浅析一般压力表误差超差的原因及解决办法

On the general stress tolerance error indicating the cause and solutions

一般压力表由于它结构简单、坚固耐用、维护方便、读数明显,在监控铁路设备安全运行方面起到了至关重要的作用。因此要求对压力表执行强检,检定周期为6个月。但压力表经过一段时间的使用,由于各种原因出现示值超差,而示值超差影响压力表数值的准确性,不能起到监控设备的作用,给铁路安全运行带来危险,甚至造成重大事故。因此分析造成一般压力表示值误差超差的原因,并找出相应的解决方法,尽可能减小示值误差是计量员的一项职责,也是一名计量检定员技术水平的体现。本文正是对这一问题进行了分析并提出几种解决办法。
