在水文地质勘探工作中,为了取得正确的资料和进行抽水试验,开孔口径愈大愈好。但 KA-2M-3000型钻机,开口直径仅为130—115公厘,同时是用迥转钻进的。所以就很难满足水文地质勘控的要求.为此我们就将 KA-2M-300型钻机改装为冲击旋转两用钻机,以适应在砂卵石层中顺利钻进。大家都知道 KA-2M-300型钻机的传动系统是:由柴油机发出的动力,经过中间轴的变速而传递到钻机工作
In hydrogeological exploration work, in order to obtain the correct information and carry out pumping tests, the larger the hole diameter as possible. However, KA-2M-3000 drilling rig, the opening diameter of only 130-115 mm, while drilling is used to turn around. So it is difficult to meet the requirements of hydrogeological survey and control.To this end we will KA-2M-300 drilling rig converted into impact rotary dual-purpose rig, to adapt to the smooth gravel layer in the drilling. We all know that KA-2M-300 drilling rig drive system is: the power emitted by the diesel engine, after the transmission through the transmission shaft to the rig work
