Impompo yequla elinzulu yimpompo yenqanaba le-multistage centrifugal, enokuphakamisa amanzi kumaqula anzulu.Ngokuhla komgangatho wamanzi aphantsi komhlaba, iimpompo zamaqula anzulu zisetyenziswa kakhulu kuneempompo eziqhelekileyo ze-centrifugal.Nangona kunjalo, ngenxa yokhetho olungafanelekanga, abanye abasebenzisi baneengxaki ezinjengokungakwazi ukufaka, ukungonelanga kwamanzi, ukungakwazi ukumpompa amanzi, kunye nokonakalisa iqula.Ke ngoko, indlela yokukhetha impompo yequla enzulu ibaluleke kakhulu (1) Uhlobo lwempompo lumiselwa ngokwedayamitha yomthombo kunye nomgangatho wamanzi.Iindidi ezahlukeneyo zeempompo zineemfuno ezithile zobungakanani bomthombo wedayamitha, kwaye ubungakanani obuphezulu bempompo buyakuba ngaphantsi kobubanzi bomthombo we-25 ~ 50mm.Ukuba umngxuma womthombo ugobile, owona mgangatho uphezulu wempompo uyakuba mncinci.Ngamafutshane, impompo

Ilungu lomzimba aliyi kusondela eludongeni lwangaphakathi} lwequla, ukuze iqula lonakaliswe kukungcangcazela kwempompo engenamanzi.(2) khetha ukuhamba kwempompo yequla ngokompompo wamanzi wequla.Iqula ngalinye linemveliso yamanzi yezoqoqosho, kwaye ukuhamba kwempompo kuyakulingana okanye ngaphantsi kwemveliso yamanzi xa umgangatho wamanzi wequla lemoto uhla ukuya kwisiqingatha sobunzulu bamanzi equla.Xa umthamo wokupompa umkhulu kunomthamo wokupompa wequla, uya kubangela ukuwa kunye nokubekwa kodonga lomthombo kunye nokuchaphazela ubomi benkonzo yomthombo;Ukuba umthamo wokupompa uncinci kakhulu, ukusebenza kakuhle kwequla akuyi kuziswa ngokupheleleyo.Ke ngoko, eyona ndlela ilungileyo kukuqhuba uvavanyo lokumpompa kumatshini} kakuhle, kwaye uthathe ubuninzi bemveliso yamanzi enokubonelela ngequla njengesiseko sokukhetha ukuhamba kwempompo yomthombo.Ukuhamba kwempompo yamanzi, kunye nemodeli yophawu

Okanye inombolo ephawulweyo kwingxelo iya koyisa.(3) ngokobunzulu obuwayo bomgangatho wamanzi equla kunye nelahleko yentloko yombhobho wothumelo lwamanzi, misela eyona ntloko ifunekayo yempompo yequla, oko kukuthi, intloko yempompo yequla, elingana nomgama othe nkqo. (intloko yomnatha) ukusuka kwinqanaba lamanzi ukuya kumphezulu wamanzi wetanki yokuphuma kunye nentloko elahlekileyo.Intloko yelahleko idla ngokuba yi-6 ~ 9% yentloko yomnatha, idla ngokuba yi-1 ~ 2m.Ubunzulu bokungena kwamanzi kwesona nqanaba sisezantsi i-impeller yempompo yamanzi kufuneka ibe yi-1 ~ 1.5m.Ubude obupheleleyo benxalenye phantsi kombhobho wempompo abuyi kudlula ubude obuninzi bo} ukungena kwindawo echazwe kwi-pump manual.(4) iimpompo zamaqula anzulu akufuneki zifakelwe amaqula anentlenga yamanzi equlathe amanzi angaphezu kwe-1/10000. Ngenxa yokuba isiqulatho sesanti samanzi omthombo sisikhulu kakhulu, njengaxa sidlula i-0.1%, siya kukhawulezisa ukuguga kwerabha yokuthwala, kubangela ukungcangcazela kwempompo yamanzi kunye nokunciphisa ubomi benkonzo yempompo yamanzi.
