FIELD: machine building.
SUBSTANCE: present invention relates to a method of controlling the output temperature of a compressor or vacuum pump (1) with oil injection, comprising a compressing or vacuumizing element (4) having inlet (5) for gas, outlet (6) of the element and an inlet oil pipeline (12); said method includes steps of measuring output temperature (Tout) at element output (6); adjusting position of control valve (15) for controlling oil flow flowing through cooling device (13) connected to said inlet oil pipeline (12); wherein control valve positioning stage (15) includes application of fuzzy logic algorithm to measured output temperature (Tout); additionally, the method includes the stage of fan (21) rotation speed control, which is cooling the oil flowing through cooling device (13), by using the fuzzy logic algorithm and, further, based on control valve (15) position.
EFFECT: invention discloses control method of compressor or vacuum pump with oil injection and compressor or vacuum pump with oil injection for this method implementation.
