API umzi-mveliso PDC Bit Bit for Under Reamer ukomba

BI iziko bit isetyenziselwa reaming umngxuma ezantsi, imodeli Nombolo uthanda 5 7/8″ * 7 1/2″ * 4 3/4″ okanye nje 5 7/8″ * 7 1/2″ njengoko idayamitha yesithathu i. ayibalulekanga.

I-5 7/8″ kukudlula kwidayamitha, 7 1/2″ yidayamitha yokubuyisela kwakhona, 4 3/4″ yidayamitha yebit engaphambili.

IMpuma Ekude yimizi-mveliso esebenza ngokugrumba, njenge-roller cone bit, i-tricone roller cone bits, i-tricone bits, i-HDD yokuvula umngxuma, i-Foundation roller cutters kwizicelo ezahlukeneyo.Usetyenziso olubandakanya indawo yeoli, irhasi yendalo, uphononongo lwejoloji, ukudinwa kwedriectional, imigodi, ukugrumba amanzi, i-HDD, ukwakhiwa kunye nesiseko.
Njengomzi-mveliso okhokelayo we-drill drill e-China, ukwandisa ubomi bokusebenza be-drill yinto esijolise kuyo.Sihlala sizama ukuphucula iibhithi kunye namazinga aphezulu okungena.Injongo yethu kukuthengisa umgangatho ophezulu kunye nexabiso eliphantsi.Umgangatho wokugaya impuma ekude kunye nobuchwepheshe kuya kukunceda ufezekise ngakumbi.
