The value of erosion damage for an orifice in an axial piston pump valve plate can depend on factors such as operating conditions, fluid properties, and the design and material of the valve plate. However, specific values for erosion damage are not usually provided as standard references. Here are some key points about erosion damage to valve plate orifices: 1. Orifice corrosion: The orifice on the valve plate of an axial piston pump plays a vital role in controlling fluid flow and pressure fluctuations. These holes allow fluid to flow between different chambers or sections of the pump to dampen pressure pulsations. However, the high velocity of fluid flow through an orifice can cause erosion over time, leading to material loss and potential damage. 2. Erosion Mechanisms: Erosion in orifices can occur due to a variety of mechanisms including cavitation erosion, particle erosion, or high velocity fluid impact. Cavitational erosion occurs when gas bubbles collapse near the surface, causing localized pressure spikes to erode the material. Particle erosion occurs when solid particles in a fluid strike a surface and gradually wear away the surface. High-velocity fluid impact can also cause erosion by directly hitting a surface with enormous force. 90R100-KA-5-BC-80-P-4-S1-E-04-GBA-42-42-24 90R100KA5BC80P4S1E04GBA424224 90-R-100-KA-5-BC-80-P-3-S1-E-03-GBA-26-26-24 90R100KA5BC80P3S1E03GBA262624 90R100-KA-5-BC-80-P-3-S1-E-03-GBA-26-26-24 90R100KA5BC80P3S1E03GBA262624 90-R-100-KA-5-BC-80-P-3-F1-E-03-GBA-35-35-24-G005 90R100KA5BC80P3F1E03GBA353524G005 90R100-KA-5-BC-80-P-3-F1-E-03-GBA-35-35-24-G005 90R100KA5BC80P3F1E03GBA353524G005 90-R-100-KA-5-BC-80-P-3-C7-E-04-GBA-45-45-24 90R100KA5BC80P3C7E04GBA454524 90R100-KA-5-BC-80-P-3-C7-E-04-GBA-45-45-24 90R100KA5BC80P3C7E04GBA454524 90-R-100-KA-5-BC-80-P-3-C7-E-03-GBA-42-42-24 90R100KA5BC80P3C7E03GBA424224 90R100-KA-5-BC-80-P-3-C7-E-03-GBA-42-42-24 90R100KA5BC80P3C7E03GBA424224 90-R-100-KA-5-BC-80-L-4-T2-E-03-GBA-35-35-24 90R100KA5BC80L4T2E03GBA353524 90R100-KA-5-BC-80-L-4-T2-E-03-GBA-35-35-24 90R100KA5BC80L4T2E03GBA353524 90-R-100-KA-5-BC-80-L-4-T2-E-03-GBA-32-32-24 90R100KA5BC80L4T2E03GBA323224 90R100-KA-5-BC-80-L-4-T2-E-03-GBA-32-32-24 90R100KA5BC80L4T2E03GBA323224 90-R-100-KA-5-BC-80-L-4-C7-E-05-GBA-29-29-24 90R100KA5BC80L4C7E05GBA292924 90R100-KA-5-BC-80-L-4-C7-E-05-GBA-29-29-24 90R100KA5BC80L4C7E05GBA292924 90-R-100-KA-5-BC-80-L-4-C7-E-03-GBA-42-42-24 90R100KA5BC80L4C7E03GBA424224 90R100-KA-5-BC-80-L-4-C7-E-03-GBA-42-42-24 90R100KA5BC80L4C7E03GBA424224 90-R-100-KA-5-BC-80-L-3-S1-D-03-GBA-42-42-24 90R100KA5BC80L3S1D03GBA424224 90R100-KA-5-BC-80-L-3-S1-D-03-GBA-42-42-24 90R100KA5BC80L3S1D03GBA424224 90-R-100-KA-5-BC-80-L-3-F1-F-00-GBA-20-20-28 90R100KA5BC80L3F1F00GBA202028 3. Influencing factors: The severity of corrosion damage to the damping hole is affected by many factors, including fluid properties (such as viscosity and degree of contamination), pump operating conditions (such as pressure, flow and temperature), valve plate design (including the shape of the damping hole and size), and the material used for the disc. 4. Mitigation Strategies: In order to minimize erosion damage in orifices, various strategies can be employed. These include using corrosion-resistant materials for valve plates, optimizing orifice designs to reduce flow velocity and turbulence, maintaining proper fluid cleanliness and viscosity, and ensuring pump operating conditions are within recommended ranges. 5. Inspection and Maintenance: Regular inspection of the valve plate and orifice is essential to discover any corrosion damage and take appropriate corrective action. Maintenance practices may include cleaning the orifice, repairing or replacing the valve plate if corrosion damage is severe, and monitoring fluid properties and operating conditions to minimize corrosion risk. 6. Performance degradation: The corrosion damage of the damping hole will cause the performance degradation of the axial piston pump. As erosion progresses, the geometry of the orifice may change, affecting flow characteristics and the effectiveness of pressure pulsation damping. This results in increased pressure fluctuations, reduced pump efficiency, and decreased overall system performance. 7. Material selection: The selection of valve plate material is crucial to mitigate erosion damage. The valve plate should be made of a material with good corrosion resistance, such as hardened steel, ceramic or composite material. The erosion resistance of a material depends on factors such as hardness, toughness, and resistance to cavitation and particle impact. 90-R-100-KA-5-BC-80-L-3-C7-E-03-GBA-42-42-24 90R100KA5BC80L3C7E03GBA424224 90R100-KA-5-BC-80-L-3-C7-E-03-GBA-42-42-24 90R100KA5BC80L3C7E03GBA424224 90-R-100-KA-5-BC-80-L-3-C7-E-03-GBA-30-30-24 90R100KA5BC80L3C7E03GBA303024 90R100-KA-5-BC-80-L-3-C7-E-03-GBA-30-30-24 90R100KA5BC80L3C7E03GBA303024 90-R-100-KA-5-BC-60-S-4-S1-F-04-GBA-42-42-24 90R100KA5BC60S4S1F04GBA424224 90R100-KA-5-BC-60-S-4-S1-F-04-GBA-42-42-24 90R100KA5BC60S4S1F04GBA424224 90-R-100-KA-5-BC-60-S-4-S1-E-03-GBA-35-35-24 90R100KA5BC60S4S1E03GBA353524 90R100-KA-5-BC-60-S-4-S1-E-03-GBA-35-35-24 90R100KA5BC60S4S1E03GBA353524 90-R-100-KA-5-BC-60-S-4-C7-E-03-GBA-42-42-24 90R100KA5BC60S4C7E03GBA424224 90R100-KA-5-BC-60-S-4-C7-E-03-GBA-42-42-24 90R100KA5BC60S4C7E03GBA424224 90-R-100-KA-5-BC-60-S-3-T2-E-03-GBA-42-42-30 90R100KA5BC60S3T2E03GBA424230 90R100-KA-5-BC-60-S-3-T2-E-03-GBA-42-42-30 90R100KA5BC60S3T2E03GBA424230 90-R-100-KA-5-BC-60-S-3-S1-F-03-GBA-42-42-24 90R100KA5BC60S3S1F03GBA424224 90R100-KA-5-BC-60-S-3-S1-F-03-GBA-42-42-24 90R100KA5BC60S3S1F03GBA424224 90-R-100-KA-5-BC-60-S-3-C7-E-03-GBA-42-42-24 90R100KA5BC60S3C7E03GBA424224 90R100-KA-5-BC-60-S-3-C7-E-03-GBA-42-42-24 90R100KA5BC60S3C7E03GBA424224 90-R-100-KA-5-BC-60-S-3-C7-E-03-GBA-38-38-24 90R100KA5BC60S3C7E03GBA383824 90R100-KA-5-BC-60-S-3-C7-E-03-GBA-38-38-24 90R100KA5BC60S3C7E03GBA383824 90-R-100-KA-5-BC-60-S-3-C7-E-03-GBA-35-35-24 90R100KA5BC60S3C7E03GBA353524 90R100-KA-5-BC-60-S-3-C7-E-03-GBA-35-35-24 90R100KA5BC60S3C7E03GBA353524 8.
