7 Compressor Suction and Discharge Pressure Test
7.1 General Spec. of compressor
7.1.1 Disconnect all fittings from the compressor. Cap the Suction port. Install a LP
gauge on the process port. Install a HP gauge on the discharge port. Start the compressor
and monitor the gauge readings the discharge pressure should build to 17 bar in HP gauge.
And the compressor should pull a -0.85 bar vacuum in LP gauge.
Shut off the compressor. The LP gauge and HP gauge values should hold for 30
seconds to one minute. If not, proceed to step-7.3, then repeat test. If no improvement,
replace the compressor.
7.1.2 If the compressor has weak suction or discharge, check the oil level and add oil if
necessary. If the oil level is okay or oil was added with no improvement, replace the
compressor
