Lub kua dej twg xaiv rau lub tsheb?

Yog tias koj muaj ib lub tsheb twg, koj yuav tsum nkag siab zoo yog tias koj xav kom muaj kev nyab xeeb ntawm txoj kev, koj yuav tsum muab koj lub tsheb txoj kev braking nrog qhov zoo tshaj plaws kom nres tsheb.

Twg lub kua roj rau koj xaiv

Koj yuav tsum paub tias cov kua dej no yog lub hauv paus rau kev ua haujlwm kom nres thiab yog nyob ntawm seb ntau npaum li cas yog tias koj lub tsheb tuaj yeem nres nyob rau lub sijhawm thaum koj siv tus brake.

Txawm li cas los xij, qee zaum, tshwj xeeb tshaj yog rau cov neeg tsav tsheb uas tseem tsis tau muaj ntau txoj kev paub txog kev pabcuam hauv lub tsheb, nws nyuaj rau kev xaiv zoo tshaj plaws ntawm cov kua brake rau lub tsheb qauv uas lawv muaj.

Txhawm rau kom paub meej txog qhov no me ntsis, peb tau npaj cov khoom siv no hauv kev cia siab tias peb tuaj yeem muaj txiaj ntsig rau cov novice thiab cov tsav tsheb zoo.

Lub kua dej twg xaiv rau lub tsheb?

Ua ntej peb yuav tham txog cov hom ntawm cov kua hauv lub cev muaj nyob rau ntawm kev ua lag luam, koj yuav tsum paub ib lossis ob yam txog cov kua no.

Lub kua dej yog dab tsi?

Cov kua dej no tau yooj yim hu ua cov kua dej hydraulic, hauv kev coj ua txhais tau tias nws yog kua dej uas, dhau los ntawm nws qhov kev txav, txhawb kev ua haujlwm ntawm hydraulic systems.

Cov kua hauv lub cev muaj tshwj xeeb heev vim tias nws ua haujlwm nyob rau hauv kev ua haujlwm hnyav thiab yuav tsum tau ua tiav raws li qee yam xws li kub tsis kam tiv thaiv, tsis xeb, zoo viscosity, lwm yam

DOT raum hom dej

Tag nrho cov kua hauv lub cev tau muab faib raws li DOT (Lub Chaw Haujlwm Thauj Mus Los) tshwj xeeb, thiab qhov no yog qhov uas koj yuav tsum pib thaum xaiv lub kua dej rau koj lub tsheb.

Yeej muaj plaub yam ntawm cov kua hauv lub cev raws li cov lus qhia tshwj xeeb no. Qee tus ntawm lawv muaj cov yam ntxwv zoo sib xws, lwm tus yog cov sib txawv.

DOT3

Qhov hom nres kua dej hydraulic yog tsim los ntawm polyglycol. Nws qhov chaw kub npau npau yog li 140 degrees Celsius thiab nws cov taw tes qhuav yog 205 degrees. DOT 3 nqus 2% noo noo rau kwv yees li ib xyoos.

Hom nres kua hluav taws xob no yog siv rau hauv kev tsav tsheb tsis tshua zoo. (Rau lub tsheb qub, nruas tus pas thiab lwm cov tsheb txheem).

DOT4

Cov kua dej no kuj yog ua raws li polyglycol, zoo li yav dhau los version. DOT 4 muaj qhov kub npau npau ntawm 155 degrees Celsius thiab kub npau npau txog li 230 degrees. Zoo li DOT 3, cov kua dej no absorbs txog 2% noo noo thoob plaws hauv lub xyoo, tab sis muaj ib qho txiaj ntsig zoo dua nws, uas yog qhov kub siab dua, ua rau nws tsim nyog rau cov tsheb loj thiab kev ua haujlwm siab / lub zog SUVs.

DOT5.1

Qhov no yog hom kawg ntawm cov kua nres uas yog tsim los ntawm polyglycols. Piv nrog rau ob hom kua dej, DOT 5.1 muaj qhov kub siab tshaj plaws ntawm qhov kub thiab txias (ntub - 180 ° C, qhuav - 260 ° C). Zoo li lwm hom, nws absorbs txog 2% ntawm noo noo nyob rau hauv lub xyoo.

DOT 5.1 feem ntau yog siv rau cov tsheb nrog ABS cov tshuab lossis rau cov tsheb sib tw.

DOT5

Tsis zoo li txhua yam ntawm cov dej nres, DOT 5 yog raws li cov khoom siv silicone thiab hluavtaws sib xyaw. Cov kua muaj qhov ntub dej kub ntawm 180 ° C thiab qhov kub npau npau ntawm 260, ua rau nws yog cov kua hluavtaws zoo tshaj plaws. DOT 5 yog hydrophobic (tsis nqus dej noo) thiab tiv thaiv lub nres nres los ntawm corrosion. Hmoov tsis zoo, cov kua dej no tsis tuaj yeem sib xyaw nrog lwm hom, nws tus nqi yog ob peb zaug siab dua tus nqi ntawm glycol kua, uas ua rau nws muag nyuaj heev.

Qhov tseeb hais tias cov kua dej no tsuas siv tau rau hauv tsheb uas cov tuam ntxhab tau qhia meej meej txog kev siv nws kuj ua rau muaj kev txwv tsis zoo ntawm cov qauv tsheb thiab hom uas nws tuaj yeem siv. DOT 5 feem ntau siv nyob rau hauv cov tsheb loj niaj hnub, kev siv lub tshuab tshuaj tiv thaiv, thiab kev sib tw tsheb qauv.

Lub kua dej twg xaiv rau lub tsheb?
Peb los rau cov lus nug tseem ceeb tshaj plaws. Qhov tseeb yog tias cov tuam ntxhab qhia cov kua dej uas tsim nyog rau tus qauv thiab ua rau hauv lub tsheb, tab sis tsis txhob qhia lub hom yuav tsum tau siv.

Ntau yam cuam tshuam rau xaiv qhov tseeb ntawm cov kua nres rau koj lub tsheb, xws li koj lub tsheb qub, nws loj npaum li cas, txawm hais tias nws tau nruab nrog ABS lossis kev tswj hwm, uas qhov chaw tsim khoom pom zoo, thiab lwm yam.

Tseem, dab tsi tsim nyog xav txog thaum xaiv cov kua hauv dej rau koj lub tsheb.

Lub hom phiaj
Raws li tau hais, qee hom kev sib tw ntawm cov nres yog tsim rau cov ua haujlwm qis, lwm tus rau kev ua haujlwm siab, thiab tseem muaj lwm tus rau kev ua kis las lossis tsheb tub rog. Yog li no, thaum xaiv cov kua dej ua haujlwm rau koj cov qauv tsheb, xaiv ib qho uas tau teev tseg los ntawm cov khw.

Muaj pes tsawg leeg
Feem ntau cov dej nres yog 60-90% polyglycol, 5-30% lubricant thiab 2-3% additives. Polyglycol yog qhov tseem ceeb ntawm cov kua dej hydraulic, ua tsaug rau cov kua dej tuaj yeem ua haujlwm yam tsis muaj teeb meem hauv txhua qhov kub thiab txias.

Cov roj ntsha tau siv rau hauv cov kua hauv lub cev kom txo cov txhuam kev sib txhuam thiab txhim kho cov kua dej.

Cov quav ntxiv feem ntau muaj cov tshuaj tua kab mob antioxidant thiab tshuaj tiv thaiv corrosion. Lawv tshwm sim hauv cov kua dej thim vim tias lawv txo qhov oxidative degradation ntawm polyglycols, tiv thaiv thiab txo qis ntawm cov kua qaub zom cov kua dej, thiab tiv thaiv kom cov kua nyeem tuab.

Qhuav thiab ntub dej npau taw tes
Peb twb qhia qhov qhuav thiab ntub cov ntsiab lus ntawm txhua yam ntawm cov kua hauv lub cev, tab sis yuav ua rau nws pom tseeb dua ... Qhov kub npau npau hais txog qhov kub taw ntawm cov kua uas muaj qhov tshiab tag nrho (tsis ntxiv rau lub tsheb ntawm tus nres) thiab tsis muaj dej noo). Ntub dej rhaub yog hais txog qhov kub taw tes ntawm cov kua uas tau nqus ib feem pua ​​ntawm ya raws.

Dej nqus
Cov kua dej ua kua polyglycolic yog hygroscopic thiab tom qab ib pliag lawv pib nqus dej noo. Qhov kev ya raws ntau dua rau hauv lawv, lawv lub zog ntau zuj zus thiab, raws li, lawv cov hauj lwm tsawg.

Yog li no, thaum xaiv cov kua dej uas ua haujlwm rau koj lub tsheb, xyuam xim rau% ntawm qhov dej nqus ntawm lub qhov dej nres. Yuav tsum xaiv cov kua dej nrog qhov qis dua% li qhov no yuav txhais tau tias nws yuav zoo tiv thaiv koj lub tsheb txoj kev braking los ntawm xeb.

loj
Ntseeg nws los tsis, loj teeb meem. Peb tab tom tham txog qhov no vim tias muaj ntau lub hom phiaj ntawm cov tshuaj tua kab uas tuaj hauv qhov ntau thiab tsawg me me, uas txhais tau tias koj yuav tsum tau yuav ob peb lub hwj yog tias koj xav tau tso saum lossis hloov tag nrho ntawm cov kua dej. Thiab nws tsis zoo rau koj ntawm nyiaj txiag.

Cov tshuaj muaj nrov ntawm cov kua hauv lub cev

Tag nrho HBF 4
Lub hom khoom no nrov heev hauv peb lub teb chaws. Pom zoo rau kev ua haujlwm hydraulic ntawm txhua hom kev tsav tsheb siv DOT 4 cov kua hluavtaws.

Castrol 12614 DOT 4
Castrol yog lub npe nrov uas muab cov khoom lag luam zoo. Castrol DOT 4 yog cov kua nres ua los ntawm polyglycols. Cov kua dej tiv thaiv corrosion, tuaj yeem ua haujlwm ntawm qhov kub thiab txias thiab muaj cov kua dej ntau. Qhov tsis zoo ntawm Castrol DOT 4 yog tias nws tsis haum rau cov qauv tsheb, vim nws yog tsim los rau cov tsheb muaj zog dua thiab ua haujlwm zoo tshaj plaws hauv cov tsheb ua haujlwm siab.

Lub Caij Tsheb RBF600 DOT 4
Lub cev muaj zog nres cov kua hluav taws xob kom deb tshaj li cov qauv ntawm ntau DOT 3 thiab DOT 4. Nws muaj ntau qhov kev ntsuas uas cais cov kua dej no ntawm lwm tus. Lub cev muaj zog RBF600 DOT 4 yog nplua nuj los ntawm nitrogen, yog li nws muaj lub neej ntev dua thiab ntau dua qhov kev ua qias tuaj ua rau cov pa phem. Tsis tas li ntawd, nws muaj qhov kub siab heev, ob qho tib si ntub thiab qhuav, ua rau nws zoo tagnrho rau kev sib tw thiab tsheb siab. Qhov tsis zoo ntawm tus qauv no thiab lub npe ntawm cov kua hauv lub cev yog cov nqi siab dua thiab ua rau lub raj mis me dua uas nws tau txais.

Prestone AS401 - DOT 3
Zoo li DOT 3, Prestone muaj qhov kub qis dua li DOT 4 cov khoom, tab sis thaum muab piv rau lwm yam khoom hauv chav kawm, cov dej nres no muaj qhov tshwj xeeb zoo dua thiab zoo tshaj qhov kub ntawm qhov tsawg kawg nkaus. txiav txim los ntawm DOT. Yog tias koj lub tsheb khiav ntawm DOT 3 kua thiab koj xav txhim kho kev ua haujlwm ntawm koj cov dej nres, Prestone AS401 yog cov kua dej rau koj.

Cov hom thiab cov qauv ntawm cov kua hauv cov dej uas peb tau nthuav tawm rau koj sawv cev tsuas yog ib feem me me ntawm cov dej hydraulic uas muaj nyob rau ntawm kev ua lag luam, thiab koj tuaj yeem xaiv lwm hom khoom uas koj nyiam tshaj.

Hauv qhov no, dab tsi tseem ceeb tshaj plaws tsis yog hom twg koj nyiam, tab sis hom khoom dab tsi nres koj yuav tsum xaiv rau koj lub tsheb tshwj xeeb.
