Fan equipment maintenance, after the disassembly of the leaf body wheel maintenance equipment, first remove the accumulated ash and dirt on the leaf body wheel equipment, and then inspect the loss degree of the leaf body wheel in the equipment, and the friction loss and tightness of the rivet head structure. And the specific situation of welding seam welding, and pay attention to the leaf body wheel inlet and outlet sealing ring and the outer casing inlet port ring for any scratches, because the gap between the places is the smallest, if the combination is generally not in the position or During the rotating operation of the fan, due to factors such as thermal expansion, friction can be generated there. For a certain wear-through of the blade wheel, it can be repaired with iron plate. The thickness of the plate should not exceed the thickness of the blade before it is worn. The size of the plate should be able to cover the hole.
For rivet studs, if the rivet head is worn, it can be stacked and welded. If the rivet studs are loose, they should be replaced immediately. For welding seam loss or desoldering of wheels and sheets, soldering or burning is required. The micro area loss is repaired by welding, and the large area wear is burnt. Welded leaf body pieces. When welding, you should choose a welding rod with good welding performance and good toughness. For the welding of better high-manganese steel leaf blade, it is recommended that the technician use DC welding machine and knot 609. The welding weight of any piece of leaf body should be the same as the maximum amount, and the leaf body piece should be symmetrical welded to reduce the shape change and weight unevenness of the leaf body after welding.
When burning, the material and model of the deep-filled filling block should be the same as the leaf body piece. The excavation block should open the slope body mouth. When the leaf body piece is thicker, the body surface of the two sides should be opened in real time to ensure the welding quality. The quality of each piece of the excavation block is not more than 45 grams, and the weight of the tangible piece should not exceed 12 grams. After the excavation, the leaf body piece cannot be significantly deformed or distorted. The welded joints of the excavated leaf body pieces should be soft and smooth, without sand lining, moiré, and depression. The hardness of the weld should not be lower than the strength of the leaf sheet material.
