GX CS4 my problem

[miksatx]

Just received to compressor today serviced the water reservoir topped off . I turned the water on closed the bleed valve it was pumping up the pressure then about a 100b something inside the case popped and the pressure just dropped to zero. Now not building pressure.
can’t believe it lol! Help

Did you check the burst disc yet? Also sometimes the banjo fittings may not be completely tight on the HP tubing. First thing I would do is check the burst disc.

Burst disc was fine the pop sound came from inside the case. So guess I’ll check the banjo fittings next. Thanks MACTEN

That's where my money is, especially if it "popped".

Not sure what happened No banjo bolt were lose. I tipped the unit to each side. I put the deadhead in the hose turned on the water set the shutoff at 100b shut the bleeder valve it pumped to 100b and shut off like nothing ever happened. Well guess I’ll put the case back on and check it out again.

I'm guessing it was a power supply issue. Since it's inside you cannot tell. I have the external power supply CS4 and the second time I tested it the power supply over current or some protection circuit went pop and it stopped working. Hey let it cool down for 5 minutes try to get never had the problem again. However I don't really trust the quality of the power supply but that's not a big deal since replacements aren't that expensive.

So just tried filling my AEA ultralight to 250 bar. Took almost 5 mins does that sound right? It seems like it would take forever to 350b in my GK1. Sprayed soapy water on fill fittings didn’t see any leaks.

The pump is rated for 11 L per minute but I would use the number 10 L per minute. So to find the approximate time to fill a vessel multiply the liters of the vessel times the number of bars that you want to increase the pressure by and that's how many liters of air that you have to pump into it. Then divide that by 10 L per minute to get the time.

Do you have a filter on the output hose?

I did have, I stopped the compressor pulled it off Bled the air off and restarted the compressor. Guess I will grab other ultralight and fill it to 250 and time it.

With no filter installed or being used put the deadhead in your fill line. Close the bleeder valve start your compressor if memory serves me right I think it was 37 or 39 seconds to go from zero to 300 bar.
It's in the manual.

Quickest and easiest way to check your compressor output...done.

I ask because the filter will add 2-3 minutes to the fill time, what with the internal volume and the extra hose.

What's your DH time to 310 bar?

Thanks Mike I’m on it as soon as my phone gets some charge on it.

Don’t know yet waiting on my phone to charge up some.

 

[miksatx]

Ok seems when I checked the burst disc I didn’t get it tight enough and was leaking enough I could hear it. Snugged it down .
deadhead time for 300b 23 sec. to 310b 24sec. Now I think it good. Fingers crossed! Lol

I'm curious... why did you have to charge your phone to do a DH test??

I use the stop watch setting to time the deadhead time.

Your compressor must be special or something. Manual states 38 seconds from 0 to 300 bar, yours does it in 23 seconds.

Yep. Didn’t think it was any thing special about it.

Mine does it in 23.6 seconds. 0-400 in 27.92 seconds.
