ʻO ka nānā ʻana o ke kaʻaU-boltspono e uhi i nā ana, nā waiwai waiwai, ka hana mechanical, a me nā mea ʻē aʻe. ʻO nā kūlana kiko'ī penei:
1. Nānā Pono Pono?
Nā mea ana: ʻO ka lōʻihi, ka laulā, ka mānoanoa, ka pololei o ke kaula, a me nā mea ʻē aʻe, me ka hoʻohana ʻana i nā calipers, micrometers, a i ʻole nā mea hana pono e hōʻoia i ka hoʻokō ʻana i nā koi hoʻolālā.
Nā Manaʻo Hoʻomanawanui: I ka nānā ʻana i ke kaula kūpono me nā ana go/no-go, pono e wili pono ka ana "go", aʻo ka ana "no-go" ʻaʻole pono ma mua o 2 huli.
2. Nānā maikaʻi o ka ʻili?
Nānā Kiʻi: Pono ka ʻili e maʻemaʻe, ʻaʻohe ʻōpala, nā māwae, nā ʻōpala, a i ʻole nā hemahema ʻē aʻe (nānā ʻia e ka nānā ʻike a i ʻole ka hoʻāʻo ʻana).
Ke nānā ʻana i ka uhi: Pono ke ʻano o ka uhi galvanized, me ka mānoanoa e hālāwai me nā kūlana (e laʻa, ka hoʻāʻo ʻana i ka paʻakai no ka hōʻoia kūʻē ʻana i ka corrosion).
3. Mea & Kemeka Hui
Hōʻoia Mea: Pono e hōʻoia ʻia ka hoʻopaʻa ʻana i ka hoʻokumu ʻana i nā mea hoʻohālikelike me ke kila kalapona (eg, Q235) a i ʻole ke kila kila (eg, 304).

4. Hoao Hana Mechanical?
Ka ikaika ʻo Tensile: Hōʻoia ʻia ma o ka hoʻāʻo ʻana, e hōʻoiaʻiʻo ana i nā haʻihaʻi i loko o ke kaula i hoʻopaʻa ʻia a i ʻole ka pae ʻole.
ʻO ka hoʻāʻo paʻakikī: Ana ʻia me ka hoʻohana ʻana i ka mea hōʻike paʻakikī e hōʻoia i ka hoʻokō ʻana i nā koi mālama wela.
Torque & Preload Testing: E hōʻoia i ka torque coefficient e hōʻoia i ka hoʻokomo pono.
5. Kaʻina Hana a me ka ʻike ʻino?
ʻO ke poʻo anu a me ka holo ʻana o ke kaula: E nānā i ka chamfering kūpono, nā ʻaoʻao ʻole burr, a ʻaʻohe hōʻailona o ka pōʻino.
Nānā Mākēneki Mākēneki (MPI): Hoʻohana ʻia no ka ʻike ʻana i nā māwae o loko, hoʻokomo ʻia, a i ʻole nā hemahema huna ʻē aʻe.
6. Nā kūlana a me ka hōʻoia?
Nā Kūlana Pono: E nānā iā QC/T 517-1999 (U-boltsno nā puna lau kaʻa) a i ʻole JB/ZQ 4321-97.
Packaging & Marking: Pono e hōʻike i nā kūlana aupuni; Pono nā poʻo bolt e pololei, a ʻo nā kaula e maʻemaʻe a ʻaʻohe mea haumia.
Nā memo hou aku:
No ka nānā ʻana i nā pūʻulu, koi ʻia nā hoʻokolohua hou e like me ke ola luhi a me ka naʻau o ka hydrogen embrittlement.
He 3-5 mau lā hana ka nānā ʻana, me nā hihia paʻakikī e hoʻonui ana i 7-10 lā.
No ka meaU-boltsnā nīnau, e ʻoluʻolu e kelepona mai iā mākou ma o nā kikoʻī ma lalo nei
