Screw Compressor J-series
Appendix 1.3 Tips for Compressor Package Installation
Appendix1-7
With these steps, the coupling of flange motor and compressor and fastening them to the
compressor base is finished.
If there is any gap left between the base and the motor feet, the compressor and
motor spacer can be strained, which may lead not only to abnormal noises and
vibrations but also damage to the bearing or leak from the mechanical seal.
When the compressor is the 280J-series or when the compressor and the motor are coupled
without a motor spacer, the four feet of the compressor and motor must be firmly fastened to the
compressor and motor bases.
In this case, the couplings of the motor and the compressor must be aligned. (For detailed
procedure, refer to the package instruction manual.)
Suction Gas Line Piping
When installing the suction piping to the compressor package, provide pipe supports at appropriate
positions so that the compressor suction flange is not subject to excessive loads.
Any excessive loads to the compressor from the piping may cause compressor
casing deformation, resulting in mechanical problems.
Foundation for Compressor Package
The compressor package must be mounted on a solid floor or foundation. The package must be
firmly fixed to the foundation with anchor bolts after leveling and aligning.
If the package is mounted on a floor or foundation without sufficient
reinforcement, abnormal vibrations may occur from the compressor and/or the
package.
