1, Ibiranga n'ibigize imiti
Urwego hamwe na chimique yibyuma byumuyoboro wibyuma bigomba kuba byujuje ibyiciro hamwe nubumara bwibikoresho byicyuma kumiyoboro yumukara nkuko bigaragara muri GB / T3091.
2, Uburyo bwo gukora
Uburyo bwo gukora umuyoboro wumukara (gusudira itanura cyangwa gusudira amashanyarazi) byatoranijwe nuwabikoze.Gushyushya-dip galvanizing ikoreshwa mugusunika.
3. Urudodo hamwe nuyoboro
.Urudodo rugomba kubahiriza amabwiriza ya YB 822.
(b) Guhuza imiyoboro y'icyuma igomba kubahiriza YB 238;guhuza ibyuma byoroshye guhuza ibyuma bigomba kubahiriza YB 230.
4. Ibikoresho bya mashini Ibikoresho bya mashini yimiyoboro yicyuma mbere yo gusya bigomba kuba byujuje ibisabwa GB 3091.
5. Uburinganire bwurwego rwa galvanised Umuyoboro wibyuma ugomba kugeragezwa kugirango uburinganire bwurwego.Icyitegererezo cy'icyuma ntigishobora guhinduka umutuku (ushyizweho umuringa) nyuma yo kwibizwa mumuti wa sulfate y'umuringa inshuro 5 zikurikiranye.
6, Cold bend test test galvanized pipe umuyoboro ufite diameter nominal itarenze 50mm igomba kuba ikizamini gikonje.Inguni yunamye ni 90 °, naho radiyo yunamye ikubye inshuro 8 z'umurambararo.Nta wuzuza mugihe cyizamini, kandi gusudira kwicyitegererezo bigomba gushyirwa hanze cyangwa igice cyo hejuru cyerekezo cyunamye.Nyuma yikizamini, ntihakagombye kubaho gucamo no gukuramo ibice bya zinc kuri sample.
7, Ikizamini cyumuvuduko wamazi Ikizamini cyumuvuduko wamazi kigomba gukorerwa muri Clarinet, kandi ikizamini cya eddy nacyo gishobora gukoreshwa aho kugerageza umuvuduko wamazi.Umuvuduko wikizamini cyangwa ingano yikigereranyo cyo kugereranya eddy igezweho igomba kuba yujuje ibisabwa GB 3092. Imiterere yubukanishi bwibyuma nibimenyetso byingenzi kugirango ikoreshwe bwa nyuma (ibikoresho bya mashini) byuma.
Imbaraga zikomeye (σb):Imbaraga ntarengwa (Fb) icyitegererezo gitwara iyo kimenetse mugihe cyo kurambura, kugabanwa na stress (σ) yabonetse mukugabanya igice cyambere cyambukiranya igice (So) cyicyitegererezo, cyitwa resistance Tensile strength (σb) , igice ni N / mm2 (MPa).Yerekana ubushobozi ntarengwa bwibikoresho byicyuma cyo kurwanya ibyangiritse ku mbaraga zikomeye.Muri formula: Fb-imbaraga ntarengwa icyitegererezo gitwara iyo kimenetse, N (Newton);Noneho-umwimerere wambukiranya igice cyicyitegererezo, mm2.
Ingingo Yerekana (σs):Kubikoresho byicyuma hamwe numusaruro utanga umusaruro, guhangayikishwa nicyitegererezo gishobora gukomeza kuramba bitongereye imbaraga mugihe cyo kurambura byitwa umusaruro.Niba imbaraga zigabanutse, ingingo zo hejuru nu munsi zo gutanga umusaruro zigomba gutandukanywa.Igice cy'umusaruro ni N / mm2 (MPa).Hejuru Yumusaruro (σsu): Guhangayikishwa cyane mbere yuko urugero rutanga kandi imbaraga zigabanuka kunshuro yambere;Ingingo Yibanze Yumusaruro (σsl): Guhangayikishwa byibuze murwego rwo gutanga umusaruro mugihe ingaruka yambere yinzibacyuho ititaweho.Aho: Fs - gutanga imbaraga (guhoraho) mugihe cyurugero rwicyitegererezo, N (Newton) Rero - umwimerere wambukiranya igice cyicyitegererezo, mm2.
Kurambura nyuma yo kumena:.Byerekanwa na σ, igice ni%.Muri formula: L1-uburebure bwa gauge yikigereranyo nyuma yo kumena, muri mm;L0-uburebure bwa gipima uburebure bwikigereranyo, muri mm.
Kugabanya agace:.Byerekanwe muri ψ, igice ni%.Muri formula: S0-umwimerere wambukiranya igice cyicyitegererezo, mm2;S1-byibuze byibuze byambukiranya igice kuri diameter yagabanutse ya sample nyuma yo kumeneka, mm2.
Index Icyerekezo gikomeye:Ubushobozi bwibikoresho byibyuma byo kurwanya indentation yibintu bikomeye hejuru byitwa gukomera.Ukurikije uburyo butandukanye bwikizamini hamwe nuburyo bukoreshwa, ubukana burashobora kugabanywa mubukomere bwa Brinell, gukomera kwa Rockwell, gukomera kwa Vickers, gukomera kwa Shore, ubukana bwa micro hamwe nubushyuhe bukabije.Hariho imiyoboro itatu ikunze gukoreshwa: Brinell, Rockwell, na Vickers gukomera.
Gukomera kwa Brinell (HB):Koresha umupira wibyuma cyangwa umupira wa karbide wa sima hamwe na diameter runaka kugirango ukande hejuru yicyitegererezo hamwe nimbaraga zipimishije (F), ukureho imbaraga zipimisha nyuma yigihe cyagenwe cyo gufata, hanyuma upime diameter ya indentation hejuru yubuso icyitegererezo (L).Agaciro gakomeye ka Brinell nigipimo cyabonetse mugabanye imbaraga zipimisha nubuso bwubuso bwa indentation.Byerekanwe muri HBS (umupira wibyuma), igice ni N / mm2 (MPa).
