PDC Cutter ya PDC Core Bit

PDC core bit imapangidwa ndi odula a PDC ndi thupi la matrix kapena thupi lachitsulo. PDC core bit ndiyabwino kugwiritsa ntchito ndi zida zobowola zamphamvu kwambiri zomwe zimagwira ntchito pa liwiro lotsika kwambiri. Koma moyo ndi malowedwe amatha kukhala abwinoko poyerekeza ndi ma bits okhala pamwamba.

PDC core bit ili ndi ma sintered polycrystalline-diamond studs pa thupi la matrix. Chodulira cha PDC chimakhala ndi tinthu tating'ono ta diamondi tambiri tomwe timasakanikirana ndi kuthamanga kwambiri komanso kutentha kwambiri. Pansi pa diamondi wosanjikiza uyu pali tungsten carbide stud yomwe imangiriridwa molunjika m'thupi. Mitundu iwiri ikuluikulu ya odula a PDC ilipo pa PDC core bit: kapangidwe kanyumba kokhazikika kapena dome. Odula a PDC amaikidwa pa korona ndipo amatha kutenga katundu wochuluka kwambiri komanso wometa ubweya wopangidwa pobowola. Pali pafupifupi khumi odula a PDC pa thupi la matrix, kutengera kukula kwa pachimake. Chokulirapo pang'ono ndi, kuchuluka kwa odula PDC pa izo.

PDC core bit ili ndi mabowo otulutsa kapena malo otseguka komanso chosinthika cha nozzle yokhazikika. Ma nozzles amafunikira chifukwa amapereka chipwirikiti kuyenda kwa jeti kudzera mu tizidutswa tating'onoting'ono kuti malo odulirawo akhale oyera.

Mapangidwe ambiri a miyala ya sedimentary monga shale, dolomite, laimu, ndi sandstone amagwiritsidwa ntchito mosavuta ndi PDC core bit. Pamapangidwe olimba kwambiri monga dolomite ndi laimu, matrix body PDC core bit amagwiritsidwa ntchito nthawi zambiri chifukwa amakana kuvala. Thupi lachitsulo PDC core bit nthawi zambiri limagwiritsidwa ntchito popanga zofewa ngati sandstone. Pachimake pang'ono amagwiritsa ntchito kumeta kapena kumeta pamene mukukumana ndi mapangidwe. Kuthamanga kwa core bit ndikokwera kwambiri kuposa ma rotary bits ena. Ma Hydraulics a PDC core bit ali ndi kapangidwe kamene kamapangitsa kuti dzenjelo likhale loyera komanso kuti tizigawo tapakati tizizizira, motero zimakulitsa moyo wautali.

Ngati mukufuna zodula za PDC ndipo mukufuna zambiri ndi zambiri, mutha KULAMBIRA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZENI MAIL pansi pa tsambali.
