水轮机差压法及超声波法效率试验软件的设计及实现

Turbine Index Method and Design and Implementation of Ultrasonic Method Efficiency Test Software

水轮机效率试验是评价水轮机性能的重要指标。目前,国内效率试验的做法通常是要根据试验使用的方法(如蜗壳差压法和超声波法等),选择特定的数据采集硬件结合自行开发的软件进行。文中设计开发了一套可采用蜗壳差压法或超声波法进行水轮机效率试验的软件测试系统,数据采集的硬件选用USB-4711数据采集卡,软件采用Delphi语言。文中介绍了该系统的功能特点以及设计思路。

Turbine efficiency test is one of the most important evaluation guidelines for turbines. Presently, the usual test method of turbine efficiency test at home is based on the specific test method （for example, the index method or the ultrasnoic method）, and a specified data acquisition hardware is chosen to accomplish the test with the self-developed software. This paper introduces a software system written in Delphi program language combined with USB-4711 data acquisition hardware for the implementation of the turbine efficiency test by the index method or the ultrasnoic method.
