A method for controlling the outlet temperature of an oil-injected compressor or a vacuum pump, and an oil-injected compressor or vacuum pump implementing this method

摘要

The present invention relates to a system for controlling the outlet temperature of an oil-injected compressor or vacuum pump (1) comprising a gas inlet (5), an element outlet (6) and a compressor or vacuum element The method comprising: measuring an outlet temperature (T _out ) at the element outlet (6); - controlling the position of the regulating valve (15) to regulate the flow of oil flowing through the cooling unit (13) connected to the oil inlet (12), wherein the position of the regulating valve The step of controlling entails applying a fuzzy logic algorithm to the measured outlet temperature T _out ; The method further includes controlling the speed of the fan (21) that cools the oil flowing through the cooling unit (13) by applying a fuzzy logic algorithm and also based on the position of the control valve (15).
