The sea for the C16S2R series PLC in one application design - desiccant dryer Industrial control -

My company used to buy nearly ten in1 dehumidification drying machine generally use fixed number of year is longer, most is founded at the beginning of the purchase, has more than ten years. These devices are used PCB control, after years of use, due to the electrical components ageing, maintenance factors work together, such as fault happens. Because it is old type, manufacturer has shut down, also do not provide PCB repair. And manufacturers agreed their PLC.

a part, the working principle of drying dehumidifying: returned from the dry material barrel hot and humid air after cooling, blowing into the hive wheel. The moisture in the air is wheel adsorption, and then by heating air stripping. Two air flow effect on the wheel at the same time, and with the rotation of the wheel, the moisture in the air by adsorption was recycled air continuous stripping and discharge, to form stable low air dew point, the drying temperature, heated to plastic blow into the dry material barrel, form a closed loop, dry raw materials.

part: absorption of absorb from storage VAT or other storage containers inhaled drying material barrel inside, when the vacuum hopper of reed without material are detected in the beginning, absorb the motor running, make the vacuum inside the hopper produces vacuum storage VAT of raw materials due to the pressure difference between the air drawn into a vacuum inside the hopper, when time is finished, absorption of absorb motor to stop operation, a raw material by gravity into the dry material barrel. After drying the raw material from dry barrel to install in the plastic forming machine of magic eye hopper or other inside the hopper.

2, PLC controller chooses chose sea considering the condition of PLC C16S2R, not only to simplify the circuit, but also increased the overtemperature power and fault alarm function. Figure 1

3, 1, the sea use feeling for the PLC programming software have full simulation function, reduce the scene of the programming and debugging time, convenient for the adjustment of the technical personnel, improve the working efficiency.

2, sea for PLC controller input NPN and PNP signals can be adopted, has made great use.

3, the sea has communication function of PLC, than the foreign brands of similar products cost-effective.

4, every command to open the help files, application examples. It is very practical for beginners. Has studied the PLC, the use of the sea for the PLC controller and programming software is easy to get started.

5, encryption program do well and support programs generated file encryption after the export.

all in all, I think factory is bothered to do, is worth to recommend to others. To take this opportunity to sincerely wish for PLC is doing better, as early as possible to catch up with foreign brands of PLC, also hope that more people know about the sea for PLC. You can support us to exert more power, air!
