Umpompo wokuzibamba yimpompo ye-centrifugal yesakhiwo esikhethekileyo esinokusebenza ngokuqhelekileyo ngaphandle kokuzaliswa kwakhona emva kokuzaliswa kokuqala.Ingabonwa ukuba impompo yokuzimela yimpompo ekhethekileyo ye-centrifugal.Impompo yokuzenzela yaziwa ngokuba yimpompo ye-self-priming centrifugal.

Umgaqo wokuzingca

Ipompo yokuzenzela i-self-priming ingaba yi-self-priming, kwaye isakhiwo sayo ngokwemvelo sineempawu ezikhethekileyo.Izibuko lokufunxa lempompo yokuziqala lingaphezulu kwe-impeller.Emva kokuvalwa ngalunye, amanye amanzi anokugcinwa kwimpompo kwisiqalo esilandelayo.Nangona kunjalo, ngaphambi kokuqalisa kokuqala, kuyimfuneko ukongeza ngesandla ngokwaneleyo amanzi okuzikhupha kwimpompo, ukwenzela ukuba ininzi ye-impeller ifakwe emanzini.Emva kokuba ipompo iqaliswe, amanzi kwi-impeller achaphazeleka ngamandla e-centrifugal kwaye ageleza kumda wangaphandle we-impeller, apho adibana khona negesi kumda wangaphandle we-impeller.Ukudibanisa ukwenza isangqa somxube we-foam-shaped gas-shaped gas-water, i-foam belt ichithwa ngokuhlukana, ukwenzela ukuba umxube wegesi-manzi ungene kwigumbi lokuhlukanisa i-gas-water ngokusebenzisa umbhobho wokusabalalisa.Ngeli xesha, ngenxa yokunyuka ngokukhawuleza kwendawo yokudlula amanzi, izinga lokuhamba liyancipha ngokukhawuleza., ukuxinana kwerhasi kuncinci, iyabaleka emanzini kwaye ikhutshwe yimpompo yoxinzelelo lwempompo, ukuxinana kwamanzi kukhulu, kwaye iwela phantsi kwegumbi lokwahlula amanzi egesi, kwaye ibuyela umda wangaphandle we-impeller ngokusebenzisa umngxuma wokubuya kwe-axial, kwaye udibanise negesi kwakhona.Ngomjikelezo oqhubekayo wale nkqubo ingentla, iqondo le-vacuum kumbhobho wokufunxa liya kuqhubeka nokunyuka, kwaye amanzi aya kuhanjiswa aya kuqhubeka nokunyuka kunye nombhobho wokufunxa.Xa umpompo uzaliswe ngokupheleleyo ngamanzi, umpompo uya kungena kwisimo esiqhelekileyo sokusebenza kwaye ugqibezele inkqubo yokuzimela.

Isiphelo esibanzi

Ipompo yokuzimela ngokwayo iyipompo ye-centrifugal enesakhiwo esikhethekileyo.Emva kokuba ulwakhiwo lwempompo ye-self-priming luphuculwe, ukusebenza kwamanzi kubhetele kwaye ukufunxa kwamanzi kulungeleka ngakumbi.Nangona impompo ye-centrifugal ngokubanzi ine-stroke yokufunxa, ukufunxwa kwamanzi akulula njengaleyo yempompo eziziqalayo, kwaye i-stroke yokufunxa ayikho phezulu njengaleyo yempompo ezizimeleyo.Ngokukodwa i-jet self-priming pump, i-suction stroke inokufikelela kwi-8-9 yeemitha.Impompo ye-centrifugal jikelele ayikwazi.Kodwa ngokusetyenziswa ngokubanzi, akukho mfuneko yokukhetha ngamabomu impompo yokuzenzela, khetha nje ipompo ye-centrifugal jikelele.
