Common faults and solutions for medium-pressure insulation fans include but are not limited to the following:
- Excessive fan vibration: This may be caused by unbalanced rotors, loose foundations, too small adjustment valves, etc. Solutions include cleaning up dust accumulation, re-balancing, tightening anchor bolts, adjusting valve opening, etc.
- Insufficient air volume and air pressure: This may be caused by insufficient voltage, low speed, large pipeline losses, incorrect fan selection, etc. Solutions include checking voltage, adjusting speed, replacing a suitable fan, etc.
- Excessive bearing temperature rise: This may be caused by too much or too little grease, impurities in the lubricant, unbalanced rotors, excessive bearing loads, etc. Solutions include adjusting the amount of oil and grease, cleaning the oil tank and replacing lubricants and filters, replacing or repairing damaged parts and rebalancing, etc.
- Abnormal fan operation sound: This may be caused by loose fan parts, friction, etc. Solutions include tightening parts, eliminating friction, etc.
- Motor failure: This may be caused by motor overload, phase loss, short circuit, etc. Solutions include checking the motor load and the power supply line.
It should be noted that medium-pressure insulation fans of different models and manufacturers may have different fault manifestations and solutions. In the actual maintenance process, it is recommended to refer to the fan’s instruction manual and maintenance manual, or consult professional technicians to ensure that the fault is accurately diagnosed and resolved. At the same time, regular maintenance of the fan can effectively extend the fan’s service life and improve the fan’s performance and reliability.
