Iphampu ye-deep well iyi-pump multistage centrifugal mpo, engaphakamisa amanzi emithonjeni ejulile. Ngokuncipha kwezinga lamanzi angaphansi komhlaba, kusetshenziswa kakhulu amaphampu emithombo ejulile kunamaphampu ajwayelekile we-centrifugal. Kodwa-ke, ngenxa yokukhethwa okungafanele, abanye abasebenzisi banezinkinga ezifana nokungakwazi ukufaka, ukunganele kwamanzi, ukungakwazi ukumpompa amanzi, nokulimaza kahle umthombo. Ngakho-ke, ukuthi ungakhetha kanjani ipompo ejulile yomthombo kubaluleke kakhulu （1) Uhlobo lwepompo lunqunywa kuqala ngokuya ngobubanzi bekhwalithi namanzi. Izinhlobo ezahlukahlukene zamaphampu zinezidingo ezithile zosayizi wobubanzi bomthombo, futhi ubukhulu obukhulu bepompo buzoba ngaphansi kobubanzi bomthombo ongu-25 ~ 50mm. Uma umgodi womthombo usontekile, ubukhulu obukhulu bepompo buzoba buncane. Ngamafuphi, i- pump

Ingxenye yomzimba ngeke ibe seduze nodonga lwangaphakathi} lomthombo, ukuze umthombo uzolimala ngokudlidliza kwepompo elingangeni manzi. (2) khetha ukugeleza kwepompo yomthombo ngokuya ngokukhipha kwamanzi kahle. Umthombo ngamunye unamanzi aphuma kahle ngokwezomnotho, futhi ukugeleza kwepompo kuzolingana noma ngaphansi kokukhipha amanzi lapho izinga lamanzi emthonjeni wehla liye engxenyeni yokujula kwamanzi omthombo. Lapho umthamo wokumpompa ungaphezu komthamo wokumpompa umthombo, uzodala ukuwa nokufakwa kodonga lomthombo futhi kuthinte impilo yokusebenza komthombo; Uma umthamo wokumpompa umncane kakhulu, ukusebenza kahle komthombo ngeke kudlalwe ngokugcwele. Ngakho-ke, indlela engcono kakhulu yokwenza ukuhlolwa kokumpompa emthonjeni} kahle, futhi uthathe okuphuma kwamanzi okuphezulu okunganikezwa ngumthombo njengesisekelo sokukhetha ukugeleza kwepompo yomthombo. Ukugeleza kwepompo yamanzi, nemodeli yomkhiqizo

Noma inombolo ebhalwe esitatimendeni izosebenza. (3) ngokusho kokuwa kwezinga lamanzi emithombo nokulahleka kwekhanda kwepayipi lokudlulisa amanzi, kunquma ikhanda langempela elidingekayo lepompo lomthombo, okungukuthi, ikhanda lepompo lomthombo, elilingana nebanga eliqondile (ikhanda lenetha) kusuka ezingeni lamanzi kuya ebusweni bamanzi wethangi lokuphuma kanye nekhanda elilahlekile. Ikhanda lokulahleka livame ukuba yi-6 ~ 9% yekhanda lenetha, imvamisa i-1 ~ 2m. Ukujula kokungena kwamanzi kwesiteji esiphansi kakhulu sempompo yamanzi kufanele kube yi-1 ~ 1.5m. Ubude obuphelele bengxenye ngaphansi kompompi wepompo kahle abungeqi ubude obude bokufika} kokungena emthonjeni obalulwe kumanuwali yepompo. (4) amaphampu emithombo ejulile akufanele afakwe emithonjeni enesiqu samanzi sedlula i-1 / 10000. Ngoba okuqukethwe yisihlabathi samanzi emthonjeni kukhulu kakhulu, okufana nokuthi Lapho kudlula u-0.1%, kuzosheshisa ukugqokwa kokuthwala injoloba, kubangele ukudlidlizela kompompi wamanzi futhi kufushanise impilo yenkonzo yepompo yamanzi.
