8、 of13.8 6 0.3 MPa(2000 6 40 psi).Fluid temperature at thepump inlet is 66 6 3C for all water glycols,emulsions,andother water containing fluids and for petroleum and syntheticfluids of ISO Grade 46 or lighter.A temperature of 80 6 3Cis used for all other synthetic and petroleum fluids.4.2 The result
9、 obtained is the total mass loss from the camring and the twelve vanes during the test.Other reported valuesare initial flow rate and final flow rate.4.3 The total quantity of test oil required for a run is 26.5 L.5.Significance and Use5.1 This test method is an indicator of the wear character-istic
10、s of non-petroleum and petroleum hydraulic fluids operat-ing in a constant volume vane pump.Excessive wear in vanepumps could lead to malfunction of hydraulic systems incritical applications.6.Apparatus6.1 The basic system consists of the following(see Fig.1):6.1.1 AC Motor,1200-rpm,or other suitabl
