Njengamaphampu amaningi, ipompo ye-centrifugal iguqula amandla womshini ukusuka emotweni iye emandleni oketshezi oluhambayo; amanye amandla angena kumandla we-kinetic wokunyakaza ketshezi, kanti amanye angena emandleni angaba khona, amelwe yingcindezi yoketshezi noma ngokuphakamisa uketshezi lubhekane namandla adonsela phansi lube sezingeni eliphakeme.
Ngemininingwane engaphezulu ngalesi sihloko, bona iCentrifugal compressor.
Ukudluliswa kwamandla kusuka ekuphendukeni kwemishini yokuphehla kuya ekunyakazeni nasekucindezelweni koketshezi kuvame ukuchazwa ngamandla we-centrifugal, ikakhulukazi emithonjeni emidala ebhalwe ngaphambi komqondo wanamuhla wamandla we-centrifugal njengamandla aqanjiwe kuhlaka lwesethenjwa olujikelezayo icaciswe kahle. Umqondo wamandla we-centrifugal awudingeki empeleni ukuchaza isenzo sephampu ye-centrifugal.
Epompo yesimanjemanje ye-centrifugal, iningi lokuguqulwa kwamandla kungenxa yamandla angaphandle amachashazi empephele agobile anika uketshezi. Ngaso sonke isikhathi, amanye amandla abuye adudule uketshezi lube yindilinga eyindilinga, futhi lokhu kunyakaza okuyindilinga nakho kungadlulisa amandla athile futhi kwandise ingcindezi lapho iphuma khona. Ubudlelwano phakathi kwalezi zinqubo buchaziwe, ngomqondo ohlanganisiwe ojwayelekile wamandla we-centrifugal owaziwa njengaleso sikhathi, ku-athikili ka-1859 emaphampu we-centrifugal, ngaleyo ndlela afike ngendlela elula kunaleyo enikezwe embonweni ojwayelekile wemodi yesenzo kwe-whirlpool yangaphandle ekuthuthukiseni ukusebenza kahle kwepompo ye-centrifugal, kudingekile kuphela ukubheka ukuthi ubukhulu bamanzi ajikeleza egumbini le-whirlpool, ukuzungeza isondo lesondo, kumele kube namandla we-centrifugal, nokuthi lo mandla we-centrifugal kulindeleke ukuthi izithasisele emandleni angaphandle akhiwe ngaphakathi kwesondo; noma, ngamanye amagama, ukuya ukwandisa amandla wokumpompa kwesondo. Amandla angaphandle akhiqizwe ngaphakathi kwesondo kufanele aqondwe njengakhiqizwa ngokuphelele ngamandla aphakathi kwe-centrifugal uma ama-vanes wesondo eqondile futhi eyi-radial; kodwa uma egobile, njengoba kuvame ukwenzeka, amandla angaphandle akhiqizwa ngokwengxenye yamandla we-centrifugal, futhi ngokwengxenye asetshenziswa ngamanoni emanzini njengengxenye yomsinga wengcindezi ye-oblique, okuthi, ngenxa obliquity engqamuzaneni, zisebenza emanzini njengoba ehamba ngaphandle eceleni kwazo. Kule ndaba, kuhle ukubona ukuthi ngenkathi inani lamanzi elenziwe ukuba lidlule empompini elinikeziwe elinamaveni agobile liguquguquka ngokuphelele ebumnandini, uma ubuncane besibalo bucishe bube namandla amakhulu akhiqizwa ngaphakathi kwesondo lokuqhubela amanzi ngaphandle iba ngamandla we-centrifugal kuphela, futhi cishe kakhulu lapho ipompo izoba yilokho igama elijwayele ukunikezwa lona kungabonakala likhombisa-ipompo ye-centrifugal kuphela. Lapho, nokho, ipompo ye-centrifugal enamaveni igobile ibheke emuva ngalezo zindlela ezisetshenziswa kakhulu ezibonelweni ezakhiwe kahle zomshini, iqhutshwa ngejubane elingaphezulu kakhulu kwalokho okudingekayo ukuze kunqotshwe ingcindezi yamanzi, futhi kubangele ukuphakamisa noma ukuqhuma ukuqala, ingxenye yomsakazo yamandla asetshenziswa emanzini yizikhala ezinkulu, futhi amanzi ashiya umjikelezo wesondo azoba nejubane elingaphansi kwalelo lokuzungezwa kwesondo ngezinga elithile ngokubaluleka kwangempela umkhuba.
Isitatimende esithi “isisindo samanzi… kumele sisebenzise amandla amakhulu” siyachazeka ngokwamandla asebenzayo we-centrifugal-amandla awewona amandla angaphandle emanzini, kepha kunalokho amandla angaphandle asebenza ngamanzi, ezindlini zepompo (i-volute) nasemanzini epayipini lokuphuma. Ingcindezi yokuphuma ibonisa ingcindezi esebenzisa amandla we-centripetal ajika indlela yamanzi ukuze ihambe isiyingi ngaphakathi kwepompo (esikhaleni ngaphandle nje kwempepho, i-whirlpool yangaphandle njengoba lo mbhali eyibiza kanjalo). Ngakolunye uhlangothi, isitatimende sokuthi "amandla angaphandle akhiqizwe ngaphakathi kwesondo kufanele aqondwe njengokhiqizwa ngokuphelele ngamandla aphakathi kwe-centrifugal" siqondwa kangcono ngokwamandla we-centrifugal njengamandla aqanjiwe ohlakeni lokubhekisa impeller ejikelezayo; amandla angempela asemanzini angaphakathi, noma i-centripetal, ngoba lokho kuyisiqondiso samandla okudinga ukwenza amanzi ahambe ngemijikelezo. La mandla ahlinzekwa yi-gradient yengcindezi esethwe ukujikeleza, lapho ingcindezi engaphandle, odongeni lwevolute, ingathathwa njengamandla we-centrifugal asebenzayo. Lokhu kujwayelekile ekubhalweni kwekhulu le-19 nasekuqaleni kwekhulu lama-20, ukuxuba le mibono yamandla we-centrifugal ezincazelweni ezingahlelekile zemiphumela efana naleyo esepompini ye-centrifugal.
