Chiyambi cha Tricone Bits
Tricone bit ndi chida chofunikira pobowola mafuta.Kugwira kwake ntchito kumakhudza mwachindunji kukumba bwino, kubowola bwino komanso mtengo wobowola.Zodzigudubuza: Zitha kugawidwa mu cone imodzi, cone iwiri, tri cone ndi ma cone angapo malinga ndi kuchuluka kwa wodula.Tricone bit ndizomwe zimagwiritsidwa ntchito kwambiri kunyumba ndi kunja.Zogulitsa zathu zimagwiritsidwa ntchito makamaka mu: kubowola mafuta, chitsime chamadzi, kubowola gasi wachilengedwe, kukumba bwino kwa geothermal, kubowola bwino kwa mpweya, kufufuza migodi ya malasha, migodi, kumanga mlatho, ndi zina zotero. Tili ndi zinthu zosiyanasiyana kuphatikiza ma DTH bits, tricone bits, PDC drill bits, zitsulo za diamondi zolowetsedwa, zitsime zamadzi, mafuta, migodi, mapaipi obowola, zobowola ndi zida zoboola.Landirani makasitomala atsopano ndi akale kuti mukambirane mgwirizano.
