In addition, at the terminal, because a large number of wires are concentrated here, secondary wires form a harness here. Therefore, in large-scale equipment, to deal with the manufacturing problems of exhaust fans and blower wire harnesses, the solutions are as follows:
(1) Draw the schematic diagram of smoke control and exhaust fan according to the standard drawing method;
(2) Automatically convert it into wiring diagram through the database of ACAD itself, VBA and related software;
(3) Send the wiring diagram to the automatic wiring harness making machine, which will make wiring harnesses according to the requirements of the drawings, and print marked numbered tubes at the ends of all wiring harnesses.

Precautions:
A, smoke control fan:
Smoke exhaust fan is an effective air purification equipment, which can make indoor air circulate, purify indoor air pollution on the one hand, and sterilize, disinfect and filter outdoor fresh air on the other hand.
When entering the room, the fresh air and fans that are cleaned every hour in the room use the patented technology of fresh air convection. Through independent air supply and wind, the indoor air is convected, and the indoor air is replaced to the greatest extent. The new multifunctional purification system with built-in fan ensures clean and healthy indoor air.
Second, the fan:
The blower sends cold air or hot air to the target through the exhaust side, so as to achieve the purpose of air circulation or heating.
(1) The hot air required for combustion is delivered to the furnace through the air preheater;
(2) drying with hot air provided by a primary fan and an air preheater, and conveying pulverized coal to a pulverizing system;
(3) The air delivered by the blower is the hot air heated at the outlet of the air preheater, and it is the hot air that enters the furnace for the second time, also known as the secondary fan.
