在旋转机械故障中,80％的机器故障是由三个基本原因引起的——不平衡,不对中和轴承不稳定,其中转子不平衡占21.2％。因此,解决动平衡问题是工程技术人员排除机械故障的首要任务之一。每台机组出厂都要在平衡机上进行低速动平衡和高速动平衡试验,然而由于平衡机的条件与机组现场条件有很大差别,而且来 In a rotating machine failure, 80% of machine faults are caused by three basic causes - unbalance, misalignment and bearing instability, with rotor imbalances accounting for 21.2%. Therefore, to solve the problem of balance is one of the most important tasks for engineers and technicians to eliminate mechanical failure. Each unit at the factory to be carried out in the balancing machine low-speed dynamic balancing and high-speed dynamic balance test, but because of the balancing machine conditions and the unit site conditions are very different, and to
