Indlela yokwahlula phakathi komphunga ophuphumayo kunye nomphunga oshushu kakhulu
Ukubeka ngokulula, ijenereyitha yomphunga yibhoyila yoshishino efudumeza amanzi ukuya kumlinganiselo othile ukuvelisa umphunga wobushushu obuphezulu. Abasebenzisi banokusebenzisa umphunga kwimveliso yeshishini okanye ukufudumeza njengoko kufuneka.
Iijenereyitha zomphunga zinexabiso eliphantsi kwaye kulula ukuzisebenzisa. Ngokukodwa, iijenereyitha zomphunga wegesi kunye neejenereyitha zombane zombane ezisebenzisa amandla acocekileyo zicocekile kwaye azinangcoliseko.
