Abstract
The utility model provides a rotor-type compressor and a gas-liquid separator thereof. The gas-liquid separator comprises a gas inlet pipe, an upper shell, a filtering net component, a barrel body, a lower shell and a gas discharging pipe. The gas-liquid separator is characterized in that the axis of a hole of the gas discharging pipe brazed at the bottom of the lower shell is not coincided with the common axis of the lower shell and the barrel body; the bending direction of the bending part of the gas discharging pipe outside the lower shell is towards one side of the common axis of the lower shell and the barrel body. According to the utility model, the gas discharging pipe penetrates out of the hole of the lower shell of the barrel body and is arranged at one side separated from a compressor body, so that the distance between a brazing seam of the gas discharging pipe and the compressor body and a brazing seam between the gas discharging pipe and the lower shell of the barrel body can be effectively increased; compared with the original gas-liquid separator brazed on the rotor-type compressor body, when the gas-liquid separator provided by the utility model is brazed on the rotor-type compressor body, the influence on the brazing seam between the gas discharging pipe and the lower shell of the gas-liquid separator becomes less.
