Ungakhetha kanjani phakathi kwamaphampu avundlile naqondile kanye nezinhlelo zamanzi omlilo wamapayipi?
Iphampu yamanzi omliloUkucatshangelwa
Iphampu ye-centrifugal efanele ukusetshenziswa kwamanzi omlilo kufanele ibe nejika eliphansi lokusebenza.Iphampu elinjalo lilingana nesidingo esikhulu kakhulu somlilo omkhulu esitshalweni.Lokhu kuvame ukuhumusha emlilweni omkhulu endaweni enkulu yesitshalo.Lokhu kuchazwa umthamo olinganiselwe kanye nenhloko elinganiselwe yesethi yephampu.Ukwengeza, ipompo yamanzi omlilo kufanele ibonise amandla okugeleza okukhulu kune-150% yomthamo wayo olinganiselwe ngaphezu kwe-65% yekhanda layo elilinganiselwe (ingcindezi yokukhishwa).Eqinisweni, amaphampu amanzi omlilo akhethiwe adlula amanani ashiwo ngenhla.Kube namaphampu amaningi amanzi omlilo akhethwe kahle anamajika ayisicaba anganikeza ngaphezu kwe-180% (noma ngisho ne-200%) yomthamo olinganisiwe ekhanda kanye nangaphezulu kuka-70% wengqikithi yekhanda elilinganiselwe.
Amathangi amanzi omlilo amabili kuya kwamane kufanele ahlinzekwe lapho umthombo oyinhloko wamanzi omlilo ukhona.Umthetho ofanayo uyasebenza kumaphampu.Amaphampu amanzi omlilo amabili kuya kwamane kufanele ahlinzekwe.Ukuhlelwa okujwayelekile yilokhu:
● amaphampu amanzi amabili omlilo ashayelwa yinjini (eyodwa esebenzayo neyodwa ebekwe eceleni)
● amaphampu amanzi omlilo ashayelwa injini kadizili (eyodwa esebenzayo neyodwa ebekwe eceleni)
Enye inselele ukuthi amaphampu amanzi omlilo angase angasebenzi isikhathi eside.Kodwa-ke, ngesikhathi somlilo, ngamunye kufanele aqalwe ngokushesha futhi aqhubeke nokusebenza kuze kube yilapho umlilo ucisha.Ngakho-ke, amalungiselelo athile ayadingeka, futhi iphampu ngayinye kufanele ihlolwe ngezikhathi ezithile ukuze kuqinisekiswe ukuqala okusheshayo nokusebenza okuthembekile.
Amaphampu Avundlile vs. Amaphampu Aqondile
Amaphampu e-centrifugal avundlile awuhlobo olukhethwa ngabasebenzisi abaningi lwephampu yamanzi omlilo.Isizathu esisodwa salokhu ukudlidliza okuphakeme uma kuqhathaniswa kanye nesakhiwo semishini esingaba sengozini samaphampu amakhulu aqondile.Kodwa-ke, amaphampu amile, ikakhulukazi amaphampu ohlobo lwe-turbine eqondile, kwesinye isikhathi asetshenziswa njengamaphampu amanzi omlilo.Ezimweni lapho ukunikezwa kwamanzi kutholakala ngaphansi komugqa omaphakathi we-flange, futhi ingcindezi inganele ukuze kuyiswe amanzi epompo lamanzi omlilo, isethi yephampu yohlobo lwe-vertical-shaft turbine ingase isetshenziswe.Lokhu kusebenza ngokukhethekile lapho amanzi aphuma emachibini, emachibini, emithonjeni, noma olwandle ezosetshenziswa njengamanzi omlilo (njengomthombo oyinhloko noma njengesipele).
Kumaphampu aqondile, ukucwiliswa kwezitsha zepompo kuwukucushwa okufanelekile kokusebenza okuthembekile kwepompo yamanzi omlilo.Uhlangothi lokumunca lwephampu eqondile kufanele lubekwe lujule emanzini, futhi ukucwiliswa kwe-impeller yesibili ukusuka phansi kwesitsha sepompo kufanele kube ngaphezu kwamamitha ama-3 lapho iphampu isebenza ngesilinganiso sayo esiphezulu sokugeleza okungenzeka.Ngokusobala, lokhu ukucushwa okuqondile, futhi imininingwane yokugcina kanye nokucwiliswa emanzini kufanele kuchazwe icala ngalinye, ngemva kokubonisana nomkhiqizi wephampu, iziphathimandla zendawo zomlilo kanye nabanye ababambiqhaza.
Kube nezimo eziningana zokudlidliza okuphezulu kumaphampu amakhulu amanzi omlilo aqondile.Ngakho-ke, izifundo eziguquguqukayo ngokucophelela nokuqinisekiswa kuyadingeka.Lokhu kufanele kwenziwe kuzo zonke izici zokuziphatha okuguquguqukayo.
