The oil film pressure characteristics of an axial piston pump play a critical role in its operation and performance. Here are some key points about oil film pressure characteristics: 1. Hydrodynamic lubrication: Axial piston pumps rely on hydrodynamic lubrication to maintain a thin oil film between moving parts such as pistons and cylinders. This oil film prevents metal-to-metal contact and reduces friction, wear and heat. 2. Oil film thickness: The oil film thickness is a key parameter that determines the pressure characteristics of the oil film. It represents the separation between sliding surfaces and affects the load-carrying capacity and efficiency of the pump. Proper oil film thickness is critical to ensure effective lubrication and minimize frictional losses. 3. Pressure distribution: The oil film pressure distribution in the axial piston pump is uneven. It varies in different areas due to the interaction between the rotating piston and the stationary cylinder block. Pressure distribution affects the balance of forces and moments acting on the piston and contributes to the overall performance of the pump. 4. Peak pressure area: The oil film pressure is usually highest in the inlet and outlet areas of the cylinder block. These areas experience higher contact pressures and generate peak oil film pressures. Proper design considerations, such as optimizing the shape and surface finish of the piston and cylinder block, help ensure adequate oil film pressure in these critical areas. 90-R-180-HF-1-NN-80-S-M-F1-J-00-FAC-35-35-24 90R180HF1NN80SMF1J00FAC353524 90-R-180-HF-1-NN-80-S-M-F1-J-00-NNN-35-35-24 90R180HF1NN80SMF1J00NNN353524 90R180-HF-1-NN-80-S-M-F1-J-03-FAC-14-35-24 90R180HF1NN80SMF1J03FAC143524 90-R-180-HF-1-NN-80-S-M-F1-J-03-FAC-14-35-24 90R180HF1NN80SMF1J03FAC143524 90-R-180-HF-1-NN-80-T-C-C8-J-03-NNN-42-42-24 90R180HF1NN80TCC8J03NNN424224 90R180-HF-1-NN-80-T-C-F1-H-05-FAC-35-35-24 90R180HF1NN80TCF1H05FAC353524 90-R-180-HF-1-NN-80-T-C-F1-H-05-FAC-35-35-24 90R180HF1NN80TCF1H05FAC353524 90R180-HF-1-NN-80-T-M-F1-H-03-NNN-40-40-24 90R180HF1NN80TMF1H03NNN404024 90R180-HF-1-NN-80-T-M-F1-J-00-NNN-42-42-24 90R180HF1NN80TMF1J00NNN424224 90-R-180-HF-1-NN-80-T-M-F1-J-00-NNN-42-42-24 90R180HF1NN80TMF1J00NNN424224 90R180-HF-1-NN-80-T-M-F1-J-03-NNN-42-42-24 90R180HF1NN80TMF1J03NNN424224 90-R-180-HF-1-NN-80-T-M-F1-J-03-NNN-42-42-24 90R180HF1NN80TMF1J03NNN424224 90R180-HF-2-CD-80-T-C-C8-J-03-NNN-40-40-24 90R180HF2CD80TCC8J03NNN404024 90-R-180-HF-2-CD-80-T-C-C8-J-03-NNN-40-40-24 90R180HF2CD80TCC8J03NNN404024 90R180-HF-5-AB-80-S-C-C8-H-03-NNN-42-42-28 90R180HF5AB80SCC8H03NNN424228 90-R-180-HF-5-AB-80-S-C-C8-H-03-NNN-42-42-28 90R180HF5AB80SCC8H03NNN424228 90R180-HF-5-AB-80-S-M-C8-H-03-FAC-32-32-24 90R180HF5AB80SMC8H03FAC323224 90-R-180-HF-5-AB-80-S-M-C8-H-03-FAC-32-32-24 90R180HF5AB80SMC8H03FAC323224 90R180-HF-5-AB-80-S-M-C8-H-03-NNN-35-35-24 90R180HF5AB80SMC8H03NNN353524 90-R-180-HF-5-AB-80-S-M-C8-H-03-NNN-35-35-24 90R180HF5AB80SMC8H03NNN353524 5. Oil film rupture and cavitation: Insufficient oil film pressure or excessive load will cause axial piston pump oil film rupture or cavitation. Oil film rupture occurs when the oil film thickness becomes too thin, resulting in direct contact between the sliding surfaces. On the other hand, when the oil film pressure is lower than the vapor pressure of the oil, cavitation occurs, forming bubbles that burst under high pressure conditions, causing corrosion and damage. 6. Pump efficiency and leakage: The oil film pressure characteristics directly affect the overall efficiency of the axial piston pump. Sufficient oil film pressure helps to reduce frictional losses and minimize internal leakage, thereby increasing the efficiency of the pump. Conversely, insufficient oil film pressure can lead to increased leakage, reduced efficiency and potential damage to pump components. 7. Surface roughness and texture: The surface roughness and texture of the sliding parts in the axial piston pump have a significant impact on the oil film pressure characteristics. Proper surface finish and texture can enhance oil film formation, reduce friction, and improve lubricant distribution and retention. Surface treatments such as honing or coating can be performed to achieve the desired surface properties. 8. Oil viscosity: The viscosity of lubricating oil affects the oil film pressure characteristics in axial piston pumps. Proper selection of oil viscosity ensures adequate lubrication, optimum film thickness and proper film pressure distribution. Operating conditions, such as temperature and speed, should be considered when selecting the proper oil viscosity. 90R180-HF-5-AB-80-S-M-C8-J-03-NNN-23-23-24 90R180HF5AB80SMC8J03NNN232324 90-R-180-HF-5-AB-80-S-M-C8-J-03-NNN-23-23-24 90R180HF5AB80SMC8J03NNN232324 90R180-HF-5-AB-80-S-M-C8-J-03-NNN-32-32-24 90R180HF5AB80SMC8J03NNN323224 90-R-180-HF-5-AB-80-S-M-C8-J-03-NNN-32-32-24 90R180HF5AB80SMC8J03NNN323224 90R180-HF-5-AB-80-S-M-C8-J-05-NNN-32-32-26 90R180HF5AB80SMC8J05NNN323226 90-R-180-HF-5-AB-80-S-M-C8-J-05-NNN-32-32-26 90R180HF5AB80SMC8J05NNN323226 90R180-HF-5-AB-80-T-M-C8-J-03-FAC-32-32-24 90R180HF5AB80TMC8J03FAC323224 90-R-180-HF-5-AB-80-T-M-C8-J-03-FAC-32-32-24 90R180HF5AB80TMC8J03FAC323224 90R180-HF-5-AB-80-T-M-C8-J-03-FAC-35-35-24 90R180HF5AB80TMC8J03FAC353524 90-R-180-HF-5-AB-80-T-M-C8-J-03-FAC-35-35-24 90R180HF5AB80TMC8J03FAC353524 90R180-HF-5-BC-80-S-C-C8-J-03-NNN-29-29-28 90R180HF5BC80SCC8J03NNN292928 90-R-180-HF-5-BC-80-S-C-C8-J-03-NNN-29-29-28 90R180HF5BC80SCC8J03NNN292928 90R180-HF-5-BC-80-S-M-C8-H-03-NNN-26-26-24 90R180HF5BC80SMC8H03NNN262624 90-R-180-HF-5-BC-80-S-M-C8-H-03-NNN-26-26-24 90R180HF5BC80SMC8H03NNN262624 90R180-HF-5-BC-80-S-M-C8-J-03-FAC-23-23-24 90R180HF5BC80SMC8J03FAC232324 90-R-180-HF-5-BC-80-S-M-C8-J-03-FAC-23-23-24 90R180HF5BC80SMC8J03FAC232324 90R180-HF-5-BC-80-S-M-C8-J-03-NNN-29-29-24 90R180HF5BC80SMC8J03NNN292924 90-R-180-HF-5-BC-80-S-M-C8-J-03-NNN-29-29-24 90R180HF5BC80SMC8J03NNN292924 90R180-HF-5-BC-80-S-M-C8-J-03-NNN-35-35-24 90R180HF5BC80SMC8J03NNN353524 90-R-180-HF-5-BC-80-S-M-C8-J-03-NNN-35-35-24 90R180HF5BC80SMC8J03NNN353524 9. Pressure pulsation: The axial piston pump will have pressure pulsation, which refers to the small fluctuation of the oil film pressure during the operation of the pump. These fluctuations can be caused by a variety of factors, including the interaction between the piston and cylinder, pulsations in the hydraulic system, and flow changes. Minimizing pressure pulsations is important to ensure smooth and consistent operation, reduce noise and minimize the possibility of component wear. 10. Oil film pressure control: In some advanced axial piston pumps, the oil film pressure control mechanism can be combined to optimize the oil film pressure characteristics. These mechanisms may include pressure compensators, feedback control loops, or variable displacement features. By actively regulating oil film pressure, these control mechanisms help maintain optimum lubrication conditions and improve overall pump efficiency and performance. 11. Thermal effect: The oil film pressure characteristics of the axial piston pump will be affected by the thermal effect. When the pump is running, heat is generated due to friction and other factors. This heat affects the viscosity of the oil, which in turn affects the oil film pressure. Appropriate cooling mechanisms such as oil coolers or thermal management systems can be employed to control temperature and maintain desired oil film pressure characteristics. 12. Material compatibility: The material compatibility of oil film pressure characteristics and pump components should be considered. Pressure levels and lubricant properties need to be compatible with the materials used to prevent excessive wear, corrosion or other forms of damage. Material selection and surface treatment are important considerations in ensuring long-term durability and reliable operation of axial piston pumps. 90R180-HF-5-BC-80-T-C-C8-J-03-NNN-42-42-24 90R180HF5BC80TCC8J03NNN424224 90-R-180-HF-5-BC-80-T-C-C8-J-03-NNN-42-42-24 90R180HF5BC80TCC8J03NNN424224 90R180-HF-5-BC-80-T-C-F1-H-03-NNN-29-29-24 90R180HF5BC80TCF1H03NNN292924 90-R-180-HF-5-BC-80-T-C-F1-H-03-NNN-29-29-24 90R180HF5BC80TCF1H03NNN292924 90R180-HF-5-CD-80-S-C-C8-H-03-NNN-32-32-28 90R180HF5CD80SCC8H03NNN323228 90-R-180-HF-5-CD-80-S-C-C8-H-03-NNN-32-32-28 90R180HF5CD80SCC8H03NNN323228 90R180-HF-5-CD-80-S-C-C8-H-03-NNN-35-35-28 90R180HF5CD80SCC8H03NNN353528 90-R-180-HF-5-CD-80-S-C-C8-H-03-NNN-35-35-28 90R180HF5CD80SCC8H03NNN353528 90R180-HF-5-CD-80-S-M-F1-H-03-NNN-17-17-22 90R180HF5CD80SMF1H03NNN171722 90-R-180-HF-5-CD-80-S-M-F1-H-03-NNN-17-17-22 90R180HF5CD80SMF1H03NNN171722 90R180-HF-5-CD-80-T-C-C8-J-04-NNN-35-35-24 90R180HF5CD80TCC8J04NNN353524 90-R-180-HF-5-CD-80-T-C-C8-J-04-NNN-35-35-24 90R180HF5CD80TCC8J04NNN353524 90R180-HF-5-CD-80-T-C-F1-H-03-FAC-35-35-24 90R180HF5CD80TCF1H03FAC353524 90-R-180-HF-5-CD-80-T-C-F1-H-03-FAC-35-35-24 90R180HF5CD80TCF1H03FAC353524 90R180-HF-5-CD-80-T-C-F1-H-03-NNN-35-35-24 90R180HF5CD80TCF1H03NNN353524 90-R-180-HF-5-CD-80-T-C-F1-H-03-NNN-35-35-24 90R180HF5CD80TCF1H03NNN353524 90R180-HF-5-CD-80-T-C-F1-J-03-FAC-35-35-24 90R180HF5CD80TCF1J03FAC353524 90-R-180-HF-5-CD-80-T-C-F1-J-03-FAC-35-35-24 90R180HF5CD80TCF1J03FAC353524 90R180-HF-5-CD-80-T-M-C8-H-04-NNN-35-35-24 90R180HF5CD80TMC8H04NNN353524 90-R-180-HF-5-CD-80-T-M-C8-H-04-NNN-35-35-24 90R180HF5CD80TMC8H04NNN353524 13.
