Uphononongo olungumzekelo: Umzekelo weSicelo seAmerican Standard Cast Steel Globe Valves kubushushu obuphezulu kunye noxinzelelo oluphezulu lwemo engqongileyo.

"I-Case Study: Umzekelo weSicelo se-American Standard Cast Steel Globe Valves kubushushu obuphezulu kunye noxinzelelo oluphezulu lweeNdawo"

Iivalvu zeglowubhu zentsimbi zaseMelika zihlala zidibana nobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu kwizicelo zamashishini, ezibeka phambili iimfuno eziphezulu zezinto, ulwakhiwo kunye nokusebenza kwevalve. Eli nqaku liza kuphonononga ukusetyenziswa kwe-American standard cast iron globe valves kwindawo yobushushu obuphezulu kunye noxinzelelo oluphezulu ngemeko ethile, kwaye uhlalutye izinto eziphambili kuyilo kunye nenkqubo yesicelo.

Imeko yangasemva:

Kwiyunithi yokusulungekisa yeshishini lepetrochemical, ivalve yeglobhu yentsimbi esemgangathweni yaseMelika iyafuneka ukulawula ukuhamba kwemidiya ye-hydrocarbon phantsi kobushushu obuphezulu kunye noxinzelelo. Ubushushu phantsi kwale meko yokusebenza malunga 400 ° C kunye noxinzelelo ukufikelela 150MPa. Ngenxa ye-corrosiveness ephezulu kunye nokutsha okuphakathi, iimfuno ezikhethekileyo zibekwe ekukhethweni kweevalve.

1. Amanqaku oyilo

1. Ukukhethwa kwezinto eziphathekayo: Ukuqwalasela iimpawu zokushisa okuphezulu, uxinzelelo oluphezulu, kunye nemithombo yeendaba ezonakalisayo, i-valve yeglobhu yentsimbi ye-American standard cast eyenziwe nge-alloy steel material yakhethwa. Esi sixhobo sinokugcina iipropati ezilungileyo zomatshini kumaqondo aphezulu kwaye zinokuchasana okuphezulu kwimidiya ephazamisayo.
2. Uyilo lwesakhiwo: Ukuze umelane noxinzelelo oluphezulu, i-valve ithatha igobolondo eqinisiweyo kunye noyilo lwediski ukuqinisekisa ukunyaniseka kwesakhiwo se-valve phantsi koxinzelelo oluphezulu. Ngexesha elifanayo, isakhiwo sokutywinwa kabini samkelwa ukufezekisa injongo yokuvuza kwe-zero.
3. Ukuqwalaselwa kokunyuka kobushushu: Kwiindawo eziphakamileyo zokushisa, ukusebenza kwezixhobo zevalve kunye nezitywina kunokuchaphazeleka. Ngoko ke, kwinkqubo yokuyila, kuyimfuneko ukuqwalasela i-coefficient yokwandisa i-thermal yezinto eziphathekayo kunye nokusebenza kokuqina kwesitywina kumaqondo aphezulu.
4. Uvavanyo kunye nokuqinisekiswa: Ukuqinisekisa ukuba i-valve inokusebenza ngokukhuselekileyo phantsi kweemeko zokusebenza zangempela, uvavanyo olungqongqo loxinzelelo kunye novavanyo lwentsebenzo yezinto eziphathekayo luye lwaqhutywa, kwaye iziqinisekiso zokhuseleko ezifanelekileyo zifunyenwe.

2, Isiphumo sosetyenziso

1. Ukhuseleko: Emva kokufakwa, i-valve ye-globe yensimbi ye-American standard cast iphumelele ngempumelelo uvavanyo lomenzi kunye novavanyo lwendawo, ukuqinisekisa ukusebenza okukhuselekileyo phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
2. Ukuthembeka: I-valve ibonise ukuzinza okulungileyo ngexesha lokusebenza, ngaphandle kokuvuza okanye ezinye iimpazamo, ukuqinisekisa ukuqhubeka kwenkqubo yokuhamba.
3. Ukumelana nokubola: Ngenxa yokukhethwa kwezinto ezifanelekileyo, i-valve ibonisa ukuxhathisa okulungileyo kokubola xa ijongene neendaba ezitshabalalisayo, ukwandisa ubomi benkonzo yevalve.

Isishwankathelo:

Ukusetyenziswa kweevalvu zeglowubhu zentsimbi ekumgangatho ophezulu waseMelika kwindawo yobushushu obuphezulu kunye noxinzelelo oluphezulu kufuna ingqalelo ebanzi yezinto ezininzi ezinjengokukhethwa kwezinto, uyilo lolwakhiwo, iziphumo zokunyuka kobushushu, kunye nesiqinisekiso sovavanyo. Ngokufunda le meko, sinokubona ukuba ngoyilo oluchanekileyo kunye nokukhethwa kwezinto eziphathekayo, i-valve yeglobhu yentsimbi yaseMelika inokubonelela ngezisombululo ezikhuselekileyo, ezithembekileyo nezisebenzayo phantsi kweemeko zokusebenza ezigqithisileyo. Oku kunexabiso elibalulekileyo lokubhekisela kwizicelo zoshishino ezifana nokushisa okuphezulu kunye neemeko zoxinzelelo oluphezulu.
