ʻO ka wai kaʻa "Neva". Hoʻomaopopo i nā ʻāpana
He aha ke kala ʻo Neva brake fluid?
ʻO nā hōʻailona organoleptic e hoʻoholo ana i ke kūpono o nā wai hoʻoheheʻe no ka hoʻohana ʻana:
- chromaticity;
- ʻaʻohe sediment mechanical;
- kaawale ʻole i ka wā mālama lōʻihi.
I ka manawa like, ʻaʻole o ke ʻano koʻikoʻi ka helu kala, akā e hōʻike wale ana i ka hoʻohui ʻana o nā mea hoʻohui i hoʻokomo ʻia i loko o ka wai kaʻa i mea e hoʻomaikaʻi ai i kāna mau lubricating a me ka hoʻoluʻu ʻana, hiki i ka oxidation a me ka paʻa o ka helu acid. No laila, pono e kūʻai ʻia ʻo Neva i loko o ka pahu aniani e kū ana i nā koi o GOST 1510-76, ʻoiai inā pili kēia i ke kumukūʻai o ka huahana.
E like me ka kikoʻī TU 6-09-550-73, ʻo Neva brake fluid (a me kona hoʻololi ʻana ʻo Neva-M) pono e loaʻa i kahi kala melemele waiwai me ka hiki ke opalescence liʻiliʻi (hoʻonui i ka hoʻopuʻi kukui i nā mahana e kokoke ana i ka koʻikoʻi). He ʻeleʻele iki ke kala o ka wai i hoʻohana mua ʻia.
Hoʻopili ʻia kēlā me kēia ʻokoʻa i ke kala me ka piʻi ʻana o nā mānoanoa a me nā mea hoʻohui anti-corrosion i nā mea nui - ethyl carbitol a me boric acid esters. ʻAʻole ʻōlelo ʻia ʻo "Neva" o kahi kala ʻē aʻe no ka hoʻohana ʻana i nā haʻahaʻa haʻahaʻa haʻahaʻa, no ka mea, ʻo ka piʻi ʻana o ka viscosity e alakaʻi i ka piʻi nui o ka ikaika o ke kaomi ʻana i ka pedal brake, a no nā kaʻa i lako ʻia me ABS, hiki iā ia ke hana i ka hemahema o kēia ʻōnaehana. .
Nāʻano
Ua hoʻomohala ʻia ʻo Neva universal brake fluid i ka manawa hoʻokahi no ka hoʻohana ʻana i nā kaʻa kaʻa kaʻa kūloko e like me Moskvich a me Zhiguli, a no laila ua paʻa piha me nā wai kaʻa e like me Tom a me Rosa. ʻO kāna mau waiwai kino a me ka mechanical penei:
- Ka wela o ka hoʻohana pono - ± 500H.
- Ka helu paila mua - 1950H.
- Kinematic viscosity, cSt, ma nā mahana a hiki i 500C - ʻaʻole ʻoi aku ma mua o 6,2.
- Kinematic viscosity, cSt, ma nā mahana a hiki i -400C - ʻaʻole ʻoi aku ma mua o 1430.
- ʻAʻole hiki ke hana corrosive i nā metala ʻē aʻe.
- ʻO ka mahana ma ka hoʻomaka o ka mānoanoa -500H.
- Hoʻololi ka wela ma hope o ka mālama ʻana i ka wā lōʻihi - ±30H.
- Kiko uila - 940H.
- ʻO ka pehu volumetric o nā ʻāpana lāʻau i nā mahana a hiki i 1200C, ʻaʻole ʻoi aku ma mua o 3%.
Hiki ke ho'opō'ino li'ili'i inā pili kēia wai ka'a me nā'āpana alumini no ka manawa lō'ihi.
Nā hana hoʻolālā
No ka papa DOT-3 ʻo Neva a me Neva M nā wai kaʻa. Wahi a ka pae honua, ʻo ka hoʻokaʻawale ʻana o nā mahana i ʻae ʻia no ka wai "maloʻo" a me ka "mā" o kēia papa he 205, kēlā me kēia.0C a me 1400H. Eia kekahi, me ka mālama ʻole ʻia, ʻae ʻia ka lawe ʻana o ka wai makahiki a hiki i ka 2 pakeneka o kona nui. No laila, ʻoi aku ka nui o ka wai i ka ʻino i loko o ka ʻōnaehana kaʻa kaʻa, hiki ke alakaʻi i nā pilikia e like me ka pale ʻana i ka uahi a i ʻole ka holo wāwae.
Hiki ke hoʻololi ʻia nā wai kaʻa DOT-3 a me DOT-4 no ka mea he kumu maʻamau ko lākou. Pono e hoʻomaopopoʻia he nui o nā mea hana o Neva a me kāna mau analogues (ʻo ia hoʻi, Neva-super, i hanaʻia e Shaumyan Plant OJSC, St. Petersburg) e haʻi aku i ka hoʻohanaʻana i ka polyalkylethylene glycol ma keʻano he mea nui o ka haku mele. Eia naʻe, kokoke nā waiwai kemika o ka ethyl carbitol a me ka polyalkylethylene glycol, a no laila ʻaʻohe kumu e pale ai i ka hui ʻana iā Neva mai nā mea hana like ʻole.
ʻO kahi hiʻohiʻona koʻikoʻi o ka wai hoʻoheheʻe ʻo Neva kona ʻona, pono e noʻonoʻo ʻia i ka wā e nānā ai i nā lula palekana i ka wā e hoʻohana ai.
ʻO ke kumukūʻai o ka wai hoʻoheheʻe "Neva" a me kāna mau analogues e hilinaʻi ʻia i kāna ʻeke:
- I loko o nā pahu o 455 ml - mai 75 ... 90 rubles.
- I loko o nā pahu o 910 ml - mai 160 ... 200 rubles.
