Diesel generating set is a small power generation equipment, which refers to diesel engine as fuel and diesel engine as the motive force to drive generator power generation. The diesel generating set is usually composed of diesel engine, generator, control box, fuel tank, starting and controlling storage battery, protection device, emergency cabinet and other components. The whole can be fixed on the base, located in use, and can also be installed on the trailer for mobile use.
Diesel generating set is a discontinuous operation power generation equipment. If it runs over 12h continuously, its output power will be less than 90% of the rated power.
Although the diesel generator power is low, but because of its small size, flexible, lightweight, complete, convenient operation and maintenance, it is widely used in mines, railways, field sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments, as a backup power source or temporary power supply. In recent years, the newly developed unattended automatic emergency power station has expanded the scope of the use of this kind of generator.
Diesel generating sets are classified by the size of the output power of the generator, and the energy of the unit is from a variety of specifications of 10kW-750kW. Each kind of specification is also divided into protective type (equipped with super speed, high water temperature, low oil pressure protection device), emergency type and mobile power plant type. The mobile power station is also divided into high speed cross-country type and low speed normal mobile type which can match the speed of automobile at the speed of time.
The modern diesel generating set consists of a diesel engine, a three-phase alternating current brushless synchronous generator, a control box (screen), a radiator tank, a coupling, a fuel tank, a muffler and a common base. The axial flywheel shell and a diesel engine generator front end cover with a shoulder positioned directly connected together, and a cylindrical elastic coupling flywheel by direct drive generators to rotate, the way of connection by screws fixed together, so that the two are connected into a steel body, the crankshaft of the diesel engine and the generator rotor concentricity in the specified range.
