Section IV. VIBRATION
17-24. A certain amount of vibration is inherent in the
operation of any generator set. If vibration is
transmitted to surrounding areas, the noise level
increases. The engine generator is mounted directly to
the skid; therefore, twelve vibration isolators are
recommended to be installed between the skid and
foundation. Figure 17-4 illustrates the recommended
type of isolator.
17-25. When the generator set is installed within a
building, all fuel, coolant, exhaust, and electrical
connections must have flexible sections so that vibration
is not transmitted along these lines. See Figure 17-5.
Section V. AIR REQUIREMENTS FOR UNHOUSED 500 KW GENERATOR SETS INSTALLED WITHIN A BUILDING
17-26. A ventilation system must be installed to provide
adequate air at the generator set to remove heat
radiated by the engine generator and supply combustion
air for the engine.
17-27. When installing the ventilation system the
following factors should be considered:
Location of inlet and outlet air ports.
Method of actuation of inlet and outlet louvers.
Routing of exhaust air duct.
Placement of discharge louver.
Whether radiator and fan assembly will be
separated from the generator set.
17-28. The air inlet and outlet must be in the same
room position to allow convection air flow from the inlet,
across the unit, and exhausted through
