Cov Kev Ceeb Toom Installation
The VJP(Lub tshuab nqus tsev vacuum piping)yuav tsum tau muab tso rau hauv qhov chaw qhuav tsis muaj cua ua ntej kev teeb tsa.Covsab nrauvntimtxheej ntawm VJP tsis tuaj yeembe qhibed, txhawm rau tiv thaiv lub raj rau hauv lub cev txawv teb chaws (xuab zeb, cov kab mob me me, thiab lwm yam). Thaum los nag los yog ntevntubhuab cua, kuj yuav tsum tau them tshwj xeeb mloog mus rau sab hauv ntawm lub raj xa dej tsis muaj dej.
Nws yog txwv tsis pub siv VJP ncaj qha raws li vuam electrode, ntaus arclos yog vuam ntawm VJP.
The VJPntimtxheej tsis tuaj yeem raug tshem tawm kom txog thaum cov yeeb nkab tau teeb tsa los tiv thaiv kev tawg ntawm vuam hauv lwm txoj haujlwm.
Thaum lub sij hawm tag nrho cov txheej txheem installation, VJP yuav tsum tau ua tib zoo saib xyuas. Tiv thaiv ob qhov kawgntawm VJP, tsis txhob siv lublub tshuab nqus tsevsib koom ua ke ntawm VJP (daim duab 1 thiab 3) raws li lub ntsiab lus ntawm kev quab yuam kom tiv thaiv kom tsis txhob muaj lub tshuab nqus tsev.
Thaum txhim kho, xyuam xim rau kev ntseeg siab ntawm hoisting, tsis txhob poob thiab puas los yog raug mob.
Cov kauj ruam installation ntawm VJP
1. Tshawb xyuastusdaim duabs, seb qhov ntau npaum li cas thiab dimensionntawm lub cevntawm cov duab kos yog tib yamnrogtuscev flo. Bua ntej installation, nrhiavtawmtxhua VJP raws li daim duab thiabtus lej. Piv txwv:HL2018GLN-59-02-01, uas txhais tau hais tias qhov project code yog 59, kua nitrogen nruab nrab, yeeb nkabTsis muaj.01 liyTsis muaj.02. Ib daim ntawv hlau nrog qhov notus lejyog txuas nrog VJP ntawm qhov chaw (daim duab 1), thiab txuas nrog lub npe hluav taws xob hluav taws xobnyob ze ntawm lub tshuab nqus tsev sib txuas rautusVJP(daim duab 2).
Nco tseg: lubkom muaj nuj nqisthiab Tsis muaj.ntawm cov kav dej hauv daim duab yuav tsum yog tib yam li covkom muaj nuj nqisthiabTsis muaj.ntawmVJPsntawm qhov chaw. Yog tias muaj qhov tsis sib xws hauv kev kuaj xyuas, nco ntsoov tiv tauj peb cov neeg ua haujlwm ntawm qhov chaw.
2. Tom qab kuaj xyuas VJP kom muaj nuj nqis thiabTsis muaj.,raws li cov duab kos, txavlub VJPsntawm qhov sib txuass/kev txhawb nqalos yog qhov chawVJPsnyob rau hauv pem hauv ntej ntawm tus coj brackets/kev txhawb nqa.
3. Ua ntej cov flanges txuas, ua ntej xyuas seb lub nplhaib foob thiab lub foob txias puas raug ntsia tau zoo
4. Ntxuav cov pob qij txha ntawmpoj niam & txiv neejtxuas ntxivcev, foobnplhaibthiab txias foob chav tsev nrog roj-dawb thiab dej-dawb reagent.
5. Ntxig tus txiv neej thiab poj niam extension yeeb nkab horizontally thiab maj mam. Tom qab ntawd rub ob lub flanges ua ke thiab nias, thiab nruab tag nrho cov bolts ntawm flanges (tsis txhob nruj tam sim no).
6. Tom qab ua kom paub tseeb qhov tseeb ntawm ob lub flanges, ceev cov bolts ib kauj ruam. Xyuas kom meej tias lub flange khaws cia theem thaum lub sij hawm installation
7. Xyuas seb qhov flange zawm puas tsim nyog.
8. CovLub sijhawm ntawm ob qho kev txhawb nqa yog 3m, PTFE phaj yuav tsum tau nruab ntawm qhov kev txhawb nqa thiabsab nrauvcev.
Paub meej rau Kev Ua Haujlwm & Kev Kho
1. Cov neeg ua haujlwm yuav tsum paub txog covua haujlwmntwss nruab nrab ntawm cov khoom siv hauv qhov system. Nws yuav tsum paub tias kua oxygen, kua nitrogen thiab kua argon yog cov kua cryogenic. Thaum lub ambient kub siab tshaj qhov boiling point, lawv yuav lawmgasifythiab pressurized, uas ua rau ib tug maj mam nce nyob rau hauv lub siab nyob rau hauv lubVJP thiab lwm yamkhoom siv.
2. Precooling ntawm VJP ua ntej siv
Txij li thaum tsis siv VJP yog nyob rau ntawm qhov kub thiab txias, cov yeeb nkab tau ntim nrog cua uas muaj cov dej noo. Yog li ntawd, lub hom phiaj ntawm kev ua ntej txias yog: ua ntej, maj mam txo qhov kub ntawm VJP mus rau qhov kub ntawm cov kua cryogenic, kom tsis txhob muaj kev sib cuag ncaj qha ntawm cov kua cryogenic ntau nrog cov kav dej kub ib txwm, ua kom sai. thiab loj npaum li cas ntawm gasification, ua rau kom ceev ceev ceev ntawm VJP, yog li ua rau kev puas tsuaj rau VJP thiab lub davhlau ya nyob twg cov khoom ua kua. Qhov thib ob, yog kom maj mam tshem tawm cov huab cua hauv VJP thiab kom tsis txhob muaj ntau cov kua cryogenic sib cuag nrog huab cua, uas ua rau khov thiab txhaws hauv VJP.
Ua ntej rov siv lub tshuab nqus tsev adiabatic yeeb nkab tom qab thawj zaug siv lossis nres ntau lawm, precooling yuav tsum tau nqa tawm kom lub tshuab nqus tsev adiabatic yeeb nkab tuaj yeem ua haujlwm ib txwm tsuas yog tom qab nws mus txog lub xeev ua haujlwm.
3. CovTxoj kev Precoolingntawm VJP
Ua ntej, xyuas seb lub valves, siab gaugesthiab kev nyab xeeb valves lwm.nyob rau hauv lub VJP system yog nyob rau hauv tus coj lub xeev. Tom qab qhov saum toj nokuajua tiav, maj mam qhib lubinlet valve ntawm VJP systemthiab vaporize/gasifycov kua dej qis rau hauv cov cua txias kom ua ntej-cool covVJPrautxog30 feeb. Lub siab nyob rau hauv lubVJPfluctuates heevlub sijhawm no.Thaum lub siab nyob rau hauv lubVJPua kom ruaj khov, qhov ntim infusion tuaj yeem maj mam nce mus txog thaum nws ua tau raws li qhov yuav tsum tau ua.(Nco tseg: thaum lub sij hawm ua ntej-txias txheej txheem, yog hais tias lub siab nyob rau hauv lubVJPyog siab tshaj qhov sib thooj tsim siab,nws yuav tsum tam sim ntawdnresinfusion rau VJP system.Mtib lub sijhawm,kiag li qhib lubqhov cuavalvesntawm kab kom tso siab.)
4. Stsev pheeb suabVJP
Thaum tso tseg cov dej haus, nws yog txwv tsis pub kaw lub valve ntawm ob qhov kawg ntawm VJP system tib lub sijhawm, txhawm rau tsim lub xeev kaw hauvVJPsystem, ua rau overpressure ntawm cov kua seem hauv VJPvim gasification.
5. Lub caij nyoogDischarge ntawmCryogenicLiquids (LiquidOxygen xwb)
Vim muaj hydrocarbons thiab residues nyob rau hauvVJP ntawmcov kua oxygen, cov tshuaj no yuav muab tso rau hauv lub raj xa dej rau lub sijhawm ntev thaum thauj los ntawmVJP.Thaum cov hydrocarbons tso rau hauv lub raj hauv qhov ntau thiab ntev, raws li huab cua sov los yogntau lawmkua oxygen yog stopped ua, qhov concentration ntawm hydrocarbons nyob rau hauv lubVJPnce, thiab cov tshuaj tiv thaiv nrog cov pa oxygen ntxiv tuaj yeem ua rauanexplosion.
6.Kev nyab xeebDevicentawm VJP
Hauv txhua qhovVJPlub kaw lus yuav tsum tau teeb tsa kev nyab xeeb tso tawm (suav nrog lub valve nyem thiab lub qhov cua), Thaum lub siab ntawm VJP mus txog qhov qhib siab ntawm qhov kev nyab xeeb li qub uas yuav cia li qhib thiab tso tawm lub siab raws sijhawm. Nyob rau tib lub sijhawm, lubqhov cuali qub tseem tuaj yeem qhib manually los tso tawm lub siab kom muaj kev nyab xeeb ntawm tag nrho VJP system.
