Technical Field

The invention relates to the technical field of fans, in particular to a production process of a high-temperature smoke exhaust fan.

Background

The smoke exhaust fan is in high temperature, dense smoke and other environments for a long time, so that the temperature of a fan motor is high in the long-term use process. Therefore, the cooling and heat dissipation capacity of the fan is directly related to the service life of the fan. In addition, the surface of the fan is easy to corrode, rust and even damage in the severe environment in which the fan is used, so that the service life of the fan is further shortened, and even safety accidents can be caused.

E. spraying primer on each part;

F. assembling parts;

G. spraying antirust paint;

H. inspecting a finished product;

I. and (7) packaging and warehousing.

Further, in the step A, the material is formed by passing the material through different machine tools in batches, the cooling blade is formed by punching through a punch, the cooling front disc and the cooling rear disc are also formed by punching through the punch, the shaft sleeve is formed by metal machining through the machine tool, and then the cooling blade, the cooling front disc, the cooling rear disc and the shaft sleeve are assembled together to form the cooling impeller.

Further, in the step B, the material is firstly put into a winding drum machine to form a drum, then the two ends of the drum are closed through welding, and then a pressing flange and a pressing reinforcing rib are assembled on the drum to form the outer drum.

Furthermore, in the step C, different materials are put into a winding machine and a punch press, the winding machine enables the materials to form a cylinder, the punch press punches the materials to form guide vanes, then two ends of the cylinder are closed through welding, then a pressure applying reinforcing rib is assembled on the cylinder to form an inner cylinder, and finally a plurality of guide vanes are welded on the inner cylinder.

Furthermore, in the step D, the outer surface of the outer cylinder is firstly subjected to rib pressing through a rib pressing machine, and then the outer cylinder is bent to form a bottom foot.

And furthermore, in the step E, before the primer is sprayed, the surface of each part is subjected to rust and dirt removal, then the damaged surface is repaired and polished, and the primer is sprayed after polishing is finished.

And step F, before the parts are assembled, whether primer of the parts is dry or not is ensured, the motor is installed into the inner cylinder after the primer is dry, the cooling impeller and the motor shaft are assembled, then the inner cylinder and the outer cylinder are assembled, and finally a plurality of guide vanes on the outer wall of the inner cylinder are welded with the inner wall of the outer cylinder to form the fan.

And G, removing dirt on the outer surface of the fan, checking whether the outer surface needs to be repaired or not, polishing after the repair is finished, and spraying the anti-rust paint.

The impeller cooling device has the advantages that the impeller cooling function is realized, the outer surface of the fan is prevented from being corroded or rusted through the antirust paint, and the service life of the fan is further prolonged.
