Simulation Study on Hydrodynamic Load-carrying Characteristics of Micro-texture Valve Plate Pair in Piston Pumps
摘要
Abstract
The support and friction characteristics of the valve plate pair in piston pumps are crucial for reliability and lifespan.Various micro-texture models are constructed,and the entire pump flow field is simulated using Fluent software to compare the dynamic pressure characteristics and support forces of different micro-textures.The study further investigated the effects of slanted rectangle texture angle and rotational speed on oil film performance.Results show that all micro-textures improve dynamic pressure and support force,with slanted rectangle textures outperforming others.The dynamic pressure characteristics increase with pump speed but initially increase and then decrease with largerslanted rectangle texture angles,peaking at0.1455 MPa.The minimum oil film support force occurres at 75°angle,while the maximum friction is at 15°.The larger angles have a greater impact on friction coefficient at speeds above 2000 r/min,whereas below 2000 r/min,smaller angles have more significant effect.关键词
