Chikamu Chimwe CheteVharuvhu yebhora reDBB trunnion Inopa mavharuvhu maviri uye inobuda ropa muvharuvhu imwe chete. Maitiro aya anogona kuparadzanisa mapaipi kumativi ese evharuvhu kuti abudise/abudise ropa muvharuvhu iri pakati pezvigaro.
Kushandisa sisitimu yevharuvhu ine mavharuvhu maviri uye inobuda ropa uchienzaniswa nemavharuvhu matatu akasiyana kunochengetedza nguva yekuisa, huremu hwemasisitimu epombi, nenzvimbo. Dhizaini iyi ine zvakanakirawo pakushanda,
- Kune nzira shoma kwazvo dzinogona kudonha mvura mukati mechikamu chemapaipi ane mabhuroko maviri uye ropa rakawanda.
- Zvikamu zvese zvevharuvhu zvakachengetwa muyuniti imwe chete, nzvimbo inodiwa pakuiswa kwayo inoderedzwa zvakanyanya zvichiita kuti pave nenzvimbo yezvimwe zvidimbu zvemidziyo inokosha.
- Nguva pfupi yekubuda kwemvura inodiwa.
