摘要(Abstract):

详细介绍了脉动水锤装置的结构及其工作过程,对锤击时柱塞组件的运动以及冲击压力波产生和传播机理进行了分析,分析表明这种水锤装置能够产生的水锤压力包括水锤静压力和冲击压力,并通过试验验证了理论分析的正确性。
In the present paper a pulsating water-hammer apparatus that drives by low-pressure water and takes advantage of the tremendous energy generated by water-hammer is introduced. The structure and working process to the pulsating water-hammer apparatus is elaborated. The movement of the plunger assembly when the hammering occurs and the generating and propagation mechanism of the impacting pressure wave are analyzed. The results show the water-hammer pressure that induced by this apparatus includes water-hammer static pressure and impact pressure,and the experiments verify that the theoretical analysis is correct.
