'Kwihlathi lentsimbi' lemibhobho yemizi-mveliso,iivalvubasebenza njengabasebenzi bamanzi abathuleyo, belawula ukuhamba kwamanzi. Nangona kunjalo, badla 'ngokufa besebancinci,' nto leyo ebuhlungu ngokwenene. Nangona beyinxalenye yeqela elifanayo, kutheni abanyeiivalvuumhlala-phantsi kwangethuba ngelixa abanye beqhubeka bekhonza? Namhlanje, masilandele ingcali yokulawula ulwelo uWaters ukuze sifumane inyaniso emva kobomi obufutshane bobomiiivalvu.
Izizathu ezintathu eziphambili zeivalvu"ubomi obufutshane"
Ukufuthanisela Ukufa: Umzabalazo Ombaxa Woxinzelelo Oluphezulu Nokugqwala Impembelelo Yoxinzelelo Oluphezulu: Xa uxinzelelo lwenkqubo ludlula kakhulu imida yoyilo lwevalvu,ivalvuUmzimba kunye nezitywini ziphantsi koxinzelelo olukhulu, nto leyo ekhokelela ekuguqukeni kwesakhiwo kunye nokusilela kwesitywini. Impembelelo yesando samanzi kwangoko ifana nokwenzakala kwangaphakathi, okunokwenza ivalvu ingasetyenziswa ngoko nangoko. Ukugqwala: Kwiimeko ezinzima ezifana neendawo zamachiza kunye namanzi olwandle, imidiya egqwalayo isebenza njengezandla ezithambisa amathambo, itshabalalisa ngokuzolileyo ubukhulu bodonga lomzimba wevalvu (ngesantya sokugqwala esidlula i-0.5 mm ngonyaka), ibuthathaka amandla ayo, kwaye ibangele ukugqobhoka nokuvuza. Amanzi ayaqonda ukuba izinto zibalulekile, kwaye iivalvu zawo ezikhethekileyo ze-alloy (ezifana neHastelloy kunye nentsimbi ye-duplex) zifana nezikhuselo zentsimbi yegolide, 'ziphucula kakhulu uxinzelelo lwazo kunye nokumelana nokugqwala. Ubunzima bokusebenza ngokugqithisileyo: Ukusikwa Okungenalusini yi-High-Speed Fluids Media Erosion: Amasuntswana aqinileyo (afana ne-mineral slurry kunye nothuthu) okanye ulwelo olukhawulezayo (afana nomphunga kunye namanzi e-cavitation) ahlala egubungula umphezulu wokuvala kunye negumbi levalvu, esebenza njengeemela ezininzi zokuqopha ezincinci. Ekuhambeni kwexesha, ezi zenzo zenza imingxunya enzulu kumphezulu wokuvala, okukhokelela ekungaphumeleli kwesitywini. Iindawo zokutywina ze-alloy yokuqina okuphezulu kwe-Waters (ezifana ne-tungsten carbide kunye ne-STL) kunye noyilo lwendlela yokuhamba kakuhle zisebenza 'njengeehempe zentsimbi' ngokuchasene 'nokunqunyulwa kwewaka' okungapheliyo.
Ukuvaleka kwe-asphyxiation: ukuvaleka okubulalayo kokungcola kunye nobukhulu
Ukungena kokungcola: Inkunkuma ye-weld, umhlwa, kunye nezinto zangaphandle zinokungena kwipayipi zize zibambeke phakathi kwesihlalo sevalvu kunye nombindi. Oku kunokubangela ukuba ivalvu ingavali okanye ivuleke kakuhle, kwaye kwiimeko ezinzima, yonakalisa umphezulu wokutywina ngokuchanekileyo. Ukwakheka kwekristale ephakathi kunye nobukhulu: Kwiimeko ezithile (ezifana namanzi okupholisa okanye i-slurry), i-medium inokuba yikristale okanye ikhule ngaphakathiivalvu, ivala ngempumelelo amalungu evalvu, nto leyo ekhokelela ekuvalekeni okucothayo okanye okupheleleyo. Uyilo lwamanzi 'oluchasene nokuvaleka, olufana neevalvu ezinkulu zebhola yohlobo lwe-V kunye nezakhiwo zokukrazula, zisebenza njengezixhobo ezisebenzayo zokususa la mahlwili egazi.'
"Impazamo" yomsebenzisi ikhawulezise ubomi bevalvu
Ngoku kaIvalvu yokutywina amanzi ye-TWS, ubude bexesha levalvu asiyongozi, kodwa bubunjineli benkqubo obuvela kuyilo, ukukhethwa kwezinto, ukwenziwa nokusetyenziswa:
Ukufanisana ngokuchanekileyo, Okulungiselelwe Okuthile: Yenza uhlalutyo olucokisekileyo lweemeko zokusebenza (uxinzelelo, ubushushu, ubuphakathi, umxholo wamasuntswana, kunye nobuninzi bokusebenza) ukuze ukhethe uhlobo olufanelekileyo lwevalvu (ivalvu yesango, ivalvu yeglobhu, ivalvu yebhola,ivalvu yebhabhathane) kunye nezinto. Izinto eziphambili, Ukulwela ukugqibelela: Isibini sokutywina senziwe nge-alloy eqinileyo engagugiyo nengagugiyo; isiqu sevalvu senziwe ngezinto ezinamandla aphezulu angagugiyo kunye nonyango oluphuculweyo lomphezulu; izinto ezibalulekileyo ezithwala uxinzelelo ziqinisekiswa ngokungqongqo ngohlalutyo lwezinto ezilinganiselweyo (FEA). Ubuchule bobugcisa, Ulawulo oluQondileyo loMgangatho: Umatshini wokulungisa ngokuchanekileyo uqinisekisa ukunyamezelana okuchanekileyo, kwaye uvavanyo olungqongqo olungatshabalalisiyo (RT/UT/PT) lususa iziphene zangaphakathi; yonke inkqubo kukuzinikela ekuthembekeni. Ukukhetha okuLungileyo, Ukulindela iKamva: Nika isikhokelo sokukhetha sobuchwephesha kunye nezisombululo ezenzelwe wena ukuqinisekisa ukuba iivalvu 'zizalwa ngexesha elifanelekileyo, kwindawo elungileyo.'
Phatha kakuhle yonke "intliziyo yezoshishino"
Ukusilela kweevalvu ngaphambi kwexesha luphawu lwesilumkiso seengxaki ezinokubakho kwinkqubo kwaye kubonisa ukulahleka kwezixhobo kunye nokusebenza kakuhle. Ngokukhetha iWaters, ukhetha ubungcali kunye nokuzinikela ekufakeni iinkqubo zakho zolwelo ngamandla ahlala ixesha elide. Asiboneleli nje kuphela ngeemveliso zeevalvu ezihlala ixesha elide kodwa sikwakhuthaza imigaqo yolawulo lwesayensi kunye nemisebenzi esemgangathweni. Kuphela ngokuqonda, ukuhlonipha, kunye nokuphatha aba 'bagcini bemizi-mveliso' abathuleyo kakuhle apho banokusebenza ngokuzinzileyo, ngokufanelekileyo, nangexesha elide kwimisebenzi yabo, bebonke beqinisekisa ukuhamba kakuhle kweenkqubo zoshishino!
