Fan troubleshooting map

Tip summary

  • The objective of this serial is to provide engineers with easy to use root cause analysis maps that can help them to easily troubleshoot the plant equipment and restore the equipment quickly to the good operating condition to save energy & cost.
  • In this video we will talk about gas moving devices trouble shooting and we will start with Fan troubleshooting.
  • For Fan the major problems root causes can be summarized in the following points:
  1. Fan noise possible root causes:
    • vortex, flow separation and we need to check the suction side conditions.
    • Loos bearing and we need to check the bearing condition and conduct required measurements.
  1. Fan Low flow rate causes:
  • Instrument error giving wrong indication and need to be checked.
  • Flow separation at suction side due to change in upstream conditions.
  • Pitch angle of blades too shallow
  • Speed slow compared to the required flow.
  • High system resistance due to required system discharge high.

3.Discharge pressure low

  • Instrument error giving wrong indication and need to be checked.
  • Fans in series rotating in the same direction
  • Operating below the stall point
  • Density increase due to change in upstream temperature.
