Ultrahigh-pressure continuous pre-mixed abrasive jet system

The ultrahigh-pressure continuous pre-mixed abrasive jet system comprises a hydraulic pump, an outlet of the hydraulic pump is connected with a first water pipe and a second water pipe through a shuntvalve, and the first water pipe is sequentially connected with a first flow control valve, a fourth one-way valve, a mixing chamber and a high-pressure nozzle in series. The second water pipe is communicated with a water inlet of the first electromagnetic directional valve after flowing through the second flow control valve, two water outlets of the first electromagnetic directional valve are communicated with the two abrasive mixing devices after flowing through the second electromagnetic directional valve and the third electromagnetic directional valve respectively, and the two abrasive mixing devices can alternately conduct automatic feeding, so that continuous feeding of abrasives is achieved. Mixed abrasives do not need to be added without disassembling the pressure tank. 本实用新型公开了一种超高压连续前混合磨料射流系统，包括液压泵,液压泵出口
