Kuki indiba "zipfa zikiri nto?" Amazi ahishura amayobera y'ubuzima bwabo bugufi!

Mu 'mashyamba y'icyuma' y'imiyoboro y'inganda,indangakora nk'abakozi bakora amazi atuje, bagenzura imigendekere y'amazi. Ariko, akenshi 'bapfa bakiri bato,' birababaje rwose. Nubwo turi mubice bimwe, kuki bamwe bakoraindangaikiruhuko cyiza mugihe abandi bakomeje gukorera? Uyu munsi, reka dukurikire inzobere mu kugenzura amazi kugirango tumenye ukuri inyuma yigihe gito cyo kubahoindanga.

Impamvu eshatu zingenzi ziteraindanga"ubuzima bucye"
Suffocation to Death: Intambara ebyiri Zumuvuduko Ukabije na Ruswa Ingaruka Yumuvuduko mwinshi: Iyo umuvuduko wa sisitemu urenze kure imipaka yagenewe,indangaumubiri hamwe na kashe byatewe nigitutu kinini, biganisha kumiterere yimiterere no kunanirwa kashe. Ingaruka zamazi yinyundo ninkimvune zimbere, zishobora guhita zihindura valve idakoreshwa. Kurya ruswa: Mubihe bibi nkibidukikije by’imiti n’amazi yo mu nyanja, itangazamakuru ryangirika rikora nkimikindo yoroshya amagufwa, yicecekera yicecekeye umubyimba wurukuta rwumubiri (hamwe na ruswa ishobora kurenga 0,5 mm / mwaka), igabanya imbaraga zayo, kandi igatera gutobora no kumeneka. Amazi yumva ko ibikoresho ari ingenzi, kandi indangagaciro zayo zidasanzwe (nka Hastelloy nicyuma cya duplex) ni nk '' ingabo zinzogera zahabu, 'zongerera imbaraga imbaraga zabo no kurwanya ruswa. Kwambara Kurenza urugero: Gukata Ubugome Byihuta byihuta byitangazamakuru Media Erosion: Uduce duto cyane (nka minerval slurry n ivu) cyangwa amazi yihuta cyane (nkamazi ya cavit na cavitation) uhora ushakisha hejuru yikidodo hamwe nicyumba cya valve, bikora nkibyuma bitabarika byanditseho mikoro. Igihe kirenze, ibyo bikorwa birema ibinure byimbitse hejuru yikimenyetso, biganisha ku kunanirwa kashe. Amazi 'akomeye-akomeye cyane yometseho kashe (nka tungsten karbide na STL) hamwe nuburyo bwiza bwo gutembera bikora nk' amashati yicyuma 'kurwanya uku' guca ibihumbi. '

Guhagarika Asphyxiation: guhagarika byica umwanda nubunini

Kwinjira kwanduye: Weld slag, ingese, nibintu byamahanga birashobora kwinjira mumuyoboro hanyuma bigahagarara hagati yintebe ya valve nintangiriro. Ibi birashobora gutuma valve idashobora gufunga cyangwa gufungura neza, kandi mubihe bikomeye, byangiza ubuso bwuzuye neza. Hagati yo korohereza no gupima: Mu bihe bimwe na bimwe (nk'amazi akonje cyangwa amazi), uburyo bushobora gutondeka cyangwa gupima imbere muriindanga, gufunga neza ingingo za valve, biganisha kubunebwe cyangwa kuziba byuzuye. Ibishushanyo mbonera birwanya amazi, nk'imipira minini ya V yo mu bwoko bwa V imipira hamwe n’ibikoresho bisakara, ni ibikoresho bifatika byo gukuraho ayo maraso.

Umukoresha "ikosa" yihutishije ubuzima bwa valve

UkurikijeTWS Umuyoboro w'amazikuramba kwa valve ntabwo ari impanuka, ahubwo ni sisitemu yubuhanga kuva mubishushanyo, guhitamo ibikoresho, gukora no gukoresha:

 

Guhuza neza, Bihuye na Byihariye: Kora isesengura ryuzuye ryimikorere (igitutu, ubushyuhe, iciriritse, ibice, hamwe ninshuro ikora) kugirango uhitemo ubwoko bwiza bwa valve (irembo, umubumbe w'isi, umupira w'amaguru,ikinyugunyugu) n'ibikoresho. Ibice by'ibanze, Guharanira Gutunganirwa: Ikidodo gifatanye gikozwe mu kwihanganira kwambara no kwangirika kwangirika; igiti cya valve gikozwe mubikoresho bikomeye-byangirika kwangirika hamwe no kuvura hejuru; ibice bikomeye bitwara ibintu bigenzurwa neza binyuze mubisesengura ryanyuma (FEA). Ubukorikori, Igenzura rikomeye: Gukora neza byerekana neza kwihanganira bikwiye, kandi ikizamini gikomeye kidasenya (RT / UT / PT) gikuraho inenge zimbere; buri nzira niyiyemeza kwizerwa. Guhitamo Byubwenge, Gutegereza Kazoza: Tanga ubuyobozi bwo guhitamo umwuga hamwe nigisubizo cyabigenewe kugirango urebe ko valve 'yavutse mugihe gikwiye, ahantu heza.'

Fata neza "umutima winganda"

Kunanirwa imburagihe imburagihe nikimenyetso cyo kuburira ibibazo bya sisitemu kandi byerekana gutakaza umutungo nubushobozi. Muguhitamo Amazi, uba uhisemo ubuhanga nubwitange kugirango winjize sisitemu ya fluid hamwe nubuzima burambye. Ntabwo dutanga ibicuruzwa biramba gusa ahubwo tunateza imbere amahame yubuyobozi bwa siyansi nibikorwa bisanzwe. Gusa nukwumva, kubaha, no gufata neza abo 'bashinzwe kurinda inganda' bucece barashobora gukora neza, neza, kandi igihe kirekire muruhare rwabo, hamwe hamwe kugirango ibikorwa byinganda bigende neza!
