Diesel Generator Structure Diagram and Introduction

1. Diesel Generator Structure:

The basic structure of a diesel generator set is composed of a diesel engine, an alternator (electric head), a control box, a steel base and a cooling water tank. The diesel engine drives the alternator (electric head) to generate electricity and converts kinetic energy into electrical energy.
The basic structure of a diesel engine: it consists of cylinders, pistons, cylinder heads, intake valves, exhaust valves, crankshafts, bearings and flywheels.
The diesel engine of the diesel generator is generally a multi-cylinder four-stroke, and the piston completes four strokes in motion: intake stroke, compression stroke, combustion and work (expansion) stroke and exhaust stroke.
When the piston moves from top to bottom, the intake valve opens, and the fresh air filtered by the air filter enters the cylinder to complete the intake stroke.
The piston moves from bottom to top, the intake and exhaust valves are closed, the air is compressed, the temperature and pressure increase, and the compression process is completed. When the piston is about to reach the top, the injector sprays the filtered fuel into the combustion chamber in a mist form and mixes with the high-temperature and high-pressure air to immediately ignite and burn itself. power stroke.

2. Main Uses of Diesel Generators:

Diesel generator set is a kind of power generation equipment, which refers to the power machinery that uses diesel as fuel and diesel engine as the prime mover to drive the generator to generate electricity.
The whole set is generally composed of diesel engine, generator, control box, fuel tank, battery for starting and control, protection device, emergency cabinet and other components.
The whole can be fixed on the foundation for positioning and can also be mounted on a trailer for mobile use. Diesel generator set is a non-continuous operation power generation equipment. If it runs continuously for more than 12 hours, its output power will be about 90% lower than the rated power.
And because the cost of power generation is higher than that of the power grid, diesel generators are used for power generation in places beyond the reach of the power grid, or for daily power generation and emergency power generation in various homes, offices, large, medium and small enterprises.
