Imbali emfutshane yePDC Cutters

I-PDC, okanye i-polycrystalline diamond compact, abasiki baye baba ngumtshintshi-mdlalo kushishino lokomba. Ezi zixhobo zokusika ziguqule iteknoloji yokugaya ngokunyusa ukusebenza kakuhle kunye nokunciphisa iindleko. Kodwa bavela phi abasiki bePDC, kwaye baye baduma njani?

Imbali yabasiki bePDC yaqala ngeminyaka yoo-1950 xa iidayimani zokwenziwa zaqala ukuphuhliswa. Ezi dayimani zaveliswa ngokubeka igraphite kuxinzelelo oluphezulu kunye namaqondo obushushu, ukwenza izinto ezazinzima kunedayimane yendalo. Iidayimani zokwenziwa zakhawuleza zaduma kwizicelo zemizi-mveliso, kuquka nokugrumba.

Noko ke, ukusebenzisa iidayimani zokwenziwa xa kusembiwa kwakulucelomngeni. Iidayimani zihlala ziqhekeza okanye ziqhawule kwisixhobo, zinciphisa ukusebenza kwazo kwaye zifuna ukutshintshwa rhoqo. Ukujongana nale ngxaki, abaphandi baqala ukuzama ukudibanisa iidayimani zokwenziwa nezinye izinto, ezifana ne-tungsten carbide, ukwenza isixhobo sokusika esomelele ngakumbi nesisebenzayo.

Ngeminyaka yee-1970, abasiki bokuqala bePDC baphuhliswa, bequka umaleko wedayimane obotshelelwe kwi-tungsten carbide substrate. Aba basiki baqale basetyenziswa kwishishini lemigodi, kodwa izibonelelo zabo zakhawuleza zabonakala kwizicelo zokomba ioyile nerhasi. Abasiki bePDC banikezela ngokugrumba ngokukhawuleza nangempumelelo, ukunciphisa iindleko kunye nokwandisa imveliso.

Njengoko itekhnoloji iphucuka, abasiki bePDC baye baba phambili ngakumbi, ngoyilo olutsha kunye nezixhobo zokwandisa ukuqina kwazo kunye nokuguquguquka kwazo. Namhlanje, abasiki bePDC basetyenziswa kuluhlu olubanzi lwezicelo zokomba, kubandakanya ukugrumba i-geothermal, imigodi, ukwakhiwa, kunye nokunye.

Ukusetyenziswa kwee-PDC cutters kukwakhokelele kwinkqubela phambili kubuchule bokomba, obufana nokugrumba okuthe tyaba kunye nokugrumba okuya ngakulo. Obu buchule benziwe bunokwenzeka ngokunyuka kokusebenza kunye nokuqina kwee-PDC cutters, ukuvumela ukugrumba okuchanekileyo kunye nokulawulwayo.

Ukuqukumbela, abasiki bePDC banembali etyebileyo esukela emva kuphuhliso lwedayimani zokwenziwa ngeminyaka yoo-1950. Ukuvela kwabo kunye nophuhliso kukhokelele kwinkqubela phambili ebalulekileyo kwitekhnoloji yokomba, ukuphucula ukusebenza kakuhle, ukunciphisa iindleko, kunye nokwandisa uluhlu lwezicelo. Njengoko imfuno yokomba okukhawulezayo nangaphezulu iqhubeka ikhula, kucacile ukuba abasiki bePDC baya kuhlala beyinxalenye ebalulekileyo kushishino lokomba.
