Cesar Alejandro Kinzel HVAC thanks man!!!

Aaron Chevalley thanks man sorry for not having a video out recently work has been so slow it's scary but I might be doing some tool videos to substitute the lack of work available to record plus I'm going through some training right now and focusing on that! Thanks for watching man!!!

Paul Brayshaw thanks for your input!

Frankie M. They're good but parts are a bitch to get like Ingersoll-Rand has a hard time getting parts from Ingersoll-Rand not even kidding some stuff has happened and unless your in the industry you won't really know about it

joemar alegre sh-46 you can get it from summit oil online

Tony harrell If you’re just trying to figure out what year it was made you can check the motors play with the information on it sometimes they put the year manufacturing date on it but it’s also not 100% reliable if the motor has been replaced

Curious if you ever figured this out... its how I landed on this video!

@@shamusphone hi Shayne. Yes. I’ll send a detailed response tomorrow.

@@MrJudges4u Appreciate it!

@@shamusphone I replaced the main check valve part number 22380216 (corroded and clogged) located at the air intake and cleaned all other check valves. You can download the parts manual blow up schematics pics by calling Ingersol Rand tech line who has a historical library for all compressors dating back 20 years. Hope this helps.

@@MrJudges4u thanks! That's basically what I thought was best step. Just cleaned out the pilot valve and same exact scenario... nasty

TheSandler Your customer can possibly have what I call dirty voltage where at static voltage readings they have 230 but when the unit runs the voltage drops off causing higher amperage throughout the machine this is a big factor for any motor single phase or three phase failing prematurely as well as other electrical components or sometimes the customers power supplier doesn’t have regulated power and voltage changes throughout the day

What I would do if you have the tools to do it is do some data logging on the customers power if you know what that is

jae ho Seo you can contact IR directly and they can help you get the parts you need and ship them to you

FMBOSS is it a piston or screw? What seems to be the issue

It's a Quincy QSI 245 screw. It started out running up to 150 psi and activating the pop off valve. I discovered the air intake valve was stuck and corroded. I replaced all gaskets, seals and springs in same. I also cleaned out the pressure regulator (for air end), and unloader valve. Upon testing afterwards the unit would run up to pressure (125) unload way down to 50 psi and re load. It was dumping everything into the air intake via the blow down valve. I didn't think this was correct (it didn't work like this before). I thought the blow down was only when you turn the machine off. So I replaced the (125/110) pressure switch. Same thing happened. Checked the blow out valve, seemed to be tired although operating correctly. I replaced it anyway. New test run and still dumping lots of air into the intake when unloading. So it basically loads up to 125 lbs then unloads down to 75-80 lbs now. It cycles pretty fast like this. We inherited this machine back in 2014 and it never unloaded like this. It's "normal" mode back then was pump up to 125 and through plant usage lazily bleed down to 110 psi and reload. So, is it supposed to operate like this?? Dump all the air into the intake down to 80lbs and reload?

FMBOSS it depends on the manufacturer and model I’m not 100% sure with your unit but it does seem to be blowing out air from the inlet without oil coming shooting out of it as well it’s sounds normal of the machine. Now most machines that blow down from the inlet don’t do it as fast as you describe. If the unit is dropping the line pressure when it unloads it sounds like 2 things are going on. 1 I think you do not have the differentials set properly on the new pressure switch. 2 if your loosing line pressure as a result of the unit unloading pressure on itself and line you have a bad minimum pressure, this is basically a check valve on the machine. Without physically seeing the machine those are my best conclusions hope it was of help and good luck. If you need more help I would call the a local business who works on these or the manufacture usually manufacturers have free technical help over the phone.

The pressure switch factory setting was 125/110. I bench tested it and the differential. Acted as it should on bench. If I plugged the blow down valve, the unit cycled fine, differential and pressure wise. Line or plant pressure was not lost as fast. Check valve or minimum pressure vale tested ok. When I shut the machine down with the blow down valve plugged the plant service pressure did not back up into the unit. Benny, thanks for your help.

FMBOSS No problem I wish I could be of better help I’m not too well experience in Quincy pumps plus I’m no longer in the industry

Michael Lee thanks for your input stay tuned for a video coming out today!

Do you have phone number? I need my atlas copco fix... motor gets over load after five minute..

Claudia Llamas in-n-out!?😏

Yes 😛😝😜
