Automotive relay yog ib qho khoom siv hluav taws xob tswj hluav taws xob uas ua haujlwm los ntawm kev siv me me tam sim no los tswj cov tam sim no loj. Nws lub luag haujlwm tseem ceeb suav nrog kev hloov kho tsis siv neeg, kev tiv thaiv kev nyab xeeb, kev hloov hluav taws xob, thiab hloov pauv. Thaum lub automotive relay malfunctions, tej yam tsheb ua hauj lwm yuav tsis ua hauj lwm zoo.
Txhawm rau ntsuas qhov xwm txheej ntawm lub tsheb relay, cov hauv qab no tuaj yeem siv:
Ib lub relay yog ib qho khoom siv hluav taws xob tswj uas tuaj yeem muab cov khoom tso tawm kom muaj nuj nqis thiab tuav lub sijhawm txaus los ua kom muaj kev hloov pauv hloov pauv hauv cov tswj kom muaj nuj nqis hauv hluav taws xob tawm hluav taws xob. Thaum cov tswv yim txo qis mus rau ib theem thiab tseem nyob rau lub sijhawm ntev txaus, lub kaw lus yuav rov qab mus rau nws lub xeev thawj zaug.
1. Siv lub stethoscope lossis koj txhais tes kom hnov yog tias lub relay clicks lossis vibrates. Yog tias muaj, nws feem ntau ua haujlwm raug.
2. Siv digital multimeter los ntsuas qhov coil tsis kam ntawm relay. Feem ntau nws yuav tsum yog qis dua 2kΩ.
3. Nrog lub hwj chim tawm, ntsuas qhov kev tiv thaiv ntawm qhov ib txwm kaw kev sib cuag thiab lub davhlau ya nyob twg. Qhov kev tiv thaiv yuav tsum nyob ze rau xoom lossis qis heev.
Kev sib koom ua ke cov kev sim no tuaj yeem txiav txim siab qhov xwm txheej ntawm lub tsheb relay. Hauv kev xyaum, kev tshuaj xyuas dav dav raws li qhov xwm txheej tshwj xeeb yog tsim nyog kom tsis txhob poob vim kev txiav txim tsis raug.
