ʻO nā bolts Hub he mau pahu ikaika kiʻekiʻe e hoʻohui i nā kaʻa i nā huila. ʻO ka wahi hoʻohui ʻo ia ka ʻāpana hub e lawe ana i ka huila! ʻO ka maʻamau, hoʻohana ʻia ka papa 10.9 no nā kaʻa liʻiliʻi, hoʻohana ʻia ka papa 12.9 no nā kaʻa nui! ʻO ke ʻano o ka hub bolt ma ke ʻano he faila kī knurled a me kahi faila kaula! A he poʻo pāpale! ʻO ka hapa nui o nā wili huila poʻo T-like ma luna o ka 8.8 papa, e lawe ana i ka pilina torsion nui ma waena o ka huila kaʻa a me ke axle! ʻO ka hapa nui o nā pōkā huila poʻo ʻelua ma luna o ka papa 4.8, ʻoi aku ka maʻalahi o ka hoʻopili ʻana ma waena o ka pūpū huila waho a me ka huila.

E pale maikaʻi i nā U-bolts mai ka ʻōpala
ʻO ka ʻenehana uhi ma ka ʻili o nā mea hoʻopaʻa e like me nā U-bolts maʻamau maʻamau galvanized, hiki ke alakaʻi i nā hōʻailona o ka ʻōpala ma hope o ka hoʻohana ʻia ʻana ma mua o 1 makahiki. I ka wā e hoʻopili ʻia ai, ʻaʻole ia e hoʻopili wale i ka helehelena a me ke ʻano, akā pili pū kekahi i kāna hana i ka hopena nui i ka hoʻohana ʻana i nā mea hana, no laila i kā mākou hoʻohana ʻana, pono mākou e hoʻolohe i nā kūlana kumu e pale ai i ka pala.
ʻO ka mua, e maloʻo ka ʻili o ka U-bolt i hiki iā mākou ke pale i ka nui o ia mea.
1. ʻO ka hoʻopili ʻana i ka lepo a i ʻole nā mea metala ʻē aʻe, i loko o ka ea haʻahaʻa, ka wai condensed i hoʻopili ʻia a me nā wili kila kila, e hoʻopili i nā mea ʻelua i loko o kahi micro-battery, e hoʻoulu ai i nā hopena electrochemical behavioral, a ua maʻalahi ka pōʻino o ke kiʻi pale. kapa ʻia ʻo electrochemical Analyze corrosion..
2. ʻO ke kila kila U-bolt e pili ana i ka ʻili o ka wai kūlohelohe, me ka ʻole o ka wai a me ka oxygen e hana ai i kahi waikawa organik, ʻo ka waikawa organik kahi corrosion lōʻihi ma ka ʻili o ka mea metala.
3. ʻO ka hoʻopili ʻia ʻana o nā mea kila kila U-bolts, alkali a me ka paʻakai paʻakai ke kumu o ka corrosion kūloko o nā haumāna.
4. I kekahi ea haumia (e like me ka nui o nā sulfides like ʻole, carbon oxides, nitrogen oxides i koʻu ʻāina), ka wai i hoʻoheheʻe ʻole ʻia ke kumu wai o ka sulfuric acid, nitric acid, a me ka acetic acid, e kumu i nā haumāna. i ka hoʻoheheʻe ʻana i ke kino.
