Qhov tseem ceeb ntawmhorn relay
Lub horn relay ua kom lub horn thaum tus neeg tsav tsheb nias lub pob ua ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv tsheb. Qhov loj me me, tab sis nws lub luag haujlwm tseem ceeb heev hauv kev ua kom muaj kev nyab xeeb ntawm txoj kev los ntawm kev tsim cov suab nrov uas ceeb toom cov neeg tsav tsheb thiab cov neeg taug kev ntawm lub xub ntiag ntawm lwm lub tsheb. Lub horn relay no tuaj yeem hnav thiab ua tsis tiav nrog kev siv ntau ntxiv thaum lub sijhawm, yog li ua rau lub horn tsis ua haujlwm thiab ua rau tus neeg tsav tsheb tsis muaj zog hauv kev sib txuas lus ntawm txoj kev.
Kev sim horn relays yog qhov ua tau yooj yim dua, vim nws tsuas yog xav tau cov cuab yeej yooj yim thiab kev nkag siab zoo ntawm cov hluav taws xob ntawm lub tsheb. Cov kauj ruam luv luv thiab sib txawv yuav ua rau tus neeg tsav tsheb xaus rau lub sijhawm luv luv ntawm kev ua haujlwm ntawm lub horn relay. Ua li no, cov teeb meem tuaj yeem daws tau rau lub sijhawm kom muaj kev nyab xeeb ntawm kev tsav tsheb. Kev saib xyuas tsis tu ncua thiab kev sim ntawm horn relays tuaj yeem tiv thaiv kev ua tsis tiav ntawm cov cuab yeej thiab xyuas kom meej tias lub sijhawm tseem ceeb nws ua haujlwm.
Composition qauv ntawm horn relay
Relay muaj xws li electromagnet, hlau core, caij nplooj ntoos hlav tiv tauj, positioning ncej, horn, thiab hais txog. Lub horn yog qhov taw qhia tseem ceeb txhawm rau txheeb xyuas cov relay. Nws muaj ib tug hlau core thiab tooj liab coil. Thaum lub relay ua hauj lwm ib txwm, nws yuav ua rau lub suab ntawm lub horn; raws li lub suab uas nws tsim, ib tus tuaj yeem txiav txim siab txog kev ua haujlwm ntawm lub relay.
Yuav ua li cas kuaj horn relay

Ua hauj lwm suab nrhiav
Lub pob ntseg mloog ncaj qha: Txuas lub horn relay rau lub hwj huam mov raws li lub rooj tsav xwm ntsaws. Thaum xaim, peb tuaj yeem hnov cov "nias" suab tawm los ntawm cov relay. Thaum lub sij hawm tus txheej txheem no, peb muaj peev xwm intuitively txiav txim siab lub cev ua hauj lwm ntawm lub relay.
Relay Circuit Court nrhiav tau
Xyuas cov kev sib txuas ntawm lub horn relay rau tej yam tshwm sim ntawm kev puas tsuaj los yog corrosion.
Xyuas kom tseeb tias cov xov hlau txuas ruaj ntseg nrog cov relay thiab tsis muaj kev sib txuas xoob.
Tshem tawm cov kev xeb lossis av los ntawm kev sib txuas ntawm cov kab hluav taws xob kom ntseeg tau tias kev sib txuas hluav taws xob zoo.
Kuaj nrog ib tug multimeter
Txuas lub xov tooj liab ntawm lub multimeter mus rau lub hwj chim qaum ntawm lub relay, thiab av dub sojntsuam. Kev nyeem ntawv yuav tsum nyob ze lossis ncav cuag lub tsheb roj teeb voltage, feem ntau nyob ib ncig ntawm 12V
Cov lus qhia ntxaws kauj ruam:
Sab hauv Circuit Court ntawm lub tsheb horn relay yog qhia. Nyob nruab nrab ntawm 2 thiab 4 yog cov nquag qhib kev sib cuag ntawm cov relay, thaum nyob nruab nrab ntawm 1 thiab 3 yog cov electromagnetic coil thiab sib npaug ntawm cov relay.
Internal circuit daim duab ntawm lub tsheb horn relay
Xyuas qhov malfunction ntawm lub tsheb horn relay, raws li qhia nyob rau hauv daim duab.
Tig lub multimeter mus rau ohm ntau yam thiab siv ob qhov kev sojntsuam los ntsuas qhov kev tiv thaiv ntawm kev kuaj mob terminals 1 thiab 3, thiab ntawm terminals 2 thiab 4 ntawm lub tsheb horn relay. Vim hais tias kev sib cuag ntawm 1 thiab 3 yog ib txwm qhib, nws qhia tau hais tias qhib Circuit Court thiab tsis ua. Lub electromagnetic coil thiab sib npaug ntawm cov relay ntawm 2 thiab 4 yog conductive. Tsis muaj kev sib txuas ntawm 1 thiab 2, 1 thiab 4, 3 thiab 2, 3 thiab 4, yog li lawv tsis tau txuas ua ntej.
Kev tshuaj xyuas daim duab rau malfunctioning tsheb horn relay
Kev tshuaj xyuas ntawm kev ua haujlwm ntawm lub tsheb horn relay yog qhia hauv daim duab.
Txuas cov khoom siv hluav taws xob ntawm cov chaw kuaj mob 1 thiab 3 ntawm lub tsheb horn relay.
