Yuav Ua Li Cas Ntsuas Trailer Nres nrog Multimeter (Peb-kauj Qhia)

Faulty los yog hnav trailer nres hlau nplaum tuaj yeem ua teeb meem loj nrog kev nres lub trailer tam sim. Qee qhov teeb meem tuaj yeem pom tsuas yog los ntawm saib koj cov hlau nplaum nres, tab sis qee zaum kuj muaj qee yam teeb meem hluav taws xob uas cuam tshuam rau koj lub tsheb nres.

Cov hlau nplaum tsis zoo tuaj yeem ua rau cov brakes slack lossis surge los yog ua rau cov brakes rub mus rau ib sab. Qhov no yog qhov laj thawj zoo txaus kom nkag siab tias koj lub braking system ua haujlwm li cas thiab yuav kho li cas yog tias xav tau tshwm sim. Cov kauj ruam tseem ceeb tshaj plaws hauv kev nkag siab yuav ua li cas trailer brakes ua haujlwm yog kawm yuav ua li cas kuaj trailer brakes nrog multimeter.

Feem ntau, yog tias koj xav sim koj lub tsheb nres tsheb nrog lub multimeter, koj yuav tsum tau:

(1) Tshem tawm cov hlau nplaum nres

(2) Muab lub nplhaib hlau nplaum rau ntawm qhov chaw nres tsheb tsis zoo.

(3) Txuas cov xov hlau zoo thiab tsis zoo.

Hauv qab no kuv yuav piav qhia peb kauj ruam no kom ntxaws.

Nkag siab txog kev ua haujlwm ntawm lub braking system

Muaj ob lub ntsiab ntawm trailer braking system: impulse trailer brakes thiab hluav taws xob trailer nres. Ua ntej koj mus kuaj, koj yuav tsum paub seb hom braking system koj lub tsheb muaj. Hauv qab no kuv yuav tham txog ob hom braking systems. (1)

• Thawj hom yog trailer impulse brakes, uas muaj cov impulse clutch mounted ntawm tus nplaig trailer. Nyob rau hauv hom trailer nres, lub braking yog tsis siv neeg, uas txhais tau hais tias tsis tas yuav muaj kev sib txuas hluav taws xob ntawm lub tsheb laij teb thiab lub trailer, tshwj tsis yog lub teeb taws. Sab hauv muaj kev sib txuas nrog lub ntsiab hydraulic lub tog raj kheej. Lub zog rau pem hauv ntej ntawm lub trailer ua rau ntawm kev tiv thaiv kev tiv thaiv clutch thaum twg lub tsheb laij teb siv cov brakes. Qhov no ua rau lub tsheb txav rov qab thiab muab kev kho mob ntawm tus tswv lub tog raj kheej piston pas nrig.
• Qhov thib ob hom nres yog lub trailer lub fais brakes, uas yog actuated los ntawm ib tug hluav taws xob kev twb kev txuas mus rau lub nres pedal los yog ib tug sib txawv inertia hloov mounted rau lub trailer lub dashboard. Thaum twg lub trailer hluav taws xob brakes raug siv, ib qho hluav taws xob tam sim no proportional rau tus nqi deceleration energizes ib tug hlau nplaum nyob rau hauv txhua tus nres. Cov hlau nplaum no ua rau lub zog uas, thaum qhib, siv cov brakes. Hom maub los no tuaj yeem teeb tsa rau qhov sib txawv trailer loads.

Yuav ua li cas kuaj trailer brakes nrog multimeter

Yog tias koj xav ntsuas koj lub tsheb nres tsheb nrog lub multimeter, koj yuav tsum ua raws li 3 cov kauj ruam tshwj xeeb, uas yog:

1. Thawj kauj ruam yog tshem cov hlau nplaum nres ntawm lub trailer.
2. Cov kauj ruam thib ob yog muab lub hauv paus ntawm tus nres hlau nplaum rau qhov tsis zoo ntawm lub roj teeb.
3. Cov kauj ruam kawg yog txhawm rau txuas qhov zoo thiab qhov tsis zoo ntawm cov multimeter mus rau lub roj teeb. Koj yuav tsum txuas ib lub multimeter mus rau lub xiav xaim mus rau sab nraum qab ntawm tus nres nres thiab yog tias koj pom ib qho tam sim no ntawm lub multimeter ces tus nres hlau nplaum tuag thiab yuav tsum tau hloov.

Kuv xav kom koj siv lub roj teeb 12 volt thaum kuaj xyuas lub kaw lus nres thiab koj yuav tsum txuas lub xov tooj xiav uas tswj cov brakes mus rau multimeter thiab muab tso rau hauv qhov chaw ammeter. Koj yuav tsum tau txais qhov siab tshaj plaws amp nyeem hauv qab no.

Nres txoj kab uas hla 10-12

• 5-8.2 hli nrog 2 brakes
• 0-16.3 hli nrog 4 brakes
• 6-24.5 hli siv nrog 6 brakes

Nres txoj kab uas hla 7

• 3-6.8 hli nrog 2 brakes
• 6-13.7 hli nrog 4 brakes
• 0-20.6 hli siv nrog 6 brakes

Kuv kuj qhia koj kom siv lub ohmmeter feature ntawm koj lub multimeter los xyuas qhov tsis kam ntawm koj cov hlau nplaum nres.

Muaj qee qhov ntau yam uas koj yuav tsum pom ntawm koj cov hlau nplaum nres thiab qhov ntau yuav tsum nyob nruab nrab ntawm 3 ohms thiab 4 ohms nyob ntawm qhov loj ntawm koj cov hlau nplaum nres, yog tias qhov tshwm sim tsis zoo li no ces cov hlau nplaum nres yuav puas thiab yuav tsum tau. hloov. (2)

Thaum kuaj xyuas koj lub tsheb nres tsheb, muaj teeb meem hluav taws xob uas tuaj yeem cuam tshuam koj lub brakes ua haujlwm li cas, thiab koj tuaj yeem ua qhov kev tshuaj xyuas kom pom qhov twg qhov txhaum nyob hauv koj lub nres nres.

Kev kuaj pom pom yuav tsum muaj peb kauj ruam los txiav txim seb puas muaj teeb meem.

1. Thawj kauj ruam yog xyuas lub tsheb nres tsheb nres rau cov paib ntawm txhua yam kauj. Yog tias koj pom nws, nws txhais tau hais tias nws hnav tawm thiab yuav tsum tau hloov sai sai.
2. Cov kauj ruam thib ob yog coj tus pas ntsuas uas koj yuav nteg hla saum cov hlau nplaum. Cov ntug no yuav tsum tau sib npaug rau ntawm ntug ncaj txhua txoj kev, thiab yog tias koj pom muaj kev hloov pauv lossis khawb hauv qhov chaw ntawm cov hlau nplaum, qhov no yog qhov qhia txog kev coj txawv txawv thiab yuav tsum tau hloov tam sim ntawd.
3. Cov kauj ruam kawg yog xyuas cov hlau nplaum rau roj lossis roj seem.

Cov tsos mob ntawm qhov tsis zoo trailer nres

Muaj qee yam teeb meem uas koj yuav tsum paub txog yog tias koj tsis nyiam kuaj trailer nres. Cov teeb meem no qhia tau tias koj yeej muaj teeb meem nres thiab koj yuav tsum tau kuaj xyuas koj lub trailer tam sim ntawd kom paub meej. Nov yog qee qhov teeb meem no:

• Ib qho teeb meem zoo li no yog qhov tsis muaj zog pem hauv ntej hluav taws xob nres, tshwj xeeb tshaj yog tias koj muaj hluav taws xob nres ntawm plaub lub log ntawm koj lub trailer. Nyob rau hauv ib qho xwm txheej uas txhua yam ua haujlwm zoo kawg nkaus, qhov puag ncig ntawm tus brake actuating lever yuav tsum taw tes rau pem hauv ntej kom cov trailer brakes ua haujlwm zoo.
• Lwm qhov teeb meem tshwm sim thaum koj pom tias koj lub trailer yog qee yam rub mus rau sab thaum koj siv lub brakes. Qhov no qhia tau hais tias koj trailer lub braking tsis tshuav.
• Lwm qhov teeb meem loj yog tias koj pom tias koj lub tsheb nres tsheb nres rau qhov kawg ntawm qhov nres. Thaum koj tuaj txog ntawm qhov nres thiab koj lub nres nres, qhov teeb meem yog nrog lub nres nres nres. Feem ntau, qhov kev tiv thaiv ntawm cov brakes yog siab dhau lawm, uas yuav ua rau rupture thiab hnav ntawm lub brakes.

Koj tuaj yeem tshawb xyuas ntawm no yuav ua li cas ntsuas lub teeb trailer nrog lub multimeter.

Summing txog

Nws yuav tsum nco ntsoov nco ntsoov tias lub tsheb nres tsheb yuav tsum tau saib xyuas tsis tu ncua vim tias cov khoom hnyav nqa los ntawm cov tsheb no, yog li kuv xav qhia koj kom saib xyuas koj lub tsheb nres tsheb kom tsis txhob muaj kev sib tsoo lossis kev sib tsoo ntawm txoj kev vim kev nres tsheb tsis raug. tshuab.

Teeb meem nrog luv luv Circuit Court nyob rau hauv cov xaim kuj ua rau muaj teeb meem loj. Cov xov hlau hnav lossis puas tuaj yeem tshwm sim los ntawm kev tso cov hlau hauv lub qag nws tus kheej.

Yog tias koj pom cov lus ntawm lub tshuab nres nres nres hais tias "tso zis luv", koj yuav tsum pib nrhiav cov teeb meem hauv koj lub qag. Koj yuav tsum tau ceev faj heev thaum ua haujlwm nrog cov xov hlau thiab hluav taws xob tiv thaiv hluav taws xob.

Lwm cov kev qhia muaj txiaj ntsig uas koj tuaj yeem saib lossis bookmark tau teev tseg hauv qab no;

• Yuav ua li cas kuaj lub roj teeb nrog lub multimeter
• Yuav ua li cas ntsuas amps nrog multimeter
• Yuav Siv Cen-Tech Digital Multimeter los kuaj qhov voltage
