CASE Instrumentation control system

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.

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....

Longzhong designed such a generator electrostatic capacitance leakage detection alarm project for customers, through the PLC control program to simulate the occurrence of liquid leakage and subsequent disconnection, and the PLC will automatically detect whether the generator is leaking or not. By sending the status back to the graphic control screen, the owner can understand the situation more quickly, and timely repair can reduce the chance of damage expansion.

In this case of the DeNOx system device piping case, the control panel visible on the graphic control is assembled to the information circuit to integrate the hardware engineering, to the subsequent piping circuit, connection to the PLC programmable logic controller, etc. It can be done for the customer, so the customer can hand over the project to Longzhong with confidence.

When installing capacitors, you need to calculate the capacitance in order to arrange the capacitors with how much capacitance to install. Longzhong is already a veteran in MEMS control. The engineer can quickly calculate the capacitance and discuss with the customer, and can also estimate how much the power factor can be improved. With clear data presentation, saving unnecessary electricity bills is no longer a problem!

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.

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.

For an industry located in an industrial zone, regular downtime is a big deal.
Whether it is a planned or unexpected power outage, we must take measures to prevent it from causing us losses.

In the process of many high-tech industries, gas has always played a very important role, especially in the semiconductor process, including: dry etching, oxidation, ion implantation, thin film deposition... and other technical processes, will use considerable much gas. The purity of gas has a decisive impact on component performance and product yield, and the safety of gas supply is related to the health of personnel and the safety of factory operations.

Clean room "junction box", also known as terminal box / storage box, storage tray, mainly provides an environment for the integration of clean room production lines and wire troughs, and at the same time achieves the functions of storage and protection. Longzhong automatic control panel started out, and has many years of design experience in the production of connecting junction boxes. The use of junction boxes in the factory to accommodate circuits can make welding and maintenance easier.
