今天水泵已在各个经济部门得到广泛应用,种类之多不胜列举。这里,我们着重介绍几种农用水泵。大家知道,我们要保证农业上的稳产增收,总离不开“水”。利用水来灌田基本上有两种方式:一种是利用“水往低处流”的自然条件实现自流灌溉;另一种是利用水泵使水往高处流,实现机械化灌溉。目前我国使用的农用水泵类型不下六、七种之多,它们各有适用的特点,因此,必须根据使用要求和当地条件来选用,才能充分发挥它们各自的特长和效能。
Today, water pumps have been widely used in various economic sectors. Here, we focus on several types of agricultural water pumps. As we all know, we must ensure that the steady output increase in agriculture cannot be separated from “water”. There are basically two ways to use water to fertilize fields: one is to use natural conditions of “water flowing down to low flow” to realize gravity irrigation; the other is to use water pumps to make water flow high and realize mechanized irrigation. At present, there are no more than six or seven types of agricultural water pumps used in China, and they have their own applicable characteristics. Therefore, they must be selected according to the requirements of use and local conditions in order to give full play to their respective specialties and effectiveness.
