Centrifugal Pump Seal Basics
Lipompompo tsa centrifugalli sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa oli le khase, ts'ebetso ea lik'hemik'hale, kalafo ea metsi, le phepelo ea motlakase, ho tsamaisa maro hantle. E 'ngoe ea likarolo tsa bohlokoa tsa pompo ea centrifugal ke mokhoa oa ho tiisa, o thibelang ho tsoa ha metsi a pompong le ho netefatsa hore pompo e sebetsa ka mokhoa o sireletsehileng le ka katleho. Har'a mefuta e fapaneng ea litsamaiso tsa ho tiisa, litiiso tse habeli tsa mochini li sebelisoa hangata lits'ebetsong moo thibelo ea ho lutla e leng bohlokoa haholo. Leha ho le joalo, lithempereichara tse phahameng li ka baka mathata a maholo botšepehing ba litsamaiso tse peli tsa tiiso, tse ka lebisang keketsehong e kotsi ea khatello le ho hlōleha ha koluoa.
Lintho tsa motheo tsa Centrifugal Pump Litiiso
Litiiso tsa mechine ke mofuta o tloaelehileng haholo oa mokhoa oa ho tiisa o sebelisoang lipompong tsa centrifugal. Li na le likarolo tse peli tse ka sehloohong: sefahleho se emeng se tiisitsoeng le sefahleho se potolohang, tse hatisitsoeng hammoho ho etsa tiiso e tiileng. Lifahleho tsa tiiso hangata li entsoe ka thepa e tšoarellang joalo ka carbon, ceramic, kapa silicon carbide, e ka mamellang maemo a thata ka har'a pompo. Sepheo sa mantlha sa tiiso ke ho thibela mokelikeli o pompetsoeng hore o se ke oa tsoa ka har'a mokotla oa pompo ha o ntse o thibela litšila ho kena ka har'a sistimi.
Litsamaisong tsa mochini o le mong oa tiiso, sete e le 'ngoe ea lifahleho tsa tiiso e sebelisoa ho ba le mokelikeli. Leha ho le joalo, lits'ebetsong tse kenyelletsang maro a kotsi, a chefo, kapa a khatello e phahameng, hangata ho sebelisoa mochini oa tiiso o habeli. Litiiso tse peli li na le lihlopha tse peli tsa lifahleho tsa tiiso tse hlophisitsoeng ka tandem kapa ka morao ho ea morao, 'me ho na le mokelikeli oa mokoallo pakeng tsa tsona. Moqapi ona o fana ka lera le eketsehileng la tšireletso khahlanong le ho lutla le ho ntlafatsa ho tšepahala ha mokhoa oa ho tiisa.
Double Seal Systems le Melemo ea Tsona
Litiiso tse entsoeng ka makhetlo a mabeli li molemo haholo lits'ebetsong moo ho thibela ho lutla ho leng bohlokoa. Mokelikeli o thibelang metsi o pakeng tsa lihlopha tse peli tsa lifahleho tsa seal o sebetsa e le tšireletso, o thibelang mokelikeli o pompetsoeng ho balehela tikolohong. Ho feta moo, mokelikeli oa mokoallo o thusa ho tlotsa le ho pholisa lifahleho tsa tiiso, ho fokotsa ho roala le ho lelefatsa bophelo ba litiiso. Litiiso tse habeli li sebelisoa hangata ha ho sebelisoa likhatello tse phahameng, mocheso o phahameng, maro a senyang, kapa maro a kotsi tikolohong.
Ho na le mefuta e 'meli ea mantlha ea litlhophiso tsa tiiso e habeli:
Litiiso tsa Tandem: Tokisong ena, tiiso ea mantlha e shebane le mokelikeli o pompetsoeng, ha tiiso ea bobeli e sebetsa e le bekapo haeba tiiso ea mantlha e hloleha. Mokelikeli o thibelang metsi o lula o le tlas'a khatello e tlase ho feta mokelikeli o pompetsoeng ho etsa bonnete ba hore ho lutla hofe kapa hofe ho phallela ka hare ho pompo.
Litiiso tsa Morao-rao: Tokisetsong ena, lihlopha tse peli tsa lifahleho tsa tiiso li lebisitsoe ka mahlakoreng a fapaneng, 'me mokelikeli oa thibelo o bolokiloe ka khatello e phahameng ho feta mokelikeli o pompetsoeng. Tokiso ena hangata e sebelisoa lits'ebetsong tse kenyelletsang maro a sa tsitsang kapa a kotsi.
Kameho ea Lithempereichara tse Holimo ho Litsamaiso tsa Double Seal
Le hoja litsamaiso tse peli tsa tiiso li fana ka melemo e mengata, ha li sireletsehe mathateng a bakoang ke mocheso o phahameng. Lithempereichara tse phahameng li ka hlaha mehloling e fapaneng, ho kenyelletsa le mokelikeli o pompetsoeng, tikoloho ea ts'ebetso, kapa likhohlano lipakeng tsa lifahleho tsa tiiso. Ha mocheso o phahama, ho ka ba le lintlha tse 'maloa tse ka senyang botšepehi ba tsamaiso ea tiiso:
Katoloso ea Mocheso:Lithempereichara tse phahameng li etsa hore lisebelisoa tse lifahlehong tsa tiiso le likarolo tse ling li atolohe. Haeba katoloso ea mocheso e sa tšoane, e ka lebisa ho se lumellaneng ha lifahleho tsa tiiso, e leng se etsang hore ho be le ho lutla ho eketsehileng kapa ho hlōleha ha tiiso.
Khatello e Eketsehileng ho Mokelikeli oa Barrier:Mocheng oa litiiso tse peli, mokelikeli oa mokoallo o bohlokoa bakeng sa ho boloka botšepehi ba tiiso. Leha ho le joalo, mocheso o phahameng o ka etsa hore mokelikeli oa mokoallo o atolohe, e leng se lebisang keketsehong e kotsi ea khatello ka har'a kamore ea tiiso. Haeba khatello e feta meeli ea moralo oa tsamaiso ea tiiso, e ka etsa hore litiiso li se ke tsa atleha, e leng se bakang ho lutla kapa esita le tšenyo e khōlō ea pompo.
Ho senyeha ha lisebelisoa tsa Seal:Ho pepeseha ha nako e telele mochesong o phahameng ho ka etsa hore lisebelisoa tse sebelisoang lifahlehong tsa tiiso li fokotsehe. Ka mohlala, li-elastomer tse sebelisoang ho O-rings kapa gaskets li ka 'na tsa thatafala kapa tsa petsoha, ha lifahleho tsa carbon kapa ceramic seal li ka' na tsa senyeha. Ho senyeha hona ho ka senya bokhoni ba tiiso ea ho boloka mokoallo o thata, e leng se lebisang ho lutla.

Lipokotho tsena tsa khase li ka sitisa ho tlotsa le ho tsidifala ha lifahleho tsa tiiso, e leng se bakang ho hohlana ho hoholo, ho senyeha le ho hloleha ha tiiso qetellong.
Ho Fokotsa Likotsi tsa Mocheso o Phahameng
Ho thibela litlamorao tse mpe tsa mocheso o phahameng lits'ebetsong tsa tiiso e habeli, ho ka nkuoa mehato e mengata:
Khetho e nepahetseng ea thepa:Ho bohlokoa ho khetha lisebelisoa tsa tiiso tse khonang ho mamella mocheso o phahameng. Ka mohlala, li-elastomers tse phahameng tsa mocheso tse kang fluorocarbon kapa perfluoroelastomer (FFKM) li ka sebelisoa bakeng sa li-O-rings, ha li-ceramics tse tsoetseng pele kapa silicon carbide li ka sebelisoa bakeng sa lifahleho tsa tiiso.
Sheba tekanyo ea tekanyo:Ho khetha tiiso e etselitsoeng ho itšehla thajana khatello ea metsi holim'a tiiso ea mantlha.
Mekhoa ea ho Pholisa:Ho kenya lisebelisoa tse futhumatsang, joalo ka li-heaters kapa lijaki tse futhumatsang, ho ka thusa ho tlosa mocheso le ho boloka mocheso oa mokelikeli o thibelang mocheso ka har'a meeli e sireletsehileng.
