Momwe mungasungire zida za bawuti zamphamvu kwambiri?

Maboti amphamvu kwambiri monga 12.9 bawuti, 10.9 bawuti, 8.8 mabawuti

1 Zofunikira zaukadaulo zamkulu mphamvu mabawuti kalasi

1) Maboti amphamvu kwambiri ayenera kukwaniritsa izi:

Zizindikiro zaukadaulo za ma bolts amphamvu kwambiri ziyenera kukwaniritsa zofunikira zaASTM A325 chitsulo bawuti zomangamangakalasi ndi mitundu, ASTM F436 zolimba zochapira zitsulo, ndi ASTM A563 mtedza.

2) Kuwonjezera pa kukwaniritsa miyezo ya ASTM A325 ndi ASTM A307, geometry ya bolt iyeneranso kukwaniritsa zofunikira za B18.2.1 mu ANSI. Kuphatikiza pa kukwaniritsa miyezo ya ASTMA 563, mtedza uyeneranso kukwaniritsa zofunikira za ANSI B18.2.2.

3) Otsatsa amatsimikizira ma bolts amphamvu kwambiri, mtedza, ma washer ndi magawo ena amisonkhano yomangirira kuti awonetsetse kuti ma bolts omwe amagwiritsidwa ntchito ndi odziwika ndikukwaniritsa zofunikira za ASTM. Maboti amphamvu kwambiri amasonkhanitsidwa ndi wopanga m'magulu Kuti apereke, wopangayo ayenera kupereka chiphaso cha chitsimikiziro chamankhwala pagulu lililonse.

4) Woperekayo ayenera kupereka mtedza wothira mafuta omwe ayesedwa ndi ma bolts amphamvu kwambiri omwe amaperekedwa.

2. mabawuti amphamvu kwambiri pamapangidwe achitsuloKusungirako mabawuti

1) Maboti amphamvu kwambiriziyenera kukhala zosagwirizana ndi mvula, zotetezedwa ndi chinyezi, ndi zotsekedwa panthawi yoyendetsa ndi kusungirako, ndipo ziyenera kuikidwa ndi kutsitsa mopepuka kuti ziteteze kuwonongeka kwa ulusi.

2) Pambuyo pa ma bolts amphamvu kwambiri kulowa pamalopo, ayenera kuyang'aniridwa molingana ndi malamulo. Pokhapokha pambuyo poyang'anira nditha kuyika muzowerengera ndikugwiritsa ntchito kupanga.

3) Gulu lililonse lamabawuti amphamvu kwambiriayenera kukhala ndi satifiketi ya fakitale. Mabawuti asanasungidwe, gulu lililonse la ma bolt liyenera kuyesedwa ndikuwunikiridwa. Pamene mabawuti amphamvu kwambiri asungidwa, wopanga, kuchuluka, mtundu, mtundu, mawonekedwe, ndi zina zotero ziyenera kufufuzidwa, ndipo nambala ya batch ndi mafotokozedwe (zolembedwa (kutalika ndi m'mimba mwake) zimasungidwa m'magulu athunthu, ndipo zimatetezedwa ku. Chinyezi ndi fumbi panthawi yosungiramo pofuna kupewa dzimbiri ndi kusintha kwa malo, kusungirako kotseguka ndikoletsedwa.

4) Maboti amphamvu kwambiri ayenera kusungidwa m'magulu molingana ndi nambala ya batch ndi mafotokozedwe omwe akuwonetsedwa pabokosi lonyamula. Ayenera kusungidwa m'chipinda chapamwamba m'nyumba ndipo asamasungidwe zosanjikiza zisanu. Osatsegula bokosilo momwe mukufunira panthawi yosungirako kuti muteteze dzimbiri ndi kuipitsidwa.

5) Pamalo oyikapo, ma bolts ayenera kuikidwa mu chidebe chosindikizidwa kuti asatengeke ndi fumbi ndi chinyezi. Maboti okhala ndi dzimbiri ndi fumbi lambiri sagwiritsidwa ntchito pomanga pokhapokha atavomerezedwa molingana ndi ASTM F1852.
