4 1/2 ″ Api 4 Mapiko Chevron Kokani Bit Yobowola Geothermy

Dzinthu za rag bits:

1, A olimba chidutswa chimodzi kutentha ankachitira, 4140 aloyi zitsulo thupi kwa pang'ono mphamvu & durability;

2, CNC ya threaded Machining kwa unsembe bwino & ntchito;

3, Ma forgings amapangidwa kuti akhazikitse bwino ma carbide.

4, Sankhani tungsten carbide amaika 5.5mm wandiweyani ndi muyezo.

5, Relief ndi kumbuyo kwa zoyika za carbide kuti zigwire bwino ntchito.

3 mapiko ma step drag bits ndi chidutswa chimodzi chopangidwa ndi chitsulo chopangidwa ndi tungsten carbide nsonga ndi mbali zoyezera kuti moyo ukhale wautali.

Ili ndi mapiko atatu ndi mabowo atatu ogwetsera.Poyerekeza ndi mapiko anayi, mapiko atatu okoka masitepe amakonda kubowola mwachangu komanso mwamakani, pomwe, amakhala aafupi komanso osakhalitsa.

3 mapiko masitepe kukoka pang'ono kutulutsa mphamvu yodula kwambiri kuposa kalembedwe ka chevron.Kuthamanga kwa tebulo lozungulira kwa masitepe kuyenera kukhala pakati pa 60 ndi 80 rpm ndi kulemera kochepa pa bit (WOB).

3 mapiko masitepe kukoka mapiko ndi zida zachuma pobowola zofewa za geological mapangidwe ndi kuya kosaya, iwo makamaka amapangidwira mapangidwe ofewa apakatikati, monga Clay, Loam, Silt,

Dothi lambiri lasoft-to-medium lomwe lili ndi chinyezi, ndi zina zambiri. Komanso masitepe amakoka amalimbikitsidwa pobowola mu Mining,

Kufufuza, Zachilengedwe, Chitsime cha Madzi, Kusinthana kwa Geo, etc.
