Uma ufuna ukwazi konke mayelana iphampu ye-turbine enezigaba eziningi , kubalulekile futhi ukwazi ngoketshezi noketshezi oluluhambisayo.

Uketshezi kanye Noketshezi

Kunomehluko obalulekile phakathi koketshezi noketshezi. Uketshezi lubhekisela kunoma iyiphi into ephakathi kwezigaba eziqinile negesi. Ukuthi into ethile isesimweni soketshezi kuncike ezingeni lokushisa kanye nengcindezi eyitholayo, kanye nezici zangaphakathi zento ngokwayo.

Uketshezi yinoma iyiphi into ekwazi ukugeleza ngokuqhubekayo futhi ekwazi ukwenza noma yikuphi ukuma kwesiqukathi esikuqukethe. Nakuba lokhu kuchaza kahle uketshezi, kungasetshenziswa futhi ukuchaza amagesi. Ngamanye amazwi, zonke izinto eziwuketshezi ziwuketshezi, kodwa akuwona wonke uketshezi olusesimweni soketshezi. Ngakho-ke, ngokuvamile, lapho igama elithi "fluid" lisetshenziswe ku- iphampu ye-turbine enezigaba eziningi, ibhekisela oketshezini, njengoba amaphampu engaklanyelwe ukuthutha amagesi.

Uketshezi lunezinto ezibonakalayo ezisemqoka ezidinga ukucatshangelwa ekumpompeni izicelo, okuyi-viscosity, ukuminyana, kanye nomfutho womhwamuko (umfutho wokuhwamuka). Lezi zakhiwo zibalulekile ekuqondeni ukuthi uketshezi luziphatha kanjani nokuthi iyiphi iphampu elulungele kangcono.

I-viscosity isho ukumelana koketshezi ukuze lugeleze, noma ukuthi uketshezi "lunamathela" kangakanani. Lokhu kuzothinta izinga lokugeleza, ikhanda eliphelele, ukusebenza kahle, namandla wephampu ye-turbine eqondile yezigaba eziningi.

Ukuminyana kusho ubuningi bento equkethwe kuvolumu ethile. Ekumpompeni, kuvame ukubizwa ngokuthi ukuminyana okuhlobene (i-gravity ethize), okuyisilinganiso sokuminyana kwento nokuminyana kwamanzi ezingeni lokushisa elithile. Ukuminyana kanye namandla adonsela phansi athile kuyadingeka ukuze kunqunywe amandla adingekayo ukuze kuhanjiswe uketshezi olulodwa kolunye.

Umfutho womhwamuko umfutho lapho uketshezi luqala ukuhwamuka (ukuhwamuka), futhi kubalulekile ukuqapha lokhu ohlelweni lwephampu. Uma ingcindezi empompini iphansi kunomfutho we-vaporization we-liquid, i-cavitation ingenzeka.

Ukuqonda umehluko phakathi koketshezi noketshezi nendlela uketshezi oluziphatha ngayo kubalulekile emsebenzini wephampu ye-turbine eqondile yezigaba eziningi.
