1, fan vibration is too large. Cause: rotor out of balance; The foundation is not strong; The adjustment valve is closed too small to produce flying phenomenon; The bearing is damaged. Treatment method: After replacing or repairing the broken parts, redo the dynamic and static balance correction; Solid anchor bolt; Replace the bearing body; Adjust the opening of the valve.
2, insufficient air volume, wind pressure. Reason: insufficient voltage, low speed; The pipeline loss is large; Fan selection error. Treatment method: adjusting the voltage; Retrofit pipes, plug leaks, replace seals; Re-type.
3, bearing temperature rise is too high cause: too much or too little grease; There are impurities in lubricant; Rotor unbalance; Bearing load is too large; Oil station cooling water shortage. Treatment method: adjust the amount of oil and grease; There are impurities in lubricant; Rotor unbalance; Bearing load is too large; Oil station cooling water shortage. Treatment method: adjust the amount of oil and grease; Clean the tank, change the lubricant and filter, change the oil; Rebalance after replacing or repairing damaged parts; Check the waterways and regulate the amount of water.
4, the cause of motor overload: low voltage; Large air volume; Large power loss; The main axis is reversed. Treatment method: Properly close the air intake, reduce pipeline air leakage, and close the valve when starting to correct the spindle steering.
5, fan oil leakage, cause: fuel tank seal damage, treatment: repair or replace the seal.
