Separated high-efficiency filter air volume and leakage detection method
Separated high-efficiency filter air volume and leakage detection methodThe high-efficiency filter with large air volume has a good role in the purification system, and can efficiently filter dust and impurities with an efficiency of up to 99.999%, based on the above features and advantages, the user is more recognized by the high-efficiency air filters, due to the high-efficiency air filters with complete specifications can be customized, widely used in industrial workshops, shopping malls, subways, airports and so on.I. High-efficiency filter influencing factors: Dust particle size: the larger, the greater the inertia, the greater the role of interception, the smaller the particle size, the more obvious diffusion. The intermediate particle size has lower filtration efficiency, so the intermediate particle size is often used to check the efficiency of the high-efficiency filter; Filtering wind speed: the larger the wind speed of the high-efficiency filter with partition, the stronger the inertia effect, but if the wind speed is too strong will be attached to the dust particles blown out, and if the wind speed is too large also makes the filtration resistance increase. The smaller the wind speed, the stronger the diffusion effect, and the smaller the filtration resistance; Fibre diameter and compactness: the finer and denser the fiber, the larger the contact area with the air, the stronger the inertia and interception effect, but the resistance increases; Attachment of dust: with the filtration, the particles deposited on the surface of the fiber gradually increase, so it is necessary to clean the filter media regularly. II. High-efficiency air filter specifications can be customized, what are the methods of installation leakage detection? The purpose of leakage testing of high-efficiency filters: the filtration efficiency of the high-efficiency filter itself is generally tested by the manufacturer, and the filter filtration efficiency report form and certificate of conformity are attached to the filter when it leaves the factory. For pharmaceutical enterprises, high-efficiency filter leakage detection refers to on-site leakage detection after the installation of high-efficiency filters and their systems, which is mainly to check the pores and other damages in the filter media, such as frame seals, gasket seals, and leakage seams on the filter frame. The purpose of leakage checking is to discover the defects in the high-efficiency filter itself and the installation promptly by checking the sealing of the high-efficiency filter and its connecting parts with the installation frame, take corresponding remedial measures to ensure the cleanliness of the area, and the installation leakage checking focuses on the sealing quality of the high-efficiency filter frame. |
