Bolted the flameproof enclosure has two kinds of types: flat and spigot. For planar structure, not only from the bolts fastening operation, but also to ensure the plane clearance. For proof energy-saving lamps only outlet structure, when considering only the surface of the cylindrical portion explosion-proof energy-saving lamp models, tighten the bolts only play the role; when the explosion cylinder surface need to consider adding a plane, not only from the bolts fastening operations, while Since guarantee flat part of the gap effect. When tapping directly on the housing must be noted: Try not to screw fastener through the flameproof enclosure, screw 3mm above the bottom margin should be left clean-proof fluorescent light passes through the shell into a single tube, double tube, three, and emergency response, wattage 20W, 30W, 40W, suitable for use in a number of relatively large dust factories.
