蒸汽轮机是利用高温、高压的水蒸汽喷射到汽轮边上的叶片上去,推动轮子转动的。这种机器的转速比较高,一般每分钟能达到三千转以上,同时它的功率也可以制造得很大,如我国在解放以后,就制出了十万仟瓦的汽轮机。汽轮机最大的优点,是转动很平稳,因为在这种机器的结构中,没有作直线运动的部件,所以很少震动。现在大的火力发电站里,大多是用蒸汽轮机来作动力的。
Steam turbine is the use of high temperature and pressure of water vapor to the steam turbine blades on the edge to promote the rotation of the wheel. The speed of this kind of machine is relatively high, generally can reach more than 3000 revolutions per minute, at the same time its power can be made very big too, if our country liberated one hundred thousand kilowatt steam turbine. The biggest advantage of a turbine is its smooth rotation, because in this structure of the machine there is no part that moves in a straight line so there is little vibration. At present, most large-scale thermal power stations use steam turbines for powering.
