GB/T9948Chitoliro chachitsulo chosasunthika chophwanyira mafuta ndi chitoliro chosasunthika choyenera machubu a uvuni, zosinthira kutentha ndi mapaipi m'malo oyeretsera mafuta. Chitsulo chapamwamba cha kaboni, chitsulo chosungunuka ndi chitsulo chosapanga dzimbiri chosagwira kutentha mapaipi olimba osagwedezeka amagwiritsidwa ntchito popanga mapaipi a boiler a nthunzi okhala ndi mphamvu yokwera komanso yokwera. Mapaipi a boiler awa amagwira ntchito pansi pa kutentha kwakukulu ndi kupanikizika, ndipo mapaipiwo amakumana ndi utsi wotentha kwambiri. Kukhuthala ndi dzimbiri zidzachitikanso pansi pa mphamvu ya mpweya ndi nthunzi ya madzi. Chifukwa chake, mapaipi achitsulo amafunika kukhala ndi mphamvu yolimba kwambiri, kukana kukhuthala kwakukulu, komanso kukhazikika bwino kwa bungwe. Kuphatikiza pa kuonetsetsa kuti kapangidwe ka mankhwala ndi kagwiritsidwe ntchito ka makina, mapaipi a boiler okhala ndi mphamvu yokwera ayeneranso kuchita mayeso a kuthamanga kwa hydraulic amodzi ndi amodzi, kuphatikiza mayeso okulitsa ndi kupendeketsa. Mapaipi opanda mphamvu othamanga kwambiri amaperekedwa mu mkhalidwe wokonzedwa ndi kutentha.
Kupanga mapaipi osweka ndi kupanga mafuta:

① Nthawi zambiri, kutentha kwa ntchito ya mapaipi achitsulo chosasunthika kumakhala pansi pa 450°C. Mapaipi apakhomo amapangidwa makamaka ndi Nambala 10, Nambala 20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, mapaipi ozungulira otentha kapena mapaipi okokedwa ozizira.

② Mapaipi achitsulo okhazikika a GB9948 nthawi zambiri amakhala ndi kutentha kwambiri komanso kuthamanga kwambiri akagwiritsidwa ntchito. Mapaipiwo amasungunuka ndi kuzizira chifukwa cha mpweya wotentha kwambiri komanso nthunzi yamadzi. Mapaipi achitsulo amafunika kukhala ndi mphamvu yolimba, kukana kutentha kwambiri ndi dzimbiri, komanso kukhazikika bwino kwa kapangidwe kake.

gwiritsani ntchito:

① Kawirikawiri, mapaipi achitsulo osapindika amagwiritsidwa ntchito makamaka popanga mapaipi amadzi, mapaipi amadzi otentha, mapaipi a nthunzi otentha kwambiri, mapaipi a nthunzi otentha kwambiri a ma boiler a locomotive, mapaipi akuluakulu ndi ang'onoang'ono a utsi ndi mapaipi a njerwa za arch, ndi zina zotero.

Chitoliro chachitsulo chopanda msoko cha ②GB9948 chimagwiritsidwa ntchito makamaka popanga machubu a superheater, machubu obwezeretsanso, machubu owongolera mpweya, machubu akuluakulu a nthunzi, ndi zina zotero. pa ma boiler okhala ndi mphamvu yamphamvu komanso yamphamvu kwambiri.

Mapaipi achitsulo osasinthika a GB9948 amagawidwa m'mapaipi a boiler wamba ndi mapaipi a boiler okhala ndi mphamvu yayikulu kutengera momwe amagwirira ntchito kutentha kwambiri. Kaya machubu a boiler wamba kapena machubu a boiler okhala ndi mphamvu yayikulu, amatha kugawidwa m'mapaipi achitsulo osiyanasiyana kutengera momwe amagwiritsidwira ntchito mosiyanasiyana.
Chitoliro chachitsulo chosasunthika cha GB/T9948, mainchesi akunja 10 ~ 426mm, makulidwe a khoma 1.5 ~ 26mm. Mainchesi akunja ndi makulidwe a khoma a machubu a nthunzi otentha kwambiri, machubu akuluakulu a utsi, machubu ang'onoang'ono a utsi ndi machubu a njerwa za arch omwe amagwiritsidwa ntchito mu ma boiler a locomotive afotokozedwa mwanjira ina.

Ubwino wa mawonekedwe: Palibe ming'alu, mapindidwe, mipukutu, ziphuphu, ming'alu ndi mizere ya tsitsi zomwe zimaloledwa mkati ndi kunja kwa mapaipi achitsulo. Zolakwika izi ziyenera kuchotsedwa kwathunthu. Kuzama koyeretsa sikuyenera kupitirira kusiyana kwa makulidwe a khoma, ndipo makulidwe enieni a khoma pamalo oyeretsera sikuyenera kuchepera makulidwe ocheperako ololedwa a khoma.
