鉆頭轉速 的英文怎麼說
中文拼音 [zhēntóuzhuǎnsù]
鉆頭轉速
英文
bit rotation speed-
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。The recent development trend of cone bits is to realize their high speed. faster the speed of bit is, the more weak of common bearing seals worked under the rough environment is
牙輪鉆頭目前的發展趨勢是實現高速化，隨著鉆頭轉速的不斷提高，在惡劣環境下工作的普通軸承密封這一環節的薄弱性將顯得越來越突出。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3 transmission, built in the top drive power head, has two speed range ? high and low. it can meet the requirements of both dth hammer drilling and carbide bit drilling
3動力頭設有變速裝置，有高低兩個檔次，以滿足潛孔錘鉆進及硬質合金回轉鉆進方法。Studies have shown, lead impeller nozzle it forms the hole to be equal to size of the nozzle, gush out from light, difficult to arrange bits and realize it cut one layer of advantages effectively ; under the equal condition, rotate the nozzle by oneself, can be designed in accordance with the actual need while vary the size of aperture of hole, gush out the distance longer effectively, it is apt to give play to the role of its pulse broken rock
以此設計出限速部分的參數，且初步討論射流功率與轉速之間的關系。研究表明，內導葉輪噴頭形成鉆孔孔徑與噴頭大小相當，有效噴距小，不易排屑和實現其切向剝層優勢；同等條件下，自旋轉噴頭，成孔孔徑大小可依實際需要設計，有效噴距較長，易於發揮其脈沖破巖作用。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。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。Bit rotation speed
