浅谈压力表的检修技巧与不确定度评定

Discussion on Maintenance Technique and the Uncertainty Evaluation of Pressure Gauge

压力是生产过程中的重要工艺参数之一,也是指导生产的关键控制参数。特别是化工企业,压力参数尤为重要。压力表是一种最为常用的测压仪表,被广泛应用于石油、化工、冶金、电厂、能源、环保、机械制造等领域,对其进行准确检修具有十分重要的意义。现就个人平时的工作经验,谈谈压力表检修过程中的几点技巧和不确定度评定。

Pressure is one of the most important parameter in process of production, but also guide the key control parameters of production. Especially the chemical industry, pressure parameters is very important.The pressure gauge is one of the most commonly used pressure measuring instrument, are widely used in petroleum, chemical, metallurgical, power, energy, en vironmental protection, machinery manufacturing and other fields, has a very important significance for the accurate maintena nce. Now depending on the individual usually work experience, discussion some skills and evaluation of uncertainty during the maintenance about pressure gauge.
