测深功能是旋挖钻机品质的一个重要参数。在旋挖钻机上设置钻孔深度显示装置,可以实时、准确显示钻孔深度,不需要人工多次放线测量。这不仅可节省人力和时间,还可提高钻孔效率、减少燃油消耗。钻孔深度可采用电感式传感器、增量式编码器和霍尔效应转速传感器测量,本文分别对这3种测量装置的工作原理进行介绍,并对其测量装置的精确度、可靠性、方便性等进行分析。1.电感式传感器测量装置电感式传感器测量装置主要由A、B电感式传感器(2个)、检测片、可编程控制器和显示器等组成。
Sounding function is an important parameter of rotary drilling rig quality. Set drilling depth display device on the rotary drilling rig, you can real-time, accurate display of drilling depth, do not need manual multiple pay-off measurement. This not only saves manpower and time, but also improves drilling efficiency and fuel consumption. Drilling depth can be measured using inductive sensors, incremental encoders and Hall effect speed sensors, this paper separately describes the working principle of the three measuring devices, and its measuring device accuracy, reliability, convenience Analysis. 1. Inductive sensor measuring device Inductive sensor measuring device is mainly composed of A, B inductive sensors (2), test pieces, programmable controllers and displays.
