1. Kev kuaj mob qhov ua rau ntawm kev xau
Ua ntej tshaj plaws, nws yog qhov tsim nyog los kuaj xyuas qhov ua rau muaj kev xau. Cov dej xau tuaj yeem tshwm sim los ntawm ntau yam ntawm ntau yam, xws li frayed sealing surfaces, deterioration ntawm cov ntaub ntawv, kev teeb tsa tsis raug, cov neeg tsav tsheb yuam kev, lossis xov tooj corrosion. Lub hauv paus ntawm cov dej xau tuaj yeem tau ntsuas cov cuab yeej sai li ultrasonic cov txheej txheem kuaj, kuaj pom kev ua kom pom kev rau kev kho tom ntej.
Qhov thib ob, kev daws rau kev sib txawv
1. Lub pob kaw poob thiab ua rau muaj kev rwj
Cov laj thawj: kev ua haujlwm tsis zoo ua rau cov khoom kaw kom raug daig lossis siab tshaj lub chaw tuag loj, thiab kev sib txuas yog puas thiab tawg; Cov khoom siv ntawm cov kev xaiv txuas tsis yog lawm, thiab nws tsis tuaj yeem tiv thaiv cov corrosion ntawm nruab nrab thiab hnav ntawm cov tshuab.
Kev daws: Ua haujlwm rau lub valve kom raug zam dhau kev quab yuam ua rau cov khoom kaw kom raug daig lossis puas; Nquag xyuas seb qhov kev sib txuas tsis tu ncua ntawm lub kaw thiab lub valve kav yog khov kho, thiab hloov qhov kev sib txuas hauv lub sijhawm yog tias muaj corrosion lossis hnav; Xaiv cov khoom siv ntawm cov txuas nrog zoo corrosion tsis kam thiab hnav tsis kam.
2. Txia ntawm lub hlws ris ntawm cov nplhaib sib khi
Yog vim li cas: lub nplhaib sib khi tsis nruj ntom nti; Neeg tsis zoo vuam zoo ntawm lub nplhaib sib khi thiab lub cev; Sib sau xov thiab screws yog xoob lossis corroded.
Kev daws: Siv cov nplaum los txhim kho qhov chaw dov ntawm lub nplhaib sib khi; Kho thiab rov muab Weld cov kev tsis xws luag; Raws sij hawm hloov ntawm corroded lossis puas xov thiab screws; Rov muab weld cov hlws sib xyaw raws li cov lus qhia tshwj xeeb.
3. Txhaum ntawm lub cev valve thiab kaus mom
Vim li cas: lub casting zoo ntawm hlau castings yog tsis siab, thiab muaj qhov tsis xws luag xws li cov xuab zeb, xoob cov ntaub, thiab hlais slag; hnub khov tawg; Tsis zoo vuam, nrog cov tsis xws luag xws li swb swb, unwelding, kev nyuaj siab tawg, thiab lwm yam; Lub valve tau puas tom qab raug ntaus los ntawm ib qho khoom hnyav.
Kev daws: Txhim kho qhov cam khwb zoo thiab ua kom muaj zog kuaj ua ntej kev teeb tsa; Lub valve nrog tsawg qhov kub yuav tsum tau insulated lossis kub-tov, thiab lub valve uas tawm ntawm kev siv yuav tsum tau nqus dej ntawm cov dej khov; WELD nyob rau hauv raws li cov kab kev ua haujlwm ua haujlwm, thiab nqa tawm cov txheej txheem thaiv thiab kev ntsuam xyuas thiab kev sim ua kom muaj zog; Nws yog txwv tsis pub thawb thiab muab cov khoom hnyav ntawm lub valve, thiab zam kev tsoo cov cam khwb cia hlau thiab tsis yog xim hlau li qub nrog lub rauj.
4. Txhob ntawm kev sib khi saum npoo
Cause: Tsis sib tsoo sib tsoo ntawm cov chaw sib khi; Kev sib txuas ntawm lub qia thiab lub shut-off yog dai, tsis raug cai lossis hnav; bent los yog missassembled stems; Tsis tsim nyog xaiv ntawm sealing nto khoom.
Kev daws: Kev xaiv kom raug ntawm gasket khoom thiab ntaus raws li kev ua haujlwm; Ua tib zoo kho lub valve kom ntseeg tau tias txoj haujlwm du; Zawm rau lub ntsia liaj qhov rooj caj dab thiab cov cim ua ke, thiab siv lub zog ua kom meej kom ntseeg tau tias kev yuav tsum tau ua; Kho, sib tsoo thiab xim tshuaj xyuas cov chaw zoo li qub los xyuas kom meej tias lawv tau raws li cov cai muaj feem xyuam; Ua tib zoo saib thaum txhim kho lub gasket kom tsis txhob muaj gasket poob rau hauv av.
5. Txhaum ntawm cov muab tub lim
Vim li cas: xaiv tsis raug cai ntawm muab tub lim; Cov khoom siv tsis raug; kev laus ntawm fillers; Qhov tseeb ntawm lub qia yog tsis siab; Cov qog, bolts thiab lwm qhov chaw raug puas ntsoog.
Kev daws: Xaiv cov khoom ntim khoom uas tsim nyog thiab ntaus raws li cov haujlwm ua haujlwm; Kev tsim kho kom zoo ntawm cov lus qhia tshwj xeeb; Hloov cov laus thiab ua kom haum rau lub sijhawm; Ncaj, kho lossis hloov khoov, hnav cov kav; Cov qog puas, bolts thiab lwm yam yuav tsum tau kho lossis hloov sijhawm; Ua raws li cov txheej txheem ua haujlwm thiab ua haujlwm lub valve ntawm qhov nrawm thiab kev quab yuam ua ib txwm muaj.
3. Kev tiv thaiv kev ntsuas
1. Kev tshuaj xyuas thiab kev tu ib txwm muaj: kev npaj ua haujlwm tsim nyog raws li qhov zaus ntawm kev siv lub valve thiab ib puag ncig ua haujlwm. Xws li kev tu cov chaw sab hauv thiab sab nraud ntawm lub valve, kuaj seb cov teeb meem tau xoob, thiab lwm yam los ntawm lub sijhawm ntev los rau lub sijhawm ntev kev pabcuam lub neej ntawm lub valve.
2. Xaiv cov khoom lag luam zoo: rau cov qauv hluav taws xob txo qis kev pheej hmoo ntawm valve tognage, nws yog ib qho tsim nyog los xaiv cov khoom lag luam zoo hauv valve. Los ntawm cov khoom xaiv, cov qauv tsim qauv rau cov txheej txheem ntau lawm, cov khoom siv hluav taws xob raug tswj hwm kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws. Kev ua haujlwm raug thiab kev teeb tsa: Ua raws cov txheej txheem ua haujlwm thiab ua haujlwm ntawm lub valve kom raug. Thaum lub sij hawm cov txheej txheem teeb tsa, them sai sai rau txoj hauj lwm teeb tsa thiab kev coj ntawm lub valve kom paub tseeb tias lub valve yuav qhib tau thiab kaw ib txwm. Nyob rau tib lub sijhawm, zam kev thov kom muaj zog ntau dhau ntawm lub valve lossis ntaus lub valve.
