Ka lā pau o ka wai kaʻa

Nā kumu o ka emi ʻana o ka maikaʻi

ʻO ka hui ʻana o ka wai hoʻoheheʻe he polyglycols, boric acid esters, a ʻo Dot 5 nā poly-organosiloxanes (silicones). Me ka ʻokoʻa o ka mea hope, ʻo nā mea āpau i luna he hygroscopic. Ma muli o ka hana, hoʻopili ka mea i ka wai mai ka lewa. Ma hope iho, ua wela ka ʻōnaehana hydraulic, wela ka wai ma nā pā hydraulic i ka mahana evaporation a hana i kahi laka mahu. Lilo ka hele wāwae wāwae i ka laina ʻole a hoʻemi ʻia ka maikaʻi o ka brake. I ka hiki ʻana i ka 3,5% o ka wai ma ka leo, ua manaʻo ʻia ʻo TF he kahiko, a ma ka 5% a ʻoi aku paha, ʻaʻole kūpono ia no ka hoʻohana.

ʻO nā ʻano ʻenehana o ka wai e pili ana i ka mahana ambient. ʻOi aku ka wela o ka wā, ʻoi aku ka kiʻekiʻe o ka haʻahaʻa, a e nalowale koke ka TJ i kāna hana.

I ka manawa hea e pani ai?

Hōʻike ka mea hana i ka lā o ka hana ʻana, ke ola a me ka hana ʻana ma ka ipu. Hoʻopili pololei ka hui kemika i ka lōʻihi o ka noi. No ka laʻana, ʻo Dot 4 ka mea, me ka glycols, esters o ka boric acid, ka mea e hoʻopaʻa ai i nā molekule wai i loko o nā hydroxo complexes a hoʻonui i ke ola lawelawe a hiki i 24 mau mahina. ʻO kahi lubricant Dot 5 like, ma muli o ke kumu silicone hydrophobic, he hygroscopic iki a hiki ke mālama ʻia a hiki i 12-14 mau makahiki. ʻO ka Dot 5.1 e pili ana i nā ʻano hygroscopic, no laila ua hoʻokomo ʻia nā mea hoʻohui hoʻopaʻa wai kūikawā i loko, e hoʻonui ai i ke ola o ka papa i 2-3 mau makahiki. ʻO ka wai hygroscopic nui loa ʻo Dot 3 me ke ola lawelawe o 10-12 mau mahina.

ʻO ka awelika o ka mālama ʻana i ka wai kaʻa he 24 mahina. No laila, pono e hoʻololi i ka hōʻailona mua o ka emi ʻana o ka pono o ka ʻōnaehana brake a i ʻole ma hope o kēlā me kēia 60 tausani mau kilomita.

Pehea e nānā ai i ke kūlana?

Hiki ke hoʻoholo i ka maikaʻi o ka lubrication hydraulic me ka hoʻohana ʻana i kahi mea hōʻike kūikawā. ʻO ka hāmeʻa he māka lawe lima me kahi hōʻailona koʻikoʻi. Hoʻohaʻahaʻa ʻia ka mea hōʻike i loko o ka pahu me kahi poʻo hōʻike, a hōʻike ʻia ka hopena ma ke ʻano o kahi hōʻailona LED e hōʻike ana i ka ʻike wai. No ka mālama ʻana i ke kaʻina hana wela o ka TJ (150-180 °C), ʻaʻole pono ka nui o ka wai ma mua o 3,5% o ka nui o ka nui.

Pehea ka lōʻihi o ka hoʻopaʻa ʻana o ka wai i loko o ka pūʻolo?

I loko o kahi pahu pani, ʻaʻole pili ka mea me ka ea a mālama i kāna mau ʻenehana. Eia nō naʻe, i ka wā lōʻihi, hoʻohaʻahaʻa maoli kekahi mau pūhui. ʻO ka hopena: hoʻololi ka helu hoʻolapalapa a me ka viscosity o ka huahana. Wahi a nā kūlana honua, ʻo ka mālama ola o nā wai kūikawā i loko o ka ʻeke i wehe ʻole ʻia, me nā wai hoʻomaha, ua kaupalena ʻia i 24-30 mau mahina.

Nā ʻōlelo paipai no ka hoʻohana ʻana a me ka mālama ʻana

Nā ʻōlelo aʻoaʻo maʻalahi e hoʻolōʻihi i ke ola o TJ:

• E mālama i nā mea i loko o kahi pahu paʻa paʻa.
• ʻAʻole pono ka haʻahaʻa o ka ea i loko o ka lumi ma mua o 75%.
• E pani paʻa i ka poʻi pahu pahu a mālama i ka maʻemaʻe o nā puka komo ea.
• E hoʻololi i ka wai i kēlā me kēia 60000 km.
• E nānā i ka paʻa o nā awāwa o ka ʻōnaehana brake.

I kēia manawa ua ʻike ʻoe i ka lōʻihi o ka mālama ʻia ʻana o ka wai brake a me nā mea e pili ana i kona maikaʻi.

ʻO nā mea a pau e pili ana i nā wai kaʻa
