  1. The rotary gear reducer is driven by a dc motor through a gearbox to pro - vide bi - directional drill bit rotation

    轉動齒輪減速器是由一個直流電機驅動的，通過一個齒輪箱為鉆頭提供雙向轉動能力。
  2. Application of hall sensor in speed - regulation system of rotary three - cone bit drill

    霍爾傳感器在牙輪鉆機調速系統中的應用
  3. A new type rod damping stabilizer for rotary drills ispresented. it can increase the service life of rotary bit by about 27 % and its own life is over ten thousand meters. as a result, good econom ic benefit can be obtained

    介紹了牙輪鉆機用的一種新型減振穩桿器，提高牙輪鉆頭使用壽命27 %左右，其本身使用壽命超萬米，獲得了良好的經濟效益。
  4. According to achievements in research, using face - radial sealing structures can adapt to the developing trend of increasing rotary speed of cone bit to a certain extent in lubricating system of bearing seal, which is cramp to bit service life

    本文的研究表明，在偉l ]約鉆頭壽命的軸承密封潤滑系統中，採用端面一徑向組合密封結構能夠在一定程度上適應牙輪鉆頭轉速提高的發展趨
  5. The rotary carriage provides rotary and vertical motion to the drill string and bit

    轉動滑架為鉆柱和鉆頭提供轉動和垂直移動。
  6. The result of simulation of model 8 ? 1 / 2 ? xhp2s bit shows that, the torque on the bit changes randomly, and the degree of the change increases with the increase of the weight on bit ; the change of the torque on the upper part of the drillstring is not so large as that on the string ' s lower part, and the rotary speed of the bit changes smoothly overall

    對8英寸xhp2s鉆頭做了模擬，結果表明，鉆頭處受巖石的阻力扭矩是隨機變化的，並有負扭矩出現，扭矩的變化幅值隨靜鉆壓的增加而增加；鉆柱頂部轉盤施加的扭矩變化不如底部劇烈；鉆頭的轉速在局部有較小的波動，其總體變化較為平緩。
  7. By means of the simulation calculation, varying of the torques on the bit and the drillstring top and the rotary speed of the bit can be predicted

    通過模擬計算可預測鉆頭處阻力扭矩、鉆柱頂部扭矩和鉆頭轉速的變化情況。
  8. And complex rotary codes take charge of encoding and decoding the information bits again. though the rate is a bit lower and the complexity is a bit higher than the original rs codes, the error - correcting capability of rs - complex rotary codes is improved greatly compared with rs codes. because rs - complex rotary codes can be adjusted according to the practical request, it is a class of practical code

    該碼以rs碼為主體結構，同時對信息元進行復轉碼編譯碼，雖然碼率較之原來的rs碼有一定降低，復雜度也略有提高，但是糾錯性能卻由此獲得了較大幅度的提高，同時也使碼字糾錯能力可根據通道要求而進行調節，從而大大增強了實用性。
  9. Practice and analysis of rotary - percussive drilling of impregnated diamond bit with liquid jet hammer

    射流式液動錘回轉沖擊孕鑲金剛石鉆頭鉆進的實踐與分析
