PETROL ENGINE
COMPRESSOR
SYMPTOMS
PROBABLE CAUSE
CORRECTIVE ACTION
The compressor does not
load.
1-The intake valve remains closed.
1-Check the valve. If necessary, replace the
damaged parts with the spare parts kit.
2-The solenoid valve does not work
accurately
2-Check the solenoid valve. If necessary, replace it.
3-Losses on the pressure line.
3-Check pipes and cables. If necessary, replace
them.
During idling phase, the
compressor does not
discharge pressure from
separator tank
1-The solenoid valve does not work
accurately.
1-Check the solenoid valve. If necessary, replace it.
2-The calibrated nozzle is clogged.
2-Remove the calibrated nozzle. Clean or replace it.
Compressor capacity or
pressure lower than usual
standard.
1-The air filter is clogged.
1-Remove the air filter. Clean or replace it.
2-The intake valve does not open.
2-Check the valve. If necessary, replace the
damaged parts with the spare parts kit.
3-Air loss from safety valve.
3-Replace the valve.
Compressor keeps on
loading over working
pressure: safety valve opens
1-The solenoid valve does not work
accurately.
1-Check the solenoid valve. If necessary, replace it.
2-Clogged separator filter.
2-Replace the separator filter.
Compressor overheating.
1-Insufficient cooling.
1-Check the cooling system. Check coolant level on
tank.
2-Dirty oil
2-Replace it with new oil.
3-Oil level is too low.
3-Check coolant level on tank and if necessary, add
oil.
4-Clogged-up cooler or pipe connection
4-Clean cooler and pipes.
5-The thermostatic valve does not work
correctly.
5-Check the thermostatic valve. If necessary,
replace the damaged parts with spare parts kit (
Contact MEA for parts required)
6-Clogged oil filter
6-Replace the oil filter
During unloading phase,
pressure increases up to
safety
valve opening
1-The intake valve remains open.
1-Check the valve. If necessary, replace the
damaged parts with spare parts kit.
2-The calibrated nozzle is clogged.
2-Remove the calibrated nozzle. Clean or replace it.
Oil leakage from intake
1-The intake valve does not work properly
1-Check the valve. If necessary, replace the
