Centrifugal Slurry slurry inoyerera mune impeller

Kana Slurry inoshanda fluid kana vhiri rinotenderera neakanyanya maficha pamwechete, panguva imwe chete uye kubva kune inotenderera impeller mundege yega yega. Liquid ine rotational movement ye impeller inonzi circular motion , base rate inonzi peripheral speed , use u said . Mvura inobva kumhepo inotenderera mukati mekuyerera kwekunze inonzi hama motion , kumhanya kwayo kunoenderana nevelocity , inoratidzwa muW. mvura inoenderana nekufamba kwepombi kwemuviri kunozivikanwa seabsolute motion , kumhanya kwayo kunonzi absolute speed , ine V inomiririra absolute velocity V uye u is kuenzana nekumhanya kweparipheral yehama velocity vector uye W, kureva, V = u + W Iro peripheral speed ye impeller inotyaira mvura circumferential tangent line direction, sezvinoratidzwa mu 2-1a); kutungamira tangential kune blade hama yevelocity yemvura, iyo yakakwana yevelocity yekufamba kweiyo fluid velocity ye circumferential kutungamira kweiyo yakasanganiswa velocity uye yakaenzana velocity, sezvakaratidzwa - Mufananidzo 2. Kufamba kwemvura mukati meiyo impeller kunogona kumiririrwa nemifananidzo. Girafu rinoratidza mvura iri mukumhanya kweperesi uye kwarinofambisa rinonzi velocity triangle . Mvura iri mukati meipeller speed pane ipi zvayo yetriangle inoratidzwa muFigure 2-2. Solid . Dzimwe nguva,slurry pombi mugadziriinonyanya kukosha ndeye impeller inlet uye outlet fluid flow state.

Kana saizi ye impeller ichizivikanwa , iyo yakapihwa parameter , iyo impeller inogona kugadzirwa neye inlet uye outlet velocity triangle , kuitira kuti mvura iongororwe painopinza uye nekubuda kwenzvimbo yekuyerera . Kuitira kugadzira nhanho yenhanhatu , mhedziso yekumhanya inowanzoparara kuita zvikamu zviviri zve orthogonal velocity : imwe ndeye vertical velocity ye circumferential velocity , inowanzonzi axial velocity , inomiririrwa neVm ; imwe nzira inopindirana nekutenderera kwekutenderera kwechikamu chevelocity, kazhinji yainzi iyo circumferential velocity component, ine Vm yakati, inoratidzwa mumufananidzo 2-3.

Mugonyo renhanhatu yevalocity , kona yeabsolute velocity V pakati pe circumferential velocity u ine kona yakataurwa pakati pe sipidhi ye circumferential ye nhanho yehukama w inomiririrwa na u pakati pe β.
