I-DTH hammers rock bits izingcezu ezincane zokumba amatshe ziyathengiswa
Incazelo Yomkhiqizo
Ikhiqiza ububanzi obubanzi bezinkinobho ezihambisana nazo zonke izinhlobo nosayizi bazo zonke izinhlobo ezidumile zezando ze-down-the-hole.
Kutholakala ezinhlobonhlobo zezitayela zekhanda kanye nezinkinobho, zenzelwe ukunikeza abashayeli ithuba lokukhetha i-bit engcono kakhulu yokubhoboza kahle zonke izinhlobo zamatshe ahlukene nezimo zomhlabathi.
Zonke izingcezu ezisebangeni eliphakathi zenziwe ngensimbi ephezulu ye-nickel alloy, ephathwa ngokushisa ukuze ikhiqize indawo ekwazi ukumelana nokukhathala nokuguga.
I-DTH (Down to Hole) i-drill bit, ebizwa nangokuthi i-spline drill bit, isetshenziswa kakhulu emayini yesikali (evulekile nangaphansi), inkwali evulekile kanye nokwakhiwa.Isando sibekwe phansi kwembobo ngokuxhumene ngqo ne-drill bit nama-splines kubhithi.I-hammer piston ishaya i-drill bit okuholela ekudluliseni okusebenzayo kwamandla omthelela kanye nokulahlekelwa kwamandla okungabalulekile ngokujula kwembobo.

Ungasikhetha Kanjani I-DTH Bits Face shape kanye ne-Carbide Button Shape
A:Ukukhetha ukuma kobuso bebhithi
I-Drop Center Bit
Ukuze uthole amazinga aphezulu okungena ekwakhiweni kwamadwala athambile kuya kokuphakathi-aqinile futhi aqhekekile.
Ubuso be-Concave
Ibhithi yohlelo lokusebenza eyindilinga yonke ibhekene ngqo nokwakheka kwetshe eliqinile nelilinganayo.Ukulawula okuhle kokuchezuka kwembobo kanye nomthamo omuhle wokushibilika.
Ubuso obuconvex
Ngamazinga okungena aphezulu kokuthambile kuya kokumaphakathi-nokuqina nomfutho womoya ophansi kuya omaphakathi.Iwukumelana kakhulu nokugeza kwensimbi, nokumelana okuhle ne-steel wash gauge bit.
I-Flat Face Bit
Lolu hlobo lomumo wobuso lufanele ukwakheka kwamatshe aqinile kuya kokuqina kakhulu futhi abrasive izicelo ezinomfutho womoya ophezulu.Amazinga okungena amahle ukumelana nokuwashwa kwensimbi.
B:Faka Ukukhethwa Komumo Wenkinobho Ye-Carbide
Inkinobho ehlukile ilungele izimo zaphansi ezihlukene, amazinga abrasive, ama-PSI namazinga okungena.Ngokuvamile, ukwanda kwezinkinobho zegeji, kuba ngcono ngaphezu kokusebenza, ikakhulukazi ku-hard rock.
I-Spherical
- Amandla ohlelo lokusebenza-izinhloso eziningi
- Ifaneleka kakhulu ku-abrasive ethambile
- 25,000 kuya ku-45,000 PSI (170 kuya ku-300 MPa)
- I-Abrasive kuya ku-abrasive kakhulu
Inkinobho yeBallistic
- Amandla ohlelo lokusebenza- ukungena ngokushesha
- Ifaneleka kakhulu endaweni ethambile
- 10,000 kuya ku-20,000 PSI(70 kuya ku-140 MPa)
- Umhlabathi ongewona ama-abrasive
I-semi-ballistic
- Ukungena kwamandla ohlelo lokusebenza
- Ifaneleka kakhulu endaweni emaphakathi
- 15,000 kuya ku-25,000 PSI(ama-MPs ayi-100 kuye kwayi-170)
- Umhlabathi olimaza kancane
Inkinobho Ehlanganisiwe (I-Conical).
- Amandla ohlelo lokusebenza- ukungena ngokushesha
- Ifanele zonke izinhlobo zomhlabathi ezingahubi
- Indawo yokuxhumana encane
- Ifaneleka kakhulu kumabhithi e-diameter amancane
Izici ze-Nickel-alloy steel drill bits
1) Ukwethembeka
Ipiston ye-DTH Hammer isebenzisa insimbi ekhethekile (engenisiwe) ephezulu ye-nickel alloy, enokwelashwa okuthuthukisiwe okuthuthukisiwe njengezinga lemboni yezempi.
Ukuqinisa ukucubungula endaweni yesando ukuze kube nokumelana okuphezulu.
2)Ukufaneleka
Izingcezu zokubhoboza eziklanyelwe ngokukhethekile ukwakheka kwetshe elithambile neliqinile.Intambo yokuqaqa kalula ukuze ilungiswe kalula.
3) Ukusebenza kahle
Idizayini yesakhiwo esifushane kakhulu se-DTH isando kanye nebhithi yokusebenza kahle okukhulu kokudluliswa kwamandla okunomthelela omkhulu, namandla omthelela aphezulu kanye nezinga lokubhola elisheshayo.
Idizayini yesando nebhithi ithuthukiswa ngokulingiswa kwekhompyutha, ngegumbi lokusabalalisa umoya elingcono kakhulu kanye nedizayini yokuqina komoya.
