Hydraulic reciprocating compression air pump with quantified and variable pressurization functions

Abstract

A hydraulic reciprocating air pump with the quantified and variable pressurization functions comprises a middle power reciprocating cylinder, a left compression cylinder and a right compression cylinder. The left compression cylinder and the right compression cylinder are connected to the two ends of the power reciprocating cylinder. A piston of the left compression cylinder divides the left compression cylinder into a first working cavity and a second working cavity. A piston of the right compression cylinder divides the right compression cylinder into a third working cavity and a fourth working cavity. The cylinder diameter of the left compression cylinder is equal to the cylinder diameter of the right compression cylinder in the variable pressurization function. Air inlet valves of the first, second, third and fourth working cavities are each provided with a manual ejector rod. Exhaust valves of the four working cavities are connected in parallel and connected with an air outlet. Suction valves are connected in parallel and connected with an air inlet. The cylinder diameter of the left compression cylinder is not equal to the cylinder diameter of the right compression cylinder in the quantified pressurization function, the exhaust valves of the four working cavities and the suction valves are connected in series in different modes to obtain two pressurization effects, and parallel connection two-level pressurization and series connection three-level pressurization are achieved. According to the hydraulic reciprocating air pump, the cylinder diameters of the left and right compression cylinders are changed, and the series and parallel connection loops of the suction valves and the air inlet valves are changed, so that high pressure or super-high pressure of the gas compression pump is easy to achieve.
