Explosion "Inflatable Air Blower" First check the frame, without deformation blades, blade rotation is flexible, with or without friction phenomenon. Check all fasteners are complete, tighten, there should be proof certificate number. Check motor with 500V megger insulation resistance, the resistance value if less than 50MΩ, the short-circuit current application and drying method or drying method, so that "Inflatable Air Blower" insulation resistance greater than 5 MΩ. Connect the power cable diameter should be consistent with the ring, tighten the compression nut should ensure that after the cable between the seals, no gap between the nozzle outlet, otherwise it will lose the proof performance. The assembly should ensure proof gap is less than 0.2mm, replace "Inflatable Air Blower" bearing grease, grease grades for its ZG-2H complex calcium-based Run. When installing, note flameproof surface, when the surface to be coated assembly explosion 204-1 antirust grease. All proof surface may not have damage or corrosion, or they will lose the proof performance, if any damage or corrosion phenomenon according to the "explosion-proof electrical equipment surface defect treatment provisions" repair.
