The invention discloses a hydraulic
gas compressor. The hydraulic
gas compressor comprises a tank A, a tank B and a two-way
liquid pressure pump; the lower parts of the tank A and the tank B are filled with liquid; a tank A liquid inflow and outflow
pipe is arranged at the lower part of the tank A, a tank A air outlet valve is arranged at the upper part of the tank A, and a tank A air
inlet valve is arranged on the tank A; a tank B liquid inflow and outflow
pipe is arranged at the lower part of the tank B, a tank B air outlet valve is arranged at the upper part of the tank B, a tank B air
inlet valve is arranged on the tank B; and two ends of the
liquid pressure pump are respectively connected with the A tank liquid inflow and outflow
pipe and the B tank liquid inflow and outflow pipe. According to the hydraulic
gas compressor, high-pressure liquid is used for compressing air. Compared with a traditional
air compressor, the hydraulic gas compressor has the advantages of highenergy utilization efficiency and
low noise and can generate pure
compressed air free of
oil pollution; the energy efficiency of thehydraulic gas compressor is higher than the standard value specified by an optimal
machine type in the
national standard and reach 20%, and the energy efficiency can reach 30% in a special application occasion free of
oil pollution gas, and thus, great contribution can be made to
energy conservation and emission reduction in the world.
