(2) nzvimbo yekuisa chisimbiso haisi nyore kupfeka uye kukwenya, kuvharika kwakanaka, kuvhurika uye kuvhara pakati pevharuvhu disc uye yevhavha yemuviri yekuisa chisimbiso pamusoro pasina hama inotsvedza, saka kupfeka uye kukwenya hazvina kukomba, kuita chisimbiso kwakanaka, hupenyu hurefu hwebasa.
(3) pakuvhura nekuvhara, disc stroke idiki, saka kureba kwevhavha yeglobe idiki pane gedhi regedhi, asi kureba kwechimiro chakareba kupfuura gedhi revhavha.
(4) kuvhura nekuvhara torque yakakura, kuvhura nekuvhara kuvharika kwakaoma, kuvhura nekuvhara nguva ndiyo huru.
(5) kupikisa kwemvura kwakakura, nekuti chiteshi chepakati mukati memuviri wevharuvhu chine tortuous, kupikisa kwemvura kwakakura uye simba rekushandisa rakakura.
(6) apo zita rekumanikidza Pn munzira yekuyerera kwepakati iri pasi kana kuenzana ne16Mpa, inowanzodzika pasi, uye iyo yepakati inoyerera ichibva kune yakaderera nzira yevhavha disc;Nominal pressure Pn ≥ 20Mpa, kazhinji inoshandisa countercurrent, yepakati inoyerera kubva kune nzira ye disc.Kuwedzera simba rekuvhara.Kana iri kushandiswa, iyo yakachekwa-vharuvhu yepakati inogona kungoyerera munzira imwe chete uye haigone kushandura mafambiro ekuyerera.
(7) kana yakazaruka zvizere, dhisiki rinowanzo nyura.
Iyo axis yehunde yevharuvhu yevharuvhu yeglobe inotenderera kune yekuvharisa pamusoro pechigaro chevharuvhu.Stem yakavhurika/yakavharika sitiroko ipfupi uye ine yakavimbika yekucheka-kubvisa chiito, ichiita iyi vharafu yakakodzera yepakati kucheka-kubvisa kana kudzora uye throttling kushandiswa.

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
