ABSTRACT:
A water-lubricated compressor has a discharge on-off valve in a discharge channel located between a discharge port of a compressor body and a water separating/recovering unit. A water circulation on-off valve is disposed in a water circulation channel located between a water cooler and a water supply portion in the compressor body. A gas release channel provides communication between a gas phase portion of the water separating/recovering unit and the exterior of the water separating/recovering unit. A gas release on-off valve is disposed in the gas release channel. When the compressor body is not in operation, the discharge on-off valve and the water circulation on-off valve are closed and the gas release on-off valve is opened, allowing water to be recovered to the water separating/recovering unit. When there is no demand for compressed gas, it is possible to remove water from the water cooler, which otherwise may be damaged.
