美国卡特皮勒Caterpiller发电机日本国际久保IMC发电机发电机组肩负着为国民经济以及人民生活用电提供发电成套设备的重任，所以它在很长一段时间内还会占据着很重要的位置。而伴随着时代的进步社会的发展，原有的那种发电机组显然已经不适合社会的需要。笨重、耗油、噪音、污染 所以未来发电机组的发展方向应该是节能、环保、轻型化、小型化、美观大方。这样才能发挥出发电机组的潜在X势。 发电机通常由定子、转子、端盖.机座及轴承等部件构成。
定子由机座.定子铁芯、线包绕组、以及固定这些部分的其他结构件组成。
转子由转子铁芯(有磁扼.磁极绕组)滑环、(又称铜环.集电环).风扇及转轴等部件组成。
由轴承及端盖将发电机的定子，转子连接组装起来，使转子能在定子中旋转，做切割磁感线的运动，从而产生感应电势，通过接线端子引出，接在回路中，便产生了电流。
汽轮发电机 与汽轮机配套的发电机。为了得到较高的效率，汽轮机一般做成高速的，通常为3000转／分（频率为50赫）或3600转／分（频率为60赫）。X站中汽轮机转速较低,但也在1500转/分以上。高速汽轮发电机为了减少因离心力而产生的机械应力以及降低风摩耗，转子直径一般做得比较小，长度比较大，即采用细长的转子。特别是在3000转／分以上的大容量高速机组，由于材料强度的关系，转子直径受到严格的限制，一般不能X过 1.2米。而转子本体的长度又受到临界速度的限制。当本体长度达到直径的6倍以上时,转子的X二临界速度将接近于电机的运转速度，运行中可能发生较大的振动。所以大型高速汽轮发电机转子的尺寸受到严格的限制。10万千瓦左右的空冷电机其转子尺寸已达到上述的极限尺寸,要再增大电机容量,只有靠增加电机的电磁负荷来实现。为此必须加强电机的冷却。所以 5～10万千瓦以上的汽轮发电机都采用了冷却效果较好的氢冷或水冷技术。70年代以来，汽轮发电机的X大容量已达到130～150万千瓦。从1986年以来，在高临界温度X导电材料研究方面取得了重大突破。X导技术可望在汽轮发电机中得到应用，这将在汽轮发电机发展史上产生一个新的飞跃。Xiamen generator acquisition market, the old generator site recycling of Xiamen, Xiamen, Xiamen, the acquisition of the old generating units 13606035861 recovery, recycling, Xiamen generator phone recycling network in Xiamen best generator Cummins generator Cummins generator brand

Japan, U.S. Caterpillar Caterpiller generator generator units IMC International Okubo shoulder electricity for the national economy and peoples living the important task of providing power generation equipment, so it is in a very long period of time will occupy a very important position. And with the progress of the times and social development, the original is clearly the kind of generator is not suitable for the needs of society. Heavy, fuel consumption, noise, pollution, so the future direction of the generating units should be energy saving, environmental protection, light, small, nice. Generating units in order to play a potential advantage.
Generator is usually the stator, rotor, end cap. Stand and bearings and other components composition.
The stator from the base. Stator core, line winding, and the fixed part of the other structural parts of these components.
Rotor from the rotor core (a magnetic choke. Pole winding) slip ring (also known as copper ring. Collector ring.) Fan and shaft and other components.
By the bearing and cover the generator stator and rotor assembly connected together, so that the rotor can rotate in the stator, so the movement of magnetic induction lines cut, resulting in induction potential, leads through the terminal, then in the loop, it produced a current.
Turbine and steam turbine generator package. In order to obtain high efficiency, typically made of high-speed turbine, usually 3000 r / min (frequency 50 Hz) or 3600 r / min (frequency of 60 Hz.) Nuclear power plants in the turbine speed is low, but also 1500 rev / min or more. High-speed turbine centrifugal force generated in order to reduce the mechanical stress and reduce the consumption of air friction, the rotor diameter is generally done is relatively small, the length is relatively large, that is, using thin rotor. Especially in the 3000 r / min or more large-capacity high-speed unit, the material strength of the relationship between the rotor diameter is strictly limited, generally can not exceed 1.
2 meters. The length of the rotor body has been critical speed limits. When the body length of more than 6 times the diameter of the rotor of the second critical speed would be closer to the motor running speed, running a large vibration may occur. Therefore, the size of large high-speed rotor is severely restricted. About 10 million kilowatts of its rotor size air-cooled motor has reached the limit of size, again increasing the motor capacity, and only by increasing the load to achieve the electromagnetic motor. So we must strengthen the motor cooling. So 5 to 10 million kw are used to turbo the better the cooling effect of hydrogen or water cooling technology. 70
Since the generator has reached the maximum capacity of 130 to 150 million kilowatts. Since 1986, the high critical temperature super-conducting materials research has made a major breakthrough. Superconducting technology is expected to be applied in the generator, turbine generator that will create a new history of the development leap.
