I-DOT brake classification fluid nencazelo

I-Brake fluid yinto ekhethekile egcwalisa uhlelo lwamabhuleki wemoto futhi idlala indima ebalulekile ekusebenzeni kwayo. Idlulisa amandla kusuka ekucindezeleni isinqamu samabhuleki ngedrayivu ye-hydraulic iye ezinhlakeni zamabhuleki, ngenxa yokuthi imoto ibhulekiwe yamiswa. Ukugcina ubungako obudingekayo kanye nekhwalithi efanele ye-brake fluid ohlelweni kuyisihluthulelo sokushayela okuphephile.

Inhloso nezidingo zoketshezi lwamabhuleki

Inhloso enkulu ye-brake fluid ukudlulisa amandla asuka kusilinda oyinhloko wamabhuleki aya kumabhuleki asemasondweni.

Ukuzinza kwamabhuleki emoto nakho kuhlobene ngqo nekhwalithi ye-brake fluid. Kufanele ihlangabezane nazo zonke izidingo eziyisisekelo kubo. Ngokwengeziwe, kufanele unake umkhiqizi woketshezi.

Izidingo eziyisisekelo zamabhuleki uketshezi:

1. Iphuzu lokubilisa eliphakeme. Uma iphakama, kuncipha amathuba okwakhiwa kwamabhulebhu womoya ketshezi futhi, ngenxa yalokho, ukwehla kwamandla adluliswayo.
2. Iphoyinti lokushisa eliphansi.
3. Uketshezi kufanele kugcine ukuzinza kwezakhiwo zalo kuyo yonke impilo yalo yesevisi.
4. I-hygroscopicity ephansi (yezisekelo ze-glycol). Ukuba khona komswakama kuketshezi kungaholela ekugqobeni kwezingxenye zohlelo lwamabhuleki. Ngakho-ke, uketshezi kufanele lube nempahla efana ne-hygroscopicity encane. Ngamanye amagama, kufanele ibambe umswakama kancane ngangokunokwenzeka. Ngenxa yalokhu, kunezelwa kuwo ama-corrosion inhibitors, evikela izakhi zohlelo kusuka ekugcineni. Lokhu kusebenza kuketshezi olususelwa ku-glycol.
5. Izakhiwo zokuthambisa: ukunciphisa ukugqoka kwezingxenye zesistimu yamabhuleki.
6. Ayikho imiphumela eyingozi ezingxenyeni zenjoloba (O-izindandatho, amakhokho, njll.).

Brake uketshezi ukwakheka

Brake fluid iqukethe isisekelo nokungcola okuhlukahlukene (izithasiselo). Isisekelo sakha kufika ku-98% wokwakheka ketshezi futhi simelwe yi-polyglycol noma i-silicone. Ezimweni eziningi, i-polyglycol isetshenziswa.

Ama-Ethers asebenza njengezithasiselo, ezivimbela uketshezi oketshezi nge-oksijini yasemkhathini nangokushisa okuqinile. Futhi, izithasiselo zivikela izingxenye ekugqobeni futhi zinezinto zokuthambisa. Inhlanganisela yezakhi ze-brake fluid inquma izakhiwo zayo.

Ungaxuba kuphela iziphuzo uma ziqukethe isisekelo esifanayo. Uma kungenjalo, izici eziyisisekelo zokusebenza kwalokhu kuzokwehla, ezingaholela ekulimaleni kwezinto zohlelo lwamabhuleki.

Ukwahlukanisa uketshezi lwamabhuleki

Iziphuzo zamabhuleki zihlukaniswa ngezinhlobo eziningana. Ukwahlukaniswa kususelwa endaweni yokubilisa ketshezi kanye ne-viscosity yayo ye-kinematic ngokusho kwamazinga we-DOT (Department of Transportation). Lawa mazinga amukelwa nguMnyango Wezokuthutha wase-US.

I-viscosity ye-Kinematic ibhekene nekhono loketshezi lokujikeleza emgqeni wamabhuleki emazingeni okushisa asebenza ngokweqile (-40 kuye ku- + 100 degrees Celsius).

Indawo yokubilisa inesibopho sokuvimbela ukwakheka kwesikhiye somphunga esakha emazingeni aphezulu okushisa. Lezi zamuva zingaholela eqinisweni lokuthi iphedali yebhuleki ayenzi ngesikhathi esifanele. Isibonisi sethempelesha kuvamise ukucabangela iphuzu elibilayo "lokoma" (ngaphandle kokungcola kwamanzi) noketshezi "olunamanzi". Inani lamanzi kuluketshezi "olunamanzi" lufinyelela kuma-4%.

Kunezigaba ezine zoketshezi lwamabhuleki: DOT 3, DOT 4, DOT 5, DOT 5.1.

1. IDOT 3 ingamelana namazinga okushisa: ama-degree ayi-205 - oketshezi "olomile" kanye nama-degree ayi-140 - okukodwa "okuswakeme". Lezi ziketshezi zisetshenziswa ngaphansi kwezimo ezijwayelekile zokusebenza ezimotweni ezinezigubhu noma ama-disc brakes.
2. I-DOT 4 isetshenziswa ezimotweni ezinamabhuleki e-disc ezimotweni zasemadolobheni (imodi yokusheshisa-yokwehlisa). Indawo yokubilisa lapha kuzoba ngama-degree angama-230 - kuketshezi "olomile" kanye nama-degree ayi-155 - "olumanzi" Lolu ketshezi luvame kakhulu ezimotweni zesimanje.
3. I-DOT 5 isusicone futhi ayihambelani nolunye uketshezi. Indawo yokubilisa ketshezi elinjalo izoba ngama-260 no-180 degrees, ngokulandelana. Lolu ketshezi alonakalisi upende futhi alungenisi amanzi. Njengomthetho, awusebenzi ezimotweni zokukhiqiza. Imvamisa isetshenziswa ezimotweni ezikhethekile ezisebenza emazingeni okushisa adlulele wohlelo lwamabhuleki.
4. I-DOT 5.1 isetshenziswa ezimotweni zezemidlalo futhi inephuzu elibilayo elifanayo nele-DOT 5.

I-viscosity ye-kinematic yazo zonke izinhlobo zoketshezi ekushiseni kwama-degree angu-100 ayikho ngaphezu kwe-1,5 sq. mm / s., Futhi ngo -40 - kuyahluka. Ngohlobo lokuqala, leli nani lizoba ngu-1500 mm ^ 2 / s, okwesibili - 1800 mm ^ 2 / s, kowokugcina - 900 mm ^ 2 / s.

Ngokuphathelene nobuhle nobubi bohlobo ngalunye lwamanzi, kungahlukaniswa okulandelayo:

• ukwehla kwesigaba, izindleko ziphansi;
• ukwehla kwesigaba, kuyanda i-hygroscopicity;
• umthelela ezingxenyeni zenjoloba: I-DOT 3 idla izingxenye zenjoloba kanye noketshezi lwe-DOT 1 sezivele zihambisana ngokuphelele nazo.

Lapho ukhetha uketshezi lwamabhuleki, umnikazi wemoto kufanele alandele imiyalo yomkhiqizi.

Izici ukusebenza kanye esikhundleni ukubopha uketshezi

Kufanele kushintshwe kangaki uketshezi lwamabhuleki? Impilo yesevisi yoketshezi isethwe yi-automaker. I-brake fluid kufanele ishintshwe ngesikhathi. Akufanele ulinde kuze kube yilapho isimo sakhe sesiseduze nokubucayi.

Ungabona ngokusobala isimo sento ngokubukeka kwayo. I-brake fluid kufanele ihambisane, ibonakale futhi ingabi nasidumbu. Ngaphezu kwalokho, ezinsizeni zemoto, iphuzu loketshezi elibilayo lihlolwa ngezinkomba ezikhethekile.

Isikhathi esidingekayo sokuhlola isimo soketshezi senziwa kanye ngonyaka. I-Polyglycolic fluid idinga ukuguqulwa njalo eminyakeni emibili kuya kwemithathu, ne-silicone fluid - njalo eminyakeni eyishumi kuya kweyishumi nanhlanu. Lesi sakamuva sihlukaniswa ukuqina kwaso nokwakheka kwamakhemikhali, okumelana nezici zangaphandle.

isiphetho

Izidingo ezikhethekile zibekwa kwikhwalithi nokwakheka kuketshezi lwe-brake, ngoba ukusebenza okuthembekile kohlelo lwamabhuleki kuncike kulo. Kepha ngisho ne-brake fluid esezingeni eliphakeme ivame ukonakala ngokuhamba kwesikhathi. Ngakho-ke, kuyadingeka ukuthi uyihlole futhi uyishintshe ngesikhathi.
