This paper introduces the hydrodynamics theory related to water wave pump. Water wave pump is a new type pump, which uses the particular quality of water wave and re-divides the inflow energy to increase the pressure of one part of the inflow water with the rest water flowing away freely. The research and development of such a pump is of importance and significant value and profitable social interest in that it can fully utilize the residual energy of natural source in industrial and civil water circle systems. Through hydrodynamies research and calculation, a series of valid design parameters were obtained and the predicted results achieved. 相似文献

可控高扬程水锤泵模型试验 总被引:1,自引:1,他引:0
为解决现有实验室厂房高度不足,无法对水锤泵高扬程的性能进行模型试验的技术难题,提出了一种高扬程水锤泵模型试验的设计方法。根据水力学原理,通过在试验平台的扬水管线路上,并联增设可调节局部阻力元件的技术,实现了水锤泵扬程的控制和调节。利用该技术开发了可控高扬程水锤泵实验平台,并对研制的新型水锤泵进行模型试验,验证了该技术用于研究水锤泵高扬程性能的可调节性和稳定性。试验结果表明,新型水锤泵的效率最高可达70%;以日扬水量大于1 m3作为临界点,可将水扬送至42倍作用水头的高度,大于同尺寸水锤泵的32倍。 相似文献

Water hammer following the tripping of pumps can lead to overpressure and negative pressure. Reduction in overpressure and negative pressure may be necessary to avoid failure, to improve the efficiency of operation and to avoid fatigue of system components. The field tests on the water hammer have been conducted on the pump rising pipeline system with an air chamber. The hydraulic transient was simulated using the method of characteristics. Minimizing the least squares problem representing the difference between the measured and predicted transient response in the system performs the calibration of the simulation program. Among the input variables used in the water hammer analysis, the polytropic exponent, the discharge coefficient and the wave speed were calibrated. The computer program developed in this study will be useful in designing the optimum parameters of an air chamber for the real pump pipeline system. The correct selection of air chamber size and the effect of the inner diameter of the orifice to minimize water hammer have been investigated by both field measurements and numerical modeling. 相似文献
