The Research on the Hydraulic Test-Bed of Cylinder

In this paper, the test methods of the Hydraulic Test-bed of Cylinder are researched, such as hydraulic cylinder stroke test, buffer test, high temperature test, internal leakage rate test ultrahigh pressure test. The measurement and control system is made up by industrial control computer, programmable logical controller, data acquisition card, analog control card and high precision sensors. The states and parameters of the test-bed are supervised and detected by the measurement and control system in real time. Different type hydraulic pumps, proportional pressure regulation and other methods are used by hydraulic control system. High efficiency, energy saving, high precision and intelligent control test are achieved by the hydraulic control system. Test items are automatic tested and measuring precision is improved by the test-bed.
