8、ummary of Test Method4.1 Hydraulic fluid in the amount of 190 6 4 L (50 6 1 gal)is circulated through a rotary vane pump system for 50 h at apump speed of 2400 6 20 r/min and a pump outlet pressure of20.7 6 0.2 MPa (3000 6 20 psig). Fluid temperature at thepump inlet is 95 6 3C (203 6 5F).An ISO Gra
9、de 32 or 10Wviscosity is required.4.2 The cam ring and all ten vanes should be individuallyweighed before and after the test. The weight loss of the camring should be reported with the combined weight loss of allten vanes. The intra-vanes (inserts) are not part of the requiredweight loss measurement
10、s and should be separately measuredif desired. Other reported values are fluid cleanliness beforeand after the test, initial flow rate, and final flow rate.4.3 Prior to installing the hydraulic test fluid into the rig, astand flush is required to remove any contaminants. A mini-mum quantity of 190 6
11、 4 L (50 6 1 gal) of fluid (see Note 1)made of the same chemical formulation as the test fluid, isrequired for the stand flush. Therefore the total quantity of oilrequired for the test is 380 L (100 gal).5. Significance and Use5.1 This test method is an indicator of the wear character-istics of petr
