【Abstract】 In view of the increasingly severe service conditions of high-pressure piston pump, the paper points out that most scholars study the influence of complex working conditions of fluid field and temperature field coupling on reliability and life of plunger pump, and summarizes and discusses the wear mechanism, lubrication characteristics and structure optimization of key friction pairs of plunger pump at home and abroad. Through comparative induction of different research methods, the key disciplines restricting the development of high-pressure piston pump are pointed out Question. On this basis, the prospect of the coupling of convection solid heat is prospected. It provides theoretical reference and technical guidance for high-pressure plunger pump to play a greater role in high-end equipment, military machinery, aerospace and other fields in China.更多还原
