【摘要】 本文目的在于提出脉冲泵的理论;介绍气脉冲模型泵试验结果;展望脉冲泵的发展前景及其可能应用的场合。 脉冲泵是利用脉冲波的单流管效应来获得单向连续出流的新型泵。泵中流态单一,能量转换效率高,单级扬程范围较广。泵出流连续、流量较大而无气蚀危险。 1976年以来,我们研制了气脉冲模型泵。通过反复试验及性能测试使理论基本得到证实。更多还原

【Abstract】 The purpose of this paper is to suggest the theory of the pulse pump; to introduce the experimental results of the models of the air-operated pulse pump; to estimate the perspective of the development of the pulse pump and its possible applications.The pulse pump is a new-type pump, in which the fluid successively flows out in one direction by means of the pulse effect in the uniflow pipe.The flow pattern is simple in this pump, so that the efficiency of the energy transformation would be higher,and the head range obtained in single stage may be wider as well. In this pump the flow is successive, so that the flow rate would be higher without: any danger of cavitation.We have investigated and made the models of air-operated pulse pump since 1976. The theory suggested have been basically proved by the repeated tests and measurements.更多还原
