In the south of China, the cold air only leaves in March every year. Although the temperature rises in April, the Qingming Festival and the valley rain are rainy. In addition to the May June rainy season, it can be said that the first half of the year is relatively humid. The rise in temperature brings about an increase in air humidity. Even the surface of walls and floor tiles can see drops of water, which is wet everywhere.
In the coming humid weather, if the moisture-proof protection of the laser cutting machine equipment is neglected under such climatic conditions, it may lead to problems such as the black screen of the console computer, the failure of the industrial computer to start, the laser alarm, the switch tripping, etc., which may affect the production. Therefore, doing a good job of moisture-proof protection of the laser cutting machine is also "escort" for the normal operation of the laser cutting machine.
Reduce indoor humidity
⑴ Active carbon is used for moisture-proof and dehumidification.
Activated carbon has many uses. It can not only dehumidify, but also purify the air and remove odor. The dehumidifier box sold in the supermarket is mainly composed of calcium fluoride and activated carbon. This is a good dehumidification product, but this dehumidification method is only applicable to small spaces, such as the control cabinet and electrical cabinet of the cutting machine, which can effectively absorb moisture and remove odor. The use of activated carbon in damp weather can reduce the environmental humidity in the control cabinet and electrical cabinet, and reduce the probability of equipment failure due to humidity.
⑵ Open the window for ventilation in fine weather.
When it is raining outside or the weather is cloudy, it is better not to open the window (especially the window facing south) to prevent hot and humid air from entering the house. When the weather is fine, you can selectively (open windows facing other directions) open windows for ventilation to reduce indoor humidity.
(3) Quicklime dehumidification.
According to the data, every 1kg of quicklime can absorb about 0.3kg of water in the air. Quicklime can absorb moisture well. If the room is wet and the ground is condensed, quicklime can also be put into cloth bags and placed at each corner of the workshop to achieve rapid dehumidification and drying.
(4) Air conditioner dehumidification.
In humid weather, the dehumidification effect of air conditioning is also very significant. Turn on the air conditioner, adjust to the dehumidification function option, and then operate the air conditioner normally. In this state, the air conditioner is equivalent to a dryer, which can reduce the indoor ambient humidity, effectively ensure that the indoor air humidity is not too high, which is very conducive to the stable operation of the equipment.
⑸ Clean the dust in the electrical cabinet regularly to achieve the purpose of dust removal and moisture removal.
Dust and dust itself are also very easy to absorb moisture in the air. Regular dedusting of the electrical cabinet can also effectively reduce the environmental humidity of the cabinet.
If there is water vapor outside the electric cabinet, do not start the machine immediately. If there is water vapor outside the electric cabinet, wipe the water vapor off the surface of the electric cabinet first. Turn on the air conditioner (dehumidification function) for half an hour, then turn on the power supply of the equipment, and observe to ensure the stable operation of the equipment.
Regular inspection
Regularly check the drainage of air compressor, filter element, cold dryer and other components. Avoid the risk of contamination of the cutting head lens and the machine tool gas pipeline due to the failure of the air compressor drainage function.
Finally, in wet weather, please pay special attention to anti-static and lightning protection. Staff must not wear slippers, and must always check whether the ground wire is grounded.
