Ukusebenza kwabasiki be-PDC

Ucwaningo nokuthuthukiswa kwabasiki be-PDC kwathuthukiswa emazweni amaningi ngeminyaka yawo-1970. Ummeleli "yi-stratapax" yenkampani ye-G.E, i-"syndrill" yenkampani yakwa-DeBeers, kanye ne-"Claw Cutter" ka-Sandvik.

Ukusebenza kwabasiki be-PDC abangenhla, akunandaba ukumelana nokugqokwa, ukuqina komthelela, noma ukuzinza kwe-thermal, konke kumelele izinga eliphezulu lomhlaba ngaleso sikhathi.

Ukusebenza komsiki we-PDC ikakhulukazi kubhekise ezinkomba ezingezansi:

1. Ukumelana nokugqoka (okubuye kwaziwe ngokuthi isilinganiso sokugqoka),

2. Ukuqina okungahambisani nomthelela (joule),

3. Ukuqina kokushisa

Ngemuva kwesikhathi eside sokuhlolwa komsiki we-PDC, sithole izinga labasiki be-PDC ezweni lethu linje ngezansi:

Maphakathi nawo-1990 kuya ku-2003: ukumelana nokugqoka kungu-8 kuya ku-120,000 (10 kuya ku-180,000 phesheya);

Ukuqina komthelela kungu-200 ~ 400 j (ngaphezu kuka-400 j phesheya).

Ushintsho ekuzinzeni kwe-thermal luwukuthi: ngemva kokucwilisa ku-750 ° C (ngaphansi kwezimo zokunciphisa), isilinganiso se-Wear siboniswa ukuthi sikhuphuke ngo-5% kuya ku-20% kwabanye abakhiqizi basekhaya, futhi ukuqina komthelela akunalo ushintsho olukhulu. Abanye abakhiqizi benqabile isilinganiso sokugqoka kanye nokuqina okulwa nomthelela.

Ukufingqa, ubulukhuni, ukumelana nokuguga, ukuqina komthelela, kanye nokuzinza okushisayo kwabasiki bezwe bethu be-PDC sekusondele futhi kwafinyelela ezingeni elithuthukisiwe lamazwe ngamazwe, kwabeka isisekelo sokuqhubeka nokubhoboza amatshe aqinile aphakathi nabasiki be-PDC.

Sibiza i-PDC cutter ngobulukhuni obuphezulu, ukumelana nokugqokwa okuphezulu, ukuqina komthelela omkhulu, kanye nokuzinza okuphezulu kokushisa izisiki ezine ze-PDC eziphezulu. Ukubhoboza ngezinqamuli ze-PDC zekhwalithi ephezulu kuzothuthukisa intuthuko ebanzi yamaphrojekthi okumba

Izinzuzo zokubhoboza amatshe athambile ukuya kokuqina okumaphakathi, ikakhulukazi amatshe aqinile, ngokusebenzisa i-drill bit eyinhlanganisela yilezi:

1. Ukusebenza kahle kokuchotshozwa kwamadwala kuba ngcono kakhulu

2. Ukusebenza kahle okuphezulu nokunciphisa isikhathi sokwakha

3. Khuthaza ukuvuselelwa kwemishini yokumba.

4. Ukusetshenziswa kwekhwalithi ephezulu ye-PDC cutters kukhuthaza ukuguqulwa kwesakhiwo sebhithi yedayimane kanye nokwakhiwa kwemingcele ye-hydraulic.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
