【摘要】 变速泵在开式和闭式管路中的节能效果不同 ,引起这种差别的原因是开式系统受水的静压作用改变了泵的效率。分析了开式管路系统中变速泵的节能效果并给出了计算实例更多还原

【Abstract】 The effects of energy saving of variable speed pumps in the closed circuit is different from those in the open pipeline system. The reason is that there is a static head in the open system causing the pump efficiency varying. Analyses the energy saving effects of variable speed pumps in open systems and provides calculation examples.更多还原
