进口牙轮钻机在钻具中多一个稳杆器,国产早期各类钻机中没有稳杆器,是钻具组中一个缺欠。稳杆器安装在钻杆的未端、钻头的上边,上头和钻杆连接,下头和钻头连接,是钻具中一个主要部件。据现场几次用稳杆器和不同稳杆器以及用不合格的稳杆器的试验表明,无论在提高钻头寿命和钻孔质量等方面,使用稳杆器都有很大提高。一、稳杆对钻头寿命的影响牙轮钻头在钻孔中,其上的每个牙轮均以钻头的垂直中心进行公转,而同时又绕自身的销轴进行自转。理想的钻进是钻头在孔中无横向摆动。但由于稳杆器的磨损,导向套的磨损,钻杆的
Imported cone drilling rig in the drilling more than a stable rod, all kinds of early drilling rig in China there is no stable rod, drill set is a deficiency. Steering rod installed in the end of the drill pipe, the top of the drill, the top and the drill pipe connection, the bottom and the drill connected to the drill is a major component. According to several tests conducted on the site with stable rods and different stable rods, as well as with unqualified stable rods, the use of stable rods has been greatly enhanced both in terms of improving bit life and drilling quality. First, the stability of the drill bit life impact roller cone bit in the drill, each cone on its vertical center of the bit to revolution, but at the same time around their own pin axis for rotation. The ideal drilling is the drill bit in the hole without lateral swing. But due to the wear of the stabilizer, the wear of the guide sleeve, the drill pipe
