Installation location: Atmospheric pressure tank Tip: If the tank is not normal pressure side, this fault can not be ruled out, smart replacement transmitter. 3. Another problem is that temperature changes may cause density changes and affect measurement. Hazard: can not be properly adjusted, prone to string gas and overpressure explosion.
1. First verify the double flange to determine its accuracy. (Film is not in good condition) How to determine the error of the double flange level gauge: Analysis of the cause of the failure: Underfilling of the lower pressure flange of the negative pressure means that the fluid is clogged, resulting in frequent occurrence of gas-liquid two-phase or solution space on the negative pressure side.
2. The insulation during positive and negative pressure operation is not good, there is no crystallization, resulting in blocking, causing the measurement to be incorrect. -[!d#.v6h Analysis points: The liquid level meter cannot be blocked, and the analysis of the level gauge itself and the nature of the medium is important, taking into account the environmental impact.
Double flange level gauge fluctuates greatly:
The double-flange level gauge of the pressure checkout table is normally displayed after the initial setting, and a large error occurs when the liquid level changes, and the time period of the static liquid surface shows fluctuations.
Failure Analysis:
1, the pressure tube (capillary) may leak.
2, the media is too thick.
3, the tank exhaust is not smooth.
Handling: Unblock and find out the reason to prevent it from reappearing.
Symptom: The liquid level display frequently fluctuates between zero and a relatively fixed value.
Hazards: May cause spillage or empty cans that cause waste or affect production.
Check the processing results: Through the analysis of the basic elimination of equipment and media effects, through the fluctuation of the liquid level scoring period to determine its sensitivity to temperature, and therefore think that the tank may be the guide pressure medium is not normal, the capillary gap. Moving the negative pressure flange to the bottom for a period of time has improved, and it is determined that the negative pressure capillary has an air gap. Remove the capillary after troubleshooting.
Installation location: CO2 absorption tower.
