Storage indoors
To store the machine indoors:
•
If the machine is stored in its transportation package, make big enough holes
on the sides of the transportation package so that the D-end and ND-end of
the machine are accessible.
•
If the protection made by the manufacturer has been removed, protect the
unpainted surfaces such as shaft extensions, coupling discs, coupling halves
and jacking screws with suitable anti-corrosion agent.
•
If the machine has been delivered in fully assembled condition, turn the rotor
approximately 10 revolutions once per every 3 months to maintain a
protective oil film or grease on the bearing surfaces.
Storage outdoors
To store the machine outdoors:
•
Take all the measures described in Storage indoors above.
•
Cover the machine completely with a big enough waterproof cover.
•
Remove the side and end covers of the machine.
•
Protect the bare shaft surfaces and non painted parts with anti corrosive agent.
2.2.3 Very long term storage (over 6 months)
Clean all the protected surfaces listed in Chapter 2.2.1. Short term storage (less
than 2 months) and Chapter 2.2.2. Long term storage (2-6 months), and renew the
anti-corrosive treatment every 12 months. Otherwise follow the instructions for
shorter storage periods.
2.2.4 Rolling bearings
Apply the following measures:
•
Rolling bearings should be well lubricated during storage. Acceptable grease
types are presented in Chapter 2.1.5. Bearing plate. For bearings without re-
lubrication option this action is neglected.
•
Turn the rotor 10 revolutions every three months to keep the bearings in good
condition.
Remove any possible transport locking device during turning the rotor.
•
Machines may be provided with a locking device to protect the bearings
against damage during transport and storage. Check the bearing locking
device periodically. Tighten the transport locking device according to the
axially locating bearing type, see Table 2-1. Tightening torque for horizontal
machines (lubricated screw).
NOTE: A too high tightening torque on the transport locking device will damage
NOTE: The type of bearings used are found on the bearing plate, see Chapter
the bearing.
