Kauj Ruam 1: Tsim cov cai ua ntej thiab tsim cov ntaub ntawv saib xyuas
1. Txhim kho cov txheej txheem kev khiav hauj lwm thiab kev saib xyuas: tsim kom meej cov txheej txheem kev khiav hauj lwm txhua hnub thiab kev saib xyuas cov neeg ua haujlwm kom muaj lub hauv paus ruaj khov rau kev ua haujlwm tu.
2. Tsim cov ntaub ntawv kev noj qab haus huv ntawm cov cuab yeej: Tsim cov ntaub ntawv kho tus kheej rau txhua yam khoom siv, piav qhia txog "lub sijhawm ua haujlwm," "cov xwm txheej tsis zoo," "cov haujlwm tu," thiab "hloov qhov chaw" rau txhua qhov piv txwv. Qhov no tsis yog tsuas yog muab cov ntaub ntawv meej meej ntawm kev saib xyuas keeb kwm tab sis kuj tseem ua cov ntaub ntawv tseem ceeb rau "kev saib xyuas kev tiv thaiv," ua kom muaj tseeb kev kwv yees ntawm cov voj voog hloov pauv rau kev hnav- cov khoom siv.
3. Ua kom muaj kev lav phib xaub rau cov kws tshaj lij: Qhia meej meej txog lub luag haujlwm ntawm cov neeg ua haujlwm, cov kws kho mob, thiab cov thawj coj hauv pab pawg txhawm rau tsim kom muaj kev tswj hwm qib uas txhua lub luag haujlwm ua tiav nws cov haujlwm tshwj xeeb, kom ntseeg tau tias kev saib xyuas cov haujlwm tau zoo.
Kauj Ruam 2: Laum txheej los ntawm txheej los ua peb - qib kev tu
1. Qib theem: Kev tshuaj xyuas thiab tu txhua hnub (pom zoo: Ua ntej thiab tom qab ua haujlwm txhua hnub)
Lub hauv paus ntsiab lus tseem ceeb: Ua kom muaj kev nyab xeeb ntawm cov hluav taws xob ib puag ncig los ntawm cov txheej txheem "saib, mloog, thiab tshawb xyuas" nrawm nrawm.
Cov txheej txheem tseem ceeb:
Kev saib xyuas ib puag ncig: xyuas kom qhov kub thiab txias hauv lub txee tswj hluav taws xob tsawg dua lossis sib npaug li 40℃thiab tswj kev tiv thaiv plua plav. Mloog rau cov suab nrov txawv txawv los ntawm cov kiv cua thiab xyuas seb cov cua ntws zoo li cas los txiav txim siab seb qhov cua sov puas zoo.
Kev Ntsuam Xyuas Kev Pom Zoo: Txheeb xyuas tag nrho cov teeb pom kev zoo thiab cov tshuaj tiv thaiv rau kev ceeb toom ua txhaum. Sniff rau cov ntxhiab tsw txawv txawv thiab tshuaj xyuas cov xov hlau rau kev sib txuas xoob, kev puas tsuaj, lossis cov cim ntawm kev kub hnyiab.
Kev tu thiab tu: Tom qab txiav lub hwj chim, siv lub tshuab nqus tsev vacuum los yog mos- txhuam txhuam kom tshem tawm cov plua plav tawm ntawm sab hauv thiab sab nrauv ntawm lub txee tswj hluav taws xob. Tsis txhob siv daim ntaub ntub dej lossis siab - rab phom cua.
2. Qib Tub Ntxhais: Hauv -Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tiv Thaiv Qhov tob (pom zoo: txhua lub limtiam / hli / Peb Hlis)
Lub hauv paus ntsiab lus tseem ceeb: Kev pab them nqi, kev tshuaj xyuas zoo, thiab kev tiv thaiv cov teeb meem tshwm sim.
Cov txheej txheem tseem ceeb:
Kev Siv Hluav Taws Xob thiab Hluav Taws Xob: Tshawb xyuas seb qhov hluav taws xob hauv lub hauv paus thiab kev tswj xyuas puas ruaj khov, thiab tshuaj xyuas cov xwm txheej ntawm cov khoom siv tiv thaiv xws li fuses thiab cov hluav taws xob hluav taws xob.
Kev nyab xeeb thiab hauv av: sim cov khawm nres thaum muaj xwm ceev thiab cov khoom siv thaiv kev nyab xeeb. Lub sijhawm tshuaj xyuas cov khoom siv hauv av; Cov qauv yuav tsum muaj kev tiv thaiv av tsawg dua lossis sib npaug rau 4Ω.
Cov Cheebtsam tseem ceeb: Txheeb xyuas qhov xwm txheej ntawm lub ntsiab PLC lub I / O qhov taw qhia teeb thiab kev sib txuas lus sib txuas. Siv lub ntsuas kub infrared los ntsuas cov khoom tseem ceeb xws li cov contactors thiab qhov sib txawv zaus tsav (VFDs). Tshawb xyuas tag nrho cov sensors thiab ntsuas ntsuas ntsuas kub kom haum rau qhov ntsuas kub tiag tiag.
Teem sijhawm hloov cov khoom siv: Rau "hnav- thiab- rhuav tshem" nrog lub neej luv luv- xws li relays, cua txias kiv cua, thiab cua sov coils- hloov pauv lawv ua ntej kawg ntawm lawv lub neej kev pabcuam raws li cov sijhawm ua haujlwm thiab cov chaw tsim khoom pom zoo kom tiv thaiv lub sijhawm poob qis.
3. Qib kws tshaj lij: Kev daws teeb meem thiab kev kuaj mob (thaum muaj qhov tsis txaus ntseeg tshwm sim)
Lub hauv paus ntsiab lus: Ua raws li kev daws teeb meem uas yog qhov tseem ceeb rau sab nraud ntawm cov khoom siv sab hauv thiab cov khoom siv hluav taws xob ntau dhau. Nyob rau tib lub sijhawm, kos rau lub tswv yim siab tshaj ntawm "qhov xwm txheej-raws li kev saib xyuas" los siv cov cuab yeej tshaj lij los ntsuas cov cuab yeej siv kev noj qab haus huv, es tsis yog cia siab rau kev tu lub voj voog nkaus xwb, yog li txhim kho kev txij nkawm thiab raug.
Kev xav Framework:
Mloog cov suab: Tshawb xyuas cov suab nrov txawv txav.
Saib cov cim qhia: Txheeb xyuas qhov taw qhia lub teeb xim thiab nrhiav cov cim hlawv.
Swb rau cov ntxhiab tsw: Tshawb xyuas qhov tsis hnov tsw ntawm hluav taws kub rwb thaiv tsev.
Cov cuab yeej siv: Multimeter, clamp meter, infrared thermometer, oscilloscope.
Cov Txheej Txheem Tshwj Xeeb: txo qis ntawm qhov dhau los ntawm kev xav txog kev xav; ua cov kev ntsuam xyuas hloov ntawm cov khoom xav tau lossis cais cov ntu ntawm Circuit Court los txheeb xyuas qhov teeb meem.
Kev daws teeb meem tseem ceeb: Kev daws teeb meem hauv qab no: 'Power Supply' ➜ 'External Wiring' ➜ 'Motor Load' ➜ 'Control Logic'.
Kev ceev faj: Ib txwm txiav lub hwj chim thiab xyuas qhov tsis muaj hluav taws xob ua ntej kho; daim ntawv lo cov khoom ua ntej disassembly; thiab khaws cov ntaub ntawv kho kom ntxaws.
Kauj Ruam 3: Ua kom muaj kev nyab xeeb yog qhov tseem ceeb tshaj plaws
Cov txheej txheem txheej txheem yuav tsum ua raws:
Ua kom tiav Lub Hwj Chim Fais Fab: Ua ntej ua ib qho kev soj ntsuam lossis kev saib xyuas nrog rau sab hauv ntawm lub txee hluav taws xob, lub zog tseem ceeb rau cov khoom siv yuav tsum raug muab tua, thiab "Power Off - Test for Voltage - Tag - Lockout" yuav tsum ua raws li cov txheej txheem. Cov khoom siv xws li cov tsav tsheb sib txawv (VFDs) tuaj yeem khaws cov khoom siv hluav taws xob zoo tom qab txiav hluav taws xob; tos tsawg kawg 5 feeb lossis ntev dua kom txog thaum cov nqi seem tau tag nrho dissipated.
Kev tuav kom zoo: Tsis txhob kov cov khoom siv hluav taws xob nrog ob txhais tes ntub dej. Thaum hloov cov khoom xws li relays, siv cov cuab yeej tsim nyog.
Cov Khoom Siv Tiv Thaiv Tus Kheej: Cov neeg ua haujlwm yuav tsum hnav khaub ncaws ua haujlwm nyab xeeb, khau kev nyab xeeb, thiab lwm yam khoom siv tiv thaiv. Plua plav tsim thaum lub sij hawm ntxuav kuj yuav ua rau muaj teeb meem; nws raug pom zoo kom hnav lub npog ntsej muag.
Ua raws li Cov Txheej Txheem Zoo: Ua raws li cov txheej txheem pib ntawm "tig lub rhaub ua ntej, tom qab ntawd pib lub ntsiab chav tsev," thiab ua qhov sov so - nce qib ntawm "khiav lub ntsiab ntawm qhov qis ceev rau 5 feeb."
