Definition

A generator is a mechanical device that converts other forms of energy into electrical energy. A diesel generator is a combination of a diesel engine and a generator (usually an alternator) to generate electrical energy. Diesel compression ignition engines are usually designed to run on fuel, but some types are suitable for other liquid fuels or natural gas.

Basic Structure

The basic structure of a diesel generator is composed of a diesel engine and a generator. The diesel engine drives the generator to generate electricity.

The basic structure of a diesel engine: consists of cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings and flywheels. The diesel engine of the diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine. I will only talk about the basic working principle of a single-cylinder four-stroke diesel engine: the start of a diesel engine is to turn the crankshaft of the diesel engine by manpower or other power to make the piston sealed at the top of the cylinder In reciprocating movement up and down. The piston completes four strokes in motion: intake stroke, compression stroke, combustion and power (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 are increased, and the compression process is completed. When the piston is about to reach its peak, the fuel injector sprays the filtered fuel into the combustion chamber as a mist and mixes it with high-temperature and high-pressure air. Work stroke. After the work stroke is completed, the piston moves from bottom to top, the exhaust valve opens to exhaust, and the exhaust stroke is completed. The crankshaft rotates half a turn per stroke. After several working cycles, the diesel engine gradually accelerates into work under the inertia of the flywheel.

Principle of the diesel generator

In short, the diesel generator drives the generator.

In short, the diesel generator drives the generator.In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel sprayed from the fuel injector. Under the upward squeeze of the piston, the volume is reduced and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, and its volume expands rapidly, pushing the piston down, which is called ‘work’. Each cylinder performs work in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. Install the brushless synchronous alternator coaxially with the crankshaft of the diesel generator, and then the rotation of the diesel generator can be used to drive the rotor of the generator. Using the principle of "electromagnetic induction", the generator will output induced electromotive force through a closed load circuit. Can produce electric current.

Only the most basic working principle of the generator set is described here. To obtain usable and stable power output, a series of diesel generators and generator control, protection devices and circuits are also needed.

Standard diesel generator are widely used in general installations in computer rooms. The unit is mainly composed of diesel engine, generator, control system, frame, shock absorber, cooling system, fuel supply system, and output protection switch.

Soundproof Silent Diesel Generator 

Silent diesel generator  is widely used in outdoor or indoor places with special requirements for environmental protection that require protection and noise reduction. It is mainly composed of a standard unit, a soundproof enclosure, an air inlet and exhaust noise reduction device, and an exhaust noise reduction device. Its main features It is a combination of soundproof housing with sound insulation and sound absorption layer, air inlet and exhaust channels for noise reduction treatment, and exhaust adopts a combination of industrial and residential mufflers to reduce its high-frequency and low-frequency noise respectively. The noise of standard sound-proof unit is generally 78-85dB(A), and the noise of super-sound-proof unit is generally 70-78dB(A). The super soundproof unit adopts more stringent control measures on noise emission on the basis of the standard soundproof unit, such as adopting the design of labyrinth air intake and exhaust passages.

 Diesel generator on trailer

 Diesel generator on trailer are widely used in telecommunications, television broadcasting, highways, emergency rescues, power supply, and military and other power emergency situations that require high speed, mobility and reliability. The unit is mainly installed in the car compartment, and can be equipped with an electric cable winch, multiple output sockets and mechanical (or hydraulic) outriggers, and it can also easily realize the parallel use of multiple vehicle-mounted mobile power stations. The general noise of the vehicle-mounted mobile power station is 70~80dB(A).

The main application

Power supply for daily use

Although diesel generator sets have low power, they are widely used in mines, railways, field construction sites, road traffic maintenance, and factories, enterprises, hospitals and other departments due to their small size, flexibility, light weight, complete supporting facilities, and easy operation and maintenance. 

Emergency Power Supply

Diesel generator sets are used in places that are not connected to the grid, or used as emergency power sources in the event of a grid failure, and for more complex applications such as peak tripping, grid support and grid output.
