城市防洪泵站振动测试技术探析

为对城市防洪泵站运行中异常、连续的振动进行测试，为泵站维修前后的振动提供对比数据，安装振动测试系统。分析泵站振动变送器的原理、选型，介绍测试系统的组成原理，阐述振动测试系统的安装及注意事项，以及测试系统的校准方法。振动测试系统投入运行几个月来采集的数据，对振动工况的判断、水泵和电机的运行性能，以及维修前后的振动情况对比提供支持，达到了预期目的。

Explore and Analysis of Vibration Measuring Technology in

In order to measure the unusual and continuous vibration in operation of pumping station of city flood control and to provide comparative data of vibration before and after the maintenance, for the pumps it installs the vibration measuring system. The article analyzes the principle and selection of pump vibration transmitter and introduces the composition principle of measuring system. And it expounds its installation, attention items and its certification method of the measuring system. The data collected in the past few months after the vibration measuring system has been put into operation, can supply the support for judging the vibration condition, the operation performance of the pump and motor and vibration comparison before and after repairing. It has achieved expected purpose.
