atlas copco tow behind compressor keeps blowing off oil pipes

Hi, my atlas copco tow behind compressor keeps blowing off oil pipes, I can run it all day with no problems then start it up the next day and within an hour it blows off an oil pipe.


Is there some form of pressure relief valve that may be sticking or do you have any ideas what could be the problem. Many Thanks Pete

Is this on the compressor, or the engine?

If engine, probably bearing mucked up.

If compressor, maybe oil separator clogged?

Temperature shutdown GX11

by Dale Bletso

Started this morning. When the unit loads, pressure builds normal, but when we start putting a demand on it it will run about 2 minutes and the temp alarm shuts it down.

We have correct oil level.

Blew out the unit cooling fins, changed the oil filter.

Have 2500 hrs on the oil separator.

Room temperature was 80 -90F and has been for the past week with no problems.

Where do I start to look?

All our past issues we have had better luck fixing than the local reps who cost a fortune and never seem quite organized or proficient.

It turned out to be the bypass valve

overtemp?
by: Doug in s.d.ca

is it behaving normally up to shutdown?
If so, perhaps the temperature sensor itself is a fault.
