In order to obtain higher efficiency, generally made of high-speed steam turbine, usually 1500 r / min (frequency of 50 Hz) or 1800 rev / min (frequency 60 Hz). Nuclear power plant in the lower turbine speed, but also in 1500 r / min or more. High-speed turbo-generator to reduce mechanical stress due to the centrifugal force generated by the wind and reduce wear, the rotor diameter is generally made smaller, the length is relatively large, that is, using thin rotor. Large-capacity high-speed unit, particularly in 3000 r / min or more, the oil pressure sensor, the relationship between the strength of the material, the rotor diameter is strictly limited, usually no more than 1.2 meters. The length of the rotor body has been critical speed limit. Continuous running for more than 12h, the sensor, the output power will be less than about 90% of the rated power of the diesel generator is generally single-cylinder or multi-cylinder diesel four-stroke diesel engine, here I only talk about the basic principles of the work of a single-cylinder four-stroke diesel engine: Engine start the diesel engine crankshaft is rotated so that the piston reciprocates up and down on top of a closed cylinder through human or other power. Four stroke piston complete in motion: the intake stroke, compression stroke, combustion, and for power (expansion) stroke and an exhaust stroke. When the piston moves down from the upper intake valve opens, the air filter filtered fresh air into the cylinder to complete the intake stroke.
