Isiseko sokukhethwa kwempompo yodaka kufuneka sisekelwe kwinkqubo yeteknoloji, ukudibanisa neemfuno zokuhambisa amanzi kunye nokuqwalasela iinkalo ezinkulu ezintlanu, ezibandakanya: umthamo wokuhanjiswa kolwelo, intloko yokufakela, iipropati zolwelo, ukulungiswa kwemibhobho kunye neemeko zokusebenza.Ngoku sikunika inkcazo nganye nganye ngokweenkcukacha.
1. Ukuhamba ngenye yeyona datha ibalulekileyo yokusebenza ekukhethweni kwempompo, ehambelana ngqo nomthamo wempompo ye-slurry kunye nomthamo wokuhambisa.Umzekelo ngexesha loyilo lweZiko loYilo lweTrafikhi, impompo iyakwazi ukubala ukuhamba okuthathu: okuqhelekileyo, ubuncinci kunye nobuninzi.Xa ukhetha umpompo, uthatha ukuhamba okuphezulu njengesiseko kwaye uthathela ingqalelo ukuhamba okuqhelekileyo.Ukuba akukho mqukuqelo mkhulu, thatha ngokuphindwe ka-1.1 ukuhamba okuqhelekileyo kwetrafikhi njengowona mkhulu.
2. Ukuphakanyiswa okufunekayo kwesistim yofakelo yidatha yokusebenza ebalulekileyo yokukhetha impompo eludaka.Ngokuqhelekileyo khetha emva kokwandisa ukusetyenziswa ngokubanzi 5% - 10% margin.
3. Iipropati zolwelo, kubandakanywa igama lesixhobo solwelo, iipropathi ezibonakalayo, iipropathi zekhemikhali kunye nezinye iimpawu.Iimpawu ezibonakalayo zibandakanya ukushisa kwe-c density d, i-viscosity u, i-diameter ephakathi kweengqungquthela eziqinileyo kunye nomxholo wegesi, zonke zibandakanya ukunyuswa kwenkqubo, iindidi ze-cavitation margin calculation kunye nepompo efanelekileyo;Iimpawu zeekhemikhali, ikakhulu zibhekisa kwimichiza eyityhefu kunye nolwelo olunomhlwa,Iimpompo zesiXeko esiQhubelayo esiSetyenziswayoeziziziseko eziphambili zokukhetha imathiriyeli yempompo eludaka kunye netywina.Kufuneka ubhekisele kulo lonke ulwazi olungentla.
4. Imeko yoyilo lwemibhobho yenkqubo yesixhobo ibhekiselele ekuthumeleni umgama wokuhanjiswa kolwelo ukuphakama kolwelo ukuthumela ulwelo, icala lokufunxa elifana nenqanaba elisezantsi, elona nqanaba liphezulu ukusuka kwicala kunye nedatha ethile kunye neenkcukacha kunye nobude bombhobho, izixhobo, iinkcukacha zemibhobho, ubungakanani, khangela inkqubo yokubala intloko yekama kunye ne-npsh.
5. Imixholo yeemeko zokusebenza ezininzi, ezifana ukusebenza T yolwelo, umphunga amandla P, uxinzelelo ecaleni suction PS (absolute), uxinzelelo ukusuka kwicala isikhongozeli PZ, ukuphakama, nokuba ubushushu ukusebenza gap okanye okuqhubekayo nokuba indawo yempompo eludaka zilungisiwe okanye shift.
Ukukhethwa kwempompo yodaka yinkqubo enzima, kodwa ibaluleke kakhulu.Ukukhetha imodeli efanelekileyo yepompo ye-slurry ayikwazi nje ukwandisa ngokufanelekileyo ubomi benkonzo kunye nokusebenza kakuhle, kodwa nokunciphisa inani leengxaki ezingeyomfuneko, phantsi kweemeko eziqhelekileyo, i-factory enkulu iya kuba nabasebenzi abaqeqeshiweyo abakhethiweyo,Impompo yoshishino lweBodangoko ekukhethweni kwempompo ye-slurry, kufuneka ukhethe abavelisi abakhulu bokuthembeka, ukwenzela ukuba kuqinisekiswe umgangatho weemveliso.
