Kev teeb tsa valve ntawm 10 qhov kev nkag siab yuam kev tsis tuaj yeem tsis quav ntsej lub qhov cua valve installation thiab siv cov teeb meem xav tau kev saib xyuas
Nrog rau kev txhim kho sai ntawm kev siv thev naus laus zis thiab kev tsim kho tshiab, cov ntaub ntawv tseem ceeb uas yuav tsum tau xa mus rau cov kws tshaj lij kev lag luam feem ntau tsis pom. Txawm hais tias cov shortcuts los yog cov txheej txheem ceev tuaj yeem cuam tshuam txog kev siv nyiaj luv luv, lawv qhia tias tsis muaj kev paub dhau los thiab kev nkag siab tag nrho ntawm qhov ua rau lub cev siv tau ntev. Raws li qhov kev paub dhau los, cov npe hauv qab no (tsis muaj qhov tseem ceeb) teev 10 qhov ua tau yooj yim thiab tsis pom kev teeb tsa yuam kev:
Nrog rau kev txhim kho sai ntawm kev siv thev naus laus zis thiab kev tsim kho tshiab, cov ntaub ntawv tseem ceeb uas yuav tsum tau xa mus rau cov kws tshaj lij kev lag luam feem ntau tsis pom. Txawm hais tias cov shortcuts los yog cov txheej txheem ceev tuaj yeem cuam tshuam txog kev siv nyiaj luv luv, lawv qhia tias tsis muaj kev paub dhau los thiab kev nkag siab tag nrho ntawm qhov ua rau lub cev siv tau ntev. Raws li qhov kev paub dhau los, cov npe hauv qab no (tsis muaj qhov tseem ceeb) teev 10 qhov ua tau yooj yim thiab tsis pom kev teeb tsa yuam kev:
1. Bolts ntev dhau lawm
Rau cov bolts ntawm lub valve, tsuas yog ib los yog ob lub xov yuav tsum tshaj cov txiv ntoo. Qhov kev pheej hmoo ntawm kev puas tsuaj lossis corrosion tuaj yeem raug txo. Vim li cas ho yuav lub ntsia liaj qhov rooj ntev dua li qhov koj xav tau? Feem ntau, cov bolts ntev dhau lawm vim tias ib tus neeg tsis muaj sijhawm los xam qhov ntev, lossis tus neeg tsuas tsis quav ntsej qhov kawg qhov tshwm sim zoo li. Qhov no yog tub nkeeg engineering.
2. Tswj valve tsis cais cais
Txawm hais tias qhov kev sib cais valve siv qhov chaw muaj txiaj ntsig, nws yog ib qho tseem ceeb uas yuav tsum tso cai rau cov neeg ua haujlwm ua haujlwm ntawm lub valve thaum xav tau kev saib xyuas. Yog tias qhov chaw txwv, yog tias lub rooj vag valve raug suav tias ntev dhau lawm, tsawg kawg nruab ib lub npauj npaim valve, uas yuav luag tsis muaj qhov chaw. Nco ntsoov tias lawv yooj yim dua rau kev ua haujlwm thiab ua haujlwm tau zoo dua rau kev saib xyuas cov haujlwm thaum koj yuav tsum sawv ntawm lawv rau kev saib xyuas thiab kev ua haujlwm.
3. Tsis muaj qhov ntsuas siab lossis lub cuab yeej raug teeb tsa
Qee qhov kev siv hluav taws xob nyiam ntsuas cov ntsuas ntsuas, thiab cov chaw no feem ntau ua haujlwm zoo ntawm kev muab lawv cov neeg ua haujlwm nrog kev sib txuas rau cov cuab yeej ntsuas, tab sis qee cov khoom siv txawm tias muaj kev cuam tshuam rau mounting accessories. Txawm hais tias tsis tau teev tseg, nws yog tsim los kom pom qhov tseeb ntawm lub valve. Txawm tias muaj kev tswj xyuas thiab kev nrhiav tau cov ntaub ntawv (SCADA) thiab lub peev xwm telemetry, ib tug neeg ntawm ib qho taw tes yuav sawv ntawm ib sab ntawm lub valve thiab yuav tsum pom tias lub siab yog dab tsi, uas yooj yim heev.
4. Qhov chaw teeb tsa me me dhau
Yog tias nws tsis yooj yim rau nruab qhov chaw nres tsheb valve, uas yuav cuam tshuam nrog kev khawb pob zeb, thiab lwm yam, tsis txhob sim txuag tus nqi los ntawm kev ua kom tsawg li tsawg tau. Kev saib xyuas yooj yim tom qab theem yuav nyuaj heev. Tsis tas li ntawd nco ntsoov tias cov cuab yeej siv tau ntev heev, yog li qhov chaw yuav tsum tau teem kom tso cai rau qhov chaw kom cov bolts tau xoob. Koj kuj xav tau qee qhov chaw, uas tso cai rau koj ntxiv cov khoom siv tom qab.
5. Lub sijhawm disassembly tsis suav nrog
Feem ntau ntawm lub sijhawm, cov neeg tsim khoom nkag siab tias koj tsis tuaj yeem txuas txhua yam ua ke hauv ib chav ua vaj tse yam tsis xav tau qee yam kev sib txuas kom tshem tawm qhov chaw ntawm qee qhov chaw yav tom ntej. Yog tias tag nrho cov khoom tau nruj nruj thiab tsis muaj qhov khoob, nws yuav luag tsis tuaj yeem cais lawv. Ob qho tib si groove couplings, flange pob qij txha thiab cov yeeb nkab txuas yog tsim nyog. Nyob rau hauv lub neej yav tom ntej, tej zaum tej zaum yuav tsum tau muab tshem tawm, thiab thaum lub sij hawm qhov no feem ntau tsis yog ib qho kev txhawj xeeb rau tus neeg cog lus installation, nws yuav tsum muaj kev txhawj xeeb rau tus tswv thiab engineer.
6. Nruab qhov concentric txo cov yeeb nkab kab rov tav
Qhov no yuav yog nitpicking, tab sis nws tsim nyog them sai sai rau. Eccentric reducer tuaj yeem ntsia tau kab rov tav. Concentric reducers yog mounted nyob rau hauv kab ntsug. Hauv qee daim ntawv thov uas xav tau kev teeb tsa ntawm kab kab rov tav, eccentric reducers yog siv, tab sis qhov teeb meem no feem ntau cuam tshuam nrog tus nqi: concentric reducers yog pheej yig.
7. Valve qhov dej uas tsis tso dej
Txhua chav ntub dej. Txawm tias thaum lub sij hawm pib lub valve, dej yuav poob rau hauv pem teb ntawm qee qhov taw tes raws li huab cua tau ntws los ntawm lub kaus mom. Txhua tus neeg hauv kev lag luam txhua lub sijhawm tau pom cov dej nyab, tab sis yeej tsis muaj kev zam txim (tshwj tsis yog, qhov tseeb, tag nrho cheeb tsam raug dej nyab, qhov twg koj muaj teeb meem loj dua). Yog tias cov kav dej tsis tuaj yeem ntsia tau, siv lub twj tso kua mis yooj yim, piv txwv li lub hwj huam mov. Lub valve ntab nrog lub ejector yuav ua kom lub chamber qhuav thaum tsis muaj hwj chim.
8. Tsis txhob cais cua
Raws li lub siab poob qis, huab cua yog ntws los ntawm kev ncua thiab hloov mus rau hauv cov yeeb nkab, uas tuaj yeem ua teeb meem hauv qab ntawm lub valve. Ib qho yooj yim los ntshav valve yuav tshem tawm cov huab cua uas tuaj yeem tshwm sim thiab yuav tiv thaiv cov teeb meem hauv qab. Cov hlab ntsha ntawm cov hlab ntsha ntawm cov tswj valve kuj tseem siv tau, vim tias huab cua hauv cov kab qhia yuav ua rau tsis muaj kev ruaj ntseg. Vim li cas ho tsis tshem cov huab cua ua ntej nws mus txog lub valve?
9. Spare connector
Qhov no tej zaum yuav yog ib qho teeb meem me me, tab sis nws yeej ib txwm pab tau kom muaj cov khoom seem hauv cov chav dej ntws thiab cov dej ntws ntawm cov tswj valve. Qhov kev teeb tsa no ua rau kev saib xyuas yav tom ntej, txawm tias nws txuas cov hoses, ntxiv cov chaw taws teeb tswj kom tswj tau li qub lossis ntxiv cov khoom xa mus rau SCADA. Rau tus nqi me me ntawm kev ntxiv cov khoom siv ntawm cov qauv tsim, nws ua rau kom muaj txiaj ntsig zoo rau yav tom ntej. Ua rau kev saib xyuas cov haujlwm nyuaj dua vim tias txhua yam yog cov xim pleev xim thiab yog li cov ntawv teev npe tsis tuaj yeem nyeem lossis hloov kho.
10. Nco ntsoov: Ua tej yam uas yog txoj kev yeej ib txwm ua pov thawj tias muaj txiaj ntsig, tab sis kev luv luv feem ntau ua rau muaj teeb meem ntau dua. Txawm hais tias 10 cov ntsiab lus no tej zaum yuav suav tias yog xaiv heev los ntawm qee tus, ib tug xibhwb laus uas txawj ntse tau hais rau kuv tias, “Thaum koj chew nqaij, ntuav cov pob txha.
Cov lus ceeb toom rau kev teeb tsa thiab siv lub qhov cua valve Kev teeb tsa thiab siv cov kev cai:
1, lub valve chamber yuav tsum tau ntxuav ua ntej kev teeb tsa, thiab cov teeb meem tshwm sim hauv kev thauj mus los;
2, vent valve installation yuav tsum ua kom tus npauj npaim valve tsav ncej yog kab rov tav, lub piston valve ntsug upward txoj hauj lwm;
3. Ua ntej siv lub valve, cov cuab yeej sib kis yuav tsum tau hloov kho kom lub zog ntawm cov khoom sib kis tsis zoo, thiab kev txwv tsis pub muaj zog thiab kev tiv thaiv kev tiv thaiv ntau dhau yog txhim khu kev qha;
4, lub valve kis tau tus mob lubrication qhov chaw ua ntej commissioning tag nrho ntxiv lubricating roj;
5. Ua ntej pib lub tshuab hluav taws xob, ua tib zoo nyeem phau ntawv qhia ntawm lub tshuab hluav taws xob uas muab rau nws.
Kev pabcuam thiab kho
1. Saib xyuas qhov qhib thiab kaw ntawm lub valve tsis tu ncua tom qab siv, thiab daws cov teeb meem hauv lub sijhawm;
2. Sau cov roj lubricating tsis tu ncua kom tswj tau cov roj lubrication zoo ntawm txhua qhov chaw txav;
3. Tom qab siv rau ib lub sijhawm, yog tias pom tias lub piston tsis nruj nruj, lub nplhaib piston yuav tsum tau kuaj xyuas thiab hloov.
