From Robert Poirier of

> I think i know what is the problem
>
> If compressor is a multi-stage piston compressor, If the the
compressor
> trip on high dicharge temperature (mandatory on all compressor) after
a few
> 10 minutes of operation the problem could be one of the following
>
> 1- not sufficent cooling water circulation in the intercooler or
intercooler
> is durty with silk (commond problem with water comming from
evaporative
> cooling tower).
>
> On next start up of compressor check, temperature of CO gas at the
> intercooler outlet and dischage of water temperature. If both are
gradualy
> increasing until shut down of compressor, you got the nature of
problem. See
> if you can increase water flow to the intercooler or clean the
intercooler.
>
> 2 Trip on high discharge temperature or overload of themotor. the
inlet
> pressure of CO gaz at the compressor decrease gradualy. this would
increase
> the compression ratio of the compressor, the amperage of motor would
> increase and the dicharge temperature of all stages.
>
> As Gordon mention, with more information we can determine the nature
of the
> problem and do the necessairy correction.
