- Abstract
The dynamic balance of cross-flow fan was primarily implemented by manual balance sheetmetal, and there are some shortcomings that low precision and easily fall off. In this paper, firstly, the mechanism of dynamic balance of cross-flow fan was elaborated. Then, the collection of unbalance is achieved by four pressure sensors, and the equivalent unbalances of end faces was obtained by the mechanisms of two end-face equivalent balance. And then, the NC drilling method was brought in cross-flow fan, and one or more holes drilling model were built, respectively. After that, the automatic dynamic balance equipment of cross-flow fan was developed by the PLC control system. Last, a set of experiment was came true on the independent equipment, and the result of experiment showed that the decrement rate of unbalance can reach 90%.
