Abstract: With the advancement of material science and manufacturing technology, water hydraulic technology using freshwater or seawater as the working medium has developed vigorously. As the power core of water hydraulic system, the research direction of water hydraulic pump tends to be miniaturization, high power density, high pressure, intellectualization, electro-hydraulic integration, which is widely used in construction machinery, food and medicine, fire safety, ocean engineering. Combined with application requirement, the micro-small water hydraulic bidirectional pump with different structures in domestic and abroad are presented, and the performance characteristics of different types of micro-small water hydraulic bidirectional pump are analyzed with the main application occasion listed. Compared with the research status at domestic and abroad, it is found that the domestic micro-small water hydraulic bidirectional pump has the problems of larger volume, lower working pressure and lower product maturity. The key problems that friction and wear of bidirectional water lubricating material, sealing, production cost, lack of structure and technological innovation in micro-small water hydraulic bidirectional pumps need to be solved urgently. The potential main application prospects of micro-small water hydraulic bidirectional pumps are proposed. This article provides a reference for the development of micro water hydraulic pump technology.
