摘要
介绍了作者正在研制的水波泵目前所涉及到的流体力学理论。水波泵是一种巧妙地综合气波增压器和水锤泵功能的全新的水泵,它通过合理利用水波动力的特殊性质,将来流中的总体能量进行重新分配,使一部分来流水提高到所需的高压力,而其余部分水则降到较低的压力,即完成一个大多数能量向部分来流水转移的过程。该泵的研制对于充分开发和利用自然水力资源或工业与民用水循环系统的废弃能量,具有良好的经济价值及社会效益。文中在介绍水锤泵工作原理的基础上,分析了水击动力现象的产生和利用方法,再通过流体力学理论研究与计算,得出了水波泵一系列有用的设计参数,设计计算表明,水波泵的设计研究在流体动力学理论研究和运用具有突破性的意义,并达到预期的效果。
Hydromechanics theory concerning with water pumps is proposed. Water wave pump combines the functions of Air Wave Charger and Water Hammer Pump to show fine performance, where the total energy of inflow is redistributed to heighten the pressure of a part of the flow to the desired level whereas for the rest of flow a low level of pressure is maintained, which causes moving water with high energy to reach to a higher place. On the basis of the working principles of water hammer pumps, water hammer motive power with applications is investigated, a series of parameters for water wave pump design are proposed. The computational results verified the validity and flexibility.
