Ubwino wa ma bits a PDC

Polycrystalline diamondi yaying'ono (PDC) ndi PDC kubowola bits adayambitsidwa pamsika kwazaka makumi angapo. Pa nthawi yaitali imeneyi,PDC cutter ndi PDC drill bit adakumana ndi zopinga zambiri m'zaka zawo zoyambirira, adakumananso ndi chitukuko chachikulu. Pang'onopang'ono koma pomaliza, ma bits a PDC pang'onopang'ono adalowa m'malo mwa ma cone ndikuwongolera mosalekeza mu chodula cha PDC, kukhazikika pang'ono, ndi kapangidwe kake ka hydraulic. Ma bits a PDC tsopano atenga zoposa 90% ya zojambula zonse padziko lapansi.

Kubowola kwa diamondi kumagwiritsidwa ntchito pafupifupi pazinthu zonse kuphatikiza pobowola mphamvu ya geothermal, migodi, chitsime chamadzi, kubowola gasi, ndi kubowola chitsime chamafuta.

Nawa maubwino ena a PDC bits.

1. Zotsika mtengo

Ma bits a PDC amatha kukhala okwera mtengo kwambiri. Mosiyanatmaricone pang'ono, palibe magawo osuntha pa PDC bit kuti atha. Ma diamondi opangidwa omwe akuyang'ana amatha kugwedezeka, koma chodula cha PDC chikhoza kuchotsedwa ndipo china chatsopano chikhoza kuikidwa m'malo mwake. Kumanganso PDC pang'ono nthawi zambiri kumakhala pafupifupi theka la mtengo wogula chatsopano.

2. Mlingo wa Kulowa

Ma bits a PDC, m'mapangidwe olondola, amakhala ndi kulowera kodabwitsa. Mapangidwe omwe PDC bits amachita bwino akuphatikizapo koma samangokhalira shale, miyala yamchere, mchenga, ndi dongo. Ma bits a PDC amatha kukhala paliponse mpaka 3-5 mwachangu kuposa ma tri-cone bits.

3. Kusunga Ndalama

Zida za PDC zimapulumutsa ndalama. Chifukwa ma PDC amabowola mwachangu kwambiri, pamakhala nthawi yambiri yosungidwa. Nthawi yosungidwa imalola wobowola kuti amalize ntchito zambiri munthawi yochepa. Pantchito yaying'ono, imasungidwa maola ndi masiku. Pa ntchito yokulirapo, imasungidwa masabata ndi miyezi. Ubwino womaliza ntchitoyo mwachangu ungaphatikizepo kupulumutsa pa ola la anthu ndi mafuta, kukumana ndi/kapena kupyola masiku omalizira, ndi kugwiritsa ntchito zing'onozing'ono ndi zogula.

Ponseponse, pali zabwino zambiri pakubowola ndi ma PDC bits. Monga china chilichonse, ntchito yobowola ikusintha nthawi zonse. Kusintha kwaukadaulo ndi kubowola kungakhale chinthu chabwino. PDC bits zitha kukhala kusintha komwe kumapangitsa kusiyana kwa inu.
