OCCASIONAL DEFECTS
Oil dragged to the air system.
Excessive oil consumption,
requiring refilling.
(Too much oil in the air
system).
Excessive vibration or noise.
Safety valve opens repeatedly.
Attention:
See item 13 - Chapter Safety
Instructions
Water excess in the air/oil tank.
NOTES
When there is a pressure drop in the air system, observe the following details:
- If the operating pressure indicated on the pressure gauge of the compressors SRP 3005 TO 3040 compact is high and at the factory too
low, the problem is significant load loss in the air system.
- If the pressure in the compressor is low and in the air system too, it is possible that the consumption increased due to recent installation
of equipment. In this case, the required air demand is higher than the production.
- Before any actions, trying to find the causes in the compressor, close the discharge valve slowly until the pressure rises close to the ma-
ximum operating pressure and check the motor current.
- If the compressor is aspiring air at full load and the current is close to the rating current, it is likely the problem is not the compressor.
PROBABLE CAUSES
Oil level too high.
Compressor oil foaming.
Leak in the system.
Operating pressure of the compressor below 3.4 barg
(50 psi) for a long time.
Separator element damaged. (In this case, the pressure gauge that
indicates restriction will virtually not indicate any restriction).
Return line of the air/oil separator element clogged.
Long time of operation of the compressor in relief.
Electric motor or unit bearing damaged.
Fan blade broken.
Belts loose or worn out.
Air/oil separator element clogged.
Admission valve stuck.
Safety valve damaged.
Solenoid valve(s) defective.
Minimum pressure valve stuck.
Compressor operating too much above the capacity of
the pneumatic tools.
Fast load and relief cycle. (Turn off some compressor in parallel
