2nd Stage Bauer 320D not build up pressure

[danisafety]

Hi Guys,
I am working on Bauer compressor 320D. I have problem when I run the compressor but the 2nd stage not build up pressure perfectly. It goes up but just go back down again. anyone can help me?

Hi, a little more information could be helpfully. Have you cheked the condensat drain valve, is it leaking ? What about the safety-valves ? Tried a "blow-by" test ?

Is this unit equipped with an auto condensate drain?

I checked on condensat drain vale but no leaking there. but for safety valve what type test that I can do? Then also can you explain me about how to perform "blow-by" test?
Thanks

No, we should do manually by condensate drain valve..

The auto drain is controlled by a "repeat cycle" timer. This timer has two setting. One controls the interval between cycles (minutes) and the other controls the duration of the cycle (seconds). The factory usually sets the interval at 15 minutes and the duration at 8 seconds. If the unit builds pressure and immediately loses it, it is possible that the drain interval setting has moved to minimal, a minute or less. What I suspect though, since you didn't mention that the pressure builds, drops and builds again in a continuous repeatition, is that the unit is running long enough to enter a drain cycle, but never builds pressure again. This could happen from 10 to 20 minutes depending on the interval setting. If this is the case, your drain timer is bad. I have seen this happen many times with solid state timers.
