A brief description of the design of the arc spraying workshop

       The arc spraying workshop is a complex operating system, generally built in a modern large-scale machining factory, and is specially designed for the arc spraying anticorrosion construction of relatively fixed products or large batches of workpieces. The arc spraying workshop includes sandblasting equipment, arc spraying equipment, painting equipment, compressed air supply system, power supply system, dust removal system, warehouse management system (including storage and management of materials, equipment, spare parts, workpieces or products, etc.), etc. With the expansion of the production scale, the level of mechanization of the arc spraying workshop is getting higher and higher, the investment amount is higher and higher, and its complexity is also higher and higher.



There are generally two modes in the arc spraying workshop: one mode is the independent partition operation mode, that is, the E major process of sandblasting, rust removal, purification and roughening, arc spraying, and post-processing is set up in sequence. Three functional operation areas, each functional area Complete a process separately without interfering with each other. The workpieces can be painted in sequence in the form of an assembly line. It is suitable for occasions where the workshop is large and the workpiece is easily transported. The advantage of this mode is that the three functional work areas can be simultaneously The work efficiency is very high; the other is a mixed operation mode, which does not have a functional work area, and the workpieces are not transferred after entering the workshop, but sandblasting, spraying and closed coating operations are performed on the workpieces in sequence, three major processes. It cannot be operated at the same time, and the construction efficiency is not high. It is suitable for occasions where the workshop is relatively small and the workpiece is particularly large. For example, the steel box girder is sprayed with anti-corrosion in the factory. One steel box girder occupies most of the workshop area. At this time, it can only be separated. To carry out the operation, first carry out sandblasting, rust removal, purification and roughening of the steel box girder entering the workshop. After the abrasives and sandblasting equipment are transferred out of the operation area, the arc spraying operation is carried out. After the arc spraying is completed, the spraying equipment is transferred away. , and then carry out the construction of the sealing coating.



The process design of the arc spraying workshop is the "leader" of the workshop engineering design. Technological design should take into account all aspects of technology and economy, law and policy. The ultimate goal is to obtain an advanced, reasonable, economical and reliable arc spray painting workshop.
