我省在小型水电站中安装了油压制动装置和落转子信号装置,改善了运行条件,防止了事故的发生。现简述如下:一小型卧式机组的油压制动装置在容量小于1000瓩的小型卧式机组中,一般都不设制动装置,根据运行规程,机组转数低于额定转数的35%以下时,应立即制动,以防磨研轴瓦。我省青龙县水胡同电站曾因机组转数过低,油泵转数不够,造成油压降低,供油不足,油环代油量不够而烧毁轴瓦。因此,自行设计制造安装了简单的
In our province, hydraulic brake devices and rotor-off signal devices were installed in small hydropower stations to improve operating conditions and prevent accidents. The following is a brief description: Hydraulic braking device for a small horizontal unit Generally, there are no braking devices in small horizontal units with a capacity of less than 1000,. According to the operating procedures, the number of rotations of the unit is less than 35 % Of the following, should be immediately braked to prevent grinding bearings. Hydropower Hualong County, Hubei Province, the same water turbine power station was too low due to the number of units, the number of revolutions of the pump is not enough, resulting in lower oil pressure, insufficient fuel, oil ring instead of enough oil and burned bearings. Therefore, the design and manufacture of a simple installation
