Ithuluzi lokusika le-core barrel lingaba yi-Bullet Teeth noma i-Roller bit kuye ngamandla etshe eliqinile.Isebenzisa isimiso sokubhola esifanayo somphongolo owumgogodla.Ngaphambi kokuthi umgogodla wetshe uphakanyiswe (ukhishwe), indlela yokubhoboza iyafana.Lapho ukubhola sekuqediwe, umgogodla wetshe uzokhishwa ndawonye ngaleli thuluzi.
Ukwakheka komgqomo we-Core
1) Ngomsebenzi wokuvimbela izingozi ezimbili, umgqomo oyinhloko ufakwe idivayisi yokuvimbela i-twist-off kanye nekhebula lokuvimbela ingozi.Uma i-rotary shaft iphuka, umgqomo oyinhloko ngeke uwele emgodini
2) Setha idivayisi yobude bomkhawulo, lapho umba idwala eliqinile, ngeke kubangele ukuthi umgogodla uguge futhi ucekele phansi umshini ongaphezulu ngenxa yokubhoboza isikhathi eside (umgogodla wamatshe omude)
3) Ithuluzi lentwasahlobo yokucindezela, Lo mshini uqinisekisa ukuthi amabhakede amabili avuleka aze afinyelele phezulu lapho umgqomo oyinhloko ubhobozwa emgodini noma ngesikhathi sokumba, futhi ngeke kuthuthumele ngenxa ye-jitter ye-drill rod, ukuze ikwazi. vimbela umgogodla wetshe ukuthi ungacindezelwa phakathi kwebhakede lebhakede nodonga lomgqomo oyinhloko, futhi kubangele ukuphuka kwamabhakede.
4) Lo mgqomo we-Core ungasetshenziswa hhayi edwaleni eliqinile kuphela kodwa nasezimisweni ze-pumice ezinobubanzi betshe obungaphezu kuka-250mm.
Izinqubo zokusebenza zokumba i-Core Barrel
1) Ngaphambi kokusebenzisa umgqomo oyinhloko, ukuguquguquka komshini kufanele kuhlolwe endaweni ephuma emlonyeni.
2)Iziphepho zamabhakede kumele zingene embobeni uma zeluliwe ngokugcwele.
3)Ukubhoboza kokuqala akukwazi ukucindezelwa, bese kuthi kancane kancane kucindezelwe ngemuva kokuthi i-backdrilling izinzile.Ngalesi sikhathi, umgqomo oyinhloko akufanele ubonakale weqa (usuka phezulu naphansi).
4) Uma ukucwila noma ukumba okunamathelayo kwenzeka ngesikhathi sokumba, yeka ukucindezelwa futhi ungasebenzisi ukubhola okuhlanekezelwe.
I-5) Ngesikhathi sokumba, kwatholakala ukuthi ukumelana nokubulala kwanda ngokuzumayo.Ngalesi sikhathi, kungahlulelwa kuqala ukuthi umgogodla uphukile, futhi ungahlehliswa izikhathi ezi-2 kuya kwezi-3, futhi umgqomo oyinhloko ungaphakanyiswa.
I-6) Phakathi nenqubo yokumba, ukulahlekelwa kwengcindezi kungazelelwe kutholakala, okungukuthi, akukho ukumelana lapho uphenduka.Udinga ukuyeka ukubhoboza ngokushesha futhi uhlole ukuze uvimbele ukuphuka kwe-shaft ejikelezayo.
