英文摘要：

The hydraulic automatic balancing technology is presented to solve dynamic imbalance caused by the scale in the running of the fan rotor. The finite element dynamic model of a certain fan was built with rotor dynamics software. According to three possible installation planes of balancing head, the balancing effect of balancing head which was virtually installed on these three installation planes was calculated respectively with rotor dynamics software, and the optimization installation plane of balancing head was found. Moreover, a fan simulation test rig was designed, and the hydraulic automatic balancing experiment was done. Laboratory experiments show that hydraulic automatic balancing head installed on the optimization plane can realize on-line automatic balancing of rotor without stopping the operation, It provides theoretical and experimental basis for the application of hydraulic automatic balancing technology to the fan.
