Installing the Compressor
The following instructions apply to ‘bare’ compressors; adapt as
necessary if the compressor forms part of a package unit.
If the compressor has been in prolonged storage, carry out the
instructions described under 8.2. Taking the Compressor out of Storage,
before installation takes place.
9.1.
Lifting the Compressor
Attach lifting tackle to a pair of eyebolts (full thread) screwed into the
compressor suction/discharge flange face as shown in Fig 10. A crane or
block and tackle will be required to lift the compressor. Check that the
lifting equipment is stout enough to take the weight by referring to
Appendix 1 Compressor Data.
Fig 10 Lifting the Compressor
Check that the compressor mounting points on the baseframe are
completely free from rust, dirt or burrs. Lift the compressor and make the
same check on the underside of the compressor’s four mounting feet.
As the compressor is being positioned, insert the holding-down bolts
through the mounting feet into the baseframe. When all four bolts are in
position, set the compressor down on the baseframe and remove the
lifting gear. Screw the nuts onto the holding-down bolts and tighten
CAUTION
To prevent the nuts working loose during operation, use
nuts with nylon inserts (stiff nuts) or secure with Loctite
thread sealer.
9.2.
Making Connections
Pipeline connection sizes are detailed in Appendix 1 Compressor Data.
(a)
Carefully purge the holding charge of nitrogen from the
compressor.
NOTE: the holding charge of nitrogen must be removed
before the compressor is run.
(b)
If the economiser facility is to be used, remove the blanking plugs
from the economiser connections. Connect the economiser lines
to the ports.
(c)
If the compressor is fitted with liquid injection cooling, connect the
liquid supply line to the flanged connections on the main casing.
