Industrial control chassis is mainly used in harsh environments, mainly because the industrial control chassis has the characteristics of anti-vibration and corrosion resistance. It has been familiar to many technicians at present, but there are still some friends who don’t know how to choose industrial control chassis. How to buy.

method:

How to choose the material of the industrial control cabinet: The material of the high-quality industrial control cabinet is (electrolytic) galvanized steel plate, while the inferior industrial control cabinet is the steel plate of unknown origin, which is directly sprayed and installed. The high-quality industrial control cabinet has the strength to resist deformation High, good corrosion resistance, low cost, poor electrical and thermal conductivity, and corrosion resistance.

Thickness: The quality of the materials mentioned above should be good, and the thickness of the material should be paid attention to. Too thick or thin is not good. The thickness of steel plate of high-quality industrial control cabinet is generally about 1.0-1.2mm, while inferior industrial control cabinet not only uses poor materials, but also steel Very thin. Usually the thickness of the cabinet is about 0.8mm. If you want to distinguish the thickness, just lift the cabinet and look at the weight.

How to choose the handle of the industrial control case: When the accessories are installed, the weight of the industrial control case is nearly 20 kilograms. At this time, the handle of the industrial control case is very important. The handle of the high-quality industrial control case is made of high-pressure cast aluminum, which has no deformation, It has the advantages of strong load-bearing capacity and preventing the smooth metal surface from being easily removed. Inferior chassis handles will use plastic or very thin aluminum materials.

How to choose the internal structure of an industrial control case: The high-quality industrial control case has good materials and reasonable appearance design. The manufacturing process of the industrial control case also directly reflects its quality. The bottom plate tray of the high-quality case with the motherboard is processed for multiple times. Reinforcement, full crimping, structural reinforcement, front, rear, left, and right redundancy, and motherboard hole redundancy are all used. Inferior chassis, it is possible that the bottom tray and backplane are all stamped and formed at one time.

How to choose the appearance of industrial control cabinets: The appearance and structure of high-quality industrial control cabinets are carefully designed. The manufacturer will select the most reasonable, safest and most convenient one for mass production after repeated trials. The appearance of inferior cabinets is relatively It is much rougher, and most of them are imitating and copying high-quality chassis, regardless of whether they conform to the internal structure of their own chassis, causing many problems during use.

How to choose the thermal conductivity of the industrial control case: The heat dissipation of the industrial control case is very important, it determines whether the computer can work normally, too high temperature will cause the system to be unstable and accelerate the aging of the parts, the most effective case heat dissipation is currently The solution is to use an interactive heat dissipation channel structure to dissipate heat. The case fan uses a ball fan. Its advantages are large air volume, high speed, low heat generation, long life, low noise, avoid excessive noise, and truly achieve "green" heat dissipation.

How to choose the conductivity of the industrial control cabinet: Whether the material of the industrial control cabinet is conductive or not is related to the safety of the computer accessories inside the cabinet. If the purchased cabinet material is non-conductive, the static electricity that may be generated may not be conducted by the chassis bottom shell. Underground, it may cause the hard disk and board card inside the chassis to burn out; if you want to know whether it is conductive, use a meter to test. The probes are placed on both sides of the chassis board. If the indicator pins in the meter are not If it is moving, it shows that this kind of chassis is non-conductive, and it is painted directly on the steel plate.

Electromagnetic shielding of industrial control chassis: electromagnetic radiation can cause harm to the human body. When our computer host is working, the motherboard, CPU, memory and various boards will generate a large amount of electromagnetic radiation. Therefore, the chassis is required to shield electromagnetic radiation with good shielding The chassis can also effectively block external radiation interference, ensuring that the internal components of the computer are not affected by external radiation.

How to choose the shock resistance of the industrial control case: When the industrial control case is working, the optical drive, hard disk, and multiple fans in the case will vibrate when running at high speed, and the vibration can easily cause the disc read error and hard disk track Damage or even loss of data, so the earthquake resistance of the case is also a key structural design of our case. The case shock absorption system is all made of metal materials.
