1.Kuaj xyuas lub cev puas tsuaj
Nrhiav cov cim qhia tias cov pa taws ua khawv koob tsis tau tso tawm. Tshawb xyuas lub tsev thiab nws qhov chaw nyob ib puag ncig kom paub tseeb tias tsis muaj cov pa taws uas yuav qhia tau tias cov khoom siv hluav taws xob tsis ua haujlwm. Yog tias muaj cov cim qhia tias muaj ib yam dab tsi tau kub hnyiab, tua lub hwj chim input thiab ceeb toom rau lub tuam tsev hluav taws xob uas yuav tsum tau hloov kho.
2.Ua pov thawj lub zog nkag
Muaj lub hwj chim qhov chaw muab lub hwj chim rau VFD thiab nws yog lub sij hawm los xyuas kom meej tias tsis muaj dab tsi cuam tshuam qhov chaw fais fab no. Nws yog ib qho tseem ceeb los xyuas cov khoom xws li fuses, Circuit Court breakers thiab upstream disconnects kom paub tseeb tias lawv tsis zoo thiab npaj ua haujlwm. Cov ntsuas tsim nyog yuav tsum tau siv thiab tsis txhob sim yam tsis muaj kev cob qhia kom raug thiab ua raws li cov cai ntawm tuam txhab kev nyab xeeb.
3 Txheeb xyuas cov lej txhaum cai
Fault codes yog ib txoj hauv kev zoo kom nkag siab txog teeb meem dab tsi uas tus tsav tau ntsib thiab ua rau. Thaum lawv sib txawv ntawm cov chaw tsim khoom rau cov chaw tsim khoom, muaj qee qhov yuam kev uas yuav taw qhia rau qhov teeb meem uas koj tab tom ntsib. Lub ntsiab faults yog:
- Overvoltage - voltage ntsuas ntawm lub tsheb npav DC siab dua li qhov yuav tsum tau ua
- Overcurrent - lub cev muaj zog tam sim no tshaj qhov pom tau FLA ntawm daim ntawv tsav tsheb
- Overheating - tsav / lub cev muaj zog overheating
- Lub cev muaj zog tshaj - lub cev muaj zog khiav ntawm qib siab dua li tsim los rau lub sijhawm ntev
- Av txhaum - ua rau VFD grounding
- Undervoltage - tsis txaus voltage yog muab los them rau DC Bus
Kev ua tsis tiav tuaj yeem ua rau koj nkag siab txog qhov tshwm sim thiab kev kho kom rov qab mus rau tom ntej. Ntau VFDs muaj keeb kwm tsis ua haujlwm, uas yog qhov chaw zoo los pib rov qab engineering dab tsi tshwm sim.
4.Kuaj xyuas qhov kev khiav thiab zaus siv cov cim qhia
Lub VFD yuav tsis khiav yam tsis muaj kev hais kom ua. Thaum qhov no zoo li yooj yim txaus, ntau tus kws tshaj lij siv sijhawm ntev dhau mus rau txoj kev tsis ncaj ncees lawm, tsuas yog paub tom qab tias VFD tsis tau muab cov lus txib kom raug. Ntxiv rau qhov kev tawm tswv yim no, yuav tsum muaj lub cim qhia zaus los qhia rau VFD qhov tso zis nws yuav tsum muab. Ib qho kev daws teeb meem zoo yog hloov lub tsav los ntawm cov chaw taws teeb mus rau hauv zos thiab sim khiav lub tsav manually. Nco ntsoov tias lub cev muaj zog yuav khiav ua qhov no, yog li koj yuav tsum tau ua tib zoo saib xyuas cov load ntawm tus tsav kom muaj kev nyab xeeb. Yog tias qhov no ua rau VFD khiav, koj tuaj yeem cais cov teeb meem ntxiv rau cov peev txheej no txij li koj tau txheeb xyuas qhov teeb meem hauv qab no.
5.Ua kom ntseeg tau tias qhov chaw nres tsheb tau txaus siab
Txhua lub voj voog kev nyab xeeb yuav tsum raug kaw kom ntseeg tau tias cov kev tswj xyuas tau txaus siab. Qhov no suav nrog cov khoom xws li kev nyab xeeb torque tawm sensors, thermal sensors, thiab lwm yam kev nyab xeeb hloov uas tiv thaiv kev tsav tsheb los txhim kho kev nyab xeeb tag nrho. Yog tias ib qho ntawm cov khoom no qhib, lub voj voog ua haujlwm raws li tsim, uas yuav txwv tsis pub ua haujlwm VFD.
