和平电站装机容量为3×1600瓩,水头270米,引水压力钢管全长682.4米,内径0.8米,通过流量2.4米~3/秒,流速4.77米/秒,最大正水击压力升高值43.2米,为保证压力钢管安全工作,在钢管末端装置了A37H--40型弹簧式安全阀,其公称直径为100毫米,公称压力为40公斤/厘米~2,工作压力为32～40公斤/厘米~2,机组于1977年10月投入运行,1978年11月我们对机组及压力钢管进行水阻甩负荷试验.钢管末端最高水压达34公斤/厘米~2,安全阀动作灵敏,压力钢管无异常现象.
The installed capacity of Heping Power Station is 3 × 1600 瓩 and the head of water is 270 meters. The length of pilot water pipe is 682.4 meters, the inner diameter is 0.8 meters, the flow rate is 2.4 meters to 3 seconds, the flow rate is 4.77 meters per second and the maximum positive water hammer pressure is increased 43.2% Meters, in order to ensure the safety of the pressure pipe, the A37H - 40 spring - type safety valve is installed at the end of the pipe. The nominal diameter is 100 mm, the nominal pressure is 40 kg / cm ~ 2 and the working pressure is 32 ~ 40 kg / cm ~ 2, the unit was put into operation in October 1977, and we carried out water resistance load rejection test on the unit and the pressure pipe in November 1978. The maximum water pressure at the pipe end reaches 34 kg / cm ~ 2, the safety valve is sensitive and the pressure pipe is free Anomalies.
