The principle of the invention is as follows: the air cylinder drives the connecting rod to press downwards, the connecting rod drives the glue pressing disc to press downwards, the glue in the glue storage tank is pressed by external force, and the pressure of the glue can be increased to 4-6 bar; the pressurized colloid enters the shell through the colloid inlet 51 and moves along the direction shown by the arrow, when the colloid needs to be pumped out, the piston rod moves downwards under the action of the pneumatic motor, the piston rod drives the sealing rod to move downwards, the gap between the conical part of the valve seat and the conical opening of the valve seat is sealed, the backflow of the colloid is prevented, when the piston rod is further pressed downwards, the colloid entering the space between the shell and the piston rod is pressed downwards by the sealing ring and enters the hollow cavity in the upper part of the piston rod along the direction shown by the arrow to be discharged, and the change of the pressure section area is large, so the output pressure of the high-pressure piston pump can reach 300 bar.

When the starting motor drives the piston rod to move upwards, the sealing structure of the lower end sealing port and the sealing rod is opened, and the colloid enters the shell and is ready to be pumped out for the second time.
