Bare surfaces
Apply a protective covering of TECTYL 506 (Supplier:
VALVOLINE) or similar to all bare parts of the shaft
outside the enclosure e.g. coupling, shaft surfaces,
etc.
Surfaces on the bedplate not covered by the motor
feet or shims, and the edges of the shims themselves,
are to be protected with paint as called for in the
project specifications.
In case “non-contact” vibration probes should be
provided, extreme care has to be taken for
protection of the shaft machined surface under the
probes, especially if the machine is installed
outside.
Remember that any corrosion on the machined
surface under the probes will irreversibly damage
the measuring system!
Piping
The piping within the scope of the motor supply were
cleaned, and dried by blowing through with warm air
before packing. It must be ensured that they are still
clean and dry before the machines are conserved.
Space heaters
Space heaters must remain switched on in order to
avoid condensation within the machine. Periodically
check that they are operating.
Openings
If there are any openings where cables are not
connected up to terminal boxes, or piping to flanges,
etc. these are to be temporarily sealed up.
Inspections, record
The conservation measures are to be given a final
check and recorded together with the date of the
beginning of the conservation period.
Thereafter carry out regular inspections, the first after
six months and record results.
Renew conservation measures when and where
necessary.
Preparing the machines for commissioning
Restore machines to their original state (refer to
check list below). Carry out through visual inspection
of each machine and strictly follow instructions given
in the operating manual.
Keep full individual unit records of all work performed
in preparing the machines for service. Such records
can be of vital importance both to the commissioning
engineer and to the user to enhance trouble-free
operation.
Apply a protective layer of TECTYL 506 (supplier:
VALVOLINE) or similar product on all the exposed
bare surfaces, like the shaft expansion, the coupling
etc.
