The scrubber has been used for a long time, and the dust in the exhaust gas or some solid particles are easily stuck in the pipe wall. In order to ensure the effectiveness of the scrubber and the efficiency of industrial waste gas treatment, the scrubber needs to be flushed regularly. Since manual flushing is inefficient, we at Longzhong can meet the demand for automatic flushing of scrubber towers.

The owner's original power system had low grid connection flexibility. In order to make it easier for factory personnel to manage the power system, Longzhong engineers transformed the system into remote control, PLC automatic calculation part and flexible PLC program control, which can provide faster and more stable power backup and shorten the time when a power outage occurs in the factory. It also shortens the power restoration time and reduces the owner’s loss costs.

VOCs, volatile organic waste gases, are inevitably produced in industrial processes. In order to comply with relevant regulations on waste gas emissions and adhere to environmentally friendly conditions, it is a very important step to detect whether VOCs are leaking.

The owner's exhaust system graphic control program has some bugs and often misjudges communication abnormalities, causing the main and backup machines to constantly switch back and forth and unable to operate normally. After Engineer Longzhong modified the graphic control program and added comprehensive logic conditions, the factory exhaust system ran smoothly, and the status of the PLC could be clearly seen on the InTouch graphic control.

Expanding water recovery requires very precise calculations. Longzhong engineers collected and transmitted back the flow sensing signals of the water pipe lines in the factory area, and used PLC to comprehensively calculate the flow values ​​in each area. In this way, the recycled water consumption of each area can be automatically calculated for factory personnel to easily check and make decisions, and it will also be easy to introduce the AI ​​automatic control system in the future.

The customer hopes to optimize the factory energy calculation process. With Longzhong's assistance, not only can he see the factory's power consumption status through the panel at any time, calculate the factory's power consumption data and production line equipment output flow, but also calculate the energy consumption of each equipment. Unit energy consumption allows owners to fully control the status of electricity usage and automatically calculate electricity bill output reports.

When the factory operator opens the bottle roller cabinet to take out the medicine, the bottle roller machine will still continue to move. This poses the risk of the personnel's fingers being entangled in the machine. It is hoped that improvement measures can be taken to address this problem. Therefore, Longzhong engineers built a device for customers to automatically control the stop of the machine to prevent fooling around.

What is GEX? It is a general exhaust, which is a very basic ventilation device. As the production line of the customer's factory gradually expands, the exhaust volume calculated by the factory at the time of the original construction is seriously insufficient and cannot meet the exhaust requirements of the clean room. The original windmill was integrated to achieve interactive operation.

To find the leak point, the factory staff have to venture into the interlayer of expansion joints in the building where there is no light at all, which is time-consuming. Longzhong assisted in optimizing the process of checking and repairing water leaks, and reversed the link map control to receive an alarm. First, he knew that there was a water leak in the expansion joint and where the leak could be located.

The industrial chemical supply system usually needs to be controlled by writing PLC programs, and cooperate with the production line to not stop, so the control part is very important. Longzhong can assist in planning a CDS protection mechanism. Even if there is a problem in the control, the chemicals can be supplied to the production line as usual in a short time without immediately affecting the production status.

The FFU in the customer's laboratory used to use power relay to control the current. When a voltage drop occurs, the power supply can be restored quickly, but the device will not automatically turn on. The owner hopes to reduce the workload of the factory staff after the power voltage drop, so that the FFU can be kept on automatically after the power is restored.

In fact, PLC needs to update the firmware regularly. Firmware update can achieve multiple benefits such as adjusting the security of the PLC system, correcting errors in the PLC code, and improving the efficiency of the firmware. Friends who want to know how to update the firmware, please don't miss this post!

PLC programmable logic controllers are often used in industrial operations, and it is not unavoidable to encounter PLC failures but do not know where the problem is. Longzhong can automatically detect errors through the PLC program, which can clearly point out which module is faulty for you, reducing a lot of debugging and testing time.

Longzhong plans the PLC control factory pure water system signal return project, which can make the monitoring of pure water quality in the factory area more timely and convenient, and it is also easier to maintain and repair. Through S7-300 PLC control, it not only allows you to manage the system conveniently, but also greatly improves the operation efficiency of the factory area.

The filter originally used in the public swimming pool of the community building was broken, and the suspended particles and hair in the swimming pool water could not be filtered out, causing the water quality to become turbid. Longzhong replaces customers with a new fully automatic circulation filter: quartz sand filter barrel....
