随着我国水电事业的发展,水轮发电机组容量越来越大,机械设备的结构变得越来越复杂,并且经常运行于高速、重载以及恶劣环境等条件下。由于各种因素的干扰和影响,会导致机械设备发生故障,轻则降低生产质量或导致停产,重则会造成严重的甚至是灾难性的事故。水轮发电机组的安全生产成为至关重要,迫切需要解决的问题。水力机械振动的诸原因中,机械振动是占第一位的。由于机组轴线不正,轴承间隙不
With the development of hydropower in our country, the capacity of hydro-generating units is getting larger and larger. The structure of the machinery and equipment is becoming more and more complex, and often operates under conditions of high speed, heavy load and harsh environment. Due to the interference and influence of various factors, it will lead to mechanical equipment failure, ranging from reducing the quality of production or lead to the shutdown, will result in serious or even catastrophic accidents. Hydro-generator safety production has become crucial, urgent problems to be solved. Among the reasons for the vibration of hydraulic machinery, mechanical vibration is the top one. As the unit axis is not correct, bearing clearance is not
