1. **Stratified Troubleshooting:** Ua ntej txheeb xyuas qhov loj, Tom qab ntawd muab qhov tob dua
Qhov no yog cov txheej txheem kev kuaj mob tseem ceeb, ua raws li qhov kev txiav txim ntawm "Cov khoom tiav → Ua haujlwm → Hluav taws xob":
Yog tias cov khoom siv ua haujlwm, tab sis cov khoom tiav lawm muaj teeb meem (tsis sib haum ntsoog / ntawv tawg / qhov sib txawv ntawm qhov sib txawv): ncaj qha txheeb xyuas qhov nro tswj / ntsuas encoder ua txhaum; tsis txhob nkim sij hawm los xyuas cov khoom siv hluav taws xob.
Yog tias cov cuab yeej tsis pib tag nrho / qhov taw qhia teeb tawm: Ua ntej xyuas cov khoom siv hluav taws xob thiab kev nyab xeeb; Tom qab tshem tawm cov teeb meem yooj yim, xyuas PLC.
Yog tias qhov kev ua txhaum tsis raug, daws nrog kev pib dua, thiab rov ua dua: ncaj qha tshawb xyuas cov teeb meem cuam tshuam; tsis txhob dig muag hloov cov khoom.
2. **Txoj Kev Tshawb Fawb Hloov Kho:** Txheeb xyuas cov khoom puas
Rau cov khoom uas nyuaj rau kev ntsuas, xws li Circuit Court boards thiab sensors, siv txoj kev hloov yuav txuag tau ib nrab ntawm lub sijhawm:
Piv txwv li, yog tias koj xav tias qhov puas 7805 voltage regulator nyob rau hauv lub photoelectric tiv thaiv Circuit Court, ncaj qha hloov nws nrog ib tug tshiab ntawm tib qauv rau kev kuaj. Yog tias nws ua haujlwm tom qab hloov pauv, qhov txhaum tau lees paub; tsis tas yuav rov ntsuas qhov voltage.
Yog tias koj xav tias ib qho txawv txav sensor, hloov nws nrog lub sensor ua haujlwm ntawm tib tus qauv. Yog hais tias qhov txhaum ploj mus, lub sensor yog qhov teeb meem, txiav txim siab tawm qhov ntsuas thiab teeb meem thaiv.
3. Parameter Comparison Method: Tshem tawm tib neeg sai sai -Ua txhaum
Rau parameter - cuam tshuam xws li kev sib txuas lus thiab kev nro, sib piv cov chaw tam sim no nrog cov qauv parameter cov lus:
Rau kev sib txuas lus tsis raug, ua ntej xyuas qhov chaw nres tsheb thiab tus nqi baud. Yog tias lawv tsis ua raws li qhov yuav tsum tau ua, kho lawv ncaj qha . 80% ntawm tib neeg- kev sib txuas lus yuam kev tuaj yeem daws tau ncaj qha. Rau qhov tsis ruaj khov, sib piv cov kev nro tam sim no nrog cov uas siv hauv kev tsim khoom ib txwm muaj. Yog tias qhov sib txawv dhau ntawm qhov tsim nyog, rov qab kho lub Hoobkas teeb tsa thiab tom qab ntawd zoo -tune.
4. Txoj kev sib cais thiab cais tawm: Sib txawv ntawm cov khoom siv hluav taws xob thiab hluav taws xob
Rau kev ua txhaum xws li lub cev muaj zog tsis tig los yog overcurrent tshaj tawm, disconnecting lub load tuaj yeem txheeb xyuas qhov ua rau:
Disconnect qhov kev sib txuas ntawm lub cev muaj zog thiab DC chav tsev. Yog hais tias qhov txhaum tshwm sim tom qab rov pib lub tsev, nws yog qhov txhaum cai (DC unit). Yog tias tsis muaj qhov yuam kev, nws yog kev sib tsoo ntawm cov neeg kho tshuab lossis lub cev muaj zog, tshem tawm qhov kev xav tau rov qab los daws teeb meem hauv ntu hluav taws xob.
5. Hom Fault Quick Reference Techniques: Match Faults to Faults kom txuag sij hawm
Nco ntsoov cov yam ntxwv ntawm cov kev ua txhaum ntau rau kev txheeb xyuas yooj yim:
Yog tias tus choj rectifier hlawv sai sai tom qab hloov → ncaj qha hloov 7805 voltage regulator; 90% ntawm lub sij hawm, nws yog lub rectifier ua rau luv luv Circuit Court.
Yog tias qhov txhaum rov tshwm sim dua thiab txhim kho tom qab rov pib dua → ncaj qha mus saib cov av thiab xaim; nws yog qhov tseeb electromagnetic cuam tshuam.
Rau kev sib txuas lus faults, xyuas qhov tsis ua ntej, tom qab ntawd qhov kev txiav tawm ntawm qhov hluav taws xob, thiab thaum kawg ntawm kev xaim; kev tshuaj xyuas los ntawm qhov muaj feem ntau mus rau qhov tshwm sim tsawg yog txoj hauv kev raug.
Rau armature overvoltage, kho qhov tsis ua ntej (ntxiv acceleration / deceleration), ces kos lub encoder; tsis tas yuav disassemble lub cuab yeej ncaj qha.
6. Cov lus qhia txog kev kuaj xyuas kev nyab xeeb
Ua ntej fais fab tuag -tawm txij nkawm, thaij duab los sau cov xov tooj ntawm tes kom tsis txhob rov xa xov tsis raug thiab qhov ua tsis zoo thib ob. Thaum ntsuas qhov hluav taws xob, ntsuas cov kab hluav taws xob nkag ua ntej, tom qab ntawd cov ceg; Kev ntsuas los ntawm cov davhlau ya nyob twg mus rau qhov tshwj xeeb terminals yog qhov ua tau zoo dua.
