Ulwakhiwo lweSimbi esiPhakathi saseOstreliya soRhwebo kunye neSakhiwo sokuHlala se-EPC yoLwakhiwo

Iimpawu zentsimbi zinamandla amakhulu, ubunzima obulula, ukuqina okuhle ngokubanzi, kunye nokuchasana okunamandla kwi-deformation, ngoko ke ilungele ukwakha izakhiwo ezinkulu, eziphakamileyo, kunye nezakhiwo ezinzima kakhulu;izinto eziphathekayo zine-homogeneity elungileyo kunye ne-isotropy, kwaye ilungele u-elasticity Umzimba uhambelana kakhulu neengcinga ezisisiseko zobunjineli bobunjineli jikelele;izinto eziphathekayo zineplastiki elungileyo kunye nokuqina, zinokuba ne-deformation enkulu, kwaye inokumelana kakuhle nemithwalo eguquguqukayo;ixesha lokwakha lifutshane;idigri yayo ye-industrialization iphezulu, kwaye imveliso yobuchwephesha eneqondo eliphezulu lomatshini inokuqhutywa.

Ulwakhiwo lwensimbi kufuneka lufundwe ngentsimbi ephezulu yokwandisa kakhulu amandla ayo okuvelisa isivuno;ukongeza, iintlobo ezintsha zentsimbi kufuneka iqengqiwe, njengentsimbi emile okwe-H (ekwabizwa ngokuba yintsimbi ebanzi-neflange) kunye nentsimbi emile okwe-T kunye neepleyiti zentsimbi ezifakwe kwiprofayili, njl. njl. Isidingo sezakhiwo eziphakamileyo eziphezulu.

Ukongezelela, kukho inkqubo yesakhiwo sensimbi elula ngaphandle kwebhuloho yokushisa.Isakhiwo ngokwaso asiwongi amandla.Le teknoloji isebenzisa izihlanganisi ezikhethekileyo ezihlakaniphile ukusombulula ingxaki yeebhulorho ezibandayo kunye nezishushu kwisakhiwo.Isakhiwo esincinci se-truss sivumela iintambo kunye nemibhobho yamanzi ukuba idlule eludongeni.Ukuhlobisa ukwakhiwa kukulungele.

Ukusebenza:

1. Amandla:

Isalathiso samandla sentsimbi yenziwe ngomda weelastiki σe, umda wesivuno σy, kunye nomda we-tensile σu.Uyilo lusekelwe kumandla emveliso yentsimbi.Amandla aphezulu esivuno anokunciphisa ubunzima besakhiwo, gcina intsimbi, kunye nokunciphisa iindleko.Amandla okuqina σu lolona xinzelelo luphezulu intsimbi enokumelana nayo phambi kokusilela.Ngeli xesha, isakhiwo silahlekelwa ukusebenza kwayo ngenxa yokuguqulwa kweplastiki enkulu, kodwa isakhiwo asikho isikhubekiso kwaye asiyi kuwa, esihlangabezana neemfuno zesakhiwo ukuxhathisa inyikima enqabileyo.'Σu / σy ixabiso linokuthathwa njenge parameter yogcino lwamandla entsimbi.

2. Iplastiki:

Iplastiki yentsimbi ngokuqhelekileyo ibhekisela kwipropati yokuba ne-deformation ebalulekileyo yeplastiki ngaphandle kokuphuka emva kokuba uxinzelelo ludlula isivuno.Izalathisi eziphambili zokulinganisa isakhono seplastiki sokuguqulwa kwentsimbi lubude δ kunye nokuncipha kwecandelo ψ.

3. Ukusebenza okugoba okubandayo:

Ukusebenza okubandayo okugoba kwentsimbi ngumlinganiselo wokumelana nentsimbi ekuqhekekeni xa ukuguqulwa kweplastiki kwenzeka kwiqondo lokushisa.Ukugoba okubandayo kwentsimbi kukusebenzisa umfuniselo wokugoba obandayo ukuvavanya ukusebenza ngokugoba kwentsimbi phantsi kwesidanga esichaziweyo sokugoba.

4. Ukuqina kwempembelelo:

Ukuqina kwempembelelo yentsimbi kubhekiselele kwisakhono sentsimbi ukufunxa amandla e-kinetic oomatshini ngexesha lokwaphuka phantsi komthwalo wempembelelo.Yipropathi yomatshini elinganisa ukuchasana kwentsimbi ukuchaphazela umthwalo.Inokubangela i-brittle fracture ngenxa yobushushu obuphantsi kunye noxinzelelo loxinzelelo.Isalathiso sokuqina kwempembelelo yentsimbi ngokuqhelekileyo ifunyenwe ngovavanyo lwempembelelo yemilinganiselo yovavanyo oluqhelekileyo.

5. Ukusebenza kwe-welding:

Ukusebenza kwe-welding yentsimbi kubhekiselele kumalungu e-welding kunye nokusebenza kakuhle phantsi kweemeko ezithile zenkqubo ye-welding.Ukusebenza kwe-welding kunokwahlulwa ngokusebenza kwe-welding kunye nokusebenza kwe-welding kwinkqubo ye-welding.Ukusebenza kwe-Welding kwinkqubo ye-welding ibhekisela ekuthandeni kwe-welding seam kunye nesinyithi esikufutshane ne-welding seam ukuba kungabikho iintanda ze-thermal okanye ukupholisa ukuqhekeka kwe-shrinkage ngexesha lenkqubo ye-welding.Ukusebenza kakuhle kwe-welding kuthetha ukuba phantsi kweemeko ezithile zenkqubo ye-welding, isinyithi se-weld kunye nesiseko sentsimbi esisondeleyo asiyi kuqhekeka.Ukusebenza kwe-welding ngokwemigaqo yenkonzo ibhekiselele kukuqina kwempembelelo kunye ne-ductility yendawo echaphazelekayo yobushushu kwi-weld seam.I-China yamkela indlela yokuvavanya ukusebenza kwe-welding kwinkqubo ye-welding, kwaye yamkele indlela yokuvavanya ukusebenza kwe-welding kubume bokusetyenziswa.

6. Ukuqina:

Kukho izinto ezininzi ezichaphazela ukuqina kwentsimbi.Eyokuqala kukunganyangeki kwe-corrosion yentsimbi, kwaye amanyathelo okukhusela kufuneka athathwe ukukhusela i-corrosion yensimbi kunye ne-rust.Amanyathelo okukhusela abandakanya: ukugcinwa rhoqo kweepeyinti zetsimbi, ukusetyenziswa kwentsimbi ye-galvanized, kunye nokusetyenziswa kweendlela ezikhethekileyo zokukhusela phambi kwemithombo yeendaba ezomeleleyo ezifana ne-acids, alkalis, kunye neetyuwa.I-zinc ingot igxininiswe kwijacket, kwaye i-electrolyte yamanzi olwandle iya kutshabalalisa ngokuzenzekelayo i-zinc ingot kuqala, ukuze kufezekiswe umsebenzi wokukhusela ibhatyi yensimbi.Okwesibini, ngenxa yokushisa okuphezulu kunye nomthwalo wexesha elide, amandla okutshatyalaliswa kwentsimbi aphantsi kunoko kwamandla exesha elifutshane.Ngoko ke, intsimbi yexesha elide lobushushu obuphezulu kufuneka ivavanywe ngamandla exesha elide.Intsimbi iya kuba nzima ngokuzenzekelayo kwaye ibhubhe ngokuhamba kwexesha, into eyenzekayo "yokuguga".Ukuqina kwempembelelo yentsimbi phantsi komthwalo wobushushu obuphantsi kuya kuvavanywa.

Iimveliso zentsimbi yenkampani yethu zinokuhlangabezana nemigangatho eyahlukeneyo yamazwe aphesheya njengomgangatho wase-Australia, umgangatho waseNew Zealand, umgangatho waseBritane kunye nomgangatho waseMelika.Wamkele umbuzo wakho.
