Method for controlling an oil injected compressor installation and oil injected compressor installation

Abstract

A method for controlling an oil-injected compressor device (1) includes an oil-injected compressor element (2) having an inlet (3a) and an outlet (3b), wherein an air filter (4) is provided at the inlet (3a) and an oil separator (6) is provided at the outlet (3b), wherein the oil separator (6) includes an inlet (7), an outlet (8) and an exhaust outlet (9) having an exhaust device (11) connected to a location (P1, P2) between the air filter (4) and the inlet (3a), characterized in that: the method includes the step of discharging gas from the oil separator (6) in at least two stages, the at least two stages including at least a burst stage and a slow stage, wherein the gas is discharged at a higher pressure and flow rate in the burst stage compared to the slow stage, and wherein the burst stage has a shorter duration than the slow stage. Method for controlling an oil injected compressor installation (1) comprising an oil injected compressor element (2) with an inlet (3a) and an outlet (3b), whereby on the inlet (3a) an air filter (4) and on the outlet (3b) an oil separation vessel (6) is provided, whereby the oil separation vessel (6) comprises an inlet (7), an outlet (8) and a blow-off outlet (9) that is provided with means (11) to blow off gas, whereby the means (11) are connected to a location (P1, P2) between the air filter (4) and the inlet (3a), characterized in that the method comprises the step of blowing off gas from the oil separation vessel (6) in at least two stages, comprising at least a burst stage and a slow stage, whereby in the burst stage gas is blown off at a higher pressure and flow rate than in the slow stage, and whereby the burst stage has a shorter duration than the slow stage.
