Double head gas-taking compressor

The utility model relates to a double head gas-taking compressor, which is mainly composed of a machine base, a motor, a gas storing tank, gas cylinders, connecting rods, a crank shaft and an energy saving rod. The utility model is characterized in that the machine base is provided with two gas cylinders, each of the gas cylinders is provided with a gas inlet valve and a gas outlet valve, and pistons are arranged in the gas cylinders. The top of the machine base is movably connected with the energy saving rod through a rotary shaft, both sides of the energy saving rod are movably connected with connecting rods, the other end of each of the connecting rods is connected with the piston in the gas cylinder, and the middle part of the energy saving rod is provided with a sliding chute. A handle of the crank shaft is arranged in the sliding chute, and the shaft head of the crank shaft is connected with a main shaft of the motor through a belt. When the crank shaft is driven by the motor to rotate for a circle, the compressor is aerated for twice, and the aerating time is more once than the traditional one head type gas compressor. Therefore, the aerating speed of the utility model is high, and the energy saving rate is from 49.05% to 70.25%. Such as a 1.5m< 3 > gas compressor, the traditional one head type gas compressor needs a 15KW motor to drive, but the utility model only needs a 6KW motor to drive, and the electrical energy can be saved by 9KW per hour. The utility model is suitable for gas supply stations for industries such as drilling, mining, factories, traffic, etc.
