FD-600全液压动力头反循环连续取样钻机研制与应用

Development and Application of FD-600 Full Hydraulic Power Head Reverse Circulation Continuous Sampling Drill

摘要:

文章结合国内外CSR取心技术的现状和所生产钻机的特点，为满足国内对空气反循环连续取样（心）、冲击回转、定向钻进等多种高效钻探工艺对钻机的需要，从钻机整体结构设计、整体布局进行详细考量，采用质量可靠的液压件、动力机等外购件，摒弃传统钻机设计周期长、动力小、机械化程度低、对地形和钻探工艺适应性低等特点，研制出了一台高效、可靠、机械化程度较高的FD-600型全液压动力头式反循环取样钻机。在3次野外生产试验中充分体现出了优越性，可满足砂金勘探、工程施工等取心钻探的要求。

Abstract:

Combining with the status quo of CSR coring technology both in China and abroad as well as the characteristics of drilling rig production, in order to meet the drilling rig requirements in China for matching air reverse circulation continuous sampling (coring), impact rotary drilling, directional drilling and other efficient processes, an efficient and reliable high-degree mechanization FD-600 type hydraulic power head reverse circulation sampling drill is developed, its overall structure and layout are designed in detail and the reliable purchased components such as hydraulic parts and engine are used, the drill reflects the superiority in 3 field production experiments and it shows that this drill can meet coring drilling for placer gold exploration and engineering construction.
