API 7-1 drilling Roller Reamer ine Type B & Type F & Type T roller

Tsananguro pfupi:

Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Kushandiswa Kwechigadzirwa

Roller Reamer yakagadzirirwa kushandiswa kwakasiyana-siyana kwekutsvaira asi kunyanya kugadzikana pakuchera nenzira dzinorema zvikuru. Inokodzera saizi dzemaburi dzinotangira pa4 5/8 kusvika 26inch. Pamusoro pezvo, muviri wega wega nekugadziriswa kuri nyore kwemabhuroko uye kusarudzwa kwakakodzera kwezvicheki, unokodzera saizi dzakasiyana-siyana dzemaburi.

Rudzi rwechigadzirwa

Mhando nhatu dzakasiyana dzekucheka (T,F naB) dzinowanikwa:

Rudzi T: Yakakuyiwa, yakagadzirwa nemazino akapinza akapinza kuti iite zvidimbu zvakapfava.
Rudzi F: Yakakuyiwa, yakagadzirwa nemazino akaomarara akatsetseka, kuti iite maumbirwo akaomarara ari pakati nepakati.
Rudzi B: Yakashongedzerwa nemabhatani etungsten carbide akadzvanywa mukati, kuti iite maumbirwo akaomarara.
