High pressure resistant boiler chubu wopanga malo enieni
Machubu otenthetsera apakati komanso otsika ndi chitsulo chapamwamba kwambiri cha carbon structural steel chotenthetsera komanso chozizira (chogudubuzika) chosasokonekera chomwe chimagwiritsidwa ntchito popanga machubu otentha kwambiri, machubu ogudubuza amagetsi otsika komanso apakatikati azinthu zosiyanasiyana, machubu otentha kwambiri, machubu akulu a utsi. , machubu ang'onoang'ono a utsi ndi machubu a njerwa opangira ma boiler a locomotive. Amagwiritsidwa ntchito kwambiri pamapaipi omwe amanyamula madzi otsika komanso apakatikati pama boilers a mafakitale ndi ma boilers apanyumba. Zida zoyimira ndi 10 ndi 20 zitsulo.
Boiler chubu ndi mtundu wa chubu wopanda msoko. Njira yopangira ndi yofanana ndi chitoliro chosasunthika, koma pali zofunikira zokhwima pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo. Malinga ndi kutentha kwautumiki, amagawidwa mu chubu cha boiler wamba komanso chubu chopopera kwambiri.
The makina katundu wa boiler chubu ndi index yofunika kuonetsetsa ntchito yomaliza utumiki (makina katundu) wa zitsulo, zomwe zimadalira mankhwala zikuchokera ndi kutentha mankhwala dongosolo zitsulo. Muyeso wachitsulo chachitsulo, malinga ndi zofunikira zosiyanasiyana zautumiki, katundu wothamanga (mphamvu yothamanga, mphamvu zokolola kapena zokolola, elongation), zizindikiro zolimba ndi zolimba, komanso kutentha kwakukulu ndi kutsika komwe kumafunidwa ndi ogwiritsa ntchito kumatchulidwa.
① Nthawi zambiri, kutentha kwa ntchito yamachubu otenthetsera kumakhala pansi pa 350 ℃, ndipo machubu apakhomo amapangidwa makamaka ndi No. 10 ndi No.
②Machubu a boiler othamanga nthawi zambiri amakhala ndi kutentha kwambiri komanso kupanikizika kwambiri. Machubu adzakhala oxidized ndi dzimbiri pansi pa zochita za mkulu kutentha chitoliro mpweya ndi nthunzi. Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zokhalitsa, anti-oxidation yapamwamba ndi ntchito ya dzimbiri komanso kukhazikika kwadongosolo.
① Machubu a boiler ophatikizika amagwiritsidwa ntchito makamaka popanga machubu a khoma lamadzi, machubu amadzi otentha, machubu a nthunzi otentha kwambiri, machubu a nthunzi otentha kwambiri a ma boiler a locomotive, machubu akulu ndi ang'onoang'ono a utsi ndi machubu a njerwa.
②Machubu opopera oponderezedwa kwambiri amagwiritsidwa ntchito makamaka popanga machubu otenthetsera, machubu otenthetsera, machubu a mpweya, machubu akulu a nthunzi, ndi zina zambiri zama boiler othamanga kwambiri komanso othamanga kwambiri. Kapangidwe kake ndi kagwiritsidwe ntchito ka makina opangira ma boiler opanikizika kwambiri nthawi zambiri amakhala okhazikika, koma kupezeka ndi kufunikira kwamakampani ang'onoang'ono aliwonse kumasiyanitsidwa. Oyang'anira adawonetsa kuti cholumikizira chofunikira kwambiri ndikugwiritsa ntchito ndikulimbikitsa zatsopano zopulumutsa mphamvu komanso kutchinjiriza matenthedwe 20g zida zachubu zapa boiler.
Zatsopano zopulumutsa mphamvu 20g zopangira ma chubu opopera zichubu zikuchulukirachulukira pang'onopang'ono pamsika, monga zokutira zobiriwira zoteteza chilengedwe, zinthu zopulumutsa mphamvu komanso zopulumutsa madzi, miyala yoteteza chilengedwe, chitetezo cha chilengedwe chakunja kwa simenti yotchinjiriza thovu, etc. Chiyembekezo cha zinthu zopulumutsa mphamvu komanso zoteteza chilengedwe pamsika waukulu wa 20g wothamanga kwambiri wamachubu akulonjeza[1]
(1)GB / t5310-2008 machubu achitsulo opanda msoko a ma boilers othamanga kwambiri. Njira yoyezetsa mankhwala iyenera kukhala molingana ndi magawo ofunikira mu gb222-84, njira zowunikira mankhwala achitsulo, chitsulo ndi aloyi ndi njira za gb223 zowunikira chitsulo, chitsulo ndi aloyi.
(2) Zomwe zimapangidwa ndi mapaipi azitsulo za boilers zomwe zimatumizidwa kunja ziyenera kuyang'aniridwa molingana ndi mfundo zomwe zafotokozedwa mu mgwirizano.
