Izinhlobo zezinkinobho ze-DTH nezinkinobho ezikuyo

Namuhla, ukukhiqizwa kwe-tungsten carbide kuvela ezimeni zokusebenza ezihlukene njengamathuluzi e-tungsten carbide noma impahla ye-tungsten carbide enamathiselwe kwamanye amathuluzi amakhulu. Ibhithi yenkinobho ye-Down-The-Hole (DTH) ihlale idinga izinkinobho zekhwalithi ephezulu ze-tungsten carbide ezimelana nomthelela ophezulu kanye nokuguga okulimazayo. Izinkinobho ze-DTH zisetshenziselwa ukubhoboza i-DTH ukuze kukhiqizwe imbobo eqondile noma imbobo yokuqondisa enobubanzi obukhulu. Angasetshenziswa futhi ukubhoboza amatshe aqinile futhi aqinile. Kulesi sihloko, sizokhuluma kabanzi mayelana nezinkinobho ze-DTH nezinkinobho ze-tungsten carbide ezisetshenziswe kuzo.

Izinhlobo zezinkinobho ze-DTH Bits

Ngokusho kobuso obuhlukene bezinkinobho zezinkinobho, izinkinobho ze-DTH zingahlukaniswa zibe izinhlobo ezintathu zezinkinobho zezinkinobho. Ziyizinkinobho zeconcave, izinkinobho zeconvex, nezinkinobho ezinobuso obuyisicaba.

1. Izinkinobho ze-Concave

Izinkinobho ze-concave zibonakala ngobuso obuyi-concave kanye nobuso obuyindilinga ebusweni bebhithi yenkinobho. Umugqa ongaphakathi kanye nomugqa wangaphandle konke kufakwe nezinkinobho ze-tungsten carbide. Futhi umugqa ongaphakathi ufakwa ukuvikela umugqa ongaphandle ekuguge kakhulu. Ngokuvamile, izinkinobho ze-concave cishe zizobhekana nokubunjwa okuqinile kakhulu.

2. Izinkinobho zeconvex

Ngokuphambene nezinkinobho ze-concave, izinkinobho ze-convex zine-convex futhi ziyindilinga ngaphandle ebusweni bebhithi yenkinobho. Afaneleka kakhulu amatshe aqinile athambile noma aphakathi nendawo, njenge-limestone, shale, noma amadwala asegugile kakade. Njengoba imaphakathi ngaphandle, izingcezu zenkinobho ye-convex zizoba nezinga lokungena elingcono.

3. Izinkinobho zezinkinobho ezinobuso obucaba

Izinkinobho zezinkinobho ezinobuso obuphansi azinakho okungaphandle noma okungaphakathi enkinobho ye-tungsten carbide kodwa ziyisicaba nje. Zisetshenziselwa ukumba izakhiwo eziqinile njenge-granite, i-basalt, noma i-limestone eqinile.

Izinkinobho ze-Tungsten Carbide

Izinkinobho ze-Tungsten carbide ezinkinobho ze-DTH zenziwe ngempushana ye-WC kanye ne-binder efana ne-cobalt. Ngemva kwezinqubo ezilandelanayo ezifana nokuxuba, ukugaya, ukucindezela, kanye ne-sintering, izinkinobho ze-tungsten carbide zifakwe ubulukhuni obuphezulu, ukumelana, nokuqina. Ngezinkinobho ze-tungsten carbide kuyo, izinkinobho zezinkinobho ze-DTH zinamandla kakhulu.

I-ZZBETTER I-Tungsten Carbide ihlale ibeka izinga eliphezulu endimeni yokuqala. Uma uthanda izinkinobho ze-tungsten carbide futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGAXHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwekhasi.
