Kuburikidza nekuongorora musimboti wechimiro chevharuvhu yebhora yepombi yakagadziriswa, kwakawanikwa kuti musimboti wekuvhara wakafanana, uchishandisa musimboti we "piston effect", uye chimiro chekuvhara chete ndicho chakasiyana.
Valve mukushandiswa kwedambudziko iri inonyanya kuratidzwa mumazinga akasiyana, maitiro akasiyana ekubuda kwemvura, zvichienderana nepfungwa yekuvhara chimiro uye kuisirwa uye kuongorora kwemhando yekuvaka, zvikonzero zvekubuda kwevharuvhu ndizvo zvinotevera.
1. Kuiswa kwevharuvhu uye hunhu hwekuvaka ndicho chikonzero chikuru
Mukugadzirwa kwekuisa, hapana hanya nekudzivirira kwevharuvhu pamusoro pechisimbiso uye rin'i yechigaro, kukuvara kwechisimbiso; kuiswa kwapera, kuvhuvhuta kwepombi nevharuvhu hakusati kwapera, hakuna kuchena, pakushanda pane slag kana gravel zvakanamirwa pakati pebhora nerin'i yechigaro, zvichikonzera kutadza kwechisimbiso. Muchiitiko ichi, kana paine emergency, nzvimbo yekuvharira yepamusoro inofanira kuiswa chisimbiso kwenguva pfupi kuti ideredze kubuda kwemvura, asi haigone kugadzirisa dambudziko racho zvizere, kana zvichidikanwa, nzvimbo yekuvharira yevharuvhu nerin'i yechigaro inofanira kutsiviwa.
2. Kugadziriswa kwevharuvhu, zvinhu zvemhete yekuvhara, uye zvikonzero zvemhando yegungano
Kunyangwe chimiro chevharuvhu chiri nyore, chinodiwa zvakanyanya kune zvigadzirwa zvemhando yepamusoro zvekugadzirisa michina, hunhu hwayo hwekugadzirisa hunokanganisa zvakananga mashandiro ekuvhara. Mhete yechigaro chekuvhara uye nzvimbo yechigaro chemhete yekuvhara uye nzvimbo yega yega yemhete inofanira kuverengerwa nemazvo, kuomarara kwenzvimbo yacho kuve kwakakodzera. Pamusoro pezvo, kusarudzwa kwezvinhu zvakapfava zvekuvhara kwakakoshawo, kwete kungofunga nezvengura uye kuramba kupfeka asiwo kufunga nezvekusimba kwayo. Kana yakapfava zvakanyanya, inokanganisa kugona kwayo kuzvichenesa; kana yakaoma zvakanyanya, ichave nyore kutyoka.
3. Kusarudzwa kwakanaka zvichienderana nekunyorera uye mamiriro ekushanda
Maitiro akasiyana ekuvharira uye maumbirwo ekuvharira evharuvhu achishandisa zviitiko zvakasiyana, zviitiko zvakasiyana chete kusarudza vharuvhu yakasiyana, kuti uwane mhedzisiro yakakodzera yekushandisa. Semuenzaniso, kana iri pombi yegesi yeWest-East, mavharuvhu ebhora epombi akasimbiswa ane bi-directional sealing anofanira kusarudzwa zvakanyanya sezvinobvira (kunze kwemavharuvhu ebhora eorbital ane forced sealing, ayo anodhura zvakanyanya). Nenzira iyi, kana upstream seal yakakuvara, downstream seal inogona kuramba ichishanda. Forcedly sealed track ball valve inofanira kusarudzwa kana kuvimbika kwakazara kuchidikanwa.
4. Kune mavharuvhu ane magadzirirwo akasiyana ekuvharira, nzira dzakasiyana dzekushanda, kugadzirisa, uye kugadzirisa dzinofanira kushandiswa
Kune mavharuvhu asina maburi, vharuvhu inogona kuzadzwa nemafuta usati watanga uye mushure mekushanda kwega kwega kana mwedzi mitanhatu yega yega muzvikamu zvidiki panzvimbo dzinopinzwa maburi ne sealant, uye chete kana maburi akabuda kana kuti asingakwanise kuvharwa zvachose ndipo panopinzwa huwandu hwakakodzera hwe sealant. Nekuda kwekusimba kwakanyanya kwe sealant, kana vharuvhu isingawanzo zadzwa ne sealant, inokanganisa mhedzisiro yekuzvichenesa kwenzvimbo yakatenderera, kazhinji isingabatsire, ichiunza grit diki nedzimwe tsvina pakati pe seal kuti iite kuti pave nekubuda. Kune mavharuvhu ane seal ine nzira mbiri, kana mamiriro ekuchengetedza panzvimbo akabvumidza, kumanikidzwa muvharuvhu kunofanira kusunungurwa kusvika zero, kuve nechokwadi chekuvharwa.
