description The invention belongs to the technical field of high-pressure hydraulic pumps, discloses a high-pressure pulseless hydraulic pump, and aims at solving the problems existing in the prior art. The high-pressure pulseless hydraulic pump comprises multiple plunger cylinders and a drive mechanism. Plunger rods of the multiple plunger cylinders are driven by the drive mechanism to do reciprocating motion. The number of the plunger cylinders is 2n+m+p. A rodless cavity of each plunger cylinder is connected with an oil inlet pipeline and an oil outlet pipeline, and the flow of the oil outlet pipelinesof the 2n+m+p plunger cylinders is superposed. Each plunger cylinder comprises an oil pressing work segment and an oil suction work segment, and each oil pressing work segment comprises a constant-acceleration oil pressing segment, a constant-speed oil pressing segment and a constant-deceleration oil pressing segment. In the 2n+m+p plunger cylinders, at every moment, n plunger cylinders are in the acceleration oil pressi
