摘要
环状管网管径的确定不应按枝状管网计算,而应根据消防用水量和竖管的数量经计算确定。本文针对环状管网改进计算方法,由于考虑到了每条竖管的流量,使得计算流速更接近于实际运行时的流速,避免了传统方法的计算流速偏大导致选泵过大的缺点。
To determine the pipe network diameter should not be on the branch network computing, but according to the amount of fire water and standpipe calculated. Aiming at the improvement of calculation method of loop network, this paper considering each standpipe flow, so the calculation velocity is closer to the actual operation flow, avoids computing the velocity of traditional methods of partial large pump too much, can reduce the occurrence of overpressure condition.
