Primary air filter installation steps
Primary air filter installation stepsPrimary air filter installation steps:1. Before the installation of the new air filter, the purification room must be cleaned and scrubbed, and the air-conditioning purification system software should be cleaned and scrubbed again if there is any accumulation of dust inside the air-conditioning purification system software, and should be cleaned and scrubbed again, and it should be cleaned more than the cleaning regulations, and when the primary effect filter is installed inside the technical compartments or the decorative ceiling, it should be cleaned and scrubbed in all directions inside the technical compartments or the decorative ceiling. 2. After the clean room and air-conditioning purification system software exceeds the cleaning regulations, the air-conditioning purification system software must be run on a trial basis, and continue to run for about 12h, and then clean up again. After scrubbing the purification room, install the primary effect filter immediately. 3. Before the installation of the primary effect filter, it is necessary to dismantle the package on the installation site to carry out the external inspection, which includes the filter paper, sealant, and frame with no burrs and rust (metal material frame): there is no certificate of conformity of the product, and the technical characteristics are not by the design scheme. Subsequently, the leakage test should be carried out, and those that pass the regular leakage test should be installed first, and the installation should be based on the friction resistance size of each filter to carry out the effective formulation, for the unilateral flow, the same air outlet or the middle of each filter on the exhaust surface, the friction resistance of each rated value and the friction resistance of each average value of the distance between the two should be less than 5 percent. 4. The frame for installing the primary effect filter should be leveled, and the permissible error in the flatness of the installation frame for each primary effect filter should not exceed 1mm, and the filter should be maintained in the same orientation as the outer frame with arrows and cyclones, and the filter paper folds should be vertically divided into road surfaces when it is installed vertically. 5. The sealing in the middle of the primary effect filter and frame is generally selected from sealing gasket, rod glue, air pressure sealing, liquid tank sealing and double ring sealing, etc., be sure to scrub the surface of the filler material, the surface layer of the outer frame of the filter and the surface layer of the frame and the liquid tank, the thinness and thickness of the sealing gasket is not suitable for more than 8mm, the compression coefficient of 25% to 30%, the connection head and the material should be in line with the design programme provisions. There should be no water leakage at each interface of the frame when choosing double-ring sealing adhesive tape, it is not necessary to plug the holes on the ring cavity when adhering to the sealing, the double-ring sealing and the air pressure sealing must maintain the air pressure pipeline smooth. |
