Hydraulic systems are critical components in aerospace applications, providing essential functions such as actuation, landing gear operation, and flight control. A loss of pressure in hydraulic circuits can lead to decreased performance or complete system failure. Troubleshooting hydraulic pump pressure loss requires a systematic approach to identify and rectify the underlying issues. Here are the steps to effectively troubleshoot this problem.

Start by checking the hydraulic fluid level in the reservoir. Low fluid levels can lead to insufficient suction at the pump, resulting in decreased pressure output. Ensure that the fluid is at the recommended level and that there are no leaks around the reservoir. If the fluid is low, inspect the system for leaks, as this could indicate a significant issue that needs addressing.

Next, examine the hydraulic pump itself. Inspecting the pump for visible signs of wear or damage is essential. Check for any cracks, leaks, or unusual noises that may indicate internal failure. Verify that the pump is operating within its specified speed range and that there is no blockage in the inlet line. A clogged inlet filter can restrict fluid flow, reducing pressure output. If the pump has a bypass feature, ensure that it is functioning correctly, as a malfunction here could also lead to pressure drops.
Once the pump is confirmed to be operational, evaluate the hydraulic circuit for restrictions or blockages. This includes checking hoses, fittings, and valves. Look for signs of kinking, degradation, or overheating in hoses, which can restrict fluid flow. Inspect valves for proper operation and ensure they are not partially closed or stuck, as this can significantly impact system pressure.
