Hydraulic Test is to use hydraulic test equipment for hydraulic components and hydraulic systems for the testing and performance evaluation. So hydraulic experiment in the production of hydraulic components play an important role in the hydraulic components detection devices, Not only can the test be targeted at rated conditions, work for a specified time after the performance appraisal, but also to try to be the targets of life, the environment pressure and adapt to the changes in the ability to conduct an effective test. This integrated detection device designed mainly include : hydraulic components detection device hydraulic system design, Hydraulic Components detection device hydraulic system hydraulic components of the type design, hydraulic components of the structural design, hydraulic components of the pilot project and test methods, and several other aspects. This paper studies pump-motor-cylinder independent detection device, and research and analysis design a set of complete functions to detect pump-motor-cylinder power recovery of non-integrated detection device and the AUTO ACD painted on the chart, assembly drawings.
