目前,我国水泵试验测试技术大部分仍采用U型水银差压计等人工目读观察办法,因此测定一个模型泵的性能工作量相当可观,每次试验所测数据,用人工计算费时太多,这样势必拉长研制周期。而一些技术先进的国家已经采用电子技术。为提高测试精度和工作效率,适应水力机械的各类试验研究的要 At present, most of the pump test technology in our country still uses the U-shaped mercury differential pressure manometer to read the observation method, so the performance of a model pump is very considerable. The data measured in each test is too much time and labor, This is bound to lengthen the development cycle. Some advanced countries have adopted electronic technology. To improve the test accuracy and work efficiency, to adapt to various types of hydraulic machinery and experimental research
