Abstract
The utility model discloses a combined pneumatic compressor and relates to the field of gas compression. The combined pneumatic compressor comprises a mechanical compression device and a high-pressure compression device, wherein a compression cylinder in the high-pressure compression device comprises an A cavity, a B cavity, a C cavity and a D cavity. When the combined pneumatic compressor compresses gas, low-pressure gas is compressed into medium-pressure gas through the mechanical compression device, the medium gas is compressed into high-pressure gas through the high-pressure compression device and then the high-pressure gas is discharged through the A cavity or the D cavity, and gas in the B cavity or the C cavity is introduced into the mechanical compression device to be compressed again. Liquid can not be mixed in the gas compression process, and thus the gas quality obtained after the gas is compressed is ensured. The gas compression process is fast and the working efficiency is high. Moreover, gas does not easily escape to pollute the external environment when the low-pressure gas is compressed, and thus safety is ensured.
