Yuav ua li cas kuaj lub solenoid nrog lub multimeter
Lub solenoid yog cov khoom siv hluav taws xob ntau, feem ntau yog ua los ntawm cov hlau, los tsim ib qho chaw electromagnetic. Phau ntawv qhia no qhia koj yuav ua li cas ntsuas nws nrog multimeter.
Hauv phau ntawv qhia no, peb yuav taug kev koj los ntawm cov txheej txheem ntawm kev sim lub solenoid nrog lub multimeter. Koj yuav xav tau ib tug multimeter, koob qhov ntswg pliers thiab ib tug ntswj ntsia hlau.
Kev ntsuas lub solenoid tsis zoo li kev sim lwm yam khoom siv hluav taws xob. Tus qauv tsim ntawm lub solenoid yog xws li cov qauv kev tiv thaiv lossis kev soj ntsuam txuas ntxiv tsis tuaj yeem siv. Hmoov zoo, koj tuaj yeem siv lub ohmmeter los ntsuas lwm qhov ntawm lub kaw lus kom paub seb qhov twg ua tsis tiav.
Solenoid yog dab tsi?
Lub solenoid yog ib qho khoom siv hluav taws xob uas hloov hluav taws xob hluav taws xob mus rau lub zog hluav taws xob. Nws muaj cov coil qhov txhab nyob ib ncig ntawm cov tub ntxhais hlau uas ua haujlwm zoo li lub plunger lossis piston. Thaum hluav taws xob hla lub kauj, nws tsim ib qho chaw electromagnetic uas ua rau lub piston txav mus rau hauv thiab tawm, nyiam txhua yam nws txuas nrog. (1)
Kauj ruam 1: Teem lub multimeter mus rau qhov tseeb muaj nuj nqi
- Ua ntej, teeb lub multimeter mus rau qhov chaw ohm. Om tuning yog sawv cev los ntawm Greek cim Omega. (2)
- Thaum kuaj lub solenoid nrog lub multimeter, koj yuav tsum kov lub solenoid terminals nrog dub thiab liab multimeter probes.
- Cov hlau dub yuav tsum tau txuas nrog lub davhlau ya nyob twg tsis zoo. Ntawm qhov tsis sib xws, cov xaim liab yuav tsum tau txuas nrog lub davhlau ya nyob twg zoo.
Kauj Ruam 2: Tshawb Nrhiav Qhov Chaw
- Teem lub multimeter rau "Ohm". Lub Ohm parameter tso cai rau koj los xyuas qhov txuas ntxiv. Muab cov multimeter sojntsuam rau ntawm lub solenoid terminals, feem ntau yog nyob rau sab saum toj ntawm lub tsev solenoid.
- Kov ib qho kev sojntsuam mus rau lub davhlau ya nyob twg cim "S" ntawm lub tsev solenoid. Kov lwm qhov kev sojntsuam mus rau lwm lub davhlau ya nyob twg.
- Txheeb xyuas qhov kev nyeem ntawv ntawm lub vijtsam multimeter rau cov cim qhia ntawm kev txuas ntxiv lossis tsis muaj zog hauv 0 txog 1 ohm ntau yam. Yog tias koj tau txais qhov kev nyeem no, nws txhais tau tias tsis muaj teeb meem nrog lub solenoid.
Kauj ruam 3: Tshawb xyuas koj lub multimeter
Yog tias koj lub solenoid ua haujlwm tau zoo, qhov kev nyeem ntawv ntawm lub tshuab hluav taws xob yuav tsum nyob nruab nrab ntawm 12 thiab 24 volts. Yog tias nws tsis yog, nws tuaj yeem yog teeb meem ntawm kev xaim lossis luv luv hauv Circuit Court. Xyuas kom tseeb tias nws tau txais lub zog txaus los ntawm kev sib txuas cov khoom thauj, xws li LED, mus rau lub solenoid lub davhlau ya nyob twg thiab txuas lub multimeter rau lawv. Yog tias koj kos duab tsawg dua 12 volts, koj muaj teeb meem ntawm kev xaim uas koj yuav tsum tau kho los ntawm kev kuaj xyuas qhov hluav taws xob tawm ntawm lub rooj tsavxwm.
Koj tuaj yeem siv multimeter los xyuas seb lub solenoid puas txuas tau zoo. Nrog lub solenoid positioned raws li qhia, rub tus txhais thiab maj mam siv voltage rau lub terminals. Lub 'meter' yuav tsum nyeem 12 volts thiab maj mam poob raws li tam sim no ntws los ntawm solenoid. Yog tias nws tsis yog, kho thiab sim dua kom txog thaum nws ua.
Nyeem tau zoo tab sis tsis ua haujlwm
Txheeb xyuas qhov kev nyeem ntawv ib txwm tab sis tsis ua haujlwm txhais tau hais tias qhov kev tiv thaiv yog OK thiab cov relay yog energized nrog multimeter. Txoj kev no peb tuaj yeem paub seb nws puas yog hluav taws xob lossis tshuab tsis ua haujlwm. Cov txheej txheem yog ua nyob rau hauv 3 theem:
Kauj Ruam 1: Txheeb xyuas qhov tsis kam ntawm solenoid nrog lub multimeter.
Tig lub multimeter thiab teeb nws nyeem hauv ohms. Muab qhov kev sojntsuam zoo rau ntawm ib lub davhlau ya nyob twg thiab qhov kev sojntsuam tsis zoo ntawm lwm lub davhlau ya nyob twg. Kev nyeem ntawv yuav tsum nyob ze rau xoom, qhia txog kev sib txuas zoo ntawm ob lub terminals. Yog tias muaj kev nyeem ntawv, muaj teeb meem nrog lub solenoid.
Kauj Ruam 2. Qhib lub solenoid nrog lub multimeter thiab xyuas nws cov haujlwm.
Txhawm rau ua kom lub zog solenoid, siv lub multimeter hauv AC voltage hom kom paub tseeb tias nws muaj zog thaum nws yuav tsum ua haujlwm. Tom qab ntawd siv lub ammeter (lub ntsuas hluav taws xob tam sim no) los ntsuas qhov tam sim no ntws los ntawm nws. Cov kev nyeem no tuaj yeem qhia rau koj yog tias koj muaj lub zog txaus lossis yog tias koj muaj lub solenoid phem.
Kauj Ruam 3: Tshawb xyuas Solenoid Ua Haujlwm nrog Relay
Yog hais tias lub solenoid qhia tau hais tias ib txwm nyeem ntawv, tab sis tsis hloov lub tsheb, nws yog ib qho tsim nyog yuav tau xyuas qhov kev ua haujlwm ntawm solenoid siv lub relay. Tshem tawm cov hluav taws xob txuas los ntawm kev sib kis thiab txuas lub jumper ntawm lem 1 thiab 2-3. Yog hais tias lub solenoid txav, ces qhov teeb meem yog feem ntau faulty relay los yog thaiv.
Txheeb xyuas qhov tsis kam ntawm solenoid nyob rau hauv tag nrho nws cov circuits. Txuas ib qho kev xeem coj mus rau ib lub xaim ntawm lub solenoid thiab nias rau lwm cov hlau mus rau lwm cov hlau li tsib vib nas this. Txheeb xyuas qhov txuas ntxiv los ntawm kev hloov cov xov hlau kom txog thaum koj mus txog qhov qhib Circuit Court. Rov ua cov txheej txheem no rau txhua qhov ntawm peb cov xov hlau hauv ob lub voj voog.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Teeb lub multimeter rau lub tsheb roj teeb
- Yuav ua li cas nrhiav tau ib tug luv luv Circuit Court nrog ib tug multimeter
- Yuav ua li cas txheeb xyuas qhov voltage ntawm 240 V nrog multimeter?
