Chiyambi choyambirira cha mapaipi achitsulo opopera kwambiri

Mapaipi achitsulo otenthetsera kwambiri: omwe amagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon, alloy structural zitsulo, ndi mapaipi achitsulo osatentha osagwira kutentha kwa mapaipi opopera a nthunzi oponderezedwa kwambiri ndi kupitilira apo.Mapaipi a boiler awa amapangidwa kuti azigwira ntchito pansi pa kutentha kwambiri komanso kupanikizika., mapaipi adzalowanso ndi okosijeni ndi dzimbiri pansi pa mphamvu ya mpweya wotentha kwambiri wa flue ndi nthunzi wamadzi.Chifukwa chake, mapaipi achitsulo amafunikira kuti akhale ndi mphamvu zokhalitsa, kukana kwa okosijeni, komanso kukhazikika kwadongosolo.Makalasi achitsulo omwe amagwiritsidwa ntchito ndi awa: apamwamba kwambiri a carbon Structural steel grade ndi 20G, 20MnG, 25MnG;aloyi structural zitsulo makalasi ndi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.;Chitsulo chadzimbiri komanso chosagwira kutentha chomwe chimagwiritsidwa ntchito 1Cr18Ni9, 1Cr18Ni11Nb machubu opopera kwambiri amatsimikizira kapangidwe ka mankhwala ndi makina.Kuphatikiza apo, kuyezetsa kuthamanga kwa ma hydraulic kuyenera kuchitidwa m'modzim'modzi, ndikuyesa kukulitsa ndi kuwongolera kuyenera kuchitidwa.Mapaipi achitsulo amaperekedwa mumikhalidwe yotenthedwa.Kuphatikiza apo, palinso zofunika zina za microstructure, kukula kwambewu, ndi decarburization wosanjikiza wa chitoliro chomalizidwa chachitsulo.Mipope yachitsulo yopanda msoko pobowola geological ndi kuwongolera pobowola mafuta;zitsulo zobowolera zimagwiritsidwa ntchito pobowola zitsime pofufuza miyala ya pansi pa nthaka, madzi apansi panthaka, mafuta, gasi, ndi mchere.Kugwiritsa ntchito mafuta ndi gasi sikungasiyanitsidwe ndi kubowola zitsime.Mipope yachitsulo yopanda phokoso pobowola mafuta powongolera pobowola ndi zida zazikulu zobowola, makamaka kuphatikiza mapaipi akunja apakatikati, mapaipi amkati, mapaipi, mapaipi obowola, ndi zina zambiri. ntchito ndi zovuta kwambiri.Mapaipi obowola amakumana ndi zovuta monga kupsinjika, kupanikizika, kupindika, kugwedezeka, ndi katundu wosagwirizana, komanso kuvala matope ndi miyala.Chifukwa chake, mapaipi amafunikira kuti Ayenera kukhala ndi mphamvu zokwanira, kuuma, kukana kuvala, komanso kulimba kwamphamvu.Chitsulo chomwe chimagwiritsidwa ntchito popanga mapaipi achitsulo chimayimiridwa ndi "DZ" (chiyambi cha pinyin cha ku China cha geology) kuphatikiza nambala wani kuyimira malo opangira zitsulo.Nthawi zambiri amagwiritsidwa ntchito zitsulo monga DZ45 45MnB ndi 50Mn;DZ50's 40Mn2, 40Mn2Si;DZ55's 40Mn2Mo, 40MnVB;DZ60's 40MnMoB, DZ65's 27MnMoVB.Mapaipi achitsulo amaperekedwa mumikhalidwe yotenthedwa.Machubu osweka mafuta: Machubu opanda msoko a machubu a ng'anjo, machubu otenthetsera kutentha, ndi mapaipi opangira mafuta.Zomwe zimagwiritsidwa ntchito ndi zitsulo zamtengo wapatali za carbon (10, 20), alloy steel (12CrMo, 15CrMo), zitsulo zosagwira kutentha (12Cr2Mo, 15Cr5Mo), zitsulo zosapanga dzimbiri (1Cr18Ni9, 1Cr18Ni9Ti).Kuphatikiza pa kutsimikizira kapangidwe ka mankhwala ndi zida zosiyanasiyana zamapaipi achitsulo, mapaipi achitsulo amayeneranso kuwonetsetsa kuthamanga kwa madzi, kuwotcha, kuwotcha, ndi mayeso ena, komanso kuyesa kwapamwamba komanso kosawononga.Mapaipi achitsulo amaperekedwa mumikhalidwe yotenthedwa.Mapaipi achitsulo chosapanga dzimbiri: Mapaipi achitsulo osapanga dzimbiri otenthedwa ndi ozizira opangidwa ndi zitsulo zosapanga dzimbiri zosiyanasiyana amagwiritsidwa ntchito kwambiri pamapaipi amafuta ndi zida zamafuta ndi zida zachitsulo zosapanga dzimbiri pazifukwa zosiyanasiyana.Kuphatikiza pakuwonetsetsa kupangidwa kwamankhwala ndi makina amakina, chitoliro chilichonse chachitsulo chomwe chimagwiritsidwa ntchito polimbana ndi kuthamanga kwamadzimadzi ndichofunikira kuwonetsetsa kuti kuyesa kwa hydraulic pressure ndikoyenera.Mapaipi apadera apadera achitsulo ayenera kuonetsetsa kuti zinthu zili bwino malinga ndi malamulo.
