Chitoliro Chopanda Chitsulo Chopanda Chitsulo Choyendetsa Madzi
1. 321 chitoliro chachitsulo chosapanga dzimbiri.Chitoliro chachitsulo chosasunthika (GB14976-2002) chimagwiritsidwa ntchito popanga mapaipi otentha kwambiri, mapaipi amadzi otentha ndi mapaipi amoto otentha kwambiri, mapaipi akuluakulu a utsi, mapaipi ang'onoang'ono a utsi ndi mapaipi a njerwa amitundu yosiyanasiyana.Chitsulo chopangidwa ndi kaboni chotenthetsera komanso chokokedwa ndi kuzizira (chogudubuza) machubu achitsulo opanda msoko.
2. 321 mapaipi azitsulo zosapanga dzimbiri: zitsulo zamtengo wapatali za carbon structural steel, alloy structural zitsulo ndi mapaipi achitsulo osatentha osatentha osasunthika omwe amagwiritsidwa ntchito kwambiri popanga mapaipi opopera othamanga kwambiri komanso pamwamba pa nthunzi.Mapaipi a boiler awa nthawi zambiri amakhala ndi kutentha kwambiri komanso kuthamanga kwambiri.Ntchito ndi mapaipi nawonso adzakumana ndi makutidwe ndi okosijeni ndi dzimbiri chifukwa cha kutentha kwambiri kwa gasi wa flue ndi nthunzi wamadzi.Chifukwa chake, mapaipi achitsulo amafunikira kuti akhale ndi mphamvu zokhalitsa, kukana kwa okosijeni, komanso kukhazikika kwadongosolo.Mapaipi a hydraulic prop.
3. Makalasi azitsulo omwe amagwiritsidwa ntchito pa mapaipi a 321 osapanga dzimbiri ndi awa: 304 321 316 317 310, etc.
4. Aloyi structural zitsulo chitoliro zitsulo makalasi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.;pali zitsulo zosapanga dzimbiri zosagwira kutentha zomwe zimagwiritsidwa ntchito 1Cr18Ni9, 1Cr18Ni11Nb machubu othamanga kwambiri, kuwonjezera pakuwonetsetsa kuti mankhwala amapangidwa ndi makina, kuthamanga kwamadzi kuyenera kuchitidwa imodzi ndi imodzi.Kuti muyesedwe, kuyezetsa kowotcha ndi kusalala kuyenera kuchitidwa.
5. 321 mapaipi azitsulo zosapanga dzimbiri amaperekedwa mumkhalidwe wotentha.Kuphatikiza apo, palinso zofunika zina za microstructure, kukula kwa tirigu, ndi wosanjikiza decarburized wa chitoliro yomalizidwa zitsulo.Mipope yachitsulo yopanda msoko pobowola geological ndi kuwongolera pobowola mafuta;gwiritsani ntchito zida zobowola pobowola zitsime pofufuza momwe miyala yapansi panthaka, madzi apansi panthaka, mafuta, gasi ndi mchere amagwirira ntchito.Kufufuza kwa petroleum ndi gasi ndikosiyana kwambiri ndi kukumba zitsime.Mipope yachitsulo yopanda msoko pobowola ndi kuyang'anira geological ndi zida zazikulu pobowola, kuphatikiza machubu apakatikati, machubu amkati, ma casings, ndi mapaipi oboola.Chifukwa chitoliro chobowola chiyenera kukhala chakuya pakuzama kwa makilomita angapo kuti chigwire ntchito, chitoliro cha aloyi 1cr5mo.
6. Mikhalidwe yogwirira ntchito ndi yovuta kwambiri.Chitoliro chobowola chimakhala ndi zovuta monga kupsinjika, kupsinjika, kupindika, kugwedezeka, ndi kusuntha kosafanana, komanso kuvala matope ndi miyala.Choncho, chitoliro chiyenera kukhala ndi mphamvu zokwanira, kuuma, kuvala kukana ndi kuuma kwa Impact, chitoliro chachitsulo chogwiritsidwa ntchito "DZ" (Geological Pinyin prefix) kuphatikizapo nambala imodzi kuti iwonetsere zokolola zazitsulo, zomwe zimagwiritsidwa ntchito nthawi zambiri zitsulo ndi 45MnB, 50Mn DZ45;DZ50 40Mn2, 40Mn2Si;DZ55 40Mn2Mo, 40MnVB;40MnMoB ya DZ60, 27MnMoVB ya DZ65.Mipope yachitsulo imaperekedwa mumkhalidwe wotentha.
7. Mapaipi osweka mafuta: mapaipi opanda msoko a mapaipi ang'anjo, mapaipi otenthetsera kutentha ndi mapaipi omwe amagwiritsidwa ntchito poyenga mafuta.Zomwe zimagwiritsidwa ntchito kwambiri za carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), zitsulo zosagwira kutentha (12Cr2Mo, 15Cr5Mo), zitsulo zosapanga dzimbiri (1Cr18Ni9, 1Cr18Ni9Ti) kupanga.
8. Mipope yachitsulo yosasunthika ya mapaipi 321 osapanga dzimbiri (GB3087-1999) amagwiritsidwa ntchito popanga mapaipi otentha kwambiri, mipope yamadzi otentha ndi mapaipi amoto otentha kwambiri, mapaipi akuluakulu a utsi, mapaipi ang'onoang'ono a utsi ndi mipope ya njerwa yamitundu yosiyanasiyana. ma boilers apakati.Chitsulo chapamwamba cha carbon structural chotenthetsera komanso chozizira (chogudubuzika) chosasokonekera.Chitoliro chachitsulo chosapanga dzimbiri cha 321: Chimagwiritsidwa ntchito makamaka popanga zitsulo zapamwamba kwambiri za carbon, alloy structural chitsulo ndi zitsulo zosapanga dzimbiri zosagwira kutentha zitsulo zosapanga dzimbiri zamapaipi opopera a nthunzi zoponderezedwa kwambiri ndi pamwamba.Mapaipi a boiler awa amagwira ntchito pansi pa kutentha kwambiri komanso kuthamanga kwambiri., The chitoliro adzakhala oxidized ndi dzimbiri pansi zochita za mkulu kutentha chitoliro mpweya ndi nthunzi madzi.Chifukwa chake, chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu yayitali kwambiri, kukana kwa okosijeni, komanso kukhazikika kwadongosolo, chitoliro cha hydraulic prop.
9. 321 mapaipi azitsulo zosapanga dzimbiri amaperekedwa mumkhalidwe wotentha.Kuphatikiza apo, palinso zofunika zina za microstructure, kukula kwa tirigu, ndi wosanjikiza decarburized wa chitoliro yomalizidwa zitsulo.Mipope yachitsulo yopanda msoko pobowola geological ndi kuwongolera pobowola mafuta;gwiritsani ntchito zida zobowola pobowola zitsime pofufuza momwe miyala yapansi panthaka, madzi apansi panthaka, mafuta, gasi ndi mchere amagwirira ntchito.
