Lub cav txias radiator yog ib feem tseem ceeb ntawm lub tsheb. Cov kab ke no txuas ntxiv tshem tawm cov cua sov ntau dhau ntawm lub cev muaj zog thiab dissipates nws mus rau ib puag ncig. Lub tshuab hluav taws xob ua haujlwm tau zoo tag nrho yog qhov lees paub ntawm qhov ntsuas kub zoo rau lub cav, uas nws tuaj yeem tsim nws lub zog tag nrho yam tsis muaj kev ua tsis tiav thiab teeb meem.

Zoo li txhua yam uas yog tsim los ntawm tus txiv neej, lub tshuab hluav taws xob muaj ntau yam ua haujlwm tsis zoo uas tuaj yeem tshwm sim thaum lub sijhawm tsis tsim nyog. Ib qho ntawm cov teeb meem tshwm sim yog lub radiator xau. Xav txog cov laj thawj vim li cas cov khoom siv hluav taws xob tuaj yeem xau, thiab nrhiav kev kho qhov teeb meem no li cas.

Kev puas tsuaj

Tsis muaj ntau yam uas ua rau muaj teeb meem nrog lub tshuab hluav taws xob. Tag nrho lawv tuaj yeem muab faib ua ob hom. Cov no yog cov neeg kho tshuab ua rau thiab ntuj hnav thiab tsim kua muag, uas ua rau muaj ntau yam kev puas tsuaj uas ua txhaum kev ncaj ncees thiab nruj ntawm lub cuab yeej. Txawm tias ib lub pob zeb me me uas ya tawm ntawm hauv qab lub log tuaj yeem ua rau tawg thiab tawg.radiator.

Tab sis qee zaum auto mechanics ntsib lwm yam - nws yog kev sib tsoo taub hau nrog lwm lub tsheb. Txawm tias me ntsis tshuab rau lub bumper yog txaus los ua kom tawg. Tsis tas li ntawd, mechanical vim li cas muaj xws li ntau yam kev kho uas yog ua los ntawm novice motorists. Qhov no feem ntau ua rau muaj kev puas tsuaj rau qhov tseem ceeb thiab cov khoom ntawm lub cuab yeej.

Cov txheej txheem Corrosion, nrog rau kev hnav thiab tsim kua muag, yog pawg thib ob ntawm cov laj thawj uas ua rau lub tshuab hluav taws xob xau. Nws yuav tsum nco ntsoov tias txawm tias me me khawb los yog chips tuaj yeem tig mus rau hauv qhov kub thiab txias ntawm kev ua haujlwm corrosion. Yog tias tsis tau them nyiaj rau qhov teeb meem no nyob rau lub sijhawm, tom qab ntawd raws li qhov tshwm sim ntawm kev puas tsuaj, lub qhov yuav tshwm sim los ntawm qhov uas cov dej txias yuav ntws tawm ntawm qhov system. Cov kab nrib pleb me me yog qhov nyuaj heev los kuaj xyuas. Tab sis yog tias koj poob rau kev lag luam tiag tiag, feem ntau txhua qhov kev puas tsuaj tseem tuaj yeem pom.

Cov no yog ob pawg ntawm cov laj thawj uas tuaj yeem ua rau muaj kev ntxhov siab thiab kev puas tsuaj rau cov khoom siv hluav taws xob thiab tom qab txias txias. Tsis tas li ntawd, kuj tseem muaj qee qhov teeb meem thaum lub sijhawm ua haujlwm, uas tuaj yeem ua rau kev ua haujlwm tsis zoo ntawm cov tshuaj tiv thaiv kab mob hauv lub cev.

Radiator leaking: qhov tshwm sim

Muab hais tias lub tshuab hluav taws xob nrog cov tshuaj tiv thaiv kab mob yog ib feem ntawm lub tshuab ua kom txias, nws yog qhov laj thawj tias thaum muaj kev ua haujlwm tsis zoo, lub cev muaj zog ua rau muaj kev pheej hmoo ntawm overheating. Qhov phem tshaj plaws, lub taub hau thiab lub tog raj kheej thaiv nws tus kheej yuav ua tau. Tab sis qhov notsis yog tag nrho. Kev khiav dej txias tuaj yeem nkag mus rau ntau qhov chaw, suav nrog roj hmab, uas nws tus kheej tsis zoo.

Yuav ua li cas txheeb xyuas qhov xau?

Yog tias lub cav pib overheat ntau zaus, thiab cov dej txias uas nyuam qhuav nchuav rau hauv lub tank sai sai tawm mus rau qhov chaw, nws yog qhov ceev kom kuaj xyuas lub tshuab hluav taws xob rau qhov. Yuav kom paub tias lub qhov nyob qhov twg, koj yuav tsum tau muab lub tshuab radiator thiab ua tib zoo tshuaj xyuas nws.

Tab sis tsis yog ib txwm ua tau kom pom lub qhov pom. Tom qab ntawd koj yuav tsum siv lwm txoj kev kuaj mob. Yog li, yuav ua li cas txheeb xyuas lub tshuab hluav taws xob kom pom qhov xau:

  1. Yuav ua li no, txhua qhov qhib ntawm lub cuab yeej raug kaw nrog nres.
  2. Yuav txo qis mus rau hauv lub thawv ntim dej kom haum.
  3. Tom ntej no, koj yuav tsum tau soj ntsuam - yog tias npuas tshwm, ces muaj qhov tawg ntawm cov chaw ntawm lub tshuab hluav taws xob.

Kev kuaj pom cov xau los ntawm cov kav dej lossis los ntawm cov khoom siv hluav taws xob nws tus kheej yuav tsis muaj teeb meem. Tab sis yog tias tsis muaj cov kua dej ntws tawm, thiab qhov kub ntawm cov tshuaj tiv thaiv kab mob los yog tshuaj tiv thaiv kab mob thaum lub sij hawm txav mus sai sai rau qhov tseem ceeb, ces nws yog qhov nyuaj dua los nrhiav qhov laj thawj. Feem ntau qhov xwm txheej no tshwm sim yog tias tsis muaj cov dej txias txaus lossis lub tshuab hluav taws xob tsis ua haujlwm zoo. Yog tias pom muaj ib qho dej txias hauv qab lub hood, nws tseem ceeb heev los kho lub radiator.

Yuav ua li cas kho qhov xau: xaiv txoj hauv kev raws li qhov xwm txheej

Muaj ntau txoj kev xaiv. Txoj hauv kev los txhim kho lub tshuab hluav taws xob xau yog nyob ntawm seb qhov tawg hauv nws thiab qhov twg pom qhov xau - hauvtxoj kev los yog chaw nres tsheb. Yog tias qhov tawg tau pom nyob rau hauv lub chaw nres tsheb thiab nws muaj peev xwm ua tiav kev kho nrog lub dismantling ntawm lub cuab yeej, ces koj tuaj yeem xaiv txoj kev kho uas siv cov vuam txias los yog soldering. Yog tias muaj teeb meem tshwm sim ntawm txoj kev, koj yuav tsum siv lub tshuab hluav taws xob xau.
