At present, most hydropower plants close the wicket gate by using the closing law with two or three slopes. In fact, as the unit capacity goes up and the turbine working range of water head be even wider than before, so that the fixed closing law with two or three slopes can't control the unit stability effectively when the big fluctuation transient comes op.

目前，普遍采用导叶两段或三段关闭规律，实践表明，随着水轮发电机组容量的增大和水轮机工作水头范围的增大，这种固定的两段或三段导叶关闭方式不能有效地控制机组在大波动水力过渡过程中的稳定性。

The main products as follow the motorcycle engine; the general engine; the digitalgenerator set; the water pump; the electric motor; thresher; reaper; sheller and themulti-function mini-tiller and so on .

With development of the hydro-electrical in china, the scale of the hydropower station is becoming bigger and bigger, at the same time the hydro-electric generating set also trends large-scale, high-capacity and high-parameter. At this point the vibration problems of hydro-electric generating set has become more prominent, it requires not only found them and solve them in the course of the operation, but also avoid them in the design process.

随着我国水电事业的快速发展，水电站的规模越来越大，同时水轮发电机组也向着高水头、大容量、高参数的方向发展，此时机组的振动问题也日益突出，这不仅要求在运行过程中发现问题，解决问题，更要在设计过程中杜绝问题。

During the process of steam turbine start-up and normal operation, vacuum extraction equipment must run,whether it works normally effects on the vacuum of condenser directly and decide whether turbo-generator can operate safely and economically.
