密度三侧向探管的故障分析

Density Trilateral Probe Malfunction Analysis

根据密度三侧向探管的工作原理,对该探管在工作中常出现的电源不振荡,直流高压过低,三侧向电路的供电不足、电流不反馈、部分档位误差大,数字传输不正确,放射性输出重复突变、面板无显示或测井无输出等故障现象进行剖析,指出各类故障的易发位置、器件名称与标准指示值,提出了排除故障时应采取的检查方法及相关程序。

Based on operational principle of trilateral probe, analyzed the probe＇s frequent malfunctions of power source nonoscillatory, too low HVDC, trilateral circuit power supply shortage, non-feedback current, larger errors in part of grades, incorrect digital transmission, radioactivity output duplication mutation and no display on panel or no output well logging. Pointed out all manner of malfunctions easy to happen area, name of devices and standard targeted values, put forward checking procedure and related process to eliminate malfunctions.
