Due to the characteristics of pipeline, process and full closure of production operations, especially the modern enterprise has a high level of automation. The process operation is closely related to the instrumentation. The process personnel pass various types of process parameters such as reaction temperature and material flow. The pressure and liquid level of the container, the composition of the raw materials, etc. to judge whether the process production is normal, whether the quality of the product is qualified, according to the instructions of the meter to increase or decrease the production, or even stop.
The instrument indicates an abnormal phenomenon (indicating high, low, no change, unstable, etc.), which itself contains two factors: one is the process factor, the meter correctly reflects the abnormal process; the second is the instrument factor, due to the meter (measurement System) A failure of a certain link causes the process parameter indication to be inconsistent with the actual. These two factors are always confused, and it is difficult to immediately determine where the failure is. Instrument maintenance personnel should improve the ability to judge the fault of the instrument. In addition to familiarity with the working principle, structure and performance characteristics of the instrument, it is also necessary to be familiar with every link in the measurement system. At the same time, the characteristics of the process flow and the process medium and the characteristics of the equipment should be Understand that this can help with instrument maintenance.
In short, when analyzing the cause of the field instrument failure, pay special attention to the changes in the characteristics of the controlled object and the control valve, which may be the cause of the failure of the field instrument system. Therefore, we must comprehensively consider and carefully analyze the two aspects of the field instrument system and the process operating system to check the reasons.
