Stage 3 labyrinth compressor starts up – purging the main motor
Thread Content
What does it mean to use nitrogen to purge the main motor during startup?
It involves ventilating the interior of various enhanced-safety, spark-free, or non-explosion-proof motors prior to startup, in order to ensure that the concentration of hazardous gases inside the motor is below the ignition level at the time of startup. ~~ Purging is accomplished using clean, dry, oil-free compressed air or an inert gas~~
It’s terrifying just to look at it; even starting the motor requires nitrogen treatment. Should it be nitrogen as the shielding gas? ? ? It would be best to send a video for everyone to see. I wonder what this type of motor looks like :)
The flowchart is drawn like this; I haven’t seen the actual motor yet
You should be aware of the environment in which it will be used; if it is a flammable or explosive environment, the term \"motor purge port\" seems a bit too casual. It should be called “nitrogen protection”. In normal usage environments, it should serve to cool down, right? Or dust purge? Special motors that cool down when the temperature rises? It is unknown. However, one thing to note is that if nitrogen purging is used, safety concerns regarding the environment should be taken into account. This should be taken into account, as an increase in the concentration of nitrogen in the environment can lead to asphyxiation incidents. (It’s just a guess; for reference only.) ）
