When the laser cooling water temperature is set below the dew point temperature, condensation is likely to occur. Condensation can cause damage to the electrical and optical components of the laser, and even cause component failure. In order to avoid condensation, the environmental conditions in which the laser is exposed must be within specific limits.
1. Working environment temperature of laser: 10 ℃ - 40 ℃;
2. Humidity of laser working environment: 10% - 80%;
3. To prevent the laser from being exposed to condensation during operation, the specific control standards are as follows:
How to prevent laser condensation:
The ambient temperature of the independent space where the laser is placed is lower than 35 ℃;
The ambient humidity in the independent space where the laser is placed is lower than 60%
It is recommended to adopt a sealed design for the equipment cabinet and install an industrial air conditioner to maintain a constant temperature and humidity state inside the cabinet, which can effectively prevent laser condensation;
4. If conditions permit, construct a separate air-conditioned room for high-power lasers, which can effectively prevent condensation of the laser in this environment;
5. When the ambient temperature and humidity are too high, there will be a dehumidification process of about 30 minutes when the laser is turned on. This is normal. Restart the laser after the dew alarm is cleared;
5. The cooling water temperature requirements for the laser QBH interface are relatively loose. A water chiller using dual temperature and dual control with Ourui laser can appropriately adjust the set water temperature to be higher than the dew point, but the set water temperature should not be higher than 30 ℃;
6. When the device is deactivated, please turn off and stop the laser and water cooler simultaneously.
What should I do if I have condensation?
What should I do if there is condensation on the laser?
1. If the laser is found to have condensation, it should be stopped immediately;
Wipe off the condensed water on the laser housing, and restart the laser after completely eliminating the condensation phenomenon;
3. Cooling and dehumidifying the environment within the required area;
Laser protection in rainy summer:
In order to avoid damage to the laser in rainstorm, please disconnect the main power supply of the laser, and pad the electric control cabinet, laser and chiller to prevent huge maintenance costs from soaking in water. In low-lying workshops, personnel should be arranged to be on duty to prevent floods and waterlogging and minimize property losses.
