摘要
根据泵在不同工况下运行的性能与特点,及泵流量、扬程、功率与转速的关系,通过调速与阀门节流的对比,阐述了调速节能的原理和经济效益,并用实例说明了变频水泵选型时应注意的要点及选择气压罐的必要性,从而实现真正意义上的节能。
According to the operation performances and characteristics, as well as pump delivery, lift, relationship of power and speed under different conditions, and based on the comparison of speed control and valve throttling, the author describes the principle and economic benefit of speed control, and explains attention problems of variable frequency pump type selection and the necessity of selecting pressure tank by using examples, so as to realize energy saving in a real sense.
