhiwo lweziseko zophuhliso lwangoku kunye neempawu zabo zokusebenza ezigqwesileyo. Ukusuka kunikezelo lwamanzi ezidolophini kunye nokuhanjiswa kwerhasi, ukusuka kwimveliso yemizi-mveliso ukuya kwiiprojekthi zolondolozo lwamanzi, imibhobho yentsimbi edonsa amanzi idlala indima ephambili kwiinkalo ezahlukeneyo kwaye ibe negalelo elibalulekileyo ekuqinisekiseni umgangatho wobomi babantu nokukhuthaza uphuhliso loqoqosho. Ngokuqhubela phambili okuqhubekayo kunye nokutsha kweteknoloji, ukusebenza kwemibhobho yentsimbi ye-ductile iya kuqhubeka nokuphucula, kwaye ububanzi besicelo buya kwandiswa ngakumbi. Ziya kuqhubeka nokuqaqamba kulwakhiwo lweziseko ezingundoqo kwixesha elizayo.
