  1. Diamond drilling replaced percussion drilling.

    金鉆探取代了沖擊鉆探。
  2. 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。
  3. This laser poss characteristic : t he output power attains 500w ; laser energy instability less than 2 % ; laser radiation angle : about 3. 5mrad. design a sort of new - style laser cutting head, using this equipment can carry out trepanning and percussion drilling processing

    這臺激光器所達到的參數為:輸出功率達到500w ;激光能量不穩定度: < 2 % ;激光的發散角: 3 . 5mrad 。
  4. Abstract : the paper presented a kind of drilling hole method that adopted direct circulation and percussion drilling, casing and cliff - protection by mud. the method applied in the complex gravel layer which has the trend to emerge cave - in and drop from the drilling wall

    文摘:介紹一種在砂卵石地層層厚復雜、孔壁易掉塊、易坍塌的鉆孔的成孔方法? ?正循環回轉與沖擊鉆進、套管與泥漿護壁成孔。
  5. Discussed shallowly the karst area percussion drilling pile is digging in hole pile construction question processing artificially application

    淺談巖溶地區沖擊鉆孔樁在人工挖孔樁施工問題處理中的應用
  6. The stroke reverse circulation drilling machine of czf2000 - 1800 type is produced by our company newly to adapt to the demand of percussion drill market due to the development of road and bridge industry, it is specializedly used for pore forming of pebble and gravel stratum and hard stratum

    1800型沖擊反循環鉆機是我公司最新研製生產的為適應我國路橋事業發展對沖擊鉆機市場的需求，專門用於卵礫石地層、堅硬地層中成孔的鉆機。
  7. The results showed that the application of the two new types of water - saving percussion tools can not only saved a lot of water during the course of drilling, but also improved drilling efficiency greatly, and had developing prospect in drought and water - scarce area

    結果表明，這兩種新型節水沖擊器的應用不僅能夠大量節約鉆探過程中的用水量，而且能夠大幅度提高鉆探效率，在乾旱缺水地區具有廣泛推廣應用前景。
