Kuchita kwa ocheka a PDC

Kafukufuku ndi chitukuko cha ocheka a PDC adapangidwa m'maiko ambiri m'ma 1970. Woyimira ndi "stratapax" ndi kampani ya G.E, The "syndrill" ndi kampani ya DeBeers, ndi "Claw Cutter" ndi Sandvik.

Magwiridwe a odula a PDC omwe ali pamwambawa, posatengera kukana kuvala, kulimba kwamphamvu, kapena kukhazikika kwa kutentha, zonse zikuyimira dziko lapansi panthawiyo.

Magwiridwe a PDC cutter makamaka amatanthauza zizindikiro zotsatirazi:

1. Kukana kuvala (kotchedwanso wear ratio),

2. Anti-impact toughness (joule),

3. Kukhazikika kwa kutentha

Pambuyo pakuyesa kwanthawi yayitali kwa wodula wa PDC, tidapeza kuti odula a PDC mdziko lathu ali pansipa:

Pakati pa 1990s mpaka 2003: kuvala kukana ndi 8 mpaka 120,000 (10 mpaka 180,000 kunja);

Kulimba kwamphamvu ndi 200 ~ 400 j (kuposa 400 j kunja).

Kusintha kwa kukhazikika kwa kutentha ndi: pambuyo pozizira pa 750 ° C (pansi pa mikhalidwe yochepetsera), chiwerengero cha Wear chikuwonetsedwa kukwera ndi 5% mpaka 20% kwa opanga ena apakhomo, ndipo kuuma kwamphamvu sikukhala ndi kusintha kwakukulu. Opanga ena adakana pazovala komanso kulimba kwa anti-impact.

Pomaliza, kulimba, kukana kuvala, kulimba kwamphamvu, ndi kukhazikika kwa kutentha kwa ocheka a PDC a dziko lathu ayandikira ndikufika pamlingo wapamwamba wapadziko lonse lapansi, kuyala maziko obowolanso miyala yolimba yapakati ndi odula a PDC.

Timatcha chodula cha PDC cholimba kwambiri, kukana kuvala kwambiri, kulimba kwamphamvu, komanso kukhazikika kwamafuta ambiri odula anayi a PDC. Kubowola ndi odula apamwamba kwambiri a PDC kudzayendetsa chitukuko chokwanira cha ntchito zoboola

Ubwino wakubowola miyala yofewa kapena yolimba, makamaka yolimba, pogwiritsa ntchito chobowola chophatikizika ndi:

1. Kuchita bwino kwa kuphwanya miyala kumakhala bwino kwambiri

2. Kuchita bwino kwambiri ndikufupikitsa nthawi yomanga

3. Limbikitsani kukonzanso kwa zida zoboola.

4. Kugwiritsa ntchito odula apamwamba a PDC kumalimbikitsa kusintha kwa kapangidwe ka diamondi kakang'ono ndi mapangidwe a hydraulic parameters.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
