Analysis of specific measures to prevent condensation on laser cutting machines

　　 Fiber laser cutting machine is widely used in various industries, it is very common in rubber factories and ordinary factories, but in many cases improper operation, fiber laser cutting machine will appear condensation, our cutting machine manufacturers often see this situation Appears, next we mainly introduce how to avoid this situation from happening.

　　 This measure is mainly to avoid condensation of internal electronic or optical components, which can be divided into three points.

　　1. Ensure that the shell is sealed

　　 The fiber laser shell adopts a closed design and is equipped with air conditioning or dehumidification The purpose of the machine is to ensure that the components of the housing are in a relatively stable and safe temperature and humidity environment. If the box is not sealed, the high-temperature and high-humidity air outside the box may enter the box. When it encounters water-cooled internal components, it will condense on its surface and cause possible damage. Therefore, when checking whether the chassis is leaking Attention should be paid to the following aspects:

　　1. Whether each cabinet door exists and is closed correctly.

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

　　 3. Whether the protective cover of the unused communication control interface on the back of the chassis is well covered, and whether the used one is fixed.

　　Second, boot sequence

　　Because the laser cabinet cannot be completely sealed, when the power is cut off at night, the cabinet air conditioner will stop working. If the room is not equipped with air conditioner or The air conditioner does not work at night, and the hot and humid outside air will gradually infiltrate the room. Therefore, when restarting in the morning, pay attention to the following steps: 1. Turn on the main laser power (not lit) and let the cabinet air conditioner Run for about 30 minutes.

　　2, turn on the corresponding chiller, wait for the water temperature to be adjusted to the preset temperature, and the laser is turned on.

　　3. For normal processing, under the premise of ensuring safety, turn on the laser at night to keep the chassis air-conditioning working, or install the laser in the air-conditioned room to keep the air-conditioning continuous and stable operation (including night).

　　三. Water temperature adjustment

　　 The temperature of the cooling water has a direct impact on the electro-optical conversion efficiency, stability and condensation. Generally, the temperature of the cooling water The settings are as follows:

The temperature of tap water (cooling laser module) should be set at about 21 degrees Celsius. For lasers above 2500W, DI (optical cooling) deionized water temperature should be set at 27 degrees, between 33 degrees Celsius, according to the ambient temperature and Humidity adjusts the temperature. Generally speaking, the higher the ambient temperature, the higher the humidity, and the temperature of deionized water should be increased accordingly. The basic principle is that the temperature of deionized water should be higher than the dew point.

　　 Please pay attention to the above three points when operating the fiber laser cutting machine in the future to avoid condensation and reduce losses.

　　 The above is the specific measures we have told you for the condensation of fiber laser cutting machine. If you have any ideas or questions, you can contact us in time, and we will provide you with timely service.
