Atlas Copco ntsia hlau cua compressors ua lub luag haujlwm tseem ceeb hauv kev ua kom ruaj khov huab cua hauv kev tsim khoom.Ua tsis tiav pibyog qhov feem ntau ntawm - qhov chaw txhaum thiab cuam tshuam ncaj qha rau kev tsim khoom. Kab lus no muab tag nrho - txheej txheem kev daws teeb meem los ntawm kev yooj yim mus rau qhov nyuaj, los ntawm kev soj ntsuam ceev mus rau hauv - kev saib xyuas qhov tob, npog plaub qhov loj: hluav taws xob, kev tswj, tshuab, thiab kev tiv thaiv, pab koj sai nrhiav qhov txhaum, rov pib ua haujlwm, thiab txo qis lub sijhawm poob.
Fault Overview: Thawj Tus Txiav Txim 3 Yam Phenomena
Tom qab nias lub pob pib, cov khoom siv feem ntau nthuav tawm 3 hom xeev, sib xws rau cov lus qhia txhaum cai sib txawv:
Tsis teb kiag li: Tsis muaj vaj huam sib luag zaub, tsis muaj qhov taw qhia teeb, tsis muaj suab → Ua ntej kuaj xyuas lubfais fab mov thiab hluav taws xob nres Circuit Court
Buzzing / kev sib koom ua suab tab sis tsis muaj kev sib hloov→ Ua ntej kuaj xyuasvoltage, theem poob, contactor, thiab lub cev muaj zog load
Tripping/alarming tam sim ntawd tom qab pib→ Ua ntej kuaj xyuasoverload, lub ntsiab chav nyob qaug dab peg, thiab kev tiv thaiv ntaus ntawv qhib
Ua raws li txoj cai ntawmlos ntawm sab nraud mus rau sab hauv, los ntawm hluav taws xob mus rau mechanical, los ntawm yooj yim mus rau complexrau kev daws teeb meem kom tsis txhob dig muag disassembly.
Kauj Ruam 1: Kev Siv Hluav Taws Xob & Hluav Taws Xob Hluav Taws Xob (80% ntawm Kev Ua Phem Los Ntawm No)
1. External Power Supply Check
- Tshawb xyuas seb lub ntsiab hloov pauv, qhov hluav taws xob hluav taws xob, thiab fuse raug kaw thiab puas lawm
- Ntsuas peb -theem voltage nrog multimeter: ib txwm ± 10% ntawm tus nqi ntsuas; kev pib ua tsis tau yog tias qis dua 90%
- Teeb meemtheem poob, theem ua ntu zus yuam kev, thiab nruab nrab xaim rov qab txuas; Cov qauv Atlas Copco yuav ncaj qha kaw lub tsev vim muaj kev tiv thaiv theem
- Xyuas seb cov kab txuas thiab cov terminals puas xoob, ablated, lossis oxidized
2. Tswj Kev Siv Hluav Taws Xob & Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
- Xyuas seb cov vaj huam sib luag xws li Elektronikon puas yog; Yog tias tsis yog, thawj zaug xyuas cov tswj transformer thiab fuse
- Paub meej tias covkhawm nres xwm ceev, qhov rooj hloov, thiab kev nyab xeeb npog hloovtau rov pib dua
- Xyuas seb cov kab tswj tau xoob, luv -circuited, los yog tawg
3. Contactors & Relays
- Mloog rau contactor kev koom tes thaum pib; Yog tias tsis koom nrog, tshawb xyuas lub kauj, pab pawg sib cuag, thiab pib khawm
- Ablated los yog daig hu yuav ua rau tsis ua hauj lwm los hloov / tawm ib txwm thiab yuav tsum tau polished los yog hloov
- Tom qab lub thermal overload relay mus ncig ua si, nws yuav tsum yogtxias thiab rov pib duaua ntej rov pib dua
Kauj Ruam 2: Tswj System & Kev Tiv Thaiv Logic (Prioritize Vaj Huam Sib Luag Alarms)
Atlas Copco cua compressors tau nruab nrog kev tiv thaiv ua tiav, thiab kev pib ua haujlwm yuav tsum ua kom tau raws li kev khiav haujlwm:
Clear keeb kwm tswb: Lub tsev yuav kaw yog tias lub tswb nrov xws li kub siab, siab siab, qis roj theem, lub cev muaj zog tshaj, thiab lim clogging tsis rov pib dua
Tshawb xyuas pib- nres tej yam kev mob: Lub kaw lus siab dhau lawm, tsis raug chaw taws teeb / hom hauv zos, thiab tsis muaj sijhawm kaw
Tswj tsis tau: Txheeb xyuas seb qhov ntsuas tau raug hloov kho tsis raug thiab yog tias kev sib txuas lus cuam tshuam
Sensor xwm txheej: Kev ua txhaum ntawm qhov kub, siab, thiab roj qib sensors yuav thaiv lub teeb liab pib
Kev tuav ceev: Ua ntej uarov pib duantawm lub vaj huam sib luag; yog tias nws tseem tsis tau pib, xyuas qhov kho vajtse.
Kauj Ruam 3: Mechanical & Main Unit System (Forbidden to Force Startup)
1. Cheebtsam ntawm qhov qaug dab peg / nyuaj Cranking (Feem ntau txaus ntshai)
Txiav tawm lub hwj chim mov thiab manually crank lub coupling los yog flywheel
Yog tias nws tsis tuaj yeem cranked, tau daig, lossis hnov qhov hnyav → Main unit qaug dab peg: tsis muaj roj, carbon deposition, bearing puas tsuaj, los yog cov khoom txawv teb chaws nkag.
Txwv tsis pub rov sim inching, uas yuav hlawv lub cev muaj zog thiab puas lub ntsiab chav tsev
2. Lub cev muaj zog
Ntsuas lub cev muaj zog rwb thaiv tsev thiab peb -theem tsis kam los txiav txim winding luv Circuit Court, qhib Circuit Court, thiab grounding
Lub cev muaj zog kev puas tsuaj thiab stator-rotor rubbing yuav ua rau muaj kev tiv thaiv ntau dhau
3. Kev Siv Hluav Taws Xob
Belt- cov qauv tsav: siv txoj hlua tawg, nruj heev, lossis ntog
Direct-cov qauv sib txuas: cov coupling puas, misalignment, lossis tawg elastomer
Kauj Ruam 4: Roj Circuit Court & Auxiliary System (Easy Overlooked)
Lorem ipsum dolor sit amet consectetur adipisicing elit.
Cov roj lubricating tsawg dhau thiab cov roj tsis zoo heev ua rau muaj kev tiv thaiv vim tsis txaus lubrication ntawm lub ntsiab chav tsev.
Kev pib nyuaj nyob rau hauv lub siab yog tias cov roj - roj tank siab tsis txo qis
Stuck kub tswj valve thiab roj txiav-off valve cuam tshuam rau kev pib ua haujlwm
5-Txoj kev daws teeb meem ceev ceev (On-Site First Choice)
Yog tias nws tseem ua tsis tau zoo, nkag mus rau hauv - kev saib xyuas qhov tob.

Ua haujlwm zoo hauv kev tiv thaiv plua plav thiab noo noo kom ntev kev pab cuam lub neej ntawm cov khoom siv hluav taws xob
Xaus
Rau Atlas Copco ntsia hlau cua compressors uas tsis pib, qhov ua tau zoo tshaj plaws yoghluav taws xob thawj, mechanical thib ob; tiv thaiv thawj, mechanical thib ob. Feem ntau cov teeb meem tuaj yeem daws tau sai los ntawm kev kuaj xyuas lub zog, nres thaum muaj xwm ceev, tswb, thiab cranking. Nyob rau hauv cov ntaub ntawv ntawm lub hauv paus qaug dab peg los yog lub cev muaj zog rwb thaiv tsev faults, nws raug nquahu kom hu rau cov kws tshaj lij tom qab - kev muag khoom kom tsis txhob nthuav kev puas tsuaj.
