Purpose
Purpose
The purpose of this trouble-shooting guide is to assist you in diagnosing a High Discharge Temperature fault.
Procedure
Procedure
This procedure applies to all units that are currently in service in the field, at a repair shop, and in storage yards.
Before any work is performed a JSA must be completed according to Flogistix procedure along with any customer requirements before any work is started.
Help guide to trouble shooting a High Discharge Temperature Diagnosing High Discharge Temperature
(Gas Engine Drive)
Are you having high discharge temperature faults? Follow this help guide to resolve your issue.
Step 1: First let us start by checking the compressor oil level and condition. If the oil level is low the compressor does not have enough oil to cool the gas. Starving the compressor of oil will cause a high temperature. Having oil with low viscosity will also cause the compressor to overheat. Follow the link below for checking compressor oil viscosity.
Did this correct the high discharge temperature fault? If not, continue to step two.
Step 2: Continue diagnosing the high discharge temperature by checking the thermal couple. The thermal couple is used to read the temperature of the gas after it leaves the compressor, loose terminations or faulty thermal couples can cause a false reading. Verify the temperature by using a temperature reading gun to know the estimated temperature that it should be reading. Verify terminations are tight and nothing is loose on the inside.
Did this correct your issue? If not continue to step three.
Step 3: Check cooling fan belts for proper tension and ensure the belts are in good condition. After checking the belts verify that the cooler has good air flow allowing cooling to take place. Continue diagnosing by checking for a restricted oil cooler (inside or outside). Using a temperature gun, you can monitor the temperature and tell whether the gas is going through the cooler and cooling or having issues being clogged. If cooler is clogged a flush may be necessary.
Did this correct your issue? If not, continue to step 4.
Step 4: Check thermostat operation. All packages should be using a 230-degree thermostat. This means once the compressor oil temperature rises above the 230 degrees the thermostat will open allowing oil flow to through the cooler. By allowing the temperature to rise to operating standards you should be able to feel the heat on the piping change from cool to hot. The supply line to the thermostat will always be hot, the supply line to the cooler will change throughout operation. If supply line to the cooler does not heat up after reaching 230 degrees that means that the thermostat is not opening allowing the oil to cool down before continuing through the system. Thermostat will need replacement if the above applies.
Did this correct your issue? If not, continue to step 5.
Step 5: Next, the compressor could be operating above rated pressure or at excessive ratio. If the compressor is under a load that it is not rated for it will cause temperature issues. Also Restricted cooling oil flow could be causing the issue. For example, having any restrictions in the oil line or having clogged oil filters will cause the compressor to overheat.
If issues continue after using this diagnostic sheet, contact your area lead for further instruction.
