Njengoninzi lwempompo, impompo yecentrifugal iguqula amandla oomatshini ukusuka kwimoto iye kumandla ombane ohambahambayo; amanye amandla aya kwi-kinetic energy ye-fluid motion, kwaye amanye abe ngamandla anokubakho, amelwe luxinzelelo lwamanzi okanye ngokuphakamisa ulwelo ngokuchasene nomxhuzulane ukuya kwinqanaba eliphezulu.
Ngolwazi oluthe kratya malunga nesi sihloko, bona ICentrifugal compressor.
Ukugqithiswa kwamandla ukusuka kukujikeleza koomatshini kwesixhobo sokuhambisa kunye noxinzelelo lolwelo kuhlala kuchazwa ngokwamandla e-centrifugal, ngakumbi kwimithombo yakudala ebhaliweyo ngaphambi kwento yangoku yamandla e-centrifugal njengamandla obuxoki kwisakhelo sesalathiso esijikelezayo icaciswe kakuhle. Umxholo wamandla e-centrifugal awunyanzelekanga ukuba uchaze isenzo sepompo ye-centrifugal.
Kwimpompo yanamhlanje ye-centrifugal pump, uninzi lokuguqulwa kwamandla kungenxa yamandla angaphandle aphembelela iincakuba ezigobileyo ukuba zingene kulwelo. Ngokungaguquguqukiyo, amanye amandla nawo atyhala ulwelo kwisindululo setyhula, kwaye esi sishukumiso setyhula sinokudlulisela amandla kunye nokwandisa uxinzelelo kwindawo ephumayo. Ubudlelwane phakathi kwezi ndlela buchaziwe, kunye nengqondo edibeneyo yokuxuba amandla e-centrifugal njengokuba kwaziwa ngelo xesha, kwinqaku le-1859 elalikwiimpompo ze-centrifugal, ngaloo ndlela ukufika ngendlela elula kunaleyo inikwe nje umbono jikelele wendlela yokusebenza I-whirlpool yangaphandle ekuphuculeni ukusebenza kakuhle kwempompo ye-centrifugal, kufanelekile kuphela ukuqaphela ukuba ubunzima bamanzi obujikeleza kwigumbi le-whirlpool, ukujikeleza isangqa sevili, kufuneka kunyanzelise amandla e-centrifugal, kwaye la mandla e-centrifugal ngokulula kufuneka ukuba izongeze kumandla angaphandle aveliswe ngaphakathi kwevili; okanye, ngamanye amagama, ukuya kunyusa amandla okupompa ivili. Amandla angaphandle aveliswe ngaphakathi kwevili kufuneka aqondwe njengokuveliswa ngokupheleleyo ngamandla aphakathi kwe-centrifugal ukuba iivenkile zevili zilungile kwaye ziradi; kodwa ukuba zigobile, njengoko kuqhele ukwenzeka njalo, amandla angaphandle aveliswa ngenxalenye yamandla e-centrifugal force, kwaye ngokuyinxenye asetyenziswa ziinqwelo emanzini njengenxalenye yomsinga woxinzelelo lwe-oblique, ethi, ngenxa Ukuthobela iradiyasi, zisebenza emanzini njengoko ephumela ngaphandle ecaleni kwazo. Kule nto kulungile ukuba uqaphele ukuba ngelixa ubungakanani bamanzi enziwe ukuba agqithe kwimpompo enikiweyo ene-vanes egophileyo eguquguqukayo kulonwabo, ubuncinci ubuninzi buya buba ngaphezulu kokukhona amandla aya kuveliswa ngaphakathi kwevili ukunyanzela ukuphuma kwamanzi Ibe kuphela ngamandla okucoca amandla amakhulu, kwaye ngakumbi impompo iya kuba yile nto igama eliqhelekileyo elinikwe yona inokubonakala ngathi iyimpompo eyi-centrifugal. Xa, nangona kunjalo, impompo ye-centrifugal ene-vanes egobele ngasemva kwiifom njengoko zisetyenziswa kwimizekelo eyakhiwe kakuhle yomatshini, iqhutywa ngesantya esingaphezulu kakhulu kwesoyimfuneko sokoyisa uxinzelelo lwamanzi, kwaye ibangele ukuphakamisa okanye ukuqhubela phambili Ukuqala, icandelo lomsinga wamandla asetyenziswa emanzini ziivensi liya kuqapheleka, kwaye amanzi ashiya ujikelezo lwevili aya kuba nesantya esingaphantsi kwesokujikeleza kwevili kwinqanaba elinexabiso elibalulekileyo ukuziqhelanisa.
Isiteyitimenti esithi “ubuninzi bamanzi… kumele ukuba basebenzise amandla okwexeshana” siyatolikwa ngokwamandla asebenzayo esentrifugal-amandla ayisiyonto yangaphandle emanzini, kodwa ingamandla angaphandle asebenza ngamanzi, kwimpompo yezindlu. (ivolthi) nasemanzini kumbhobho wokuphuma. Uxinzelelo lweplawo lubonisa uxinzelelo olusebenzisa amandla e-centripetal ajika indlela yamanzi ukuba ihambe ngokujikeleza ngaphakathi kwimpompo (kwisithuba esingaphandle kwempompo, i-whirlpool yangaphandle njengoko umbhali eyibiza njalo). Kwelinye icala, ingxelo yokuba "amandla angaphandle aveliswe ngaphakathi kwevili kufuneka aqondwe njengokuveliswa ngokupheleleyo ngamandla aphakathi kwe-centrifugal" aqondwa ngcono ngokubhekisele kumandla e-centrifugal njengamandla ayintsomi kwisakhelo sereferensi ujikelezisa impeller; eyona mikhosi isemanzini ingaphakathi, okanye icentripetal, kuba ulwalathiso lwamandla kufuneka enze ukuhamba kwamanzi kwizangqa. Lo mkhosi unikezelwa ngoxinzelelo lwegradi olusetwe kukujikeleza, apho uxinzelelo ngaphandle, eludongeni lwevolute, lunokuthathwa njengamandla e-centrifugal asebenzayo. Oku kuqhelekile ekubhalweni kwenkulungwane ye-19 nasekuqaleni kwekhulu lama-20, ukuxuba le mibono yamandla e-centrifugal kwinkcazo engacwangciswanga yeziphumo ezinjezo kwimpompo ye-centrifugal.
