- Mamiriro uye kugadzirira kwehunyanzvi pombi yekuyedza kumanikidza
I.1.Iyo pombi system inopedzwa uye inoenderana nezvinodiwa zvekugadzira uye mirau.
I.2.Bazi, hanger uye pombi rack zvakapedzwa, uye ray flaw yekuona yasvika zvachose kune zvakatemwa zvekugadzira, uye chikamu chebvunzo, weld nezvimwe zvinofanirwa kuongororwa hazvina kupendwa uye incubated.
I.3.Chiyero chekumanikidza gauge chakasimbiswa, iko kurongeka kwakaiswa ku1.5, uye iyo yakazara chiyero kukosha kwetafura kunofanirwa kuve 1.5 kusvika 2 nguva iyo yakanyanya kudzvanywa kuyerwa.
I.4.Pamberi pekuyedzwa, iyo yekuedza system, zvishandiso uye zvakabatanidzwa hazvizobatanidzwe muyedzo system, uye chinzvimbo chebhodhi bofu chinoshandiswa kushandisa chena lacquer lacquered chiratidzo uye rekodhi.
I.5.Mvura yekuedza inofanira kushandiswa nemvura yakachena, uye chloride ion iri mumvura haifaniri kudarika 25 × 10-6 (25 ppm).
I.6.Iyo pombi yenguva pfupi yekuedzwa inosimbiswa, uye kuchengetedzeka uye kuvimbika kunofanirwa kuongororwa.
I.7.Tarisa kana mavharuvhu ese ari papombi ari panzvimbo yakashama, kana ma spacers akawedzerwa, uye iyo retracting valve core inofanira kubviswa, uye mushure mekucheneswa kunogona kugadziridzwa.
2. Process pipeline test
2.1.Pipe test pressure ndiyo 1.5 times the design pressure.
2.2. Kana pombi nemidziyo zvichiyedzwa sehurongwa, kudzvanywa kwepombi kwakaenzana kana kuderera pane kudzvanywa kwechigadzirwa, uye kudzvanywa kwechigadzirwa hakusi pasi pe1.15 nguva yepombi dhizaini yekumanikidza, uye inogona kuedzwa maererano nekudzvanywa kwekuedzwa kwemidziyo.
2.3.When iyo system inobayiwa, mhepo inofanirwa kupera, nzvimbo yekuburitsa mhepo inofanirwa kunge iri iyo yepamusoro pombi yepombi, uye kuwedzera vharafu yekupedza.
2.4. Pamapaipi ane misiyano yakakura, iyo static pressure yemuyedzo wepakati inofanira kuyerwa mukudzvanywa kwebvunzo.Kudzvanywa kweyedzo yepombi yemvura kunofanirwa kuve pasi pekumanikidzwa kwepamusoro-soro, asi iyo yakaderera point pressure haifanire kudarika zvikamu zvechubhu.
2.5. Kana dzvinyiriro ichidzvinyirirwa, kukwidziridzwa kunofanirwa kunonoka, uye mushure mekudzvanywa kwekuyedza kwasvika, inodzorwa kwemaminetsi gumi, uye hapana deformation isina kubuda.Iyo yekumanikidza yekuyedza inodonha kune dhizaini yedhizaini, inomira maminetsi makumi matatu, uye kudzvanywa hakudonha, hapana kuvuza kunokodzera.
2.6. Mushure mokuedzwa, ndiro yebofu inofanira kubviswa munguva, uye mvura inoiswa, uye kudzvinyirira kwakashata kunofanira kudzivirirwa kana kudonhedzwa, uye haifaniri kubvisa mvura.Apo kuputika kunowanikwa panguva yekuedzwa, haifaniri kugadziriswa, mushure mokubvisa kukanganisa, inofanira kuongororwa zvakare.
2.7.Iyo leakage bvunzo yakaitwa mushure mekudzvanywa bvunzo, uye svikiro rekuyedza rakashandiswa mhepo yakamanikidzwa.
2.8. Leakage test pressure yakagadzirirwa kugadzira pressure, leak test inofanira kutarisa pakutarisa filler, flange kana threaded joints, vent valve, exhaust valve, drainage valve, etc., ine furo agent inspection pasina kubuda.
3. craft pombi kuchenesa uye kuchenesa
3.1. Process tekinoroji zvinodiwa
3.1.1. Pombi yekugadzira inofanira kupatsanurwa uye kuchenesa (inonzi kuchenesa).
3.1.2. Iyo nzira yekufuridza inotarwa zvinoenderana nezvinodiwa zvekushandiswa kwepombi, iyo yakasviba maitiro epamusoro pepakati pekushanda uye pombi yemukati inotarwa, uye kuomeswa kwebvudzi kunowanzoitwa maererano nemutariri, pombi yebazi. , uye kubuda kwechubhu.
3.1.3. Usati waridza, chiridzwa chiri mukati megadziriro chinofanira kuchengetedzwa uye kubvisa orifice plate, valve yekugadzirisa sefa uye muviri wevhavha yakadzoserwa, nezvimwewo, zvakanaka, nezvimwe zvakadaro.
3.1.4. Paunenge uchichenesa, tsvina mupombi haifaniri kupinda mumidziyo, uye tsvina inoputika kubva pachigadziro haifaniri kupinda pombi, flange yevhavha inowedzerwa.
3.1.5. Kucheneswa kwepombi kunofanirwa kuve nekuyerera kwakakwana, uye kudzvanywa kwekuchenesa hakufanire kudarika dhizaini yekugadzira, uye chiyero chekuyerera kazhinji hachisviki makumi maviri m / s.Paunenge uchichenesa, shandisa nyundo yehuni kuti urove chubhu, uye tarisa pane weld uye pasi pepombi, asi haufaniri kukuvadza pombi.
3.1.6. Davi repombi rinofanira kutariswa risati ravhuvhuta, uye rigging ye hanger inofanira kusimbiswa kana zvichidikanwa.
3.2. Kucheneswa kwepombi, nzira yekuchenesa
3.2.1. Mvura yekugezesa: Kushanda svikiro ndiyo pombi yemvura system.Mvura yekugezesa inogona kusvika kune yakanyanya kuyerera mwero kana isingasviki 1.5 m / s muchubhu.Iyo inokodzera kune kunze kwenyika mvura uye pachena nemusuwo.Mushure mokunge pombi yakashambidzwa, mvura inofanira kupera munguva.
3.2.2.Kucheneswa kwemhepo: Kushanda svikiro kunocheneswa zvishoma nezvishoma neakamanikidzwa mweya zvikamu zvemapaipi egasi.Kana ukasangana nevhavha, unofanira kubvisa flange mberi kune bhodhi rekuvhara, uye wozogadzirisa zvakare mushure mokunge pombi yaputika.Kumanikidzwa hakufanire kudarika chigadziko uye pombi dhizaini yekumanikidza, uye kuyerera hakufanirwe kunge kuri pasi pe20 m / s.Munguva yekuchenesa mhepo, kana gasi rekupedza risiri kusvuta, chiteshi chemagetsi chinoiswa muchiteshi chemagetsi kuti chiedze chinangwa chehuni chine lacquered, uye hapana ngura, guruva, unyoro, uye mamwe marara pane inotangwa ndiro mu5 min.
3.2.3.Steam purge: Iyo yekushanda inocheneswa neutsi mupombi yeutsi.Utsi hunocheneswa chubhu inodziya isati yanonoka, yobva yatonhorera kusvika kumatembiricha ambient, wobva wasimudza chubhu inodziya, woita kechipiri kuchenesa, saka kudzokorora hakumbosviki katatu.Iyo gasi yekuburitsa mumhute yekuchenesa yakarerekera kumusoro, uye chiratidzo chinokwezva maziso.Iyo yekuburitsa pombi dhayamita haifanirwe kunge iri pasi peiyo dhayamita yechubhu yekuchenesa.Yakakodzera mwero: Kaviri kutsiva zvinangwa zvenguva mbiri dzakateedzana, senge makwapa anoonekwa neasina kupfeka pane yakanangwa plate saizi pazasi φ 0.6mm, kudzika kwekudzika 1 / cm2;nguva yekuchenesa maminetsi gumi nemashanu (kureva maviri Munyaya yekupfuura, inopfuudzwa.
