How to determine if a vacuum pipeline is blocked?
Thread Content
In the vacuum pipeline of the reactor, a small amount of liquid and powder is drawn out from the material; over time this can lead to blockages in the pipeline. Is there a reliable way to determine whether there is a blockage in the pipeline?
Is it okay to install vacuum pressure gauges in different locations?
Compare the readings of the vacuum gauges.
I was wondering: as long as it’s not completely sealed, the reading on the vacuum gauge won’t change significantly over an extended period of time, right?
Observation only in a dynamic context is effective. Gas with a certain flow rate is passed through the pipeline to measure the pressure difference. In one of my pipelines, I use nitrogen at a flow rate of 4 m3/h; if the pressure difference exceeds 0.1 Mpa, it means that the setup does not meet my production requirements
Could you describe it in detail? Thank you!
If the evacuation speed required for your production is 300 L/s, then gas with a flow rate greater than 300 L/s should be used, assuming that the measured pressure difference is 1 kPa. If the pressure difference allowed by your production system is greater than 1 kPa, it indicates that production can still be carried out; otherwise, it means there is severe blockage and production cannot be sustained
