Large dhayamita spiral simbi pombi mugadziri
a.Munguva yekugadzira, ndiro yesimbi inoremara zvakaenzana, iyo yakasara kushushikana idiki, uye pamusoro haina kukweshwa. Iyo yakagadziridzwa spiral simbi pombi ine hukuru hwekuchinjika muhukuru uye yakatarwa dhayamita uye ukobvu hwemadziro, kunyanya mukugadzirwa kweyepamusoro-giredhi gobvu madziro pombi, kunyanya diki uye yepakati nepakati gobvu madziro pombi, ine zvakanakira zvisingaenzaniswi pane mamwe maitiro, uye inogona kusangana nezvimwe zvinodikanwa zvevashandisi mukutsanangurwa kwespiral simbi pombi.
b. Iyo yepamusoro mbiri-mativi yakanyura arc welding process inogona kuona welding panzvimbo yakanakisa, izvo zvisiri nyore kuve nekuremara senge kusarongeka, welding kutsauka uye kusakwana kwekupinda, uye zviri nyore kudzora kunaka kwewelding.
c. 100% kuongororwa kwehutano kunoitwa papombi yesimbi, kuitira kuti nzira yose yekugadzirwa kwepombi yesimbi iri pasi pekuonekwa uye kuongororwa kunobudirira, uye unhu hwechigadzirwa hunosimbiswa.
d. Yese midziyo yemutsetse wese wekugadzira ine basa rekubatanidza nekombuta yekutora data system kuona chaiyo-nguva yekufambisa data, uye tekinoroji paramita mukuita kwekugadzira inotariswa nepakati control room.
Iyo spiral simbi pombi ichave iri pasi pekuyedzwa kwemuchina, bvunzo yekubata kumeso uye flaring bvunzo isati yabuda mufekitori, uye inosangana nezvinodiwa zvakatsanangurwa muyero. Iyo yemhando yekuongorora nzira yeyakatwasuka seam simbi pombi ndeiyi inotevera:
1.Kutonga kubva pamusoro, ndiko kuti, mukutarisisa chitarisiko. Kuonekwa kwekutarisa kwemajoini akasungwa inzira yakapusa uye yakashandiswa zvakanyanya yekuongorora. Izvo zvakakosha zvemukati zvekupedzwa kwechigadzirwa chekuongorora. Izvo zvinonyanya kutsvaga kukanganisa pane weld surface uye dimensional kutsauka. Kazhinji, kuongorora kunoitwa kuburikidza nekutarisa kwekuona nerubatsiro rweyakajairwa template, geji, girazi rinokudza uye mamwe maturusi. Kana pane kukanganisa pane weld surface, panogona kunge paine kukanganisa mukati me weld.
2.Muedzo wenzira yemuviri: nzira yekuyedza yemuviri inzira yekuyera kana yekuyedza nekushandisa zvimwe zvinoitika zvemuviri. Nondestructive bvunzo inowanzo shandiswa kuongorora kukanganisa kwemukati kwezvinhu kana maworkpiece. NDT inosanganisira ultrasonic chikanganiso chekuonekwa, radiographic chikanganiso chekuonekwa, penetrant chikanganiso chekuonekwa, magineti kutadza kuona, nezvimwe.
3.Muedzo wesimba wemidziyo yekumanikidza: kuwedzera kune yakaomesesa bvunzo, bvunzo yesimba ichaitwa zvakare kune yekumanikidza midziyo. Kune marudzi maviri akajairika: hydrostatic bvunzo uye pneumatic bvunzo. Ivo vanogona kuyedza kusimba kwe weld yemidziyo nemapombi anoshanda pasi pekumanikidzwa. Pneumatic bvunzo inonyanya kunzwa uye nekukurumidza kupfuura hydraulic test. Panguva imwecheteyo, zvigadzirwa zvakaedzwa hazvidi kurapwa kwemvura, iyo inonyanya kukodzera kune zvigadzirwa zvine mvura yakaoma. Asi bvunzo ine ngozi kupfuura hydrostatic test. Munguva yekuyedzwa, inowirirana yekuchengetedza tekinoroji matanho anofanirwa kucherechedzwa kudzivirira tsaona panguva yekuyedzwa.
4.Compactness test: yemidziyo yakasungirirwa inochengeta mvura kana gasi, iyo isiri compactness kuremara kwewelds, senge inopinda mukati mepakatsemuka, pores, slag kuisirwa, isina kukwana kupinda uye yakasununguka chimiro, inogona kuwanikwa ne compactness bvunzo. Iyo compactness bvunzo nzira dzinosanganisira parafini bvunzo, mvura inotakura bvunzo, mvura kukanganisa bvunzo, nezvimwe.
5.Kune hydrostatic bvunzo, imwe neimwe pombi yesimbi ichave iri pasi peiyo hydrostatic bvunzo pasina kuvuza. Iyo yekumanikidza yekuyedza ichaverengerwa seP = 2st / D, uko s - Test Stress MPa ye hydrostatic bvunzo, uye bvunzo kushushikana kweiyo hydrostatic bvunzo ichasarudzwa se 60% yehushoma goho ukoshi hunotsanangurwa mune inoenderana simbi bhandi standard (Q235). iri 235m. Pressure stabilization time: D. the spiral weld of steel pipe for fluid transmission will be subject to X-ray or ultrasonic inspection (20%).
Zvinoenderana nemhando yekuongorora mhedzisiro yespiral simbi pombi, spiral simbi pombi inowanzo kupatsanurwa muzvikamu zvitatu: zvigadzirwa zvinogoneka, zvakagadziridzwa zvigadzirwa uye tsvina. Zvigadzirwa zvinokodzera zvinoreva spiral simbi mapaipi ayo kutaridzika kwemhando uye yemukati mhando inosangana neakakodzera zviyero kana tekinoroji mamiriro ekugamuchirwa kwekutumira; Zvigadzirwa zvakagadziridzwa zvinoreva spiral simbi mapaipi ayo maitiro ekuonekwa uye emukati emhando haazadzise zvakakwana zviyero uye kugamuchirwa kwemamiriro, asi anotenderwa kugadziriswa, uye anogona kusangana nezviyero uye kugamuchirwa mamiriro mushure mekugadzirisa; Zvimedu zvinoreva spiral simbi pombi iyo chitarisiko chemhando uye mhando yemukati haina kukodzera, iyo isingabvumidzwe kugadziriswa kana ichiri kutadza kuzadzisa zviyero uye mamiriro ekugamuchirwa mushure mekugadzirisa.
Zvigadzirwa zvemarara zvakakamurwa kuita tsvina yemukati uye marara ekunze. Tsvina yemukati inoreva marara spiral simbi pombi inowanikwa mu foundry kana foundry workshop; Tsvina yekunze inoreva marara anowanikwa mushure mekuburitswa kwespiral simbi pombi, iyo inowanzofumurwa mukugadzirisa machining, kupisa kupisa kana kushandiswa, uye kurasikirwa kwayo kwehupfumi kwakakura kupfuura iyo yemukati tsvina. Kuti uderedze tsvina yekunze, pombi dzesimbi dzakatenderedzwa dzinogadzirwa mumabhechi dzinofanirwa kutorwa sampuli yekuyedza kupisa kupisa uye kugadzirwa kwakashata usati wabuda mufekitori, uye zvingangoita spiral simbi pombi hurema hunofanirwa kuwanikwa muspiral simbi pombi chirimwa kusvika pazvinobvira, saka. sekutora matanho anodiwa ekugadzirisa nekukurumidza.
1) Diki nepakati-saizi chikamu simbi, waya tsvimbo, kusimbisa, yepakati dhayamita simbi pombi, simbi waya uye simbi waya tambo zvinogona kuchengetwa mutsime inofefetera shedhi, asi vanofanira kuvharwa uye padded.
2) Imwe simbi diki, simbi pepa, simbi tambo, silicon simbi pepa, diki-dhayamita kana nhete-madziro simbi pombi, akasiyana-siyana anotonhora-akakungurutswa uye anotonhora anodhonzwa simbi uye zvigadzirwa zvesimbi zvine mutengo wakakwira uye corrosion zviri nyore zvinogona kuchengetwa mudura.
3)Nzvimbo kana imba yekuchengetera zvinhu zvepombi yesimbi inotenderera ichave iri munzvimbo yakachena uye isina kuvharika, kure nemafekitari nemigodhi inoburitsa gasi rinokuvadza kana huruva. Masora nemhando dzose dzichabviswa panzvimbo kuitira kuchengetedza simbi yakachena.
4) Yakakura chikamu simbi, njanji, simbi ndiro, hombe-diameter simbi pombi, forging, etc. anogona akaturikidzana mumhepo yakashama.
5)Izvo hazvibvumidzwe kurongedza neasidhi, alkali, munyu, simende uye zvimwe zvinhu zvinosvibisa simbi mudura. Mhando dzakasiyana dzesimbi dzinofanira kuiswa zvakaparadzana kudzivirira kuvhiringika uye kubata ngura.
6)Imba yekuchengetera zvinhu ichasarudzwa zvinoenderana nemamiriro enzvimbo. Kazhinji, inotora yakajairwa yakavharwa imba yekuchengetera, kureva, imba yekuchengetera ine denga, yakavharirwa, magonhi akasimba nemahwindo uye nemidziyo yekufemesa.
7) Imba yekuchengetera zvinhu ichapinzwa mhepo mumazuva ezuva, yakavharwa mumazuva ekunaya kudzivirira unyoro, uye nguva dzose kuchengetedza nzvimbo yakakodzera yekuchengetedza.
