2.9.6 Removing Fastener & Vibration Absorbers
Certain fasteners and vibration absorbers are mounted on the equipment to protect partial
components from getting damaged and distorted due to bumping, impact, and resonance.
Removal of these fasteners and absorbers is necessary before installation and
commissioning.
2.9.7 Removal of the transportation fixing plate from the compressor
Vibration absorbing cushions are added to the compressor base to reduce the vibration and
noise during the operation of the compressor. However, at times, such a technique cannot
control the vibration during transportation. This may result in loosened connection as well as
cause wear and tear of certain parts.
As a preventive measure, 3 U-shaped fixing plates are added to the 3 compressor bases
during transportation.
•
After the installation process and prior to the beginning of the Commissioning
process, remove the 3 U-shaped fixing plates.
•
Restore the bolts and washers in the reverse sequence of the disassembly process.
The fastening torque of the bolts is approximately (12 +/- 1) N-m.
Refer to the Figure 2-25 in order to view the position of the L-shaped fixing plate on being
fixed to the compressor base.
