摘　　要：为降低亚临界汽包锅炉压力对汽包差压水位计指示的影响,分析了差压式水位计的工作原理,推导出因压力波动造成水位计指示值大幅变化的规律,提出相应工况下应该采取的调整方法,对防止锅炉出现"满水"或"缺水"事故、保持锅炉安全稳定运行具有重要意义。To reduce the influence of boiler pressure on indicating value of the differential pressure drum level gauge in sub-critical power units, an analysis has been performed on the working principles of differential pressure water level gauges, thus obtaining the rule of violent changes in indication due to pressure fluctuation. Corresponding adjustment methods are proposed, so as to prevent any full and lack of water accidents, which is of great significance in keeping safe and stable operation of the boiler.
