Mhedzisiro yeChamfer paPDC Cutters

PDC (Polycrystalline diamond compact) vanocheka vanoita basa rakakosha mukuita kwePDC bits mumafuta & gasi kuchera. Izvo zvakakosha kuti udzidze maitiro ekupwanya kwedombo kwePDC bits kubata nemaitiro akaoma, kunyanya kana matsime akareba uye akaomarara.

Pakati pezvinhu zvese zvinopesvedzera kugona kwekucheka, chamfer iri nyore kufuratirwa muzvidzidzo zveoretical uye zvekuedza.

Chamfer inzira yekuchinja pakati pezviso zviviri zvechinhu. Iwo maPDC cutters anowanzo ane chamfer zvese pazasi uye diamond layer.

Mukati memakore ekuma1990, tekinoroji yechamfering yakatanga kushandiswa zvakanyanya paPDC cutters, uye tekinoroji yakawanda-chamfering yakagamuchirwa muchimiro chepatenti mu1995. kuvandudzwa ne100%. Baker Hughes kambani yakabudirira kushandisa kaviri chamfer tekinoroji pamazino mumakore achangopfuura.

Iyo yakapetwa kaviri-chamfer PDC cutter tekinoroji nyowani inosanganisa yekutanga chamfer ine yechipiri mupendero, ichigonesa yakakura tsoka kudhirowa pasina kukanganisa mwero wekupinda (ROP). Kubva 2013, anopfuura chiuru nemazana mashanu anomhanya nemabhiti achishandisa kaviri-chamfer tekinoroji akaitwa muOklahoma. Iyo yakagomara nyika yakavandudzwa zvakanyanya, zvichikonzera kudzikiswa kwemhete, kubuda kwepakati, uye kumwe kukuvadza zvishoma.

Chamfering polycrystalline diamond compact (PDC) vanocheka vane mhedzisiro yakanaka pakusimba kwemupendero uye hupenyu hurefu hwese. Iyi pfungwa haina kuchinja kwemakumi emakore akati wandei kubva pakaunzwa chamfered PDC cutters. Tsvagiridzo zhinji dzakaitwa neimwe shanduko kune chamfer urefu kana chamfer angle kana neakasanganiswa egeometries.

Zvakaonekwa kuti kona diki inoreva yakakwira ROP asi yakawedzera tsika yekucheka uye kukuvadza kukuvadza pane kona hombe. Kona hombe inoreva kucheka kwakasimba asi kuderera ROP. Iko kukosha kwekona kunofanirwa kuvandudzwa maererano nemhando dzemaumbirwo akajairwa kuti aboore.

Kune mutengi, iyo yakagadziridzwa yekucheka tekinoroji yakakonzera kukosha kwakakosha kuchengetedza uye kuwedzera kuvimba muhupenyu hwematurusi, ichigonesa kutsungirira kukuru uye kusimba. Pakupedzisira, tekinoroji nyowani yekucheka inogonesa mitengo yakaderera yekuchera uye inovhura miganho yekuchera yaimbove isingaite.

Kugamuchirwa kuti utiwane nePDC cutters, dual-chamfer PDC cutters iripo.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
