VIBRATION CONTROL DEVICE (VERSIONS) Russian patent published in 2009 - IPC G01M15/00 

FIELD: physics; control.

SUBSTANCE: invention relates to devices for vibration control and protection of rotary assemblies such as turbines. The vibration control device has a data collecting and processing unit 1, sensors 2-6, fitted on bearing assemblies 7, as well as sensors of the phase mark 8 and axial shift 9-11 of the rotor 12, first 13 and second 14 analogue-to-digital converters, asynchronous interface 16, data bus 17, input interface 18, computer 19, output 20 of which is the signal output for shutoff protection of the assembly, matching elements 21-32, signal conditioner 33, signal processor 34, microcontroller 35, auxiliary asynchronous serial bus 36, auxiliary input interface 37, protection logic module 38, output of which is auxiliary output 39 for the alarm signal. Power buses 40 and 41 are connected to the input of a secondary power module 42, outputs of which are connected to power inputs of matching elements 21-32, and auxiliary outputs 43 are power buses for the data collection and processing unit 1.

EFFECT: more reliable functioning.
