What is the reason for the large pressure fluctuations in the hydraulic system? How to stabilize the system pressure?

2025-04-28

Pressure fluctuations may be caused by the following reasons: Unstable response or improper adjustment of the axial piston pump variable mechanism7. Improper adjustment or spool jam of pressure valves (relief valves, pressure reducing valves, etc.). Air in the system, reduced elastic modulus of the oil. Actuator load changes dramatically, and the system response cannot keep up. Oil contamination causes abnormal valve movement. Ways to stabilize system pressure include: Check and adjust the pump variable mechanism to ensure smooth response. Clean or replace the problem valve to ensure flexible movement of the valve core. Completely remove air from the system and check possible air inlet locations. Install accumulators near the source of fluctuations to absorb pulsations. Improve oil cleanliness and replace filter elements regularly. For systems with drastic load changes, consider using pressure-compensated pumps or load-sensitive controls.
