Alignment in operation
The topic addressed here is the alignment in operation.
Alignment with the machine stopped
the alignment, under normal conditions, in an industrial installation is routine work, without special technical difficulties. With the help of a laser equipment becomes a very simple intervention.
Alignment in operation in an emergency condition
While in an industrial installation the need to urgently start a machine, normally be associated with economic consequences arising from production losses, in a vessel, stopping a machine can put people's lives at risk.
Furthermore, there are situations where there is no easy access to the machines to be aligned (ex. submarines where machines can be behind pipelines) or there are no means, or knowledge, to carry out the alignment under optimal conditions (ex.: fishing vessel).
despite this, the machines have to be put into operation, with existing means.
Alignment procedure in operation
Alignment with machines in service is a technique that has long been known and is often used by those who have no other means to do it, and it is carried out as follows:
- Place comparators on all shoes to track vertical movements (optional)
- The machine to be moved is the one that is free (normally the electric motor)
- Lighten the legs slightly (as vibrations can go up slightly)
- The engine at this point must move by itself in the correct direction..
- By attempts to find the best position.
