Ntau tus neeg siv khoom ntsib tib lub taub hau thaum mus yuav khoom rau gensets: cov khoom siv uas zoo li tshiab thiab tuaj nrog tus nqi tsis txaus ntseeg, tsuas yog ua kom tawg tag thaum muaj hluav taws xob tua. Qhov no yuav luag ib txwm ua lag luam ntxiab-cov khoom siv kho kom zoo nkauj tau kho kom zoo nkauj thiab dhau mus ua hom khoom lag luam- cov khoom siv tshiab.
Raws li tus kws tshaj lij lub tshuab hluav taws xob daws teeb meem, WAGNA tau pom dhau los ntawm kev ua haujlwm hauv ntau xyoo uas dhau 30% ntawm lub zog tam sim ntawd txuas nrog cov khoom siv tsis raug, txhua qhov rov qab mus rau cov kev dag ntxias no uas zoo li tshiab tab sis ua tsis zoo.
Kev lag luam txij nkawm kev txheeb xyuas pleev xim rau daim duab meej: gensets refurbished muaj qhov ua tsis tiav ntawm 300% -500% siab dua li cov chav tshiab tshiab, nrog cov nqi tu tu ncua tas mus li ntau dua 40%. Cov koog no tau txais txiaj ntsig zoo rau lub sijhawm foob pob tawg - lawv lub sijhawm tsis ua haujlwm thiab qhov hnyav yog qhov tsis tuaj yeem pom zoo.
Txhawm rau pab koj tshem tawm cov kev pheej hmoo zoo li no, WAGNA tau tsim cov txheej txheem tshuaj xyuas theem, sib txuas cov kev tshuaj ntsuam sai thiab hauv - kev txheeb xyuas qhov tob, ua rau ntau xyoo ntawm kev paub dhau los. Txawm tias tsis yog - cov kws tshaj lij tuaj yeem txiav txim siab qhov tseeb ntawm cov hloov pauv nrog cov kab ke no.
I. Kev tshuaj ntsuam ceev: 5 Qhov Chaw Tshawb Xyuas Tseem Ceeb & Kev Ntsuam Xyuas Kev Nyab Xeeb
Txawm tias tom qab kho kom zoo nkauj, refurbished alternators yuav luag ib txwm tso cov cim qhia hauv cov ntsiab lus. Koj tuaj yeem ua qhov kev ntsuam xyuas ua ntej nrawm uas siv cov lus ntsuas kev pheej hmoo hauv qab no:
|
Chaw soj ntsuam |
Kev nyab xeeb Indicators (Low Risk) |
Red Flag Indicators (High Risk) |
Technical Rationale & Impact |
|
Ntug & Seams |
Smooth, ib txwm xim xim; huv residue-dawb ntug |
Tsis zoo li qub, tshiab - tshwm xim; cov xim qub / xeb pom ntawm ntug |
Tej zaum yuav nkaum hauv corrosion, cuam tshuam cov qauv load-cov kabmob muaj peev xwm |
|
Nameplate & Markings |
Permanently affixed (riveted/laser-engraved) nameplate; cov ntaub ntawv yog tseeb thiab officially verifiable |
Cov ntawv sau tsis zoo, cov ntsiab lus tsis txaus ntseeg, lossis cov lej tsis raug lees paub |
Zoo li ib tug cobbled- ua ke; Kev ua haujlwm rwb thaiv tsev tsis ua raws li GB cov qauv |
|
Lim kev sib txuas |
Kev sib txuas huv huv; roj muaj ib tug natural, zoo ib yam xim |
Cov roj qub qub tam sim no; roj yog unnaturally ntshiab (tsis ntev los no hloov mus nkaum qhov paug) |
Cov pa roj carbon ntau dhau; thermal efficiency tuaj yeem poob los ntawm 15-25%, nyob ntawm qhov tso nyiaj hnyav |
|
Ua haujlwm nrov nrov |
Yooj yim pib; khov kho, tsis tu ncua tsis muaj -load haujlwm |
Knocking lossis irregular kev sib txhuam suab nyob rau hauv load |
Ntau dhau bearing clearance; Cov qib vibration tuaj yeem dhau ISO 10816 txwv |
|
Tso pa tawm |
Lub teeb grey pa luam yeeb uas tsis muaj plume txuas ntxiv |
Tsis tu ncua tsaus nti dub lossis xiav tso pa tawm |
Kev puas tsuaj tsis tiav, ua rau tsis muaj - ua raws li cov pa tawm thiab txo cov zis hluav taws xob |
II.In-Kev Ntsuas qhov tob: 3-Tier Progressive Inspection System
Kauj Ruam 1: Kev soj ntsuam zoo li qub (Kev Tshawb Fawb Txog Lub Cev)
1, Kev nthuav dav & Kev kuaj xyuas
Siv lub teeb ci siab - siv lub teeb nyem los tshuaj xyuas lub tog raj kheej thaiv qhov chaw mating, ntsia liaj qhov rooj ntug, thiab cov hlua hlau txuas rau oxidation. Tshawb xyuas lub txee tswj cov ntsia hlau rau cov cuab yeej cim los ntawm kev rov ua dua thiab ua kom nruj.
2, Tus Kheej & Cov ntaub ntawv pov thawj
Hla- txheeb xyuas tias tus qauv, tus lej cim, thiab hnub tsim khoom ntawm lub tshuab hluav taws xob, lub cav, thiab cov npe hloov pauv hloov pauv tau zoo ib yam thiab pom tau. Siv tau cov lej xov tooj ntawm cov chaw tsim khoom lag luam thaum twg los tau.
3, Cov cuab yeej tshwj xeeb kuaj xyuas
If available, use an industrial endoscope to inspect for cylinder carbon buildup. Use an insulation resistance tester (megohmmeter) to measure winding insulation-new units typically show >2 MΩ kuj nyob rau hauv qhuav tej yam kev mob.
Qib 2: Kev Ntsuam Xyuas Kev Ua Haujlwm Dynamic (Kev Ntsuas Tiag - Sijhawm Ua Haujlwm)
Kev ntsuam xyuas kev ua haujlwm zoo tshaj plaws muab qhov kev pom tseeb tshaj plaws rau hauv genset qhov kev ua haujlwm tiag tiag. Siv cov kev lag luam hauv qab no- cov qauv ntsuas raws li koj qhov kev siv:
|
Test Phase |
Pass Standard |
Kev Tshawb Fawb Txog Kev Tshawb Fawb |
|
Cold Start Test |
Pib ruaj khov hauv 15 vib nas this, tsis muaj suab nrov txawv txav |
Sau pib- lub sijhawm nce thiab nce siab pib tam sim no |
|
Tsis muaj -Load Stability |
Voltage fluctuation < ± 2%, zaus Kev hloov pauv < ± 1% |
Siv lub zog zoo ntsuas ntsuas los sau cov ntawv waveforms |
|
50% Load Test |
Voltage fluctuation < ± 3%, tso pa tawm yog lub teeb grey |
Saib xyuas cov kabmob kub qhov sib txawv (nyob rau hauv tib lub sijhawm ua haujlwm, feem ntau <10 degree) |
|
75% Load Test |
Voltage fluctuation < ± 5%, suab hloov tau zoo |
Ntsuas tag nrho chav tsev vibration nqi (saib rau ISO 10816 tus qauv) |
Qib 3: Cov ntaub ntawv & Serial Number Verification
1, Thov cov ntaub ntawv tseem ceeb
Tau txais daim ntawv xa nyiaj yuav khoom, cov ntawv pov thawj cov chaw tsim khoom (nrog rau cov lus qhia meej meej pib hnub tim thiab kev pab them nqi), daim ntawv pov thawj Hoobkas ntawm kev ua raws, thiab thawj tus neeg siv phau ntawv qhia. Cov gensets kho dua tshiab yuav luag ib txwm tsis ua tiav, nce - mus rau - hnub, thiab tag nrho cov ntaub ntawv tsim khoom lag luam zoo sib xws.
2, validate serial tooj
Sau cov naj npawb ntawm ob lub cav thiab alternator. Txheeb xyuas lawv ntawm cov chaw tsim khoom cov kev txhawb nqa los yog cov neeg muag khoom tso cai, thiab hla - txheeb xyuas cov ntaub ntawv tsim khoom ntawm lub Hoobkas thiab cov xwm txheej lav.
3, Xav tau cov ntaub ntawv xeem
Xav kom koj tus neeg muag khoom muab cov ntaub ntawv tseem ceeb ntawm kev ua haujlwm los ntawm kev ua haujlwm ntawm lub Hoobkas thiab kev sim ua haujlwm, suav nrog cov qauv hluav taws xob thiab zaus waveforms, nrog rau ntev -ntev sijhawm tag nrho- cov ntaub ntawv kuaj xyuas.
III. Phau Ntawv Qhia Kev Tiv Thaiv Kev Muag Khoom: Mitigate Risks ntawm Qhov Chaw
Ua raws li cov kauj ruam no kom tsis txhob muaj feem ntau ntawm cov kev pheej hmoo thaum kev yuav khoom:
1, Kev Pabcuam Ua Haujlwm Zoo
Ua ntej lub Hoobkas ua ntej - tso cai cov neeg faib khoom
Txheeb xyuas qhov siv tau ntawm lawv daim ntawv tso cai tso cai
Tshawb xyuas lawv lub tsev rau khoom thiab ntawm -cov khoom muag
2, Daim ntawv cog lus tiv thaiv
Kom meej meej txhais "brand-tshiab, thawj cov khoom siv tiag tiag"
suav nrog ua ntej- kev tshuaj xyuas kev xa khoom thiab xa rov qab cov nqe lus
Qhia meej txog kev puas tsuaj rau kev qhia tsis tseeb
3, Kev lees paub raws cai
Txuas cov ncauj lus kom ntxaws txog kev lees paub
Txhais ntawm -cov khoom xeem ntawm lub vev xaib thiab cov txheej txheem dhau / tsis ua haujlwm
Qhia txog cov txheej txheem rau kev tuav cov khoom tsis raug cai -
Kev nqis peev hauv genset yog qhov tseem ceeb rau kev tiv thaiv koj cov khoom lag luam ruaj khov. WAGNA ceeb toom koj: yog tias tus nqi zoo li zoo dhau los ua qhov tseeb, nws yuav yog. Yog tias koj muaj kev tsis ntseeg, nco ntsoov xyuas. Rau kev txhawb nqa kev tshaj lij nrog kev txheeb xyuas lossis kev pab xaiv, hu rau WAGNA Technical Support Hotline: 400-0757-022.
