Senzira yekuvhura, kuvhara uye kudzora pombi yekubvisa guruva, vharuvhu yemapuruguru yekufema yakakodzera masisitimu ekubvisa guruva, kubvisa guruva uye kuchengetedza nharaunda mukugadzira simbi, migodhi, simende, indasitiri yemakemikari uye kugadzira magetsi.

Vharuvhu yeshavishavi yekufema inogadzirwa kuita rin'i yekuvhara ine chinhu chimwe chete nemuviri wevharuvhu. Tembiricha yayo inoenderana nesarudzo yezvinhu zvemuviri wevharuvhu, uye kumanikidzwa kwayo kushoma i≤ 0.6MPa. Inowanzo shandiswa kumaindasitiri, simbi, kuchengetedzwa kwezvakatipoteredza uye mamwe mapaipi ekufema uye kudzora kuyerera kwepakati.

Zvinhu zvikuru zvayo ndeizvi:

1. Dhizaini itsva uye ine musoro, chimiro chakasiyana, huremu hwakareruka uye kuvhura nekuvharwa nekukurumidza.

2. Torque diki yekushanda, kushanda kuri nyore, kuchengetedza vashandi uye kugona.

3. Zvinhu zvakakodzera zvinofanira kushandiswa kusangana nezvinodiwa zvekupisa kwakaderera, kwepakati nepakati uye kwepakati uye zvinoparadza.
