Hydraulic backlash in an axial piston pump is the undesired backlash or movement of pump components when flow direction or load conditions change. It can cause pumping system inefficiency, vibration and potential damage. Controlling hydraulic clearances is critical to maintaining smooth operation and precise control of pumps. The following are some common methods of controlling hydraulic clearances in axial piston pumps: 1. Preload mechanism: An effective way to control hydraulic clearance is to use a preload mechanism. This mechanism applies a preload on the pump components to eliminate or reduce play between them. It may involve the use of springs, hydraulic accumulators, or mechanical elements that create a constant force to keep parts engaged. By eliminating free play, backlash is minimized, improving control and reducing vibration. 2. Control algorithm: advanced control algorithm can be implemented to actively compensate hydraulic clearance. These algorithms monitor pump health, including flow, pressure, and load, and adjust control signals accordingly to compensate for backlash. By continuously adjusting the control input, the algorithm minimizes the impact of clearances on pump performance and improves overall control accuracy. 3. Feedback Control: Implementing a feedback control system can help alleviate hydraulic lash. By incorporating position or pressure sensors into a pump system, the actual position or pressure of a pump component can be measured and compared to expected values. The feedback signal can then be used to adjust the control input, compensating for any detected backlash and maintaining desired performance. 90R180-KP-1-BC-80-T-M-F1-J-03-FAC-35-35-24 90R180KP1BC80TMF1J03FAC353524 90-R-180-KP-1-BC-80-T-M-F1-J-03-FAC-35-35-24 90R180KP1BC80TMF1J03FAC353524 90-R-180-KP-1-CD-80-S-M-F1-J-03-FAC-42-42-28 90R180KP1CD80SMF1J03FAC424228 90R180-KP-1-CD-80-T-C-C8-J-09-FAC-42-42-24 90R180KP1CD80TCC8J09FAC424224 90-R-180-KP-1-CD-80-T-C-C8-J-09-FAC-42-42-24 90R180KP1CD80TCC8J09FAC424224 90-R-180-KP-1-CD-80-T-C-F1-J-03-FAC-32-32-24 90R180KP1CD80TCF1J03FAC323224 90-R-180-KP-1-CD-80-T-C-F1-J-03-NNN-32-32-24 90R180KP1CD80TCF1J03NNN323224 90R180-KP-1-CD-80-T-M-F1-H-00-FAC-36-36-24 90R180KP1CD80TMF1H00FAC363624 90-R-180-KP-1-CD-80-T-M-F1-H-00-FAC-36-36-24 90R180KP1CD80TMF1H00FAC363624 90R180-KP-1-CD-80-T-M-F1-H-03-FAC-36-36-24 90R180KP1CD80TMF1H03FAC363624 90-R-180-KP-1-CD-80-T-M-F1-H-03-FAC-36-36-24 90R180KP1CD80TMF1H03FAC363624 90R180-KP-1-DE-80-T-C-F1-J-00-FAC-42-42-24 90R180KP1DE80TCF1J00FAC424224 90-R-180-KP-1-DE-80-T-C-F1-J-00-FAC-42-42-24 90R180KP1DE80TCF1J00FAC424224 90R180-KP-1-EF-80-T-M-C8-H-03-FAC-38-38-24 90R180KP1EF80TMC8H03FAC383824 90-R-180-KP-1-EF-80-T-M-C8-H-03-FAC-38-38-24 90R180KP1EF80TMC8H03FAC383824 90R180-KP-1-EG-80-T-C-C8-H-03-FAC-29-29-24 90R180KP1EG80TCC8H03FAC292924 90-R-180-KP-1-EG-80-T-C-C8-H-03-FAC-29-29-24 90R180KP1EG80TCC8H03FAC292924 90R180-KP-1-NN-80-T-C-F1-J-03-FAC-38-38-24 90R180KP1NN80TCF1J03FAC383824 90-R-180-KP-1-NN-80-T-C-F1-J-03-FAC-38-38-24 90R180KP1NN80TCF1J03FAC383824 90R180-KP-1-NN-80-T-M-F1-H-03-FAC-38-38-24 90R180KP1NN80TMF1H03FAC383824 4. Mechanical design optimization: The design of pump components can be optimized to minimize hydraulic clearance. This can include reducing backlash, increasing component tolerances, and employing anti-backlash features. Hydraulic backlash can be significantly reduced by ensuring tight tolerances and minimizing free play between components. Materials, manufacturing processes and part geometry need to be carefully considered during the design phase to achieve the desired clearance control. 5. System damping: Damping technology can be used to reduce the impact of hydraulic clearance. Damping elements, such as shock absorbers or hydraulic dampers, can be strategically placed within pumping systems to absorb and dissipate clearance-related energy. This helps minimize the magnitude and duration of backlash-induced vibrations, resulting in smoother operation and improved control. 6. System stiffness: Increasing the overall stiffness of the pump system helps minimize hydraulic clearance. This includes using rigid materials, optimizing part geometry, and reinforcing critical areas prone to gaps. By increasing stiffness, the pump system is less prone to deformation and play, thereby reducing backlash and improving control accuracy. 7. Maintenance and inspection: The regular maintenance and inspection of the axial piston pump is very important to control the hydraulic clearance. This includes checking and adjusting the preload mechanism, ensuring proper lubrication, and identifying any worn or damaged components that may be causing increased backlash. By keeping the pump system in good working order, the effects of hydraulic clearances can be minimized. 90-R-180-KP-1-NN-80-T-M-F1-H-03-FAC-38-38-24 90R180KP1NN80TMF1H03FAC383824 90R180-KP-2-AB-80-S-C-F1-H-00-NNN-26-26-26 90R180KP2AB80SCF1H00NNN262626 90-R-180-KP-2-AB-80-S-C-F1-H-00-NNN-26-26-26 90R180KP2AB80SCF1H00NNN262626 90R180-KP-2-NN-80-T-M-F1-H-03-FAC-35-35-24 90R180KP2NN80TMF1H03FAC353524 90-R-180-KP-2-NN-80-T-M-F1-H-03-FAC-35-35-24 90R180KP2NN80TMF1H03FAC353524 90R180-KP-5-AB-80-T-C-F1-H-00-NNN-35-35-22 90R180KP5AB80TCF1H00NNN353522 90-R-180-KP-5-AB-80-T-C-F1-H-00-NNN-35-35-22 90R180KP5AB80TCF1H00NNN353522 90R180-KP-5-AB-80-T-C-F1-J-03-NNN-32-32-24 90R180KP5AB80TCF1J03NNN323224 90-R-180-KP-5-AB-80-T-C-F1-J-03-NNN-32-32-24 90R180KP5AB80TCF1J03NNN323224 90R180-KP-5-AB-80-T-M-F1-J-03-FAC-38-38-24 90R180KP5AB80TMF1J03FAC383824 90-R-180-KP-5-AB-80-T-M-F1-J-03-FAC-38-38-24 90R180KP5AB80TMF1J03FAC383824 90R180-KP-5-BB-80-T-M-C8-J-03-FAC-38-38-24 90R180KP5BB80TMC8J03FAC383824 90-R-180-KP-5-BB-80-T-M-C8-J-03-FAC-38-38-24 90R180KP5BB80TMC8J03FAC383824 90R180-KP-5-BC-80-T-C-F1-H-03-FAC-45-45-24 90R180KP5BC80TCF1H03FAC454524 90-R-180-KP-5-BC-80-T-C-F1-H-03-FAC-45-45-24 90R180KP5BC80TCF1H03FAC454524 90R180-KP-5-BC-80-T-C-F1-J-03-FAC-29-29-24 90R180KP5BC80TCF1J03FAC292924 90-R-180-KP-5-BC-80-T-C-F1-J-03-FAC-29-29-24 90R180KP5BC80TCF1J03FAC292924 90R180-KP-5-BC-80-T-C-F1-J-03-FAC-35-35-24 90R180KP5BC80TCF1J03FAC353524 90-R-180-KP-5-BC-80-T-C-F1-J-03-FAC-35-35-24 90R180KP5BC80TCF1J03FAC353524 90R180-KP-5-BC-80-T-C-F1-J-03-FAC-38-38-24 90R180KP5BC80TCF1J03FAC383824 8. Dynamic compensation: Dynamic compensation technology can be used to actively offset the influence of hydraulic clearance. This involves continuously monitoring system dynamics and applying compensating forces or adjustments to counter backlash-induced motion. These compensatory actions can be achieved through the use of advanced control algorithms and actuators that can respond quickly to changes in the system. 9. Reduced Friction: Minimizing friction within the pump system helps control hydraulic clearances. Friction exacerbates the effects of backlash by exacerbating backlash and motion between components. Techniques such as improved lubrication, optimized bearing design and reduced surface roughness can help reduce friction and thereby reduce backlash. 10. System Optimization: A holistic approach to system optimization helps control hydraulic clearances. This involves considering the entire pumping system, including the pump, controls, valves and associated components. By optimizing the design, integration and interaction of these elements, the system can better handle hydraulic clearances and maintain precise control. 11. Load sensing and control: Implementing a load sensing and control mechanism can help mitigate the effects of hydraulic clearance. Load sensing allows the pump to adjust its output based on load demand, while load control regulates pressure or flow to maintain consistent performance. By actively monitoring and adapting to changes in load, the system can compensate for the effects of backlash and provide smoother operation. 90-R-180-KP-5-BC-80-T-C-F1-J-03-FAC-38-38-24 90R180KP5BC80TCF1J03FAC383824 90R180-KP-5-CD-80-T-C-C8-J-03-EBA-35-35-24 90R180KP5CD80TCC8J03EBA353524 90-R-180-KP-5-CD-80-T-C-C8-J-03-EBA-35-35-24 90R180KP5CD80TCC8J03EBA353524 90R180-KP-5-CD-80-T-C-F1-H-03-FAC-20-20-24 90R180KP5CD80TCF1H03FAC202024 90-R-180-KP-5-CD-80-T-C-F1-H-03-FAC-20-20-24 90R180KP5CD80TCF1H03FAC202024 90R180-KP-5-CD-80-T-C-F1-H-03-FAC-35-35-24 90R180KP5CD80TCF1H03FAC353524 90-R-180-KP-5-CD-80-T-C-F1-H-03-FAC-35-35-24 90R180KP5CD80TCF1H03FAC353524 90R180-KP-5-CD-80-T-C-F1-H-03-NNN-42-42-24 90R180KP5CD80TCF1H03NNN424224 90-R-180-KP-5-CD-80-T-C-F1-H-03-NNN-42-42-24 90R180KP5CD80TCF1H03NNN424224 90R180-KP-5-CD-80-T-C-F1-J-03-FAC-23-23-28 90R180KP5CD80TCF1J03FAC232328 90-R-180-KP-5-CD-80-T-C-F1-J-03-FAC-23-23-28 90R180KP5CD80TCF1J03FAC232328 90R180-KP-5-CD-80-T-M-C8-H-03-FAC-38-38-24 90R180KP5CD80TMC8H03FAC383824 90-R-180-KP-5-CD-80-T-M-C8-H-03-FAC-38-38-24 90R180KP5CD80TMC8H03FAC383824 90R180-KP-5-CD-80-T-M-C8-H-03-NNN-42-42-24 90R180KP5CD80TMC8H03NNN424224 90-R-180-KP-5-CD-80-T-M-C8-H-03-NNN-42-42-24 90R180KP5CD80TMC8H03NNN424224 90R180-KP-5-CD-80-T-M-C8-J-03-FAC-38-38-24 90R180KP5CD80TMC8J03FAC383824 90-R-180-KP-5-CD-80-T-M-C8-J-03-FAC-38-38-24 90R180KP5CD80TMC8J03FAC383824 90R180-KP-5-CD-80-T-M-C8-J-03-NNN-26-26-26 90R180KP5CD80TMC8J03NNN262626 90-R-180-KP-5-CD-80-T-M-C8-J-03-NNN-26-26-26 90R180KP5CD80TMC8J03NNN262626 90R180-KP-5-CD-80-T-M-C8-J-03-NNN-32-32-26 90R180KP5CD80TMC8J03NNN323226 12. System damping and isolation: Adding damping and isolation elements to the pump system can help absorb and mitigate the effects of hydraulic clearances.
