Abstract

The invention discloses a vertical rotor system with an active vibration suppression function and an active vibration suppression method thereof. The vertical rotor system is composed of a driven rotor main shaft, a bearing box with a spherical hinge support, a variable rigidity and damping electromagnetic bearing, a sensor, a measuring transmitter, a controller and a working section, wherein thedriven rotor main shaft is used for generating rotating mechanical energy to drive the working section to do work, the working section can be arranged at the top end or the bottom end of the driven rotor main shaft according to the working requirement of the rotor system, a bearing in the bearing box is used for supporting a rotor, the spherical hinge support is used for vibration reduction, and the sensor, the measuring transmitter, the controller and the variable rigidity and damping electromagnetic bearing forms an active vibration suppression system which is used for realizing active vibration suppression of the rotor subsystem. By detecting the vibration of the rotor, analyzing the vibration of the rotor to generate a control signal to adjust the rigidity and damping of the electromagnetic bearing, thereby outputting the corresponding damping force, and achieving active suppression of vibration of the vertical rotor system.

Description

technical field [0001] The invention relates to the technical field of active vibration control of a vertical rotor system, in particular to a vertical rotor system with an active vibration suppression function. Background technique [0002] Common vertical rotor systems include supergravity machines, centrifuges, circulating pumps, etc. They are widely used in chemical, electric power, energy and other fields, and occupy an important position in modern industrial production. Taking the high-gravity gas desulfurization process as an example, the unique flow behavior of multi-phase flow system under high-gravity conditions is used to strengthen the relative velocity and mutual contact between phases, so as to realize efficient mass transfer, heat transfer process and chemical reaction process. The way to obtain supergravity is mainly to form a centrifugal force field by rotating the whole or parts of the equipment, and the multiphase flow system involved mainly includes gas-s...

AI Technical Summary

Problems solved by technology

However, the dampers used in existing vertical rotor systems are often passive, and from the perspective of the actual form of force, the damper can only simply impose additional fixed damping on the rotor during the operation of the rotor, which makes it damper. Vibration range and functionality are quite limited
