Hey buddy, I have a question
Thread Content
:The liquid level range of the balance vessel in Boiler D is 300_-300; it has been above 0 recently. For other liquid levels, even when they reach minus several dozen units, the gauge still cannot show a lower level – the lowest value it shows is just a few units above zero. Does any teacher know what the problem is?
It’s about adjusting the liquid level; this level can still fluctuate above 0. When the actual liquid level is below 0, this level doesn’t drop any further, staying at around 00 at the very least
In the event that the instrument readings are abnormal and one is unable to make a correct judgment, the issue should be reported to superiors as soon as possible without taking any actions on one’s own. This fruit might be a poisonous one. When interpreting gauge readings, it is necessary to consider the process principles. For all possible discharge scenarios, make every effort to carry out thorough testing, debugging, and experiments to identify potential issues. The rest can be left to the senior technical staff and leaders to handle. For reference.
Is the level gauge direct-reading or remote-transmission? If it’s a direct-reading type, has it been rinsed? Could it be that blockages or impurity bubbles are causing the problem? If it is for long-distance transmission, is the cable shielded? Could it be having an impact? If it is a remote transmission + direct reading type, and the two displayed values differ, it is recommended to replace it directly; there is no point in trying to repair it. There are too many hidden dangers.
Is it possible that the liquid phase valve is set too low and the container’s insulation is poor, resulting in a high liquid level?
