Nruas flakers yog cov neeg ua haujlwm hauv kev lag luam uas ua kom cov ntaub ntawv zoo li caustic soda (NaOH), stearic acid, lossis phenol. Tab sis zoo li txhua lub tshuab muaj precision, lawv xav tau kev saib xyuas zoo ib yam los ua kom ntseeg tau. Kev saib xyuas tsis zoo tuaj yeem ua rau tsis sib xws, lub nruas corrosion, scraper hnav, lossis txawm tias tsis tau npaj kaw - raug nqi ntau txhiab hauv kev tsim khoom ploj.
Ntawm Wuxi Chengzhixin, nrog ntau tshaj 200 lub nruas flakers tau teeb tsa thoob ntiaj teb txij li xyoo 2012, peb tau pom ua ntej yuav ua li cas cov txheej txheem tu txheej txheem tiv thaiv 80% ntawm kev ua tsis tiav. Hauv phau ntawv qhia no, peb yuav qhia koj txog qhov ua tau zoo, kauj ruam - los ntawm - kauj ruam kev npaj ua haujlwm - npog txhua hnub, txhua lub limtiam, txhua hli, thiab txhua xyoo.
Yog vim li cas Drum Flaker Maintenance tseem ceeb heev
* Tiv thaiv corrosion nyob rau hauv siab -kub, corrosive ib puag ncig (xws li, molten NaOH ntawm 180 degree)
* Ua kom zoo ib yam flake thickness thiab zoo
* Txo kev siv hluav taws xob los ntawm kev tswj xyuas thermal efficiency
* Zam tsis txhob muaj kev puas tsuaj loj xws li lub nruas xau los yog kev qaug dab peg
Cov Haujlwm Saib Xyuas Txhua Hnub (5–10 feeb)
* Tshawb xyuas cov dej xau:Tshawb xyuas lub nruas ntsaws ruaj ruaj, kev sib txuas ua kom txias, thiab cov kab pub rau cov paib ntawm NaOH lossis fatty acid to.
* Saib xyuas qhov kub thiab txias:Kev hloov tam sim ntawd yuav qhia tau tias muaj teeb meem txhaws lossis twj tso kua mis.
* Mloog rau lub suab txawv txav:Kev sib tsoo lossis khob suab tuaj yeem ua rau muaj kev cuam tshuam ntawm kev coj tus kheej lossis kev sib tsoo tsis zoo.
* Ntxuav cov chaw sab nraud:Tshem tawm cov plua plav, flakes, los yog tshuaj lom neeg kom tiv thaiv kev tsim thiab xeb.
Cov hauj lwm tu txhua lub lim tiam
* Tshawb xyuas scraper hniav mob: Look for chipping, warping, or excessive wear. Replace if edge thickness is reduced by >30%.
* Lubricate bearings & tsav Cheebtsam:Siv siab -tej roj ntsuas rau koj qhov chaw ua haujlwm.
* Txheeb xyuas qhov sib txawv:Xyuas kom lub scraper nyob rau hauv parallel mus rau lub nruas nto (nruab nrab kam rau ua: ± 0.1 hli).
Kev soj ntsuam txhua hli
* Tshawb xyuas lub nruas nto:Siv lub teeb nyem thiab daim iav los xyuas qhov pitting, tawg, lossis yaig-tshwj xeeb nyob ze ntawm thaj chaw pub.
* Kuaj nres thaum muaj xwm ceev & kev nyab xeeb cuam tshuam:Qhov tseem ceeb rau kev ua raws li CE / ATEX.
* Tshawb xyuas qib vibration: Use a handheld vibrometer; values >4.5 mm / s tej zaum yuav qhia tau hais tias tsis txaus los yog bearing tsis ua hauj lwm.
Kev Saib Xyuas Txhua Xyoo & Hloov Kho
Ib xyoos ib zaug (lossis txhua 4,000–6,000 teev ua haujlwm), teem caij kuaj xyuas tag nrho:
* Disassemble thiab tshuaj xyuas lub ntsiab bearings, ntsaws ruaj ruaj, thiab ncej
* Siab- sim lub nruas rau micro- tawm (tshwj xeeb yog tias tuav cov dej qab zib caustic)
* Re-calibrate kub sensors thiab PLC tswj
* Hloov cov hniav txhuam hniav, gaskets, thiab coolant hoses
* Ua tsis yog -kev kuaj kev puas tsuaj (NDT) ntawm lub nruas welds yog tias xav tau los ntawm cov cai hauv zos
Sab saum toj 3 Nruas Flaker teeb meem-thiab Yuav Kho Li Cas
1. Tsis sib xws los yog Chunky Flakes
Ua rau:Scraper misalignment, tsis sib haum xeeb pub kub, los yog nruas nto paug.
Kev daws:Realign scraper, stabilize yaj kub, huv si nruas nto nrog pom zoo hnyav.
2. Ceev nrooj Corrosion
Ua rau:Siv cov khoom siv tsis raug (piv txwv li, SS304 rau NaOH kub) lossis cov dej txias uas muaj cov ntsiab lus chloride siab.
Kev daws:Txhim kho rau duplex stainless hlau lossis Alloy 20; siv cov dej txias deionized.
3. Kev vibration ntau dhau
Ua rau:Tsis sib npaug nruas, hnav bearings, los yog xoob mounting bolts.
Kev daws:Rebalance nruas, hloov bearings, torque - xyuas lub hauv paus bolts.
Cov Lus Qhia Txog Kev Kho Mob los ntawm CHENGZHIXIN Engineers
"Ib txwm khaws cov khoom seem scraper hniav ntawm -site- lub sijhawm tos rau cov nqi ntau dua li cov khoom muag."
"Rau cov ntawv thov fatty acid, khiav 'lub voj voog tu' nrog cov roj kub txhua lub lim tiam los tiv thaiv kev tsim cov polymerization."
"Lu npe tag nrho cov haujlwm saib xyuas digitally-cov kev nyiam nthuav qhia cov teeb meem zais ua ntej lawv nce ntxiv."

FAQ Tshooj
Q1: Kuv yuav tsum tau hloov cov hniav scraper ntau npaum li cas?
A: Feem ntau txhua 3-12 lub hlis, nyob ntawm cov khoom siv abrasiveness. Caustic soda hniav siv sijhawm ntev dua li cov uas siv rau cov kua qaub puv.
Q2: Kuv puas tuaj yeem siv cov kais dej ua kom txias?
A: Tsis yog. Ib txwm siv cov dej softened los yog deionized los tiv thaiv cov nplai buildup hauv lub nruas, uas txo cov cua sov hloov thiab ua rau overheating.
Q3: Koj puas muab kev cob qhia tu?
A: Yog! Peb muab kev cob qhia online thiab ntawm -qhov chaw cob qhia rau cov neeg ua haujlwm thiab pab pawg saib xyuas- muaj ua lus Askiv, Mev, thiab Arabic.
