Iiflange ezinobubanzi obukhulu zisetyenziswa ngokubanzi kumashishini oomatshini

Inkcazo: Eli nqaku lazisa iimeko ezisebenzayo kunye neenkqubo zokwenziwa kweeflange ezinobubanzi obukhulu.

Iiflange ezinobubanzi obukhulu zisetyenziswa ngokubanzi, kwaye ububanzi besicelo bunqunywe ngeempawu zabo. Zisetyenziswa kakhulu kuxinzelelo oluphantsi (uxinzelelo lwegama alugqithi kwi-2.5MPa) umoya ocinezelekileyo ongacocwanga, uxinzelelo oluphantsi olujikelezayo lwamanzi kunye nezinye iimeko ezineemeko zeendaba ezikhululekileyo, kwaye zinenzuzo yokuba nexabiso eliphantsi. Izinto eziphathekayo ziyi-carbon steel, insimbi engenasici kunye nentsimbi ye-alloy, njl.

Iiflange eziqhelekileyo ezinobubanzi obukhulu zibandakanya iiflange ze-welding ezisicaba kunye ne-butt welding flanges, kunye ne-diameter enkulu ene-threaded flanges inqabile kakhulu. Kwimveliso yokwenene kunye neentengiso, iimveliso ze-welding flat zisabala umlinganiselo omkhulu. I-Flat welding enkulu-diameter flanges kunye ne-butt welding enkulu-diameter flanges inezakhiwo ezahlukeneyo kunye noluhlu lokusetyenziswa, kunye neempawu kunye neenzuzo ezinokuboniswa nazo ziya kwahluka. Ngoko ke, xa uzisebenzisa, kufuneka zisetyenziswe kwiindidi ezahlukeneyo zokuqinisekisa ukuba i-flange idlala indima ebalulekileyo. I-flanges ye-welding flat-diameter enkulu inobunzima obungaguqukiyo kwaye ifanelekile kwizihlandlo ezinoxinzelelo p≤4MPa; iiflange zokuwelda iimpundu ezinkulu ezinobubanzi obukhulu zikwabizwa ngokuba zii-flanges ezinobubanzi obukhulu bentamo, ezinokuqina okukhulu kwaye zilungele iimeko ezinoxinzelelo oluphezulu kunye nobushushu.

Kukho iintlobo ezintathu zeendawo zokutywina ezinobubanzi obukhulu be-flange:

1. Umphezulu wokutywina we-Flat, ofanelekileyo kwizihlandlo ezinoxinzelelo oluphantsi kunye neendaba ezingenayo inetyhefu;

2. Umphezulu weconcave kunye neconvex yokutywina, efanelekileyo ngamaxesha anoxinzelelo oluphezulu kancinci;

3. Umphezulu wokutywina we-Tenon kunye negroove, olungele ukutsha, uqhushumbo, imidiya eyityhefu kunye nezihlandlo zoxinzelelo oluphezulu. Ukufakwa kombhobho weFlange weempawu ezahlukeneyo zinemveliso elungileyo kwiinkalo ezahlukeneyo, kwaye iziphumo eziveliswayo ziya kuhluka ngokuxhomekeke kwizihlandlo kunye neendawo ezifanelekileyo.

Inkqubo yokuveliswa kwee-flanges zensimbi ezingenasici ezinobubanzi obukhulu zihlukaniswe zibe yi-rolling and forging

Inkqubo yokuqengqeleka: Inkqubo yokusika imicu ukusuka kwipleyiti ephakathi kwaye emva koko iqengqeleke kwisangqa ibizwa ngokuba yi-rolling, esetyenziswa kakhulu ekuveliseni ezinye iiflange ezinkulu zentsimbi. Emva kokuba ukuphumelela kuphumelele, i-welding iqhutyelwa, emva koko i-flattening, kwaye ke inkqubo yamanzi kunye ne-bolt hole icutshungulwa.

Iiflange ezinobubanzi obukhulu obuyingqinisiso ngokubanzi zinomxholo ophantsi wekhabhoni kuneeflange eziphonsiweyo ezinobubanzi obukhulu, akukho lula ukurusa, zineentsika ezilungelelanisiweyo ezilungelelanisiweyo, zixinene ngakumbi kulwakhiwo, zineempawu ezingcono zoomatshini kuneeflange ezinobubanzi obukhulu, kwaye ziyakwazi ukumelana nokucheba okuphezulu. kunye nemikhosi eqinile

Inkqubo yokubumba ngokubanzi iquka la manyathelo alandelayo, oko kukuthi, ukukhetha iibhilidi zentsimbi ezikumgangatho ophezulu zokugquma, ukufudumeza, ukubumba, kunye nokupholisa emva kokwenziwa. Iindlela zenkqubo yokubunjwa zibandakanya ukubunjwa kwamahhala, ukubunjwa kwefa kunye ne-membrane forging. Ngexesha lokuvelisa, iindlela ezahlukeneyo zokubumba zikhethwa ngokuhambelana nomgangatho wokubunjwa kunye nenani leebhetshi zokuvelisa.

Ukwenziwa kwasimahla kunemveliso ephantsi kunye nesibonelelo esikhulu somatshini, kodwa izixhobo zilula kwaye ziguquguquka, ngoko ke zisetyenziswa ngokubanzi ukwenza iziqwenga ezingatshatanga kunye neebhetshi ezincinci zokubumba ezinemilo elula. Izixhobo zokubumba zasimahla ziquka iihamile zomoya, iihamile zomoya womphunga kunye noomatshini boxinzelelo lwehydraulic, ezifanelekileyo ukuveliswa kwezinto ezincinci, eziphakathi kunye nezinkulu ngokulandelelanayo.

Ukubumba imodeli kukubeka i-billet eshushu kwi-forging die esisigxina kwisixhobo sokubumba sokufa. I-Die forging inemveliso ephezulu, umsebenzi olula, kwaye kulula ukuyitshintsha kunye nokuzenzekelayo. I-Die forgings inokuchaneka okuphezulu komgangatho, isibonelelo somatshini omncinci, kunye nokuhanjiswa kolwakhiwo olufanelekileyo lwefayibha, enokuphucula ngakumbi ubomi benkonzo yamalungu.
