I. Kev Saib Xyuas Kev Ua Haujlwm Txhua Hnub: Cov Khoom Siv "Tus Kheej-Tswb"
Qhov no yog txoj hauv kev ncaj qha tshaj plaws los txiav txim qhov xwm txheej. Thaum lub sijhawm ua haujlwm, ua tib zoo saib xyuas cov kev txwv thiab qhov tshwm sim hauv qab no:
1. Qhov kub thiab txias tsis zoo: Cov kev hloov pauv txawv txav los yog sib txawv ntawm qhov teeb tsa ntawm lub tshuab ziab khaub ncaws kub lossis cua sov nruab nrab (steam / heat transfer oil) siab yuav qhia tau tias qhov ntsuas kub ntawm qhov chaw cua sov, dej ntws, los yog lub tshuab nqus tsev vacuum.
2. Kev nrawm nrawm thiab Load: Tsis ruaj khov paddle ceev, nce kev hloov pauv, lossis qhov txawv txav ntawm lub cev muaj zog tam sim no feem ntau qhia txog cov khoom siv agglomeration, paddle jamming, los yog muaj kev sib txhuam ntau ntxiv vim cov kabmob hnav.
3. Cov suab nrov tsis zoo thiab kev vibrations: hnov lub suab sib txhuam ntawm cov hlau, cov suab nrov, lossis lub suab nrov nrov thaum lub sijhawm ua haujlwm, nrog rau cov cuab yeej txawv txav kev co, feem ntau yog lub teeb liab pom tseeb ntawm kev puas tsuaj, tsis zoo iav meshing, los yog kev sib txhuam ntawm lub paddle thiab lub tog raj kheej.
4. Cov cim qhia txog kev Leakage: Txheeb xyuas qhov kawg ntawm qhov kawg, qhov nkag, qhov hluav taws xob, thiab cov yeeb nkab sib txuas rau cov khoom xau, cov pa xau, los yog lubricating roj seepage. Kev saib xyuas yog xav tau thaum pom cov roj stains, dej stains, los yog tsw ntxhiab tsw txawv txawv (xws li cov pa xau).
II. Kev tshuaj xyuas thiab tu tsis tu ncua: Ua kom pom cov teeb meem muaj peev xwm
Raws li txoj kev npaj tu, tsis tu ncua xyuas cov khoom tseem ceeb; Nov yog lub hauv paus ntawm kev tiv thaiv malfunctions:
1. Impeller Inspection: impellers tuaj rau hauv kev sib cuag nrog cov ntaub ntawv ncaj qha thiab nquag hnav thiab corrosion. Tshawb xyuas cov impellers rau deformation, ceev hnav, corrosion, los yog txheej tev tawm. Hnyav hnav impellers yuav cuam tshuam kev ua haujlwm ntawm kev sib tw thiab kev hloov hluav taws xob.
2. Kev Kho Mob thiab Foob:
Bearings: Tsis tu ncua xyuas cov kabmob kub (hnyav ntau dhau qhia tias tsis txaus lubrication lossis kev puas tsuaj) thiab lubrication mob, thiab rov ntxiv lossis hloov roj raws li xav tau. Disassemble, huv si, thiab hloov cov roj rau peb lub hlis twg los yog raws li cov sijhawm ua haujlwm.
Cov ntsaws ruaj ruaj: Tshawb xyuas lub qhov kawg ntawm lub tshuab foob, ntim cov foob, thiab cov khoom siv hluav taws xob / qhov hluav taws xob rau kev laus, hnav, lossis tsis tuaj yeem tiv thaiv cov khoom xau thiab nkag mus ntawm cov khoom tsis zoo sab nraud.
3. Kev tshuaj xyuas qhov system kis tau tus mob: xyuas lub lubrication, meshing, nruj, thiab tej yam txawv txav ntawm lub reducer, coupling, gears, thiab saw. Hais txog txhua yam teeb meem tam sim ntawd, xws li qib roj tsis txaus lossis roj tsis zoo.
4. Kev kho cua sov:
Chav Cua Kub: Tshawb xyuas cov kav dej, cov li qub, thiab cov twj tso kua mis rau kev ua haujlwm kom raug thiab xau. Ntxuav cov lim tsis tu ncua kom tsis txhob txhaws.
Thaum tshav kub kub hloov roj cua sov: Saib xyuas cov cua kub hloov roj theem, kub, thiab zoo. Nqa cov qauv rau kev sim tsis tu ncua thiab hloov cov roj raws li xav tau.
5. Kev tu thiab tu: Tom qab txhua qhov kaw, cia cov khoom siv kom txias (xws li, qis dua 50℃). Ua tib zoo ntxuav cov phab ntsa sab hauv ntawm lub tog raj kheej, qhov chaw ntawm lub impeller, thiab qhov nkag / qhov hluav taws xob kom tshem tawm cov khoom seem, tiv thaiv clumping, corrosion, thiab cross- paug. Tsis tu ncua ntxuav lub tshav kub hloov nruab nrab lim thiab inlet cua lim.
III. Tsim thiab ua raws li cov phiaj xwm kev kho
1. Tsim ib Daim Ntawv Teev Tseg: Sau lub sijhawm, cov ntsiab lus, hloov qhov chaw, cov teeb meem pom, thiab cov kev daws teeb meem rau txhua qhov kev saib xyuas. Qhov no ua kom yooj yim rau kev txheeb xyuas cov khoom siv thiab kev kwv yees txog kev xav tau kev saib xyuas yav tom ntej.
2. Tiered Maintenance System:
Kev Kho Txhua Hnub: Ua txhua hnub los ntawm cov neeg ua haujlwm, suav nrog kev kuaj xyuas qhov chaw, tu, thiab lubrication yooj yim.
Kev Kho Lub Sij Hawm Lub Sij Hawm (Major/Minor Overhauls): Tsim cov phiaj xwm raws li lub sijhawm ua haujlwm (piv txwv li, txhua 500 teev, 2000 teev) kom paub ntau ntxiv hauv -kev tshuaj xyuas qhov tob, kev hloov kho, hloov cov khoom hnav, thiab kev tu lub cev.
3. Overhaul: Ua raws li cov khoom siv lifespan (piv txwv li, txhua txhua 3-5 xyoos) lossis kev soj ntsuam cov khoom siv. Yuav tsum tau ua kom tiav disassembly thiab tshuaj xyuas, thiab hloov tag nrho cov khoom hnav.
IV. Kev cuam tshuam ntawm cov khoom siv thiab kev ua haujlwm
1. Khoom siv ua ntej-kev kho mob: xyuas kom meej tias cov khoom noj me me thiab cov dej noo raws li cov khoom siv, tiv thaiv cov khoom tawv loj lossis cov hlau tsis huv los ntawm kev nkag mus. Qhov no yog ib kauj ruam tseem ceeb hauv kev tiv thaiv lub impeller thiab lub tog raj kheej.
2. Kev ua haujlwm tau zoo: Tsis txhob overloading (tus nqi thauj khoom raug pom zoo kom tsis pub tshaj 105% ntawm tus nqi ntsuas), tswj kev pub noj ceev, thiab tiv thaiv cov khoom siv tsis zoo vim yog overload lossis txhaws.
