Pressure gauges and sensors are critical in monitoring hydraulic system performance. Verify that instruments are calibrated and functioning correctly. If the pressure gauge shows a false reading, it can lead to incorrect conclusions about the system’s health. Conduct a pressure test by connecting a reliable gauge directly to the pump outlet to confirm the actual pressure supplied by the pump.

If the system maintains pressure under no-load conditions but drops during operation, this indicates potential issues with system components under load. In this case, sequentially isolate and test each actuator, motor, or component in the circuit to identify any that may be restricting flow or creating excessive resistance. Look for signs of cavitation, which can occur if the pump is not receiving adequate suction pressure.

Finally, always refer to the hydraulic circuit schematic for guidance. It provides key details necessary for understanding the flow paths and components involved. This reference can help ascertain potential failure locations or provide insights into system modifications that may have occurred, which could affect performance.
In conclusion, troubleshooting hydraulic pump pressure loss in aerospace fluid circuits involves a careful examination of the entire system. By systematically checking fluid levels, the pump condition, fluid pathways, and pressure measurements, you can identify and resolve issues affecting hydraulic pressure. Maintaining proper procedures and documentation during troubleshooting is also crucial for ensuring operational integrity and safety in aerospace systems.
