Lus piav qhia luv luv:

TDS yog lub ntiaj teb cov chaw tsim khoom ntawm percussion drilling khoom.Nrog ntau tshaj 20 xyoo dhau los, peb txoj kev cog lus rau kev ua tau zoo ua kom cov khoom lag luam txhim khu kev qha uas yuav ua tau txhua lub sijhawm.Peb siv cov thev naus laus zis tshiab hauv engineering los tsim cov qauv tsim.Peb siv txoj hauv kev uas ua tau raws li cov qauv hauv aerospace hauv kev tsim cov hammers zoo thiab me ntsis

Qhov zoo tshaj plaws ntawm qhov loj me rau blast qhov drilling nrog DTH yog 90 hli txog 254 hli (3 ½ "-10").Cov qhov me me yog feem ntau drilled siv tophammer, thiab qhov loj dua feem ntau siv cov cav tov teb.

Hauv lwm daim ntawv thov, zoo li lub hauv paus drilling, DTH hammers tuaj yeem siv nrog ib qho me me hauv qhov ntau thiab tsawg mus txog .750 hli (30 ").Nrog ntau yam rauj units CD (Cluster drills) laum qhov txog li 70 "los yog 1778 hli.

Raws li txoj cai ntawm tus ntiv tes xoo, qhov tsawg tshaj plaws txoj kab uas hla ntawm DTH rauj tuaj yeem xyaum yog nws qhov loj me.Ib tug 4 nti rauj yuav laum 4 nti (102 hli) qhov.Qhov kev txwv qhov tseem ceeb yog sab nraud txoj kab uas hla ntawm rauj, vim hais tias, raws li qhov txoj kab uas hla txo, airflow yog txwv.Qhov siab tshaj plaws qhov loj rau kev tsim khoom drilling yog qhov nominal rauj loj ntxiv rau 1 nti, yog li rau 4 nti rauj qhov siab tshaj plaws qhov loj yog 5 nti (127-130 mm).

Xaiv txoj cai rauj feem ntau txiav txim siab los ntawm qhov loj thiab hom pob zeb tsim.Qhov zoo tshaj plaws, qhov luaj li cas ntawm lub rauj yuav tsum phim qhov yuav tsum tau lub qhov ntev kom zoo li qhov ua tau, tawm hauv qhov chaw txaus rau cov txiav kom tshem tawm lub qhov.
