PART 2 PRODUCTS
2.01 ENGINE
A. Engine shall be watercooled 4 cycle inline or vee type compression
ignition diesel. It shall meet specifications when operating on No. 2
domestic burner oil. The engine shall be equipped with fuel, lube oil,
coolant, exhaust system, silencer, fuel transfer pump, fuel priming pump,
fuel water separator, service run time meter, engine driven water pump,
engine driven alternator for batteries, batteries, instrument/control panel
including: lube oil pressure gauge, tachometer, system voltage, jacket
water temperature gauge, system diagnostics code display, other auxiliary
equipment as may be required for proper operation of the units. Provide
jacket water heater. Provide one at 3 kW each, 208 volts.
B. An electronic governor system shall provide automatic isochronous
frequency regulation. The governing system dynamic capabilities shall be
controlled as a function of engine coolant temperature to provide fast,
stable operation at varying engine operating temperature conditions. The
control system shall actively control the fuel rate and excitation as
appropriate to the state of the generator set. Fuel rate shall be regulated as
a function of starting, accelerating to start disconnect speed, accelerating
to rated speed, and operating in various isochronous or parallel states.
C. The engine/generator set shall be mounted on a structural steel sub-base
and shall be provided with suitable quad spring vibration isolators.
D. Safety devices for protection of the units shall be provided as per the
generator Supplier and shall minimally include: shutoffs for high water
temperature, low oil pressure, overspeed and engine overcrank.
E. Guards shall be provided over all exposed moving parts per OSHA.
2.02 ALTERNATOR
A. The AC generator shall be synchronous, four pole, 2/3 pitch, revolving
field, drip-proof construction, single pre-lubricated sealed bearing, air
cooled by a direct drive centrifugal blower fan, and directly connected to
the engine with flexible drive disc. All insulation system components
shall meet NEMA MG1 temperature limits for Class H insulation system.
Actual temperature rise measured by resistance method at full load shall
not exceed 80 degrees Centrigrade. Supplier shall supply the alternator
suitable for the load. If a lower temperature rise alternator is required then
it shall be provided.
