对单节点加压泵管路并联供水系统直接用伯努利方程、管道阻力特性和节点连续性方程建立了求解工况参数的一个新的数学模型，给出了工况参数的数解和图解两种方法，例举了应用实例。
A new mathematical model for solving the operating condition parameters was established by directly using the Bernoulli equation, the pipe resistance characteristics and the node continuity equation for the single-node pressurized pump pipeline parallel water supply system. Several numerical solutions and diagrams of the working condition parameters were given. Two methods, examples of applications.
