I-slurry volume loss runtime Slurry in operation, impompo yoxinzelelo lwempompo kuwo wonke umzimba ayilingani, indawo yoxinzelelo oluphezulu, kukho indawo yoxinzelelo oluphantsi.Ekubeni iimfuno zesakhiwo, kukho izithuba ezininzi kumzimba wempompo, xa umsantsa ujikeleze uluhlu loxinzelelo, ulwelo luya kumpompoza ukusuka kwindawo yoxinzelelo oluphezulu ukuya kwindawo yoxinzelelo oluphantsi, le nxalenye yoxinzelelo oluphezulu lolwelo lubuyela ngaphakathi. ummandla woxinzelelo oluphantsi, ngelixa ujikeleza ngokusebenza kwamandla kufumaneka xa i-impeller, kodwa kungekhona ukusetyenziswa okusebenzayo, kodwa ukujikeleza komzimba wempompo, ngenxa yokuba i-gap ukunqoba ukuchasana kunye nokudliwayo, le lahleko yamandla ibizwa ngokuba yi-volume loss.
Njengoko ulwelo oluphuma kwinxalenye ye-impeller kwimpompo ngasemva, alukhutshwanga kumpompo, izinga lokuphuma kwempompo lokukhutshwa kwempompo Q lomlinganiselo onguwo womlinganiselo wesantya sokuhamba nge-impeller Q 'ibe yincinci.
Ukuhlelwa kokulahleka komthamo
(1) apho ukungena kwe-impeller, i-impeller kunye nomzimba wempompo unesithuba esincinci sokutywina.Uxinzelelo ngaphakathi kumngxunya wempompo ye-impeller yokungenisa kunophezulu, ngoko kukho umsantsa omncinci osuka kulwelo lwesitokhwe ngetywina ubuyela kwi-impeller inlet impeller exit.Le nxalenye yolwelo njenge-impeller ye-bid eyimpumelelo isetyenziswa ngokufanelekileyo, kwaye ilahleko kukoyisa ukuxhathisa kwe-gap yetywina.Ngokuqhelekileyo, le nxalenye yelahleko yamandla ibizwa ngokuba yi-seal ring leakage loss.Amanzi akhoyo ahamba ngobuchwephesha befomula ukubala ubungakanani bokuvuza kwiringi yokutywina q1 (m ^ 3 / s): ulwelo olomileyo okanye ulwelo olunolwelo oluluqilima ecaleni kwempompo yeenkozo, ukukhutshwa kweringi yetywina kufuneka ibe nkulu kunexabiso elikwiThebhile yesi-2 -1 kancinci .Umsantsa wokutywina ubude l inokumiselwa ngokwesakhiwo esithile.
(2) Ngokubanzi i-centrifugal axial force balance kuwo omabini amaziko, njenge-bancing hole (Umfanekiso 2-11) kunye nepleyiti yebhalansi njalo njalo.Nangona inxalenye yolwelo efunyenwe kwi-impeller yamandla, kodwa ingasetyenziswanga ngokufanelekileyo kwaye isetyenziselwe ukoyisa ukuxhathisa ngokulinganisa indlela, ekwayinxalenye yokulahleka komthamo kwilahleko yamandla.Ekuvunyweni kwe-multi-stage pump balancing disc kubalwa komthamo wokuvuza kwamanzi kuya kuxoxwa kwiSahluko VII.Kwixabiso lokuvuza ngomngxuma wokulinganisa unokuqikelelwa ngefomula (2-13), ubukho bempompo yomngxuma elungeleleneyo iya kuba yi-3-6%.
Ukongeza, impompo yamanqanaba amaninzi, ukongeza kwezi zintlu zimbini zingasentla ziyinxalenye yokulahleka kwevolumu yokuvuza, akukho nxalenye yokuvuza kokulahleka komthamo wokuvuza.Kwiimpompo zamanqanaba amaninzi ziqhelekile ipleyiti yolwahlulo lwenqanaba, kuba inqanaba lolwelo emva kwepleyiti yolwahlulo loxinzelelo liyahluka,umenzi wempompo enodakangoko ke isahlulo solwelo ngaphaya kwinqanaba elibuyela kumsantsa wepleyiti phakathi kwecala le-impeller yokucoca kwangaphambili, umsantsa wokuvuza phakathi komgangatho wolwelo, phakathi kwe-impeller kunye ne-guide vane backlash emva kokuxubana nolwelo olusuka kwi-impeller, Isikhokelo se-vanes kunye namagqabi e-ABM, kodwa kunye nomsantsa wenqanaba phakathi kwe-impeller umva kwi-pre-backlash, njalo njalo.Ekubeni le nxalenye ye-liquid ayidluli kwi-impeller, ayichaphazeli ukuhamba kwempompo, ngoko ke le nxalenye yelahleko zamandla ayikho ilahleko yomthamo.
