Rau qhovli qubhauv kev ua haujlwm, txhua yamvalvecov khoom yuav tsum ua kom tiav thiab tsis zoo. Cov bolts ntawm lub flange thiab lub bracket yog qhov tseem ceeb, thiab cov xov yuav tsum tau zoo thiab tsis tso cai rau xoob. Yog hais tias lub fastening txiv ntseej ntawm lub handwheel pom tias yog xoob, nws yuav tsum tau nruj me ntsis nyob rau hauv lub sij hawm kom tsis txhob ua puas ntawm lub pob qij txha los yog poob ntawm lub handwheel thiab nameplate. Yog hais tias lub handwheel ploj lawm, nws tsis raug tso cai los hloov nws nrog ib tug adjustable ciaj ntswj, thiab nws yuav tsum tau ua kom tiav raws sij hawm. Lub packing caj pas tsis raug tso cai rau skewed los yog tsis muaj pre-tightening qhov sib txawv. Rauli qubnyob rau hauv ib qho chaw uas yooj yim kis los ntawm nag, daus, plua plav, cua thiab xuab zeb, lub qia valve yuav tsum tau nruab nrog lub hau tiv thaiv. Qhov ntsuas ntawm lub valve yuav tsum tau khaws cia kom zoo, raug thiab meej. Cov ntsaws ruaj ruaj, lub kaus mom thiab cov khoom siv pneumatic ntawm lub valve yuav tsum ua kom tiav thiab tsis zoo. Lub tsho rwb thaiv tsev yuav tsum tsis muaj dents lossis tawg.
Nws tsis raug tso cai rau khob, sawv ntsug lossis txhawb nqa cov khoom hnyav ntawm lub valve hauv kev ua haujlwm; tshwj xeeb tshaj yog non-metallic li qub thiabcam khwb cia hlau li qubtseem txwv tsis pub.
Kev kho ntawm idleli qub
Kev saib xyuas ntawm lub valve yuav tsum tau ua ua ke nrog cov khoom siv thiab cov kav dej, thiab cov haujlwm hauv qab no yuav tsum tau ua:
1. Ntxuav lubvalve
Lub puab kab noj hniav ntawm lub valve yuav tsum tau purged thiab ntxuav tsis muaj residue thiab aqueous tov, thiab sab nrauv ntawm lub valve yuav tsum tau wiped huv si tsis muaj av, roj,
2. Teem lubvalventu
Tom qab lubvalveyog ploj lawm, sab hnub tuaj tsis tuaj yeem disassembled los ua rau sab hnub poob, thiab cov khoom siv valve yuav tsum tau ua kom tiav los tsim cov kev mob zoo rau kev siv tom ntej thiab xyuas kom meej tias cov khoom siv tau zoo.valvenyob zoo.
3. Kev tiv thaiv corrosion
Tshem tawm cov ntim rau hauv lub thawv ntim khoom kom tiv thaiv kev xeb ntawm galvanicvalveqia. Siv cov tshuaj tiv thaiv kab mob thiab roj rau lub valve sealing nto,valveqia, valve qia txiv ntoo, machined nto thiab lwm qhov chaw raws li qhov xwm txheej tshwj xeeb; cov xim pleev xim rau qhov chaw yuav tsum tau pleev xim rau cov xim tiv thaiv corrosion.
4. Kev tiv thaiv
Txhawm rau tiv thaiv kev cuam tshuam ntawm lwm yam khoom, tus neeg tsim kev tuav thiab disassembly, yog tias tsim nyog, cov khoom txav ntawm lub valve yuav tsum tau kho, thiab lub valve yuav tsum tau ntim thiab tiv thaiv.
5.kev saib xyuas tsis tu ncua
Valvesuas tau ua haujlwm ntev ntev yuav tsum tau kuaj xyuas thiab khaws cia tsis tu ncua kom tiv thaiv corrosion thiab kev puas tsuaj rau lubvalve. Rauli qubuas tau ua haujlwm ntev dhau lawm, lawv yuav tsum tau siv tom qab dhau qhov kev sim siab ua ke nrog cov khoom siv, cov khoom siv, thiab cov kav dej.
Kev tu cov khoom siv hluav taws xob
Kev tu txhua hnub ntawm cov cuab yeej hluav taws xob feem ntau tsis pub tsawg dua ib hlis ib zaug. Cov ntsiab lus ntawm kev kho yog:
1. Cov tsos yog huv si tsis muaj plua plav; cov cuab yeej tsis muaj paug los ntawm chav dej, dej thiab roj.
2. Cov khoom siv hluav taws xob tau raug kaw zoo, thiab txhua qhov sealing nto thiab taw tes yuav tsum ua kom tiav, ruaj khov, nruj, thiab tsis muaj paug.
3. Lub tshuab hluav taws xob yuav tsum tau lubricated zoo, oiled raws sij hawm thiab raws li xav tau, thiab lub valve qia txiv ntoo yuav tsum tau lubricated.
4. Cov khoom siv hluav taws xob yuav tsum nyob rau hauv qhov zoo, thiab zam kev ya raws ntawm cov av noo thiab hmoov av; yog tias nws ntub dej, siv 500V megohmmeter los ntsuas qhov kev tiv thaiv hluav taws xob ntawm txhua qhov tam sim no-nqa thiab lub plhaub, thiab tus nqi yuav tsum tsis txhob qis dua o. Rau ziab.
5. Lub tshuab hluav taws xob tsis siv neeg hloov pauv thiab thermal relay yuav tsum tsis txhob mus, qhov taw qhia lub teeb qhia kom raug, thiab tsis muaj kev poob qis, luv Circuit Court lossis qhib Circuit Court.
6. Cov xwm txheej ua haujlwm ntawm lub tshuab hluav taws xob yog qhov qub, thiab qhov qhib thiab kaw yog hloov tau.
Kev tu cov khoom siv pneumatic
Kev tu txhua hnub ntawm cov cuab yeej pneumatic feem ntau tsis pub tsawg dua ib hlis ib zaug. Cov ntsiab lus tseem ceeb ntawm kev saib xyuas yog:
1. Cov tsos yog huv si tsis muaj plua plav; cov cuab yeej yuav tsum tsis txhob muaj dej vapor, dej thiab roj.
2. Lub sealing ntawm lub tshuab pneumatic yuav tsum zoo, thiab cov sealing nto thiab cov ntsiab lus yuav tsum ua kom tiav thiab ruaj khov, nruj thiab tsis muaj kev puas tsuaj.
3. Cov txheej txheem kev khiav hauj lwm yuav tsum tau lubricated zoo thiab qhib thiab kaw tau yooj yim.
4. Lub qhov hluav taws xob thiab qhov hluav taws xob sib txuas ntawm lub tog raj kheej tsis pub ua kom puas; txhua qhov chaw ntawm lub tog raj kheej thiab cov kav dej cua yuav tsum tau ua tib zoo tshuaj xyuas, thiab yuav tsum tsis txhob muaj qhov xau uas cuam tshuam rau kev ua haujlwm.
5. Cov yeeb nkab tsis raug tso cai rau sunken, lub annunciator yuav tsum nyob rau hauv zoo, qhov taw qhia lub teeb ntawm lub annunciator yuav tsum nyob rau hauv zoo, thiab cov xov txuas ntawm lub pneumatic annunciator los yog hluav taws xob annunciator yuav tsum tau zoo tsis muaj to.
6. Covvalves ntawm lub tshuab pneumatic yuav tsum nyob rau hauv qhov zoo, tsis muaj qhov to, qhib tau yooj yim, thiab muaj huab cua zoo.
7. Tag nrho cov cuab yeej pneumatic yuav tsum nyob rau hauv ib txwm ua haujlwm, qhib thiab kaw yooj yim.
