Application scenarios

Power industry: Control systems used in power plants can control the speed regulation valve opening of steam turbines. By outproducing a 4-20mA current signal to regulate the valve actuator, the speed of the steam turbine can be precisely controlled. It can also be used for water level control in boilers. Based on the deviation between the set water level value and the actual measured value, the module outputs an analog signal to control the opening degree of the feedwater regulating valve, maintaining a stable water level. It can also provide signals for various instruments in the power system, such as power meters and voltmeters, enabling them to accurately display relevant electrical parameters.

Petrochemical industry: In the petrochemical production process, flow control valves can be used to precisely regulate the flow of raw materials, fuels or products according to process requirements. It can also control the temperature regulating valve to adjust the flow rate of the heating or cooling medium by outproducing analog signals, achieving precise temperature control of equipment such as reaction vessels and distillation columns. It can also be used to control pressure regulating valves, maintain stable pressure in pipelines or containers, and ensure the safe and stable operation of the production process.

Water treatment industry: It can be used in sewage treatment plants to control the air flow of aeration equipment. According to the dissolved oxygen content in the sewage, the module outputs analog signals to adjust the frequency converter of the aeration fan, thereby adjusting the aeration volume to ensure the sewage treatment effect. It can also control the rotational speed of the water pump. According to the water level in the pool or the water demand, the power supply frequency of the water pump motor can be adjusted to achieve energy-saving operation and precise water level control. It can also be used to control the dosing equipment. Based on the water quality test results, the dosage of chemicals can be precisely controlled to ensure that the water quality meets the standards.

In the manufacturing industry, in the automated production lines of mechanical manufacturing, the rotational speed and torque of servo motors can be controlled. By output analog signals to servo drivers, precise control of the processing position and speed of workpieces can be achieved, thereby enhancing processing accuracy and product quality. It can also be used to control the injection pressure and speed of the injection molding machine. According to different plastic materials and product requirements, the injection molding process can be precisely adjusted to ensure the quality of product molding. It can also provide signals for various sensors and instruments on the production line, achieving real-time monitoring and control of production process parameters.

Metallurgical industry: It can be used to control the top pressure of blast furnaces. By output analog signals to adjust the opening degree of the top vent valve, the top pressure of the furnace can be kept stable to ensure the normal operation of the blast furnace. It can also control the billet pulling speed of the continuous casting machine. According to factors such as the temperature and composition of the molten steel, the rotational speed of the billet pulling motor can be precisely adjusted to ensure the quality odo bilhete fundido. Também pode ser usado para controlar a temperatura do forno de aquecimento, ajustar o fornecimento de combustível do queimador e fazer com que a temperatura dentro do forno atenda aos requisitos do processo.
