PDC drill bits nozzles

ʻO ka PDC drill bits nozzles, e hōʻike ana i kahi ʻano maʻalahi, ikaika kiʻekiʻe, kūpaʻa ʻaʻahu kiʻekiʻe, a me ke kūpaʻa hopena kiʻekiʻe, ʻo ia nā hiʻohiʻona o PDC bit nozzle kekahi o nā ʻenehana hou ʻekolu o ka wili ʻana ma ka honua i nā makahiki 1980. Hōʻike ka hoʻohana ʻana i ke kahua he kūpono ka ʻeli ʻana i ka daimana no nā hana palupalu a me ka paʻakikī ma muli o ka maikaʻi o ke ola lōʻihi o ka lawelawe ʻana, ka liʻiliʻi o ka manawa hoʻomaha, a me ka ʻoi aku ka paʻa.

ʻO ka nozzle carbide cemented kekahi o nā mea koʻikoʻi no ka drill bit, tungsten carbide drill bit nozzle e pili ana i ka flush, cool, a lubricate i nā ʻōlelo aʻoaʻo o nā drill bits, hiki i nā nozzles carbide ke hoʻomaʻemaʻe i nā ʻāpana pōhaku i lalo me ka wai wili i nā kūlana hana o ke kiʻekiʻe kiʻekiʻe, vibration, one, a me ka slurry e pili ana i ka wā o ka aila a me ke kinoea maoli. Loaʻa i nā nozzles Carbide kahi hopena hoʻokaʻawale pōhaku hydraulic. He cylindrical ka nozzle maʻamau; hiki iā ia ke hana i ka puʻunaue kaulike ma luna o ka ʻili pōhaku.

Hoʻohana nui ʻia nā nozzles tungsten carbide no nā ʻoki ʻoki paʻa a me nā ʻāpana cone roller no ka wai anuanu a me ka holoi ʻana i ka lepo, e like me ka wili ʻana o ke kaiapuni honua, e koho mākou i nā kahe wai like ʻole a me nā nui o ka lua i ke ʻano o nā nozzles tungsten.

Nā ʻano o nā nozzles carbide

ʻElua ʻano nui o nā nozzles carbide no nā ʻāpana drill. ʻO kekahi me ka milo, a ʻo kekahi me ke kaula ʻole. Hoʻohana nui ʻia nā nozzles Carbide me ka ʻole o ka milo ma luna o ka ʻāpana wili, hoʻohana ʻia nā nozzles carbide me ke kaula i ka hapa nui o ka drill bit PDC. E like me ka ʻokoʻa hoʻohana ʻana i nā kīwī hāmeʻa, aia nā ʻano 6 o nā nozzles threaded no nā bits PDC:

1. Nā nozzles milo kea

2. Nā nozzles milo ʻano pua pua

3. Nā nozzles milo hexagonal waho

4. Nā nozzles lola hexagonal kūloko

5. ʻAno Y (3 slot/grooves) thread nozzles

6. nā nozzles drill bit a me nā nozzles fracturing.

Hiki iā Kedel Tool ke hana i nā ʻano lola nozzle no nā ʻāpana drill PDC ma ka metric a me ka milo imperial. ʻO ka lola koʻikoʻi aupuni hui pū ʻia, ka milo maikaʻi, a me nā milo kūikawā me ka pae pololei 3, ka pololei kiʻekiʻe loa ma ka maʻamau ʻAmelika. E like me kāu mau koi no ka carbide bit, hiki ke hoʻolālā ʻia me ka hoʻololi.

ʻAʻole hiki iā mākou ke hana wale i nā nozzles tungsten carbide maʻamau, akā hiki iā mākou ke hana i nā nozzles maʻamau e like me nā kiʻi a i ʻole nā palapala. Loaʻa nā nozzles ma kahi ākea o nā ʻano a me nā hui nui no ka hapa nui o nā noi wili i lalo. Hoʻolālā ʻia kā mākou mau māka i hoʻāʻo ʻia no ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka pale ʻana i nā noi kiʻekiʻe. Hiki iā mākou ke hoʻohui i ka papa waiwai tungsten carbide kūikawā no ʻoe. Loaʻa iā mākou ka ʻike e hana i nā ʻano like ʻole a me nā nui o nā nozzles alloy tungsten.
