Injongo yonyango lobushushu obuqaqambileyo kwi-intanethi yensimbi engenasici yemibhobho edityanisiweyo: enye kukuphelisa uxinzelelo olushiyekileyo oluveliswa ngexesha lenkqubo yokusebenza ebandayo yokuqengqeleka komtya wentsimbi kwimilo ye-tubular kwaye ngexesha lenkqubo ye-welding;Yinkqubo ebalulekileyo yokuqinisekisa ukusebenza kwemibhobho edityanisiweyo yensimbi engenasici kwisisombululo esiluqilima kwi-austenite kwaye emva koko iphole ngokukhawuleza ukuthintela i-austenite kwimvula okanye ukuguqulwa kwesigaba ngexesha lenkqubo yokupholisa.
Imiba echaphazela uNyango loBubushushu obuKhazimulayo kwi-Intanethi
1. Impembelelo yobushushu bonyango lobushushu
Unyango lwesisombululo yeyona nkqubo isebenzayo yokuthambisa i-austenitic steel stainless steel.Umbhobho odityanisiweyo emva konyango lwesisombululo unokufumana ukuchasana kokugqwala, amandla aphantsi kunye neplastiki engcono.Kuphela ngale ndlela inokuhlangabezana neemfuno zemibhobho yezoshishino njengemibhobho ye-condenser kunye nemibhobho yekhemikhali.
Ngokweemfuno ezisemgangathweni zemibhobho yensimbi engenasici ye-condensers, ubushushu bonyango lobushushu lwe-austenitic steel stainless steel welded imibhobho kufuneka lufikelele kwi-1050 ~ 1150 ℃.Kwangaxeshanye, kukwafuneka ukuba iindawo zangaphakathi nangaphandle zemibhobho edityanisiweyo emva kokuba unyango lobushushu lube mhlophe kwaye lugudileyo, ngaphandle kombala we-oxidation.Ngoko ke, kufuneka kube ngqongqo ngexesha lokufudumala kunye nokupholisa imibhobho edibeneyo.Ukulawula uluhlu lokutshintsha kweqondo lokushisa (kumzimba wesithando somlilo), umbhobho wentsimbi kufuneka ube kwindawo efanelekileyo yokukhusela, kwaye indlela yokucima amanzi yendabuko ayinakusetyenziswa ukuthintela umbhobho wentsimbi obushushu obuphezulu ekubola kweoksijini kunye ne-oxidizing ebusweni bombhobho. .Ngokuqhelekileyo, ubushushu bonyango lwesisombululo se-austenitic steel stainless yi-1050 ~ 1150 ℃.Ukuba eli qondo lokushisa alifinyelelwanga, isakhiwo sangaphakathi se-austenitic stainless steel asizinzile, kwaye i-carbides iya kudlula, okubangela ukuba ubuso bombhobho wensimbi ungafikeleli kumbala oqaqambileyo, kwaye umphezulu wombhobho uya kubonakala umnyama.
2. Impembelelo yegesi yokukhusela
Unyango olushushu lwensimbi engenasici edityanisiweyo yombhobho luthatha i-oxidation-free eqhubekayo yonyango lweziko lobushushu kunye negesi ekhuselayo, enokufumana indawo eqaqambileyo ngaphandle kwe-oxidation, ngaloo ndlela iphelisa inkqubo yokukhetha yendabuko.Iigesi ezikhuselayo ezinokuthi zisetyenziswe yi-hydrogen ephezulu, i-ammonia ebolileyo kunye nezinye iigesi ezikhuselayo.Ekubeni i-stainless steel welded pipe iqulethe i-chromium, akunakwenzeka ukwenza unyango lobushushu obuqaqambileyo kwigesi eqhelekileyo yokukhusela (njengegesi yokubola kwe-hydrocarbon, njl.), kwaye kukulungele ukuyenza kwindawo yokucoca.Nangona kunjalo, ukunyangwa kobushushu kwimibhobho edibeneyo yensimbi engenasici, indawo ye-vacuum ayinakusetyenziswa, kwaye igesi ye-inert (efana ne-argon) ingasetyenziswa.Nangona ukusetyenziswa kwerhasi engasebenziyo njengerhasi ekhuselayo yonyango lobushushu lwemibhobho edityanisiweyo yentsimbi ye-austenitic ineempawu zokungathabathi nxaxheba kwiimpendulo zemichiza, umsebenzi olula, ukhuselekile kwaye uthembekile, kodwa awunayo iipropati zokunciphisa, ukuze isiphumo sonyango lobushushu. ayinakuhlangabezana neemfuno ezifanelekileyo zomgangatho wobushushu obuqaqambileyo.Silver grey.Ngaphezu koko, ixabiso legesi ye-inert liphezulu kwaye ayifanelekanga kwimveliso enkulu.Ngokutsho uphando kwinkqubo yonyango ubushushu kunye nohlalutyo kunye neemvavanyo eziphindaphindiweyo kumgangatho wentsimbi yentsimbi edityanisiweyo umbhobho emva unyango ubushushu obuqaqambileyo, indlela yokuqala usebenzisa igesi engasebenziyo ukuhlambulula umoya kwiziko lonyango lobushushu, kwaye ke endaweni igesi ye-inert ene-hydrogen, ibonakalise ukuba unyango lobushushu obuqaqambileyo luphunyeziwe.Iimfuno zomgangatho. IHangao Tech (SEKO Machinery) ukugcinwa kobushushu eqaqambileyo annealing ubushushu annealing umatshini ukunyanga sisixhobo online uhlobo, ngokukodwa eyenzelwe intsimbi stainless imigca edityanisiweyo yokuvelisa umbhobho.
3. Impembelelo yobushushu bokupholisa
Emva kokufudumeza umbhobho odityanisiweyo wensimbi engenasici ukuya kwi-1050 ~ 1150 ℃, umbhobho odityanisiweyo kufuneka upholiswe ngokukhawuleza.kufuneka ithotywe kwiqondo lobushushu elingena oxidize.Ngoko ke, iqondo lokushisa lokupholisa libaluleke kakhulu, kwaye uluhlu lweqondo lokushisa kufuneka lilawulwe ngokungqongqo.

4. Impembelelo yendawo yombhobho odityanisiweyo
Ubume bobuso bombhobho odibeneyo wensimbi engenasici ngaphambi kokungena eziko kunempembelelo enkulu kunyango lobushushu obuqaqambileyo.Ukuba ubuso bombhobho odibeneyo buhlanjululwe ngumswakama, igrisi kunye nolunye ukungcola kwisithando somlilo, umbala oluhlaza okhanyayo we-oxide uya kubonakala phezu kombhobho odibeneyo emva kokunyangwa kobushushu obuqaqambileyo.Ngoko ke, ngaphambi kokungena kwisithando somlilo sokushisa, umphezulu wepayipi yensimbi engenasici kufuneka ihlambuluke kakhulu, kwaye umphezulu wombhobho odibeneyo akufanele uvunyelwe ukuba ube nomswakama.Ukuba kuyimfuneko, inokomiswa kwi-dryer kuqala, kwaye ifakwe kwisithando somlilo.
5. Impembelelo yoNyango lweSiko lokutywinwa kweSiko
Isithando somlilo sokushisa kufuneka sivalwe kwaye sihlukaniswe ngaphandle emoyeni.Ngokukodwa indawo apho umbhobho odibeneyo ungena khona kumzimba wesithando somlilo kunye nendawo apho umbhobho odibeneyo uphuma khona emzimbeni wesithando somlilo, ikhonkco lokutywinwa kwezi ndawo lilula kakhulu ukunxiba, ngoko kufuneka lihlolwe rhoqo kwaye litshintshwe ngexesha.Ukuze kuthintelwe ukuvuza kwe-micro, igesi yokukhusela kwisithando somlilo kufuneka igcine uxinzelelo oluthile oluhle.Ukuba yigesi yokukhusela i-hydrogen, ngokuqhelekileyo kufuneka ibe mkhulu kunoxinzelelo oluqhelekileyo lwe-atmospheric.
6. Impembelelo yezinye izinto kunyango lobushushu obuqaqambileyo
Ngethuba lenkqubo yokusebenza, kuyimfuneko ukuqinisekisa ukuba i-welding iyaqhubeka kwaye izinzile.Xa kukho imingxuma okanye i-seams kumbhobho odibeneyo, umsebenzi wesithando somlilo kufuneka umiswe, ngaphandle koko umbhobho odibeneyo unokuvuthelwa esithandweni.Ukongezelela, umphumo we-welding awulungile, kwaye umoya okanye umswakama otshisiweyo ukusuka kumngxunya we-welding uya kutshabalalisa umoya wokukhusela kwisithando somlilo kwaye uchaphazele umphumo wokushisa oqaqambileyo.
