贵州省凤冈县栓塘水电站装有2台100kW的机组,水轮机为ZD560-LH-60型,电站设计水头9.1m,单机引用流量1.3m~3/S。在压力管道设计中,为了节省造价和方便施工,根据电站水头较低的情况采用了竖井式浆砌石压力管。设计中将压力管布置在前池与厂房中间,使前池外墙、厂房后墙及压力管成“三位一体”,从外面看不到压力管(见附图)。此外,为了减少水头损失,特将压力管的断面放大为
There are two units of 100kW installed at Fengtang County Hydropower Station in Fenggang County, Guizhou Province. The turbine is ZD560-LH-60. The designed head of the power station is 9.1m and the flow quoted by a single unit is 1.3m ~ 3 / S. In pressure piping design, in order to save the cost and to facilitate the construction, according to the lower head of the power plant used shaft masonry pressure pipe. In the design, the pressure pipe is arranged in the middle of the forecourt and the factory so that the outer wall of the front pothole, the back wall of the factory building and the pressure pipe become a “trinity”, and the pressure pipe can not be seen from the outside (see attached drawings). In addition, in order to reduce the head loss, especially the pressure pipe section enlarged to
