1.Mamiriro uye Kugadzirira Kuedza Kudzvinyirira
1.1 Kuvakwa kwepombi system kunopedzwa, uye inosangana nezvinodiwa zvekugadzira uye zvakatemwa.
1.2 Basa rekushongedza rinopedzwa mushure mekusanganisa rack uye rack yepombi yakaiswa.Iyo ray yekuona yasvika zvizere kune dhizaini yakatarwa uye yakapfuura kuongororwa.Iwo welds nedzimwe nzvimbo dzekutarisa dzinofanirwa kuedzwa hadzina kupendwa uye insulated.
1.3 Muyedzo wekudzvanya geji yakasimbiswa, uye iko kurongeka ndeye 1.5 mazinga.Iyo yakazara-chiyero kukosha kwetafura inofanira kuva 1.5 kusvika 2 nguva yakayerwa kusvika pakumanikidzwa kukuru.
1.4 Muyedzo usati waitwa, haugone kutora chikamu muyedzo system, midziyo uye zvishongedzo, uye wowedzera pendi chena ine label yependi chena ine ndiro yebofu.
1.5Mvura inofanira kushandiswa pakuchenesa mvura, uye zviri mukati me chloride mumvura hazvifaniri kudarika 25 × 10-6 (25ppm).
1.6 Kwekanguva pombi yekusimbisa yebvunzo inofanirwa kusimbiswa uye yakavimbika mushure mekuongororwa.
1.7 Tarisa uone kana mavharuvhu ese ari papombi akavhurika, kana mapedhi awedzerwa, womisa core yevharuvhu yepakati pevharuvhu, wozoisa patsva kusvika yafuridzirwa.
2.Process Pipeline Test Pressure Process
2.1.Pipeline test pressure ndiyo 1.5 times the design pressure.
2.2.Kana pombi nemidziyo zvichiyedzwa sehurongwa, kuyedza kumanikidza kwepombi kwakaenzana kana kushoma pane kudzvanywa kwechishandiso.Essence
2.3.Kana jekiseni remvura regadziriro, mhepo inofanira kupera.Nzvimbo yekubudisa mhepo inofanira kunge iri panzvimbo yakakwirira yepombi uye kuwedzera vheji yekupedza.
2.4.Mapaipi ane zvinzvimbo zvakakura anofanirwa kuyerwa mukati mekudzvanywa kweye test medium.Kudzvanywa kweyedzo yepombi yemvura kunofanirwa kuve pasi pekumanikidzwa kwepamusoro-soro, asi nzvimbo yakaderera yenzvimbo shoma haifanire kudarika kushivirira kwekuumbwa kwepombi.
2.5.Kana bvunzo kudzvanywa, kukwidziridzwa kunofanira kuitwa zvishoma nezvishoma.Mushure mekumanikidzwa kwekuyedza kwasvika, kudzvanywa kunofanirwa kunge kuri maminetsi gumi.Pasina kuvuza, hapana deformation inokodzera, uye ipapo kudzvanywa kwebvunzo kunoderedzwa kune dhizaini yekugadzira.Essence
2.6.Mushure mekuedzwa kwapera, ndiro yebofu inofanira kubviswa munguva yekupedza mvura.Munguva yemvura, kudzvinyirirwa kwakashata kunofanira kudzivirirwa, uye hapana mvura inogona kudonhedzwa chero kupi zvako.Kana kuputika kunowanikwa panguva yekuedzwa, hazvibvumirwi kurapwa nekumanikidzwa.Mushure mokubvisa kukanganisa, muedzo unofanirwa kuongororwa zvakare.
2.7.Iyo leakage bvunzo yakaitwa mushure mekudzvanywa bvunzo, uye svikiro rekuyedza rakamanikidzwa nemhepo yakamanikidzwa.
2.8.Dzvinyiriro yebvunzo yekudonha ndiyo dhizaini yekugadzira.Iyo leakage bvunzo inofanirwa kutarisa kutarisa tsamba yekuzadza.Iyo flange kana shinda yakabatana nevharuvhu isina chinhu, exhaust valve, uye drainage valve.
3. Craft pombi inofuridza nekuchenesa
3.1.Technology zvinodiwa
3.1.1 Mutoo wepombi unofanirwa kufuridzirwa uye kucheneswa muzvikamu (zvinonzi kuvhuvhuta).
3.1.2 Nzira yekufuridza inotarwa maererano nezvinodiwa zvepombi, svikiro rekushanda, uye tsvina iri pamusoro pepombi.Kutevedzana kwekuvhuvhuta kunowanzoitwa kurongeka mukurongeka kwemutariri, tsigiro, uye pombi dzekuburitsa.
3.1.3 Usati waridza, chiridzwa chiri muhurongwa chinofanira kuchengetedzwa, uye pore board, filter regulating valve uye stoping valve core inofanira kuparadzwa, uye inochengetwa zvakanaka.
3.1.4 Panguva yekurova, madhaidhi haafaniri kupinda mumudziyo, uye nhengo dzinoputirwa kunze kwemudziyo hadzifaniri kupinda mupombi.
3.1.5 Midziyo nemapombi asingabvumidzwe kuwachwa anofanirwa kunge ari ega kubva pakufuridza.
3.1.6 Kufuridza kwepombi kunofanira kuva nekuyerera kwakakwana.Dzvinyiriro yekuvhuvhuta haifanire kudarika dhizaini yekugadzira.Mwero wekuyerera kazhinji hausi pasi pe20m/s.Pakuridza, shandisa sando yemapuranga kugogodza chubhu.Usakuvadza chubhu.
3.1.7 Funga kusimba kwebazi repombi uye rack yekurembera isati yafuridza, uye kusimbisa kunofanira kupihwa kana zvichidikanwa.
3.2.Kuputika kwepombi, nzira yekuchenesa
3.2.1 Kugezeswa kwemvura: Nzvimbo yekushanda ipombi yegadziriro yemvura.Mvura inosuka inogona kusvika pakuyerera kwepamusoro kana kusingasviki 1.5m/s mupombi.Ruvara rwemvura kunze kwenyika uye kujeka kunopindirana nekutarisa kwekuona pamusuwo.Mushure mokunge pombi inokodzera, mvura inofanira kupera nenguva.
3.2.2 Kuvhuvhuta kwemhepo: Chimiro chekushanda ipombi yegesi.Chero ani anosangana nevharuvhu anofanira kupatsanura flange yapfuura uye owedzera baffle, uye wozogadzirisa mushure mekunge pombi yafuridzirwa.Kumanikidzwa hakufaniri kudarika dhizaini yekugadzira yemudziyo uye pombi, uye chiyero chekuyerera hachifaniri kunge chiri pasi pe20m / s.Munguva yekuvhuvhuta kwemhepo, kana ichionekwa ichipedza utsi neguruva, iyo yemapuranga inonangwa bhodhi yekuongorora yependi chena inoiswa pachiteshi chekuburitsa, uye hapana ngura, guruva, mwando uye mamwe madhiri pabhodhi rakanangwa remaminitsi mashanu.
3.2.3 Kuvhuvhuta kweutsi: Nzvimbo yekushanda inoongororwa nemapombi ehutsi.Chipfunga chisati chavhuvhuta, chubhu inodziya inofanira kusimudzwa zvishoma nezvishoma kuti ifuridzwe, uye yobva yatonhorera kusvika kune tembiricha yezvakatipoteredza.Muromo wenzvimbo yekubuditsa yemhepo yakarerekera kumusoro, uye logo inobata ziso.Iyo dhayamita yepombi yekupedza haifaniri kuva duku kudarika dhayamita yepombi inoputika.Maitiro ekufanirwa: tsiva bhodhi rakanangwa kaviri mumutsara.Pasi pemamiriro ezvinhu ezvese zvikwaniriso), ndeye scanning qualification.
3.2.4 Kugadziriswa kwepombi: Mushure mokunge kuedzwa kwepombi uye kuvhuvhuta kwakakodzera, bhodhi rebofu rinofanira kubviswa panguva yakakodzera maererano nezvinyorwa, uye girafu inogadzirisa inogadzirisa, inomisa nheyo yevhavha, chinhu chiridzwa.
