Xa ukuxinana okuphakathi kokuhambisa kukodwa, uyilo olusekelwe kwifomula yokubala engentla kunye nobubanzi bemveliso ye-outlet ye-impeller ingenza ukuba impompo igcine izinga eliphezulu lokuhamba kunye nokusebenza kakuhle.Ipompo yokukhupha i-vacuum isetyenziswe ngokubanzi kwi-petroleum, iikhemikhali zemihla ngemihla, iinkozo kunye neoli, iyeza kunye namanye amashishini.Ipompo yokujikeleza kwe-evaporator yimpompo enkulu, i-low head axial flow pump, esetyenziselwa ngokukodwa ukujikeleza ngenkani kwe-evaporators kwi-ammonium phosphate, i-phosphoric acid vacuum yemveliso yetyuwa, i-alumina, i-caustic soda, imboni yokukhanya kunye namanye amashishini.Impompo yoxinzelelo olubi yimpompo encinci yevacuum.Ngenxa yokuba inomthamo omnye kunye nombhobho wokukhupha omnye kunye nombhobho wokukhupha, kwaye unokwenza ngokuqhubekayo i-vacuum okanye uxinzelelo olubi kwindawo yokungena, uxinzelelo oluncinci olulungileyo lwenziwa kumbhobho wokukhupha.Impembelelo yeprofayili ye-blade ifundwa.Iprofayili ye-blade yi-intersection ye-flow surface ye-pump impeller kunye ne-facet kubukhulu be-blade.Ingxaki ebalulekileyo enokuthi inqume ukusebenza kwe-hydromechanical yempompo ngokuqhubekayo ukuguqula ulwelo phezu kwendawo ye-blade cell njengomthwalo wenkqubo yamandla.ipharamitha.Kuxhomekeke kwi-engile yokungena kwencakuba, i-engile yokuphuma kweblade kunye ne-engile yokuvala i-blade.Umgca weprofayili kufuphi nokungeniswa kwee-blades e-China unempembelelo ethile kwintlalontle ekusebenzeni kwempompo.Ukunyusa ngokufanelekileyo umthamo wokusingqongileyo we-hydrodynamic we-blades kumphezulu wokuhamba kwe-impeller back cover kunokunceda abafundi baphucule ukusebenza kwe-hydraulic yempompo xa behambisa imidiya enomsindo.Apha, ulwazi lwengqiqo ye-coefficient yokulungelelaniswa komthwalo luyaziswa ukuba luhlalutywe kwaye luchazwe.Okukhona umahluko omkhulu woxinzelelo phakathi komphezulu woxinzelelo kunye nomgangatho wokufunxa wencakuba, kokukhona umsebenzi weblade uwenza kulwelo, kwaye umncinci umyinge wokuqukuqela komphezulu woxinzelelo.Ngeli xesha, i-gradient yokutshintsha koxinzelelo oluguqukayo iyanda, enokuthi ibangele ukutyibilika.Ngokwee-coefficients ezihlukeneyo zomthwalo kwiindawo ezihlukeneyo zokuhamba, umsebenzi owenziwe ngamacangci kumanzi kwiindawo ezahlukeneyo zokuhamba nazo zihluke.

Eyona nto iphezulu yomthwalo we-blade kwi-flow surface yesigqubuthelo sangasemva kunye nomzobo womthwalo kwi-flow surface of the front cover of the radius efanayo.Impembelelo ye-engile yokujija i-blade kwi-engile ye-blade yokuphuma ye-five-blade isengenanto kuphando lwethiyori ekhaya nakwamanye amazwe, kwaye okwangoku ilinganiselwe kuhlalutyo lobungakanani ngokusebenzisa imifuniselo kunye neempazamo.Impembelelo ye-angle yokuphuma kwe-vane ekusebenzeni kwempompo iyahluka ngokoluhlu lweendaba ezihanjiswayo.Ukwandisa i-angle yokuphuma kwe-vane kunokunyusa ngokufanelekileyo intloko yempompo.Ukusebenza kwempompo ye-impeller ene-angle enkulu yokuphuma iphezulu kancinane kune-impeller ene-angle yokuphuma encinci, kwaye i-curve esebenzayo yendawo ephezulu yokuphumelela ilula.Nangona kunjalo, umphumo we-angle yokuphuma ekusebenzeni kwempompo ulinganiselwe, oko kukuthi, kumajelo aphakamileyo aphezulu, i-impeller ene-angle enkulu yokuphuma ayikwazi ukuthintela ukunciphisa okubukhali kokusebenza kwempompo.Izibonelelo ze-angle yokukhupha i-impeller enkulu ayinakubonakaliswa ngokupheleleyo.Xa i-medium yezothutho ye-Hertz ifikelela ekwandiseni, ukusebenza kakuhle kokumpompa kunye nentloko yehla ngokukhawuleza.Amandla e-shaft ye-impeller ene-angle yokuphuma enkulu iphezulu kakhulu kune-impeller ene-angle encinci ye-performanoutlet.Isiphumo senombolo ye-vane kwimpompo ce ayihambelani.Ukuba inani lee-blades likhulu kakhulu, ukulahleka kwe-friction yee-blades kwanda, indawo ye-flow channel iyancipha, ukusebenza kakuhle kuyancipha, kwaye ukusebenza kwe-cavitation kuyancipha.
