【Abstract】 It is a key working procedure to spray catalyst symmetrically on alveolate ceramic carriers for producing motorcar exhaust converters. A control system based on "PC +PLC" is suitable for controlling a lot of spray equipments. The characters of this kind of control systemare introduced, and structure of the con- trol system based on PLC is described. The research will provide an automatic solution of high perform- ance and lowcost for factories of motorcar exhaust converters.更多还原
