Ma ka'ōnaehana brake pneuamtic brake,ʻo ia ka ea i hanaʻia e hana i ka hana hana hana e mālama ai i kahi hoʻoikaika hana paʻa e hoʻomaʻemaʻe i ka hana maʻamau o ka'ōnaehana maʻamau. Ua hoʻolālāʻia nā meaʻelua o ka molena molele a me ka haunaele o ka ea a me ka hau no keʻano o ka'ōnaehana ma kahi o ka'ōnaehana maʻamau (maʻamau ma 8 ~ 10bar).
Ma ka'ōnaehana kaʻa kaʻa,ʻo ka ea wela o ka ea e like me ka waihoʻoluʻu wai, inā e hoʻokaʻawaleʻia i nā meaʻala
Hoʻohanaʻia ka mīkini mīkini pahu kaʻa e wehe i ka wai, ua hāʻule nā aila a me nā mea'ē aʻe i ka lewaʻoi aku, ma mua o ka hāleʻa hāwanui. A hoʻohanaʻia no ka hōʻoluʻoluʻana i ka wai lāʻau, e hoʻololi ana i ka wai maʻemaʻe no ka makani maʻemaʻe.
ʻO ka mīkini mīkini kaʻa kaʻa kaʻa he mea hoʻohana houʻia me kahi mea e noho ai ka molecular e like me kona desiccant. ʻO Jz-404b Molecular Sieve kahi huahana Desiccant synthetic i ka hopena adsoppled me ka hopena adsopption ikaika ma luna o nā molekula wai. ʻO kāna māhele nui heʻano micropoous o keʻanoʻo Alkili Metal all alumini silitate me nā lole likeʻole a me nā lua a me nā lua. ʻO nā molekele wai a iʻole nā molena'ē aʻe e hoʻolahaʻia i kaʻaoʻao o loko o loko o ka lua, me ka hana o ka nohoʻana i nā molekula. ʻO ka Molecular Sieve he nui ka nui o ka nui o ka rula nui a paʻa mau i nā molela wai i nā mollecules maikaʻi ma nā kiʻekiʻe o 230 ℃.
E noho mālie ka nohoʻana o ka pūnaehana ma ke'ōnaehana a pili i ka hopena hua, a hiki iā ia ke kumu i ka hanaʻole o ka'ōnaehana braking. No laila, pono e ukuʻia ka nānāʻana i ka wai pinepine o ka wai i ka'ōnaehana a me ka hoʻololi maʻamau o ka molena mole.
