Nānā maʻiʻo o nā mea hoʻopaʻa

ʻO nā mea hoʻopaʻa, ʻike ʻia hoʻi ʻo nā ʻāpana maʻamau i ka mākeke, he huaʻōlelo maʻamau no ke ʻano o nā ʻāpana mechanical i hoʻohana ʻia no ka hoʻopili paʻa ʻana i ʻelua mau ʻāpana (a i ʻole nā ​​ʻāpana) i kahi holoʻokoʻa. Ua kapa ʻia lākou he "mika ʻoihana" a loaʻa nā noi ākea ma nā kula e like me nā mīkini, nā mea hana, nā kaʻa, nā moku, nā alahao, nā alahaka, nā hale, nā hale, nā mea hana, nā mea hana, nā mea hana, a me nā lako.

ʻO nā mea nānā i ka hana o nā mea hoʻopaʻa: ka nui, ka haku mele, ka hoʻāʻo ʻole luku ʻole, nā waiwai mechanical e pili ana i ka coefficient pili bolt o ka torsion, ka hoʻopaʻa ʻana i ka ikaika axial, tensile (ikaika hua, ikaika tensile), paʻakikī, a me nā waiwai mechanical e hoʻāʻo ana i nā mea hoʻopili kila.

Nā māka hana obolts no ke kila kilahui pū ʻia ʻo 4.6, 4.8, 6.8, 8.8,10.9, 12.9, etc. Kākoʻo ʻia nā bolts o ka papa 8.8 a i luna e ka hao hao haʻahaʻa haʻahaʻa a i ʻole ke kila kalapona waena a me ka wela wela, i kapa ʻia maʻamau.bolts ikaika kiʻekiʻe, a ua kapa mau ia ke koena he mau bolts ma'amau

Nānā maʻiʻo o nā mea hoʻopaʻa

1. Nā hiʻohiʻona hiʻohiʻona: ke anawaena hele / ʻaʻole hele, ka ʻili o ka ʻili, nā ʻano like ʻole e like me ke anawaena nui, ke anawaena pitch, ke anawaena liʻiliʻi, ke kihi profile, ka pitch, etc.

2. Mechanical hana ho'āʻo: tensile ho'āʻo, hoʻopaʻa ho'āʻo, paakiki ho'āʻo, re tempering ho'āʻo, hopena ho'āʻo, wedge haawe hoao, shear ho'āʻo, luhi ho'āʻo, laka hana, torque coefficient, tightening axial ikaika, friction coefficient, anti slip coefficient, screwability test, gasket elasticity, toughness test, hydrogen emm.

3. Ka hoʻopili ʻana i ka haku mele: hoʻopaʻa hoʻopaʻa ʻana i ka haku mele ʻana, ka mea hoʻopaʻa metala mea ʻike papa, etc.

4. Ke kālailai metallographic: microstructure, hohonu o ka decarburization papa, hohonu o ka carburization papa, palaoa nui helu, inclusion maʻiʻo, macrostructure, etc.

5. Ka nānā 'ana i ka hāʻule ʻana: ka nānā ʻana i ka māwae, ka nānā ʻana i ka haʻihaʻi, ka nānā ʻana i ka haʻihaʻi, etc.

6. ʻO ka hoʻāʻo kūʻē ʻana i ka corrosion: ka hoʻāʻo ʻana i ka paʻakai paʻakai kūʻokoʻa (NSS), ka hoʻāʻo ʻana i ka acetate spray (AASS), ke keleawe accelerated acetate spray test (CASS)
