Zosapanga dzimbiri valavu valavu zimayambitsa ndi njira Stainless zitsulo vavu ndi mpweya zitsulo vavu kusiyana

Zosapanga dzimbiri valavu valavu zimayambitsa ndi njira Stainless zitsulo vavu ndi mpweya zitsulo vavu kusiyana

Chimodzi, zifukwa za dzimbiri zazitsulo zosapanga dzimbiri
Kufufuza ngati valavu yosapanga dzimbiri imatha dzimbiri, mutha kuyika valavu yomweyo m'malo osiyanasiyana kuti mutsimikizire kufananitsa, kunena, ngati valavu yachitsulo chosapanga dzimbiri imayikidwa pamalo owuma, pakapita nthawi yayitali zabwino zokhazokha zatsopano, komanso zopanda dzimbiri, koma ngati valavu imayikidwa m'madzi a m'nyanja yomwe ili ndi mchere wambiri, si masiku ochepa omwe adzachita dzimbiri, Zingaoneke kuti kukana kwa dzimbiri ndi kukana dzimbiri kwa mavavu osapanga dzimbiri kumafunikanso kukhala ndi malire pogwiritsa ntchito chilengedwe. Kuonjezera apo, kuchokera ku makhalidwe a valavu yachitsulo chosapanga dzimbiri yokha, si dzimbiri chifukwa pali filimu ya chromium-rich oxide pamwamba kuti iteteze ma atomu akunja a okosijeni ndi tinthu tating'ono tomwe timayambitsa kuwonongeka kwa chinthucho. kotero kuti ali ndi makhalidwe a dzimbiri, koma pamene filimu kuonongeka ndi zinthu zachilengedwe, monga maatomu mpweya mu ayoni ufulu chitsulo, valavu zosapanga dzimbiri zidzatulutsa dzimbiri.
Pali zifukwa zambiri za kuwonongedwa kwa zosapanga dzimbiri zitsulo vavu pamwamba filimu, chifukwa dzimbiri, filimu ena ndi zitsulo zinthu particles kapena fumbi electrochemical anachita, pa nthawi yomweyo ndi lonyowa mpweya monga sing'anga, mapangidwe yaying'ono batire mkombero, kupanga zitsulo zosapanga dzimbiri pamwamba dzimbiri, akhoza kukhala zosapanga dzimbiri zitsulo pamwamba filimu mwachindunji anakumana ndi asidi, zamchere ndi zina zamadzimadzi dzimbiri, chifukwa dzimbiri, etc. kuyeretsa zinthu, sungani ma valve pamwamba paukhondo.
Awiri, zitsulo zosapanga dzimbiri valavu dzimbiri njira
Ndiye mumawonetsetsa bwanji kuti pamwamba pazitsulo nthawi zonse zimakhala zowala komanso zosawonongeka? Malingaliro a kampani Sanjing Valve Manufacturing Co., Ltd. Malingaliro a akatswiri ndi aukadaulo:
1. Ndikofunika kuyeretsa ndi kupukuta pamwamba pazitsulo zosapanga dzimbiri zokongoletsa kawirikawiri, kuchotsa zomata ndikuchotsa zinthu zakunja zomwe zimayambitsa kusinthidwa.
2. Dera la m'mphepete mwa nyanja liyenera kugwiritsa ntchito zitsulo zosapanga dzimbiri 316, zinthu 316 zimatha kukana dzimbiri lamadzi a m'nyanja.
3. Mapangidwe a mankhwala a machubu ena osapanga dzimbiri pamsika sangathe kukumana ndi miyezo yapadziko lonse, mpaka 304 zofunikira zakuthupi. Choncho, zidzachititsanso dzimbiri, zomwe zimafuna kuti wogwiritsa ntchitoyo asankhe mosamala kupanga mapangidwe a opanga olemekezeka ndi malo omangapo kuti ateteze kumangidwa kwa zikopa ndi zowonongeka zomwe zimamangiriridwa, zomangamanga zosapanga dzimbiri pansi pa filimuyi. Koma ndi kutambasuka kwa nthawi, yotsalira phala madzi mogwirizana ndi moyo utumiki wa filimuyo, pambuyo yomanga filimu ayenera kuchotsedwa pamene pamwamba kutsuka, ndi kugwiritsa ntchito zipangizo zosapanga dzimbiri zitsulo, ndi ambiri zitsulo kuyeretsa zipangizo anthu, kuti tisalole zitsulo zachitsulo zomata ziyenera kutsukidwa. Chisamaliro chiyenera kuperekedwa kuti mankhwala oyeretsa kwambiri a maginito ndi miyala asamakhumane ndi chitsulo chosapanga dzimbiri, ngati akuyenera kutsukidwa nthawi yomweyo. Pambuyo pomanga, zotsukira zopanda ndale ndi madzi ziyenera kugwiritsidwa ntchito kutsuka simenti, ufa ndi phulusa pamwamba.
Zosapanga dzimbiri valavu ndi mpweya zitsulo valavu kusiyana zosapanga dzimbiri valavu ndi mpweya zitsulo valavu zinthu zinthu: The zipangizo ambiri mavavu zosapanga dzimbiri zitsulo ndi CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), 321, 1CR18NI9TI, 0CR18NI9, 310S, 2250 ndi 201 ndi zina wamba sanali muyezo zosapanga dzimbiri zipangizo. CF8, CF3, CF8M, CF3M ndi kalata zipangizo kuponyera kachidindo, 304,316 ndi mafomu ena digito chizindikiro ngati kupanga kachidindo mawonekedwe.
Vavu yachitsulo chosapanga dzimbiri ndi kusiyana kwa valavu ya carbon steel
Zinthu zosiyanasiyana:
The zipangizo ambiri mavavu zosapanga dzimbiri ndi CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), 321, 1CR18NI9TI, 0CR18NI9, 310S, 2250 ndi 201 ndi zina wamba sanali muyezo zosapanga dzimbiri zipangizo. CF8, CF3, CF8M, CF3M ndi kalata zipangizo kuponyera kachidindo, 304,316 ndi mafomu ena digito chizindikiro ngati kupanga kachidindo mawonekedwe. Ndipo CF8 (304) wamba American muyezo code, ndi lolingana kunyumba code ndi 0CR18NI9. Ndipo zofanana zapakhomo ndi 321 ndi 1CR18NI9TI. 304 nthawi zambiri imakhala ndi C≤0.08, Mn≤2.00, P≤0.045, S≤0.030, Si≤1.00, CR18.0-20.0, Ni:8.0-11.0.316 zinthu zakuthupi: C: 0.08 ~ 0. 1.0, Mn: ≤2.0, Cr: 16.18.0, S: ≤0.03,P: ≤0.045, Mo≤2.0-3.0, mogwirizana ndi muyezo wadziko lonse 0Cr17Ni12Mo2. 321 chitsulo chosapanga dzimbiri chili ndi zinthu zotsatirazi: kaboni C: ≤0.08; Si: ≤1.00, manganese Mn: ≤2.00, sulfure S: ≤0.030, P: ≤0.035, Cr: 17.00 ~ 19.00, Ni: 9.00 ~ 12.00, Ti: ≥5×C%. Ndipo 316L idakhazikitsidwa ndi kuwonjezera kwa nickel 316, imakhala ndi kukana kwa dzimbiri. Mtundu wofananira wa 310S ndi 2520 (0CR25NI20)). Nthawi zambiri timachitcha zitsulo ziwiri, zomwe ndi zitsulo zosapanga dzimbiri zokhala ndi kutentha kwapamwamba kwambiri komanso kukana kwa dzimbiri, ndipo mtengo wake ndi wokwera mtengo kwambiri. Kapangidwe ka mankhwala: C :≤0.08, Si :≤1.00, Mn :≤2.00, P :≤0.035, S :≤0.030, Ni :≤19.00-22.00, Cr :≤24.00-26.0. Vavu yachitsulo chosapanga dzimbiri ndi zitsulo zosapanga dzimbiri zimagwiritsa ntchito ***, zomwe zimagwiritsidwa ntchito m'mafakitale amankhwala, mafakitale azakudya, zomera zamadzi, etc., zimakhala bwino kukana dzimbiri, kukana kuthamanga, kukana kutentha, kukana kuvala, ukhondo ndi zina, ndizofunikira kwambiri. mavavu mafakitale ndi boma ndi zipangizo.
Mpweya zitsulo zambiri zipangizo ndi mpweya zitsulo WCB kuponyedwa zitsulo, A105 anamanga zitsulo, 20 # zitsulo, LCB otsika kutentha zitsulo ndi zina zotero. Nthawi zambiri, WCB carbon steel imagwiritsidwa ntchito. Mavavu achitsulo a WCB amatenga gawo lalikulu pamoyo watsiku ndi tsiku kapena mapaipi a mafakitale, ndipo mlingo wake ndi wapamwamba. A105 imapangidwa ndi chitsulo chonyezimira, chomwe chili ndi zinthu zabwino zamakokedwe, kachulukidwe kwambiri, kuthamanga kwambiri komanso kukana kutentha kwambiri, ndipo ndi yoyenera mapaipi ang'onoang'ono. 20 # chitsulo nthawi zambiri chimagwiritsidwa ntchito pazinthu zowonjezera, nthawi zambiri ngati ndodo, nthawi zambiri ma bolts, mtedza ndi zina zotero. LCB ndi otsika kutentha mpweya zitsulo, ntchito mu otsika kutentha mipope, ozizira yosungirako mipope ndi zina zotero. Mankhwala opangidwa ndi zinthu za WCB ndi: C≤ 0.3Mn ≤ 1.0Si ≤ 0.6P ≤ 0.05S ≤ 0.06Ni: 0.5Cr: 0.4Mo :0.25; A105 zopangira zitsulo ndi zinthu zoponyera zinthu zidzakhala ndi zosiyana: C:≤ 0.35Si :≤ 0.35Mn: 0.6-1.05S :≤ 0.050P :≤0.040; LCB otsika kutentha mpweya zitsulo ≤0.30 ≤0.60 ≤1.0 zitsulo LC3(-101℃)≤0.15 3.0 ~ 4.0.
Vavu yachitsulo chosapanga dzimbiri ndi mawonekedwe a valavu ya carbon steel ndi magawo ogwiritsira ntchito:
Mavavu osapanga dzimbiri ndi abwino kugwiritsa ntchito mapaipi owononga komanso mapaipi a nthunzi. Amakhala ndi kukana kwa dzimbiri, kukana kutentha kwambiri komanso kuthamanga kwambiri. Nthawi zambiri amagwiritsidwa ntchito m'mapaipi owononga a zomera zamankhwala, ndi mapaipi amadzi apampopi kapena mafakitale azakudya. The mpweya zitsulo vavu alibe dzimbiri kukana, angagwiritsidwe ntchito nthunzi, mafuta, madzi ndi zina zikuwononga sing'anga chitoliro, ndi mtengo wa carbon zitsulo valavu ndi wotsika kwambiri kuposa mtengo zosapanga dzimbiri, kotero zambiri palibe dzimbiri nthunzi ndi mapaipi ena. amagwiritsidwa ntchito carbon steel, ndi mavavu zosapanga dzimbiri zosapanga dzimbiri ndi zipangizo zina.
