稳杆器是钻具的一个主要部件,也是一个易损部件,它的好坏直接影响钻头寿命。几年来我们使用过叶片式、整体式和滚筒式三种稳杆器。其中数叶片式的结构简单,性能较好,叶片磨损后便于更换。但叶片不耐磨,寿命比较短,曾在45R牙轮钻机上实测6支,穿岩平均寿命1612米/支,在60R牙轮钻机上实测6支,穿岩平均寿命654米/支,两种牙轮钻机12支稳杆器,穿岩平均寿命1133米/支。 Stent rod is a major component of the drill, but also a vulnerable component, its quality directly affects the life of the drill. Over the past few years we have used a vane, monolithic and roller three stable rod. The number of leaf-type structure is simple, better performance, easy to replace the blade wear. However, the blade is not wear-resistant, short life expectancy, has been measured in the 45R cone drill 6, the average life expectancy of rock 1612 m / support, 60R cone drill on the measured 6, wearing rock average life expectancy of 654 m / support, two Twelve cone gear rod drilling rig, wearing rock average life of 1133 m / support.
