| 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。 |

| A design method for model experiment of hydraulic ram pump with high-lift was presented to meet the demands of its performance testing in laboratory with insufficient height. Based on the hydraulic principle， control and regulation of the delivery heads of the hydraulic ram pump has achieved by adding adjustable local resistance components in parallel in the delivery pipes. With this technology， an adjustable and high-head experimental platform has been developed， and experiments for the newly developed hydraulic ram pump were conducted on the platform. The adjustability and stability of the platform were verified. The results show that the efficiency of the novel hydraulic ram pump reaches 70 %. Taking the daily delivery flow larger than 1m3 as a critical point， the novel hydraulic ram pump is able to lift water up to the height which may be 42 times of the supply head，about 32 times of the height lifted by the Rife hydraulic ram pump with similar size. |
