採石鉆機 的英文怎麼說
中文拼音 [cǎidànzhēnjī]
採石鉆機
英文
drill for quarrying-
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。Under the function of big pressure and dynamic load, the grains may be moved which may cause the soil body distortion. at present, the relatively ripe methods of drill in gravel layer are mostly double - wall drill pipe reverse circulation drilling, auger stem breast wall drilling and down - the - hole hammer follow down drilling
論文根據jsl ? 30型礫石鉆機潛孔錘同心跟管鉆具結構，採用程序計算得到了鉆桿內各深度處壓力分佈、鉆頭壓力降、環形空間壓力分佈及空氣流速分佈。Better methods of extraction mean we can drill nearly 10, 000 metres down and 8 km sideways ; and increasingly sensitive detection techniques have resulted in more oil being found than we could have predicted in the dark days of the seventies oil crisis
更好的採油方法就是我們能向下鉆深幾近1萬米，再側向鉆進8千米；而且日益靈活的探測技術已導致發現更多的石油，比在70年代石油危機的黑暗日子里我們預言過的石油儲量還要多得多。This product is under pressure, small bending radius, the anti - fatigue properties of strong, long life and other characteristics, widely used in metallurgical casting side, oil drilling, engineering machinery, and various types of hydraulic mining extraction machinery
本產品具有承受壓力高、彎曲半徑小、抗疲勞性能強、使用壽命長等特點，廣泛應用於冶金邊鑄、石油鉆探、工程機械、礦山採掘及各類液壓機械等。A new method of gaining the characters of rock and soil from the blasting drilling is studied, which is different from general methods and more economic and accurate than them. and a new rock classification is discussed, which involves fuzzy integrated judge method and the affecting factors of drilling
為更好地進行後期的爆破設計如炸藥與巖石的優化匹配等，本文綜合考慮各種影響鉆機鉆孔速度的因素，首次提出了採用模糊綜合評判的方法對鉆孔中獲取其性質的巖石進行分級。The initiative entitled " jewellery integrity campaign " aims to build up a self - regulating mechanism among the industry players through the adoption of clear trade descriptions in jade and diamond retailing activities
新計劃名為珠寶玉石誠信計劃，旨在推行自我規管機制，鼓勵珠寶玉石經營者在出售玉石及鉆石時採用清楚的商品說明。And it is worthy to say that this method is very simple to realize and suits for practical blasting engineering. 2. a new rock, classification based the rock drillability is discussed, which involves fuzzy integrated judge method and the affecting factors of drilling
（ 2 ）以巖石本身的可鉆性為依據，兼顧考慮到其他影響鉆機鉆孔速度的各種因素，採用模糊綜合評判的方法對通過鉆孔實時獲得其性質的巖石進行分級。分享友人
