TEST RIG FOR HYDRAULIC FLUID (A3987) - NEOMETRIX DEFENCE
- 3. The test rig is used to test the anti-wear properties and the aging behaviour of hydraulic fluids under defined and reproducible conditions. For this purpose, a vane pump Vickers 35VQ25A-11*20 for ASTM D6973-2014 and a Bent Axis type axial piston pump A2F10 for JCMAS P 045 are used as test objects. The subsequent investigation of the wear inserts and oil condition then allows conclusions about the performance of the tested fluids, especially their ability to avoid wear and resist oxidation. The modern and ergonomically designed test rig meets all the specifications of the European Machinery Directive 2006/42/EG to a high standard or equivalent Indian Standard. The test rig is used to determine the wear characteristics and oxidation/ aging of non-petroleum and petroleum hydraulic fluids. For this purpose, a rotary vane pump generates a test pressure under specific boundary conditions. The result obtained is the total mass loss from the cam ring and the ten vanes (ASTM D6973-2014) after the test. For indicating oxidation stability or aging behaviour of hydraulic fluids this test bench, uses a bent axis pump A2FO10 and a pressure relief valve DBDS 10 K1X/400V as load at high temperatures. The test takes place under the influence of air and a copper catalyst. This procedure allows for an accelerated aging rate using a real hydraulic component. The test rig parameters meet the specifications according to ASTM D6973-2014 and JCMAS P 045. Additionally, it is capable of carrying out the evaluation of hydraulic fluid for frictional characteristics and energy efficiency performance under indigenously developed and industrially simulated test methods by varying load, speed, temperature, pressure, flow rate etc.
