Maitiro ekuyedza Relay neMultimeter (Nhanho neNhanho Gwaro)

Relays ndechimwe chezvinhu zvakakosha zvemagetsi mumotokari, maotomatiki masisitimu epamba uye mamwe maapplication uko kunodiwa kukurumidza kuchinjika kwemaseketi emagetsi epamusoro. Nekudaro, senge electromechanical zvishandiso, relays inopfeka uye kubvaruka uye inogona kukundikana chero nguva. Nekudaro, zvakakosha kuti uedze marelay ako nguva nenguva kuti uone kuti anoita nepaanogona napo.

Imwe yedzakasiyana relay bvunzo nzira idhijitari multimeter. Rega ndikufambise nematanho ekutanga kuyedza relay ine multimeter.

About relay

A relay inyanzvi yemagetsi yekudzora ine hurongwa hwekugadzirisa (input circuit) uye inodzorwa system (output circuit), iyo inowanzowanikwa mumatunhu ekutonga. Inoshanda sedunhu regulator, chengetedzo yedunhu uye inoshandura. Iyo relay inoratidza kukurumidza kupindura, kuita kwakagadzikana, hupenyu hwesevhisi hurefu uye saizi diki. (1)

Relays anowanzo shandiswa kudzora yakakwira yazvino dunhu kubva kune yakaderera ikozvino dunhu. Vari mumotokari dzinenge dzose. Relays inoshanda sema switch, ichibvumira yakaderera amperage circuit kuvhura kana kudzima yakakwira amperage circuit. Pamusoro pezvo, iyo relay inogona zvakare kudzora akawanda masisitimu panguva imwe chete, sekubatidza marambi emusoro kana ma wiper akabatidzwa, kana kuwedzera antenna kana redhiyo yakabatidzwa.

Zvaunoda Paunenge Uchiyedza Relay

Kuedza relay yemotokari yako inzira yakapusa isingade kushandiswa kwekiti yakazara. Kuti utange kuyedza relay, iwe uchada zvinotevera zvinhu:

Zvombo: 

• High impedance test light
• An ohmmeter, inowanzonzi digital multimeter (DMM).
• Automotive Service Manual (inosarudza asi inokurudzirwa zvakanyanya)

Spare zvikamu:            

• Yakakodzera Relay Replacement
• jumper wire

Relay Test Matanho

Danho 1: Tsvaga Relay 

Zvichienderana nezvainodzora, unogona kuwana relay pasi pe dash kana mune injini bay. Tarisa chitsauko chemagetsi chebhuku rako rebasa uye dhayagiramu yewaya kana usina chokwadi chekuiswa.

Danho 2: Tarisa uye uchenese zvibatanidza

Kana wangowana relay, bvisa. Wobva wachenesa uye ongorora majoini apo iyi relay yakadzimwa. Kutsiva iyo huru relay neinotsiva yakakodzera ndiyo inokurumidza uye iri nyore nzira yekuiedza.

Nhanho 3: Tora multimeter

Gadzirisa yako multimeter kune kuramba kuyerwa maitiro. Wobva wayera kupikisa nekubata macoil contacts. Iyo yakajairika coil ine kuramba kwe40 ohms kusvika 120 ohms. A bad solenoid coil winding inoratidza kuti relay iri kunze kwerenji kana kuvhurika uye yave nguva yekuitsiva. Wobva wachengeta iyo multimeter mukupokana kana kuenderera maitiro. Mushure maizvozvi, batanidza kushandura mazita kune zvinotungamirira. Inofanirwa kuratidza yakavhurika kana OL kana iri yakajairika yakavhurika relay.

Nhanho 4: Batidza iyo electromagnet coil 

Nebhatiri re9-12V pane vanobatika, shandisa simba kune iyi magineti coil. Kana iyo coil ichipa simba uye ichivhara switch, iyo relay inofanirwa kuita inonzwika kudzvanya. Pane 4-pini relay, polarity haina kukosha, asi pane diode relays yakakosha.

Danho rechishanu: Batanidza mwenje wekuedza 

Batanidza bhatiri riri positive kune imwe yema switch terminals apo coil ichiri kushanda. Wobva wabatanidza mwenje wekuyedza pakati pevhu uye switch terminal. Rambi rekutonga rinofanira kupedza magetsi nekupenya. Zvadaro bvisa jumper yakanaka kubva mubhatiri. Rambi rekudzora rinofanira kubuda mushure memasekondi mashoma.

Nhanho 6: Kutarisa Voltage Relay

Pakuchinja, tarisa relay voltage. Mapoinzi akashata ekusangana anogona kutungamira mukurasikirwa kwevoltage. Bvisa mwenje wekuyedza uye shandura iyo multimeter kuita DC voltage. Wobva wabatanidza waya kune zvibatanidza mwenje wekuyedza kana shandura maconta. Kuverenga kunofanirwa kuenderana nebhatiri voltage.

Danho 7: Tarisa switch

Tarisa kupikisa kwakaringana muchinja. Iyo yakanaka jumper inofanira kubviswa uye iyo solenoid coil inofanira kusimbiswa. Wobva wayera kupokana nepakati pemabatiro ekuchinja ane multimeter yakaiswa kune ohms. Kazhinji, relay yakavhurika inofanirwa kuyera pedyo ne zero kuramba kana yabatidzwa, nepo relay inowanzovharika inofanirwa kuyera yakavhurika kana OL kana yakabatidzwa.

Relay Testing Pro Mazano

Paunenge uchishanda nerelays, zvinokurudzirwa kuyeuka zvinotevera:

Dzivisa kusanganisa uye kuenzanisa 

Kana iwe uine relay yakaipa inoda kutsiviwa, haisi zano rakanaka kusanganisa uye kuenzanisa relay kubva kune zvimwe zvikamu zvemotokari kana gaba remarara mugaraji rako. Izvi zvinogona kukonzeresa kupfupika kwedunhu kana kuvhiya kwemagetsi kunokuvadza hurongwa hwemagetsi emotokari yako. (2)

Bata zvakanaka

Zvinonyanya kukosha kungwarira kuti usadonhedze relay. Kana zvikamu zvemukati zve relay zvakaparadzwa, wiring inogona kupisa kana kunyunguduka. Uyewo rega kupindira nekushanda kwerelay.

Ramba kure nemagasi anobvira 

Usashandise relay kana chero chinhu chinoda magetsi munzvimbo dzine magasi anoputika kana anopisa sepeturu kana mamwe mafuta.

Verenga mabhuku ekugadzirisa

Tarisa bhuku rebasa remotokari yako (kwete bhuku remuridzi wako) kuti uone uye unzwisise wiring uye relay system, kunyangwe iwe watove mugadziri ane ruzivo rwegaraji.

Ronga maturusi ako 

Gadzirira maturusi ese anodiwa pachine nguva uye isa zvese munzvimbo yayo. Izvi zvichakuchengetera nguva yakakosha uye zvinokutendera kuti utarise pane ikozvino basa pasina kutsvaga zvishandiso panguva yekuita.

Inowanzobvunzwa Mibvunzo 

Inodhura marii kutsiva relay?

Relay inogona kuita chero kubva pamadhora mashanu kusvika kumazana akati wandei emadhora, zvichienderana nezvainotonga. Inotevera ndeye ohmmeters, iyo inodhura isingasviki $5 uye inouya mumhando dzakasiyana-siyana uye hukuru. Chechipiri, mwenje wekuedza wepamusoro wakadhura zvishoma, avhareji yemadhora makumi maviri kusvika makumi mana. Pakupedzisira, jumpers inodhura, kubva pa $ 20 kusvika ku $ 20 zvichienderana nehurefu hwetambo.

Chii chinoitika kana ndikafuratira dambudziko rinogona kuitika?

Kuregeredza relay yakakundikana kana kuisa chero yekare relay inokwana inogona kukonzera matambudziko akakomba. Kana relay ikatadza kana kuiswa zvisirizvo, inogona kupisa waya uye pamwe kutanga moto.

Handina ohmmeter kana chiedza chekuedza. Ndichiri kutarisa relay?

Aihwa. Iwe unongova nesarudzo mbiri chete kana uine chokwadi chekuti relay yako idambudziko, uye zvese zvinoda kushandiswa kweohmmeter, mwenje wekuyedza, nezvimwe. Chekutanga, chenjera uye tsiva iyo huru relay nematurusi anodiwa. Chechipiri, kana usina midziyo yekuiedza, unogona kuhaya makanika kuti atarise uye agadzirise relay yako.

Iwe unogona zvakare kutarisa mamwe madhairekitori ekuedza emultimeter pazasi;

• Nzira yekuedza capacitor ne multimeter
• Maitiro ekushandisa multimeter kutarisa voltage yewaya mhenyu
• Nzira yekuedza pasi ne multimeter
