A  iphampu ye-turbine enezigaba eziningi  isetshenziswa kabanzi kuzinhlelo zengcindezi ephezulu, eziqhubekayo ezifana nezitshalo zikagesi, izindawo zokuhlanza amanzi, nezinhlelo zezimboni. Ukuqinisekisa ukusebenza okuthembekile kwesikhathi eside, ingxenye eyodwa ebalulekile evame ukunganakwa ivalvu yokugeleza encane, eyaziwa nangokuthi i-automatic recirculation valve (ARV). Le valve idlala indima ebalulekile ekuvikeleni iphampu ezindabeni ezinzima ezifana nokushisa ngokweqile, i-cavitation, ukudlidliza, nokungazinzi kwesistimu ngesikhathi sokusebenza kokugeleza okuphansi.

Lesi sihloko sihlola isimiso sokusebenza, izinzuzo, izimfuneko zokufakwa, namathiphu okunakekela i-valve encane yokugeleza ku-a iphampu ye-turbine enezigaba eziningi uhlelo.

1. Iyini I-Minimum Flow Valve futhi Isebenza Kanjani?

I-valve encane yokugeleza ifakwe lapho kuphuma khona iphampu ye-turbine eqondile yezigaba eziningi. Iqinisekisa ukuthi ngisho nangezikhathi zokunciphisa isidingo sesistimu, iphampu igcina isilinganiso esincane sokugeleza esidingekayo ukuvimbela ukushisa nokulimala kwangaphakathi.

I-valve isebenza ngendlela efanayo nevalvu yokuhlola futhi ilungisa ngokusekelwe kuzinga lokugeleza epayipini elikhulu:

Uma ukugeleza kwepayipi elikhulu kungaphezu komkhawulo omisiwe, indlela yokudlula isala ivaliwe.

Uma ukugeleza kwehla ngaphansi kokuncane, i-valve ivula ngokuzenzakalelayo ulayini wokudlula, iqondise kabusha ukugeleza kubuyela ku-deaerator noma ichibi, iqinisekisa ukujikeleza kabusha nokuvikelwa kwepompo.

Lolu hlelo oluzisebenzelayo lusebenzisa izinsimbi zangaphakathi zemishini nama-valve discs ukuzwa izinguquko ekuhambeni nokulungisa ngokuzenzakalelayo ukudlula ngendlela.

2. Inqubo Yokusebenza Yevaluvu Egelezayo Encane

Izimo Zokugeleza Okujwayelekile:

Lapho ukugeleza kwesistimu kuvamile, i-disc ye-valve eyinhloko ivula, futhi i-lever mechanical ivala i-bypass. Konke ukugeleza kuqondiswe kumugqa wenqubo.

Izimo Zokugeleza Okuphansi:

Njengoba ukugeleza kuncipha, i-disc eyinhloko iqala ukuvala. Uma isifike embundwini, ivala ngokugcwele iphaseji eyinhloko bese ivula kanyekanye indlela yokudlula. Lokhu kuvumela uketshezi ukuthi lujikeleze kabusha lusuka ekuphumeni kwephampu lubuyele ekumunceni iphampu noma i-deaerator, kuvimbele ukulimala kwepompo.

Lokhu kuqinisekisa ukuthi iphampu ye-turbine emile yezigaba eziningi ayilambi ukugeleza, ngisho naphakathi kokuqala, ukuvala shaqa, noma izikhathi ezidingeka kancane.

3. Izinzuzo Eziyinhloko Zokusebenzisa Ivalvu Egelezayo Encane

I-valve encane yokugeleza ihlanganisa imisebenzi eminingi yokuvikela nokulawula ibe yiyunithi eyodwa. Izinzuzo ezibalulekile zifaka:

Ukuzilawula okuzenzakalelayo:Isebenza ngokusekelwe ezinguqukweni zokugeleza ngaphandle kwamandla angaphandle noma amasiginali okulawula.

Ukulawula ukugeleza kwe-bypass:Yehlisa ukulahleka kwamandla ngokugwema ukujikeleza kabusha okuqhubekayo.

Hlola ukusebenza kwe-valve:Kokubili umugqa oyinhloko kanye nokudlula kuhlanganisa amakhono angabuyi.

Idizayini yokonga isikhala:Umzimba omise okwezindlela ezintathu wenza lula ukwakheka kwamapayipi.

Ukusebenza ngendlela eyonga amandla:Asikho isidingo sokugeleza kwe-bypass njalo, ukunciphisa ukusetshenziswa kwamandla wesistimu.

Kwehlisiwe inkimbinkimbi yesistimu:Ihlanganisa izingxenye eziningi zibe yinto eyodwa, idizayini enciphisa kanye nomsebenzi wokuthenga.

Izindleko eziphelele eziphansi:Inciphisa ukutshalwa kwezimali kokuqala, ukufakwa, kanye nezindleko zokunakekela zesikhathi eside.

Ukwethembeka okuthuthukisiwe:Yehlisa ingozi ye-cavitation kanye nokwehluleka kwemishini ngaphansi kwezimo zokugeleza okuphansi.

Ukuvikelwa kwepompo ngaphansi kwazo zonke izimo zokugeleza:Igcina ukusebenza okuphephile kwephampu ye-turbine eqondile yezigaba eziningi, ngisho naphakathi nokugeleza okungavamile.

Ukusebenza kwamahhala:Ukwakhiwa kwemishini okunamaphuzu amancane okuhluleka futhi akukho zilawuli zangaphandle.

4. Imihlahlandlela yokufaka

Ukuqinisekisa ukuthi i-valve encane yokugeleza isebenza kahle:

Indawo:Faka i-valve eduze ngangokunokwenzeka ekuphumeni kwepompo—okungcono phakathi kwamamitha angu-1.5—ukunciphisa umsindo nengozi yesando samanzi.

Isifundo:Ukufakwa okuqondile (ukugeleza kusuka phansi kuya phezulu) kuyathandwa, kodwa ukufakwa okuvundlile nakho kungenzeka.

Indlela yokudlula:Qinisekisa ukuthi umzila ogelezayo ubuyela ku-deaerator, ithangi, noma indawo yokumpompa ukuze ujikeleze kabusha ngempumelelo.

5. Izincomo Zokunakekela Nokunakekela

Ukwandisa impilo ye-valve encane yokugeleza nokuqinisekisa ukusebenza okuthembekile:

Isitoreji:Gcina endaweni eyomile, engenawo umoya; vala iziphetho zombili ukuze uvimbele ukungena kwemfucumfucu.

Ukuhlola ngaphambi kokusetshenziswa: Qinisekisa ilebula yevalvu, hlola indawo evalekayo kanye nengaphakathi langaphakathi ukuze uthole ukungcola.

Ukuhlola okuvamile:Ngemuva kokufakwa, hlola ngezikhathi ezithile izindawo zokuvala kanye nama-O-rings. Shintsha noma lungisa izingxenye ezigugile ngokushesha.

Ukuhlanza:Gcina izingxenye zangaphakathi zihlanzekile ukuze ugweme ukuvinjelwa noma ukwehluleka kwevalvu.

Isiphetho

I-valve encane yokugeleza iyisivikelo esibalulekile sanoma iyiphi i-multistage vertical turbine pump esebenza ngaphansi kwezimo zokugeleza eziguquguqukayo. Iqinisekisa ngokuzenzakalelayo ukubuyiswa kabusha okuncane ukuvimbela umonakalo obangelwa i-cavitation, ukushisa ngokweqile, nokugijima okomile-izinkinga ezivame kakhulu ku-high-pressure, izinhlelo ezibucayi. Ngemisebenzi yayo edidiyelwe, ubulula bemishini, kanye nomklamo wokonga amandla, i-valve inikela ekusebenzeni okuthembekile nokungabizi kakhulu kwezinhlelo zephampu ye-turbine eqondile.

Ngempilo yesistimu yesikhathi eside nokuvikelwa kwephampu, ukufaka i-valve encane yokugeleza akusona nje isincomo—kuyisidingo.
