In what area is the PAO laminar flow pass box pressure differential gauge placed?
In what area is the PAO laminar flow pass box pressure differential gauge placed?The laminar flow pass box is a device used to transfer items between areas of different cleanliness. It is widely used in clean workshops in the pharmaceutical, electronic, food, and other industries. It mainly forms a clean air environment inside the pass box through high-efficiency filters and laminar air supply systems to ensure that the items are not contaminated during the transfer process.The working principle is that when the items are placed in the transfer window, the door of the transfer window is closed and the laminar air supply system is started. The high-efficiency filter filters the outside air and sends it into the transfer window to form a stable laminar airflow, blowing away the dust and microorganisms on the surface of the items, thereby ensuring the cleanliness of the transfer window. At the same time, a pressure difference is usually set on both sides of the transfer window to prevent cross-contamination of air between areas of different cleanliness. So, is the pressure differential gauge of the laminar flow pass box in the general area or the clean area? Generally speaking, the pressure differential gauge is usually installed on one side of the clean area. This is because the main function of the pressure differential gauge is to monitor the pressure difference between the clean area and the non-clean area, ensuring that the pressure in the clean area is always higher than that in the non-clean area, thereby ensuring that the air flows from the clean area to the non-clean area. If the differential pressure gauge is installed on the side of the general area, it is impossible to accurately monitor the pressure in the clean area, nor can it ensure the stability of the pressure difference in the clean area. To solve this problem, we need to pay attention to the following points when installing the laminar flow pass box: First, we need to choose a suitable differential pressure gauge. The accuracy and range of the differential pressure gauge should be selected according to the use environment and requirements of the pass box to ensure that the pressure difference changes can be accurately monitored. Second, the differential pressure gauge should be installed correctly. The differential pressure gauge should be installed on the side of the clean area and should be well-sealed with the transfer window to avoid leakage. Third, the differential pressure gauge should be calibrated and maintained regularly. The differential pressure gauge may have errors during use and needs to be calibrated regularly to ensure its accuracy. At the same time, the differential pressure gauge should be maintained to keep it clean and working properly. In short, the differential pressure gauge of the laminar flow pass box is usually installed on the side of the clean area to ensure that the pressure difference between the clean area and the non-clean area can be accurately monitored. When installing and using the laminar flow pass box, we need to pay attention to selecting a suitable differential pressure gauge, correctly installing the differential pressure gauge, and regularly calibrating and maintaining the differential pressure gauge to ensure the normal operation and cleanliness requirements of the pass box. |
