摘　　要：为了解决末端用户所需流量不足的问题,提出了在该用户处增设一个中继泵的方案。用数理分析证明了在末端增设中继泵的供热系统中,中继泵运行对系统管网流量的影响存在一个影响最小的状态,即系统中各用户支路流量都将达到最佳运行流量,当继续增加末端用户的运行流量时,势必会导致其他用户的实际流量会低于所需流量,影响其供热质量。In order to solve the problem of insufficient traffic required for end users,this study proposed a solution to add a relay pump at the user.This article uses mathematics analysis that in the heating system of the relay pump at the end,there is a minimum impact on the influence of the relay pump operation on the system of the system,that is,the traffic flow of each user in the system will reach the best operating flow.When continuing to increase the operating traffic of the end users,it will inevitably lead to the actual traffic of other users lower than the required flow and affect its heating quality.
