4 "5" 6" dth rauj DHD 340 350 khawm drilling ntsis
DTH ntsis yog lub cuab yeej txiav pob zeb.Sinodrills DTH ntsis yog ua los ntawm superior zoo alloy hlau uas yog tsim los ntawm Timken nyob rau hauv Teb Chaws Asmeskas Dhau li ntawd, tag nrho peb cov DTH me ntsis yog siv lub hom "Element Six" TC carbide uas muab (TC nyees khawm) rau Boart Longyear.Ntxiv nrog rau kev tsim khoom siv thev naus laus zis ua rau peb DTH me ntsis nrog ntau dua thiab txhim khu kev qha zoo.
Lub ntsej muag sib txawv ua rau DTH ntsis yog haum rau ntau yam pob zeb.
Lub ntsej muag tiaj tus: Qhov no yog qhov tsim qauv thoob ntiaj teb, tshwj xeeb tshaj yog rau cov pob zeb nyuaj thiab abrasive.Yog li feem ntau, lub ntsej muag tiaj tus nrog hemi-spherical nyees khawm tsim yog qhov kev xaiv nrov tshaj plaws.
Lub ntsej muag convex: Ib qho qauv tsim rau cov pob zeb mos mus rau nruab nrab nyuaj uas tsis yog abrasive.Qhov kev tsim no muaj qhov nkag tau zoo heev tab sis tsis zoo hauv qhov sib txawv yog tias pob zeb nyuaj.
Lub ntsej muag concave: Nruab nrab nyuaj rau cov pob zeb nyuaj uas tsis tshua muaj abrasive thiab tawg.Tshwj xeeb tshaj yog rau qhov sib sib zog nqus qhov drilling, zoo heev tswj lub qhov sib txawv.
