Rau lub tshuab nqus tsev jackinged piping system
Lub Tshuab Nqus Tsev BayKev sib txuaNtaus nrog flanges thiab bolts
Lub installation ceev faj
Lub VJP(lub tshuab nqus tsev jackinged piping)Yuav tsum muab tso rau hauv qhov chaw qhuav tsis muaj cua ua ntej kev teeb tsa.Tussab nraudntimtxheej Vjp tsis taube qhibed, Txhawm rau tiv thaiv lub raj rau hauv lub cev txawv teb chaws (xuab zeb, cov kab mob me, thiab lwm yam). Nyob rau hauv los nag los yog ntevntug dejHuab cua, kuj yuav tsum tau them nyiaj tshwj xeeb rau sab hauv ntawm cov raj xa dej.
Nws yog txwv tsis pub siv VJP ncaj qha mus rau Vuam Electrode, tawm tsam arclossis vuam ntawm VJP.
Lub VJPntimTxheej tsis tau muab tshem tawm kom txog thaum cov yeeb nkab raug ntsia kom tiv thaiv qhov kev sib tsoo hauv lwm txoj haujlwm.
Thaum lub sij hawm tag nrho cov txheej txheem teeb tsa, vjp yuav tsum ua tib zoo tuavCov. Tiv thaiv ob xausntawm vjp, tsis txhob siv lublub tshuab nqus tsevSib koom rau Vjp (Daim duab 1 thiab 3) raws li qhov taw tes rau kev tiv thaiv kom tiv thaiv tsis taus dej xau.
Thaum txhim kho, xyuam xim rau kev ntseeg tau ntawm hoisting, tsis txhob poob thiab kev puas tsuaj lossis raug mob.
Cov kauj ruam teeb tsa ntawm VJP
1. Kuajtuskev kos duabs, seb qhov ntau npaum li cas thiab qhov ntevntawm cov kav dejNtawm cov duab kos yog tib yamnrogtusluam ntawv pipesCov. Before install, nrhiavtawmTxhua Vjp raws li kev kos duab thiabtus nab npawjCov. Piv txwv li:HL2018Lub ntsiab-59-02-02-01, uas txhais tau tias qhov project code yog 59, ua kua nitrogen nruab nrab, yeeb nkabTsis yog.01 ntawm kabTsis yog.02. Ib qho hlau xa nrog qhov notus nab npawjtxuas nrog Vjp ntawm lub xaib (Daim duab 1), thiab ib qho hluav taws xob corrosion yog txuas nrogze ntawm lub tshuab nqus tsevtusVjp(Daim duab 2).
Nco tseg: tusqho ntauthiab tsis muaj.ntawm cov kav dej hauv daim duab yuav tsum yog tib yam li covqho ntauthiabTsis yog.ntawmVjpsrau ntawm qhov chaw. Yog tias muaj qhov tsis sib xws hauv kev kuaj, nco ntsoov hu rau peb cov neeg ua haujlwm ntawm lub xaib.
2. Tom qab kuaj xyuas VJP kom muaj nuj nqis thiabTsis yog.,Raws li cov duab kos, tsivLub VJPsntawm kev sib ntaus sib tws / txhawb nqalossis qhov chawVjpsnyob rau hauv av ib sab ntawm cov kev sib tws / txhawb nqa.
3. Ua ntej cov flanges txuas nrog, ua ntej tshuaj xyuas seb cov foob pob tw thiab cov tshuab txias ntim tau nruab
4. Ntxuav cov pob qij txha ntawmPoj Niam & Txiv Neejtsev txuas ntxivtus kav dej, FOOBib ncigThiab txias lub tsev teev nrog roj-dawb thiab dej-dawb reagent.
5. Ntxig tus txiv neej thiab poj niam txuas ntxiv cov yas kab rov tav thiab maj mam. Tom qab ntawd rub ob lub pluaj ob zaug ua ke thiab nias, thiab nruab txhua qhov bolts ntawm cov flanges (tsis txhob zawm lawv tam sim no).
6. Tom qab ua kom tiav qhov tseeb ntawm ob lub pluaj, zawm cov bolts ib kauj ruam los ntawm kauj ruam. Xyuas kom meej tias cov flange yog cia qib thaum lub sijhawm teeb tsa
7. Tshawb xyuas seb BEIGGE TIGHNING yog ib qho tsim nyog.
8. Tusluv ntawm ob qho kev txhawb nqa yog 3M, PTFE phaj yuav tsum tau nruab ntawm cov kev txhawb nqa thiabsab nraudyeeb nkab.
Cov ntsiab lus rau kev ua haujlwm & txij nkawm
1. Cov neeg ua haujlwm yuav tsum paub nrog tusua hauj lwmntwss nruab nrab ntawm cov khoom siv hauv cov kab ke. Nws yuav tsum paub tias kua oxygen, ua kua nitrogen thiab kua argon yog cryogenic kua. Thaum lub amnient kub yog siab dua li lub boiling taw tes, lawv yuav yog lawmrojthiab nias tau, ua rau maj mam nce qib hauv lub siab hauvVjp thiab lwm yamkhoom siv.
2. Ua ntej ntawm Vjp ua ntej siv
Txij li thaum tsis siv Vjp yog nyob rau ntawm qhov kub kub, cov yeeb nkab muaj huab cua uas muaj noo noo. Yog li ntawd, lub hom phiaj ntawm kev ua ntej txias yog: ua ntej, kom tsis txhob muaj qhov kub thiab txias ntawm cov pa roj cryogenic nrog cov yeeb nkab kub, ua kom sai Thiab ntau npaum li cas ntawm cov roj av, ua rau muaj kev nias sai li ntawm VJP, yog li ua rau kev puas tsuaj rau VJP thiab cov khoom siv ua kua. Qhov thib ob, yog kom maj mam tshem tawm cov huab cua sab hauv lub vjp thiab kom tsis txhob muaj ntau ntawm cryogenic kua ncaj qha nrog huab cua, ua rau khov thiab thaiv hauv VJP.
Ua ntej rov siv dua ntawm lub nqus plua plav tom qab siv tas los yog tsis muaj kev lag luam, yuav tsum tau ua tiav kom zoo li ntawd nws tsuas yog tom qab nws mus txog lub xeev ua haujlwm.
3Cov. TusTxheej txheem precoolingntawm vjp
Ua ntej, tshuaj xyuas seb lub valves, siab koob ntsuassthiab kev ruaj ntseg valveS etc.Hauv Vjp system muaj nyob rau hauv lub xeev sib raug zoo. Tom qab cov saum toj nokuajyog ua tiav, maj mam qhib lubInlet Valve Vjp Systemthiab vaporize/ Txhawb Nqacov dej ntws tsawg rau hauv cov cua txias kom ua ntej-Txias lubVjprautxog30 feeb. Lub siab nyob hauvVjpFonedates zoo heevLub sijhawm no.Thaum lub siab nyob hauvVjpUa ruaj khov ua ruaj khov, qhov ntim caterus tuaj yeem nce ntxiv nce kom nce mus txog thaum nws ua tau raws li qhov yuav tsum tau ua.(NCO TSEG: Thaum lub sijhawm ua ntej txias, yog lub siab nyob hauvVjpsiab dua qhov tsim qauv tsim tawm,nws yuav tsum tau tam sim ntawdtsumRau Txoj Kev Txoj kev lis ntshav rau Vjp system.MEhanwhile,Tag nrho covqhibib lub dab tsi uas qhib thiab kawsntawm txoj kab kom tso siab.)
4Cov. Slub tsev pheeb suabVjp
Thaum Cheemping Txoj kev lis ntshav, nws yog nruj me ntsis txwv kom kaw qhov qub ntawm ob xaus ntawm VJP system tib lub sijhawm, yog li los tsim lub xeev kaw hauv lubVjpQhov system, ua rau muaj kev kub ntxhov ntawm cov kua uas seem hauv VJPVim tias roj av.
5. Tej thaumDyog li ntawmCryogenicLiquids (LiquidONyeem Tseg Tsuas)
Vim tias hydrocarbons thiab cov seem muaj nyob hauvVjp ntawmCov kua oxygen, Cov tshuaj no yuav muab tso rau sab hauv lub raj xa dej rau lub sijhawm ntev thaum thauj los ntawmVjp.Thaum hydrocarbons tau muab tso rau hauv lub raj hauv cov khoom loj thiab ntev ntev, zoo li cov huab cua sov nce lossis covNtau LawmCov kua pa oxygen yog stoped, cov concentration ntawm hydrocarbons hauvVjpnce, thiab cov tshuaj tiv thaiv nrog cov pa oxygen ntxiv tuaj yeem ua rauanhoob txwvtawm.
6.Kev xyuas ximDkev loj hlobntawm vjp
Hauv txhua tusVjpCov kab ke yuav tsum tau teeb tsa kev nyab xeeb tawm system (nrog rau lub tshuab nyem thiab lub siab ntawm kev qhib siab ntawm cov kev nyab xeeb uas yuav cia li qhib thiab tso lub zog nyob rau lub sijhawm. Tib lub sijhawm, tusqhibLi cas los kuj tseem tuaj yeem qhib manually tso lub siab kom ntseeg tau tias muaj kev nyab xeeb ntawm tag nrho VJP system.
