Mitundu Yosiyanasiyana Yobowola Bits

Kubowola pang'ono ndi chimodzi mwazinthu zofunika kwambiri pakubowola bwino. Chifukwa chake, kusankha mabatani oyenera kubowola ndikofunikira kwambiri. Zobowola pobowola mafuta ndi gasi zimaphatikizapo tizidutswa tating'onoting'ono tating'onoting'ono ndi zodulira zokhazikika.

Ma Rolling Cutter Bits

Zodula zodula zimatchedwanso ma roller cone bits kapena tri-cone bits. Masamba odulira amakhala ndi ma cones atatu. Koni iliyonse imatha kuzunguliridwa payekhapayekha pomwe chingwe chobowola chimazungulira thupi la pang'ono. Ma cones ali ndi mayendedwe odzigudubuza omwe amaikidwa panthawi yosonkhanitsa. Zidutswa zodulira zitha kugwiritsidwa ntchito kubowola mawonekedwe aliwonse ngati chodulira choyenera, chonyamula, ndi mphuno zasankhidwa.

Pali mitundu iwiri ya tizidutswa tating'onoting'ono tomwe ndi timilled-tooth bits ndi tungsten carbide inserts (TCI bits). Tinthu tating'onoting'ono timagawika m'magulu a mano:

Milled-mano bits

Milled-tooth bits ali ndi zitsulo zodula mano, zomwe zimapangidwa ngati zigawo za bit cone. Tizidutswa tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono kapena tozungulira. Mano amasiyana kukula ndi mawonekedwe, malinga ndi mapangidwe ake. Mano a bits amasiyana malinga ndi mapangidwe motere:

Mapangidwe ofewa: Mano ayenera kukhala aatali, owonda komanso otalikirana. Mano amenewa amatulutsa tizidutswa tatsopano tating'onoting'ono tomwe timapanga tofewa.

Tungsten Carbide Insert (TCI) kapena Insert bits nthawi zambiri amakhala ndi tungsten carbide insert (mano) omwe amawapondereza mu tinthu tating'onoting'ono. Zoyikapo zimakhala ndi mawonekedwe angapo monga mawonekedwe otalikirapo, zoyikapo zozungulira, ndi zina.

Mano a bits amasiyana malinga ndi mapangidwe motere:

Mapangidwe ofewa: Zowonjezera zazitali, zoyikapo ngati chisel

Mapangidwe olimba: Zowonjezera zazifupi, zolowetsa zozungulira

Zodula Zokhazikika

Zodula zokhazikika zimakhala ndi matupi ang'onoang'ono ndi zida zodulira zophatikizidwa ndi matupi ang'onoang'ono. Zodulira zosasunthika zimapangidwa kuti zizikumba mabowo pometa mikwingwirima m'malo momadula kapena kugubuduza, monga zodulira. Zidutswazi zilibe magawo osuntha monga ma cones kapena ma bearing. Zigawo za bits zimapangidwa ndi matupi ang'onoang'ono opangidwa kuchokera kuzitsulo kapena tungsten carbide matrix ndi masamba osasunthika ophatikizidwa ndi odulira osamva abrasion. Odula muzitsulo zomwe zimapezeka pamsika ndi Polycrystalline Diamond Cutters (PDC) ndi ocheka a diamondi achilengedwe kapena opangira.

Masiku ano, ndi kusintha komwe kwapangidwa muukadaulo wokhazikika wa cutter bit, ma PDC bits amatha kubowola pafupifupi mtundu uliwonse wa mapangidwe kuchokera ku zofewa mpaka zolimba.

Mabowo a polycrystalline diamond compact (PDC) amapangidwa ndi odula a diamondi opangidwa ndi chitsulo kapena matrix. Zobowola za PDC zidasintha ntchito yobowola ndikugwiritsa ntchito mosiyanasiyana komanso kuthekera kwakukulu kolowera (ROP).

Ngati mukufuna PDC cutter ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIL pansi pa tsambali.
