Raws li ib qho tseem ceeb ntawm kev lag luam li qub rau kev kho dej hauv cov kav dej,npauj npaim li qubyuav raug kev txom nyem sib txawv ntawm kev hnav vim nquag siv nyob rau hauv lub sij hawm ntev thiab hnyav ib puag ncig. Yog li ntawd, kev tu thiab kho tsis tu ncua kuj tseem tsim nyog. Tsuas yog hloov cov khoom tsim nyog kom tsis txhob siv cov khoom kaw lossis kev nyab xeeb los ntawm lub valve tsis ua haujlwm, uas tuaj yeem txuas ntxiv siv lub valve thiab txuag nqi.
Dab tsi yog kev saib xyuas ntawm npauj npaim valve?Npauj npaim valve kho kho tej zaum yuav txawv nyob ntawm seb hom kev puas tsuaj los yog tsis ua hauj lwm. Nws tuaj yeem muab faib ua kev saib xyuas, kho dav dav thiab kho hnyav.
- Kev saib xyuas yog hais txog kev saib xyuas txhua hnub, thiab tsis tas yuav tsum tau disassemble tus npauj npaim valve lossis hloov qhov chaw. Piv txwv li, thaum tsis siv lub npauj npaim valve, cov dej ntim yuav tsum tau ntws, lubrication yuav tsum tau ua, thiab lub npauj npaim valve yuav tsum tau kuaj xyuas tsis tu ncua rau cov xau.
- Kev saib xyuas dav dav hais txog valve qia straightening, txuas bolt zawm, thiab lwm yam.
- Kev saib xyuas hnyav yuav tsum tau hloov cov phaj valve, lub rooj zaum valve thiab lwm yam khoom loj.
Dab tsi yog qhov tseem ceeb ntawm npauj npaim valve?
Qhov tseem ceeb ntawm npauj npaim li qub suav nrog:
Lub cev.
Disc.
Qe.
Rooj.
Tus actuator.
Yog li, Yuav ua li cas kho npauj npaim valve?
1. Thawj kauj ruam ntawm kev saib xyuas yog los txiav txim qhov teeb meem txhaum cai.
Yuav ua li cas los daws qhov npauj npaim valve?Ua tib zoo tshuaj xyuas lub valve thiab cov khoom nyob ib puag ncig. Tsuas yog los ntawm kev txheeb xyuas qhov tseeb ntawm qhov teeb meem koj tuaj yeem kho nws kom tsim nyog. Piv txwv li, tej zaum yuav muaj qhov xau los ntawm kev sib txuas xoob. Tsis tas yuav tshem lub valve thiab hloov lub rooj zaum valve, ib yam li tsis tas yuav tsum tau phais yog tias koj mob khaub thuas.
Leakage - Loos bolts, valve rooj thiab cov ntsaws ruaj ruaj tej zaum yuav muaj hnub nyoog, ua rau to thiab cuam tshuam lub valve sealing peev xwm.
Hnav - Tsis pub dhau lub valve, lub disc, qia thiab cov ntsaws ruaj ruaj yuav raug hnav thiab tsim kua muag vim kev ua haujlwm ntawm tus qauv, ua rau txo qis kev ua haujlwm thiab xau.
Corrosion - Sij hawm dhau mus, txuas ntxiv mus rau qhov chaw corrosive tuaj yeem ua rau cov khoom puas tsuaj
Stuck valve qia - Vim qhov nkag ntawm cov khoom txawv teb chaws, lub qia valve yuav daig, ua rau lub valve tsis ua haujlwm zoo.
2. Yog hais tias lub valve tiag tiag yuav tsum tau disassembled, ces peb mus rau theem ob.
Ua ntej disassembly, thov kaw lub valve sab sauv kom tsis txhob muaj cov kua dej ntws tawm thiab ua kom lub cev muaj zog kom muaj kev nyab xeeb. Tshem tawm tag nrho cov kev sib txuas rau lub valve thiab txiav lub tshuab hluav taws xob lossis pneumatic actuator (yog tias muaj). Siv cov cuab yeej tsim nyog los loosen thiab tshem tawm bolts lossis fasteners tuav li qub thiab cov kav dej hauv qhov chaw.
Kev ceeb toom sov: Ua tib zoo saib rau kev teeb tsa thiab kev taw qhia ntawm cov khoom siv rau kev sib dhos.
3. Tshawb xyuas kev puas tsuaj:
Tom qab tshem tawm lub valve, tshuaj xyuas cov tsos ntawm txhua yam khoom kom pom kev puas tsuaj, hnav, lossis corrosion. Tshawb xyuas lub disc, qia, lub rooj zaum, cov ntsaws ruaj ruaj thiab lwm yam khoom siv rau kev tawg, corrosion lossis deformation.
Cov txheej txheem ntawm disassembling npauj npaim valve yog qhia hauv video hauv qab no.
4. Kho thiab hloov cov khoom faulty
Yog tias muaj impurities daig ntawm lub phaj valve thiab lub rooj zaum valve, ua ntej tshem tawm cov impurities thiab saib seb lub rooj zaum valve puas deformed vim qhov no.
Yog tias lub valve qia yog deformed, nws tuaj yeem raug tshem tawm thiab ncaj.
Yog tias ib qho twg raug pom tias puas los yog hnav dhau ntawm kev kho, nws yuav tsum tau hloov nrog qhov tsim nyog hloov. Xyuas kom tseeb tias qhov hloov pauv yog tib qhov tshwj xeeb raws li qhov qub. Cov khoom siv uas yuav tsum tau hloov pauv muaj xws li cov ntsaws ruaj ruaj, stems, thiab O-rings.
5. Rov ua kom lub valve
Reassemble tus npauj npaim valve nyob rau hauv qhov kev txiav txim rov qab ntawm disassembly. Ntxuav thiab lubricate qhov chaw raws li xav tau los xyuas kom meej kev ua haujlwm du thiab sealing zoo. Tighten bolts los yog fasteners, ceev faj tsis txhob overtighten kom tsis txhob puas valve Cheebtsam los yog nto.
6. Kev xeem
Tom qab lub valve tau reassembled, functionality yuav tsum tau kuaj ua ntej muab tso rau hauv kev pab cuam. Ua ntej, ua ib qho kev ntsuam xyuas siab ib leeg los soj ntsuam kev ua haujlwm ntawm lub valve thiab xyuas seb puas los yog qhov txawv txav. Txheeb xyuas lub valve qhib thiab kaw.
7. Kev teeb tsa
Cov txheej txheem reinstallation kom raug yog qhov tseem ceeb rau kev ua tiav kev ua haujlwm zoo ntawm lub valve, txuas lub neej ntawm lub valve, thiab ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
