Kana iwe uchida kuziva kana kubatanidzwa kwepombi yemvura yesimbi isina tsvina kwakasimba, kuedza kwekumanikidza kwepombi yemvura ndiyo imwe yenzira dzinowanzoshandiswa.Iyo yekumanikidza bvunzo inowanzopedzwa nekambani yekuisa, muridzi uye mutungamiri weprojekiti.Kushanda sei?Iro idambudziko rinowanzoitika kuwana kuti pombi yakakuvadzwa.Ndeipi muedzo wekumanikidza wepombi yemvura yesimbi isina tsvina yekuvandudza imba?
1. Chii chinonzi mwero
1. Iyo hydrostatic pressure ye hydrostatic test inofanira kunge iri kushanda kwepombi, muedzo wekuedza haufaniri kunge wakaderera kupfuura 0.80mpa, kushanda kwepombi kunofanira kunge kuri pasi pe0.8MPa, uye hydrostatic pressure test pressure inofanira kuva 0.8MPa.Iyo mhepo yekumanikidza bvunzo haigone kutsiva iyo hydrostatic bvunzo.
2. Mushure mokunge pombi yakazadzwa nemvura, chengetedza majoini akazaruka asina kuzadzwa, uye kubvisa chero kuparara.
3. Kureba kwepipeline hydrostatic test haifaniri kudarika 1000 mamita.Kune chikamu chepombi chine zvishongedzo pakati, kureba kwechikamu chekuongorora kwehydrostatic hakufaniri kudarika 500 metres.Mapaipi emhando dzakasiyana muhurongwa anofanirwa kuongororwa zvakasiyana.
4. Kuguma kwechikamu chepini yepini yekuedza kunofanira kuongororwa zvakasimba uye nekuvimbika.Munguva yekuedzwa kwekumanikidza, zvivako zvinotsigira hazvifaniri kusunungurwa uye kuputsika, uye valve haifaniri kushandiswa sendiro yekuisa chisimbiso.
5. Michina yemagetsi ine metering device inofanira kuchinjwa panguva yekumanikidza, kururamisa hakusi pasi pe 1.5, muedzo wekuedza ndeye 1.9 ~ 1.5 nguva ye metering range, uye dhayamita ye dial haisi pasi pe150 mm.
2. Nzira yekuedza
1. Kureba kwepombi yemvura yesimbi isina tsvina yekushongedza imba inofanira kutengwa maererano nemamiriro ezvinhu chaiwo, uye kureba kwepamusoro hakufaniri kudarika 500 mamita.
2. Kuvhara flanges kunofanirwa kuiswa kumativi ose epombi.Mushure mepakati yakavharwa nesilicon ndiro uye yakasungirirwa nemabhoti, vharafu yebhora inofanirwa kupihwa, uye vharafu yebhora ndiyo inopinza mvura uye yekubuda kwemvura.
3. Isa chiyereso chekumanikidza pamvura inopinza.
4. Kana pasina dzvinyiriro, muchina wokutsikirira unofanira kushandiswa kupinza mvura mupombi, uye ngwariro inofanira kubhadharwa pakuzarura gomba rokupinza mukati mokupinza mvura.
5. Mushure mokunge pombi yakazadzwa nemvura, gomba remhepo rinofanira kuvharwa.
6. Zvishoma nezvishoma wedzera kudzvanywa kwepombi kusvikira muedzo wekuedza wagadzikana kwemaminitsi makumi matatu.Kana kudzvinyirirwa kunodonha, kumanikidzwa kunogona kuwedzerwa mumvura yejekiseni, asi muedzo wekuedza haugone kudarika.
7. Tarisa majoini uye zvikamu zvepombi kuti hachina kubuda.Kana hongu, rega kuedza kudzvanywa, tsvaga chikonzero chekudonha uye gadzirisa.Tevera kutevedzana 5 kuti uedze kudzvanywa zvakare.
8. Kusunungurwa kwekumanikidzwa kunofanira kusvika ku50% yehuwandu hwekuedzwa kwekuedza.
9. Kana kudzvinyirirwa kwakadzikama pa50% yehuwandu hwepamusoro, uye kudzvinyirira kunokwira, kunoratidza kuti hapana mhepo inoputika.
10. Kuonekwa kunofanira kuongororwa zvakare 90 inches, kana pasina kuputika, muedzo wekuedzwa unokodzera.
