The flow analysis of a slipper bearing in a swash plate axial piston pump involves studying the hydrodynamics and behavior of the lubricant within the bearing. Plain bearings are important components that support the swash plate and facilitate the smooth movement of the pistons. Following are the key aspects of flow analysis in plain bearings: 1. Lubricant supply: Flow analysis considers how lubricant (usually hydraulic oil) is supplied to the plain bearing. It checks the oil flow path from the pump's reservoir or an external source, through the pump's inlet port, into the shoe bearing assembly. 2. The formation of lubricating oil film: focus on the analysis of the formation and maintenance of lubricating oil film between the shoe bearing and the swash plate. The thickness and uniformity of the film directly affect the performance, friction and wear characteristics of the bearing. 3. Pressure distribution: Understanding the pressure distribution within a slipper bearing is critical to ensuring proper lubrication. Flow analysis examines how oil pressure changes across bearing surfaces, taking into account factors such as bearing geometry, oil viscosity, and operating conditions. 4. Hydrodynamic lubrication: Flow analysis studies the hydrodynamic lubrication mechanisms that occur in plain bearings. It examines how the relative motion between the shoe and swash plate creates a pressure gradient that causes lubricant to flow and create a hydrodynamic wedge that supports the load. 90L250-KP-5-NN-80-T-3-F1-J-03-NNN-35-35-24 90L250KP5NN80T3F1J03NNN353524 90-L-250-KP-5-NN-80-T-3-F1-J-03-NNN-35-35-24 90L250KP5NN80T3F1J03NNN353524 90-L-250-KP-5-NN-80-T-3-F1-K-03-NNN-42-42-24 90L250KP5NN80T3F1K03NNN424224 90L250-KP-5-NN-80-T-4-C8-J-04-NNN-26-26-24 90L250KP5NN80T4C8J04NNN262624 90-L-250-KP-5-NN-80-T-4-C8-J-04-NNN-26-26-24 90L250KP5NN80T4C8J04NNN262624 90L250-KP-5-NN-80-T-4-C8-K-03-NNN-26-26-28 90L250KP5NN80T4C8K03NNN262628 90-L-250-KP-5-NN-80-T-4-C8-K-03-NNN-26-26-28 90L250KP5NN80T4C8K03NNN262628 90L250-KP-5-NN-80-T-4-C8-K-03-NNN-32-32-28 90L250KP5NN80T4C8K03NNN323228 90-L-250-KP-5-NN-80-T-4-C8-K-03-NNN-32-32-28 90L250KP5NN80T4C8K03NNN323228 90L250-KP-5-NN-80-T-4-F1-J-03-NNN-35-14-24 90L250KP5NN80T4F1J03NNN351424 90-L-250-KP-5-NN-80-T-4-F1-J-03-NNN-35-14-24 90L250KP5NN80T4F1J03NNN351424 90L250-KP-5-NN-80-T-4-F1-J-03-NNN-35-35-24 90L250KP5NN80T4F1J03NNN353524 90-L-250-KP-5-NN-80-T-4-F1-J-03-NNN-35-35-24 90L250KP5NN80T4F1J03NNN353524 90L250-KP-5-NN-80-T-4-F1-K-03-NNN-29-29-24 90L250KP5NN80T4F1K03NNN292924 90-L-250-KP-5-NN-80-T-4-F1-K-03-NNN-29-29-24 90L250KP5NN80T4F1K03NNN292924 90L250-KP-5-NN-80-T-4-F1-K-03-NNN-42-42-24 90L250KP5NN80T4F1K03NNN424224 90-L-250-KP-5-NN-80-T-4-F1-K-03-NNN-42-42-24 90L250KP5NN80T4F1K03NNN424224 90-L-250-KP-5-NN-80-T-4-F1-K-05-NNN-32-32-24 90L250KP5NN80T4F1K05NNN323224 90L250-KP-5-NN-80-T-4-F1-K-05-NNN-35-35-24 90L250KP5NN80T4F1K05NNN353524 90-L-250-KP-5-NN-80-T-4-F1-K-05-NNN-35-35-24 90L250KP5NN80T4F1K05NNN353524 5.

Oil film thickness: The focus of the analysis is to determine the oil film thickness between the shoe bearing and the swash plate. This is critical to preventing metal-to-metal contact, reducing friction and ensuring proper load support. 11. Velocity and shear stress distribution: Flow analysis examines the velocity and shear stress distribution within the lubricating film. Knowing these parameters helps assess the effectiveness of lubrication and identify areas of high shear that may lead to increased or degraded wear. 12. Bearing clearance optimization: The analysis aims to optimize the bearing clearance that affects the fluid flow characteristics. Proper clearance is required to promote hydrodynamic lubricant film formation, while excessive clearance will result in reduced load support and increased leakage. 13. Effect of swash plate angle: The flow analysis takes into account the swash plate angle as it affects the fluid flow pattern within the plain bearing. Changing the angle of the swash plate changes the direction and velocity of oil flow, which affects lubrication and bearing performance. 14. Bearing Design Optimization: Flow analysis helps to optimize the design of slipper bearings to enhance their lubricating characteristics. Factors such as bearing geometry, surface finish, and the presence of features such as oil grooves or microtextures can be evaluated to improve flow patterns and lubrication effectiveness. 90L250-MA-5-EG-80-S-4-C8-K-C3-NNN-38-38-24 90L250MA5EG80S4C8KC3NNN383824 90-L-250-MA-5-EG-80-S-4-C8-K-C3-NNN-38-38-24 90L250MA5EG80S4C8KC3NNN383824 90L250-MA-5-NN-80-S-3-F1-K-C4-NNN-32-32-24 90L250MA5NN80S3F1KC4NNN323224 90L250-MA-5-NN-80-S-4-F1-J-C5-NNN-42-42-24 90L250MA5NN80S4F1JC5NNN424224 90-L-250-MA-5-NN-80-S-4-F1-J-C5-NNN-42-42-24 90L250MA5NN80S4F1JC5NNN424224 90L250-MA-5-NN-80-T-3-C8-K-C5-NNN-23-23-24 90L250MA5NN80T3C8KC5NNN232324 90-L-250-MA-5-NN-80-T-3-C8-K-C5-NNN-23-23-24 90L250MA5NN80T3C8KC5NNN232324 90L250-MA-5-NN-80-T-3-C8-K-C5-NNN-32-32-24 90L250MA5NN80T3C8KC5NNN323224 90-L-250-MA-5-NN-80-T-3-C8-K-C5-NNN-32-32-24 90L250MA5NN80T3C8KC5NNN323224 90-R-055-DC-1-AB-60-P-4-S1-C-GB-GBA-42-42-24 90R055DC1AB60P4S1CGBGBA424224 90-R-055-DC-1-AB-80-D-4-S1-L-GB-GBA-38-38-20 90R055DC1AB80D4S1LGBGBA383820 90-R-055-DC-1-AB-80-D-4-S1-L-GB-GBA-38-38-20-F001 90R055DC1AB80D4S1LGBGBA383820F001 90-R-055-DC-1-AB-80-D-4-S1-L-GB-GBA-38-38-24-F001 90R055DC1AB80D4S1LGBGBA383824F001 90-R-055-DC-1-BC-60-P-4-S1-C-GB-GBA-35-35-24 90R055DC1BC60P4S1CGBGBA353524 90-R-055-DC-1-CD-60-S-3-S1-B-GF-GBA-26-26-24 90R055DC1CD60S3S1BGFGBA262624 90-R-055-DC-1-CD-80-L-4-S1-C-GB-GBA-29-29-24 90R055DC1CD80L4S1CGBGBA292924 90-R-055-DC-1-NN-60-D-4-S1-L-GB-GBA-35-35-20 90R055DC1NN60D4S1LGBGBA353520 90-R-055-DC-1-NN-60-D-4-S1-L-GB-GBA-35-35-24 90R055DC1NN60D4S1LGBGBA353524 90-R-055-DC-1-NN-60-P-3-C6-D-GB-GBA-26-26-20 90R055DC1NN60P3C6DGBGBA262620 90-R-055-DC-1-NN-60-S-3-S1-D-GB-GBA-42-42-24 90R055DC1NN60S3S1DGBGBA424224 15. Cavitation and Aeration: Flow analysis investigates the possibility of cavitation or aeration in plain bearings. Cavitation occurs when the partial pressure is lower than the vapor pressure of the lubricant, resulting in the formation of air bubbles. Aeration involves introducing air or gas into the lubricant. Both cavitation and aeration can adversely affect lubrication and cause bearing surface damage. 16. Verification and performance evaluation: compare the results of flow analysis with experimental data or theoretical models to verify the accuracy of the simulation. Performance indicators such as bearing friction, power loss and temperature rise can be evaluated to assess the effectiveness of the lubrication system. A comprehensive flow analysis of the plain bearings of a swash plate axial piston pump allows engineers to gain insight into lubrication characteristics and make informed design decisions. This analysis helps to optimize bearing performance, reduce frictional losses, improve energy efficiency and improve the overall reliability of the pump.
