Impeller nan ponp lisier

Yon roue ponp lisier se yon eleman wotasyon nan yon ponp santrifujeur ki akselere likid soti nan sant wotasyon an, konsa transfere enèji nan motè a ki kondui ponp lan nan likid la ke yo te ponpe. Vitès la reyalize pa impeller la transfere nan presyon lè mouvman an deyò nan likid la limite pa boîtier ponp lan. Yon roue ponp lisier se yon silenn kout ak yon antre louvri (ki rele yon je) pou aksepte likid k ap rantre, vanes pou pouse likid la radial, ak yon twou splined, kle, oswa threaded pou aksepte yon arbr kondwi.

Yon roue louvri gen yon mwaye ak vanes tache epi li monte sou yon arbr. Van yo pa gen yon miray, sa ki fè roues ouvè yo yon ti kras pi fèb pase roues fèmen oswa semi-fèmen. Sepandan, kòm plak bò a pa fiks sou bò inlet nan vane a, estrès lam yo siyifikativman pi ba. Yon distans sere ant vanes ak volet ponp oswa plak dèyè anpeche pifò likid koule tounen. Mete sou bòl la ak kwen nan vane ka konpanse pa ajiste clearance a kenbe efikasite sou tan.

Yon roue semi-fèmen gen yon miray dèyè adisyonèl, ki ba li plis fòs. Impuls sa yo ka pase melanj solid-likid nan pri a nan efikasite redwi.

The construction of closed impellers includes additional back and front walls on both sides of vanes that enhances its strength. This also reduces the thrust load on the shaft, increasing bearing life and reliability and reducing shafting cost. A closed impeller's efficiency decreases as wear ring clearance increases with use. However, adjustment of impeller bowl clearance does not affect the wear on vanes as critically as open impeller. Closed impellers can be used on a wider range specific speed than open impellers.
