Research progress on hydraulic ram pump of high-efficiency and energy-saving performance

In order to clarify the technical development and application status of hydraulic ram pump, the development history of hydraulic ram pump technology, and briefly introduces the basic structure of hydraulic ram pump were reviewed. On this basis, it expounds the efficiency calculation method of hydraulic ram pump, and combs the development of theoretical design method of hydraulic ram pump. Then, the research and development status of hydraulic ram pump at home and abroad was summarized, and the fundamental reasons for the limited development of hydraulic ram pump in China are put forward. It is pointed out that simplifying the manufacturing and assembly process, developing large-scale hydraulic ram pump manufacturing technology, and developing lightweight and split hydraulic ram pump are the key points of future development. Then it is concluded that the system para-meters and structural parameters are the main factors affecting the hydraulic ram pump. Finally, the practical application status of hydraulic ram pump at home and abroad is compared and analyzed. It is proposed that the development and application of hydraulic ram pump should be based on the theoretical model of the whole operation process of hydraulic ram pump considering the dynamic opening and closing process of discharge valve and delivery valve, and the manufacturing technology of hydraulic ram pump suitable for different groups or objectives should be developed. The research results provide a certain reference for expanding the application scope of hydraulic ram pump and improving the manufacturing technology of hydraulic ram pump in China.
