一、前言水轮发电机组需要进行轴线检查和调整,这在安装程序上称为盘车。根据刘家峡电站的安装经验,发电机可不必单独进行盘车,而在发电机转子与水轮机转轮联接后一次进行。按拖动方法不同,盘车一般可分机械盘车(如刘家峡的机组)和电动盘车(如青铜峡机组)两种。在盘车过程中,主要是预测主轴有关部位的摆度参数,使之达到规定要求,为机组运行时的摆度稳定性创造可靠条件。
I. Preface Hydrogenerator sets need to be checked and adjusted for the axis, which is called a crank car on the installation program. According to the installation experience of Liujiaxia Hydropower Station, the generator may not need to crank the car alone, but will be carried out once the generator rotor and the turbine runner are connected. According to the different dragging methods, the turning car can be divided into two kinds: the mechanical turning vehicle (such as Liujiaxia machine) and the electric turning vehicle (such as Qingtongxia machine). In the turning process, the main parameters of the spindle to predict the swing of the relevant parts of the spindle to meet the requirements of the stability of the unit for the operation to create a reliable condition.
