一、存在的问题自我公司常减压装置投用以来,由于仪表安装位置设计得不合理,仪表开孔位置距离塔盘太近,仅为50mm,致使减压塔中部溢流槽液位仪表无法正常使用,测量范围小。为了满足工艺要求,进行问题原因和解决方法分析与改造实践。在本次改造前,浮球及连杆与塔盘的相对位置如图1所示。由于受安装位置以及浮球自身结构的制约,当塔盘内的液位为零时,浮球的位
First, the existing problems Since the company atmospheric pressure relief device put into use, due to the installation of the instrument design is not reasonable, the location of the instrument opening too close to the tray, only 50mm, resulting in decompression tower central overflow tank level meter can not Normal use, small measuring range. In order to meet the technological requirements, carry on the analysis of the cause of the problem and the solution method and the reform practice. Before this transformation, the relative position of float ball and connecting rod and tray is shown in Fig.1. Due to the installation position and the structure of the float itself, when the liquid level in the tray is zero, the position of the float
