ʻO ka hana o nā meaʻoki PDC

Ua hoʻomohala ʻia ka noiʻi a me ka hoʻomohala ʻana i nā mea ʻoki PDC ma nā ʻāina he nui i ka makahiki 1970. ʻO ka ʻelele ka "stratapax" na ka hui G.E, ʻO ka "syndrill" na ka hui DeBeers, a me ka "Claw Cutter" na Sandvik.

ʻO ka hana ʻana o nā mea ʻoki PDC ma luna, ʻaʻohe mea i ke kūpaʻa ʻana, ka paʻakikī o ka hopena, a i ʻole ke kūpaʻa wela, e hōʻike ana i ka pae kiʻekiʻe o ka honua i kēlā manawa.

ʻO ka hana o ka mea ʻoki PDC e pili ana i nā hōʻailona ma lalo nei:

1. Wear resistance (ʻike pū ʻia ʻo ka ratio ʻaʻahu),

2. ʻO ka paʻakikī anti-impact (joule),

3. Paʻa wela

Ma hope o ka manawa nui o nā hoʻokolohua no ka ʻokiʻoki PDC, ʻike mākou i ke kiʻekiʻe o nā mea ʻoki PDC ma ko mākou ʻāina e like me lalo:

ʻO ka waena o 1990s a 2003: ʻo ke kūpaʻa ʻaʻahu he 8 a 120,000 (10 a 180,000 ma waho);

ʻO ka paʻakikī o ka hopena he 200 ~ 400 j (ʻoi aku ma mua o 400 j ma waho).

ʻO ka hoʻololi ʻana i ke kūpaʻa wela: ma hope o ka sintering ma 750 ° C (ma lalo o nā kūlana hoʻemi), hōʻike ʻia ka piʻi ʻana o ka Wear ratio e 5% a 20% no kekahi mau mea hana hale, a ʻaʻohe loli nui ka paʻakikī o ka hopena. Ua hōʻole kekahi mau mea hana i ka lākiō lole a me ka paʻakikī anti-impact.

I ka hōʻuluʻulu ʻana, ua hoʻokokoke ka paʻakikī, ke kūpaʻa ʻana, ka paʻakikī o ka hopena, a me ke kūpaʻa wela o nā mea ʻoki PDC o ko mākou ʻāina a hiki i ka pae kiʻekiʻe o ka honua, e kau ana i kumu no ka ʻeli hou ʻana i nā pōhaku waena me nā mea ʻoki PDC.

Kāhea mākou i ka mea ʻoki PDC me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe, ka paʻakikī o ka hopena kiʻekiʻe, a me ke kūpaʻa wela kiʻekiʻe nā ʻokiʻoki PDC ʻehā. ʻO ka wili ʻana me nā mea ʻoki PDC kiʻekiʻe e alakaʻi i ka hoʻomohala piha ʻana o nā papahana wili

ʻO nā pōmaikaʻi o ka ʻeli ʻana i nā pōhaku palupalu a paʻakikī, ʻoi aku ka paʻa o nā pōhaku paʻa, me ka hoʻohana ʻana i kahi drill bit:

1. Hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka wāwahi pōhaku

2. ʻO ke kūlana kiʻekiʻe a hoʻopōkole i ka manawa hana

3. Hoʻolaha i ka hana hou ʻana i nā mea hana wili.

4. ʻO ka hoʻohanaʻana i nā meaʻoki PDC kiʻekiʻe e hoʻoikaika i ka hoʻololiʻana i keʻano o ka bit diamond a me ka hoʻolālāʻana i nā palena hydraulic.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
