Monga mapampu ambiri, pampu ya centrifugal amasintha mphamvu zamagetsi kuchokera pagalimoto kupita ku mphamvu yamadzimadzi oyenda; Ena mwa mphamvu amapita ku kayendedwe ka kayendedwe kake kamadzimadzi, ndipo ena mphamvu zowoneka, zoyimiriridwa ndi kuthamanga kwamadzimadzi kapena kukweza madziwo motsutsana ndi mphamvu yokoka.
Kuti mumve zambiri pamutuwu, onani Centrifugal compressor.
Kutumiza kwa mphamvu kuchokera pakusinthasintha kwamphamvu kwa zoyendetsa mpaka kuyenda ndi kuthamanga kwa madzimadzi kumafotokozedwera malinga ndi mphamvu ya centrifugal, makamaka m'mabuku akale omwe adalembedwa lisanachitike lingaliro lamakono la mphamvu ya centrifugal ngati mphamvu yongopeka yomwe ikuzungulira zomveka bwino. Lingaliro la mphamvu ya centrifugal sikofunikira kwenikweni kuti lifotokozere zomwe mpope wa centrifugal amachita.
Mu mpope wamakono wa centrifugal, kutembenuka kwamphamvu kwakukulu kumachitika chifukwa cha mphamvu yakunja yomwe masamba opindika othamangitsira madzi. Nthawi zonse, mphamvu zina zimakankhiranso zakumwa kuti zizizungulira, ndipo kuyenda uku kumatha kuperekanso mphamvu ndikuwonjezera kukakamizidwa kubuloko. Chiyanjano pakati pa njirazi chidafotokozedwa, ndi lingaliro losakanikirana la mphamvu ya centrifugal yomwe imadziwika kuti nthawiyo, mu nkhani ya 1859 yokhudza mapampu a centrifugal, potero kuti ifike ndi njira yosavuta kuposa yomwe idangoperekedwa palingaliro la momwe magwiridwe antchito ya whirlpool yakunja pakukonza magwiridwe antchito a pampu wa centrifugal, ndikofunikira kudziwa kuti kuchuluka kwa madzi ozungulira mchipinda cha whirlpool, mozungulira kuzungulira kwa gudumu, kuyenera kukhala ndi mphamvu ya centrifugal, ndikuti mphamvu ya centrifugal iyi ayenera kuyerekezedwa ndi mphamvu yakunja yomwe imapangidwa mkati mwa gudumu; kapena, mwanjira ina, kupita kukakulitsa mphamvu yakupopa kwa gudumu. Mphamvu zakunja zomwe zimapangidwa mkati mwa gudumu ziyenera kumveka kuti zimapangidwa kwathunthu ndi mphamvu ya centrifugal ngati ma vanes a wheel amakhala owongoka komanso ozungulira; koma ngati atapindika, monga momwe zimakhalira nthawi zambiri, mphamvu yakunja imapangidwa mwa mphamvu ya centrifugal, ndipo pang'ono ndi pang'ono imagwiritsidwa ntchito ndi malo opita kumadzi ngati gawo lalikulu lamavuto oblique, omwe, chifukwa cha obliquience kwa utali wozungulira, amapaka madzi pamene amayenda panja limodzi nawo. Pankhaniyi ndibwino kudziwa kuti ngakhale kuchuluka kwa madzi opangidwa kuti adutse pampu yoperekedwa ndi ma vanes okhota amasinthasintha mosangalatsa, zocheperako kuchuluka kwake kumakhala kokwanira kwambiri mphamvu yomwe imapangidwa mkati mwa gudumu yoyendetsera madzi kunja Kukhala mphamvu ya centrifugal, ndipo mpope udzakhala wochulukira kuposa momwe dzinalo limaperekedwera kwa iwo lingawoneke ngati likutanthauza pampu ya centrifugal. Pomwe, komabe pampu wa centrifugal wokhala ndi ma vanes wopindika kumbuyo m'njira zomwe zimagwiritsidwa ntchito pazitsanzo zomangidwa bwino za makina, imayendetsedwa mwachangu kwambiri kuposa zomwe zimafunika kungothana ndi kuthamanga kwa madzi, ndikupangitsa kukweza kapena kuyendetsa kuti ayambe, chigawo champhamvu champhamvu chomwe chimagwiritsidwa ntchito pamadzi ndi zithunzicho chidzakhala chachikulu, ndipo madzi omwe akuchoka kuzungulira kwa gudumu amakhala ndi liwiro locheperako pozungulira gawo la gudumu pamlingo wokhala ndi kufunika kwenikweni yesetsani.
Mawu oti "unyinji wa madzi… akuyenera kukhala ndi mphamvu ya centrifugal" ndikumasuliridwa potengera mphamvu yogwira ntchito ya centrifugal-mphamvuyo si mphamvu yakunja pamadzi, koma mphamvu yakunja yogwiritsidwa ntchito ndi madzi, pampope wa nyumba (volute) komanso pamadzi otulutsa chitoliro. Kutulutsa kotulutsaku ndikuwonetsa kukakamiza komwe kumagwiritsa ntchito mphamvu ya centripetal yomwe imakhotetsa njira yamadzi kuti iziyenda mozungulira mkati mwa pampu (m'malo omwe ali kunja kwa impeller, whirlpool yakunja monga wolemba uyu amachitchulira). Kumbali inayi, mawu akuti "mphamvu yakunja yopangidwa mkati mwa gudumu iyenera kumvedwa kuti yakhazikitsidwa kwathunthu ndi mphamvu ya centrifugal" imamveka bwino ponena za mphamvu ya centrifugal ngati mphamvu yopeka mu chimango cha mawu a onsewo impeller; mphamvu zenizeni pamadzi zili mkati, kapena centripetal, chifukwa ndiye malangizo a mphamvu akuyenera kupangitsa madzi kuyenda mozungulira. Mphamvu imeneyi imaperekedwa ndi kupsyinjika komwe kumayendetsedwa ndi kusinthasintha, komwe kukakamiza kunjako, kukhoma kwa volute, kumatha kutengedwa ngati mphamvu yothandizanso ya centrifugal. Izi ndizofanana ndikulemba kwa 19th komanso koyambirira kwa zaka za zana la makumi awiri, kusakaniza malingaliro awa a mphamvu ya centrifugal pamawu osamveka bwino azotsatira monga zomwe zili mu pump centrifugal.
