Design on Inner Loading Hydraulic Pressure Test System of Large diameter Double Telescopic Leg
Abstract：In order to solve the issues of the routine workshop test and the delivery test for the 500 mm diameter hydraulic leg, a horizontal inner loading testing rig of the large diameter double telescopic hydraulic leg was introduced. The pressurized loading system of the testing rig could have a pressure higher than the inner loading testing pressure from the emulsion pump and had completed the pressure resistance performances, tensile pressure performances and other test of the cylinder leg. Based on the hydraulic components applied to the testing system, a head and tail connection of a pair of the hydraulic cylinder was applied to establish a Simhydraulics model and to complete the load efficient curve drawing of the simulated and actual measured support performances. The Visual C# prepared data acquisition pro- gram was applied, according to the test data of the test procedure automatic acquisition test system and the of the data documents of the automatic output test reporter, the study results showed that the testing system could meet the inspection requirements of the large diameter leg and could highly improve the production efficiency of the legs.
