In modern walking machinery, engineering machinery, and heavy industrial equipment, hydraulic systems are the heart that generates powerful power. As its core power source, the performance of the axial piston pump directly determines the efficiency, response speed, and reliability of the entire system. The A4VG Series 40 axial piston variable displacement pump launched by Bosch Rexroth is designed for closed circuit applications with working pressures up to 500 bar. With its extremely high power density, rich control options, and sturdy and durable structure, it has become a benchmark product in the high-end hydraulic drive field. This article will deeply analyze its technical characteristics, control principles, selection standards, and application points.
Electromagnetic compatibility: When using PWM signals to drive electromagnets, electromagnetic interference (EMI) may occur, and machine manufacturers need to take appropriate measures.
Natural frequency: During long-term operation at constant speed, it should be noted that the natural frequency of the hydraulic system may be excited by the pump's excitation frequency (speed frequency x number of plungers 9), and resonance should be avoided through reasonable pipeline design.
