Iqhosha lePDC lokukhetha iDayimane

Iikhethi zedayimani zenziwe ngeqhosha lePDC kunye nomzimba wentsimbi. Iincinci zedayimane ziboshwe kwi-matrix yensimbi usebenzisa inkqubo yoxinzelelo oluphezulu kunye nobushushu obuphezulu. Le nkqubo idala isixhobo esomeleleyo kunye nesigxina esibizwa ngokuba yi-PDC iqhosha elinokumelana neemeko ezinzima xa usebenza.

Ukusetyenziswa kwedayimani pick:

Ukusetyenziswa kokukhethwa kwedayimani akuphelelanga kwishishini lemigodi. Zikwasetyenziswa nakwishishini lokwakha ukugrumba ikhonkrithi kunye nezinye izinto ezinzima. Iipeki zedayimani zikwasetyenziswa kwishishini le-oyile nerhasi ukugrumba kwiindlela zamatye aqinileyo ukufikelela koovimba be-oyile nerhasi.

Ukuchongwa kwedayimani sisixhobo esibalulekileyo kwishishini lemigodi. Zisetyenziselwa ukukhupha iiminerali kunye neentsimbi kuqweqwe lomhlaba. I-diamond pick yenziwe nge-diamond-tipped drill bit encanyathiselwe kwintonga yokubhola. Incam yedayimani yeyona nto inzima emhlabeni, iyenza ilungele ukugrumba amatye aqinileyo.

Ukukhethwa kwedayimani bubuchwephesha obuguqulayo obutshintshe ishishini lemigodi yamalahle. Ukumbiwa kwamalahle ngumsebenzi onzima noyingozi ofuna izixhobo ezikhethekileyo kunye nezixhobo. Iikhethi zendabuko ezisetyenziselwa ukumbiwa kwamalahle zenziwe ngentsimbi kwaye zinokuqina okulinganiselwe. Nangona kunjalo, ukuchongwa kwedayimani kubonakalise ukuba kusebenza ngakumbi kwaye kunendleko ekusebenzeni kwemigodi yamalahle.

Izinto ezilungileyo zokukhetha idayimani:

Enye yeenzuzo eziphambili zokukhetha idayimani kubomi babo obude. I-diamond picks ingahlala ukuya kumaxesha angama-20 ixesha elide kunezikhethi zensimbi zendabuko. Oku kuthetha ukuba iinkampani zemigodi yamalahle zinokonga imali kwiindleko zokutshintsha nokunciphisa ixesha lokungasebenzi ngenxa yokusilela kwezixhobo. Ukongezelela, iikhethi zedayimane zifuna ukugcinwa okuncinci kuneentsimbi zensimbi, ezinciphisa ngakumbi iindleko kunye nokwandisa imveliso.

Enye inzuzo yokukhethwa kwedayimani kukukwazi kwabo ukunqumla kwiindlela zamatye aqinileyo. Imithungo yamalahle idla ngokufumaneka kulwakhiwo lwamatye ekunzima ukungena ngalo ngeepiki zentsimbi zesintu. Izixhobo zedayimani ziyakwazi ukunqumla ezi zakhiwo ngokulula, ezinciphisa ixesha kunye nomzamo ofunekayo wokukhupha amalahle.

Ukuchongwa kwedayimani kukwabonelela ngokhuseleko oluphuculweyo kubasebenzi basezimayini zamalahle. Izipikili zentsimbi zemveli zinokuqhekeka okanye ziqhekeke ngexesha lokusetyenziswa, ezinokubangela ukulimala kakhulu kwabasebenzi basezimayini. Izixhobo zedayimani azinakwenzeka ukuba ziqhekeze okanye ziqhekeke, okunciphisa umngcipheko wokulimala kwabasebenzi basezimayini.

Ukuchongwa kwedayimani kuyatshintsha kushishino lwemigodi yamalahle. Banikezela ngokuphucula ukusebenza kakuhle, ukuphumelela kweendleko, ukuqina, kunye nokhuseleko xa kuthelekiswa neekhethi zensimbi zendabuko. Iinkampani zemigodi yamalahle ezenza utyalo-mali kwiikhethi zedayimani zinokulindela ukubona ukuphuculwa okubalulekileyo kwimveliso kunye nenzuzo.

Iqhosha lePDC lokuchola idayimani:

Ukuqaliswa kweqhosha le-Polycrystalline Diamond Compact (PDC) liye laguqula ukusebenza kakuhle kunye nokusebenza kweekhethi zedayimani. Singathanda ukwenza intshayelelo emfutshane malunga neengenelo kunye neenzuzo zokubandakanya amaqhosha ePDC kwizichotho zedayimani, siqaqambisa ifuthe lazo kwimveliso, ukusebenza kakuhle kweendleko, kunye nokusebenza ngokubanzi.
