What are the uses of Shenyang Electrical Engineering ?

It is used in industrial control systems, such as how a piece of equipment operates to ensure that it can produce qualified products. Modern industry is not entirely manual and operated by humans, but is made by machines. When the machine is started, it will run by itself. The reason for automatic operation is electrical automation. The so-called electrical automation is the process of implementing sequence control and time control using electrical components such as relays and sensors. Others, such as some meters or servo motors, can feed back to the interior according to changes in the external environment, thereby changing the output and achieving stability.

Application in purification air-conditioning equipment

Control of temperature and humidity: The return air humidity installed in the ventilation pipe is similar to the temperature and humidity detected by the temperature and humidity sensor in the clean room. The ratio plus integral operation control is used to compare the sent to the controller with the set humidity. The output electric JK signal is used to control the humidity of the return air to keep it at 45%. In order to make the clean room humidity meet the GMP requirements, the action of the steam electric control valve is controlled at 65%. Temperature control: The purification air conditioning system installed in the return air pipe uses DDC to control the temperature detected by its temperature sensor and send it to the DX-9100 to output the corresponding voltage signal and compare it with the set point to control the return air temperature to 12 Control the operation of heating electric regulating valve or cold water electric regulating valve between ℃ ~ 26 ℃, so that the temperature of the clean room meets GMP requirements.

Application in the construction industry

With the rapid development of China's national economy, buildings are bound to introduce the components of electrical automation and intelligent buildings. In particular, the development of intelligent digital electronic technology has become the mainstream direction of the construction industry today. In order to save resources and manpower and achieve reasonable use of equipment, there is an automatic control system for construction equipment. There are a large number of communication automation systems in the intelligent building, including building automation systems, office automation systems, electronic equipment and wiring systems, closed-circuit television systems, fire alarm and fire linkage control systems, and security monitoring systems, as well as their corresponding wiring systems.
