Ukuphononongwa koKuchasa ukuRhakala: Ukukhethwa kwezinto kunye nokuSetyenziswa kweMigangatho yaseJamani iBellows Globe Valves
"Uphononongo lokuchasa ukuRhakala: Ukukhethwa kwezinto kunye nokuSetyenziswa kweMigangatho yaseJamani iBellows Globe Valves"
Kwiinkqubo zokulawula ulwelo, ivalve yeglowubhu ye-bellows yaseJamani isetyenziswe ngokubanzi ngenxa yesakhiwo sayo esisodwa kunye nokusebenza okugqwesileyo. Phakathi kwazo, ukuxhathisa kwayo kwe-corrosion yenye yezibonakaliso ezibalulekileyo zokuvavanya umgangatho wayo kunye nobomi benkonzo. Eli nqaku liza kugxila ekuphononongeni ubudlelwane phakathi kokhetho lwezinto ezisemgangathweni zaseJamani iivalvu zeglowubhu zeglowubhu kunye nokusebenza kwazo ukuxhathisa umhlwa, kwaye ukwazisa usetyenziso lwazo kwiimeko ezahlukeneyo zesicelo.
I-1, Impembelelo yokukhethwa kwezinto eziphathekayo ekusebenzeni kokuxhathisa ukubola
Ukumelana nomhlwa kwemigangatho yeglowubhu yeGerman standard bellows ikakhulu kuxhomekeke kukhetho lwemathiriyeli yazo. Izinto ezisetyenziswa ngokuqhelekileyo kwi-bellows globe valves kwimarike yangoku ziquka insimbi engenasici, i-carbon steel, i-copper, njl. Ezi zixhobo nganye zineempawu zazo kwaye zifanelekile kwiindawo ezahlukeneyo zokusebenza kunye neendaba.
Izinto zensimbi ezingenasici zisetyenziswa kakhulu kwiinkqubo zokulawula ulwelo kumashishini afana neekhemikhali, amayeza, kunye nokutya ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, ukumelana nobushushu obuphezulu, kunye nokumelana nokunxiba. Kwiivalvu zeglobhu eziqhelekileyo zaseJamani, ukusebenzisa imathiriyeli yensimbi engenasici kunokumelana ngokufanelekileyo nokhukuliseko lwemithombo yeendaba ezonakalisayo kunye nokwandisa ubomi benkonzo yesivalo.
Iivalvu zeglowubhu zentsimbi zekhabhoni zineempawu ezinjengokumelana noxinzelelo, ukuqina okuphezulu, kunye nokutywinwa okulungileyo, okuzenza zilungele ukusetyenziswa ngokubanzi njengobushushu obuphantsi, uxinzelelo oluphantsi, kunye nemithombo yeendaba engonakalisi. Kwiimeko ezithile zesicelo, izinto ze-carbon steel nazo zinokuhlangabezana neemfuno zokumelana nokubola, kwaye ixabiso layo liphantsi, elinomlinganiselo othile wezoqoqosho.
Ivalve yeglowubhu yombhobho ethathiweyo eyenziwe ngezinto zobhedu ine-conductivity entle, ukumelana ne-oxidation, uzinzo lobushushu obuphezulu kunye nezinye iimpawu, kwaye ifanelekile kwimidiya ye-thermal conductivity ephezulu, njengamanzi okupholisa, i-condensers, njl njl. Izinto zobhedu nazo zineqondo elithile. yokuxhathisa i-corrosion, enokumelana nokhukuliseko oluphakathi ukuya kumlinganiselo othile.
2, Ukusetyenziswa kokumelana nokuCorrosion kwemigangatho yeglowubhu yaseJamani
Kwizinto ezibonakalayo, ukusebenza kokunganyangeki komhlwa kweevalvu zeglowubhu zeglowubhu ezisemgangathweni zaseJamani kubonisiwe ngokupheleleyo. Kwimizi-mveliso efana neekhemikhali kunye namashishini amayeza, ngenxa yendalo eyingozi ye-medium egqithiswayo, i-valve yeglobhu yombhobho eyenziwe ngamatye eyenziwe ngezinto ezinokumelana nokugqwesa okugqwesileyo kunokuphepha ngokufanelekileyo ukukhukuliseka kwe-medium kwi-valve kunye nokuqinisekisa ukusebenza okuzinzileyo kwenkqubo.
Ukongeza, kwiinkalo ezifana nobunjineli baselwandle kunye nokucocwa kogutyulo, ngenxa yemekobume erhabaxa kunye neendaba ezintsonkothileyo, iimfuno eziphezulu zibekwe phambili ukuze kusebenze ukuxhathisa ukonakala kweevalvu zeglowubhu yombhobho emdaka. Kwezi meko, iivalvu zeglobhu eziqhelekileyo zaseJamani ezenziwe ngentsimbi engenasici okanye izinto ezikhethekileyo zealloy zinokuziqhelanisa ngcono nendawo yokusebenza, ziqinisekise ukuthuthwa kolwelo olukhuselekileyo kunye nolawulo.
3, Isiphelo
Isishwankathelo, uxhathiso ekumdleni kweevalvu zeglowubhu ezisemgangathweni zaseJamani zisondelelene nokhetho lwazo lwemathiriyeli. Ngokukhetha izinto ezifana nentsimbi engatyiwayo, intsimbi yekhabhoni, kunye nobhedu ngokufanelekileyo, kunye nokulungelelanisa uyilo ngokweemeko zokwenyani zesicelo, inokuqinisekisa ukuba ivalve yeglowubhu inozinzo oluhle kunye nokuthembeka kwimidiya eyonakalisayo. Ngeli xesha, kunye nophuhliso oluqhubekayo lwesayensi yezinto kunye nokuvela kwezinto ezintsha, ukusebenza kokumelana nokubola kwezivalo zeglobhu eziqhelekileyo zaseJamani ziya kuphuculwa ngakumbi kwixesha elizayo, ukubonelela ngesiqinisekiso esiqinileyo sokusebenza ngokukhuselekileyo kweenkqubo zokulawula ulwelo.
Kufuneka kuqatshelwe ukuba nangona ezi zixhobo zinokumelana ne-corrosion, zisafuna ukukhethwa kwaye zihlolwe ngokusekelwe kwiindawo ezithile zokusebenza kunye neempawu eziphakathi kwizicelo eziphathekayo. Ukongezelela, ukugcinwa rhoqo kunye nokuhlolwa kungundoqo ekuqinisekiseni ukusebenza okuzinzile kwexesha elide le-valve. Ngokukhetha imathiriyeli yenzululwazi, uyilo olufanelekileyo, kunye nolawulo olusebenzayo lokulondolozwa, ukusebenza kokumelana nomhlwa kwemigangatho yeglobhu yeglobhu yombhobho yamalahle esemgangathweni yaseJamani ingasetyenziswa ngokupheleleyo, ibonelela ngenkxaso ethembekileyo yemveliso yemizi-mveliso kunye neenkqubo zolawulo lonikezelo lwamanzi oluntu.
