Impompo yamanzi anzulu yimpompo ye-centrifugal ethe nkqo, enokuphakamisa amanzi kwimithombo enzulu. Ngokwehla kwenqanaba lamanzi aphantsi komhlaba, iimpompo ezinzulu zamanzi zisetyenziswa kakhulu kuneempompo ze-centrifugal ngokubanzi. Nangona kunjalo, ngenxa yokhetho olungalunganga, abanye abasebenzisi baneengxaki ezinje ngokungakwazi ukufaka, ukungonelanga kwamanzi, ukungakwazi ukumpompa amanzi, nokonakalisa iqula. Ke ngoko, ukukhetha umpompo wamanzi anzulu kubaluleke kakhulu. Iindidi ezahlukeneyo zeempompo zineemfuno ezithile kubungakanani bedayimani elungileyo, kwaye ubuninzi bempawu zempompo ziya kuba ngaphantsi kobubanzi be-25 ~ 50mm. Ukuba umngxuma wequla ujijekile, ubukhulu becala lobungakanani bempompo buya kuba buncinci. Ngamafutshane, impompo

Ilungu lomzimba aliyi kusondela eludongeni lwangaphakathi lwequla, ukuze iqula lonakaliswe kukungcangcazeleka kwempompo engena manzi. (2) khetha ukuhamba kwempompo yequla ngokutsho kwemveliso yamanzi. Iqula ngalinye linemveliso efanelekileyo ngokwezoqoqosho, kwaye ukuhamba kwempompo kuya kulingana okanye kungaphantsi kokukhutshwa kwamanzi xa inqanaba lamanzi emoto liwela kwisiqingatha sobunzulu bamanzi. Xa umthamo wokumpompa ungaphezulu komthamo wokumpompa kwequla, kuya kubangela ukuwa kunye nokubekwa kodonga lwequla kwaye kuchaphazele ubomi benkonzo yequla; Ukuba umthamo wokumpompa mncinci kakhulu, ukusebenza kakuhle kwequla akuyi kuziswa kumdlalo opheleleyo. Ke ngoko, eyona ndlela ilungileyo kukwenza uvavanyo lokumpompa kumatshini} kakuhle, kwaye uthathe esona siphumo siphezulu samanzi esinokubonelelwa liqula njengesiseko sokukhetha ukuhamba kompompo wequla. Ukuhamba kwempompo yamanzi, kunye nemodeli yohlobo

Okanye inani eliphawulwe kwingxelo liya koyisa. (3) ngokobunzulu bokuwa kwenqanaba lamanzi equka kunye nelahleko lwentloko yombhobho wokuhambisa amanzi, misela eyona nto ifunekayo kwimpompo yequla, oko kukuthi, intloko yempompo yequla, elingana nomgama othe nkqo (Intloko yenethi) ukusuka kwinqanaba lamanzi ukuya kumphezulu wamanzi wetanki yokuphuma kunye nentloko elahlekileyo. Intloko yelahleko ihlala i-6 ~ 9% yentloko yomnatha, ihlala i-1 ~ 2m. Ubunzulu bokungena kwamanzi kwinqanaba elisezantsi lokumpompa amanzi kufuneka libe yi-1 ~ 1.5m. Ubude bebonke benxalenye phantsi kwetyhubhu yokumpompa kakuhle abuyi kudlula kubude obuphezulu} bokungena equleni elichaziweyo kwincwadana yempompo. (4) iimpompo zamanzi anzulu akufuneki zifakelwe imithombo enezinto ezinamanzi kakuhle ezigqitha i-1/10000. kubangele ukungcangcazela kwempompo yamanzi kunye nokunciphisa ubomi benkonzo yempompo yamanzi.
