METHOD FOR REDUCING VIBRATIONS AND A DEVICE FOR ITS IMPLEMENTATION - VIBROSHUNT -VIBRATIONER Russian patent published in 2023 - IPC F17D1/00 F17D1/20 F16L55/02 

FIELD: vibration dampers.

SUBSTANCE: effect is achieved by transferring the vibration energy from one part 2 of the pipeline 1 to the vibration shunt-vibration damper 3, made in the form of a cylindrical shell 6, connecting the elements 7 and 8 of the vibration shunt-vibration damper 3, adjacent to the wall of the protected pipeline 1, and placed with the formation of a gap between the vibration shunt-vibration damper 3 and the local area 4 of the pipeline 1 and connected to the pipeline 1 by welding with continuous weld penetration, while in the body of the cylindrical shell 6 screw grooves 9 are made with the axis of the helical surface coinciding with the longitudinal axis of the vibration shunt-vibration damper 3.

EFFECT: Reducing the vibration level of pipeline 1 connected to the casing of a compressor, pump or other technological machine.
