Hydraulic system failure with elusive, transformation-induced and inducing factor multiplicity, so in the fault diagnosis and rule out the possibility, not only the need for skilled personnel, but also have a well-developed testing equipment, most of the test equipments that used for detecting the performance parameters of hydraulic components are a single hydraulic test bed. And generally to hydraulic parts manufacturers and research institutes dedicated. From the perspective of using, once the hydraulic system failure, are often required to detect a wide range of hydraulic components of the technical indicators to identify the root causes of fault location and to achieve the purpose of timely repairs. In this paper we explain the design of one kind of hydraulic test bench, working principle and the main technical indicators. It combinated the performance of hydraulic valves and hydraulic cylinders dedicated test-bed, to become multiple use, the test bench with characteristics of test reliable, easy to manufacture, easy maintenance, low cost and so on.Key words: hydraulic test stand; tank; hydraulic valve; hydraulic cylinder; forcing press
