Hnyav -Lub Luag Haujlwm Ob Chav Suction Centrifugal Pump Rau Kev Kho Dej Dej

I. Ua ntej Kev Kho Mob: Kev Nyab Xeeb thiab Kev Npaj yog lub hauv paus
Ua kom tiav lub zog thiab dej disconnection:
Tua lub hwj chim tseem ceeb ntawm lub twj tso kua mis thiab kaw nws, thiab dai ib daim paib hais tias "Txhim kho hauv kev nce qib - Tsis txhob kaw qhov hloov"; Kaw lub qhov dej nkag thiab qhov hluav taws xob, tso cov kua uas seem hauv lub twj tso kua mis lub cev kom tiv thaiv kom tsis txhob muaj hluav taws xob los yog hluav taws xob poob.
Npaj cov cuab yeej thiab cov khoom seem:
Npaj cov wrenches, screwdrivers, seals (xws li O-rings, mechanical seals), lubricants, thiab lwm yam.
Sau lub xeev qub:
Siv cov duab los yog sau cov qauv kev sib txuas ntawm lub twj tso kua mis, txoj hauj lwm ntawm cov khoom (xws li cov kev taw qhia ntawm lub impeller, cov yeeb nkab interface), tshwj xeeb tshaj yog rau cov qauv tsis paub meej kom tsis txhob muaj kev sib dhos tsis raug.
II. Thaum Lub Sijhawm Saib Xyuas: Disassembly thiab Kev Tshuaj Xyuas yog lub hauv paus
Disassembly ua raws li lub hauv paus ntsiab lus ntawm "los ntawm sab nraud mus rau sab hauv":
Ua ntej, tshem tawm cov kab kev sib txuas ntawm lub cev thiab cov kav dej hauv dej thiab qhov hluav taws xob, tom qab ntawd tshem tawm lub twj tso kua mis kawg, lub impeller, bearings thiab lwm yam khoom siv sab hauv kom tsis txhob ua rau cov xov los yog sealing qhov chaw vim muaj kev sib tsoo hnyav.
Tsom ntsoov rau kev tshuaj xyuas cov khoom tsis zoo:
Sealing system:
Xyuas seb lub nplhaib txav thiab nyob ruaj ruaj ntawm lub tshuab foob puas hnav lossis tawg, thiab seb lub nplhaib O- puas muaj hnub nyoog lossis deformed. Qhov no yog qhov tseem ceeb rau kev tiv thaiv cov dej tawm.
Rotating Cheebtsam:
Tig lub impeller los ntawm txhais tes kom hnov ​​​​yog tias muaj kev cuam tshuam lossis suab nrov txawv txav. Xyuas seb lub impeller puas corroded, puas los yog clearance ntawm impeller flange loj heev (ntau tshaj clearance yuav txo lub twj tso kua mis efficiency).
Bearings thiab shafts:
Xyuas seb cov bearings puas xeb los yog cov khoom hnav. Xyuas seb lub ncej yog khoov los yog muaj cov cim hnav. Yog hais tias tus ncej runout tshaj tus qauv, nws yuav tsum tau kho los yog hloov nyob rau hauv lub sij hawm.
Ntxuav cov khoom kom tsis txhob impurities:
Tom qab disassembling lub Cheebtsam, ntxuav lawv nrog kerosene los yog tshwj xeeb tu cov neeg ua hauj, tshwj xeeb tshaj yog cov bearing vaj tse, sealing chamber thiab lwm yam. Tiv thaiv cov seem impurities los ntawm ua rau hnav ntawm cov khoom tshiab.
III. Tom qab Kev Kho: Kev sib dhos thiab kev sim yog qhov tseem ceeb
Reassemble raws li thawj cov ntaub ntawv nyob rau hauv reverse order:
Xyuas kom meej tias tag nrho cov khoom xws li lub impeller thiab cov ntsaws ruaj ruaj raug ntsia kom raug, thiab cov bolts tau nruj nruj (kom tiv thaiv lub twj tso kua mis lub cev los ntawm deforming vim muaj kev ntxhov siab ntau hauv zos) raws li cov ntaub ntawv thaum lub sij hawm disassembly.
Ntxiv cov roj lubricating uas tsim nyog:
Ntxiv qhov tsim nyog ntawm cov roj lubricating (xws li 32 lossis 46 hom roj twj tso kua mis) rau cov kabmob vaj tse. Cov roj qib yuav tsum nyob ntawm 1/2 - 2/3 ntawm cov roj ntsuas. Cov roj ntau dhau los yog tsis txaus yuav cuam tshuam rau lub tshav kub dissipation thiab lubrication ntawm bearings.
Tsis muaj- load thiab load tests :
Tsis yog-Load test: Tom qab lub tshuab hluav taws xob, cia lub twj tso kua mis ua haujlwm rau 1-2 feeb. Xyuas seb qhov kev hloov ntawm lub cev muaj zog yog qhov tseeb, yog tias muaj lub suab txawv txav, thiab yog tias qhov kev vibration zoo li qub.
Load test: Qhib lub qhov dej nkag thiab qhov hluav taws xob. Saib xyuas seb lub twj tso kua mis lub siab thiab cov dej ntws tau raws li cov qauv. Nyob rau tib lub sijhawm, xyuas seb puas muaj qhov xau ntawm qhov chaw sib khi. Khiav rau 30 feeb thiab kov lub rooj zaum. Qhov kub yuav tsum tsis pub tshaj 70℃kom nws zoo li qub.

Hnyav-Lub luag haujlwm Ob Chav Suction Centrifugal Twj Tso Kua Dej Rau Kev Kho Dej Dej Raws li qhov zoo thiab qhov tsis zoo, qhov zoo yog qhov txaus ntshai, lub taub hau ruaj khov, me me axial quab yuam, thiab kev saib xyuas yooj yim. Qhov tsis zoo yuav yog qhov loj me, hnyav hnyav, tejzaum nws ua haujlwm qis dua piv rau ib qho - nqus twj, thiab qhov yuav tsum tau muaj rau kev txhim kho raug. Peb yuav tsum sib npaug qhov zoo thiab qhov tsis zoo no kom cov neeg siv nkag siab txog cov xwm txheej siv tau.
Nyob rau hauv cov ntaub ntawv ntawm daim ntawv thov teb, lawv yuav tsum muaj xws li dej mov thiab dej, ua liaj ua teb irrigation, fais fab nroj tsuag, tshuaj nroj tsuag, dej phwj kho mob, thiab lwm yam. Nyob rau hauv cov teb uas yuav tsum tau loj txaus tus nqi, ob - suction twj tso kua mis yog tsim nyog. Tej zaum qee qhov piv txwv tshwj xeeb tuaj yeem muab tau zoo ib yam, xws li kev siv dej hauv nroog thiab cov twj siv hluav taws xob hauv cov chaw tsim hluav taws xob.

Nyob rau hauv nqe lus ntawm kev txiav txim siab xaiv, nws yog ib qho tsim nyog yuav tsum nco ntsoov cov neeg siv kom coj mus rau hauv tus account yam xws li tus nqi ntws, lub taub hau, cov yam ntxwv nruab nrab, kev teeb tsa thiab kev ua haujlwm zoo. Hauv particular, qhov kub thiab corrosiveness ntawm qhov nruab nrab, nrog rau qhov loj ntawm qhov chaw nruab, tag nrho cov no yuav cuam tshuam rau kev xaiv. Nws kuj tseem yuav tsum tau hais txog cov qauv thiab cov ntawv pov thawj, xws li ISO thiab API, kom ntseeg tau tias lub twj tso kua mis zoo.
Nws yog ib qho tsim nyog los xyuas seb puas muaj cov khoom tshem tawm, xws li kev faib tawm ntawm ob - cov twj nqus dej, seb puas muaj ntau hom, xws li kab rov tav thiab ntsug? Los yog muaj lwm yam kev hloov pauv? Tsis tas li ntawd, nws yog ib qho tsim nyog los sib piv qhov sib txawv ntawm ob - cov twj nqus dej thiab ib qho - cov twj nqus dej los pab cov neeg siv nkag siab zoo dua. Tsis tas li ntawd, xyuam xim rau kev siv cov lus yooj yim thiab nkag siab, zam ntau cov lus tshaj lij, lossis piav qhia cov ntsiab lus thaum tsim nyog.
Cov neeg siv yuav yog engineers, procurement neeg ua hauj lwm los yog cov tub ntxhais kawm, thiab lawv xav tau cov ncauj lus kom ntxaws tab sis meej. Yog hais tias nws yog ib tug engineer, lawv yuav muaj kev txhawj xeeb ntau ntxiv txog cov kev tsis sib xws thiab daim ntawv thov scenarios; yog tias nws yog ib tug menyuam kawm ntawv, lawv yuav xav tau cov hauv paus ntsiab lus thiab cov qauv. Yog li ntawd, cov ntsiab lus yuav tsum ua tiav, suav nrog ntau theem ntawm cov kev xav tau. Thaum kawg, xyuas kom meej cov qauv, nrog cov ntsiab lus kom meej meej, kom yooj yim rau cov neeg siv nyeem.
