人造金刚石钻探用的钻机和一般岩心钻机的结构原理基本上是一样的,都是由三大系统所组成:即传给钻具回转力矩的回转系统,调节轴心压力的给进系统和升降钻具的升降系统.但是,由于人造金刚石钻头在钻进工艺上与钢粒或硬质合金钻进有很大的不同,所以,对钻机的性能也有不同的要求.1.人造金刚石钻进工艺对钻机的要求首先是高转速.实战证明,用人造金刚石钻头钻进时,转速愈高,效率愈高.这是因为目前使用的人造金刚石颗粒细小,在钻头上的出刃很有限,钻进时吃入岩石的深度就更小了,所以只有高转速才能充分发挥其破碎岩石的效能.在现有技术条件下,正常钻进转速可达1000~1500转/分左右.
Synthetic diamond drilling rig and general core drilling rig structural principle is basically the same, are composed of three systems: the rotary system to pass the torque of drilling tools to adjust the axial pressure feeding system and lifting drill However, since the synthetic diamond bit is very different from the drilling of steel particles or cemented carbide during the drilling process, it has different requirements on the performance of the drilling rig.1. Rig requirements first of all high speed. Actual proof, with synthetic diamond bit drilling, the higher the speed, the higher the efficiency.This is because the current use of synthetic diamond particles are small, the bit on the bit is very limited, when drilling to eat The depth of the rock is even smaller, so only the high speed can give full play to the effectiveness of its broken rock under the conditions of the existing technology, the normal drilling speed of up to 1000 ~ 1500 rev / min or so.
