Cummins Generator Cummins Silent Diesel Generator Set 20kw-1200kw

Working principle:

diesel engine drives a generator and converts the energy from diesel into electricity.

In the diesel cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel oil sprayed by the oil nozzle. Under the extrusion of the piston up, the volume shrinks and the temperature rises rapidly to reach the ignition point of the diesel oil. Diesel is ignited, the mixture of gas intense combustion, rapid volume expansion, push piston down, known as' work '. Each cylinder does work in a certain sequence, and the thrust acting on the piston becomes the force pushing the crankshaft through the connecting rod, thus driving the crankshaft to rotate.

The brushless synchronous alternator is installed coaxial with the crankshaft of the diesel engine, and the rotor of the generator can be driven by the rotation of the diesel engine. Using the principle of 'electromagnetic induction', the generator outputs the induced electromotive force, and the current can be generated through the closed load loop.

Diesel generator set is a type of AC power supply equipment of self-provided power station. It is a small independent power generation equipment, which is powered by internal combustion engine and drives synchronous alternator to generate electricity.

Modern diesel generator set is composed of diesel engine, three-phase AC brushless synchronous generator, control box (screen), cooling water tank, coupling, fuel tank, muffler and common base and other components composed of steel integral. The flywheel shell of diesel engine and the shaft of the front end cover of the generator are directly connected by the convex shoulder positioning, and the elastic coupling of the cylindrical type is directly driven by the flywheel to rotate the generator, and the connection is fixed together by the screw, so that the two are connected into a steel body, to ensure the concentricity of the crankshaft of the diesel engine and the generator rotor in the specified range.

In order to reduce the vibration of the unit, shock absorbers or rubber shock pads are usually installed at the connection between the main components of the diesel engine, generator, water tank and electrical control box and the common base.
