一、使用中存在的问题我厂催裂化装置催化剂贮罐的料位检测,采用 UTZ—01型浮标式防爆料位计。该表在我厂使用的效果不良,一直未能正式投运。主要存在下列问题。1.浮标不能自动返回。该表检测料位时,探测料面的浮标接触到料面时,必须人工扳动返回(回零)开关,浮标才能往上提 First, the use of the existing problems I plant catalytic cracking catalyst storage tank level detection, the use of UTZ-01 buoy-type explosion-proof level gauge. The table in our factory using the poor results, has not been officially put into operation. The main problems are as follows. 1. The buoy can not be returned automatically. When the table detects the material level, when the buoy of the material surface is touched to the material surface, it must be manually turned back (back to zero), the buoy can be raised
