Duct cleaning system make the point. After processing semi-finished products should be scrubbed again into the next process, the duct should be formed immediately after cutting seams in combination, should not keep the wind pipe flange flange plane processing to ensure smooth, accurate specifications with duct match to ensure that when a combination of duct sealing connection interface. duct bottom horizontal joints shall not have, and try to avoid longitudinal seams clean purification plant, the large size of the duct should try to make the entire board, minimize ribs instrumentarija room cleaned must be located stiffeners may not use beading strengthening ribs in the duct. duct should be adopted in the production angle or corner joint seams, 6 above shall not use the clean air duct snaps style seams. seams at the zinc coating is damaged, the rivet holes and galvanized layer damaged flange weld corrosion must make do. duct flange joints and cracks around rivet holes should be coated with silicone seal. Duct flange must be smooth uniform. flange width and rivet holes, screw flange must be in strict accordance with specifications for flexible short pipe must be smooth wall, generally use leather or plastic, duct inspection door to use of soft bedding Rubber noise level of the clean room clean room decontamination, shall meet the following requirements: First, when the dynamic test, the noise level should clean room more than 70 db A. Second, the empty state tests, cleanroom turbulence noise level should not be greater than 60 db A; laminar flow clean room noise level should not exceed 65 db A. Notes: (1) due to technical and economic conditions, or greater than 70 db noise when A has no effect on the production, the noise level may be relaxed, but not more than 75 db A; (2) above the noise level means that every point in the room to work ear position (to leave) measurements. For changes in the noise, then take the same position in a normal working day equivalent continuous sound pressure level.
