水泵，作为一种通用水力机械，已应用到了国民经济的各行各业，特别是用途广泛的离心泵。但在许多单位，由于对水泵维护不够或长时间使用，水泵没有了铭牌，不知其型号，对其性能的了解、使用变得尤为困难。下面，就无铭牌的水泵的型号，介绍一种简易的推求方法，供同行参考。 Water pumps, as a kind of general hydraulic machinery, have been applied to all walks of life in the national economy, especially the wide range of centrifugal pumps. However, in many units, due to insufficient or long-term maintenance of the pump, the pump does not have a nameplate. However, it is especially difficult to know its type and performance. Next, there is no nameplate pump models, introduced a simple method of estimation for peer reference.
