Vim li cas lub suab nrov nrov thaum pib lub cav ntawm qhov txias
Txheem
Ib tug feature ntawm cov tsos ntawm extraneous suab thaum pib lub cav nyob rau hauv feem ntau yog lub unavailable ntawm lub cav rau ib txwm ua hauj lwm nyob rau hauv cov nqe lus ntawm thermal tej yam kev mob, lub xub ntiag ntawm lubricant ntawm lub viscosity yuav tsum tau nyob rau hauv lub loaded units, raws li zoo raws li tsis ua hauj lwm ntawm cov khoom. hydraulics kom ncav cuag lub siab ua haujlwm.
Tab sis qhov teeb meem yog tias lub zog siv hluav taws xob, txawm tias ua haujlwm nrov dua li niaj zaus, kom txog rau thaum kawg ntawm kev ua kom sov, yuav tsum tsis txhob ua lub suab nrov uas cuam tshuam tus tswv hauv daim ntawv khob, rattles thiab crackles.
Lawv cov tsos, txawm tias tom qab ploj mus, qhia txog qhov pib ntawm kev ua haujlwm tsis zoo uas ua rau muaj kev ua tsis tiav.
Dab tsi tuaj yeem tsim lub rattle thiab creak thaum pib lub tsheb
Muaj ntau lub suab nrov raws nraim li muaj cov khoom siv tshuab hauv lub cav thiab cov khoom txuas. Yog li ntawd, nws ua rau kev nkag siab mus rau ib qho ntawm cov ntsiab lus, feem ntau manifested.
Oob khab
Txhawm rau hloov lub zog ntawm lub tshuab hluav taws xob mus rau lub crankshaft, lub retractor relay yuav tsum ua haujlwm nyob rau hauv lub oob khab, ces cov txhuam hniav yuav tsum xa mus rau lub collector, thiab lub freewheel (bendix) nrog nws tsav iav yuav tsum koom nrog flywheel crown.
Li no cov teeb meem muaj peev xwm:
- Nrog rau qhov tsis tshua muaj hluav taws xob ntawm lub tshuab hluav taws xob (tso tawm roj teeb) lossis oxidized wiring terminals, solenoid relay yog qhib thiab tso tawm tam sim ntawd, cov txheej txheem tshwm sim cyclically thiab manifests nws tus kheej nyob rau hauv daim ntawv ntawm ib tug crackle;
- lub bendix tuaj yeem plam, ua rau lub suab nrov hauv nws cov clutch;
- hnav tawm inputs ntawm lub bendix gears thiab lub crown yuav tsis muaj kev ntseeg siab, ua ib tug nrov tawg;
- suab nyob rau hauv daim ntawv ntawm ib tug rattle yuav raug tsim los ntawm ib tug hnav oob khab electric tsav thiab nws planetary gearbox.
Kev daws teeb meem nyob ntawm nws qhov chaw. Cov teeb meem feem ntau yog qhov poob qis, koj yuav tsum tau kuaj xyuas lub roj teeb thiab kev ntseeg siab ntawm txhua qhov kev sib cuag.
Lub hwj chim kauj
Lub hwj chim steering twj tso kua mis yuav tsum tsim kom muaj lub siab tseem ceeb, nyob ntawm qhov viscosity ntawm cov dej ua haujlwm thiab qhov xwm txheej ntawm cov khoom hauv lub xeev txias. Hnav thiab ua si yuav ua rau kev sib tsoo.
Ib tug yam ntxwv feature yuav yog ib tug nce nyob rau hauv lub suab thaum koj sim tig lub kauj. Yuav muaj kev thauj khoom ntxiv ntawm lub twj tso kua mis, uas yuav ntxiv ntim thiab hloov lub suab nrov.
Bearings
Tag nrho cov rotating qhov chaw ntawm attachments khiav ntawm bearings, uas nws thiaj li tsim lubrication thiab pib tawg.
Thaum nws sov, qhov kev sib hloov theem tawm thiab lub suab yuav ploj mus. Tab sis nws cov tsos mob thaum pib qhia txog qhov tshwm sim ntawm kev qaug zog tsis ua haujlwm, cov kab nrib pleb hauv cov khoom sib cais thiab kev tso tawm cov roj nplua nyeem.
Yog tias koj disassemble xws li cov kabmob, koj tuaj yeem pom qhov kev tshem tawm ntau ntxiv, cov kab ntawm pitting thiab rusty av es tsis txhob roj. Cov kabmob lossis cov khoom sib dhos yog hloov, piv txwv li, lub twj tso kua mis lossis cov menyuam.
Alternator siv thiab lub sij hawm system
Lub auxiliary siv loads cov lus qhia chais thiab lub pulley ntawm lub tshuab hluav taws xob nws tus kheej nrog nws nruj. Qhov nruj dua, qhov ceev ntawm cov bearings yuav hnav, nrog rau txoj siv sia nws tus kheej. Tus tsav yuav ua hauj lwm nrog lub siab zaus jerks, uas yuav manifest nws tus kheej acoustic lub zog, qhov kub thiab txias.
Kev nruj thiab kev taw qhia rollers, siv, bearings ntawm lub tshuab hluav taws xob rotor, nws cov clutch overrunning yuav raug hloov. Yog tias koj ua kev saib xyuas hauv ib lub sijhawm teem tseg thiab txhim kho cov khoom zoo, ces qhov no tsis suav nrog.
Nyob rau hauv ntau lub tshuab, camshafts yog tsav los ntawm ib tug toothed siv. Nws yog heev txhim khu kev qha, tab sis durability yog txwv.
Lub sijhawm teem sijhawm hloov ntawm txoj siv, cov menyuam thiab lub twj tso kua mis pom zoo kwv yees li ib zaug txhua 60 txhiab kilometers. Nws tsis tsim nyog ntseeg cov tuam txhab lag luam uas cog lus ib mais ntawm 120 txhiab lossis ntau dua, qhov no tsis zoo li, tab sis txoj siv tawg yuav ua rau kev kho lub cev loj.
Qhov chaw ntawm lub valve mechanism tuaj yeem yog qhov chaw ntawm lub khob. Lub camshaft theem shifters hnav tawm, valve thermal clearances ploj mus los yog hydraulic compensators tsis tuav lub siab qhov twg lawv tau ntsia.
Ntau yam nyob ntawm qhov zoo ntawm cov roj thiab nws cov kev hloov raws sij hawm. Tsis yog 15-20 txhiab kilometers, raws li cov lus qhia, tab sis 7,5, siab tshaj 10 txhiab. Tsis tas li ntawd, cov roj degrades zoo heev, thiab cov lim yuav txhaws nrog cov khoom hnav.
Chain tensioner
Nyob rau hauv niaj hnub xyaw, manufacturers siv zog txo tus nqi ntawm cov txij nkawm, yog li lub sij hawm saw drives yog nruab nrog hydraulic tensioners. Cov khoom no nyob rau hauv lawv tus kheej yog tsis ntseeg kiag li, ib qho ntxiv, raws li cov saw hnav tawm (lawv tsis ncab, raws li ntau tus neeg xav, tab sis hnav tawm), cov khoom siv ntawm cov regulator yog tag.
Cov saw tsis muaj zog pib khob, tawg tag nrho nws qhov chaw ib puag ncig, tensioners, dampers, casings thiab hydraulic compensator nws tus kheej. Hloov cov khoom siv yog xav tau tam sim ntawd, tag nrho cov tsav yuav tawg sai sai, thiab lub cev muaj zog yuav xav tau kev kho dua tshiab.
Yuav ua li cas los txiav txim qhov chaw ntawm lub cod nyob rau hauv lub cav
Hauv kev kuaj mob, muaj cov xwm txheej zoo thaum tus tswv, los ntawm qhov xwm txheej ntawm lub suab thiab lub sijhawm ntawm nws qhov tshwm sim, tuaj yeem ntseeg tau hais tias qhov yuav tsum tau kho. Tab sis qee zaum koj yuav tsum tau mloog ntau dua rau lub cav. Acoustic thiab electronic stethoscopes yog siv.
Valve clearances tau pom meej los ntawm sab ntawm lub hau saum toj kawg nkaus. Cov no yog sonorous knocks nrog ib zaus hauv qab qhov ceev ntawm kev sib hloov ntawm lub crankshaft. Hydraulic lifters feem ntau pib khob thaum pib, maj mam nres thaum lawv sau cov roj ua kom sov. Lub khob ntawm camshafts nyob rau hauv lawv lub txaj yog ntau booming.
Lub sijhawm tsav tau hnov thaum kuaj xyuas lub hau npog ntawm lub cav. Thaum pib ntawm cov menyuam hnav manifests nws tus kheej nyob rau hauv daim ntawv ntawm howling thiab whistling, tom qab tsis quav ntsej txog qhov yuav tsum tau hloov, nws hloov mus rau hauv ib tug rattle, ces lawv tag nrho puas tsuaj nrog rau kev puas tsuaj loj.
Kev sib txuas bearings yog qhov yooj yim rau kev kuaj xyuas tom qab tshem tawm txoj siv. Lawv tig los ntawm tes nrog cov ntawv ceeb toom ntawm cov pob deformed, ua rau lub suab nrov txawm tias tsis muaj kev thauj khoom, thiab hauv lub twj tso kua mis qhov sib txawv yuav nce ntau heev uas nws yuav tsis tuav cov kua nrog nws lub thawv ntim khoom, drips yuav ua rau dej nyab ntawm qhov chaw.
Cov hlua yuav tsum tsis txhob tawg, tev los yog tawg. Tab sis lawv hloov raws li cov cai, txawm tias lawv zoo meej. Kev puas tsuaj sab hauv yuav ua rau muaj kev tawg sai sai.
Qhov yuav tshwm sim
Qhov hnyav ntawm qhov tshwm sim nyob ntawm qhov tshwj xeeb lub cev muaj zog. Raws li kev tsim qauv, lawv tuaj yeem tiv taus ntau dua lossis tsawg dua ntawm kev sib tsoo ntawm tus kheej, tab sis nyob rau hauv txhua rooj plaub, qhov no yuav txhais tau tias yog lub tsheb thauj khoom lossis tsheb thauj khoom.
Yog hais tias lub twj tso kua mis tsis ua hauj lwm, lub cav yuav overheat nyob rau hauv load thiab tau qhab nia los yog ib tug wedge ntawm piston pawg. Qhov no yog ib tug loj overhaul, tus nqi ntawm uas yog piv rau tus nqi ntawm ib daim ntawv cog lus lub cev muaj zog.
Raws li cov teeb meem nrog lub sij hawm tsav, motors feem ntau muab faib ua plug-in thiab plug-in.
- Thawj zaug, yog tias lub synchronization ntawm lub camshafts tsis ua haujlwm, lub rooj sib tham ntawm cov li qub nrog cov pistons yog qhov kev zam, tom qab ntawd koj yuav tsum tshem tawm thiab txheeb xyuas lub taub hau thaiv.
- Qhov thib ob yuav tsuas nres, txhua yam yuav raug txwv kom hloov lub sijhawm tsav.
Tab sis lub cev muaj zog niaj hnub no tej zaum tsis muaj kev tiv thaiv los ntawm lub rooj sib tham zoo li no. Kev lag luam yuav tsum muaj qhov sib piv siab compression, tsuas yog tsis muaj chaw rau lub valve daig hauv lub combustion chamber.
Yog li qhov tseem ceeb ntawm kev saib xyuas raws sijhawm nrog kev hloov pauv tsis tu ncua ntawm cov khoom siv - siv, cov menyuam, chains thiab tsis siv neeg tensioners.
