Abstract

The Vickers V1044C Vane Pump Test has been widely applied to estimate the anti-wearp roperties of hydraulic fluids such as mineral oils and various fire-resistan ftluids. This paper studies the applicability of these test methods regarding high-water content fluids (HWCF). A s a result of this work, it wasr evealedth at the test pressuref or high-waterc ontent fluidso f the present state of the art should be low, namely 10-20 bar. Therefore, the special feature of this test, in which it simulates, though not satisfactorily the actual function of fluid powere lements, is thus lost for usual high-water content fluids. This test was able to show, however, the effects of anti-wear additives. Therefore, the test procedure itself maybe used to estimate the effect as an anti-wear agent when a high-water content fluids is finally developed.
