The maintenance of outdoor LED screen sheet metal cabinet is essential to ensure its long-term stable operation and prolong its service life.
The following are detailed suggestions for the maintenance of outdoor LED screen sheet metal cabinets based on the information provided in the reference article:
Cleaning work
1. Regular cleaning: Dust, stains and other impurities will accumulate on the surface of the outdoor LED screen sheet metal cabinet, which needs to be cleaned regularly.
It is recommended to use high-altitude lifting ropes or hanging rails for high-altitude work, and configure professional cleaning equipment and personnel.
2. Preparation for cleaning: Before cleaning, the main power cord needs to be unplugged to prevent electric shock. The choice of cleaning solution is also important, and you should choose a good quality cleaning solution, such as a cleaning kit that contains electrolyte, high-purity distilled water, antistatic liquid, etc.
3. Cleaning Steps:
Step 1: Vacuuming. Start by sucking up and sweeping away dirt and dust from the surface of the display mask.
Step 2: Wet cleaning. Be careful not to spray the lotion directly on the screen, but to spray a small amount of the cleaning solution on the cleaning cloth and gently wipe it in the same direction.
Step 3: Drying. Use a vacuum cleaner to blot out water marks left by wet cleaning to ensure that the display mask is clean and dust-free.
Fastening work
1. Regular inspection: Since the outdoor LED display is a high-power-consuming equipment, in the process of multiple start-stop and operation, the terminal of the power supply part may be loose, the contact is not firm or the connection is false due to thermal expansion and cold contraction.
Therefore, it is essential to regularly check the tightness of the connectors in the equipment.
2. Fastening method: When adjusting the fasteners, keep the force uniform and appropriate to ensure that the tightness is consistent.
Visual inspection
1. Visual or measurement observation: including checking whether there are damage cracks on the outer surface of the equipment, whether the angle is tilted, whether the communication and distribution cables are normal, and whether the fasteners and screws are loose and corroded.
2. Inspection of seals: For equipment with a high level of protection, it is also necessary to regularly check the integrity of its seals and the surface paint and rust of the steel structure of the outdoor screen.
Overhaul of heat dissipation and lightning protection equipment
1. Cooling equipment: Clean the cooling device, such as the fan or heat pipe, regularly to ensure that it is operating normally to enhance the heat dissipation effect.
2. Lightning protection equipment: check whether the lightning protection device is in good condition, and replace it in time if it is damaged.
Point-by-point correction
1. Runtime check: When the outdoor LED display runs for about 5000 to 10000 hours, there may be problems such as display uniformity differences, inconsistent color and brightness attenuation, etc., at this time, point-by-point correction should be considered to improve the display effect.
2. Calibration preparation: Sufficient preparations need to be made before calibration, including cleaning the LED display to remove dust and stains, replacing the defective module to ensure the display is normal, and upgrading the receiving card to support calibration.
Summary
The maintenance of outdoor LED screen sheet metal cabinet includes cleaning work, fastening work, appearance inspection, heat dissipation and lightning protection equipment overhaul, and point-by-point correction and other aspects.
Through these maintenance measures, you can ensure the normal operation of the outdoor LED screen, prolong its service life, and maintain a good display effect.
When carrying out maintenance, it should be operated in strict accordance with the relevant operating procedures to ensure safety.
