Mhando dzakasiyana dzeMigodhi uye matsime ekuchera Bits

Migodhi nekuchera mabheti mabhiti anofinha maburi anoboora nekupinza zvinhu zvematombo akapfava uye akaomarara. Iwo anoshandiswa mumigodhi, kuchera matsime, kuchera, tunneling, kuvaka, kuongorora geological, uye kuputika kwekushandisa.

Migodhi uye mabheti ekuchera mabheti anowanzo ratidza chinongedzo chine shinda yekunamatira kune chibooreso uye muviri usina mhango umo madhiri emvura anotenderedzwa. Mvura yedhiri inodiwa kubvisa zvibooreso zvakachekwa, kutonhodza zvishoma, uye kudzikamisa madziro echibhorani. Mhando dzemabhiti ekuchera matsime anosanganisira anotevera:

Tri-cone kana roller bitsine makoni matatu ane mazino, imwe neimwe iine kona yejenari yakamisikidzwa yakananga kubhiti rekutanga axis. Iyo angle yemagazini inoshandurwa maererano nekuoma kwekuumbwa. Meno enhongo imwe neimwe anoroverana kuti abereke muvhu. Iyo bhiti inofambiswa nehuremu-pa-bit (WOB) ichidhonzwa nekutenderera kwechibhorani chemusoro.

Pasi-paburi (DTH) nyundo zvidimbuanoshandiswa neDown-the-hole sando pakuchera makomba kuburikidza nemhando dzakasiyana-siyana dzematombo. Mukubatana nesando dzeDTH, sando dzekuboorera dzakagadzirwa nedhiraivha yakatsemuka yekutenderedza bhiti muvhu. DTH mabhiti akatarwa-mumusoro mabheti ane conical kana chisel bit akaiswa anoenderana nematrix nezve dhiri bhiti musoro. Kugadziriswa kwemusoro kwebhiti kunogona kunge kuri convex, concave, kana flat.

PDC zvikamuine polycrystalline diamond compact (PDC) inoisa inogona kunzi PDC bits. Kusiyana nemabhiti etricone, PDC drill bits inhengo imwe chete isina nhengo dzinofamba uye yakagadzirwa kuti igare; chidimbu chega chega chakagadzirirwa mukati-mumba kuita, kuenderana uye kuvimbika. Sarudza Matrix kana simbi yakasimba-yakasimba kuti ienderane nekudhirowa kwakasiyana.

Mabhatani mabhitizvakafanana neDTH bhiti dzakagadzika-musoro mabhiti ane conical kana chisel bit akaiswa anoenderana nematrix nezve drill bit head. Kugadziriswa kwemusoro kwebhiti kunogona kunge kuri convex, concave, kana flat. Bhatani bhiti ndiro rinotenderera bhiti rakakodzera kune akawanda dombo rakaomarara, yepamusoro sando yekuchera maapplication.

Cross bits uye chisel bitszvimedu zvakagadzika musoro zvine simbi yakaoma kana mablades ecarbide. Mabhiti echisel anotsanangurwa neblade imwe chete nepo machinjiro aine mablades maviri kana anopfuura anoyambuka nepakati pebiti. Mablades anowanzo kuderedzwa akananga kunzvimbo yekucheka.
