PDC reamer (Polycrystalline Diamond Compact reamer) ndi chida chobowola mopingasa (HDD), chomwe chimagwiritsidwa ntchito kukulitsa mabowo oyendetsera mapaipi popanda kukumba pamwamba. Chili ndi zodulira za PDC zokhazikika, zomwe zimagwiritsidwa ntchito kwambiri m'mapulojekiti amagetsi am'mizinda, mafuta/gasi ndi owoloka mitsinje.
Zigawo zake zazikulu zikuphatikizapo zodulira za PDC zolimba kwambiri, thupi lachitsulo cholimba la chidutswa chimodzi (chiopsezo chochepa cha kulephera) ndi ma hydraulic ports (ochotsera ndi kuziziritsa zidutswazo). Imagwira ntchito pozungulira kuti ikule mabowo oyendetsera ndege mpaka kukula kwa mtunda womwe ulipo pambuyo pobowola oyendetsa.
- Kuchita bwino kwambiri: 30–60% mwachangu kuposa ma reamers achikhalidwe, zomwe zimapulumutsa nthawi ya polojekiti.
- Moyo wautali wa ntchito: Zipangizo zodulira za PDC sizimakhudzidwa ndi kusweka, zomwe zimachepetsa kusintha kwa zida.
- Yogwirizana ndi chilengedwe: Palibe malo okumba zinthu, yoyenera madera a m'mizinda.
- Yotsika mtengo: Yotsika mtengo wogwirira ntchito chifukwa cha nthawi yochepa yogwirira ntchito komanso ntchito yochepa.
Ntchito zodziwika bwino: Kuyika mapaipi mumzinda, mapulojekiti a HDD owoloka mitsinje/misewu. Chitsanzo cha nkhani: Chotsukira madzi chatsopano cha PDC chachepetsa nthawi yomanga ndi 40% mu projekiti ya mapaipi amadzi mumzinda, kupewa kutsekedwa kwa misewu.
