Negative Pressure Weighing Room In order to ensure a high cleanliness environment and reduce weighing errors, the following measures are usually taken:
High-efficiency filtration system: The negative pressure weighing room is equipped with high-efficiency filters, which can remove particles and pollutants in the air, such as dust, bacteria, viruses, etc. The selection and use of high-efficiency filters ensure the cleanliness of indoor air, thereby reducing errors caused by air pollution during the weighing process.
Vertical one-way airflow design: Through the unique vertical one-way airflow design, the air enters the weighing chamber from the top, flows downward evenly after being filtered, and forms a clean air layer in the work area. This design effectively prevents external contaminants from entering the work area, ensuring the accuracy and reliability of weighing operations.
Return air filtration system: After the air in the weighing room flows through the work area, it will enter the return air filtration system through the return air outlet. The return air filtration system can filter particles and pollutants in the air again to ensure the cleanliness of the circulating air. At the same time, part of the circulating air will be exhausted outside to maintain a slight negative pressure in the weighing room and prevent external pollutants from entering.
Pressure difference control: There is a pressure difference meter in the weighing room to monitor the pressure difference between indoor and outdoor. By adjusting the exhaust air volume and air supply volume, the slight negative pressure state in the weighing room can be maintained, ensuring that air always flows into the weighing room from the outside to prevent the entry of pollutants.
Regular maintenance and cleaning: In order to ensure the efficient operation and cleanliness of the Negative Pressure Weighing Room, it needs to be maintained and cleaned regularly. This includes changing filters, cleaning work areas, checking differential pressure gauges and control systems etc.
Operator training: Operators should receive professional training to understand the working principles, operating methods and safety precautions of the weighing room. They should strictly abide by operating procedures to ensure the accuracy and reliability of weighing operations.
To sum up, Negative Pressure Weighing Room can ensure a high cleanliness environment and reduce weighing through measures such as high-efficiency filtration system, vertical unidirectional air flow design, return air filtration system, pressure difference control, regular maintenance and cleaning and operator training Quantity error.
