PDC drill bits nozzles
Hoʻopuka Hoʻolaha
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 kihi o nā drill bits, hiki i nā nozzles carbide ke hoʻomaʻemaʻe i nā ʻāpana pōhaku ma lalo o ka luawai me ka wili. wai i nā kūlana hana o ke kaomi kiʻekiʻe, ka haʻalulu, ke one, a me ka slurry e hoʻopilikia ana i ka wā o ka ʻaila a me ke kinoea kūlohelohe.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 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 i nā ʻano like ʻole a me nā hui nui no ka hapa nui o nā noi wili iho-hole.Hoʻolālā ʻia kā mākou mau māka i hoʻāʻo ʻia no ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ke kūpaʻa ʻana i nā noi kaha 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.
