How to scientifically maintain of laser source in summer?

1. Ensure that the chassis is airtight


      The case of the laser source adopts a closed design, and is equipped with a case air conditioner or dehumidifier, the purpose of which is to ensure that the various components in the case are in a relatively stable and safe temperature and humidity environment. If the case is not in a closed state, the high-temperature and high-humidity air outside the case can enter the case. When it encounters internal water-cooled components, it will condense on its surface, causing possible damage. Therefore, the following aspects should be paid attention to when checking the airtightness of the chassis:

    1. Whether each cabinet door exists and is closed tightly;

    2. Whether the lifting bolts on the top are tightened;

    3. Whether the protective cover of the unused communication control interface at the rear of the chassis is covered, and whether the used ones are fixed.



2. Boot sequence


      Since the laser source chassis cannot be completely airtight, when the power is cut off at night, the chassis air conditioner stops operating. If the room is not installed with air conditioning or the night air conditioner does not work, the hot and humid external air can gradually penetrate into the chassis. Therefore, when restarting in the morning, please pay attention to the following steps:


    1. Start the laser main power supply (without light), and let the chassis air conditioner run for about 30 minutes;


    2. Start the matching chiller, wait for the water temperature to adjust to the predetermined temperature, and turn on the laser enable switch;

    3. Perform normal processing.


     Raytu recommends: If possible, under the premise of ensuring safety, the laser source should be powered off at night to keep the chassis air conditioner running. Or install the laser in an air-conditioned room, and keep the air-conditioning continuous and stable operation (including at night).


3. Water temperature setting


      The temperature of the cooling water has a direct impact on the electro-optical conversion efficiency, stability and condensation. Under normal circumstances, the cooling water temperature is set as follows:

    1. The temperature of the low-temperature water (cooling the laser module) should be set at about 21 degrees Celsius.

    2. For lasers above 2500W, the temperature of deionized DI water (cooling optics) should be set between 27 degrees and 33 degrees. This temperature should be adjusted according to the ambient temperature and humidity. Generally speaking, the higher the ambient temperature and the humidity, the higher the temperature of DI water should increase accordingly. The basic principle is that the DI water temperature should be above the dew point.


To sum up:


      Raytu reminds you that the climatic characteristics of each season are very different. The laser cutting machine is a processing equipment that requires high precision and is relatively expensive. Scientific and orderly maintenance according to the climatic characteristics can effectively avoid the minor problems of laser cutting process and improve the service life of the laser cutting machine.
