The orifice in the distribution plate of an axial piston pump has a significant effect on the cavitation characteristics of the pump. Here are some key points to consider regarding the impact of orifices on cavitation: 1. Prevent cavitation: Cavitation occurs when the pressure of a fluid is lower than its vapor pressure, causing the formation and rupture of vapor bubbles. Cavitation can lead to reduced performance, corrosion and damage to pump components. Orifices are often included in distribution plates to help prevent or mitigate the effects of cavitation. 2. Pressure recovery: The orifice can improve the pressure recovery in the pump, especially during the transition from low pressure area to high pressure area. They act as flow restrictors, slowing the flow rate and allowing pressure to recover before reaching the pump outlet. This helps reduce cavitation by maintaining high fluid pressure. 3. Flow stability: The orifice can enhance the flow stability in the pump. By controlling flow and pressure distribution, they help reduce flow fluctuations and turbulence that can lead to cavitation. Orifices provide a means of regulating and stabilizing flow to minimize the risk of cavitation. 4. Damping effect: The size, shape and position of the damping hole will affect its effect of reducing cavitation. A properly designed orifice should provide adequate flow restriction and pressure recovery while minimizing flow loss. Computational fluid dynamics (CFD) analysis and experimental testing help to optimize the parameters of the orifice to improve cavitation performance. 90-R-180-KA-5-CD-80-T-M-C8-J-00-NNN-38-38-24 90R180KA5CD80TMC8J00NNN383824 90R180-KA-5-CD-80-T-M-C8-J-03-EBA-42-42-24 90R180KA5CD80TMC8J03EBA424224 90-R-180-KA-5-CD-80-T-M-C8-J-03-EBA-42-42-24 90R180KA5CD80TMC8J03EBA424224 90R180-KA-5-CD-80-T-M-C8-J-03-NNN-20-20-24 90R180KA5CD80TMC8J03NNN202024 90-R-180-KA-5-CD-80-T-M-C8-J-03-NNN-20-20-24 90R180KA5CD80TMC8J03NNN202024 90R180-KA-5-CD-80-T-M-C8-J-03-NNN-35-35-24 90R180KA5CD80TMC8J03NNN353524 90-R-180-KA-5-CD-80-T-M-C8-J-03-NNN-35-35-24 90R180KA5CD80TMC8J03NNN353524 90R180-KA-5-CD-80-T-M-C8-J-03-NNN-38-38-24 90R180KA5CD80TMC8J03NNN383824 90-R-180-KA-5-CD-80-T-M-C8-J-03-NNN-38-38-24 90R180KA5CD80TMC8J03NNN383824 90R180-KA-5-CD-80-T-M-C8-J-03-NNN-42-42-24 90R180KA5CD80TMC8J03NNN424224 90-R-180-KA-5-CD-80-T-M-C8-J-03-NNN-42-42-24 90R180KA5CD80TMC8J03NNN424224 90R180-KA-5-CD-80-T-M-F1-H-03-FAC-17-17-24 90R180KA5CD80TMF1H03FAC171724 90-R-180-KA-5-CD-80-T-M-F1-H-03-FAC-17-17-24 90R180KA5CD80TMF1H03FAC171724 90R180-KA-5-CD-80-T-M-F1-J-03-FAC-35-35-24 90R180KA5CD80TMF1J03FAC353524 90-R-180-KA-5-CD-80-T-M-F1-J-03-FAC-35-35-24 90R180KA5CD80TMF1J03FAC353524 90-R-180-KA-5-DE-80-D-C-C8-H-03-NNN-42-42-22 90R180KA5DE80DCC8H03NNN424222 90R180-KA-5-DE-80-S-C-C8-H-03-NNN-32-32-24 90R180KA5DE80SCC8H03NNN323224 90-R-180-KA-5-DE-80-S-C-C8-H-03-NNN-32-32-24 90R180KA5DE80SCC8H03NNN323224 90R180-KA-5-DE-80-S-C-C8-H-04-NNN-32-14-24 90R180KA5DE80SCC8H04NNN321424 90-R-180-KA-5-DE-80-S-C-C8-H-04-NNN-32-14-24 90R180KA5DE80SCC8H04NNN321424 5. Reduce cavitation noise: Orifices can also help reduce noise caused by cavitation. The presence of cavitation bubbles creates noise when they collapse, resulting in undesirable acoustics. The overall noise level of the pump can be reduced by reducing the occurrence and severity of cavitation through effective orifice design. 6. Material selection: The materials used for the distribution plate and damping hole should be carefully selected to ensure compatibility with the working fluid and the ability to resist cavitation damage. Materials with high strength, corrosion and erosion properties are generally preferred to withstand the harsh conditions associated with cavitation. 7. Optimization trade-offs: The design of orifices involves trade-offs that need to be considered. While orifices help reduce cavitation, they also introduce additional flow resistance and pressure loss. Optimizing the orifice configuration should involve a balance between preventing cavitation and maintaining acceptable pump performance in terms of flow, efficiency, and pressure characteristics. 8. The occurrence and severity of cavitation: The presence of damping holes will affect the occurrence and severity of cavitation in the pump. Well-designed orifices can delay or prevent cavitation by promoting smoother fluid flow and minimizing pressure drop. This helps maintain higher pressures within the pump, reducing the possibility of cavitation and its harmful effects. 9. Reduce erosion and wear: Cavitation causes erosion and wear of pump components, including the distribution plate. By employing orifices, localized pressure drops and fluid velocity fluctuations leading to cavitation are minimized. This helps extend the life of the distribution plate and other critical components of the pump. 90R180-KA-5-DE-80-S-C-C8-J-04-NNN-35-35-24 90R180KA5DE80SCC8J04NNN353524 90-R-180-KA-5-DE-80-S-C-C8-J-04-NNN-35-35-24 90R180KA5DE80SCC8J04NNN353524 90R180-KA-5-DE-80-S-M-C8-H-03-FAC-23-23-24 90R180KA5DE80SMC8H03FAC232324 90-R-180-KA-5-DE-80-S-M-C8-H-03-FAC-23-23-24 90R180KA5DE80SMC8H03FAC232324 90R180-KA-5-DE-80-S-M-C8-H-03-FAC-42-42-24 90R180KA5DE80SMC8H03FAC424224 90-R-180-KA-5-DE-80-S-M-C8-H-03-FAC-42-42-24 90R180KA5DE80SMC8H03FAC424224 90R180-KA-5-DE-80-T-C-C8-J-03-NNN-42-42-30 90R180KA5DE80TCC8J03NNN424230 90-R-180-KA-5-DE-80-T-C-C8-J-03-NNN-42-42-30 90R180KA5DE80TCC8J03NNN424230 90R180-KA-5-DE-80-T-M-C8-J-05-NNN-29-29-24 90R180KA5DE80TMC8J05NNN292924 90-R-180-KA-5-DE-80-T-M-C8-J-05-NNN-29-29-24 90R180KA5DE80TMC8J05NNN292924 90R180-KA-5-DE-80-T-M-F1-H-03-FAC-35-35-24 90R180KA5DE80TMF1H03FAC353524 90-R-180-KA-5-DE-80-T-M-F1-H-03-FAC-35-35-24 90R180KA5DE80TMF1H03FAC353524 90R180-KA-5-DE-80-T-M-F1-J-03-FAC-32-32-28 90R180KA5DE80TMF1J03FAC323228 90-R-180-KA-5-DE-80-T-M-F1-J-03-FAC-32-32-28 90R180KA5DE80TMF1J03FAC323228 90-R-180-KA-5-EF-80-D-C-C8-H-03-NNN-42-42-22 90R180KA5EF80DCC8H03NNN424222 90R180-KA-5-EF-80-D-C-C8-L-03-NNN-42-42-22 90R180KA5EF80DCC8L03NNN424222 90-R-180-KA-5-EF-80-D-C-C8-L-03-NNN-42-42-22 90R180KA5EF80DCC8L03NNN424222 90R180-KA-5-EF-80-D-M-C8-L-03-NNN-42-42-22 90R180KA5EF80DMC8L03NNN424222 90-R-180-KA-5-EF-80-D-M-C8-L-03-NNN-42-42-22 90R180KA5EF80DMC8L03NNN424222 90R180-KA-5-EF-80-S-C-C8-H-03-NNN-20-20-24 90R180KA5EF80SCC8H03NNN202024 10. Internal flow characteristics: The orifice affects the internal flow characteristics of the pump, including flow pattern, velocity distribution and pressure distribution. Properly designed orifices optimize flow behavior and reduce areas of low pressure and turbulence that lead to cavitation. This results in smoother flow and improved cavitation resistance. 11. Reduce vibration and noise: Vibration and noise caused by cavitation can be a significant challenge in pump operation. Orifices help dampen pressure pulsations and reduce vibration levels within the pump. This reduces noise generation and improves overall pump performance. 12. Optimization for specific applications: The effect of orifices on cavitation characteristics is largely dependent on the specific application and operating conditions. Factors such as fluid properties, system pressure, temperature, and flow should be considered when optimizing the orifice design. Computational modeling such as CFD simulations can be used to evaluate different orifice configurations and optimize their performance for a given application. 13. Maintenance and maintenance: The design of the damping hole should take into account the requirements of maintenance and maintenance. Easy access to the orifice and the ability to clean or replace it if necessary helps ensure its long-term effectiveness in mitigating cavitation. It should be noted that the design and optimization of orifices for cavitation characteristics should be based on a thorough understanding of the specific pump system and operating conditions. Working with pump manufacturers, fluid dynamics experts and experienced engineers can provide valuable insight and assistance in optimizing orifice designs to minimize cavitation effects in axial piston pumps.
