In southern China, the cold air does not leave until March every year. Although the temperature rises in April, Qingming and Guyu are rainy days. In addition, the plum rains in May and June make the first half of the year relatively humid. The rising temperature brings an increase in air humidity, and water drops can even be seen on the walls and floor tiles, which are wet everywhere. In northern China, most areas have entered the flood season in July and August, and the increase of rain has increased the humidity of the air.

In this climate, if the moisture-proof protection of the laser cutting machine equipment is neglected, it may lead to problems such as black screen of the operating table computer, failure of the industrial control computer to start, laser alarm, switch trip, etc., which will further affect production. Therefore, to do a good job in the moisture-proof protection of the laser cutting machine is also to "escort" the normal operation of the laser cutting machine.

Reduce indoor humidity

⑴ activated carbon is moisture-proof and dehumidified.

Activated carbon has many uses. It can not only dehumidify, but also purify the air and remove odor. Dehumidification boxes sold in supermarkets are 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 effectively 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 on a fine day, open the window to breathe.

When it's raining or cloudy outside, it's better not to open the window (especially the window facing south) to block the hot and humid air from entering the house. When it's sunny, you can selectively (open windows in other directions) open windows for ventilation to reduce indoor humidity.

(3) quick lime 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, the quicklime can also be placed in cloth bags at the corners of the workshop to achieve rapid moisture removal and drying.

⑷ dehumidification of air conditioner.

In wet 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 environmental humidity, effectively ensure that the indoor air humidity is not too high, and is very conducive to the stable operation of the equipment.

(5) regularly clean the dust in the electrical cabinet 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 dust removal for the electrical cabinet can also effectively reduce the environmental humidity of the cabinet.

Water vapor appears outside the electric cabinet, do not start the machine immediately

If there is water vapor on the outside of the electrical cabinet, the water vapor on the surface of the electrical cabinet should be dried first. Turn on the air conditioner (turn on the dehumidification function) for half an hour, and then turn on the power supply of the equipment for observation to ensure the stable operation of the equipment.

Regular inspection

Regularly check the drainage of air compressor, filter element, cooler and dryer and other components. Avoid the risk that the lens of the cutting head and the gas pipeline of the machine tool will be polluted due to the failure of the drainage function of the air compressor.

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.
