It’s not that they aren’t explaining. It’s that you’re not understanding the explanations, which is at least somewhat understandable, particularly if you’re new to pneumatics. (I understood what they were trying to say, but I’ve been doing this for a while.)
Is our air compressor getting too hot at 181.8 F? answered the question with pictures. I’m going to try to walk through the answer without them, and I’ll reference the pictures as needed.
- Verify that you have 2x gauges in your system. One on the regulator or between it and the cylinder (downstream/low pressure gauge), and one somewhere between the compressor and the regulator (upstream/high pressure gauge). Fill your system. If they both read 60 PSI, the regulator is almost certainly the problem. [NOTE: If you don’t have two, you need to, because rules.]
- Verify that the regulator is pointing the correct way–see linked post. High pressure goes opposite the arrow.
- To set the regulator: Fill the system if you haven’t already. Pull UP on the black ribbed part–it’s a knob. Watch the downstream gauge. TURN the knob one way and see what the gauge does. Turn either the same way or the other way until the downstream gauge reads 60 PSI. Push DOWN on the knob to lock it.
Question: Is your tank upstream or downstream of the regulator? If it’s downstream, it’s not going to have a lot of air storage. Move it to the upstream side to double your storage capacity and halve your compressor usage. Or add a tank upstream to triple your storage capacity (approximately).
Question: Have you checked for teflon tape on your fittings on the cylinder and solenoid? (And that the fittings are tight?) If there isn’t teflon tape, or the fittings are loose, you found most of your problem.
Question the dumb: Describe the wiring of your pressure switch. There’s a slim but non-zero chance that there’s something off with that, particularly if your Pressure Relief Valve (the brass thing sticking UP from the compressor in the original post) is venting. I’d tell you how to check the PRV for proper calibration but that’s best done in person due to complexity–I think of us all, @GeeTwo is the closest.
I’m not trying to roll my eyes either, I’m trying to help you understand, and that may involve talking in what I’d call “highly simplified” language. Unfortunately, that’s what happens when you try to go from technicalese to less technicalese.
