PDC CONICAL CUTERS FOR HARD ROCK DILLING

Kuuya kwePolycrystalline Diamond Compact (PDC) cutter pakati pemakore ekuma1970 kwakatanga kufamba zvishoma nezvishoma kubva kune roller cone bit kusvika kune shear cutter bit. Vanhu vanoda zvose zvinocheka uye zvimedu zvinogona kugara kwenguva yakareba. Basa rakawanda rakaitwa pakuvandudza maumbirwo edhaimani, kugadzikana kwekupisa, kusimba kwechimiro, uye yekucheka geometry nechinangwa chese chekuwedzera maitiro uye kuramba abrasion. Iwo maPDC conical cutters anoratidzwa kuve ane mashandiro arinani mukuchera dombo rakaoma pane akajairwa shear PDC cutters.

Impact resistance

Kuramba kwekuita kwePDC cutters kwakaedzwa uchishandisa marabhoritari yekudonha bvunzo muchina. Kudonhedza bvunzo kwakaitwa paPDC pamakona ekukanganisa pakati pe17 degrees uye yakatwasuka. Zvakajairwa PDC shear cutters dzakatariswa pagumi madhigirii kubva kundege yechiso. Kuyedzwa kwakaratidza kuti Conical PDC cutter yaive ne 4 kusvika 9 nguva yekupikisa kweakaenzana saizi yekucheka shear kana yakadonhedzwa pane WC chinangwa. Iyo PDC conical cutter inonyanya kusimba kune kukanganisa kurodha kunoonekwa pane zvishoma munzvimbo yepasi-gomba.

VTL Testing

Kucheka pane cylindrical log yematombo ematombo pane yakanyatso shandiswa lathe ndiyo yakajairika indasitiri nzira yekumhanyisa kukurumidza kupfeka kana abrasion bvunzo paPDC cutters. Muchiitiko ichi, Vertical Turret Lathe yakashandiswa, kutenderedza slab yeGranite ine simba rekumanikidza. Chigadziko chinobata PDC uye chinobvumira mucheki kuunzwa padombo rinotenderera, risina kuvharwa. Iyo Computer Numerical Control (CNC) mudziyo unodzora kudzika kwekucheka, kutenderera kumhanya, mutsara kumhanya, uye chiyero chekudya.

Pfeka kuramba.

Mushure mePDC kucheka giraniti kwenguva yakati rebei, tinogona kuwana chiyero chekupfeka nekuyera kuti mangani maremu akarasika. Pane kurasikirwa kukuru pakati pePDC cutters negranite. Iyo yakakwirira iyo reshiyo iri, iyo inowedzera kupfeka kuramba iyo PDC cutters ichave.

Iyo PDC conical cutter inoratidzira yakanyanya kukwirisa abrasion kuramba uye inobudirira kucheka matombo akaomarara asina kucherechedzwa kupfeka, iyo inomiririra danho rakakosha kune chinangwa chehupenyu hurefu mabhiti ekuumbwa kwakaoma munzvimbo dzinopisa.

PaZZBETTER, tinogona kupa marudzi akasiyana ePDC cutters

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.
