Hoʻonohonoho a me ka wehewehe o ka wili DOT

ʻO ka wai brake kahi mea kūikawā e hoʻopihapiha i ka ʻōnaehana braking o kahi kaʻa a hana nui i kāna hana. Hoʻolilo ia i ka ikaika mai ke kaomi ʻana i ka pedal rem ma o ka hoʻokele neʻe i nā ʻano hana braking, ma muli o ka uila o ke kaʻa a kū. ʻO ka mālama ʻana i ka nui i makemake ʻia a me ke kūpono kūpono o ka wai hoʻowali i ka ʻōnaehana ke kī i ka hoʻokele palekana.

ʻO ke kumu a me nā koi no nā wai wili

ʻO ke kumu nui o ka wai hoʻoheheʻe e hoʻoili i ka mana mai ka paukū palima nui i nā paleki ma nā huila.

ʻO ke kūpaʻa paʻa o ke kaʻa e pili pono hoʻi i ka maikaʻi o ka wai wili. Pono e hoʻokō i nā koi maʻamau no lākou. Hoʻopili, pono ʻoe e hoʻolohe i ka mea hana i ka wai.

Nā koi maʻamau no nā wai wili:

1. Kahi kukuna kiʻekiʻe. ʻO ke kiʻekiʻe ʻo ia, ʻo ka liʻiliʻi o ka likelihood o ka hoʻokumu ʻia ʻana o nā huʻa ea i loko o ka wai a, ma muli o ka hopena, kahi emi o ka ikaika i lawe ʻia.
2. Kukui pae haʻahaʻa.
3. Pono ka wai e mālama i ke kūpaʻa o kāna mau waiwai i kona ola holoʻokoʻa holoʻokoʻa.
4. ʻO ka haʻahaʻa haʻahaʻa (no nā kumu glycol). ʻO ke kū ʻana o ka wai i loko o ka wai e hiki ai ke alakaʻi i ka pala o nā ʻāpana o ka ʻōnaehana. No laila, pono e loaʻa ka wai i kahi waiwai e like me ka hygroscopicity liʻiliʻi. I nā huaʻōlelo ʻē aʻe, pono e omo ia i ka ona e like me ka hiki. No kēia, hoʻohui ʻia nā mea kūpikipiki iā ia, e pale ana i nā mea o ka ʻōnaehana mai ka hope. Pili kēia i nā wai a pili i ka glycol.
5. Lubricating waiwai: e hoʻēmi i ka ʻaukā o nā ʻāpana o ka ʻōnaehana.
6. ʻAʻohe hopena ʻino ma nā ʻāpana kāpili (O-ring, cuffs, a pēlā aku.).

Pākuʻi wai hoʻoheheʻe

ʻO ka wai brake kahi kumu a me nā impurities (nā mea hoʻohui). Hana ke kumu i 98% o ka hoʻohui ʻana o ka wai a hōʻike ʻia e polyglycol a i ʻole silicone. I ka hapanui o nā hihia, hoʻohana ʻia ʻo polyglycol.

Hana ʻo Ethers i mea hoʻohui, kahi e pale ai i ka hoʻohaʻahaʻa o ka wai me ka oxygen lewa a me ka hoʻomehana wela. Eia kekahi, pale nā ​​mea hoʻohui i nā ʻāpana mai ka popopo a loaʻa nā waiwai lubricating. ʻO ka hui pū ʻana o nā ʻāpana o ka wai wili e hoʻoholo ai i kāna mau waiwai.

Hiki iā ʻoe ke hoʻopili wale i nā wai inā pili lākou i ka waihona like. Inā ʻole, e hōʻino nā hiʻohiʻona hana maʻamau o ka mea, i hiki ai ke alakaʻi i ka hōʻino ʻana i nā mea o ka ʻōnaehana paʻa.

Hoʻohui ʻia o nā wai wili

Hoʻonohonoho ʻia nā wai brake i nā ʻano like ʻole. Hoʻokumu ʻia ka hoʻonohonoho ʻana ma ka wahi paila o ka wai a me kona viscosity kinematic e like me nā kūlana DOT (Department of Transportation). Lawe ʻia kēia mau kūlana e ka US Department of Transportation.

No Kinematic viscosity ke kuleana o ka wai e hoʻopuni i ka laina wili i ke ana wela o ka hana (-40 a + 100 kekelē Celsius).

ʻO ke kiko paila ke kuleana no ka pale ʻana i ka hoʻokumu ʻana o ka laka mahu e hana ʻia i nā mahana wela. Hiki i ka mea hope ke alakaʻi i ka ʻoiaʻiʻo ʻaʻole hana ka pedal rem i ka manawa kūpono. Lawe ka mea kuhikuhi wela i ka helu o ka paila o ka "maloʻo" (me ka ʻole o nā wai haumia) a me ka wai "mākū". ʻO ka mahele o ka wai i loko o ka wai "moisturified" a hiki i 4%.

ʻEhā papa o nā wai hoʻoheheʻe: DOT 3, DOT 4, DOT 5, DOT 5.1.

1. Hiki i ka DOT 3 ke pale i nā mahana: 205 kekelē - no kahi wai "maloʻo" a me 140 kekelē - no kahi "ʻūlū". Hoʻohana ʻia kēia mau wai ma lalo o nā kūlana hana maʻamau i nā kaʻa me nā palaka pahu a i ʻole nā ​​disc.
2. Hoʻohana ʻia ʻo DOT 4 ma luna o nā kaʻa me nā paleki disc ma ke kaona kaiāulu (mode acceleration-deceleration). ʻO ke kiko paila ma aneʻi he 230 kekelē - no kahi wai "maloʻo" a me 155 kekelē - no kahi "ʻūlū". Kūleʻa kēia wai i nā kaʻa o kēia au.
3. Hoʻokumu ʻia ka DOT 5 me ka silicone a ʻaʻole kūlike ia me nā wai ʻē aʻe. ʻO ke kiko paila no kēlā wai e 260 a me 180 kekelē. ʻAʻole kūpale kēia wai i ka pena a ʻaʻohe omo i ka wai. Ma ke ʻano he kānāwai, ʻaʻole pili i nā kaʻa hana. Hoʻohana mau ʻia ia i nā kaʻa kūikawā e hana ana i nā mahana wela loa no ka ʻōnaehana braking.
4. Hoʻohana ʻia ʻo DOT 5.1 i nā kaʻa haʻuki a loaʻa kahi kiko e hoʻolapalapa ai e like me DOT 5.

ʻO ka viscosity kinematic o nā ʻano wai āpau ma kahi mahana o +100 kekelē ʻaʻole i ʻoi aku ma mua o 1,5 sq. mm / s., a ma -40 - ʻokoʻa ia. No ka ʻano mua, he 1500 mm kēia ^ 2 / s, no ka lua - no 1800 mm ^ 2 / s, no ka mea hope - 900 mm ^ 2 / s.

No nā mea maikaʻi a me nā maikaʻi ʻole o kēlā me kēia ʻano wai, hiki ke ʻike ʻia ka mea aʻe:

• ʻo ka papa haʻahaʻa, ʻo ka haʻahaʻa ke kumu kūʻai;
• ʻo ka haʻahaʻa o ka papa, ʻo ke kiʻekiʻe ʻo hygroscopicity;
• ka hopena ma nā ʻāpana kāpili: DOT 3 corrodes nā ʻāpana kāpili a me DOT 1 fluids i kūlike ʻole me lākou.

Ke koho ʻana i kahi wai wili, pono ka mea ʻona e hāhai i nā ʻōlelo a ka mea hana.

Nā hiʻohiʻona o ka hana a me ka hoʻololi ʻana i ka wai wili

Ehia mau manawa e pono ai e hoʻololi i ka wai wili? Hoʻonohonoho ʻia ke ola lawelawe o ka wai e ka automaker. Pono e loli ke kinowai wili i ka manawa. ʻAʻole ʻoe e kali a kokoke i kona ʻano kokoke i ka pilikia.

Hiki iā ʻoe ke ʻike ma ke ʻano i ke kūlana o kahi mea i kona ʻano. Pono ka wai wili e homogeneous, aniani moakaka a manuahi o ka sediment. Eia hou, i nā lawelawe kaʻa, loiloi ʻia ka wahi paila o kahi wai me nā hōʻailona kūikawā.

ʻO ka manawa i koi ʻia no ka nānā ʻana i ke ʻano o ka wai i hoʻokahi manawa i ka makahiki. Pono e hoʻololi i ka wai Polyglycolic i kēlā me kēia ʻelua a ʻekolu paha makahiki, a me ka wai silikone - i kēlā me kēia ʻumi a ʻumikūmālima mau makahiki. Hoʻokaʻawale ʻia ka hope e kona kūpaʻa a me ka hoʻohui kemika, kū ʻole i nā kumu kūwaho.

hopena

Kau ʻia nā koi kūikawā i ka maikaʻi a me ka hoʻohui ʻana o ka wai wili, ʻoiai ka hilinaʻi ka hana paʻa o ka ʻōnaehana paʻa. Akā ʻoi aku ka maikaʻi o ka wai hoʻoheheʻe kiʻekiʻe i ka manawa. No laila, pono e nānā a hoʻololi iā ia i ka manawa.
