Lub hydraulic pipelinentaus ntawv yog thawj qhov project ntawm hydraulic khoom installation.Qhov zoo ntawm cov khoom siv kav dej yog ib qho ntawm cov yuam sij rau kev ua haujlwm ib txwm ua haujlwm ntawm hydraulic system.
1. Thaum npaj thiab xa cov kav dej, yuav tsum muaj kev txiav txim siab dav dav rau cov khoom siv, cov khoom siv hydraulic, cov yeeb nkab txuas, thiab cov flanges uas yuav tsum tau txuas nrog raws li daim duab hydraulic schematic.
2. Kev tso, kev teeb tsa, thiab kev taw qhia ntawm cov kav dej yuav tsum ua kom zoo thiab sib xws, nrog cov txheej txheem meej.Sim xaiv cov kab rov tav lossis cov yeeb nkab ncaj, thiab qhov tsis sib xws ntawm cov kav dej kab rov tav yuav tsum yog ≤ 2/1000;Qhov tsis ncaj ntawm txoj kab ncaj nraim yuav tsum yog ≤ 2/400.Kos nrog ib theem ntsuas.
3. Yuav tsum muaj qhov sib txawv ntawm ntau tshaj 10mm ntawm cov kab sib txuas lossis cov kav dej sib txuas.
4. Cov khoom siv ntawm cov kav dej yog tsim nyog los pab txhawb kev thauj khoom, tshem tawm, thiab kho cov kav dej, hydraulic li qub, thiab lwm yam khoom siv.Txhua ntu ntawm cov kav dej lossis cov khoom siv hauv lub cev yuav tsum tuaj yeem muab tshem tawm thiab sib sau ua ke dawb li ntau li ntau tau yam tsis muaj kev cuam tshuam rau lwm yam khoom.
5. Thaum piping hydraulic system, nws yog ib qho tsim nyog los xyuas kom meej tias cov kav dej muaj qee qhov kev nruj thiab muaj peev xwm tiv thaiv oscillation.Cov yeeb nkab txhawb nqa thiab clamps yuav tsum tau tsim kom tsim nyog.Twisted kav yuav tsum tau nruab nrog brackets los yog clamps nyob ze ntawm lub bending point.Lub raj xa dej yuav tsum tsis txhob txuas ncaj qha mus rau lub bracket lossis yeeb nkab clamp.
6. Cov khoom siv ntawm cov kav dej yuav tsum tsis txhob raug lees txais los ntawm cov li qub, cov twj tso kua mis, thiab lwm yam hydraulic Cheebtsam thiab accessories;Cov khoom siv hnyav hnyav yuav tsum tsis txhob txhawb nqa los ntawm cov kav dej.
7. Nws yog ib qho tsim nyog yuav tau xav txog cov txheej txheem tseem ceeb rau cov kav dej ntev dua los tiv thaiv kev ntxhov siab los ntawm kev hloov kub uas ua rau cov yeeb nkab nthuav dav thiab kev cog lus.
8. Nws yog ib qho tsim nyog yuav tsum muaj lub hauv paus meej meej rau cov khoom siv raw khoom siv hauv cov kav dej, thiab cov kav dej uas tsis paub txog cov khoom siv raw tsis raug tso cai siv.
9. Hydraulic system piping nrog lub cheeb ntawm tsawg dua 50mm tuaj yeem txiav nrog lub log sib tsoo.Cov kav dej uas muaj txoj kab uas hla ntawm 50mm lossis ntau dua yuav tsum tau txiav los ntawm kev siv tshuab.Yog tias siv cov roj txiav, nws yog ib qho tsim nyog yuav tsum siv cov txheej txheem kev ua haujlwm kom tshem tawm cov khoom uas tau hloov pauv vim qhov kev npaj ntawm cov roj txiav, thiab tib lub sijhawm, qhov vuam zawj tuaj yeem tig tawm.Tsuas yog cov roj kav xa rov qab, nws tsis raug tso cai siv lub tshuab rau cov menyuam kneading cutter los txiav lub siab ntawm cov kav dej.Nws yog ib qho tsim nyog yuav tsum tau txiav qhov saum npoo ntawm cov yeeb nkab tiaj tus thiab tshem tawm cov burrs, oxide ntawm daim tawv nqaij, slag, thiab lwm yam. Qhov chaw txiav yuav tsum ncaj nrog lub axis ntawm cov yeeb nkab.
10. Thaum lub raj xa dej yog tsim los ntawm ntau cov yeeb nkab thiab cov khoom siv txhawb nqa, nws yuav tsum tau txais ib qho los ntawm ib qho, ua tiav ib ntu, sib sau ua ke, thiab tom qab ntawd nruab nrog cov seem txuas ntxiv kom tsis txhob muaj qhov yuam kev tom qab ib qho vuam.
11. Yuav kom txo qis ib feem ntawm kev poob siab, txhua ntu ntawm cov kav dej yuav tsum tiv thaiv kev nthuav dav sai lossis txo qis ntawm ntu ntu thiab ntse twists.
12. Cov yeeb nkab txuas nrog cov yeeb nkab sib txuas lossis flange yuav tsum yog ntu ncaj nraim, uas yog, axis ntawm ntu ntawm cov yeeb nkab yuav tsum sib npaug thiab sib npaug nrog cov axis ntawm cov yeeb nkab sib txuas lossis flange.Qhov ntev ntawm txoj kab ncaj nraim no yuav tsum siab dua lossis sib npaug li 2 npaug ntawm txoj kab uas hla.
13. Txoj kev khoov txias tuaj yeem siv tau rau cov kav dej uas muaj txoj kab uas hla sab nraud tsawg dua 30mm.Thaum txoj kab uas hla ntawm cov yeeb nkab yog nruab nrab ntawm 30-50mm, txoj kev khoov txias lossis kub dabtsi yog khoov tuaj yeem siv.Thaum txoj kab uas hla ntawm cov yeeb nkab yog ntau dua 50mm, feem ntau yog siv txoj kev kub bending.
14. Welders uas weld hydraulic pipelines yuav tsum tuav ib tug siv tau high-pressure pipeline vuam daim ntawv pov thawj tsim nyog.
15. Kev xaiv ntawm vuam tshuab: Acetylene gas welding feem ntau yog siv rau cov kav dej nrog phab ntsa tuab ntawm feem ntau 2 hli los yog tsawg dua hauv cov kav dej carbon steel.Arc vuam yog tsuas yog siv rau cov kav dej nrog carbon steel yeeb nkab phab ntsa thickness ntau dua 2 hli.Nws yog qhov zoo tshaj plaws los siv argon arc vuam rau vuam ntawm cov kav dej.Rau cov kav dej uas muaj phab ntsa thickness ntau dua 5 hli, argon arc vuam yuav tsum tau siv rau priming thiab Arc vuam yuav tsum tau siv rau sau.Thaum tsim nyog, vuam yuav tsum tau nqa tawm los ntawm kev sau cov yeeb nkab qhov nrog kev tu roj.
16. Weld rods thiab fluxes yuav tsum tau sib phim nrog cov khoom siv welded yeeb nkab, thiab lawv cov cim kev lag luam yuav tsum ua kom pom tseeb raws li cov khoom siv, muaj daim ntawv pov thawj khoom tsim nyog, thiab nyob rau hauv lub sijhawm siv tau zoo.Vuam rods thiab fluxes yuav tsum tau qhuav raws li cov kev cai ntawm lawv cov khoom siv phau ntawv ua ntej siv, thiab lawv yuav tsum tau khaws cia qhuav thaum siv thiab siv nyob rau tib hnub.Lub electrode txheej yuav tsum tsis txhob poob thiab pom tseeb tawg.
17. Lub taub qab vuam yuav tsum tau siv rau hydraulic pipeline vuam.Ua ntej vuam, av, roj stains, noo noo, thiab xeb me ntsis ntawm qhov chaw ntawm qhov zawj thiab nws qhov chaw nyob ib sab nrog qhov dav ntawm 10-20mm yuav tsum tau muab tshem tawm thiab ntxuav.
18. Lub taub qab vuam flanges yuav tsum tau siv rau vuam ntawm cov kav dej thiab flanges, thiab tho flanges yuav tsum tsis txhob siv.
19. Lub taub qab vuam yuav tsum tau siv rau kev sib txuas ntawm cov kav dej thiab cov yeeb nkab sib txuas, thiab kev nkag mus vuam yuav tsum tsis txhob siv.
20. Lub taub qab vuam yuav tsum tau siv rau kev sib txuas ntawm cov kav dej, thiab kev nkag mus vuam tsis raug tso cai.
