The accuracy and range of the hydraulically controlled two-way variable and mechanical adjustment methods of the plunger pump are limited

The two-way variables of the hydraulic control of the axial piston pump are commonly used in flow and pressure, and the compound control is a combined control based on these two variables. Flow hydraulically controlled two-way variable: When the axial piston pump is used as a hydraulic power source, its output flow is one of the most critical variables. Therefore, the flow hydraulically controlled two-way variable refers to the use of flow regulating valves and other measures to control the output flow of the axial piston pump to meet the working requirements of the hydraulic system. Pressure hydraulic control two-way variable: In some special applications, it is necessary to control the pressure generated by the hydraulic system, at this time the pressure hydraulic control two-way variable can play an important role. Through the use of devices such as pressure regulating valves, the pressure output by the axial piston pump is controlled to ensure that the hydraulic system can work stably. Compound control: In actual work, hydraulic systems often need to control two variables, flow and pressure, at the same time. At this time, a compound control method can be adopted, that is, the output flow and pressure of the axial piston pump can be controlled simultaneously through the linkage of flow regulating valve and pressure regulating valve to meet the working requirements of the hydraulic system. It should be noted that when performing hydraulic control bidirectional variable and compound control, it needs to be selected and configured according to actual application scenarios and work requirements. At the same time, it is also necessary to properly monitor and maintain the system to ensure the stability and reliability of the output variable of the axial piston pump to ensure the normal operation of the hydraulic system. In addition to flow and pressure, some other hydraulically controlled bidirectional variables are also commonly used control variables for axial piston pumps: Two-way variable speed hydraulic control: In some driving hydraulic systems, it is necessary to control the speed of the driving mechanism to meet specific work requirements. By adopting devices such as electro-hydraulic speed regulators, the speed of the axial piston pump can be controlled. 90-L-130-KA-1-BC-80-S-3-C8-F-04-GBA-38-38-28 90L130KA1BC80S3C8F04GBA383828 90L130-KA-1-BC-80-S-3-C8-F-05-GBA-45-45-30 90L130KA1BC80S3C8F05GBA454530 90-L-130-KA-1-BC-80-S-3-C8-F-05-GBA-45-45-30 90L130KA1BC80S3C8F05GBA454530 90L130-KA-1-BC-80-S-3-C8-H-03-GBA-42-42-28 90L130KA1BC80S3C8H03GBA424228 90-L-130-KA-1-BC-80-S-3-C8-H-03-GBA-42-42-28 90L130KA1BC80S3C8H03GBA424228 90L130-KA-1-BC-80-S-3-F1-F-09-GBA-26-26-24 90L130KA1BC80S3F1F09GBA262624 90-L-130-KA-1-BC-80-S-3-F1-F-09-GBA-26-26-24 90L130KA1BC80S3F1F09GBA262624 90L130-KA-1-CD-80-L-3-C8-F-03-GBA-35-35-24 90L130KA1CD80L3C8F03GBA353524 90-L-130-KA-1-CD-80-L-3-C8-F-03-GBA-35-35-24 90L130KA1CD80L3C8F03GBA353524 90L130-KA-1-CD-80-L-3-C8-H-03-GBA-35-35-20 90L130KA1CD80L3C8H03GBA353520 Two-way variable temperature hydraulic control: The hydraulic system may generate heat due to friction during work, and if it exceeds a certain temperature range, it will affect the stability and life of the system. By using temperature sensors, coolers and other devices, the temperature of the hydraulic oil output by the axial piston pump can be controlled. Position hydraulic control two-way variable: In some special applications, it is necessary to control the position of the actuator to achieve precise control results. At this time, devices such as high-precision electro-hydraulic displacement sensors can be used for position control. In practical applications, a combination of multiple hydraulic control bidirectional variables is often used to complete specific control tasks, in order to meet the system's various requirements for flow, pressure, speed, temperature, position, etc., while achieving the optimal control effect. In addition to the hydraulically controlled two-way variable, the axial piston pump can also use mechanical adjustment to adjust the output variable. Common mechanical adjustment methods include: Adjusting disc: The adjusting disc is a commonly used mechanical adjustment device. By changing the position of the adjusting disc, the output flow or pressure of the axial piston pump can be changed. The adjusting disc is usually installed on the pump body, which can be adjusted conveniently. Adjusting screw: The adjusting screw is another commonly used mechanical adjustment device. By rotating the adjusting screw, the output flow or pressure of the axial piston pump can be changed. Usually the adjusting screw is installed on the flow regulating valve or the pressure regulating valve. It should be noted that compared with the hydraulically controlled two-way variable, the precision and range of the mechanical adjustment method are limited, and cannot meet all control requirements. Therefore, in practical applications, a combination of hydraulically controlled bidirectional variable and mechanical adjustment is usually used to achieve more accurate and reliable control effects. Finally, it needs to be reminded that no matter what adjustment method is adopted, the hydraulic system needs to be properly designed and debugged to ensure the stability, reliability and safety of the system. At the same time, regular maintenance and overhaul are also required to ensure long-term stable operation of the system. In practical applications, axial piston pumps often need to be used in combination with other hydraulic components to meet various work requirements. 90-L-130-KA-1-CD-80-L-3-C8-H-03-GBA-35-35-20 90L130KA1CD80L3C8H03GBA353520 90-L-130-KA-1-CD-80-L-3-C8-H-03-GBA-38-38-24 90L130KA1CD80L3C8H03GBA383824 90-L-130-KA-1-CD-80-L-3-F1-F-03-GBA-35-35-24 90L130KA1CD80L3F1F03GBA353524 90L130-KA-1-CD-80-L-4-F1-H-03-GBA-26-26-26 90L130KA1CD80L4F1H03GBA262626 90-L-130-KA-1-CD-80-L-4-F1-H-03-GBA-26-26-26 90L130KA1CD80L4F1H03GBA262626 90-L-130-KA-1-CD-80-P-3-C8-F-03-GBA-42-42-24 90L130KA1CD80P3C8F03GBA424224 90L130-KA-1-CD-80-P-3-C8-H-03-GBA-35-35-24 90L130KA1CD80P3C8H03GBA353524 90-L-130-KA-1-CD-80-P-3-C8-H-03-GBA-35-35-24 90L130KA1CD80P3C8H03GBA353524 90L130-KA-1-CD-80-R-3-F1-F-03-GBA-38-38-24 90L130KA1CD80R3F1F03GBA383824 90-L-130-KA-1-CD-80-R-3-F1-F-03-GBA-38-38-24 90L130KA1CD80R3F1F03GBA383824 Common combinations include: Hydraulic cylinder drive system: In the hydraulic cylinder drive system, the axial piston pump is responsible for providing hydraulic energy to drive the hydraulic cylinder to complete the mechanical movement. A dual-circuit hydraulic control system is usually designed, one of which is responsible for controlling the flow or pressure, and the other is responsible for controlling the position of the hydraulic cylinder. Hydraulic motor drive system: In the hydraulic motor drive system, the axial piston pump is responsible for providing hydraulic energy to drive the hydraulic motor to complete the mechanical movement. Usually a single-loop hydraulic control system design is used to adjust the speed and torque by controlling the flow and pressure. Hydraulic servo system: In the hydraulic servo system, the axial piston pump is responsible for providing hydraulic energy and driving the hydraulic servo valve to complete the precise control of parameters such as position and speed. Devices such as high-precision electro-hydraulic proportional valves are usually used to achieve precise control of the flow and pressure output by the axial piston pump. It should be noted that in different combinations, the selection and configuration of the axial piston pump will also change. Therefore, it is necessary to select and design according to the actual application requirements, and pay attention to the matching and coordination among various hydraulic components to ensure the stable operation of the system.
