Hydraulic plunger pump

The invention discloses a hydraulic plunger pump, and relates to the technical field of hydraulic pumps. The hydraulic plunger pump comprises a bottom plate, a piston rod and a piston rod, the two oil cylinders are symmetrically and vertically arranged on the bottom plate; the supporting assembly is fixedly connected with the tops of the two oil cylinders; the plunger pump is arranged at the tail end of the supporting assembly; the glue barrel is fixedly connected with the bottom plate and located under the plunger pump; the discharge hole is formed in one side of the glue barrel; the two oil cylinders drive the supporting assembly to move up and down and synchronously drive the plunger pump to move, so that the plunger pump is separated from the glue barrel or makes extrusion contact with the glue barrel. The problems that in the prior art, the energy efficiency is low, the motor reliability is poor, a pneumatic motor is frozen, and the capacity of an air compressor is insufficient are solved. 本发明公开了液压柱塞泵，涉及
