Thermal Effect paPDC Cutter

Zvave zvichizivikanwa kuti PDC bits inoshanda zvakanyanya kudarika roller cone bits, asi izvi zvinongoonekwa chete pakuchera matombo akapfava. Izvi zvinogona kunge zvakakonzerwa nekuti 50% yesimba rekuchera inogona kubviswa neakacheka akacheka. Pamusoro pekupfeka kunokonzerwa nekudyidzana pakati pedombo nekucheka, zvinopisa zvinopisa zvinogona kukurumidza kukurumidza chiyero icho mucheki achapfeka.

Kana kupisa kwemafuta kwakaregeredzwa, zvinogona kuguma nekupfeka zvishoma kungoita basa remutoro wakaiswa kune zvishoma uye chinhambwe chafambwa uchisangana nedombo. Sezvatinoziva, izvi hazvisizvo. Kupisa kwemafuta kune kukanganisa pachiyero chinopfekwa nebhiti.

Zvinonzi abrasive kupfeka simbi ane chokuita kuoma reshiyo abrasive zvinhu uye simbi. Kune mabrasives akapfava ane reshiyo isingasviki 1.2, chiyero chekupfeka chakaderera. Sezvo chiyero chekuomarara kwehukama chinodarika 1.2, chiyero chekupfeka chinowedzera zvakanyanya.

Kana uchitarisa quartz, iyo iri chero kubva pa20- 40% yematombo akawanda ematombo, kuoma kunotangira pakati pe9.8-11.3GPa uye iyo tungsten carbide i10-15GPa. Mitsara iyi inoguma nereshiyo inotangira pa0.65 kusvika 1.13, ichiisa hukama uhwu sechinyoro chinyoro. Kana tungsten carbide ichishandiswa kucheka matombo ari kana kuti pasi pe 350 oC, vanosangana nekupfeka kwakafanana nekweabrasive yakapfava sezvaitarisirwa.

Kana tembiricha yadarika 350 oC, kupfeka kunokwidziridzwa uye kunobatana zvirinani neiyo yakaoma abrasive. Kubva pane izvi, zvinogumiswa kuti kupfeka kunowedzera nekupisa. Kuderedza PDC kupfeka, zvingava zvinobatsira kudzora tembiricha yevanocheka.

Pakatanga ongororo yezvinopisa pakupfeka kwePDC, 750oC ndiyo yaive yakanyanya kuchengetedzeka tembiricha yekushandisa. Iyi tembiricha yakasimbiswa, nekuti pasi peiyi tembiricha microchipping yaive kupfeka kwakaonekwa pane cutter.

Pamusoro pe750 ℃ ​​yakazara madhaimani tsanga dzaibviswa kubva padhaimani layer uye painosvika tembiricha dziri pamusoro pe950 ℃ iyo tungsten carbide stud yakasangana nepurasitiki deformation. Kunzwisisa kwevanocheka uye PDC bit geometry inofanira kuva chaiyo kupa ruzivo rwakakwana paunenge uchiita sarudzo shoma.

Zzbetter inopa yemhando yepamusoro PDC cutter ine yakanaka kugadzikana kwekupisa. Chikwata chedu chinoshanda nesimba zvakanyanya kugadzira zvigadzirwa zvemhando yepamusoro. Tinotarisira kushandira bhizinesi rako.

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