1. Nā loina kumu no ke koho ʻana i ka hardfacing
l No ka ho'opa'a 'ana i ka 'a'ahu maika'i a me ka pale 'ana i nā mea paahana lalo e like me nā hui paipu drill, paipu wili kaumaha, a me nā kola wili. ʻAʻole pono e emi iho ka paʻakikī o ke kāʻei pale ʻaʻahu ma mua o HRC55.
l I ka wili ʻana i ka pahu, i mea e pale ai i ka pahu a hoʻemi i kona ʻaʻahu, pono ke kāʻei pale pale i koho ʻia i ka hana anti friction maikaʻi.
l He kaulike kūpono ʻepekema ma waena o ke kūpale ʻaʻahu a me ka emi ʻana o ka friction.
l 'O ka mea ma'amau, ua paipai 'ia e ho'ohana i ka hardfacing me ke 'ano "ho'oki'eki'e", 'a'ole i paipai 'ia e ho'ohana i ka hardfacing me ke 'ano "flat". Aia wale nō ke kaupalena ʻia ke anawaena o waho o ka hui paipu drill i mea e pale aku ai i ka hoʻopilikia ʻana i ke anawaena o loko o ka pahu pahu, ua ʻōlelo ʻia e hoʻohana i kahi kāʻei pale ʻaʻahu ʻano "paʻa". ʻAʻole hiki i kēlā me kēia ʻano o nā kāʻei pale ʻaʻahu i wili ʻia ma kēia ʻano ʻaʻole hiki ke hoʻohua i ka hopena pale pale ʻoi loa no ka mea ʻo ke anawaena o waho o ka hui paipu drill a me ke kāʻei pale ʻaʻahu i ka manawa like.
2. Nā kuhi hewa maʻamau i ke koho ʻana i ka hardfacing
Kuhihewa 1:ʻO ke kāʻei kūpaʻa kūʻokoʻa ʻo Tungsten carbide ʻo ia ke kāʻei kūpaʻa maikaʻi loa i hoʻohana ʻia e pale i nā koʻokoʻo drill
Ma hope o ka hoʻopaʻa ʻia ʻana o ke kāʻei kūʻokoʻa tungsten carbide ma luna o ka hui paipu drill, ʻo nā ʻāpana tungsten carbide ʻoi aku ka mea e ʻoki ai i ka ʻokiʻoki ʻana i ka pahu, e hopena i ka ʻaʻahu o ka pahu.
Nui nā hui aila ʻē aʻe i nā kūlana kūloko e pāpā ʻole i ka hoʻohana ʻana i ka tungsten carbide hardfacing. Ua pāpā kekahi mau ʻaila ʻaila i ka hoʻohana ʻana.
NS-1 maʻamau
Nā kūlana kūloko o P Oil Company ma UK
Kuhihewa 2: Ke koho ʻana i ke alo paʻakikī e ʻimi nui i ka hoʻohaʻahaʻa friction a kaumaha i ka pale ʻana i ka lole
l I mea e pale aku ai i ka casing a e hoemi i kona aahu, o ka imi nui ana i ka hana anti friction o ke kaei pale lole e kaumaha ana i kona pale lole.
ü He mea maʻalahi ke kāʻei ʻaʻahu a hiki ke hoʻopili pololei ʻia ma waena o ka hui paipu drill a me ka pahu a i ʻole ka luawai hoʻokumu. E like me ka mea i ʻike ʻia, ʻoi aku ka ʻoi aku o ka ʻaʻahu ma waena o ka hui ʻana o ka pahu drill a me ka casing a i ʻole ka hoʻokumu ʻana i ka luawai i ʻoi aku ka nui ma mua o ka hui pū ʻana o ka paipu drill me ke kāʻei paʻa paʻa, e hopena i ka ʻeha nui o ka pahu a me ka hiki ʻole o ka paipu drill. ma muli o ka ʻaʻahu nui loa.
ü Hoʻonui ke ola lawelawe pōkole o ka hardfacing i kā lākou mau kumukūʻai hoʻohana.
