Pressure liquid level dust-free room temperature humidity monitoring mail alarm system
The factory has various pipeline pressure values, water tower liquid levels, and dust-free room temperature and humidity monitoring data that need to be monitored. Longzhong integrates system information and sets up automatic email alert notifications for customers.
Graphic Control Systems
iFIX data control clean room AHU
iFIX provides process visualization, data collection and data monitoring of production operations, enabling rapid response to production events. Through iFIX, administrators can not only clearly monitor/control the AHU air-conditioning box system of the clean room, but also set the PID value of the windmill inverter by themselves, which can be set manually or automatically output control during operation, providing user-friendly management. choose.

#Follow Longzhong to cross the sea: go! Go to Xuzhou Food Waste Fermentation Equipment Case -THE END-
In addition to the PLC point-to-point test, Longzhong also began to install sensors and field wiring and piping projects. Longzhong engineers, who strive for perfection, finally adjusted the entire fermentation system to the original plan.
Environmental Control System
#Follow Longzhong:Go!To Xuzhou part-1
We designed the food waste fermentation equipment by Longzhong himself. This system later attracted the attention of an environmental protection company in Shanghai. The other party was very interested in this. After contacting Longzhong, they made an appointment to fly to Taiwan to visit our Qingongdu Farm in Kanding, Pingtung.
PLC Design Solutions
Allen-Bradley AB PLC
The full name of "AB PLC" is "Allen-Bradley PLC", abbreviated as AB. It is a series of products made by one of the largest PLC manufacturers in the United States: Rockwell Automation.
Instrumentation control system
Oil-immersed transformer repair
In recent years, the types of home appliances have been quite diversified, and every household has purchased more and more electrical equipment. Frequent use of various types is easy to overload the oil-immersed transformer, and the overloaded transformer will heat up the inner coil and deteriorate the insulating oil.
Instrumentation control system
Siemens PLC control panel assembly
Before assembling the PLC control panel, the design is the foundation. It is necessary to design the circuit, plan the size of the panel, and customize the appropriate size of the storage control panel. After confirming that there is no problem, the subsequent assembly will be started.
Human Machine Interface
Add HMI human-machine monitoring RTO
The HMI human-machine interface can securely connect two different networks, and aggregate a large amount of data generated by the field and the central control room for the operator to manage. Long Zhong took a case that an old customer needs to add an HMI human-machine interface to monitor the RTO operation status and process.

Factory machinery and equipment utilization rate and situation room kanban
What is the utilization rate - it is a ratio that measures the usage status of the equipment from the perspective of the equipment. The simple calculation formula for the utilization rate is (operation time/load time)*100%, which is the percentage of time that the equipment is actually running
PLC Design Solutions
Clean room PLC automatic leakage detection
In a clean room, both indoor temperature and humidity must be properly controlled, and there will also be a monitoring system in the area to monitor whether the amount of dust meets the qualified standard. As the name suggests, it is a very clean place with no dust, no pollution.
PLC Design Solutions
Siemens PLC S7-400 common abnormal light check and repair
From a considerable-scale electromechanical company in Germany: Siemens SIEMENS is a PLC brand with a high usage rate on the market, so we decided to write abnormal light signals and simple repair methods. We believe that self-learning PLC and automatic control friends will help!
PLC Design Solutions
PLC programming to filter surge
In electrical engineering, spikes are transient voltage signals (voltage surges) or current signals (current surges) that are fast and short-lived in circuits.

Siemens S7 series PLC
Programmable Logic Controller,PLC,It is a digital electronic device with a microprocessor, a digital logic controller for automatic control, and can load control instructions into the memory for storage and execution at any time.
PLC Design Solutions
Mitsubishi series PLC
A programmable logic controller (PLC for short) is a digital electronic device with a microprocessor, a digital logic controller used for automatic control, which can load control commands into a memory for storage and execution at any time. What I want to introduce today is: Mitsubishi series PLC
Water Distribution System
PCW system
The process cooling water system is also known as PCW. It can not only be used to cool the machine, but also can be used as the ice water supply for the temperature control of the clean room space. It is a very common application system in the industry.
Water Distribution System
Boron wastewater resin tower
Boron is an environmental poison, a complex that exists in nature. Although the toxicity itself is not strong, it has the characteristic of accumulation, and if accumulated to a certain extent, it will cause harm to the environment. The relevant laws and regulations point out that the boron-containing wastewater cannot be discharged into the environment beyond the standard value, so it is necessary to remove the boron in the wastewater before it can be discharged.
Water Distribution System
Stripping Tower
Mass transfer effect, the ammonia nitrogen-containing wastewater is operated under alkaline conditions, the pH value is pulled to about 11, and the ammonia is separated and removed from the liquid phase by contacting with the air flow, and the ammonia can be separated into ammonia gas.
It is generally carried out in a stripping tower, and the separated gaseous ammonia is combined with sulfuric acid, combined into ammonium sulfate, and then processed and recovered by another system.
