本文对现行通风机行业标准中有关动平衡的某些规定进行了分析,指出:标准中规定的在动平衡机上评定和在工作状态下电机轴承处的振动来评定所达到的平衡精度是不合理的。因为它不能确切地知道残余不平衡量。建议应将平衡好的时轮在整机上测定其残余不平衡量,文中介绍了测定残余不平衡量的方法。
This paper analyzes some of the current regulations regarding dynamic balancing in the industry standard for ventilators and points out that it is unreasonable to rate the accuracy of the balance as assessed by the standard on dynamic balancing machines and by vibration at the motor bearings under working conditions of. Because it can not exactly know the residual unbalance. It is suggested that a well-balanced hour wheel should measure its residual unbalance on the whole machine, and the method of measuring the residual unbalance is introduced in this paper.
