Figure 14: Gas Compressors with Multiple Safety Devices
pressure switch set to shut down the compressor at
3-5 PSIG below proper pressure may be installed at
the oil pump to shutdown the compressor in case of
lubrication failure. A 5-10 second delay timer should
be used to lock out the switch at start-up.
Pressure Safety Valve
– Pressure safety relief valves
prevent dangerous over-pressurization by relieving
system pressure when compressed air/gas reaches the
maximum operating pressure of the system. Failure to
provide properly sized pressure relief valves can cause
property damage, personal injury, or death. Pressure
safety valves are preset by the manufacturer and the
settings should not be changed by anyone other than
the manufacturer or an authorized service facility.
Any line leading to or from a compressor that can be
blocked by a valve or other device, whether during
normal operation or during a failed operation, MUST
be equipped with a safety relief device. The safety
valve must be of a material compatible with the gas
being compressed, and must be able to handle a
fl ow
in excess of the maximum fl ow of the compressor.
For toxic or fl ammable gases, the relief valve must
have a plumbed outlet that is piped to a safe release
area (outdoors,
fl are stack, etc), per local or federal
codes.
PLUMBING OF AIR BOOSTER AND
GAS COMPRESSOR PACKINGS
Hycomp gas compressors utilize piston rod gas
packings to maintain a pressure on the backside of
the compression piston, creating a fully reversing
piston rod load, as well as sealing the gas within the
booster itself.
Hycomp piston rod packings are bi-directional, but
must be properly arranged for speci
fi c applications.
The packing set is pinned together to prevent rotation
