Leaking around Pressure Switch. Ordered & replaced switch but still leaking


Some pressure switches have a valve that reliefs the compressor head pressure when the motor stops and closes the head pressure relief valve when the motor runs.
There is a check valve that keeps air pressure from coming back to the compressor head and the relief valve.
I think the check valve is leaking tank pressure to the relief valve and compressor head.
The check valve is where the pressure switch mounts on to and it mounts threaded on to the compressor tank.
Try replacing the check valve

Compressor reaches upper pressure limit of 120 psi but does not shut down or increase in pressure. When manually shut off at near 120 psi it will hold pressure for extended time.


Hi

Here are a few things to check, you may have already checked some of these.

Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.

Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.

Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.

Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.

Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
It will contribute to not shutting off the compressor motor thru the use of the pressure switch.
A worn cylinder will also contribute to the problem of pressure build-up.

Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.

My compressor runs and builds pressure but, with nothing touched all of a sudden does not produce the same amount of pressure as before, it will not run my printing machine. What should I check?


Does the compressor have enough CFM to run the printing machine. Will the compressor build up pressure and shut off if you close the discharge valve at the tank. Your printing machine may simply be using to much air. If the above items are not the case you may have a faulty check valve in the receiver tank or valves going bad in the LP or HP heads. The valves may also simply have carbon build up or dirt of some type not allowing the valves to seat properly. I would start at the check valve. One way to check the check valve is to see if you have air blowing from the bleed off line at the pressure switch all the time. Another way to check is loosen the fitting at the High Pressure head an see if you have air blowing continously. Caution do not remove the fitting at the head completely. If the check valve is bad you will have high pressure air blowing until the receiver tank is drained.

Compressor runs until overload release valve opens (pressure at 130 psi) and then air escapes until pressure lowers to 100 psi..Then motor begins to restart, but will not , due to 100 psi and kicks breaker...


There is a check valve between the compressor and tank, and there is also an 'unloader valve' which blows the pressure off the compressor so that it starts under little load. I think your check valve is stuck open and the unloader valve is blowing tank pressure off.. and when the compressor tries to start it's starting against the pressure in the tank.

So check/replace/thaw the check valve and you'll be good to go. It's generally at the tank where the line from the compressor head goes into the tank, it'll be between the two somewhere.

Sounds like the compressor has failed -- probably the valve -- tear down and rebuild is probably the solution, or replace compressor, or just buy another unit. My nature would be to tear it down and see what's going on.

Compessor trips circuit


IT SOUNDS LIKE YOUR COMPRESSOR IS NOT UNLOADING WHEN IT SHUTS DOWN. YOU SHOULD HEAR AN AIR RELIEF SOUND TYPICALLY ON THE SIDE OF THE PRESSURE SWITCH WHEN IT SHUTS DOWN. ITS A SMALL VALVE WITH A TIRE VALVE THAT THE LEVER HITS AND RELIEVES THE PRESSURE FROM THE DISCHARGE LINE AND THE TOP OF THE PISTON.

YOUR CHECK VALVE COULD BE BAD LETTING PRESSURE BACK UP BUT IT WOULD BE BLOWING AIR OUT ALL THE TIME WHEN SHUT DOWN.

IF YOU THINK THE VALVE OR SWITCH IS WORKING AND WANT TO CHECK IT, LET THE COMPRESSOR BUILD UP AND SHUT DOWN, LISTEN FOR THE AIR RELIEF,IF IT DOESNT THEN CRACK THE DISCHARGE LINE AND SEE IF THERES ANY PRESSURE, MANUALLY RELIEVE THE PRESSURE THEN USE SOME AIR AND SEE WHAT HAPPENS. REPAIR VALVE ON THE SIDE OR CHANGE PRESSURE SWITCH $30-40.00. HOPE THIS HELPS. PLEASE REPLY. JODY
