The leakage clearance of a scroll hydraulic pump has an important influence on the flow field and performance of the pump. Leakage gaps are small gaps between the scroll wraps that allow a certain amount of fluid to leak from the high pressure area to the low pressure area within the pump. The following are some of the main effects of leakage clearance on the flow field and performance of a scroll hydraulic pump: 1. Flow and pressure pulsation: The leakage gap affects the flow and pressure pulsation in the pump. Larger leak gaps allow more fluid to leak from high pressure areas back to low pressure areas, reducing effective flow rates and increasing pressure pulsations. This can lead to reduced pump performance and increased vibration and noise levels. 2. Internal recirculation: The leakage gap affects the internal recirculation of the fluid in the pump. When fluid leaks from a high-pressure area to a low-pressure area, it creates internal recirculation paths that affect flow patterns and pressure distribution. Excessive internal recirculation can result in energy loss, reduced efficiency and reduced overall pump performance. 3. Efficiency and volume loss: The leakage gap will cause the volume loss of the pump. When fluid leaks back, it bypasses the intended flow path, resulting in inefficiency and loss of volumetric efficiency. The leakage gap increases the internal leakage flow, which can negatively affect the overall efficiency of the pump, especially at higher pressures and flow rates. 90-R-100-HF-1-NN-60-R-3-S1-E-03-GBA-35-35-24 90R100HF1NN60R3S1E03GBA353524 90-R-100-HF-1-NN-60-P-4-S1-E-03-GBA-29-29-24 90R100HF1NN60P4S1E03GBA292924 90-R-100-HF-1-CD-80-S-4-C6-F-00-GBA-38-38-24 90R100HF1CD80S4C6F00GBA383824 90R100-HF-1-CD-80-S-4-C6-F-00-GBA-38-38-24 90R100HF1CD80S4C6F00GBA383824 90-R-100-HF-1-CD-80-S-3-S1-F-00-GBA-23-29-24 90R100HF1CD80S3S1F00GBA232924 90-R-100-HF-1-CD-80-S-3-F1-F-00-GBA-23-29-24 90R100HF1CD80S3F1F00GBA232924 90-R-100-HF-1-CD-80-R-4-F1-F-03-GBA-35-35-24 90R100HF1CD80R4F1F03GBA353524 90-R-100-HF-1-CD-80-R-4-F1-F-00-GBA-32-26-30 90R100HF1CD80R4F1F00GBA322630 90R100-HF-1-CD-80-R-4-F1-F-00-GBA-32-26-30 90R100HF1CD80R4F1F00GBA322630 90-R-100-HF-1-CD-80-R-4-C6-F-04-GBA-42-42-24 90R100HF1CD80R4C6F04GBA424224 90-R-100-HF-1-CD-80-R-3-F1-F-00-GBA-32-26-30 90R100HF1CD80R3F1F00GBA322630 90-R-100-HF-1-CD-80-P-3-F1-F-00-GBA-32-29-30 90R100HF1CD80P3F1F00GBA322930 90-R-100-HF-1-CD-80-P-3-F1-F-00-GBA-23-29-24 90R100HF1CD80P3F1F00GBA232924 90-R-100-HF-1-CD-80-P-3-C7-F-03-GBA-35-35-24 90R100HF1CD80P3C7F03GBA353524 90-R-100-HF-1-CD-80-L-3-S1-F-00-GBA-23-23-24 90R100HF1CD80L3S1F00GBA232324 90R100-HF-1-CD-80-L-3-S1-F-00-GBA-23-23-24 90R100HF1CD80L3S1F00GBA232324 90-R-100-HF-1-CD-60-S-4-F1-E-03-GBA-42-42-24 90R100HF1CD60S4F1E03GBA424224 90R100-HF-1-CD-60-S-4-F1-E-03-GBA-42-42-24 90R100HF1CD60S4F1E03GBA424224 90-R-100-HF-1-CD-60-S-3-F1-E-03-GBA-42-42-24 90R100HF1CD60S3F1E03GBA424224 90-R-100-HF-1-CD-60-R-4-S1-E-03-GBA-42-42-24 90R100HF1CD60R4S1E03GBA424224 4. Wear and sealing effect: The size and condition of the leakage gap affect the wear and sealing performance of the scroll. Larger leakage clearances cause more scroll wear due to increased fluid turbulence and friction. In addition, if the leakage gap is too large, the sealing effect between the scrolls may be affected, resulting in higher internal leakage and reduced pump performance. 5. Flow field and leakage distribution: The leakage gap affects the flow field and distribution of leakage in the pump. The size and shape of the gap affects flow patterns, vortex formation and pressure distribution. Proper design and optimization of the leakage gap geometry is critical to achieving a balanced and controlled flow field, minimizing energy loss and maximizing pump performance. 6. Leakage control strategy: The influence of leakage clearance has led to the development of various leakage control strategies in scroll hydraulic pumps. These strategies are designed to minimize leaky traffic and its impact on performance. Approaches include improving sealing mechanisms, using compliant materials, optimizing gap geometry, and implementing flow control devices. These strategies help reduce leakage losses, increase efficiency and improve overall pump performance. 7. Losses caused by leakage: Leakage gaps will cause losses in the pump. Fluid leaking from a high pressure area to a low pressure area experiences a pressure drop and energy dissipation. Losses caused by these leaks can reduce the overall efficiency of the pump and have a significant impact on its performance, especially at high operating pressures and flow rates. 90-R-100-HF-1-CD-60-R-3-T2-E-03-GBA-42-42-20 90R100HF1CD60R3T2E03GBA424220 90-R-100-HF-1-CD-60-P-3-T2-E-03-GBA-42-42-20 90R100HF1CD60P3T2E03GBA424220 90-R-100-HF-1-CD-60-P-3-S1-F-03-GBA-38-38-24 90R100HF1CD60P3S1F03GBA383824 90-R-100-HF-1-CD-60-P-3-S1-E-03-GBA-42-42-20 90R100HF1CD60P3S1E03GBA424220 90-R-100-HF-1-CD-60-P-3-F1-F-03-GBA-38-38-24 90R100HF1CD60P3F1F03GBA383824 90-R-100-HF-1-CD-60-P-3-F1-E-03-GBA-38-38-20 90R100HF1CD60P3F1E03GBA383820 90-R-100-HF-1-CD-60-D-3-C7-L-03-GBA-38-38-24 90R100HF1CD60D3C7L03GBA383824 90-R-100-HF-1-BC-80-S-4-S1-F-03-GBA-30-30-24 90R100HF1BC80S4S1F03GBA303024 90R100-HF-1-BC-80-S-4-S1-F-03-GBA-30-30-24 90R100HF1BC80S4S1F03GBA303024 90-R-100-HF-1-BC-80-S-4-F1-E-03-GBA-35-35-20 90R100HF1BC80S4F1E03GBA353520 90-R-100-HF-1-BC-80-S-4-F1-E-03-GBA-29-29-24 90R100HF1BC80S4F1E03GBA292924 90-R-100-HF-1-BC-80-S-4-F1-E-03-GBA-17-17-20 90R100HF1BC80S4F1E03GBA171720 90-R-100-HF-1-BC-80-S-4-C7-E-03-GBA-38-38-24 90R100HF1BC80S4C7E03GBA383824 90R100-HF-1-BC-80-S-4-C7-E-03-GBA-38-38-24 90R100HF1BC80S4C7E03GBA383824 90-R-100-HF-1-BC-80-S-3-S1-F-03-GBA-35-35-24 90R100HF1BC80S3S1F03GBA353524 90-R-100-HF-1-BC-80-S-3-S1-E-04-GBA-32-32-24 90R100HF1BC80S3S1E04GBA323224 90-R-100-HF-1-BC-80-S-3-S1-E-03-GBA-42-42-24 90R100HF1BC80S3S1E03GBA424224 90-R-100-HF-1-BC-80-S-3-F1-E-03-GBA-35-35-24 90R100HF1BC80S3F1E03GBA353524 90-R-100-HF-1-BC-80-S-3-C7-E-03-GBA-38-38-24 90R100HF1BC80S3C7E03GBA383824 90R100-HF-1-BC-80-S-3-C7-E-03-GBA-38-38-24 90R100HF1BC80S3C7E03GBA383824 8. Pressure distribution and sealing effect: The leakage gap affects the pressure distribution in the pump. Larger leak gaps result in uneven pressure distribution, with higher pressure near the inlet and lower pressure near the outlet. This affects the sealing effectiveness of the scrolls and increases the possibility of leak paths, resulting in further energy loss and reduced pump performance. 9. Influence on flow uniformity: The existence of leakage gap will destroy the flow uniformity in the pump. Leaked fluid mixes with the main flow, causing turbulence and changes in flow velocity and direction. This results in uneven flow at the pump outlet, affecting the performance and stability of downstream hydraulic components and systems. 10. Noise and Vibration: Leakage gaps will increase the noise and vibration levels of the pump. Fluid leaks and the resulting turbulence create additional noise and induce vibrations that impact comfort, reliability and the overall user experience. Minimizing leak clearances and controlling fluid flow paths helps reduce noise and vibration levels. 11. Leakage optimization: In order to reduce the negative impact of leakage, optimization technology is adopted. These involve designing the geometry, size and clearance of the leak gap to balance the trade-off between minimizing leakage losses and maintaining seal effectiveness. The desired leakage gap characteristics can be achieved using advanced manufacturing techniques such as precision machining and tight tolerances. 90-R-100-HF-1-BC-80-R-4-S1-F-09-GBA-38-38-24 90R100HF1BC80R4S1F09GBA383824 90-R-100-HF-1-BC-80-R-4-S1-E-03-GBA-35-35-24 90R100HF1BC80R4S1E03GBA353524 90-R-100-HF-1-BC-80-R-3-S1-F-04-GBA-35-35-24 90R100HF1BC80R3S1F04GBA353524 90-R-100-HF-1-BC-80-R-3-S1-E-09-GBA-38-38-24 90R100HF1BC80R3S1E09GBA383824 90-R-100-HF-1-BC-80-P-4-S1-E-03-GBA-42-42-24 90R100HF1BC80P4S1E03GBA424224 90R100-HF-1-BC-80-P-4-C7-E-05-GBA-32-32-22 90R100HF1BC80P4C7E05GBA323222 90-R-100-HF-1-BC-80-P-3-S1-E-03-GBA-42-42-24 90R100HF1BC80P3S1E03GBA424224 90-R-100-HF-1-BC-80-L-4-F1-E-03-GBA-26-26-24 90R100HF1BC80L4F1E03GBA262624 90-R-100-HF-1-BC-80-L-3-S1-F-03-GBA-35-35-20 90R100HF1BC80L3S1F03GBA353520 90-R-100-HF-1-BC-80-L-3-S1-E-09-GBA-26-26-24 90R100HF1BC80L3S1E09GBA262624 90-R-100-HF-1-BC-80-L-3-C7-E-03-GBA-42-42-24 90R100HF1BC80L3C7E03GBA424224 90-R-100-HF-1-BC-61-S-3-S1-E-03-GBA-32-32-24 90R100HF1BC61S3S1E03GBA323224 90-R-100-HF-1-BC-60-S-4-F1-E-03-GBA-20-20-20 90R100HF1BC60S4F1E03GBA202020 90R100-HF-1-BC-60-S-4-F1-E-03-GBA-20-20-20 90R100HF1BC60S4F1E03GBA202020 90-R-100-HF-1-BC-60-S-3-F1-E-03-GBA-42-42-24 90R100HF1BC60S3F1E03GBA424224 90-R-100-HF-1-BC-60-S-3-C7-E-03-GBA-35-35-24 90R100HF1BC60S3C7E03GBA353524 90R100-HF-1-BC-60-S-3-C7-E-03-GBA-35-35-24 90R100HF1BC60S3C7E03GBA353524 90-R-100-HF-1-BC-60-R-4-S1-E-03-GBA-29-29-24 90R100HF1BC60R4S1E03GBA292924 90R100-HF-1-BC-60-R-4-S1-E-03-GBA-29-29-24 90R100HF1BC60R4S1E03GBA292924 90-R-100-HF-1-BC-60-R-3-F1-E-03-GBA-32-32-24 90R100HF1BC60R3F1E03GBA323224 12.
