The working principle of diesel generators is to use electromagnetic induction principles

Diesel crankshaft rotates with a generator to rotate power generation, generator has a DC generator and an alternator. The DC generator is mainly composed of a generator shell, a magnetic pole core, a magnetic field coil, an armature, and a carbon brush. The alternator is mainly composed of a plurality of southern and north-star-alternated permanent magnets (referred to as rotors) and silicon cast iron manufacturing and armature coils (referred to as stator) with multiple set coils. DC generators and alternators have different working principles, but eventually reach the target of power generation.

Diesel generator setsIt is a small power generation apparatus that refers to diesel, or the like, with a diesel engine, a power machine, which is powered by a generator, is powered by a carpet. The entire unit is generally composed of a diesel engine, a generator, a control box, a fuel tank, a start and control, a protective device, an emergency cabinet and other components. The whole can be fixed based on the position, and can also be installed on the trailer for mobile.

The diesel generator set is a non-continuous operation of the power generation equipment. If the continuous operation exceeds 12 h, the output power will be lower than the rated power of about 90%. If the user needs to be used for a long time, you need to configure a common-purpose generator set, which is to consider this power decline in a long working unit. The relationship between common power and spare power is: such as the user who needs a 100kW diesel generator set, which is often 100KW * 110% = 110 kW of a diesel generator set. That is, the common power of the alternate 100 kW diesel generator set is 90kW. Although the power of the diesel generator set is low, it is widely used in mining, railway, field construction sites, road traffic maintenance, and factories, corporate, hospitals, etc. due to small power, flexible, lightweight, fully equipped, easy to operate and maintain. As a spare power or a temporary power supply.

A type of diesel generator set is a self-supplied power plant AC power supply equipment is a small independent power generation equipment, powered by internal combustion engines, and drives simultaneous AC generators. The brushless synchronous alternator is mounted with the diesel crankshaft, which can utilize the rotor of the diesel engine with the rotor of the generator. The generator can output the induced electromotive force, and the closed load circuit can generate current. . The diesel generator is combined by the internal combustion engine and the synchronous generator. The zui high-power of the internal combustion engine is limited by the mechanical load and heat load of the components, called the rated power, and the rated power of the AC synchronous generator refers to the rated speed. When long-term continuous operation, the rated power output is typically between the rated power of the diesel output rated power and the synchronous alternator output, referred to as a match ratio.
