The 3500 Generator Sets consist of an engine, a generator and the control systems.Intended Use
This Power Generator is intended to be used to generate electrical power.Description (Engine)
The 3500 Series Generator Set Engines includes an 8 cylinder engine, a 12 cylinder engine, and a 16 cylinder engine. These engines are four stroke cycle with direct injection. Each cylinder head has two inlet valves and two exhaust valves. The camshaft uses mechanical lifters and pushrods to actuate the rocker arms and valves.The engines are supplied with fuel by direct fuel injection. An electronic governor and an actuator controls the fuel injection pump output in order to maintain the engine rpm that is selected by the operator.Fuel is metered and pumped by a fuel injection pump to the fuel injection nozzles (one per cylinder). The automatic timing advance provides the best fuel injection timing over the full range of engine rpm.Inlet air is filtered by the air cleaner. The air is compressed by the turbocharger before the air enters the cylinders. The turbocharger is driven by the engine exhaust. The standard engine is turbocharged and aftercooled. The coolant for the aftercooler is circulated by the jacket water pump.The cooling system consists of the following components:
Centrifugal pumps
Four water temperature regulators which maintain the engine coolant temperature to 93 to 107 °C (200 to 225 °F)
An oil cooler
A radiator which incorporates a shunt systemThe engine lubricating oil is cooled and the engine lubricating oil is filtered. The engine lubricating oil is supplied by a pump that is driven by a gear. If the oil viscosity is high or if the oil cooler and oil filter elements become plugged, bypass valves provide unrestricted flow of lubrication oil to the engine.Engine efficiency and engine performance depend on adherence to proper operation and maintenance recommendations. Use the recommended fuels, lubrication oils, and coolant. Pay special attention to the air cleaner, to the fuel system, to the lubrication system, and to the cooling system maintenance. Refer to this Operation and Maintenance Manual, "Maintenance Interval Schedule" for more information on maintenance items. Description (Generator)
The SR4B brushless generator can be used with the following loads: mixed loads of motors and lights, SCR-controlled equipment, computer centers, installations of communications and petroleum drilling applications.The generator set packages can be utilized for prime power generation or standby power generation. SR4B generators are utilized in three-phase full-wave excitation and regulation. The generators are either four pole or six pole design with six lead configuration or twelve lead configuration. The generators are capable of producing electrical power in either 50 Hz or 60 Hz applications.
