1. Fais fab mov/Circuit Board Failure (feem ntau Easily Misdiagnosed) Qhov no yog feem ntau cov hluav taws xob txhaum nyob rau hauv lub chav da dej rewinding tshuab. Cov tsos mob tshwm sim yog kev tiv thaiv kev tiv thaiv photoelectric tsis ua haujlwm: lub tshuab txiav tsis nres txawm tias thaum lub photoelectric sensor raug them. Hloov cov burnt -tawm fais fab choj rectifier ua rau lub rectifier tshiab hlawv sai sai dua.
Qhov laj thawj: Ib qho hluav taws kub -tawm choj rectifier ua rau lub voj voog luv, ua rau peb -terminal voltage regulator (7805). Hloov tsuas yog tus choj rectifier tsis hloov lub voltage regulator yuav tsis daws qhov teeb meem.
2. PLC System cuam tshuam tsis ua haujlwm (Feem ntau rov tshwm sim) Cov tsos mob tshwm sim: PLC qhov teeb meem txhaum cai teeb pom kev zoo, qee qhov tsav nres tsis xwm yeem, thiab lub tshuab ceev dheev tsis ruaj khov. Qhov teeb meem raug daws tom qab lub zog hluav taws xob thiab rov pib dua, tab sis rov tshwm sim tom qab lub sijhawm ua haujlwm.
Qhov laj thawj tseem ceeb: Kev xaim tsis raug (sib xyaw siab -voltage thiab qis-voltage wiring, chaotic grounding), los yog electromagnetic cuam tshuam los ntawm ib puag ncig cov khoom siv hluav taws xob, tuaj yeem ua rau PLC cov ntaub ntawv yuam kev thiab cov txiaj ntsig tsis zoo ntawm cov khoom siv hluav taws xob.
3. Kev sib txuas lus tsheb tsis ua haujlwm (feem ntau yog tib neeg-Induced)
Cov tsos mob tshwm sim: Qee cov ntsiab lus tsav tsis teb rau kev tswj hwm, lub kaw lus ncaj qha qhia txog kev sib txuas lus yuam kev, thiab cov txheej txheem tsim khoom tsis tuaj yeem pib.
Feem ntau Cov Uas Muaj Feem Ntau (Nqe los ntawm tus lej):
① Kev sib txuas lus tsis raug teeb tsa (chaw nres tsheb tooj, baud tus nqi, thiab qhov system tsis sib haum; tib neeg yuam kev suav rau qhov feem ntau);
② Burned-tawm los yog offset resistor thaum kawg ntawm lub npav, ua rau chaotic teeb liab xav txog;
③ Kev sib xyaw ua ke ntawm kev sib txuas lus thiab hluav taws xob cables, ua rau muaj teeb meem cuam tshuam thiab cuam tshuam.
4. DC tsav tsis ua haujlwm
Cov tsos mob tshwm sim: Lub cev muaj zog tsis tuaj yeem pib, DC tsav qhia txog armature overvoltage / overcurrent / undervoltage txhaum cai, los yog lub tshuab ceev yuav tsis ruaj tsis khov.
Cov teeb meem tshwm sim:
Armature Overvoltage: Ntau dhau inertia los ntawm daim ntawv ejector cov menyuam ua rau overvoltage hauv lub tshuab hluav taws xob; kho qhov ntsuas yuav daws qhov no.
Armature Overcurrent: luv luv hauv Circuit Court lossis kev laus thiab kev tawg ntawm cov khoom hauv DC tsav.
Undervoltage: xoob lossis kev sib cuag tsis zoo ntawm cov input terminals ua rau lub zog tsis txaus. Ntev -lub sij hawm raug kub siab, plua plav, thiab av noo tuaj yeem ua rau DC tsav mus rau hnub nyoog thiab ncaj qha ua rau lub tshuab tsis ruaj khov.
5. Kev Tswj Tsis Txaus Siab (feem ntau cuam tshuam cov khoom zoo)
Cov tsos mob tshwm sim: Cov cuab yeej ua haujlwm ib txwm ua, tab sis cov ntawv yob cov ntawv ua tiav muaj qhov tsis sib xws, cov ntawv tsis tu ncua, wrinkles, lossis tawg.
Cov laj thawj tseem ceeb: cuam tshuam nrog lub teeb liab nro sensor, tsis tsim nyog qhov teeb meem tsis sib haum xeeb, lossis qhov txawv txav encoder ceev tawm tswv yim ua rau ntau qhov sib txawv ntawm qhov tseeb nro thiab cov nqi teeb tsa, ua rau muaj kev sib hloov ntawm qhov nro.
