Axial piston pumps can be classified into different control types based on their ability to provide constant pressure or constant flow. The following describes the constant pressure control and constant flow control of the axial piston pump: Constant pressure control: Axial piston pumps with constant pressure control are designed to maintain a consistent pressure in a hydraulic system regardless of changing loads. These pumps are typically used in applications where maintaining a specific pressure level is critical, such as hydraulic presses, machine tools or hydraulic systems requiring precise force control. Constant pressure control is achieved by using a pressure compensator or pressure control valve within the pump. These mechanisms monitor system pressure and adjust pump displacement or delivery to meet demand and maintain desired pressure levels. As the load increases or decreases, the pump automatically adjusts its output to ensure a constant pressure. Constant flow control: Axial piston pumps with constant flow control are designed to provide consistent flow regardless of changes in system pressure. These pumps are typically used in applications requiring specific flow rates, such as conveying systems, fan drives or hydraulic motors. Constant flow control is usually achieved through the use of flow control valves or flow compensators within the pump. These mechanisms regulate the displacement or delivery of the pump to maintain a constant flow despite changes in system pressure. As system pressure changes, the pump adjusts its output to compensate and provide a consistent flow. It is important to note that some axial piston pumps offer both constant pressure and constant flow control, allowing for versatility and adaptability in a variety of applications. These pumps may incorporate additional control features such as load sensing systems or electrohydraulic controls to optimize performance and efficiency. The exact method and mechanism used for constant pressure or constant flow control may vary by axial piston pump design and manufacturer. It is therefore recommended to refer to the pump's technical documentation or consult the manufacturer for details on the control functions and operating characteristics of a particular pump model. 90-R-130-KP-1-CD-80-P-4-F1-H-03-GBA-29-38-24 90R130KP1CD80P4F1H03GBA293824 90-R-130-KP-1-CD-80-P-3-F1-F-03-GBA-35-35-20 90R130KP1CD80P3F1F03GBA353520 90R130-KP-1-CD-80-P-3-F1-F-03-GBA-35-35-20 90R130KP1CD80P3F1F03GBA353520 90-R-130-KP-1-CD-80-P-3-F1-F-03-GBA-20-20-20 90R130KP1CD80P3F1F03GBA202020 90R130-KP-1-CD-80-P-3-F1-F-03-GBA-20-20-20 90R130KP1CD80P3F1F03GBA202020 90-R-130-KP-1-CD-80-P-3-F1-F-00-GBA-38-38-20 90R130KP1CD80P3F1F00GBA383820 90R130-KP-1-CD-80-P-3-F1-F-00-GBA-38-38-20 90R130KP1CD80P3F1F00GBA383820 90-R-130-KP-1-CD-80-L-4-F1-F-03-GBA-35-35-24 90R130KP1CD80L4F1F03GBA353524 90R130-KP-1-CD-80-L-4-F1-F-03-GBA-35-35-24 90R130KP1CD80L4F1F03GBA353524 90-R-130-KP-1-CD-80-L-3-F1-H-03-GBA-32-32-24 90R130KP1CD80L3F1H03GBA323224 certainly! Here are some additional details about constant pressure control and constant flow control for axial piston pumps: Constant pressure control: The pressure compensator or pressure control valve in the constant pressure control axial piston pump adjusts the displacement or delivery of the pump according to the change of the system pressure. If the system pressure exceeds the desired set pressure, the pressure compensator reduces the displacement of the pump, thereby reducing the flow and maintaining a constant pressure. Conversely, if the system pressure is lower than the desired set pressure, the pressure compensator increases the displacement of the pump, increasing the flow to maintain a constant pressure. Constant pressure control is beneficial in applications where maintaining a specific pressure level is critical for consistent performance and safety. Constant flow control: Constant Flow Control A flow control valve or flow compensator in an axial piston pump adjusts the displacement or delivery of the pump to maintain a constant flow. As system pressure increases, the flow control valve reduces the displacement of the pump, compensating for the increased resistance and maintaining a consistent flow. Likewise, if the system pressure decreases, the flow control valve increases the displacement of the pump to compensate and provide a constant flow. Constant flow control is especially useful in applications that require a specific flow to precisely control a hydraulic actuator or maintain a consistent speed of a hydraulic motor. It is worth noting that the constant pressure and constant flow control is realized through the hydraulic components and control mechanism inside the axial piston pump itself. However, the design and configuration of the entire hydraulic system, including additional valves, sensors, and controls, also plays a critical role in achieving and maintaining the desired pressure or flow conditions. Additionally, some axial piston pumps may offer variable control options that allow the operator to switch between constant pressure and constant flow control modes to meet the specific requirements of the application. This flexibility provides adaptability to different operating conditions and enhances the versatility of the axial piston pump. Constant pressure control: Constant pressure control in axial piston pumps is essential in applications where maintaining a specific pressure level is critical to the proper functioning or safety of a hydraulic system. A pressure compensator or pressure control valve is usually part of the pump control system and continuously monitors the system pressure. When the system pressure exceeds the desired set pressure, the pressure compensator adjusts the displacement or delivery of the pump to reduce the flow and maintain a constant pressure. This control mechanism ensures that system pressure remains stable even as load demands vary, providing consistent performance and preventing damage to system components. 90R130-KP-1-CD-80-L-3-F1-H-03-GBA-32-32-24 90R130KP1CD80L3F1H03GBA323224 90-R-130-KP-1-BC-80-S-3-F1-F-03-GBA-42-42-24 90R130KP1BC80S3F1F03GBA424224 90-R-130-KP-1-BC-80-P-3-F1-H-03-GBA-38-38-24 90R130KP1BC80P3F1H03GBA383824 90-R-130-KP-1-BC-80-P-3-F1-F-03-GBA-38-38-20 90R130KP1BC80P3F1F03GBA383820 90-R-130-KP-1-BC-80-L-3-F1-F-03-GBA-35-35-24 90R130KP1BC80L3F1F03GBA353524 90-R-130-KP-1-AB-80-S-4-C8-F-03-GBA-35-35-24 90R130KP1AB80S4C8F03GBA353524 90R130-KP-1-AB-80-S-4-C8-F-03-GBA-35-35-24 90R130KP1AB80S4C8F03GBA353524 90-R-130-KP-1-AB-80-R-3-F1-H-03-GBA-42-42-24 90R130KP1AB80R3F1H03GBA424224 90-R-130-KP-1-AB-80-P-3-F1-F-00-GBA-42-42-24 90R130KP1AB80P3F1F00GBA424224 90R130-KP-1-AB-80-P-3-F1-F-00-GBA-42-42-24 90R130KP1AB80P3F1F00GBA424224 Constant flow control: Constant flow control in axial piston pumps is important in applications that require a specific flow for precise control or consistent performance. Flow control valves or flow compensators are integrated into the pump design and function by regulating the displacement or delivery of the pump. If the system pressure increases, the flow control valve will reduce the displacement of the pump to compensate for the increase in resistance, thereby maintaining a constant flow. Conversely, when system pressure decreases, the flow control valve increases the displacement of the pump to ensure a consistent flow. Constant flow control allows precise control of hydraulic actuators or consistent speed regulation of hydraulic motors, contributing to efficient and reliable system operation. It is important to note that the specific design and control mechanism used for constant pressure control and constant flow control may vary from one axial piston pump to another. Therefore, it is critical to refer to the pump's technical documentation or consult the manufacturer for precise control functions, adjustment methods and operating considerations for a particular axial piston pump model. Additionally, it is important to properly configure and calibrate the control system in conjunction with the axial piston pump to achieve accurate and reliable control of pressure or flow. This may involve setting appropriate pressure or flow set points, adjusting control valves, and ensuring proper integration throughout the hydraulic system.
