Common faults and troubleshooting methods in clean rooms

Cleanroom是一种需要严格控制空气Cleanliness和环境条件的特殊空间，常见于医疗、Electronics、精密制造等领域。然而，由于各种原因，Cleanroom可能会出现一些故障，影响其正常工作。以下是一些常见的Cleanroom故障及其排除方法：

1、 Common faults in clean rooms

1. The air cleanliness does not meet the standard
2. Dust accumulation or failure of high-efficiency filters
3. Uneven airflow velocity
4. Fault in the air supply system
5. Inaccurate temperature and humidity control
6. Illuminance and pressure difference control issues

2、 Exclusion method

1. The air cleanliness does not meet the standard
-Check the cleanliness of filters and ventilation ducts, and regularly clean or replace filters.
-Ensure that operations in the cleanroom are carried out according to the prescribed procedures to reduce sources of pollution.
-Check the operating status of air purification equipment to ensure its normal operation.
2. Dust accumulation or failure of high-efficiency filters
-Regularly clean the high-efficiency filter to remove accumulated dust.
-If the cleaning is ineffective, a new high-efficiency filter needs to be replaced.
-Record the usage of high-efficiency filters and develop a reasonable replacement plan.
3. Uneven airflow velocity
-Check if the layout of the air supply and return vents is reasonable, and adjust the position of the vents.
-Check for blockages or leaks in the air supply system ducts and promptly clean or repair them.
-Measure the flow velocity at each point using an anemometer and adjust it to a uniform distribution.
4. Fault in the air supply system
-Check the operating status of the air supply fan and repair or replace it promptly if there are any problems.
-Check the electrical components of the air supply system, such as switches, sensors, etc., to ensure their normal operation.
-Regularly maintain and upkeep the air supply system to ensure its long-term stable operation.
5. Inaccurate temperature and humidity control
-Check the working status of temperature and humidity sensors, and replace them promptly if there are any problems.
-Adjust the operating parameters of the air conditioning system to ensure precise control of temperature and humidity.
-Install a temperature and humidity meter in the clean room to monitor environmental parameters in real-time, and promptly identify and address any issues.
6. Illuminance and pressure difference control issues
-Check whether the brightness of the lighting equipment meets the standard and replace damaged lamps in a timely manner.
-Check the accuracy of the differential pressure sensor to ensure the precision of differential pressure control.
-Adjust the working parameters of the differential pressure controller to optimize the differential pressure control effect.
