1. 日常保养 (Daily Maintenance)  
1.检查过滤器状态 (Check Filter Status):  
   定期检查初效过滤器（Prefilter）和高效过滤器（HEPA Filter）的堵塞情况。  
     Regularly inspect the prefilter and HEPA filter for clogging.  
   如发现压差增大或气流减弱，及时更换过滤器。  
     Replace the filters promptly if an increase in pressure difference or a decrease in airflow is detected.

2.清洁送风柜外壳 (Clean the Cabinet Exterior):  
   使用干净的软布擦拭送风柜外壳，避免灰尘积累。  
     Wipe the exterior of the cabinet with a clean, soft cloth to prevent dust accumulation.  
   避免使用腐蚀性清洁剂，以免损坏表面涂层。  
     Avoid using corrosive cleaners to prevent damage to the surface coating.

3.检查风机运行状态 (Check Fan Operation):  
   监听风机运行声音，确保无异响或振动。  
     Listen to the fan operation to ensure there is no abnormal noise or vibration.  
   定期检查风机皮带（如有）的松紧度和磨损情况。  
     Regularly check the tension and wear of the fan belt (if applicable).

4.检查电气连接 (Inspect Electrical Connections):  
   确保所有电气连接牢固，无松动或腐蚀现象。  
     Ensure all electrical connections are secure, with no looseness or corrosion.  
   定期检查控制面板和传感器的功能是否正常。  
     Regularly check the functionality of the control panel and sensors.

2. 定期维护 (Regular Maintenance)  
1.更换过滤器 (Replace Filters):  
   根据使用频率和环境条件，每36个月更换一次初效过滤器。  
     Replace the prefilter every36 months depending on usage frequency and environmental conditions.  
   每612个月更换一次高效过滤器，或根据压差指示器提示更换。  
     Replace the HEPA filter every 612 months, or as indicated by the pressure difference gauge.

2.清洁风道系统 (Clean the Air Duct System):  
   定期清理送风柜内部风道，避免积尘影响送风效果。  
     Regularly clean the internal air ducts of the cabinet to prevent dust buildup that may affect airflow.  
   使用吸尘器或压缩空气清理风道内的灰尘。  
     Use a vacuum cleaner or compressed air to remove dust from the ducts.

3.润滑风机轴承 (Lubricate Fan Bearings):  
   每6个月对风机轴承进行润滑，确保风机运行平稳。  
     Lubricate the fan bearings every 6 months to ensure smooth operation.  
   使用厂家推荐的润滑剂，避免过量润滑。  
     Use the lubricant recommended by the manufacturer and avoid overlubrication.

4.校准传感器和控制系统 (Calibrate Sensors and Control Systems):  
   定期校准风速传感器、压差传感器和温湿度传感器。  
     Regularly calibrate the airflow, pressure difference, and temperature/humidity sensors.  
   检查控制系统的参数设置，确保符合工艺要求。  
     Check the parameter settings of the control system to ensure they meet process requirements.

3. 故障排除与维修 (Troubleshooting and Repair)  
1.送风量不足 (Insufficient Airflow):  
   检查过滤器是否堵塞，必要时更换。  
     Check if the filters are clogged and replace them if necessary.  
   检查风机是否正常运行，清理风道内的障碍物。  
     Check if the fan is operating normally and remove any obstructions in the air ducts.

2.风机异响或振动 (Abnormal Fan Noise or Vibration):  
   检查风机轴承是否磨损，必要时更换。  
     Check if the fan bearings are worn and replace them if necessary.  
   检查风机叶轮是否平衡，清理叶轮上的积尘。  
     Check if the fan impeller is balanced and clean any dust buildup on the impeller.

3.控制系统故障 (Control System Malfunction):  
   检查电气连接是否正常，修复松动的接线。  
     Check if the electrical connections are normal and repair any loose wiring.  
   重启控制系统，必要时联系厂家进行软件升级或维修。  
     Restart the control system and contact the manufacturer for software updates or repairs if necessary.

4.压差异常 (Abnormal Pressure Difference):  
   检查过滤器是否安装正确，确保密封良好。  
     Check if the filters are installed correctly and ensure proper sealing.  
   检查风道系统是否有漏风现象，必要时进行密封处理。  
     Check for air leaks in the duct system and seal them if necessary.

4. 安全注意事项 (Safety Precautions)  
1.断电操作 (Power Off Before Maintenance):  
   在进行任何保养或维修操作前，务必切断电源。  
     Always disconnect the power supply before performing any maintenance or repair work.

2.佩戴防护装备 (Wear Protective Equipment):  
   更换过滤器或清理风道时，佩戴防尘口罩和手套。  
     Wear a dust mask and gloves when replacing filters or cleaning ducts.

3.遵循厂家指南 (Follow Manufacturer Guidelines):  
   严格按照设备操作手册和厂家建议进行保养与维修。  
     Strictly follow the equipment manual and manufacturer recommendations for maintenance and repairs.
