Diesel-powered generator is used where there is no connection to the grid, or as emergency power in case of grid failure, as well as for more complex applications such as peak tripping, grid support and grid output. ATO portable silent diesel generators for sale, from 3 kW (3.5 kVA) to 10 kW (12.5kVA) rated output, powered by 4 stroke air cooled direct injection diesel engine. They are flexible, equipped with four wheels for easy movement, big fuel tank ensure a long operation time. Three-phase and single-phase diesel generators are available for home use and can be widely used in industry, mines, railroads, field sites, road traffic maintenance, and factories, businesses, hospitals and other sectors as well.
In short, the diesel generator drives the generator to run. In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel injected by the fuel injector. Under the upward extrusion 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, the volume expands rapidly, and the piston is pushed down, which is called work. Each cylinder performs work in a certain order, and the thrust on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous alternator and the crankshaft of the diesel generator coaxially, the rotor of the generator can be driven by the rotation of the diesel generator and then using the principle of electromagnetic induction, the generator will output the induced electromotive force, and the closed load loop will generate current.
Only the most basic working principle of the generator set is described here. A series of diesel generators and generator controls, protection devices and circuits are also required to obtain a usable, stable power output.
As we all know, fuel cost and availability, durability, safety, low maintenance and reliability directly affect the daily life of generators, therefore, the ATO portable diesel generator needs to have the following advantages:
A three-phase diesel generator is a new type of power generation equipment, with a lightweight design, reliable quality and a wide range of applications. Many customers feedback that the three-phase diesel generator sometimes has a lacks motor phase during its use of it. What is the reason for the phenomenon?
The reason for the phase loss of the three-phase diesel generator motor is that the power supply line (usually a contactor or a circuit breaker) does not supply the three-phase voltage to the motor at the same time, or the line is disconnected. The phenomenon is that if the motor can rotate at no-load, it will instantly heat up and hum and the rotation will be weak; when it is overloaded, it will just hum and instantly heat up. If the power is not turned off in time, the motor will be burned.
For a three-phase induction motor, the normal operation should be three proportional AC current flow into the three proportional stator windings to produce a circular rotating magnetic field. When the three-phase current is missing one phase, the motor will appear an abnormal operation phenomenon. The main reasons for the motor to cause a phase failure are the following situations.
Diesel generators are also ideal for industrial use when there is a power outage or power shortage. It should be noted that, for efficiency and safety, a diesel generator of suitable power must be used.
Natural gas generators are another ideal option for emergency use. One of the reasons natural gas generators are some of the best is because they don't need to be ready to store gas to get electricity, just have piped gas and that's it. Of all the non-renewable resources available for power generation, natural gas generators are one of the most efficient sources of power.
When an emergency actually occurs, generators can provide a reliable and stable power supply for enterprises. However, for some large enterprises, factories, construction sites, hospitals, computer data centers, financial institutions and other industries that require a more reliable power supply, a diesel generator is the ideal choice.
