I-flanging eyindilingaokuhlangene okungezona ezensimbikanye nesikhumba esingesona insimbi esingunxande siwuhlobo lwesikhumba sendwangu engeyona eyensimbi. Uma kuqhathaniswa nesikhumba esihlangene sokwandisa i-hemming, ngesikhathi sokukhiqiza, indawo yokusebenzela idinga ukwenza amakhona ayindilinga noma ayizikwele ukuze kufakwe kalula ngokusho kwemidwebo. Inqubo yokukhiqiza iyinkimbinkimbi kakhulu. Isikhumba esingesona insimbi siwuhlobo olusha lwezinto ezishisayo zokushisa ezisezingeni eliphezulu ezakhiwe ngendwangu yengilazi yefayibha kanye nendwangu yengilazi ye-silica ehlanganiswe nengilazi yengilazi kanye nenye indwangu engashi kanye nokumelana nokushisa okuphezulu. Uma kuqhathaniswa nezinto zensimbi, ukusebenza okuphelele kwezinto ezingezona ezensimbi ezifana nokumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali kanye nokuzinza kwamakhemikhali kuye kwadlula kude lokho kwezinto zensimbi. Ububi bezikhumba zendwangu ezingewona ezensimbi eziguquguqukayo ukuthi azikwazi ukusetshenziswa ezindaweni ezinomfutho ophezulu. Ngokuvamile, ezindaweni ezingaphezu kuka-0.5mpa, kuyadingeka ukuthi ucabange ukusebenzisa amajoyinti okunweba ensimbi noma amajoyinti okunwetshwa kwerabha okungeyona eyensimbi esikhundleni salokho.
Ungawalinganisa kanjani amajoyinti okunwebeka angewona awensimbi?
1. Ama-flange bolts kufanele aqiniswe kancane kancane futhi afane, futhi ukuqina kwama-bolts kufanele kuhambisane ngangokunokwenzeka. Endabeni yezimo ezinzima, i-spring washer ebuthakathaka ingafakwa ngaphezu kwe-washer eyisicaba ukuze uvimbele i-nati ukuthi ingaxegi.
2. I-asbestos gasket yerabha ehambisanayo kufanele isetshenziswe kuqala ngokwezinga lokushisa elisebenzayo phakathi kwejoyinti lokunweba kanye ne-flange yokushisela ehambisanayo.
3. Ngesikhathi sokuhlolwa, isikulufu somkhawulo sejoyinti lokunweba kufanele silungiswe kahle ukuze kube lula ukunwetshwa noma ukuminyanisa komkhiqizo.
4. Uma ipayipi elishiselwe lixhunyiwe, isikulufu somkhawulo kufanele sithukululwe kahle ukuze kuvinjelwe ipuleti eliwumkhawulo lejoyinti lokunweba ukuthi lingagobi noma ukukhubazeka komkhiqizo.
5. Ngesikhathi sokusebenza kwe-welding, isetshenziswa njengesembozo sokumboza ubuso benjoloba (indwangu) ukuvimbela i-welding slag ekulimazeni umkhiqizo.
Siphinde sibe nakhoimigudu yomoya eguquguqukayo, ama-air ducts avaliwe!
