高压气提水泵耗气量与提水量关系试验研究

在我国一些偏远地区还存在着结构性缺水的问题,设计出利用河流中本身蕴藏的水力能实现泵水功能的装置,是解决这一问题的途径之一。试验的研究对象是一套提水装置,它可将自然界的低落差水力能转换成高压气体,然后再用产生的高压气体实现将水提到更高扬程的目的。通过对试验数据以及观察到的现象的分析,探究了耗气量与提水量之间的关系,并考虑进气管直径、回水高度、淹没比、泵管外径等因素的影响,得到了耗气量与提水量的相互作用规律,为该装置的实际工程应用提供科学试验依据。

Experimental study on the relationship between the gas consumption and the capacity of water delivery of high pressure gas pump

There are still problems of structural water shortage in some remote areas of China One of the ways to solve this problem is to design a device that utilizes the inherent hydraulic power in the river to realize the function of pumping water. The object of the study is a set of water-lifting device that converts natural low-drop hydraulic energy into high-pressure gas and then pump the water to the higher lift with the resulting high-pressure gas. Through the analysis of experimental data and observed phenomena, the relationship between the gas consumption and the capacity of water delivery is explored, and the influence of the factors such as the diameter of the inlet pipe, the height of the returning water, the submerged ratio and the outer diameter of the pump pipe are taken into account, and the law of interaction between gas consumption and water withdrawal is obtained. The experimental conclusion can provide scientific basis for the practical engineering application of the device.
