General description of generator set
1 General description of the generator and its identification
The design of this generator set is a complete combination and provides superior and reliable performance. This article gives a brief description of the main parts of the generator.
Each generator has a nameplate. Basically nailed to the peripherals of the alternator. The information on the nameplate is used to identify the generator and its operating characteristics. These data should include the model, body number, output voltage, phase sequence and frequency, the output power is expressed in KVA or KW, and the specified power. For reference, these materials will be repeated in the technical data sheet attached to this manual. The model and serial numbers are unique and will not be repeated. These numbers must be provided when purchasing accessories and warranty services.
2 diesel engine
Diesel generator is the source of power for the generator set. It is specially designed and manufactured for this generator set with safe and reliable performance. Diesel engines belong to the 4-stroke or 2-stroke compression ignition type for heavy industry and are matched to provide stable power supply. The package includes a cylindrical air filter, a turbocharger on some diesel engine models, and a mechanical or electronic governor to closely control the speed of the diesel engine.
3 engine power system
The power system of the engine is a 12 or 24 volt negative grounded DC corona system according to the model. It includes a starter motor, battery and battery rack. In some large generators, this project may be placed on the floor near the generator. Battery charger. Most generators are proposed to provide one or two lead-acid batteries, which will be discussed in detail in Chapter 10 of this manual. This machine can also be used with other types of batteries under customer requirements.
4 cooling system
The engine cooling system includes a radiating water tank, an axial fan and a thermostat. The alternator has a separate fan to cool its components. Note that the airflow passes through the alternator first. Then it passes through the engine and finally through the radiator water tank.
The output power is generated by a protective cover dripping to protect the peripherals, a brushless automatic, self-regulated alternator, and a control box installed on top of it.
6 Fuel tank and chassis
Both the engine and the alternator are mounted on a heavy steel chassis. Except for the largest units, under normal circumstances there is a fuel that can hold full load and start up for 8 hours. If there is no fuel tank on the bottom frame, a separate fuel tank must be provided.
7 shock absorber
The generator is equipped with shock absorbers, which are specially designed to reduce the transmission of vibration to the foundation when the generator starts. These shock absorbers are installed between the engine/alternator feet and the chassis. However, in larger generators, the engine/alternator is fixed on the base frame, while the shock absorber is provided to the customer and installed between the base frame and the foundation.
8Muffler and exhaust system
The exhaust muffler is randomly attached to be installed. This muffler and exhaust system can reduce noise and directly discharge exhaust gas outdoors.
9 control system (identification)
There are several control systems and control panels, one of which is installed on each machine to control operation and output, and to protect the unit from damaging the machine due to incorrect operation. Chapter 9 of this manual provides detailed information and signs to help distinguish different control systems.
10 Power air switch
In order to protect the alternator, a power switch suitable for related models and related power output is installed in an independent switch box. In some cases, the switch may be installed together with the automatic transfer conveying system or the control panel.
