轉柱鉆機 的英文怎麼說
中文拼音 [zhuǎnzhùzhēnjī]
轉柱鉆機
英文
spindle drill press-
This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。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。On the basis of analyzing the rock mechanics, the bit working circumstance and property in the bottom hole of 6000m deep well, and making use of the former equipment such as a derrick, platforms etc, the paper demonstrates that the research and design of the mechanical device have been established including the high pressure simulating well bore, the high pressure connector between the static well bore and the rotating drill pipe, the high pressure simulating system of circulating fluid and the high pressure desander etc. the produce, control and dynamic analysis of the bottom hole four - dimensional pressure ( over burden, confined, pore and column pressure ) have been studied
本文在對井底巖石的受力狀態以及鉆頭的工作環境和特性加以分析的基礎上，藉助原有的井架、平臺等設備，研究設計了模擬6000米井底壓力壞境的高壓模擬井筒、鉆柱高壓轉聯器、鉆井液高壓模擬系統以及高壓除砂器等機械裝置，並研究了井底四維模擬壓力（上覆壓、圍壓、孔隙壓和液柱壓）的產生、控制及其控制的建模與模擬，從而實現井深至6000米的四維井底壓力環境的模擬。In chapter two, the rock mechanics and the bit working circumstance in the bottom hole of 6000m deep well have been discussed. on the basis of which the high pressure simulating well bore and the high pressure connector between the static well bore and rotating drill pipe have been designed
第二章分析探討了井底巖石的受力狀態以及鉆頭的工作環境，並依此研究分析了建立該模擬壓力環境的機械裝置?高壓模擬井筒和鉆柱高壓轉聯器。分享友人
