Miedzo yevharuvhu inoitwa kuti ione uye kuve nechokwadi kuti mavharuvhu akakodzera kufekitori kushanda Mamiriro.
Kune mhando dzakasiyana dzebvunzo dzinoitwa muvharuvhu.Haisi yese miedzo inofanirwa kuitwa muvharuvhu.Mhando dzebvunzo uye bvunzo dzinodiwa kumhando dzevharuvhu dzakanyorwa patafura inoratidzwa pazasi:
Mvura yekuyedza inoshandiswa kugoko, chigaro chekumashure uye kuvharika kwemhepo, gasi inert, parafini, mvura kana isiri-corrosive fluid ine viscosity isingakwire kupfuura mvura.Iyo yakanyanya tembiricha yemvura yekuyedza i1250F.
Mhando dzebvunzo dzevhavha:
Shell bvunzo:
Backseat test
Inoitirwa mhando dzevharuvhu dzine chigaro chekumashure (pagedhi neglobe valve).Inoitwa nekuisa kumanikidza pavharuvhu yemuviri ine mamiriro evharuvhu akavhurika zvakazara, migumo yese yevharuvhu yekubatanidza yakavharwa uye gland barriers inotakura yakavhurika, kuve nechokwadi chekuti simba rinopesana nedhizaini yedhizaini uye kuona kuti hapana kudonha muvhavha yechisimbiso kana kuvhara gasket.
Pressure zvinodiwa:inoitwa nekudzvanywa kwe1.1 x kudzvanywa rating zvinhu pa1000F.
Low pressure yekuvhara bvunzo
Inoitwa nekutsikirira rumwe rutivi rwevhavha ine nzvimbo yevhavha yakavharwa, kusimbiswa kunoitwa nemhepo yemhepo uye rumwe rutivi rwekubatanidza rwakazaruka rwakatarisana uye rwakazadzwa nemvura, iyo inoputika ichaonekwa nekuda kwemhepo inoputika inobuda.
Pressure zvinodiwa:yakaitwa nedikidiki kudzvanywa kwe80 Psi.
High pressure closure test
Inoitwa nekutsikirira rumwe rutivi rwevhavha ine nzvimbo yevhavha yakavharwa, kumanikidzwa kunoitwa nemvura yemvura uye kudonha kuchaonekwa nekuda kwekubuda kwemadonhwe emvura.
Pressure zvinodiwa:inoitwa nekudzvanywa kwe1.1 x kudzvanywa rating zvinhu pa1000F
