ʻO nā Bolts i uhi ʻia ʻo Dacromet a me nā Nati 

Hōʻike kēia ʻatikala i nā ʻohana paʻa e pili ana, nā ʻano hana ʻino e hoʻouka ai i nā hui wili, no ke aha e hoʻopili ai ʻo Dacromet i nā bolts a me nā nati like, a pehea e wehewehe ai a hoʻohui i kahi pūʻulu bolt-nut-washer.

2. Pehea e hoʻouka ai ʻo Corrosion i kahi hui wili

ʻO nā milo ka geometry hikiʻole i ka corrosion-vulnerable ma kēlā me kēia hui paʻa.

1.Crevice corrosion- ʻo ka ʻokoʻa liʻiliʻi ma waena o ka ʻaoʻao o ke kaula bolt a me ka ʻaoʻao nat thread e hoʻopaʻa i ka makū a me ka electrolyte, e hana ana i kahi puʻupuʻu pōloli oxygen kahi e hana ai nā wahi anodic a lua ana hoʻomaka;

2.Galvanic corrosion- nā ʻāpana ʻokoʻa a i ʻole nā metala (kahi pahu Dacromet me kahi nati i hoʻopaʻa ʻia i ka electro-plated, kahi pahu kuhili i loko o ka nut galvanized) e hoʻokau i ka ʻino o ka mea ʻoi aku ka hanohano;

3.Coating pōʻino ma ka hui- ʻāwīwī ʻia nā kaula i ka wā e paʻa ai; ʻoki maʻalahi i ka electroplate lahilahi a me nā pena organik, e hōʻike ana i ke kila kila i loko o nā aʻa o ke kaula;

4. Koʻikoʻi koʻikoʻi- ʻo ke kaula haʻahaʻa mua e lawe i ka hapa like ʻole o ka preload, no laila lilo koke nā lua ʻino ma laila i mau māwae luhi;

5. Fretting ma lalo o ka haʻalulu- ʻO ka micro-movement ma waena o ke alo o ke alo e hoʻopau i ke kiʻiʻoniʻoni, e kono ana i ka ʻele keʻokeʻo a laila ʻulaʻula.

I ka wā e ulu ai nā hua ʻōpala i loko o nā kaula, hopu ka nut, ʻoi aku ka nui o ka torque disassembly ma mua o ka torque hoʻonohonoho ʻana, a ʻoki pinepine ʻia ka pahu a i ʻole ka stud - ʻo ka "hua hau" maʻamau i ka mālama ʻana.

3. Paʻa ʻino o ka Set i hoʻohālikelike ʻia

Papa 1. Hoʻohālikelike ʻia nā ʻōnaehana uhi no nā hui bolt-nut (nā waiwai ʻoihana maʻamau).

No ka mea ua hoʻohana ʻia ka uhi ʻana i nā ʻāpana i hoʻopau ʻia, mālama ʻia i ka wela a hoʻōla ʻia ma lalo o ka mahana wela, mālama nā bolts a me nā nuts i kā lākou mau waiwai mechanical piha - ka ikaika tensile, ka ukana a me ka paʻakikī no ISO 898-1 / ISO 898-2 - ʻaʻole i loli.

4. ʻO nā hana maikaʻi loa o ka Hui

1.Never hoʻohui i nā ʻōnaehana uhi- e hoʻohui i nā bolts Dacromet me nā nati Dacromet a me nā mea holoi; hoʻokuʻu ʻia kahi hui hui ʻia i ka ʻino galvanic o ka ʻāpana nāwaliwali (maʻa mau i ka zinc-plated);

2. E mahalo i ka papa ʻaina- ʻO nā hui Dacromet lubricated he haʻahaʻa haʻahaʻa, ʻoi aku ka paʻa paʻa ma mua o ke kila kila; ʻo ka hoʻohana hou ʻana i nā waiwai torque kahiko e ʻoi aku ka paʻa a hiki ke wehe i nā kaula nut;

3. Mai lubricate hou- ua hoʻonohonoho mua ka ʻaʻahu i hoʻohui ʻia i ke koena friction; ʻO ka aila hou ma luna o nā milo e hoʻololi K unpredictably;

4. E noʻonoʻo i ke kauoha jam-nut- ke hoʻopaʻa ʻia ka nati lahilahi a me ka nati piha (ka hoʻonohonoho paʻa maʻamau), e hoʻopaʻa i ka nati piha i ka nati lahilahi;

5. E kiaʻi no ka ʻāʻīma luna o nā hui kuhiliʻole - ʻo Dacromet's lubricant topcoat e hōʻemi ana hoʻi i ka maʻi ʻeha ma nā studs stainless;

6.E hōʻoia i ka ʻatikala mua torque-tensionma kahi skid hoʻāʻo, me ka hoʻohana ʻana i ka hui ʻana o ka bolt-nut-washer maoli mai ka papa hana.

5. Ka hopena

ʻAʻole hoʻomaka ka pōʻino ma ka ʻāʻī o ka pahu - hoʻomaka ia ma nā kaula, ma ka ʻāʻī ma waena o ka pahu a me ka nati. No laila koi ʻia kahi hui paʻa a pūʻolo pale pale ʻino: Dacromet-coated bolts, nuts and washers in the same zinc-flake system, specifically together (ISO 10683 / ASTM F1136, flZn 8/10, ≥ 720 h NSS), i hui pu ia me ka torque pololei a me ka waiwai friction. ʻO ka hopena, ʻo ia ka pilina pili e kūʻē i ka ʻōpala keʻokeʻo, ka ʻulaʻula, ka lua, ka hoʻouka ʻana a me ka hopu ʻana - i nā makahiki o ka paʻakai paʻakai, ka wā a me ka haʻalulu.
