Hiki ke hoʻopilikino ʻia nā bolts hexagon hot dip galvanized
Hōʻike huahana
>>>
Nui nā inoa like ʻole no ka bolt hexagonal o waho, no ka laʻana, hiki ke kapa ʻia ʻo ia ka bolt hexagonal o waho, no ka laʻana, hiki ke kapa ʻia ʻo waho hexagonal bolt. Hiki ke kapa ʻia he bolt hexagonal waho. ʻO kēia ka manaʻo like. He ʻokoʻa wale nō ka hana pilikino. Ma hope o ka mālama ʻana i ka wela galvanizing surface, loaʻa ka hopena anti-corrosion.
1. Ua māhele ʻia nā kī maʻamau i a, b a me c. ʻO nā mea mua ʻelua he mau bolts i hoʻomaʻemaʻe ʻia, ʻaʻole i hoʻohana ʻia. ʻO ka ʻōlelo maʻamau, pili nā bolts maʻamau i nā bolts maʻamau Class C.
2. Hoʻohana mau ʻia nā bolts maʻamau o ka papa C i kekahi mau hoʻopili manawaleʻa a me nā pilina e pono ai e wehe. ʻO nā bolts maʻamau i hoʻohana mau ʻia i nā hale kūkulu hale ʻo M16, M20 a me M24. Hiki ke loaʻa i kekahi mau bolts crude i ka ʻoihana mechanical nā anawaena nui a me nā kumu kūikawā.

3. ʻOkoʻa ka mea o ka bolt ikaika kiʻekiʻe me ka bolt maʻamau. Hoʻohana mau ʻia nā bolts ikaika kiʻekiʻe no nā pilina paʻa. ʻO ka mea maʻamau ka M16~M30.
Hoʻohana ʻia ka pā kau like no ka pilina ma waena o ka pā hoʻokahi a me ka pā hoʻokahi, a ma waena o ka pā hoʻokahi a me ka pā pālua. Hiki ke hoʻololi wale i ka lōʻihi o ka hui, akā ʻaʻole ke kuhikuhi pili. Hana ʻia ka pā kau like me ka pā kila ma ke kaʻina ʻana a me ke ʻoki ʻana. ʻO ka papa hana o waho hexagon bolt he ʻelua mau helu, e hōʻike ana i ka waiwai o ka ikaika tensile nominal a me ka ratio ikaika o ka mea bolt.
No ka laʻana, ʻo nā bolts me ka pae hana 4.6 mean:
a. Mea Bolt: hiki i ka ikaika tensile nominal i 400MPa;
b. ʻO ka lākiō hua o ka mea bolt he 0.6;
c. ʻO ka ikaika hāʻawi inoa o nā mea bolt a hiki i ka 400 × 0.6 = 240mpa papa.
Hiki i nā bolts ikaika kiʻekiʻe me ka helu hana o 10.9 ke hoʻokō i nā koi ma hope o ka mālama ʻana i ka wela:
a. ʻO ka mea Bolt, ka ikaika tensile nominal a hiki i 1000MPa;
b. ʻO ka ikaika hāʻawi inoa o nā mea bolt a hiki i ka 1000 × 0.9 = 900MPa papa.
