摘要
本文根据水泵特性和管路阻力特性,从理论上阐述了水泵在变负荷运行时,用传统的节流调节造成较大能量损失的原因,而采用变频调速法则具有明显的节能效果。
On the basis of the properties of water pump and pipe-line resistance, this paper explains in theory that when the pump worksunder varying load, there will be great energy loss caused by traditionalthrottle government, but in reverse some energy save will be practiced byspeed regulation through frequency-change in stead.
