Umuvuduko mwinshi wa boiler tube kugurisha
(1) Ibihugu nyamukuru bitumiza mu mahanga ibyombo ni Ubuyapani n'Ubudage. Ibisobanuro byibicuruzwa bitumizwa mu mahanga ni 15914.2mm; 2734.0mm; 219.110.0mm; 41975mm; 406.460mm, nibindi nibisobanuro byibuze ni 31.84.5mm, kandi uburebure muri rusange ni 5 ~ 8m.
.
(3) Imiyoboro y'icyuma itumizwa mu Budage ni 34CrMo4 na 12CrMoV. Ubu bwoko bwicyuma gifite imikorere yubushyuhe bwo hejuru kandi bukoreshwa kenshi nkumuyoboro wibyuma kubushyuhe bwo hejuru.
(4) Hariho imiyoboro myinshi ivanze itumizwa mu Buyapani, ifite ibisobanuro 426.012mm 5 ~ 8m; 152.48.0mm12m; 89.110.0mm6m; 101.610.0mm12m; 114.38.0mm6m; 127.08.0mm9m, nibindi. Shyira mubikorwa inganda zubuyapani jisg3458, naho icyiciro cyicyuma ni stpa25. Ubu bwoko bwicyuma gikoreshwa cyane nko gushyigikira umuyoboro wa superalloy.
Ibyuma bya karubone byujuje ubuziranenge, kandi amanota yicyuma ni 20g, 20mng na 25mng; Kuvanga ibyuma byubaka 15mog, umuyoboro mwinshi.
20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, nibindi; Usibye kwemeza imiterere yimiti nubukanishi, 1Cr18Ni9 na 1cr18ni11nb imiyoboro yumuvuduko mwinshi ukunze gukoreshwa mubyuma bitarwanya ubushyuhe bugomba gukorerwa ibizamini bya hydrostatike, gutwika no gusibanganya umwe umwe. Imiyoboro y'icyuma igomba gutangwa muburyo butunganijwe.
Mubyongeyeho, haribisabwa bimwe na microstructure, ingano yintete hamwe na decarburisation yumuringoti urangiye. Umuyoboro w'icyuma udafite icyerekezo cyo gucukura geologiya no kugenzura peteroli; Mu rwego rwo gucukumbura imiterere yubutare bwubutaka, amazi yubutaka, peteroli, gaze gasanzwe nubutunzi bwamabuye y'agaciro, hakoreshwa ibyuma byo gucukura amariba.
Gukoresha peteroli na gaze ntaho bitandukaniye no gucukura. Umuyoboro w'icyuma udafite icyerekezo cyo kugenzura ubucukuzi bwa geologiya no gucukura peteroli ni ibikoresho by'ingenzi byo gucukura, cyane cyane harimo umuyoboro w'inyuma w'imbere, umuyoboro w'imbere w'imbere, ikariso, umuyoboro, n'ibindi.
Nkuko umuyoboro wogucukura ukeneye gukora mubwimbye bwa metero ibihumbi, imiterere yakazi iragoye cyane, umuyoboro wimyitozo ufite ingaruka ziterwa nimpagarara, kwikanyiza, kunama, torsion hamwe nuburemere bwingaruka zingana, kandi byambarwa nicyondo nigitare . Kubwibyo rero, umuyoboro ugomba kuba ufite imbaraga zihagije, gukomera, kwambara no guhangana ningaruka zikomeye, Ibyuma byumuyoboro wibyuma bigereranwa na "DZ" (Ubushinwa bwa Ginyoni Pinyin prefix) wongeyeho umubare ugereranya aho umusaruro wibyuma. Ibyiciro bisanzwe bikoreshwa mubyuma ni 45mnb na 50Mn ya dz45; 40Mn2 na 40mn2si ya dz50; 40mn2mo na 40mnvb ya dz55; 40mnmob ya DZ60 na 27mnmovb ya dz65.
Imiyoboro y'ibyuma itangwa muburyo bwo kuvura ubushyuhe.
Umuyoboro udafite umuyoboro w'itanura, umuyoboro uhindura ubushyuhe n'umuyoboro mu ruganda rwa peteroli. Ubusanzwe ikozwe mubyuma byo mu rwego rwo hejuru (10, 20), ibyuma bivanze (12CrMo, 15CrMo), ibyuma birwanya ubushyuhe (12cr2mo, 15cr5mo) hamwe nicyuma kitagira umwanda (1Cr18Ni9, 1Cr18Ni9Ti). Usibye imiterere yimiti nuburyo butandukanye bwubukanishi bwumuyoboro wibyuma, birakenewe kandi kwemeza hydrostatike, gusibanganya, gutwika nibindi bizamini, hamwe nubuziranenge bwubuso no kwipimisha bidafite ishingiro. Imiyoboro y'ibyuma igomba gutangwa hifashishijwe ubushyuhe.
Ubwoko bwose bw'ibyuma bidafite ingese bishyushye kandi bikonje bikonje bikoreshwa cyane mu miyoboro ya peteroli n'ibikoresho bya shimi hamwe n'ibice byubatswe bidafite ibyuma kubintu bitandukanye. Usibye kwemeza imiterere yimiti nubukanishi, imiyoboro yose yicyuma ikoreshwa mugutwara umuvuduko wamazi igomba kuba yujuje ibizamini bya hydrostatike. Imiyoboro inyuranye idasanzwe igomba kwemezwa hakurikijwe ibihe byagenwe.
Umuvuduko ukabije wumuyoboro wicyuma ni ubwoko bwumuyoboro udafite kashe. Uburyo bwo gukora ni bumwe nkubw'umuyoboro udafite kashe, ariko haribisabwa cyane kurwego rwicyuma gikoreshwa mugukora imiyoboro yicyuma. Ukurikije ubushyuhe bwa serivisi, igabanyijemo umuyoboro rusange wogukora hamwe nigitutu cyumuvuduko mwinshi.
① Ubushyuhe bwa serivisi bwumuvuduko ukabije wumuyoboro wicyuma uri munsi ya 450 and, kandi umuyoboro wimbere mu gihugu ugizwe ahanini na No 10 na No 20 ibyuma bya karubone bishyushye cyangwa umuyoboro ukonje.
②Umuvuduko ukabije wicyuma udafite icyuma akenshi kiri mubushyuhe bwinshi hamwe nubushyuhe bwo hejuru. Umuyoboro uzahinduka okiside kandi ugakororwa hifashishijwe gaze yubushyuhe bwo hejuru hamwe na parike. Umuyoboro w'icyuma urasabwa kugira imbaraga ndende zirambye, anti-okiside nyinshi hamwe no kwangirika no guhagarara neza.
① Umuvuduko ukabije wumuyoboro wicyuma ukoreshwa cyane cyane mugukora umuyoboro wamazi wamazi, umuyoboro wamazi utetse, umuyoboro wamazi ushushe, umuyoboro wamazi ushushe kumashanyarazi, imiyoboro minini nini ntoya hamwe numuyoboro wamatafari.
② Umuvuduko ukabije wicyuma udafite icyuma gikoreshwa cyane cyane mugukora umuyoboro wa superheater, umuyoboro wa reheater, umuyoboro wumwuka, umuyoboro wingenzi, nibindi byumuvuduko mwinshi hamwe nubushyuhe bukabije bwamashanyarazi mumashanyarazi.
