Raws li cov cuab yeej tseem ceeb rau kev sau cov plua plav thiab cov khoom pov tseg, kev ua haujlwm ruaj khov ntawm cov hmoov av hlau ncaj qha cuam tshuam rau kev txuas ntxiv ntawm cov tshuab tsim khoom thiab kev ua raws li ib puag ncig. Hauv kev siv cov tswv yim, kev tsis saib xyuas qhov tseem ceeb ntawm kev tsim, kev teeb tsa, kev ua haujlwm, thiab kev saib xyuas tuaj yeem ua rau cov khoom sib sau ua ke, cov khoom siv coj los ua, xau, thiab txawm tias muaj kev nyab xeeb. Yog li ntawd, kev qhia kom meej thiab ua raws li cov kev ceev faj tseem ceeb yog qhov tseem ceeb los ua kom lub sijhawm ntev -, kev pabcuam zoo ntawm cov plua plav hlau hlau.
Ua ntej, cov yam ntxwv ntawm kev ua haujlwm yuav tsum tau txiav txim siab tag nrho thaum lub sijhawm tsim thiab xaiv. Lub ntim, cov duab, thiab lub kaum sab xis ntawm cov plua plav hopper yuav tsum phim lub cev lub cev ntawm cov khoom, nrog rau cov khoom loj me me, cov ntsiab lus noo noo, adhesion, thiab flowability. Rau cov ntaub ntawv uas muaj kev sib txuas los yog kev sib sau ua ke, lub hopper nrog lub khob hliav qab loj dua lossis ib qho khoom siv los tiv thaiv -bridging yuav tsum tau siv kom tsis txhob muaj qhov chaw tuag uas cuam tshuam cov khoom tawm. Kev xaiv cov khoom yuav tsum xav txog qhov kub, av noo, thiab corrosive media ib puag ncig. Piv txwv li, nyob rau hauv siab -kub flue gas tej yam kev mob, tshav kub-resistant steel los yog ib txheej rwb thaiv tsev yuav tsum tau siv; nyob rau hauv acidic los yog alkaline ib puag ncig, stainless hlau los yog corrosion-cov ntaub ntawv tiv taus yog qhov zoo dua los tiv thaiv kev ua haujlwm luv luv vim cov khoom siv tsis zoo corrosion. Tsis tas li ntawd, qhov loj thiab qhov chaw ntawm lub qhov hluav taws xob thiab qhov hluav taws xob yuav tsum raug sib npaug nrog cov khoom sib txuas ntawm cov khoom siv ntws thiab cov dej ntws los tiv thaiv kom tsis txhob muaj huab cua luv luv -circuiting lossis plua plav tawm.
Cov txheej txheem installation yuav tsum xyuas kom muaj kev ruaj ntseg thiab txhim khu kev qha sealing. Cov ntoo tshauv hopper txhawb nqa ncej yuav tsum tau kho rau lub hauv paus lossis cov qauv cog raws li kev tsim qauv. Welded los yog bolted kev sib txuas yuav tsum tau kuaj xyuas kom tsis txhob txav los yog tawg los ntawm kev co lossis kev hloov pauv. Cov khoom siv tau yooj yim los yog sealing gaskets yuav tsum tau nruab rau ntawm cov ntsiab lus txuas nrog cov khoom siv tshem tawm plua plav lossis cov kab ntau lawm kom nqus cov deformation los ntawm thermal expansion thiab contraction thiab tiv thaiv huab cua thiab plua plav to. Rau cov hmoov tshauv hoppers teem nyob rau hauv qhov siab los yog cantilevered, tag nrho stability thiab seismic kev ua tau zoo yuav tsum tau xyuas, thiab txij nkawm platforms thiab kev ruaj ntseg railings yuav tsum tau ntsia raws li tsim nyog los xyuas kom meej kev ruaj ntseg ntawm cov neeg ua haujlwm tu.
Thaum lub sijhawm ua haujlwm, cov khoom siv ntws thiab cov khoom siv thauj khoom yuav tsum tau saib xyuas. Kev ua haujlwm ntev ntev yuav tsum tau zam kom tsis txhob ua kom nrawm hopper phab ntsa hnav lossis kev ua haujlwm qaug zog. Rau cov ntaub ntawv uas muaj cov khoom siv tawv tawv lossis cov khoom siv abrasive heev, kev hnav khaub ncaws sab hauv ntawm phab ntsa yuav tsum tau kuaj xyuas tsis tu ncua, thiab hnav- cov hnab looj tiv thaiv yuav tsum tau ntxiv rau cov chaw tsis muaj zog lossis cov khoom siv vuam yuav tsum tau siv. Thaum lub sijhawm ua haujlwm, kev saib xyuas yuav tsum tau them rau qhov qhib thiab kaw zaus thiab ceev ntawm cov khoom siv thauj khoom kom tsis txhob muaj kev puas tsuaj rau cov khoom sib kis los ntawm kev cuam tshuam tam sim ntawd. Nyob rau tib lub sijhawm, yuav tsum tau tsim ib qho kev tshuaj ntsuam xyuas tsis tu ncua los soj ntsuam cov suab nrov txawv txav, cov cua sov hauv ib cheeb tsam, lossis cov dej ntws tawm, txheeb xyuas tam sim thiab daws qhov laj thawj.
Kev tu thiab tu yog qhov tseem ceeb sib npaug. Plua plav yooj yim accumulates hauv cov tshauv hopper; Yog tias tsis tu tsis tu ncua, nws tsis tsuas yog txo qhov ntim tau zoo xwb tab sis kuj tseem tuaj yeem ua rau lub qhov cub tawg vim deliquescence los yog tshuaj lom neeg cov tshuaj tiv thaiv, ua rau muaj kev tawm tsam thiab ua rau muaj hluav taws kub. Kev ntxuav yuav tsum tsuas yog ua tom qab lub tshuab kaw lawm, lub hwj chim txiav tawm, thiab tag nrho cov seem seem lossis cov pa phem raug tshem tawm. Cov neeg ua haujlwm yuav tsum hnav cov plua plav thiab cov cuab yeej tiv thaiv thiab ua raws li cov cai tswj kev ua haujlwm hauv chaw kaw. Rau cov hmoov tshauv hoppers nruab nrog qib saib xyuas, ntsuas kub, lossis kev vibration sensors, qhov tseeb sensor yuav tsum tau ntsuas tsis tu ncua kom ntseeg tau cov teeb liab txhim khu kev qha thiab muab lub hauv paus rau kev tswj tsis siv neeg thiab ceeb toom ntxov.
Hauv cov ntsiab lus, kev siv thiab kev saib xyuas ntawm cov hlau tshauv hoppers muaj ntau yam, nrog rau kev tsim qauv, kev ruaj ntseg installation, kev saib xyuas kev ua haujlwm, thiab kev saib xyuas tsis tu ncua; kev ceev faj rau txhua qhov yog sib cuam tshuam. Tsuas yog los ntawm kev siv cov txheej txheem kev qhia tshwj xeeb thiab kev tswj xyuas kev nyab xeeb tuaj yeem ua kom peb cov khoom siv tau zoo thaum ua tiav ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov khoom siv thiab ua raws li kev tiv thaiv ib puag ncig.
