<p>This invention relates to a method for the protection of a volumetric liquid-injected compressor of the type comprising a compressor element (1) driven by a motor (2), a pressure conduit (3), a separator (4) for injection liquid erected in this pressure conduit (3), an injection conduit (6) for injecting the separated injection liquid into the compressor element (1), and a liquid-cooled cooler (7) in this injection conduit (6). The outlet temperature of the compressed gas is measured and, depending on at least this temperature and on a limit value, it is determined whether the motor (2) has to be stopped. Also, the environmental temperature in the outlet (5) for the cooling water of the radiator (9) is measured and the limit value is rendered dependent on this environmental temperature.</p> |
