Isixhobo sokusika i-core barrel ingaba yi-Bullet Teeth okanye i-Roller bit ngokuxhomekeke kumandla elitye elinzima.Isebenzisa umgaqo ofanayo wokugaya we-core barrel.Phambi kokuba undoqo welitye uphakanyiswe (ukhutshiwe), indlela yokomba iyafana.Xa ukugaya kugqityiwe, isiseko samatye siya kukhutshwa kunye nesi sixhobo.
Ubume bombhobho weCore
1) Ngomsebenzi wokuthintela iingozi ezimbini, umgqomo ongundoqo uxhotyiswe ngesixhobo sokuthintela ukujikeleza kunye nekhebula lokuthintela ingozi.Emva kokuba i-rotary shaft iphukile, i-barrel engundoqo ayiyi kuwela emngxunyeni
2) Cwangcisa isixhobo sobude bomda, xa kusomba ilitye eliqinileyo, akuyi kubangela ukuba undoqo unxibe kwaye utshabalalise indlela ephezulu ngenxa yokomba ixesha elide (undoqo wamatye omde)
3) Isixhobo sentwasahlobo yoxinzelelo, Esi sixhobo siqinisekisa ukuba iiflaps ezimbini zebhakethi zolulelwe ukuya kuthi ga kwinqanaba eliphezulu xa umbhobho ongundoqo udityaniswe emngxunyeni okanye ngexesha lokugaya, kwaye awuyi kuthuthumela ngenxa ye-jitter ye-drill rod, ukuze ikwazi. thintela umbindi welitye ekubeni ucudiswe phakathi kweflap yebhakethi kunye nodonga lombhobho ongundoqo, kwaye ubangele ukuba kuphuke iiflephu zamabhakethi.
4)Lo mgqomo we-Core ungasetyenziswa kungekuphela kwilitye eliqinileyo kodwa nakwizinto ezenziwe ngepumice ezinobubanzi begrabile obungaphezulu kwe-250mm.
Iinkqubo zokuqhuba i-Core Barrel
1) Ngaphambi kokuba uqhube umbhobho ongundoqo, ukuguquguquka kwendlela kufuneka kuhlolwe kwi-orifice.
2)Ieflaphu zamabhakethi mazingene emngxunyeni xa zoluliwe ngokupheleleyo.
I-3) Ukugaya kokuqala akukwazi ukunyanzeliswa, kwaye emva koko kugxininiswe ngokuthe ngcembe emva kokuba i-backdrilling izinzileyo.Ngeli xesha, i-core barrel akufuneki ibonakale ngathi iyatsiba (ushukuma unyuke usehla).
4) Ukuba i-countersining okanye ukugrumba okubambekayo kwenzeka ngexesha lokomba, yeka ukucinezela kwaye ungasebenzisi ukuguqula ukomba.
I-5) Ngexesha lokugaya, kwafunyaniswa ukuba ukuchasana nokubulala ngokukhawuleza kwanda.Ngeli xesha, kunokugwetywa kwangaphambili ukuba i-core yaphukile, kwaye inokutshintshwa ngamaxesha ama-2 ukuya kwe-3, kwaye i-barrel engundoqo inokuphakanyiswa.
I-6) Ngethuba lenkqubo yokugaya, ukulahlekelwa kwengcinezelo ngokukhawuleza kufunyenwe, oko kukuthi, akukho ukuchasana xa ujika.Kufuneka uyeke ukugrumba ngokukhawuleza kwaye ukhangele ukukhusela i-shaft ejikelezayo ukuba ingaphumi.
