Impeller cutting ke mokhoa oa ho machining bophara ba impeller (lehare) ho fokotsa palo ea matla a phaella ka ho tsamaiso mokelikeli. Ho khaola li-impeller ho ka etsa litokiso tse molemo bakeng sa ho pompa ts'ebetso ka lebaka la ho feteletsa, kapa mekhoa e metle ea moralo kapa liphetoho mejaro ea sistimi.

Nako ea ho Nahana ka Impeller Cutting?

Basebelisi ba ho qetela ba lokela ho nahana ka ho seha impeller ha maemo a latelang a etsahala:

1. Li-valve tse ngata tsa tsamaiso li bulehile, tse bontšang hore lisebelisoa tsa tsamaiso li ka fumana phallo e feteletseng

2. Ho phunya ho feteletseng hoa hlokahala ho laola ho phalla ka mokhoa kapa mokhoa

3. Maemo a phahameng a lerata kapa ho thothomela a bontša ho phalla ho feteletseng

4. Ts'ebetso ea pompo e kheloha sebakeng sa moralo (e sebetsang ka tekanyo e nyenyane ea phallo)

Melemo ea ho Seha Li-Impellers

Molemo o ka sehloohong oa ho fokotsa boholo ba impeller ke ho fokotsa litšenyehelo tsa ts'ebetso le tlhokomelo. Matla a mokelikeli a fokolang a senyeha holim'a mehala ea bypass le throttles, kapa a qhalloa ka har'a sistimi joalo ka lerata le ho thothomela. Ho boloka matla ho batla ho lekana le cube ea bophara bo fokotsehileng.

Ka lebaka la ho se sebetse hantle ha li-motor le lipompo, matla a motlakase a hlokahalang ho hlahisa matla ana a mokelikeli (matla) a phahame.

Ho phaella ho matla a ho boloka matla, ho khaola pompo ea turbine ea mekhahlelo e mengata li-impellers li fokotsa ho senyeha ha liphaephe tsa tsamaiso, li-valve le litšehetso tsa liphaephe. Ho thothomela ha lipeipi ho bakoang ke ho phalla ho ka khathatsa habonolo li-welds tsa lipeipi le manonyeletso a mechine. Ha nako e ntse e ea, li-welds tse phatlohileng le manonyeletso a hlephileng li ka etsahala, tse lebisang ho lutla le ho fokotsa nako ea ho lokisoa.

Matla a feteletseng a mokelikeli le ona ha a ratehe ho latela pono ea moralo. Litšehetso tsa liphaephe li atisa ho aroloa le ho lekana ho mamella meroalo e tsitsitseng ho tloha boima ba phala le mokelikeli, khatello e tsoang khatellong ea ka hare ea sistimi, le katoloso e bakoang ke ho fetoha ha mocheso lits'ebetsong tsa thermally dynamic. Litšisinyeho tse tsoang ho matla a mokelikeli a mangata li beha meroalo e ke keng ea mamelleha tsamaisong 'me li lebisa ho lutla, nako ea ho theoha le tlhokomelo e eketsehileng.

Ho seha sehlohlolo sa pompo ea pompo ea turbine e otlolohileng ho fetola ts'ebetso ea sona ea ts'ebetso, 'me ho se ts'oanehe melaong e ts'oanang e amanang le machining a impeller ho thatafatsa likhakanyo tsa ts'ebetso ea pompo. Ka hona, bophara ba impeller ha bo fokotsehe ka tlase ho 70% ea boholo ba eona ba pele.

Lipompong tse ling, ho itšeha ho eketsa hlooho ea net positive suction head (NPSHR) e hlokoang ke pompo. Ho thibela cavitation, pompo ea centrifugal e tlameha ho sebetsa ka khatello e itseng sebakeng sa eona sa ho kena (ke hore NPSHA ≥ NPSHR). Ho fokotsa kotsi ea cavitation, phello ea ho itšeha ha impeller ho NPSHR e lokela ho hlahlojoa ho sebelisoa lintlha tsa moetsi holim'a mefuta eohle ea maemo a ts'ebetso.
