9. Possible malfunctions and the ways of their elimination
The list of possible malfunctions and the ways of their elimination are given in table 5.
Table 5
Name of faultiness
Possible reason
Method of elimination
Compressor’s productivity
slowdown
Distortion of the junctions’
density or air channels
Spot the leak, squeeze the
junctures, change the air
channels.
Air filter loading
Clean the filter element
Belt slip, due to insufficient
tension or fouling
Strain the belt, cleanse it.
Air leak from the pressostate’s
valve – constant “hissing”,
when the compressor is still
stopped.
Air leak because of wearing or
blocking of the check valve.
Unscrew the hexahedral
valve’s head, clean the sad-
dle or the seal disk, or
change them.
Motor overheating and engine
shutdown in the process of op-
eration.
Malfunction of the engine’s
ventilator
Check the ventilator, change
it if necessary.
Insufficient level of oil in the
compressor’s casing
Check the quality and the
level of oil, add some oil, if
necessary.
Continuous compressors opera-
tion with maximal pressure and
air consumption , which trig-
gers heat protection
Bring down the loading, air
consumption and pressure,
restart the compressor.
Compressor’s shutdown in the
process of operation
Feed network distortion
Check the feed network.
The compressor vibrates in the
process of operation, it drones,
after restart the compressor’s
engine doesn’t start, the engine
drones.
No tension in one of the feed
circuit’s phases.
Check and ensure the
feeding of the circuit.
Oil excess in compressed air
and receiver
Oil level in the casing is above
normal
Adjust it to the middle level.
In case of detection of other malfunctions it is necessary to consult the manufacturer.
