ʻO ka mea hana i nā mea paʻa (nā heleuma / bolts / screws ...) a me nā mea hoʻoponopono

Ke aʻo aku nei ka ʻenehana hoʻopaʻa FIXDEX iā ʻoe i ke ala nānā pono no ka hiki ke hoʻouka ʻia o nā heleuma wedge.

Nā hiʻohiʻona heleuma wedge:
ʻOi aku ka lōʻihi o ka heleuma o ka wedge a ʻoi aku ka maʻalahi o ka hoʻouka ʻana, a hoʻohana mau ʻia i nā hale hana kaumaha. No ka loaʻa ʻana o ka ikaika paʻa hilinaʻi a nui, pono ia e hōʻoia i ka hoʻonui piha ʻana o ke apo clamp i hoʻopaʻa ʻia ma ka pahu heleuma. Ke wili mau nei ka heleuma wedge a ʻaʻole e hāʻule ka pahu hoʻonui mai ka pou a wili paha i loko o ka lua. Hoʻāʻo ʻia nā koina tensile calibrated ma lalo o ke ʻano o ka ikaika sima o 260 ~ 300kgs / cm2, a ʻaʻole ʻoi aku ka nui o ka ukana palekana ma mua o 25% o ka waiwai calibrated.
Pono e hoʻokō pono ʻia nā ʻaoʻao a me ka spacing o ka heleuma wedge a me ka mānoanoa a me ka laulā o ka substrate e like me nā koi e hōʻoia i ka hiki ke hoʻokō pono o ka heleuma wedge. A i ʻole, hiki i nā mea kūkulu hale ke haki a haki paha.
Pono e ʻoi aku ka hohonu o ka wili ʻana o ka heleuma wedge Through bolt ma mua o ka hohonu o ka hoʻonui ʻana i ka hope hope: Ma kēia ala, ʻo ka heleuma wedge Through bolt i lawa ka nui e hoʻonui ai, no laila e hōʻoiaʻiʻo ʻia ka hana heleuma. He mea nui ia e hoʻomaʻemaʻe i nā lua ma ka puhi ʻana, ka palaki ʻana, a me nā mea ʻē aʻe ma hope o ka wili ʻana. ʻO nā puka i hoʻomaʻemaʻe ʻole ʻia e hōʻemi i ka hiki ke hāpai. ʻO ka ʻōpala i hana ʻia e ka wili ʻana e pili i ka hiki ke hoʻopaʻa maʻamau o ka heleuma wedge Ma o ka bolt i loko o ka lua.

Ua hōʻuluʻulu ʻia nā ʻano loiloi ʻehā o ka mea hana ma mua o ka haʻalele ʻana i ka hale hana:
1) Nā koi maikaʻi o ka hiʻohiʻona: ʻO ka nānā ʻana i ke ʻano o ka heleuma wedge ma o ka bolt mai ka hiʻohiʻona, ka heleuma wedge galvanized a me nā mea ʻē aʻe.
2) Ka nānā ʻana i ka mānoanoa o ka uhi ʻana o ka heleuma wedge ma o ka bolt
1. Measering tool method: ʻO ka nui i hoʻohana ʻia me ka micrometer, vernier caliper, plug gauge, etc.
2. Mākēneki ala: ʻO ke ʻano magnetic e ana i ka mānoanoa o ka papa uhi, ʻo ia ke ana hoʻopōʻino ʻole o ka papa hoʻopaʻapaʻa non-magnetic ma ka substrate magnetic me kahi ana mānoanoa magnetic.
3. Microscopy: Ua kapa ʻia ke ʻano microscopy ʻo ke ʻano metallographic, ʻo ia ka hoʻonui ʻana i nā mea paʻa i kālai ʻia ma kahi microscope metallographic me kahi maka micrometer e ana i ka mānoanoa o ka uhi ma ka ʻāpana.
4. Ke ano holo manawa
ʻO ke ʻano kahe o ka chronograph ka hoʻohana ʻana i kahi hopena e hiki ke hoʻoheheʻe i ka uhi ma ka ʻāpana ʻāpana o ka uhi, a helu i ka mānoanoa o ka uhi e like me ka manawa i koi ʻia no ka hoʻoheheʻe hapa. Aia kekahi ʻano plating spot, anode dissolution coulometric method a pēlā aku.
3) Ka nānā ʻana i ka ikaika adhesion o ka uhi ʻana o ka heleuma wedge ma o ka bolt
Nui nā ʻano e loiloi ai i ka pili ʻana o ka uhi ʻana i ka metala kumu, ʻo ka mea maʻamau kēia: friction polishing test; hōʻike ʻano faila; ʻano ʻōpala; ho'āʻo kūlou; ho'āʻo haʻalulu wela; ʻano extrusion.
4) Wedge heleuma Ma o ka bolt coating corrosion test
ʻO nā ʻano hoʻāʻo corrosion coating ʻo ia ka: hōʻike hōʻike lewa; ho'āʻo hoʻoheheʻe paʻakai kūʻokoʻa (NSS test); ho'āʻo paʻakai acetic acid (ASS test), copper accelerated acetic acid salt spray test (CASS test); a me ka corrosion paste corrosion ho'āʻo (CORR test) a me ka hoʻonā wahi hoʻāʻo corrosion; ho'āʻo kaiapuni, hoʻāʻo corrosion inter-immersion, etc.
