Abstract A multi-functional experimental platform for pump and device model DN 500 mm(Technical and Research Center of Fluid Machinery Engineering,Jiangsu University)was introduced with its main technical specifications and system structure.The methods to improve precision were analyed,and the precision was tested by uncertainty theory.During this platform development,10 groups of performance data were got by repeated measuring a model pump with 500 specific speed at same state,then uncertainty of type A was obtained.From precision analysis of measuring instrument,uncertainty of type B was obtained.Combining type A with type B component,the uncertainty of this pump model is 0.25%,less than 0.40% of Water Industry Standard SL 140—2006.The analysis shows that main influence factors on the platform test precision are water-cycle system and measurement-control system.This experimental platform has adequate measurement accuracy and can meet the needs of various kinds of experiment.It has a great significance in improving the manufacturing level of the related pump industry and research lever on pump and device model.
