China Slurry Pump Materials Selection fektheri le ba fanang ka thepa

Ka pompong e thellang, litšepe le kahare ea samente li lula li pepesetsoa slurry mme li tlameha ho sireletsoa ka nepo khahlanong le ho roala.
Ho khetha lintho tse tla u susumetsa le ho sebetsana le tsona ho bohlokoa joalo ka khetho ea pompo ka boeona! ”

Ho na le maemo a mararo a fapaneng a etsang hore motho a roale ka har'a pompo ea slurry:

Abrasion,Khoholeho ea mobu,Ts'enyeho

Ho its'ila

Ho na le mefuta e meraro e meholo ea abrasion:
Ka lipompo slurry re na le haholo-holo ho sila le tlaase khatello ea maikutlo abrasion.
Sekhahla sa Abrasion se ipapisitse le boholo ba phatsa le boima.

Abrasion e hlaha feela libakeng tse peli ka pompong ea slurry:
1. Pakeng tsa impeller le lesoba le emeng.
2. Pakeng tsa sleeve ea shaft le ho paka ho emeng.

Khoholeho ea mobu

Sena ke seaparo se hlaheletseng lipompong tsa slurry. Lebaka ke hore likaroloana tsa slurry li otla lintho tse holimo ka mahlakore a fapaneng.
Ts'ebetso ea khoholeho ea mobu e angoa haholo ke tsela eo pompo e sebetsoang ka eona. Khoholeho ea khoholeho ea mobu, ka kakaretso, ke bonyane ho sekhahla sa BEP-ow, 'me e eketseha ka phallo e tlase le e phahameng.
Bakeng sa mabaka a sa utloisisoeng hantle, khoholeho ea mobu le eona e ka eketseha haholo ha pompo e lumelloa ho sebetsa ho "snore"; ke hore, ho kenya moea ka har'a phala ea ho kenella.
Ho 'nile ha boleloa hore sena se ka bakoa ke ho qhekella, ka lebaka la bokahohle ba pompo bo sisinyehang ha moea o feta holim'a bona. Hona, leha ho le joalo, ho thata ho amohela e le mebutlanyana ea moea ka kakaretso e hatellang pherekano ka ho sututsa likhohlopo.
Hona le mefuta e meraro e meholo ea khoholeho ea mobu:
Phello ea khoholeho ea mobu ka likarolo tsa pompo:

Impeller

Lits'oants'o li ka ba le ts'oaetso (e phahameng le e tlase) haholo ka leihlong, lehlakoreng la lesela (A), ha turns ow e fetoha 90 °. Ka lehlakoreng le ka pele la vane (B).
Bethe e thellang le phello e tlase ea angular li etsahala haufi le li-vanes lipakeng tsa li-impeller shrouds (C).
Liners lehlakoreng (lesoba le liners morao)
Likepe tse mahlakoreng li tlas'a bethe e thellang le ho sithabetsa le ho sila.

Volute

Volute e angoa ke ho ts'oaroa ke metsi a sehiloeng. Bethe e thellang le bohlasoa bo tlase ba angular bo etsahala holima volute e setseng.
Ts'enyeho:
Ts'enyeho (le litlhaselo tsa lik'hemik'hale) tsa likarolo tse metsi ka Slurry Pump ke ntho e rarahaneng ka bobeli bakeng sa lisebelisoa tsa tšepe le elastomer.
Bakeng sa tataiso, litafole tsa ho hanyetsa lik'hemik'hale tsa tšepe le lisebelisoa tsa elastomer li fanoa ho latela le karolong ea Litafole tsa Chemical Resistance.
