Pressure compensation and constant flow control are the basic functions of axial piston pumps, which ensure the stable and reliable operation of the hydraulic system. Let's discuss each concept in more detail: Pressure Compensation: Pressure compensation is a mechanism employed in axial piston pumps to maintain a consistent output flow as system pressure changes. It ensures that the pump is able to deliver a constant flow regardless of changes in load pressure. The pressure compensating mechanism usually consists of a compensating valve located within the pump. It senses system pressure and adjusts the pump's swashplate angle to regulate output flow. As system pressure increases, the compensating valve redirects excess flow back to the pump inlet or low pressure line. This prevents the pump from being overloaded and maintains a constant flow. The compensation valve operates in a closed loop control system, continuously monitoring the system pressure and adjusting the pump output accordingly. It helps stabilize hydraulic systems by compensating for pressure changes and ensuring that desired flow is maintained. 90-R-130-KA-5-CD-80-S-4-F1-F-03-GBA-42-42-24 90R130KA5CD80S4F1F03GBA424224 90-R-130-KA-5-CD-80-S-4-F1-H-02-GBA-38-38-28 90R130KA5CD80S4F1H02GBA383828 90R130-KA-5-CD-80-S-4-F1-H-04-GBA-42-42-24 90R130KA5CD80S4F1H04GBA424224 90-R-130-KA-5-CD-80-S-4-F1-H-04-GBA-42-42-24 90R130KA5CD80S4F1H04GBA424224 90R130-KA-5-DE-80-D-4-C8-L-03-GBA-42-42-24 90R130KA5DE80D4C8L03GBA424224 90-R-130-KA-5-DE-80-D-4-C8-L-03-GBA-42-42-24 90R130KA5DE80D4C8L03GBA424224 90R130-KA-5-DE-80-L-3-C8-F-03-GBA-45-45-24 90R130KA5DE80L3C8F03GBA454524 90-R-130-KA-5-DE-80-L-3-C8-F-03-GBA-45-45-24 90R130KA5DE80L3C8F03GBA454524 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5DE80L3C8H03GBA292924 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5DE80L3C8H03GBA292924 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5DE80L3C8H03GBA353524 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5DE80L3C8H03GBA353524 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-38-38-24 90R130KA5DE80L3C8H03GBA383824 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5DE80L3C8H03GBA424224 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5DE80L3C8H03GBA424224 90R130-KA-5-DE-80-L-4-C8-F-05-GBA-35-35-24 90R130KA5DE80L4C8F05GBA353524 90-R-130-KA-5-DE-80-L-4-C8-F-05-GBA-35-35-24 90R130KA5DE80L4C8F05GBA353524 90R130-KA-5-DE-80-L-4-C8-H-00-GBA-35-35-24 90R130KA5DE80L4C8H00GBA353524 90-R-130-KA-5-DE-80-L-4-C8-H-00-GBA-35-35-24 90R130KA5DE80L4C8H00GBA353524 90R130-KA-5-DE-80-L-4-C8-H-04-GBA-42-42-24 90R130KA5DE80L4C8H04GBA424224 Constant current control: Constant flow control is another important feature of axial piston pumps to provide precise and consistent flow to hydraulic systems. This is especially useful in applications where specific flow rates are required regardless of operating conditions. Constant flow control is achieved through the use of flow control valves (also known as flow regulators or flow dividers), which are often integrated into the pump design. These valves regulate flow by controlling the displacement of the pump piston or by diverting excess flow back to the pump inlet. Flow control valves enable the operator or control system to set and maintain a specific flow rate regardless of changes in load or system pressure. It ensures that the hydraulic system receives a constant and controlled flow, which is critical for precise and consistent operation in a variety of applications. Axial piston pumps can provide stable and reliable performance in hydraulic systems, combined with pressure compensation and constant flow control mechanisms. A pressure compensation mechanism ensures that the pump can handle varying system pressures without affecting the required flow. On the other hand, a constant flow control mechanism enables precise flow regulation to meet specific application requirements. 90-R-130-KA-5-DE-80-L-4-C8-H-04-GBA-42-42-24 90R130KA5DE80L4C8H04GBA424224 90R130-KA-5-DE-80-L-4-F1-F-03-GBA-32-32-24 90R130KA5DE80L4F1F03GBA323224 90-R-130-KA-5-DE-80-L-4-F1-F-03-GBA-32-32-24 90R130KA5DE80L4F1F03GBA323224 90R130-KA-5-DE-80-P-3-C8-F-05-GBA-42-42-24 90R130KA5DE80P3C8F05GBA424224 90-R-130-KA-5-DE-80-P-3-C8-F-05-GBA-42-42-24 90R130KA5DE80P3C8F05GBA424224 90R130-KA-5-DE-80-R-3-C8-F-05-GBA-35-35-20 90R130KA5DE80R3C8F05GBA353520 90-R-130-KA-5-DE-80-R-3-C8-F-05-GBA-35-35-20 90R130KA5DE80R3C8F05GBA353520 90R130-KA-5-DE-80-R-3-C8-H-03-GBA-23-23-24 90R130KA5DE80R3C8H03GBA232324 90-R-130-KA-5-DE-80-R-3-C8-H-03-GBA-23-23-24 90R130KA5DE80R3C8H03GBA232324 90R130-KA-5-DE-80-R-3-C8-H-03-GBA-32-32-24 90R130KA5DE80R3C8H03GBA323224 90-R-130-KA-5-DE-80-R-3-C8-H-03-GBA-32-32-24 90R130KA5DE80R3C8H03GBA323224 90R130-KA-5-DE-80-R-3-C8-H-05-GBA-30-30-30 90R130KA5DE80R3C8H05GBA303030 90-R-130-KA-5-DE-80-R-3-C8-H-05-GBA-30-30-30 90R130KA5DE80R3C8H05GBA303030 90R130-KA-5-DE-80-R-3-F1-F-00-GBA-14-14-20 90R130KA5DE80R3F1F00GBA141420 90-R-130-KA-5-DE-80-R-3-F1-F-00-GBA-14-14-20 90R130KA5DE80R3F1F00GBA141420 90R130-KA-5-DE-80-R-3-F1-H-03-GBA-35-35-24 90R130KA5DE80R3F1H03GBA353524 90-R-130-KA-5-DE-80-R-3-F1-H-03-GBA-35-35-24 90R130KA5DE80R3F1H03GBA353524 90R130-KA-5-DE-80-R-4-C8-H-03-GBA-35-35-24 90R130KA5DE80R4C8H03GBA353524 90-R-130-KA-5-DE-80-R-4-C8-H-03-GBA-35-35-24 90R130KA5DE80R4C8H03GBA353524 90R130-KA-5-DE-80-R-4-F1-H-03-GBA-35-35-24 90R130KA5DE80R4F1H03GBA353524 These features make axial piston pumps ideal for applications where flow delivery and pressure stability are critical, such as industrial machinery, mobile equipment, and hydraulic systems that require precise control and operation. Here are some additional points to consider about pressure compensation and constant flow control in axial piston pumps: 1. Load sensing: Pressure compensation and constant current control can be further enhanced by load sensing technology. Load sensing allows the pump to adjust flow according to the actual load requirements of the hydraulic system. By sensing the pressure at the actuator or the highest pressure point in the system, the pump can adjust output flow to meet demand, providing optimum energy efficiency and responsiveness. 2. Proportional control: Some axial piston pumps are equipped with proportional control valves to achieve precise control of the pump output flow. These valves can be controlled electronically to adjust the angle of the pump's swash plate, allowing fine adjustments in flow. Proportional control improves flow control accuracy and flexibility for applications requiring precise and dynamic flow control. 3. Response time: To maintain the stability and efficiency of the hydraulic system, the response time of the pressure compensation and constant flow control mechanism is very important. These mechanisms should be able to respond quickly to changes in system pressure or flow demand. In hydraulic systems, fast response times help prevent pressure spikes, flow fluctuations and instabilities for stable and reliable operation. 90-R-130-KA-5-DE-80-R-4-F1-H-03-GBA-35-35-24 90R130KA5DE80R4F1H03GBA353524 90R130-KA-5-DE-80-S-3-C8-H-03-GBA-30-30-24 90R130KA5DE80S3C8H03GBA303024 90-R-130-KA-5-DE-80-S-3-C8-H-03-GBA-30-30-24 90R130KA5DE80S3C8H03GBA303024 90R130-KA-5-DE-80-S-3-C8-H-03-GBA-42-42-24 90R130KA5DE80S3C8H03GBA424224 90-R-130-KA-5-DE-80-S-3-C8-H-03-GBA-42-42-24 90R130KA5DE80S3C8H03GBA424224 90R130-KA-5-DE-80-S-3-F1-H-03-GBA-42-42-24 90R130KA5DE80S3F1H03GBA424224 90-R-130-KA-5-DE-80-S-3-F1-H-03-GBA-42-42-24 90R130KA5DE80S3F1H03GBA424224 90R130-KA-5-DE-80-S-4-C8-F-03-GBA-42-42-24 90R130KA5DE80S4C8F03GBA424224 90-R-130-KA-5-DE-80-S-4-C8-F-03-GBA-42-42-24 90R130KA5DE80S4C8F03GBA424224 90R130-KA-5-DE-80-S-4-F1-H-06-GBA-29-29-24 90R130KA5DE80S4F1H06GBA292924 90-R-130-KA-5-DE-80-S-4-F1-H-06-GBA-29-29-24 90R130KA5DE80S4F1H06GBA292924 90R130-KA-5-NN-80-D-3-C8-L-04-GBA-35-35-20 90R130KA5NN80D3C8L04GBA353520 90-R-130-KA-5-NN-80-D-3-C8-L-04-GBA-35-35-20 90R130KA5NN80D3C8L04GBA353520 90R130-KA-5-NN-80-L-3-C8-H-03-GBA-23-23-24 90R130KA5NN80L3C8H03GBA232324 90-R-130-KA-5-NN-80-L-3-C8-H-03-GBA-23-23-24 90R130KA5NN80L3C8H03GBA232324 90R130-KA-5-NN-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5NN80L3C8H03GBA292924 90-R-130-KA-5-NN-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5NN80L3C8H03GBA292924 90R130-KA-5-NN-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5NN80L3C8H03GBA353524 90-R-130-KA-5-NN-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5NN80L3C8H03GBA353524 90R130-KA-5-NN-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5NN80L3C8H03GBA424224 4. System Efficiency: Pressure compensation and constant flow control help improve overall system efficiency. By adjusting the pump output flow to meet system requirements, energy waste is minimized and the pump operates closer to its optimum efficiency point. This reduces energy consumption and increases overall system efficiency. 5. System stability: Proper pressure compensation and constant flow control help maintain system stability by preventing pressure fluctuations and flow imbalances.
