Ka hōʻailona ʻana i nā mea holoi paʻa

“Pono e kaha ʻia nā mea holoi palahalaha?” "ʻAʻole?"

“Pono lākou?”……

I kēia lā ke kūkākūkā nei mākou i kēia pilikia me ʻoe, e manaʻo paha ka nui o ka poʻe o ka ʻoihana“ʻO Xiaowan ah, he ʻano hana ʻole ʻoe ……”.

E like me kā mākou e ʻike ai, ʻo nā mea holoi paʻa e like me ka pilina paʻa o kahi kūpono koʻikoʻi, ka mea nui i ka hoʻonui ʻana i ka wahi hoʻopili, e hoʻopuehu i ka hana o ke kaomi pili. ʻO ka hapa nui o nā mea holoi pālahalaha i hoʻohana ʻia i ka hui ʻoihana ʻaʻole i hōʻailona ʻia e like me ke kiʻi ma lalo nei.

No laila he aha nā hihia kahi e hōʻailona ʻia ai nā mea holoi pālahalaha?

(1) Mea kanu hana e pale i ka hui ʻana i nā mea

ʻO nā mea holoi paʻa no ke kaʻina hana o ka hoʻoheheʻe ʻia ʻana o ka ʻili ʻili, ka mea kanu i loko o ka papa holoi holoi paʻa e hōʻailona ʻia i mea e pale aku ai i ka hana ʻana o nā kikoʻī like ʻole o nā mea like ʻole nā ​​mea holoi holoi, i ka hana a i ʻole ka transit kaʻina o ka huikau waiwai a me ke ʻano o ke kaʻina hana. No ka laʻana, ka“304”i ke kiʻi aʻe, ʻo ia hoʻi, ma ka ʻaoʻao o ka mea holoi pālahalaha he mea A2. Inā hana ka mea hana i kahi mea holoi palahalaha o ka kikoʻī like ma 316 mea i ka manawa like, a laila hiki ke kaha ʻia ka mea holoi me ka“316”or “A4”.

ʻO kēia hōʻailona o ka ʻike waiwai he mea maʻamau i nā mea hoʻomaʻemaʻe kila kila, ʻo ke kumu ma hope o ka hana ʻana o nā huahana stainless steel e hana wale ʻia ma hope o ka hoʻomaʻemaʻe a me ka passivation, mai ke ʻano o ke keʻokeʻo keʻokeʻo, ʻaʻole hiki ke hoʻokaʻawale intuitively i kāna mea.

ʻIke ʻia ka mea ma ka ʻili o nā mea hoʻomaʻemaʻe kila kila hiki ke pale maikaʻi i ka hana ʻana a i ʻole ka hui ʻana o nā mea i hui ʻia.

(2) nā hoʻolako maʻamau

Hōʻike kekahi mau huahana huahana i nā koi o nā mea holoi pālahalaha i kaha ʻia, no ka laʻana, ka maʻamau“EN”, “EN”, “EN”, “EN”, “EN”a“EN”.

Eia kekahi laʻana, ka maʻamau“EN 14399-5 (GB / T 32076.5) i hoʻouka mua ʻia i nā hui hoʻohui i hoʻopaʻa ʻia me ka ikaika kiʻekiʻe.”i loko o nā mea holoi holoi paʻa i hoʻopaʻa ʻia a hoʻoluhi ʻia, pono e hōʻailona ʻia me kahi concave, e like me ka mea i hōʻike ʻia ma lalo nei.

Eia kekahi laʻana, ka maʻamau“ʻO ASTM F436 nā mea holoi kila paʻakikī”e hōʻailona ʻia nā mea holoi paʻa e pili ana i kēia maʻamau me ka“F436”hōʻailona, ​​e like me ka mea i hōʻike ʻia ma lalo nei:

Hiki ke ho'okumu 'ia nā mea holoi lole pa'a i kaha 'ole 'ia me ka ma'amau?

Ke nānā nei i nā kūlana huahana o kēia manawa, ʻaʻole i wehewehe maopopo ʻia nā maʻamau no nā mea holoi pālahalaha inā e pāʻani i ka māka.

ʻO ISO 898-3: 2018 (nā waiwai mīkini o nā mea paʻa - nā mea holoi paʻa) ʻO ka maʻamau ka hoʻokō ʻana i nā koi hana no ke kila kalapona, nā mea hao hao hao ʻia i ka 2018, nona ka mokuna 9.2 no ka hoʻomaʻamaʻa ʻana i nā mea hoʻomaʻamaʻa paʻa.

ʻO ka mākaʻikaʻi ʻana o ka washer flat ma ka manaʻo o ka mea hana a i ʻole ma ka ʻaelike ma waena o ka lako a me ke koi.

ʻAʻole e kaha ʻia nā mea holoi paʻa me nā leka hoʻokiʻekiʻe. ʻAʻole ʻōlelo ʻia ka māka concave no ka mea hiki iā ia ke hoʻololi i ka pilina o ka hui torque-clamping o ka hui bolt-nut a i ʻole e hana i nā koʻikoʻi koʻikoʻi e hiki ai ke pohā o ka mea holoi.

Hōʻike nā ʻōlelo ʻelua ma luna nei ʻaʻole koi ʻia ka mākaʻikaʻi ʻana i nā mea holoi pālahalaha, a na ka mea hoʻolako e hoʻoholo a kūkākūkā paha inā makemake ʻia ka māka ma mua o ke kauoha ʻana. ʻAʻole ʻōlelo ʻia e hōʻailona i ka ʻili o nā mea holoi pālahalaha me nā huaʻōlelo i hoʻopaʻa ʻia a concave paha.

Austenitic stainless steel flat washer surface concave marking will change the bolt – nut connecting vice torque – clamping force relationship is to be proved, it is certain that, ma muli o ka haʻahaʻa o ka austenitic stainless steel, concave marking ʻaʻole ia e alakaʻi i ke koʻikoʻi koʻikoʻi i ka washer, ʻaʻole ia e hoʻomaka i ka haki ʻana o ka mea holoi.
