VIRTUAL SENSOR FOR WATER CONTENT IN OIL CIRCUIT

A method for monitoring an oil-injected screw compressor configured to compress aspirated air by returning oil from an oil separator vessel (11) to a compression chamber (12) of a compressor block (30), for condensate formation in the oil circuit due to a too low compression discharge temperature (V...

Beschreibung
Zusammenfassung:	A method for monitoring an oil-injected screw compressor configured to compress aspirated air by returning oil from an oil separator vessel (11) to a compression chamber (12) of a compressor block (30), for condensate formation in the oil circuit due to a too low compression discharge temperature (VET), determines a water inlet mass flow {acute over (m)}ein(t) and a water outlet mass flow {acute over (m)}aus (t) for a point in time t and determines generated condensate flow Δ{acute over (m)}w (t)={acute over (m)}ein(t)−{acute over (m)}aus (t) on the basis of difference formation.
