Review for liquid-typed online auto-balancing device in rotor-bearings system
: Auto-balancing device can adjust the unbalance state of rotor-bearings system, increase work efficiency and extend the service life of machines. According to the analysis of domestic and foreign existing liquid-typed automatic balancing device, there are four types: liquid injection, liquid release, continuously-dripping liquid injection, and liquid transfer. Because the first three types need the processes of liquid injection and release, they have several unavoidable faults. For the liquid transfer type, it avoids these two processes and is much better. For the liquid injection type, its structure is simple and there is no movable units in the rotating parts. The research direction of liquid typed balancing devices is to invent new structure of the liquid transfer type with keeping the advantages of liquid injection type.

Because the first three types need the processes of liquid injection and release, they have several unavoidable faults. For the liquid transfer type, it avoids these two processes and is much better. For the liquid injection type, its structure is simple and there is no movable units in the rotating parts. The research direction of liquid typed balancing devices is to invent new structure of the liquid transfer type with keeping the advantages of liquid injection type.
