10.5.2. Installing
The center alignment of engine and Generator set is the most important factor for the
extension of performance and life. Although aligning the center perfectly and accurately
requires only few minutes, it is able to prevent unnecessary mechanical trouble at the future.
1) Bed rail
At the installation of Generator set’s
bed rail, use steel, If the bed rail is
strong enough, the center alignment
of engine with Generator gets worse
so that the excessive vibration may
occur.
2) Supporting
As in the engine installation, the supporting brackets are used even at the installation of
Generator.
The bracket must be solidly fixed at the Generator installing platform and the bed rail.
3) Aligning center
The center alignment of engine and Generator is the most important factor for the
extension of life cycle.
•
Output shaft flange and opponent side flange of Generator should be aligned in their
centers horizontal and parallel direction
•
The adjustment between flange surfaces at the lower part should maintain less than
0.15 mm when the upper part’s surfaces just meet and the deviation around the
circumference should be maintained within 0.1 mm as following figure.
For bed rail is apt to deform for 6 months after initial performance, adjusting the center
should be checked after 1 ~ 2 months.
