Zvinhu Zvaunofanira Kuziva Nezve PDC Drill Bits

Polycrystalline diamond compact (PDC) ndechimwe chezvinhu zvakaoma pasi rose, iyo yakaoma kupfuura tungsten carbide. Kunyangwe PDC ine kuoma kwakakwana kwekushandisa muindasitiri yemazuva ano, inodhura zvakanyanya. Tungsten carbide iri nani pane PDC zvinhu zvehupfumi kana matombo asina kuoma. Asi PDC drill bits, hongu, zvine zvazvakanakira sezvo zvakakurumbira mukuvakwa kwemigodhi.

Chii chinonzi PDC drill bit?

Sezvatinoziva tese, tungsten carbide mabhatani anoshandiswa kupinza mukati memuviri wekubooresa kugadzira dhiri. PDC drill bits ine PDC cutters pavari. PDC cutters inogadzirwa ne tungsten carbide PDC substrates uye PDC zvidimbu pasi penzvimbo yekumanikidza kwakanyanya uye tembiricha yakanyanya. Kugadzirwa kwekutanga kwePDC drill bits kwakaonekwa muna 1976. Mushure mezvo, vanova vanozivikanwa zvikuru mumaindasitiri akawanda ekuchera.

PDC drill bit inogadzirwa sei?

PDC drill bit inobva ku tungsten carbide PDC substrates uye PDC layer. PDC substrates dzinobva kumhando yepamusoro tungsten carbide poda, inosangana nekusanganiswa, kugaya, kudzvanya, uye sintering. PDC substrates dzinofanirwa kusanganiswa nePDC layer. Iine catalyst yecobalt alloy pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya, iyo inogona kubatsira bond diamond uye carbide, iyo PDC cutter inogona kuoma uye yakasimba. Pavanotonhora pasi, tungsten carbide inodzika 2.5 nguva nekukurumidza kupfuura PDC layer. Pasi penzvimbo yekushisa kwepamusoro zvakare, maPDC cutters anozogadzirwa mumabhiti ekuchera.

Zvishandiso zvePDC drill bits

Mazuva ano, iyo PDC drill bits inowanzo shandiswa mumamiriro anotevera:

1. Geological exploration

Madhiri ePDC akakodzera kuongororwa geological pamatombo akapfava uye ari pakati nepakati nekuda kwekuoma kwazvo.

2. Pamunda wemarasha

Kana madhiri ePDC akaiswa panzvimbo yemarasha, akashandisa kuchera nekuchera musono wemarasha. Iyo PDC drill bits inoita hunyanzvi hwepamusoro.

3. Kuongorora peturu

PDC drill bits inogona zvakare kushandiswa pakuongorora peturu pakuchera munzvimbo dzemafuta negasi. Rudzi urwu rwePDC drill bit inogara ichidhura zvakanyanya.

Zvakanakira zvePDC drill bits

1. Kuramba kwepamusoro kune simba;

2. Kushanda kwenguva refu kweupenyu;

3. Haisi nyore kukuvadza kana kudonha;

4. Chengetedza mutengo wevatengi;

5. Kubudirira kwebasa repamusoro.

Kana iwe uchifarira PDC cutters uye uchida rumwe ruzivo uye ruzivo, unogona KUTITA NEI runhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji.
