Indawo yokuthengisa ityhubhu enkulu yecaliber rectangular

Umbhobho osikweri obubanzi obukhulu, onecandelo elinomngxuma, usetyenziswa ngokubanzi njengombhobho wokuhambisa ulwelo

Njengemibhobho yokuthutha ioli, irhasi yendalo, irhasi, amanzi kunye nezinye izinto eziqinileyo. Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi ejikelezayo, umbhobho wentsimbi unokugoba okufanayo kunye namandla okujikeleza kunye nobunzima obulula. Yintsimbi yecandelo loqoqosho. Isetyenziswa kakhulu ekwenzeni iinxalenye zesakhiwo kunye namalungu omatshini, anjengombhobho we-oyile, i-shaft yokuhambisa i-automobile, isakhelo sebhayisekile kunye ne-scaffold yentsimbi esetyenziswa ekwakheni. Ukuvelisa iindandatho zentsimbi kunye nemibhobho yentsimbi kunokuphucula ukusetyenziswa kwezinto, ukwenza lula iinkqubo zokuvelisa, kunye nokugcina izixhobo kunye neeyure zokucubungula, ezifana namakhonkco okuthwala, imikhono yeJack, njl. Umbhobho wentsimbi ukwayinto eyimfuneko kuzo zonke iintlobo zezixhobo eziqhelekileyo. Umbhobho wompu kunye nomgqomo kufuneka zenziwe ngombhobho wensimbi. Umbhobho wensimbi unokwahlulwa ube ngumbhobho ojikelezileyo kunye nombhobho owenziwe ngokukodwa ngokweendawo ezahlukeneyo ezinqamlezayo kunye nokuma. Ngenxa yokuba ummandla wesetyhula ngowona mkhulu phantsi kwemeko yesangqa esilinganayo, amanzi amaninzi angathuthwa ngombhobho ojikelezayo. Ukongezelela, xa icandelo lendandatho liphantsi koxinzelelo lwe-radial yangaphakathi okanye yangaphandle, amandla afanayo. Ngoko ke, iibhobho ezininzi zentsimbi ziyimibhobho ejikelezayo. Nangona kunjalo, umbhobho ojikelezayo nawo unemida ethile. Ngokomzekelo, phantsi kwemeko yokugoba kwendiza, amandla okugoba kombhobho ojikelezayo akanamandla njengaleyo yesikwere kunye nombhobho oxande. Imibhobho yesikwere kunye ne-rectangular isetyenziswa ngokuqhelekileyo kwisakhelo soomatshini abathile bezolimo kunye nezixhobo kunye nentsimbi kunye nefenitshala yokhuni. Imibhobho ekhethekileyo yentsimbi emile kunye nezinye iimilo zecandelo nazo ziyafuneka ngokweenjongo ezahlukeneyo.

16. steel stainless enkulu ububanzi square ityhubhu yokuthuthwa fluid (GB / T14976-2002) i eshushu-rolwa (extruded, yandisiwe) kunye ebandayo ezotywe (iqengqiwe) ubukhulu ubukhulu ityhubhu square eyenziwe ngentsimbi stainless kuthutho fluid.

17.Ityhubhu ekhethekileyo enobubanzi obuyi-square ye-square ligama eliqhelekileyo letyhubhu ye-square ene-diameter enkulu kunye nezinye iimilo zecandelo ngaphandle kwetyhubhu esetyhula. Ngokwemilo eyahlukeneyo kunye nobukhulu becandelo lombhobho wentsimbi, linokwahlulwa lube ngumbhobho okhethekileyo-ububanzi obukhulu bobubanzi obulinganayo bodonga (ikhowudi D), umbhobho okhethekileyo owenziwe ngobubanzi obunobubanzi obuhlukeneyo bodonga (ikhowudi BD) kunye nombhobho okhethekileyo wensimbi ongenamthungo kunye nobubanzi obuguquguqukayo (ikhowudi ye-BJ). Iityhubhu ezikhethekileyo ezinobukhulu obukhulu obubuxande zisetyenziswa ngokubanzi kwiindawo ezahlukeneyo zesakhiwo, izixhobo kunye namalungu oomatshini. Xa kuthelekiswa nombhobho ojikelezayo, umbhobho owenziwe ngokukodwa unomzuzu omkhulu we-inertia kunye ne-modulus yecandelo, kwaye unokugoba okukhulu kunye nokuxhathisa kwe-torsion, enokunciphisa kakhulu ubunzima besakhiwo kunye nokugcina intsimbi.

Iziphene ezininzi zetyhubhu yesikwere zibangelwa ukugqobhoza, ngoko ke inkqubo yokuhambisa amandla kwityhubhu yesikwere engenanto yinkqubo ephambili yokuvelisa ityhubhu yesikwere. Obona bunzima bokugqobhozwa kwe-alloy ephezulu bulele ekusebenzeni okuphantsi kokugqobhoza. Ukuze kuqinisekiswe umgangatho, kuyimfuneko ukuba ukhethe ngokufanelekileyo iiparamitha ze-deformation ye-perforation. Ukunyanzeliswa okuncinci kuya kubangela ukungazinzi kwinkqubo yokugqobhoza, ngoko ke xa ukunyanzeliswa okubalulekileyo kuncinci, iplagi kufuneka ibe ngaphambili, kwaye ukunyanzeliswa ngokuqhelekileyo kubekwe malunga ne-7%, kungenjalo ayiyi kuluma, okanye yandise intshukumo okanye ifumane. wancamathela ngaphambili. Ukunyuka kokunyanzeliswa phambi kweplagi kuya kwenza kwakhona umgodi womngxuma kunye nokucwilisa iziphene kwisandi. Ngoko ke, ukuba ufuna ukucombulula ingxaki yenkonzo yabathengi, umbhobho ongenanto kufuneka ugxininiswe, kwaye ubunzulu obungenanto bokugxila kufuneka buthelekiswe ngokuhambelana namanye amabakala ensimbi. Ngoko ke, inkqubo yokufudumeza iqondo lokushisa lokuphuma kunye neemfuno zomgangatho wokufudumeza. Umgangatho wokufudumeza uxhomekeke kakhulu ekusebenzeni kokufudumeza kunye nenkqubo yokufudumala. I-coefficient encinci ye-ellipticity iya kuphucula ngokubanzi umgangatho we-capillary kunye nokunciphisa i-deformation transverse. Nangona kunjalo, i-ellipse coefficient incinci kakhulu, eya kubangela ubunzima bokujikeleza kweqhekeza, kwaye ide iholele ekunxibeni kweplate yesikhokelo, ekulula ukubangela iziphene kumphezulu. Ke ngoko, ukunxiba kwepleyiti yesikhokelo kufuneka kujongwe ngokubanzi xa inqanawa ibopha umbhobho osisikwere. Emva kokuba ifunyenwe, kufuneka itshintshwe ngokukhawuleza. Iqondo le-ellipse kufuneka lilawulwe ngaphakathi koluhlu lwe-1.07-1.08. Ichaphazela ukusebenza okuqhelekileyo kweenkqubo ezilandelayo, kunye nenkqubo ephambili yokufudumeza ityhubhu yesikwere engenanto, nayo inempembelelo enkulu kumgangatho weemveliso ezigqityiweyo.
