Diesel Generator Set Introduction

The diesel generating set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the motive force to drive the generator to generate electricity, and the kinetic energy is converted into the power mechanical and thermal energy power mechanical equipment.

The diesel engine drives the generator and converts the energy of the diesel into electrical energy. A diesel engine is a type of internal combustion engine that injects diesel fuel into a cylinder and mixes air to burn a heat engine that converts thermal energy into mechanical energy. That is, the fuel gas expands by pushing the piston into linear motion, and the crankshaft rotates the crankshaft through a crank mechanism. In order to output mechanical work. In diesel engine cylinders, the clean air filtered by the air filter is fully mixed with the high-pressure atomization diesel fuel injected by the injector. Under the compression of the piston line, the volume is reduced and the temperature rapidly rises to reach the ignition point of the diesel fuel. Diesel is ignited, the mixture gas burns violently, and the volume expands rapidly, pushing the piston down, called 'work'. Each cylinder in turn performs work in a certain order. The thrust acting on the piston becomes a force that drives the rotation of the crankshaft through the connecting rod, thereby driving the rotation of the crankshaft.

By installing the brushless synchronous alternator coaxially with the crankshaft of the diesel engine, the rotation of the diesel engine can be used to drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator will output the induced electromotive force, and the closed load circuit can generate current. .

A diesel generator is a type of AC power supply equipment for a self-contained power station. It is a small, independent power generation device that uses an internal combustion engine as a power source to drive a synchronous alternator to generate electricity.

Modern diesel generating sets consist of diesel engines, three-phase alternating current brushless synchronous generators, control boxes (screens), cooling water tanks, couplings, fuel tanks, mufflers and public bases to form a steel unit. The axial direction of the flywheel housing of the diesel engine and the front end cover of the generator is directly connected with the shoulder positioning, and a cylindrical elastic coupling is used to directly drive the rotation of the generator by the flywheel, and the connection method is fixed by Screws to make the two They are connected into a steel body, which ensures that the concentricity of the crankshaft and the generator rotor of the diesel engine is within the specified range.

In order to reduce the vibration of the unit, shock absorbers or rubber cushions are usually installed at the joints of the diesel engine, generator, water tank, and electrical control box, etc., with the common base.

The entire generator set is mainly divided into three parts: 1, diesel engines. 2, generators. 3, controller. Subdivision: Base, diesel engine, base fuel tank, generator set, controller, radiator, and noise-proof box. According to the different needs of different places, we put the generator components into fixed and movable trailers, in order to reduce the noise generated by the generator set, reduce the impact on people's work and life, prompting designers to design a power generation with a silent box The unit is a metal box installed outside the generator set with sound-absorbing material inside, so as to protect the generator set around the door and set the doors on both sides of the box. This facilitates the maintenance and control of the generator set. The soundproof box not only greatly reduces the noise generated by the generator set, but also can be placed outdoors. The box is like a house, and it is sun-protected and rain-proof, which saves people the trouble of not having a room as a machine room. Diesel generator components are divided into common power and standby power for common generators and standby diesel generators. The standard power of each generator set is generally 80% of the standby power. We need to use the national power grid according to our different needs. If it is necessary to cut off the power, please use a backup diesel generator set. If you need to operate for a long time, please select a common diesel generator set, and frequently use the diesel generator sets for frequent maintenance. The annual operating time can be more than 300 days. The relationship between common power and standby power is: For example, a user needs a 200 KW diesel generator set, and standby 200 kW diesel generator set standby power is 200 KW*80%=160 KW. That is, the standby power of the 160KW diesel generator is 200KW. Although the diesel generator set has low power, it is widely used in mines, railways, field construction sites, road traffic maintenance, factories, hospitals, hotels, etc. due to its small size, flexibility, light weight, and complete facilities for ease of operation and maintenance. , as backup power and temporary power.
