Pansi pa dzenje dth hammer QL SD mndandanda wamtengo ku China

Kufotokozera Kwachidule:

1. Perekani mphamvu zochulukirapo pobowola pang'ono, kuthamanga kwachangu komanso kutsika kwa mpweya chifukwa cha mawonekedwe apadera amkati a HD mndandanda wa DTH nyundo yopangidwa molingana ndi chiphunzitso chaposachedwa kwambiri chobowola miyala.
2. Kuchita bwino komanso moyo wautali wautumiki wa nyundo ya DTH chifukwa cha zida zapamwamba za alloy zitsulo ndi ukadaulo wapamwamba wosinthidwa.
3. Mlingo wochepa wa vuto komanso wosavuta kukonza chifukwa chosavuta, chodalirika komanso chosavuta kusonkhanitsa ndi kusokoneza dongosolo lamkati la nyundo.
4. Chosavuta kuchoka ku nyundo chifukwa cha ulusi wamutu wambiri wolumikiza chuck ndi silinda ya nyundo.
5. Kusinthana ndi DTH bit ndi kubowola chitoliro

Nyundo za TDS Down the Hole zimasiyana kuchokera ku 2.5 mpaka 12 mainchesi awiri ndipo DTH bit imachokera ku 3 "mpaka 18" awiri.Chitsulo chamtengo wapatali chophatikizika ndi carbide yabwino m'manja mwa mainjiniya athu odziwa zambiri zimatsimikizira zobowola zapamwamba kwambiri.Nyundo zathu zimatulutsa kulowa kwambiri pakugwiritsa ntchito mafuta ochepa.Ngakhale otsika mpweya kuthamanga, amapereka pazipita ntchito.Nyundo zathu za DTH zimagwiritsidwa ntchito pobowola zitsime za Madzi, migodi ndi miyala komanso pomanga.Ma bits a DTH amapezeka ndi masitayelo osiyanasiyana amaso monga concave, convex ndi flat.
