Centrifugal Slurry slurry e phalla ka impeller

Ha mokelikeli o sebetsang oa Slurry ha lebili le potoloha le likarolo tse kholo hammoho , ka nako e le 'ngoe le ho tloha ho impeller e potolohang sefofaneng se seng le se seng. Mokelikeli o nang le motsamao oa ho potoloha oa impeller o bitsoa circular motion , sekhahla sa motheo se bitsoa peripheral speed , sebelisa u said . Mokelikeli o tsoang ho impeller e potolohang ka hare ho phallo e ka ntle e bitsoa motsamao o amanang le lebelo, lebelo la eona le amanang le lebelo, le hlahisoang ke mokelikeli oa W. o amanang le motsamao oa 'mele oa pompo o tsejoang e le motsamao o felletseng, lebelo la ona le bitsoa lebelo le felletseng, V e emela lebelo le felletseng la V le u. lekana le peripheral lebelo la lekanyelitsoeng velocity vector le W, ke hore, V = u + W Lebelo peripheral ea impeller khanna mokelikeli circumferential tangent line tataiso , joalokaha ho bontšitsoe 2-1a); tataiso ea tangential ho lehare le lekanyelitsoeng lebelo la mokelikeli, tataiso e feletseng ea lebelo la lebelo la mokelikeli la tataiso e pota-potileng ea lebelo le kopantseng le lebelo le lekanyelitsoeng, joalokaha ho bontšitsoe - Setšoantšo sa 2. Ho tsamaea ha metsi ka hare ho impeller ho ka emeloa ka mokhoa o hlakileng. Kerafo e bonts'ang mokelikeli ka lebelo la sets'oants'o le tsela eo motsamao o tsamaeang ka eona e bitsoa khutlotharo ea lebelo . Mokelikeli ka hare ho lebelo impeller ka ntlha efe kapa efe ka kgutlotharo ho bontšitsoe Figure 2-2. Tiileng . Ka linako tse ling,moetsi oa pompo ea seretsemolemo ka ho fetisisa ke impeller inlet le outlet mokelikeli phallo boemo.

Ha boholo ba impeller bo tsejoa , litekanyetso tse fanoeng , impeller e ka 'na ea etsoa ka kgutlotharo ea lebelo la ho kena le ho tsoa , e le hore mokelikeli o ka hlahlojoa sebakeng sa ho kenella le ho tsoa ha boemo ba phallo. E le ho etsa triangolo ea lebelo, lebelo le feletseng hangata le aroloa ka likarolo tse peli tsa orthogonal velocity: e 'ngoe ke lebelo le otlolohileng la lebelo la circumferential velocity, hangata le bitsoa axial velocity, e emeloang ke Vm; tataiso e 'ngoe e lumellana le lebelo la potoloho ea karolo ea lebelo, hangata e neng e bitsoa karolo ea circumferential velocity, le Vm e boletse, e bontšitsoeng setšoantšong sa 2-3.

Ho kgutlotharo wa velocity, angle ya lebelo le felletseng la V pakeng tsa lebelo la circumferential u e nang le angle e boletsoeng pakeng tsa lebelo la potoloho ea lebelo le lekanyelitsoeng w e emeloa ke u lipakeng tsa β.
