U - impeta yimanitse yimanitse ikozwe mubyuma nkibikoresho fatizo, binyuze muburyo bunoze no gushimangira ubuvuzi. Imiterere igabanijwemo gufunga - loop na kimwe cya kabiri - gifunze - ubwoko bwizunguruka. Mugihe cyo gukoresha, bafite ibiranga imiterere ihamye, guhuza n'imihindagurikire, kurwanya ibidukikije, hamwe n’umutekano muke. Nibyo, ibyo biranga ntibishobora gutandukana no guhitamo ibikoresho. Hasi, tuzamenyekanisha ibikoresho bisanzwe byatoranijwe mugihe cyo gukora.
Ibyuma bya karubone: Ibirimo bya karubone ni 0,12% - 0.45%, imbaraga zingana ni 400MPa - 600MPa, imbaraga zitanga umusaruro ni 235MPa-355MPa. Ubusanzwe ikoreshwa mukuzamura urwego ruciriritse. Ibyuma bya karubone bifite igiciro gito nimbaraga zo gukanika cyane, kubwibyo rero ni ibikoresho bihenze cyane mubicuruzwa byoherezwa mu mahanga, bingana na kimwe cya kabiri cy’ibicuruzwa byoherezwa mu mahanga.
Ibyuma bidafite ingese: Hariho ubwoko bwinshi bwibyuma, harimo 304, 316, na 316L. Urebye ibiciro, abakoresha mubisanzwe bahitamo ibyuma 304 bidafite ingese, birimo chromium 18% na nikel 8%, bifite imbaraga zingana Kurenza cyangwa bingana na 515MPa, birwanya ruswa ikomeye, kandi bikwiranye nibidukikije byangiza kandi byoroshye. Ibyoherezwa cyane cyane mu majyepfo y’amajyepfo ya Aziya no mu Burayi bw’imbere, ibyuma 316 bidafite ingese bishingiye kuri 304 hiyongereyeho molybdenum, biteza imbere kurwanya imiti y’umunyu hamwe na ruswa yangiza imiti irenga 50%. Irakwiriye gukoreshwa mu nyanja, ku nkombe, no mu miti kandi yoherezwa mu bihugu byo ku nkombe z’Uburayi, Amerika, Ositaraliya, n'Uburasirazuba bwo hagati.
Amavuta avanze: Ibiranga byongerewe imbaraga hamwe. Ifite imbaraga zingana kurenza cyangwa zingana na 800MPa, imbaraga z'umusaruro uruta cyangwa zingana na 650MPa, irwanya ubushyuhe bwo hejuru bwa dogere 40 kugeza kuri dogere 300, ifite umunaniro mwiza, kandi irashobora gukoreshwa mumitwaro ikabije.
Ikoreshwa rya U - rifite ibyuma bimanika impeta mu nganda zingufu ni ngombwa ku isi. Nkumuhuza hagati yumurongo wogukwirakwiza numuyoboro witumanaho, bakora imirimo itatu yingenzi: guhuza insulator, gukosora ibyuma byububiko, no guhagarika insinga. By'umwihariko mumurongo wo hejuru - umuyoboro wa voltage, uburemere - impeta zo guterura imisoro, zikoreshwa zifatanije numugozi wa insulator hamwe niminara, byorohereza imiyoboro yabatwara. Hamwe nuburemere bwa 69kN-200kN, bagomba kubahiriza amahame mpuzamahanga akwiranye n’amashanyarazi nka IEC 61466 na GB 2314. Nyuma yo kubahiriza ibipimo byoherezwa mu mahanga mu bihugu bitandukanye, birashobora gukoreshwa cyane.
Ku bakiriya b’ubucuruzi bw’amahanga cyangwa abakoresha bakoresha U - bikozwe mu mpapuro zimanikwa ku nshuro ya mbere, bahangayikishijwe cyane no kubitaho no kubitaho mu gihe kirekire -. Niba igihe cyibicuruzwa gishobora kongerwa binyuze mukubungabunga no kubitaho, bigabanya ikiguzi cyishoramari, byaba byiza cyane.
Gucunga imizigo
Umutwaro nikintu cyingenzi mugihe cyo gukoresha. Abakoresha benshi bibaza niba umutwaro uzahinduka nkuko tubikoresha. Mubyukuri, tugomba kwirinda kurenza urugero mugihe cyo gukoresha. Kurenza urugero birashobora kuganisha kumiterere ya plastike no kuvunika, cyane cyane iyo ibice bihujwe murukurikirane. Tugomba kwemeza ko umutwaro ugabanijwe neza.
Kugenzura buri gihe
Igenzura ryonyine rishobora kumenya ibibazo. Mugihe kirekire - gukoresha manda, birasabwa kugenzura buri mezi 3. Ubugenzuzi bugomba kubamo niba umubiri wingenzi wahinduwe cyangwa wacitse, kandi niba ibipapuro na bolts birekuye cyangwa byangiritse. Ibice bidakabije bigomba gukomera mugihe, kandi ibice byahinduwe bigomba gusimburwa mugihe. Ntukayikoreshe niba itujuje ibisabwa.
Isuku no kuyitaho
Uburyo bwo gukora isuku biterwa nibidukikije. Kurugero, ahantu humye, ohanagura umukungugu wo hejuru hamwe nigitambara cyumye. Ntukoreshe umwenda utose cyangwa ibikoresho byoza. Kubidukikije byo mu nyanja, kwoza hejuru y'amazi meza hanyuma uhanagure byumye. Koresha amavuta ya - ingese kugirango ugumane ruswa.
Ibisabwa mububiko
Ibidukikije bigomba kuba byumye, bihumeka, kandi bikonje, birinda ubushuhe, urumuri rwizuba, hamwe na ruswa biva mubitangazamakuru bya acide cyangwa alkaline. Niba hari U - ifite ibyuma bimanika impeta y'ibikoresho bitandukanye, bigomba kubikwa ukundi. Mugihe ushyizeho, irinde kurenza metero 1.5, kuko uburebure bukabije bushobora gutera deformasiyo kumuvuduko mwinshi.
Ibipimo byo gusimbuza
Abakoresha benshi bafite iki kibazo: Ni ibihe bihe impeta yo guterura igomba gusimburwa? Kurugero, niba umubiri ufite ibice no guhindagurika kwa plastike, ahantu hafite ingese hejuru ya 30%, igifuniko cyashwanyaguritse ahantu hanini, kandi amapine na bolts birarekuye kandi ntibishobora gukomera, noneho bigomba gusimburwa.
Gukemura ibibazo
Niba hari imikorere idahwitse mugihe cyo gukoresha ariko igikoresho kirashobora gukoreshwa nyuma yo kugenzura, noneho dukeneye gukemura ikibazo. Nyuma yuko bidasanzwe bibaye, tugomba guhagarika gukoresha ako kanya igikoresho hanyuma tukareba niba umutwaro urenze, niba kwishyiriraho aribyo, cyangwa kubisimbuza ibicuruzwa byujuje ibisabwa mbere yo kubishyira mu bikorwa.
