Power. Point® Presentation Chapter 14 Fluid Power System Maintenance and Troubleshooting Fluid Power System Maintenance • Fluid Power System Troubleshooting

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Hydraulic system maintenance is performed based on the results of routine inspections of equipment and systems within a specified period of time.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Mating surfaces in a hydraulic system can often have maintenance problems due to contamination and breakdown of the hydraulic fluid.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Hydraulic cylinders that are not in service must have their rods retracted to prevent contaminants from settling on any exposed metal and entering the system when the rod is moved.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Fluid stains or puddles under hydraulic equipment and hoses indicate the presence of a leak in the line.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Hydraulic hoses must be properly installed for maximum operating life.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting When preparing metal surfaces for use in fluid power systems, they should be polished with soft, nonabrasive, manufacturer-approved cleaning pads.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Pneumatic system maintenance requires regular inspection and replacement of compressed air filters.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting A hydraulic tester is used to measure the pressure, flow rate, and temperature of hydraulic fluid in a system.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting procedures are followed and documented to isolate and correct hydraulic system problems.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting The most common problem in pneumatic systems is insufficient airflow caused by leaks from worn, disconnected, or kinked hoses or tubing.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Air leaks can waste up to 25% of a pneumatic system’s energy.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting Plug-in pressure gauges can be used to trace pressure levels through a pneumatic system.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting An itemized equipment operation checklist can help an equipment operator provide information that can reduce the amount of time needed for the troubleshooting process.

Chapter 14 —Fluid Power System Maintenance and Troubleshooting electrical problems with an electrically controlled hydraulic system is performed by taking voltage or continuity readings.
