长期以来,井泵配套主要是按定扬程和定流量即按静态目标选配水泵,未考虑抽水效益与成本的变化,这样就很难使机井工程获得最高经济效益,有时甚至难筹恢复再生产的资金。本文推荐的方法,不仅可消除上述缺点,而且还充分地考虑了在井泵配套中,因机井用途不同和地下水位多变的特征。文中并附有对最佳出水量和最佳扬程的计算程序,以代替繁杂易误的手算。 For a long time, the well pump is mainly matched with the fixed head and fixed flow, which means that the pump can be selected according to the static target without considering the benefit and cost of pumping, which makes it hard to get the highest economic benefit in the well engineering and sometimes it is difficult to recover the regenerative funds. The proposed method not only eliminates the above shortcomings, but also takes full account of the features that are attributed to the different uses of the well and the fluctuating groundwater level in the well pump package.
