基于西门子变频器的恒压供水系统的设计

摘要

In the system of water supply, power of the pump was determined according to the maximum runoff, but the actual runoff with various factors change, often much lower than the maximum runoff. To reduce the flow of time, typically regulating baffle or valve to adjust the flow. This control mode when the desired flow decrease, the pressure would increase, the decline of axial power limited, excess water pump power would lead to increased pressure cause great loss of energy.%在供水系统中,水泵的功率是根据最大流量来选择的,但实际使用中流量随各种因素变化,往往比最大流量小得多.要减少流量时,通常情况下调节挡板或阀门开度来调节流量.这种控制方式当所需流量减少时,压力反而会增加,轴功率的降低有限,过剩的水泵功率将导致压力增加造成很大的能量损耗.
