【摘要】：水轮发电机组轴线的检查与调整,一直以来是水轮发电机组安装或者检修中很重要的一项工作,轴线调整的好坏对机组运行的稳定性和导轴承的正常工作有直接影响。传统的轴线摆度测量和数据分析处理都是采用人工方式,准确性和可靠度都不高,影响了轴线调整的质量。云峰发电厂盘车数据采集分析处理系统的开发利用了当今先进的传感器技术、电子技术、通信技术、计算机技术等。相对于传统盘车方法,从轴线摆度的测量、主轴角位移的测量和数据的分析处理方面都做了大的改进。在数据测量方面,通过对主要硬件设备的选型及电路设计,完成了摆度测量装置及角度测量装置的开发。其中,摆度测量选用了高精度的电涡流位移传感器,提高了测量的精度;角度测量选用了高精度的角位移传感器(旋转编码器),可以确定主轴旋转的任意方位,突破了传统盘车八点的限制;在数据分析处理方面,基于Visual Basic 6.0集成开发环境开发了一套盘车数据采集分析处理软件,该软件内集成了两种盘车方案。本盘车数据采集分析处理系统可以完成盘车数据的采集、数据处理工作,并给出盘车结果的综合处理意见,方便工程技术人员参考。本课题开发的云峰发电厂盘车数据采集分析处理系统在云峰发电厂、白山发电厂检修盘车时做过多次试验,与采用传统盘车方法相比,克服了测量仪器精度不高、人工读表及手工数据处理等方面可能带来的误差,加快了盘车工作速度,得到的处理结果更加科学,具有更高的可信度。现场试验表明本系统具有很好的实用性,值得推广应用。
[Abstract]:The inspection and adjustment of the axis of a hydrogenerator unit has always been a very important task in the installation or maintenance of a hydrogenerator unit. The adjustment of the axis line has a direct impact on the stability of the unit operation and the normal work of the guide bearing. The traditional axis pendulum measurement and data analysis are manual, the accuracy and reliability are not high, which affects the quality of axis adjustment. The development of data acquisition, analysis and processing system in Yunfeng Power Plant has made use of the advanced sensor technology, electronic technology, communication technology, computer technology and so on. Compared with the traditional method, great improvements have been made in the measurement of axis pendulum, the measurement of spindle angular displacement and the analysis and processing of data. In the aspect of data measurement, through the selection of main hardware equipment and circuit design, the development of pendulum measuring device and angle measuring device is completed. Among them, the high precision eddy current displacement sensor is used in the pendulum measurement, and the angle measurement adopts the high precision angle displacement sensor (rotary encoder), which can determine any azimuth of the spindle rotation. In the aspect of data analysis and processing, a set of data acquisition and analysis processing software is developed based on Visual basic 6.0 integrated development environment. The data collection and analysis system can complete the data collection and data processing, and give the comprehensive processing advice of the results, which is convenient for engineers and technicians to refer to. The data collection, analysis and processing system of Yunfeng Power Plant has been tested many times in Yunfeng Power Plant and Baishan Power Plant. Compared with the traditional method, the precision of measuring instrument is not high. The error caused by manual reading table and manual data processing accelerates the working speed of the truck, and the results are more scientific and more reliable. The field test shows that the system has good practicability and is worth popularizing.
