Kev khaws cia kom zoo thiab kev saib xyuas ntawm lub qhov rooj qub qub yog qhov tseem ceeb los xyuas kom lub sijhawm ntev - kev cia siab rau hauv kev tiv thaiv hluav taws, cov kav dej hauv nroog, thiab cov kav dej ua lag luam. Txawm tias tsim nyob rau hauv API 600 los yog EN 1171, lub rooj vag li qub yuav tsum tau tiv thaiv los ntawm corrosion, mechanical puas, thiab foob deterioration thaum lub sij hawm cia. Kev tuav kom raug ua kom lub valve ua haujlwm zoo thiab ua haujlwm tau zoo thaum kawg nruab.
Vim li cas Kev Cia Siab Ntawm Qhov Rooj Valves Matters
Backup gate li qub feem ntau khaws cia rau lub hlis lossis xyoo ua ntej kev teeb tsa. Yog tias tsis muaj kev tswj hwm ib puag ncig zoo, lawv tuaj yeem txhim kho:
Nto xeb lossis sab hauv corrosion
Lub rooj zaum deformation
qia qaug dab peg vim tsis muaj lubrication
Flange ntsej muag puas
Elastomer foob degradation
Kev cia khoom tsis zoo tuaj yeem txo cov kev pabcuam lub neej txawm tias ua ntej lub valve nkag mus rau kev ua haujlwm.
Qhov zoo tshaj plaws cia cov xwm txheej rau thaub qab rooj vag li qub
Khaws sab hauv tsev hauv qhov chaw tswj tau
Khaws cov li qub nyob rau hauv qhov chaw qhuav, zoo -ventilated warehouse
Tsis txhob raug los nag, tshav ntuj, thiab cov av noo siab
Khaws qhov ntsuas kub kom ruaj khov
Khaws kom deb ntawm cov tshuaj corrosive
Yog tias qhov chaw cia sab nraum zoov tsis tuaj yeem zam tau, tsa cov li qub saum toj no hauv av thiab siv cov npog tiv thaiv dej.
Khaws Cov Ncauj Tiv Thaiv Kom Zoo
Tsis txhob tshem tawm:
Flange tiv thaiv
Xov caps
Xaus npog
Cov khoom no tiv thaiv plua plav, khib nyiab, thiab ya raws nkag mus rau hauv lub cev valve.
Kho qhov chaw thiab stacking
Khaws cov valve hauv qhovkaw tag nrho txoj hauj lwm
Siv pallets lossis ntoo txhawb nqa
Tsis txhob stacking hnyav li qub ncaj qha rau saum ib leeg
Qhov loj - qhov ntev li qub yuav tsum tau khaws cia ncaj thaum ua tau
Qhov chaw kom raug tiv thaiv kev ntxhov siab ntawm cov neeg kho tshuab thiab sealing nto puas.
Routine Inspection of Stored Gate Valves
Txawm tias cov ntaub ntawv thaub qab yuav tsum tau tshuaj xyuas tas li.
Pom zoo daim ntawv tshuaj ntsuam xyuas
Tshawb xyuas cov txheej txheem txheej thiab saib rau xeb
Tshawb xyuas flange ntsej muag rau khawb lossis dents
Xyuas kom cov kaus mom tiv thaiv muaj kev ruaj ntseg
Paub meej tias qhuav cia tej yam kev mob
Yog tias kuaj pom muaj corrosion, ntxuav qhov chaw cuam tshuam thiab rov siv tshuaj tiv thaiv -corrosion txheej tam sim ntawd.
Stem Lubrication thiab Mechanical Care
Lub valve qia yog ib qho tseem ceeb ntawm kev txav mus los.
Siv cov chaw tsim khoom- pom zoo cov roj nplua nyeem ib ntus
Maj mam tig lub tes tuav ib ntus kom tsis txhob lo
Tsis txhob tag nrho lub voj voog lub valve tsis tsim nyog
Kev lubrication kom zoo tiv thaiv kev khi thaum ua haujlwm.
Tiv thaiv cov ntsaws ruaj ruaj thiab Gaskets
Roj hmab thiab elastomer Cheebtsam tuaj yeem degrade raws sijhawm.
Tsis txhob raug kub kub
Khaws cov li qub kom deb ntawm ozone- cov cuab yeej tsim khoom
Ua kom ruaj khov hauv tsev
Yog tias khaws cia ntev - lub sijhawm, cov ntsaws ruaj ruaj yuav tsum tau kuaj xyuas ua ntej kev teeb tsa.
Ua ntej-Kev kuaj xyuas
Ua ntej txhim kho lub rooj vag valve:
Tshem cov npog tiv thaiv
Tshawb xyuas flange sealing nto
Tshawb xyuas qia ua haujlwm kom zoo txav
Txheeb xyuas qhov ntsuas siab thiab qhov tshwj xeeb
Paub meej tias txheej kev ncaj ncees
Kev tshuaj xyuas zaum kawg ua kom muaj kev npaj txhij rau kev ua haujlwm nyab xeeb.
Kev tswj cov khoom thiab cov ntaub ntawv
Ua kom tiav cov ntaub ntawv suav nrog:
Chaw tsim tshuaj paus thiab qauv
Valve loj thiab siab ntsuas
Hnub pib cia
Kev tshuaj xyuas thiab kev saib xyuas keeb kwm
Kev siv thawj zaug -Nyob rau hauv, Ua ntej- Tawm (FIFO) system tiv thaiv kev laus dhau ntawm cov khoom thaub qab.
Xaus
Kev khaws cia kom zoo thiab kev saib xyuas ntawm cov rooj vag thaub qab tiv thaiv koj cov peev nyiaj thiab ua kom muaj kev ntseeg siab ua haujlwm. Los ntawm kev tswj hwm ib puag ncig ib puag ncig, ua qhov kev tshuaj ntsuam xyuas ib ntus, thiab tswj xyuas kom zoo lubrication, li qub tseem ua haujlwm tau zoo thaum xav tau rau kev tiv thaiv hluav taws tseem ceeb thiab kev faib dej.
