High-speed turbo-generator in order to reduce the mechanical stress due to the centrifugal force generated by the wind and reduce wear, the rotor diameter is generally done quite small, the length of the relatively large, which uses thin rotor. Especially in 3000 r / min or more large-capacity high-speed unit turbine manufacturer, because the relationship between the strength of the material, the rotor diameter is severely restricted, usually not more than 1.2 meters. The length of the rotor body has been critical speed limit. Diesel generator set is a combination of diesel and synchronous AC generator made. Diesel power is limited by the maximum allowed limit turbine parts mechanical load and thermal load, and therefore need to allow continuous operation of the provisions referred to the maximum power rated power; diesel engine can not exceed the rated power, otherwise it will shorten its life, even may cause an accident. (1) diesel engine rated power; Weifang generator sets national standards on diesel engine nameplate rated power is divided into the following four categories; 1) 15min power: the diesel engine is allowed to run 15min maximum power. Short period of time might be overloaded and requires calibration acceleration power, such as cars, motorcycles and other diesel engine rated power. 2) 1h Power: i.e. diesel 1h allow continuous operation of the maximum effective power. Such as tractors, locomotives, ships and other diesel engine rated power. 3) 12h power: the diesel engine to allow continued operation of the maximum effective power 12h, that we often say that the rated power. Such as power plant units, engineering machinery and diesel engine rated power. 4) Continuous power: the diesel engine continued to run the maximum allowed time has power.
