Amagwiritsidwa ntchito kuthamanga kwambiri min.Wall makulidwe opanda mpweya zitsulo Boiler ndi Superheater chubu
Magulu Akuluakulu a Chubu: A192
Machubu a boiler ndi machubu opanda msoko ndipo amapangidwa ndi chitsulo cha carbon kapena alloy steel.Amagwiritsidwa ntchito kwambiri m'ma boilers a nthunzi, kupanga magetsi, m'mafakitale opangira mafuta, mafakitale opangira mafakitale, magetsi opangira magetsi, ndi zina zotero.
Machubu a boiler nthawi zambiri amapangidwa m'njira zopanda msoko.Nayi tsatanetsatane wa momwe amapangidwira:
Kodi Machubu a Boiler Amapangidwa Bwanji?
Machubu onse apakati-pakatikati komanso othamanga kwambiri amapitilira njira yofananira yopangira, yomwe imaphatikizapo kujambula bwino, kowala pamwamba, kugudubuza kotentha, kukokedwa kuzizira komanso kukulitsa kutentha.Komabe, njira zotsatirazi zikuchitidwa kuti mapaipi amphamvu kwambiri akhale olimba komanso osamva.
Chithandizo cha kutentha chimaphatikizapo kutentha ndi kuziziritsa kwa mapaipi opopera opopera kwambiri omwe amawonjezera kulimba, kulimba komanso kukana kuvala.Masitepe osiyanasiyana omwe amabwera pansi pa chithandizo cha kutentha amaphatikizapo kuzimitsa, kutenthetsa ndi kutsekemera.
Kuzimitsa kumachitika kuti muwonjezere kuuma kwa chubu chopopera chopondera kwambiri.Chitolirocho chimatenthedwa mofanana mpaka kutentha koyenera ndiyeno kumizidwa mwamsanga m'madzi kapena mafuta kuti chizizire nthawi yomweyo.Izi zimatsatiridwa ndi kuziziritsa mumpweya kapena kumalo oziziritsa.
Kutentha kumagwiritsidwa ntchito kuchotsa brittleness mu chitoliro.Kuzimitsa kungapangitse kuti chitoliro chigwedezeke kapena kusweka.
Annealing akhoza kuchotsa kupsyinjika mkati mu chitoliro.Pochita izi, chubu chopanda msoko chimatenthedwa ndi kutentha kwakukulu ndikusiyidwa kuti chizizizira pang'onopang'ono muphulusa kapena laimu.
Kuchotsa Dzimbiri kwa Boiler Tube
Pali njira zingapo zochotsera dzimbiri mu chubu chowotchera, chosavuta ndikuyeretsa pogwiritsa ntchito zosungunulira ndi emulsion.Komabe, izi zimatha kuchotsa fumbi, mafuta, etc. koma sizingachotse chitoliro chonse pa zotsalira za organic.
Njira yachiwiri ndiyo kuchotsa dzimbiri pogwiritsa ntchito zida zamanja kapena zamagetsi.Kuyeretsa zida kumatha kuchotsa zokutira za oxide, kuwotcherera slag ndi dzimbiri.
Njira yodziwika kwambiri ndi njira zamankhwala ndi electrolytic, zomwe zimadziwikanso kuti kuyeretsa asidi.
Kuchotsa dzimbiri ndi kupopera mbewu mankhwalawa ndiyo njira yabwino kwambiri yoyeretsera chubu la boiler chifukwa imatha kuchotsa dothi, okusayidi ndi dzimbiri mpaka pamlingo waukulu.Kuphatikiza apo, imatha kukulitsa kuuma kwa chitoliro.
Momwe Mungasankhire Machubu Abwino Opangira Boiler?
Posankha machubu opopera, yang'anani zotsatirazi kuti musankhe machubu oyenera komanso abwino:
1. Yang'anani pamtanda wa chubu.Chubu chabwino chopanda msoko chidzakhala ndi gawo losalala komanso lopanda ma bampu ndi zolakwika.
2. Yang'anani kuchuluka kwa chitoliro kuti mumvetsetse kuchuluka kwa zonyansa mu chitoliro.Ngati chitoliro chikuwonetsa kuchulukira pang'ono, yambani bwino!
3. Onetsetsani kuti mwayang'ana chizindikiro.Opanga odziwika nthawi zonse amayika chizindikiro chawo pamachubu awo opanda msoko.
4. Yang'anani pamwamba pa chubu chowotchera.Chubu chabwino cha boiler chimakhala ndi malo osalala.Ngati mupeza kuti pamwamba pake ndi yovuta komanso yosagwirizana, mungakhale otsimikiza kuti khalidwelo silinafike polembapo.
