Ungayikhetha kanjani phakathi kwamaphampu avundlile ne-vertical nezinhlelo zamanzi omlilo wepayipi?
Iphampu yamanzi yomliloUkucatshangelwa
Iphampu ye-centrifugal efanelekile ukuthola izicelo zamanzi omlilo kufanele ibe nejika lokusebenza eliyisicaba. Iphampu enjalo ilinganiselwe isidingo esikhulu kunazo zonke somlilo omkhulu esitshalweni. Lokhu kuvame ukuhumusha ngomlilo omkhulu ophikweni olukhulu lwesitshalo. Lokhu kuchazwa umthamo olinganiselwe kanye nekhanda elilinganiselwe lesethi yepompo. Ngaphezu kwalokho, iphampu yamanzi yomlilo kufanele ikhombise amandla okugeleza kwezinga elikhudlwana kune-150% yomthamo wayo olinganiselwe nge-65% yekhanda lawo alinganiselwe (ingcindezi yokukhipha). Ekusebenzeni, amaphampu omlilo akhethiwe adlula amanani ashiwo ngenhla. Kube khona amaphampu amaningi akhethwe kalula omlilo anama-curve athambile anganikeza ngaphezulu kwama-180% (noma angama-200%) womthamo olinganiselwe ekhanda nangaphezulu kwama-70% ekhanda elilinganiselwe eliphelele.
Kufanele kuhlinzekwe amathangi amanzi amabili kuya amane. Umthetho ofanayo usebenza ngamaphampu. Kufanele kunikezwe amaphampu wamanzi amabili kuya amane. Ilungiselelo elijwayelekile yile:
● Amaphampu omlilo adonswa izimoto amabili aqhutshwa ngogesi (okukodwa nokubekwe eceleni)
● Amaphampu amabili wedizili aqhutshwa amaphampu omlilo aqhutshwa izinjini (okukodwa nokubekwe eceleni)
Inselelo eyodwa ukuthi amaphampu wamanzi omlilo angeke asebenze isikhathi eside. Kodwa-ke, ngesikhathi somlilo, yilowo nalowo kufanele aqalwe ngokushesha futhi aqhubeke nokusebenza kuze kube yilapho umlilo ucishiwe. Ngakho-ke, ukuhlinzekelwa okuthile kuyadingeka, futhi iphampu ngalinye kufanele lihlolwe ngezikhathi ezithile ukuqinisekisa ukuqala okusheshayo nokusebenza okuthembekile.
Amaphampu ovundlile vs vs mpo mpo mpompi
Amaphampu we-Horizontal Centrifugal abaluhlobo abaningi abasebenza ngokusebenza kwamaphampu omlilo. Isizathu sokuqala salokhu ukudlidliza okuphezulu okuphezulu kanye nesakhiwo esisengozini yamaphampu amakhulu mpo. Kodwa-ke, amaphampu aqonde mpo, ikakhulukazi amaphampu we-tertical-shaft turbine-hlobo nohlobo, kwesinye isikhathi asetshenziswa njengamaphampu wamanzi omlilo. Ezimweni lapho ukuhlinzekwa kwamanzi kutholakala ngaphansi komugqa we-cropengeli Center, futhi ingcindezi inganele ngokuthola amanzi ephampu yamanzi yomlilo, kusethi yepampu empompi-shaft turbine-uhlobo. Lokhu kusebenza ngokukhethekile lapho amanzi avela emachibini, amachibi, amachibi, noma ulwandle bekuzosetshenziswa njengamanzi omlilo (njengomthombo oyinhloko noma njengesipele).
Ngamaphampu mpo, ukuhanjiswa kwezitsha zepompo ukucushwa okuhle kokusebenza okuthembekile kwepompo yamanzi omlilo. Uhlangothi lwephampu mpo kufanele lubekwe ekujuleni kwamanzi, futhi ukuhanjiswa kwesikhumulo sesibili kusuka phansi kwesitsha sepompo kufanele kube ngaphezu kwamamitha ayi-3 lapho impompo isebenza ngenani layo lokugeleza eliphakeme. Ngokusobala, lokhu ukucushwa okuhleliwe, futhi imininingwane yokugcina kanye nokuzithoba kufanele kuchazwe icala ngecala, ngemuva kokubonisana nomenzi wepompo, ababambiqhaza bendawo nabanye ababambe iqhaza.
Kube nezimo eziningana zokudlidliza okuphezulu emaphampu amakhulu omlilo amile. Ngakho-ke, izifundo ezinamandla ngokucophelela nokuqinisekiswa kuyadingeka. Lokhu kufanele kwenziwe ngazo zonke izici zokuziphatha okunamandla.
