In our previous article, we discussed the features of blowers. Now, let’s focus on how to maintain and care for them. Efficient and stable long-term operation depends heavily on proper daily maintenance. As essential ventilation equipment in industrial production, blowers are used in ventilation, dust removal, and cooling, often in complex and demanding environments. Regular inspection and maintenance not only extend the lifespan of the equipment but also reduce operational failures, enhancing work efficiency. Here is a comprehensive guide to daily blower maintenance.

1. Impeller Maintenance

The impeller is one of the core components of the blower, and its condition directly affects the fan's performance and stability. Key maintenance steps for the impeller include:

• Regularly Check Impeller Condition:
  During initial operation or frequent use, check for cracks, wear, or dust buildup on the impeller.
  If cracks or significant wear are found, stop the fan immediately to avoid further damage.

• Clean Dust from the Impeller Surface:
  Over time, dust and debris accumulate on the impeller surface, which can disrupt its dynamic balance and cause rotor vibration.
  Use a soft brush or compressed air to regularly clean the impeller, ensuring it remains free of foreign particles.

• Dynamic Balance Test:
  The balance of the impeller is crucial for stable blower operation and efficiency.
  After any impeller repair, perform a dynamic balance test. Prior to testing, ensure all bolts are tightened, as unbalanced operation can cause bolts to loosen.

2. Bearing Maintenance

Bearings are key to the blower's efficiency and lifespan. Proper bearing maintenance involves the following:

• Lubrication Check and Maintenance:
  Regularly check the lubrication oil supply to ensure sufficient lubrication, reducing friction and wear.
  If oil leakage from the bearing housing is detected, tighten the end cover bolts and check for aging or damaged seals, replacing them if necessary.

• Lubrication Oil Replacement and Replenishment:
  Depending on the operating environment and runtime, regularly replace the lubrication oil to maintain optimal lubrication. Use high-quality oil that meets standards for high temperature or heavy-duty operations.

• Proper Bearing Replacement:
  When replacing bearings, ensure both the bearings and bearing housing are clean and free of dust.
  Before installing new bearings, heat them in oil for easier installation onto the shaft. However, avoid forced installation to prevent bearing damage or reduced lifespan.

3. Motor Maintenance

The motor is the power source for the blower, and its proper operation is critical for efficient fan performance. Key motor maintenance steps include:

• Check Motor Operating Status:
  Regularly monitor motor parameters such as temperature, current, and voltage to ensure they are within normal operating ranges.
  If any anomalies are detected, such as excessive current or high temperatures, immediately stop and investigate.

• Clean Motor Surface:
  Dust accumulation on the motor surface can reduce its cooling efficiency, impacting motor life.
  Regularly clean the motor surface, especially in high-temperature environments.

• Regular Motor Winding Maintenance:
  A decrease in the motor winding’s insulation could lead to short circuits or burning.
  Periodically check the insulation performance to ensure safe motor operation.

4. Other Essential Maintenance Considerations

• Ventilation System Check:
  Ensure that the blower’s air intake and exhaust are free from obstructions to maintain smooth airflow.
  Periodically check and clean or replace the intake filter if dust buildup is found.

• Fastener Inspection:
  Over time, vibrations from blower operation can cause fasteners to loosen.
  Regularly inspect all bolts and nuts to ensure they are tightened, preventing operational issues.

• Vibration and Noise Monitoring:
  Vibration and noise levels are key indicators of the blower's condition.
  If vibration or noise suddenly increases, stop the blower immediately and check for possible causes such as impeller imbalance, bearing damage, or other mechanical failures.
