A diesel generator is a self-generating device that uses a diesel engine as the driving force to drive an AC alternator for power generation. Working Principle Of A Diesel Generator: Converting mechanical energy from a diesel engine into electrical energy by AC alternator

What's A Diesel Generator?

Diesel generator is a type of self-generating supply equipment in self-owned power plants, which is a small and medium-sized independent power generation equipment. Compared with other power generation equipment, diesel generator has the characteristics of compact size, small footprint, high thermal efficiency, quick start, flexible control, and convenient fuel storage.

Diesel Generator Application

For areas such as telecom stations, mining areas, forest areas, field operations, national defense projects, and other areas that can not be supplied by the city power grid, a diesel generator is used as an independent self-generating power equipment for continuous power supply.

For areas with city power, which require high-reliability requirements for power supply that do not allow power outage, the diesel generator is used as an emergency backup power source for the industries. Once the city power outage occurs, a stable AC power supply can be quickly provided by the diesel generator.

Diesel Generator Components

• The diesel generator is composed of a diesel engine, AC alternator, control panel, radiator, electrical output box, fuel storage tank, muffler, and common base bed. Most main components are installed on a common base bed welded with steel, which is easy to move and install.
• The axial connection between the flywheel housing of the diesel engine and the front cover of the alternator is directly integrated through shoulder positioning, and the SAE standard rigid flywheel connection plate is used to drive the alternator to rotate directly from the flywheel. This kind of connection method is fixed together by screws, connecting the two into a rigid body, ensuring that the concentricity of the crankshaft of the diesel engine and the rotor of the alternator is within the specified allowable range.
• To reduce the vibration of the diesel generator, shock absorbers or rubber shock absorbers are usually installed at the connection between the main components such as the diesel engine, alternator, radiator, control panel, and the common base bed.

Diesel Engine: A diesel engine is a type of internal combustion engine, which is an energy conversion device that converts the heat energy released from fuel combustion into mechanical energy. The diesel engine is the power part in the Working Principle Of A Diesel Generator, generally composed of a crankshaft connecting rod mechanism and body components, valve distribution mechanism and intake and exhaust system, diesel supply system, lubrication system, cooling system, and electrical system.

Alternator: The alternator is connected to the diesel engine's crankshaft and converts the mechanical energy produced by the diesel engine into electrical energy. The alternator is the energy and electricity output part in the Working Principle Of A Diesel Generator. The AC alternator includes the main rotor, stator, exciter rotor, bearing, cooling fan, AVR, and rectifier
