Centrifugal separator device for filtering blow-by gas in crank case ventilation device in motor car, has plate separator for filtering fluid, and monitoring and diagnostic apparatus for monitoring or diagnosing operability of separator

摘要

The device has a disk or plate separator (10a) for filtering fluid by centrifugal energy. A monitoring and diagnostic apparatus (11a) monitors or diagnoses operability of the disk or plate separator. The diagnostic apparatus comprises an evaluation unit (12a) that evaluates a drive parameter of the disk or plate separator. The diagnostic apparatus comprises a rotation speed sensor (13a) that detects the drive parameter. A fluid drive (14a) drives the disk or plate separator by the fluid and comprises a nozzle (15a). An electric drive electrically drives the disk or plate separator. The drive parameter is selected from a group consisting of rotation speed, a rotational torque, electrical power consumption and/or an electrical power input.
