Amabhawodi anomumo we-U ayizingxenye ezingezona ezejwayelekile ezivame ukusetshenziselwa ukulungisa amapayipi afana namapayipi amanzi noma iziphethu zamaphepha ezifana neziphethu zamaqabunga ezimoto. Ngenxa yesimo sayo esinomumo we-U, ingahlanganiswa namantongomane, ngakho-ke yaziwa nangokuthi amabhawodi anomumo we-U noma amabhawodi okugibela.
Izimo eziyinhloko zamabhothi anomumo ongu-U zifaka phakathi i-semicircle, i-engeli yesikwele yesokudla, unxantathu, unxantathu oqondile njalo njalo. Amabhothi anomumo ongu-U anezici zezinto zokwakha ezahlukene, ubude, ububanzi kanye namazinga amandla angakhethwa ngokuya ngezimo zokusetshenziswa ezahlukene kanye nezidingo.
Unezinhlobonhlobo zokusetshenziswa, ezisetshenziswa kakhulu ekwakheni nasekufakeni, ekuxhumaneni kwezingxenye zemishini, ezimotweni nasemikhumbini, emabhuloho, emihubheni, ezitimeleni nakwezinye izindawo. Emalorini, ama-U-bolt asetshenziswa ukuqinisa indawo yemoto kanye nohlaka. Isibonelo, isiphethu samaqabunga sixhunywe ngamabhawodi anomumo we-U.
Ukukhetha ibanga le-bolt.
Amabanga ebholidi avame ukuhlukaniswa abe izinhlobo ezimbili: amabholidi anamandla aphezulu namabholidi ajwayelekile. Uma ukhetha ibanga lebholidi, kudingeka licatshangelwe ngokuya ngendawo yokusetshenziswa, izici zamandla, izinto zokusetshenziswa njalo njalo.
1. Ngokombono wezinto zokusetshenziswa: amabhawodi anamandla aphezulu enziwe ngezinto ezinamandla aphezulu, njengensimbi engu-45 #, insimbi engu-40 boron, insimbi engu-20 manganese titanium boron. Amabhawodi ajwayelekile avame ukwenziwa ngensimbi ye-Q235.
ezimbili.. Ngokuphathelene nezinga lamandla, amabhawodi anamandla aphezulu asetshenziswa kakhulu angama-8.8s nama-10.9s, lapho ama-10.9S esetshenziswa kakhulu. Ama-grade amandla amabhawodi avamile angama-4.4, 4.8, 5.6 kanye nama-8.8.
3. Ngokombono wezimpawu zomshini: amabhawodi anamandla aphezulu asebenzisa ukucindezela kwangaphambi kokucindezela futhi adlulise amandla angaphandle ngokungqubuzana. Ngakolunye uhlangothi, uxhumano olujwayelekile lwebhawodi luncike ekumelaneni kokugunda kwenduku yebhawodi kanye nokucindezela odongeni lwembobo ukuze kudluliselwe amandla okugunda, futhi ukucindezela kwangaphambi kokucindezela kuncane kakhulu lapho kuqinisa i-nut. Ngakho-ke, izici zomshini zidinga ukucatshangelwa ekusetshenzisweni.
4. Ngokombono wokusetshenziswa: uxhumano olunamabholidi lwezingxenye eziyinhloko zesakhiwo sesakhiwo luvame ukuxhunywa ngamabholidi anamandla aphezulu. Amabholidi ajwayelekile angasetshenziswa kabusha, kanti amabholidi anamandla aphezulu awakwazi ukusetshenziswa futhi ngokuvamile asetshenziselwa uxhumano oluhlala njalo.
Ngamafuphi, lapho sikhetha imininingwane kanye nezinga lebhawodi lebhawodi elinomumo we-U, kufanele sicabangele izinto zokwakha, izinga lamandla kanye nezici zokucindezeleka zebhawodi ngokuya ngesidingo sangempela kanye nendawo yokusetshenziswa, bese sikhetha umkhiqizo ofanele ukufeza umphumela wokuphepha, ukuzinza kanye nokuthembeka.
