四会县威整电站,安装两台HLA_(73)—WJ—85水轮机,单机容量6,000千瓦,工作水头130米,转速1,000转/分。 威整电站是引水式径流电站,由于上游水土流失严重,水流挟带大量泥沙进渠过机。根据一次汛期暴雨后取样实测,水流平均含沙量为1.17公斤/米~3;枯水期久旱后为0.12公斤/米~3。因此,水轮机每年约有八个月在挟沙水流中运行,其过流部件受到泥沙的磨损破坏相当严重。 1~#机组自1974年5月投产,至今已报废转轮两只,前、后盖板及迷宫盖板一套,导水
Weicheng Power Station in Sihui County installed two HLA_ (73) -WJ-85 turbines with a single capacity of 6,000 kilowatts and a working head of 130 meters with a speed of 1,000 rev / min. Wei power plant is a water diversion runoff power station, due to serious soil erosion in the upper reaches, water carrying a large amount of sediment into the canal through the machine. According to a sampling after rainstorm in a flood season, the average sediment concentration of water flow is 1.17 kg / m ~ 3; while the dry season is 0.12 kg / m ~ 3 after a long drought. As a result, turbines operate in sediment-laden flow of water for about eight months of each year, and their over-current components are severely damaged and damaged by sediment. 1 ~ # unit put into operation in May 1974, has so far scrap two wheels, front and rear cover and a set of labyrinth cover, water guide
