The utility model relates to a novel high-performance hydraulic ejector which comprises a body, a pressing plate and a nozzle assembly, the pressing plate is installed on the body, the nozzle assembly penetrates through the pressing plate to be installed on the body, a sealing bush is arranged at the connecting position of the nozzle assembly and the body, and the pressing plate is a ceramic pressing plate and is installed on the body through a bolt. According to the hydraulic ejector, the ceramic pressing plate is arranged near the nozzle assembly, so that the pressing plate has high hardness, high wear resistance and high impact resistance, rotational flow erosion damage caused by high-speed sand-carrying fluid can be greatly reduced, compared with a conventional hydraulic ejector, the working life can be prolonged from about 10 sections to more than 20 sections, and the service life of the hydraulic ejector is also prolonged. 本实用新型涉及一种新型高性能水力喷射器，包括本体、压板及喷嘴总成，所述压板安装在本体上，所述喷嘴总成穿过压板安装在本体上，所述喷嘴总成与本体连接处设有密封衬套，所
