渣浆泵广泛应用在矿山和电厂输送固液混合物其最突出的问题是录的效率较低和寿命短；研究人员一直探讨泵流道中固液两相流动结构，磨损与流动的关系，以期找到提高泵效率和减轻过流部件磨损的途径。但是由于叶轮中两相流动的复杂性，加上实验手段不完备，这方面的工作做起来难 Slurry pumps are widely used in mines and power plants to transport solid-liquid mixtures, the most prominent problem is the record low efficiency and short life expectancy; researchers have been discussing the pump flow channel liquid-solid two-phase flow structure, wear and flow relationship, in order to find Ways to increase pump efficiency and reduce over-flow components wear. However, due to the complexity of the two-phase flow in the impeller and the lack of experimental means, it is difficult to do this work
