Taw qhia rau lubpib relay
Lub oob khab relay yog ib feem ntawm tag nrho lub tsheb Circuit Court rau lub cav thiab roj teeb ua haujlwm ua ke. Yog hais tias tus yuam sij tau tig mus rau lub xeev ON, lub electromagnet yuav muaj zog kom tau txais nws cov hniav sib khi rov qab mus rau nws lub xeev kaw. Cov hluav taws xob tam sim no yuav ntws los ntawm tus hniav tus pin mus rau hauv relay coil los pib qhov kev hloov pauv tag nrho kom kaw lub voj voog kom ntseeg tau tias lub cav yuav nquag pib.
Pib relay xeem txoj kev
1. Multimeter xeem txoj kev
Siv ib qho kev ntsuas multimeter yog txoj kev siv ntau tshaj plaws rau kev kuaj xyuas pib relays. Ua ntej tshaj plaws, ntxig tus cwj mem liab ntawm lub multimeter mus rau hauv lub davhlau ya nyob twg ntawm lub relay coil, tom qab ntawd hauv av cov ntawv xeem dub, qhib lub qhov rooj tsheb, uas tuaj yeem ua tau. Nws suav nrog lub suab tam sim ntawm lub teeb tawm lub teeb tawm, uas tuaj yeem hnov los txheeb xyuas seb lub relay puas ua haujlwm zoo. Yog tias koj tsis hnov lub suab ntawm lub tsheb teeb los, ces koj yuav tsum hloov lub relay
2. Kev sim siv lub voltmeter
Kev sim siv lub voltmeter kuj yog ib txoj hauv kev ib txwm muaj, thiab nws yuav muab kev yooj yim thiab ceev kev txheeb xyuas seb cov relays ua haujlwm raug lossis tsis yog. Ntxig qhov kev ntsuam xyuas liab ntawm lub voltmeter mus rau hauv lub relay coil zoo davhlau ya nyob twg, tom qab ntawd hauv av kuaj dub. Tom ntej no, tig tus yuam sij rau txoj haujlwm ON. Yog tias qhov ntsuas hluav taws xob nyeem los ntawm qhov ntsuas no nyob ze 12 volts, lubrelay yog zoo; txwv tsis pub, nws yuav tsum tau hloov.
3. Kev sim siv lub oscilloscope
Piv nrog rau cov txheej txheem saum toj no, kev sim los ntawm oscilloscope yog txoj kev sim siab dua, uas ob qhov kev sojntsuam ntawm oscilloscope yuav tsum tau txuas nrog ob lub davhlau ya nyob twg ntawm relay coil. Tom qab ntawd soj ntsuam waveform hloov ntawm oscilloscope. Yog tias qhov hloov pauv waveform yog qhov qub, ces lub relay ua haujlwm zoo; txwv tsis pub, lub relay yuav tsum tau hloov.
Kev daws teeb meem rau qee yam teeb meem
Kuv yuav ua li cas yog tias qhov pib relay tsis tuaj yeem ua haujlwm zoo?
Ib qho luv luv lossis qhib Circuit Court hauv Circuit Court tuaj yeem ua haujlwm tsis zoo ntawm qhov pib relay, yog li seb qhov cuam tshuam ntawm Circuit Court puas yuav tsum tau kuaj xyuas thiab kho raws sijhawm.
Yuav ua li cas yog tias kev sib cuag ntawm kev pib relay tsis zoo?
Kev sib cuag tsis zoo ntawm kev sib txuas hauv Circuit Court kuj tuaj yeem ua rau kev sib cuag tsis zoo ntawm qhov pib relay. Yuav kom kho, lub hau ntawm lub relay yuav tsum tau qhib, thiab lub coil tshem tawm thiab welded, los yog muab nws cov contact piece hloov.
Nyob rau hauv luv luv, pib relays tuaj yeem kuaj los ntawm ntau txoj hauv kev, ntawm cov multimeters, voltmeters, thiab oscilloscopes yog cov cuab yeej ntsuas ntau. Thaum pom cov teeb meem cuam tshuam, lub Circuit Court yuav tsum tau kuaj xyuas thiab kho kom raws sijhawm. Yog tias koj xav yuav khoompib relays, koj tuaj yeem xaivQIANJI. Peb yuav muab kev daws teeb meem rau koj thiab tseem muab cov qauv rau kev sim.
