摘要：The use of liquid auto-balancers to compensate theoperational changes in the imbalance of rotary systemswithout stopping them is of interest because of the relativestructural simplicity of these devices, which are passive direct-acting regulators that do not require power supply andcontrol systems to move correction masses. The experienceof the study of passive auto-balancing devices (SBD) indicates that the existing theory (statements) of passive automatic balancing of the fluid is idealized and inaccurately describes the processes that occur with the working bodiesduring their operation. In particular, the lack of studies onthe effect of liquid viscosity on the efficiency of self-balancing and the reasonableness of the selection of liquid duringthe development of fluid SBD demanded to analyse the operation of liquid SBD in the real system, taking into accountthe influence of liquid properties on the efficiency of thevertical rotor balancing process. It is shown that the efficiency of balancing increases with the approach of the angular velocity to the critical one and with the increase of theexternal resistance. The massive forces of the working fluidhave less effect on the balancing efficiency than the viscosity for liquid SBDs.
