Masiqale siqonde isifinyezo serediyasi ende kanye nerediyasi emfushane.
I-radius okukhulunywe ngayo lapha ibhekisela endaweni egobayo yendololwane yensimbi engagqwali.Indololwane yerediyasi ende ibhekisela endaweni yayo yokugoba elingana nobubanzi obuphindwe izikhathi ezingu-1.5 kububanzi obungaphandle bepayipi, okungukuthi, R=1.5D. Indololwane ye-radius emfushane isho ukuthi i-radius yayo yokugoba ilingana nobubanzi obungaphandle bepayipi, okungukuthi, R=1D.
Amandololwane erediyasi amade yiwo asetshenziswa kakhulu. Amandololwane erediyasi emfushane asetshenziswa kuphela lapho ehlangabezana nezimo ezithile ezikhethekile, njengesikhala sokufakwa esinganele.
Ngokombono wokusebenza, izinga lokugqokwa kwezindololwane ezinobubanzi obude lingaphansi kwalelo lamandololwane erediyasi emfushane, amandla okugqwala nawo ancipha kakhulu, futhi ukumelana nakho kuncane, okungcono kakhulu kunezindololwane zamarediyasi amafushane. Lapho ingcindezi iphezulu noma izinga lokugeleza liphezulu, kuzosetshenziswa izindololwane ezisuka emithanjeni emide. Uma izidingo zokumelana nepayipi elidlulisayo eliqinile ziqinile, kuzosetshenziswa indololwane enkulu engaba yi-radius. Ama-radius amafushane ngokuvamile asetshenziswa oketshezini olunomfutho ophansi noma lapho kunemikhawulo ekufakweni kwendololwane.
Amazinga ahlukene wokusebenzisa
Indololwane yensimbi engenasici ende: GB/T12459-2017; I-GB/T13401-2005; I-GB/T10752-1995; HGJ514-87; DL/T695-1999; I-D-GD87-0219.
Indololwane yensimbi engenasici emfushane: GB/T12459-2017; I-GB/T13401-2017; I-GB/T10752-1995; SH3408-1996; SH3409-1996.
Ubude besikhungo obuhlukene
Ifomula yokubala yobude obumaphakathi bendololwane yensimbi engagqwali:ububanzi * multiple Isibonelo, ububanzi obuhambisanayo obufanayo bobubanzi obungaphandle obungu-219mm bungama-200, bese ukuphakama okumaphakathi kwendololwane yensimbi engenasici ende ehambisanayo kungu-200*1.524=304.8, thatha 305;
Ukuphakama okumaphakathi kwendololwane yensimbi engenasici yerediyasi emfushane ngu-200*1.015=203
Ubukhulu obuthile obunemininingwane bezindololwane zensimbi engagqwali bungabukwa ngokuchofoza lapha.
