FIELD: physics; control. ^ SUBSTANCE: invention relates to devices for controlling vibration and protecting rotor 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 phase mark sensors 8 and axial shift sensors 9-11, temperature sensors 12, first 13 and second 14 analogue-to-digital converters, asynchronous interface 15, data bus 16, input interface 17, computer 18, the output 19 of which is the output of the protective shutoff signal of the assembly, matching elements 20-32, signal conditioner 33, signal processor 34, microcontroller 35, auxiliary asynchronous serial bus 36, auxiliary input interface 37, protection logic module 38, the output of which is the auxiliary output 39 of the alarm signal. Power buses 40 and 41 are connected to inputs of the secondary power module 42, outputs of which are connected to power inputs of the matching elements 20-32, and auxiliary outputs 43 are power buses of the data collecting and processing unit. Other versions of the device are also proposed. ^ EFFECT: more reliable operation. ^ 25 cl, 33 dwg |
