Fault Location

Identifying faults in the pump system can be challenging due to components like regulators and auxiliary pumps. Below are some steps to help locate issues:

• Checking Filters and Drain Oil: Inspect the filter for unusual quantities of impurities. A high presence of metallic particles suggests shoe failure.
• Abnormal Vibration and Sound: Identify abnormal vibrations or noises, which may indicate cavitation or pump damage.
• In Case of Two Pumps Used: Swap pipelines between pumps to determine if issues are with the pumps or downstream components.
• Measuring Pressure at Different Points: If control issues arise, measure pressures at various points instead of opening the system prematurely for accurate fault identification.
