全球范围而言，水泵效率和性能的热力学测试方法大约于十多年前在工业领域开始得到大量应用，但目前在泵站测试中使用还不是很广泛。由于缺少直接的工业应用标准去保证热力学法测试结果的准确可靠，且多数泵站自身又缺乏足够经验来开展独立研究测试，所以迫切需要一些通用性的指导原则来推动相关领域的进展。通过对多城市多泵站的水泵效率测试和研究，本项目完成了41个泵站的152个城市供水水泵的性能测试。其中57个水泵同时使用了热力学法和传统方法。通过大量的现场测试，并与采用电磁流量计、超声波流量计等传统测试方法的对比，积累了许多关于热力学法和传统方法在水泵性能测试中的经验和技巧；测试研究成果进一步明确了热力学法的适用条件和范围，通过对实测中遇到的各种情况的处理和总结，提出了热力学方法的通用性指导应用原则。

Globally, the pump efficiency and performance tests by thermodynamic method began to be widely used in industrial fields a decade ago. However, this method is still not a general one in municipal pump stations of China. At present, there is no dedicated testing standard to ensure the test progress with reliable quality control, and many pump stations lack experience to carry out independent tests. So it’s necessary to put forth some general guidelines to help and promote the development of the related fields in China. Through the pump efficiency assessment and research in multi-cities and multi-stations, this study involved 152 testing in 41 pump stations. Among them, 57 pumps are tested by thermodynamic method and conventional method simultaneously. Through analyzing the situ testing data, and comparing the thermodynamic method with conventional methods taking magnetic and ultrasonic flow meter, plenty of precious experiences on both methods have been obtained. Moreover, by addressing and summarizing the variant issues in the testing progresses, the general guidelines in pumping test by thermodynamic have been put forth by HydraTek. Test results further clear the applicable conditions and scope of the thermodynamic method.
