Mosebetsi oa pompo ea metsi

Lipompo tsa metsi li entsoe hammoho le nts'etsopele ea indasteri. Lekholong la bo19 la lilemo, ho ne ho se ho ntse ho e-na le mefuta e batlang e feletse le mefuta e sa tšoaneng ea lipompo linaheng tse ling, tse neng li sebelisoa haholo. Ho ea ka lipalo-palo, hoo e ka bang ka 1880, tlhahiso ea lipompo tsa centrifugal tsa sepheo se akaretsang e bile karolo ea 90% ea kakaretso ea tlhahiso ea pompo, ha lipompo tsa morero o khethehileng tse kang lipompo tsa motlakase, lipompo tsa lik'hemik'hale le lipompo tsa merafo li ile tsa nka karolo ea 10 lekholong feela. kakaretso ea tlhahiso ea pompo. Ka 1960, lipompo tsa morero-kakaretso li ne li etsa hoo e ka bang 45% feela, ha lipompo tsa morero o khethehileng li ne li etsa hoo e ka bang 55%. Ho ea ka mokhoa oa morao-rao oa nts'etsopele, karolo ea lipompo tsa morero o khethehileng e tla ba holimo ho feta ea lipompo tsa sepheo se akaretsang.

Hoo e ka bang mathoasong a lekholo la bo20 la lilemo, lipompo tse ka tlas'a metsi li ile tsa qaptjoa ke United States ho nka sebaka sa lipompo tsa liliba tse tebileng. Kamora moo, linaha tsa Europe Bophirima le tsona li ile tsa etsa lipatlisiso le nts'etsopele, li ntse li ntlafatsa le ho ntlafatsa butle-butle. Mohlala, morafo oa mashala a sootho oa Rhine Jeremane o sebelisa lipompo tsa motlakase tse ka tlase ho metsi tse fetang 2500, tse nang le matla a maholo a fihlang ho 1600kw le hlooho ea 410m.

Pompo ea motlakase e ka tlas'a metsi naheng ea rona e ile ea ntlafatsoa lilemong tsa bo-1960, moo pompo ea motlakase e ka tlas'a metsi sebakeng se sebetsang esale e sebelisoa ka nako e telele bakeng sa ho nosetsa masimong a ka boroa, 'me lipompo tsa motlakase tse nyenyane le tse mahareng li entse letoto. kenya tlhahisong ea bongata. Bokhoni bo boholo le lipompo tse kenang ka tlas'a metsi le li-motor tsa motlakase tse phahameng le tsona li kentsoe, 'me lipompo tse kholo tse ka tlas'a metsi tse nang le matla a 500 le 1200 kW li kentsoe tšebetsong merafong. Mohlala, Khamphani ea Anshan Iron and Steel e sebelisa pompo ea motlakase e ka tlas'a metsi ea 500kw ho hula morafo oa tšepe o bulehileng oa Qianshan, o nang le phello e kholo nakong ea lipula. Ho na le mats'oao a hore ts'ebeliso ea lipompo tsa motlakase tse ka tlas'a metsi li tla fetola lisebelisoa tsa ho ntša metsi merafong, ka monyetla oa ho nkela lipompo tse kholo tse tšekaletseng sebaka. Ho feta moo, lipompo tse kholoanyane tsa motlakase tse ka tlas'a metsi li ntse li le tlas'a tlhahiso ea liteko.

Mechini e sebelisoang ho pompa, ho tsamaisa le ho eketsa khatello ea metsi hangata e bitsoa lipompo. Ho ea ka pono ea matla, pompo ke mochine o fetolang matla a mochine oa motlakase oa pele ho matla a mokelikeli o fetisitsoeng, ho eketsa sekhahla sa phallo le khatello ea mokelikeli.

Mosebetsi oa pompo ea metsi hangata ke ho hula metsi ho tloha sebakeng se tlase ebe o a tsamaisa ka liphaephe ho ea sebakeng se phahameng. Mohlala, seo re se bonang bophelong ba rona ba letsatsi le letsatsi ke ho sebelisa pompo ho pompa metsi linōkeng le matangoaneng ho nosetsa masimo; Ka mohlala, ho pompa metsi lilibeng tse tebileng tse ka tlas'a lefatše le ho a isa litoreng tsa metsi. Ka lebaka la hore khatello ea metsi e ka eketseha ka mor'a ho feta pompong, mosebetsi oa pompo o ka boela oa sebelisoa ho ntša mokelikeli ho tloha lijaneng tse nang le khatello e tlaase le ho hlōla ho hanyetsa tseleng ea ho e isa lijaneng tse nang le matla a phahameng. khatello kapa dibaka tse ding tse hlokahalang. Ka mohlala, pompo ea metsi a phepelo ea boiler e hula metsi ho tloha tanka ea metsi a khatello e tlaase ho fepa metsi ka har'a moqomo oa boiler ka khatello e phahameng.

Mefuta ea ts'ebetso ea lipompo e pharaletse haholo, 'me tekanyo ea phallo ea lipompo tse kholo e ka fihla makholo a' maloa a likete tse m3 / h kapa ho feta; Sekhahla sa phallo ea lipompo tse nyane se ka tlase ho mashome a ml/h. Khatello ea eona e ka fihla ho feta 1000mpa ho tloha khatellong ea sepakapaka. E ka tsamaisa metsi ka mocheso ho tloha ho -200℃ho fihlela ho tse fetang 800℃. Ho na le mefuta e mengata ea lino tse ka tsamaisoang ka lipompo,

E ka tsamaisa metsi (metsi a hloekileng, likhoerekhoere, joalo-joalo), oli, lino tse nang le acid-base, li-emulsions, li-suspensions le litšepe tse metsi. Ka lebaka la hore boholo ba lipompo tseo batho ba li bonang bophelong ba bona ba letsatsi le letsatsi li sebelisoa ho tsamaisa metsi, hangata li bitsoa lipompo tsa metsi. Leha ho le joalo, joalo ka poleloana e akaretsang ea lipompo, ho hlakile hore lentsoe lena ha le na botlalo.
