一、概述船用蒸汽锅炉汽鼓水位、蒸汽发生器水位,以及其它高温高压容器的水位,对于船用蒸汽动力装置的安全运行是非常重要的参数之一。以往,这些参数的测量大都采用差压计或就地云母水位计。但用于水位测量的差压计的安装位置往往置于被测容器底部,对于舰船动力装置来说,环境条件十分恶劣,安装及使用维护极不方便;同时,差压计结构复杂,脉冲管路较长,往往容易产生积气现象,使差压计工作不稳定。云母水位计的好处是直观,但不能远
I. Overview Steam drum boiler water level, steam generator water level, and other high temperature and pressure vessel water level, for the safe operation of marine steam power plant is one of the most important parameters. In the past, most of these parameters were measured using a differential pressure gauge or a local mica level gauge. However, the installation position of the differential pressure gauge used for water level measurement is often placed at the bottom of the container under test. As for the ship power plant, the environmental conditions are very poor, and the installation and use and maintenance are very inconvenient. Meanwhile, the structure of the differential pressure gauge is complex, Long pipeline, often prone to gas phenomenon, the differential pressure gauge work is not stable. The benefits of mica water level gauge are intuitive, but not far
