Chidziwitso chachidule cha PDC drill bit
Zobowola za diamondi za Polycrystalline compact (PDC) zimapangidwa ndi zodula za diamondi zopangidwa ndi chitsulo kapena matrix body material.PDC zobowola zasintha kwambiri pobowola mosiyanasiyana komanso kuthekera kolowera kwambiri (ROP).

PDC Bits adapangidwa ndikupangidwa motere:

§Matrix - thupi pang'ono

§Zida zachitsulo

MATRIX-THUPI
Matrix ndi chinthu cholimba kwambiri komanso chosasunthika chomwe chimakhala ndi njere za tungsten carbide zomangika ndizitsulo zofewa, zolimba, zomangira zitsulo. Imasamva kukokoloka kuposa chitsulo. Amakondedwa m'matope obowola olimba kwambiri.

Ubwino-
1. Matrix ndiyabwino ngati chinthu chocheperako pamwamba pa chitsulo chifukwa kulimba kwake sikumamva kugwa komanso kukokoloka.
2. Imatha kupirira katundu wothinana kwambiri.
3. Pa ma bits okhala ndi diamondi, matrix-body build angagwiritsidwe ntchito.

Zoyipa-
1. Poyerekeza ndi chitsulo, ili ndi mphamvu yocheperako potsegula.
2. Kuchepa kwamphamvu kwa matrix kumachepetsa mbali zina za matrix-bit, monga kutalika kwa tsamba.

ZOCHITIKA-THUPI
Chitsulo ndi chosiyana kwambiri ndi matrix. Zitsulo zachitsulo nthawi zambiri zimakondedwa kuti zikhale zofewa komanso zosapsa komanso kukula kwa dzenje lalikulu. Kuchepetsa kukokoloka kwa thupi, tinthu tating'onoting'ono timakhala tolimba ndi zotchingira zomwe sizitha kukokoloka ndipo nthawi zina zimalandila mankhwala oletsa kupiringa pamiyala yomata ngati shales.

Ubwino-
1. Chitsulo ndi chodumphira, cholimba, ndipo chimatha kupirira katundu wambiri.
2. Imatha kupirira kuchulukirachulukira, koma ndi yofewa ndipo, popanda zodzitetezera, imatha kulephera msanga chifukwa cha zilonda ndi kukokoloka.
3. Chifukwa cha zinthu zachitsulo, ma profiles ovuta kwambiri ndi ma hydraulic designs ndizotheka ndipo n'zosavuta kupanga pamakina ophera amitundu yambiri, olamulidwa ndi manambala apakompyuta.

Zoyipa-
1. Chitsulo chimalimbana ndi kukokoloka pang'ono poyerekeza ndi matrix, motero, chitha kuvalidwa ndi madzi abrasive.


PDC bits kubowola makamaka ndi kumeta ubweya. Mphamvu yolowera yoyima kuchokera pa kulemera kwake koyikidwa pa biti ndi mphamvu yopingasa kuchokera pa tebulo lozungulira imatumizidwa ku zodula. Mphamvu yotsatiridwayo imatanthawuza ndege yokankhira kwa wodulayo. Zodulidwazo zimametedwa poyambira pomwe zimatengera mphamvu ya thanthwe.

Mitundu yambiri yogwiritsira ntchito ma bits a PDC imafuna luso lapadera la PDC cutter kuti mupeze ntchito yoboola kwambiri pa ntchito iliyonse. The Optimal cutter portfolio idzakulitsa magwiridwe antchito pazovuta zilizonse zoboola.
