How to prevent the risk of fiber laser condensation in summer
Updatetime: 2021-07-20 15:23View:
Fiber laser is the core equipment of fiber laser cutting machine, which will have a great impact on the use of the machine after failure. One of the main reasons for the failure of fiber lasers is condensation inside the laser.
In order to reduce the failure rate of fiber lasers and reduce the loss to customers due to the downtime of the fiber laser cutting machine, today we will learn what measures can effectively reduce the risk of condensation on the laser.

Water temperature setting

High and low water cooling, set the laser cooling water temperature strictly according to the factory temperature (low-temperature 23℃, high temperature: set according to the external environment)
The cooling water temperature of the laser output head is 2℃-3℃ higher than the ambient temperature.

Anti-condensation boot operation

Start the total power of the laser (the air conditioner is turned on), and the air conditioner runs for about 30 minutes.
Start the supporting water cooler, wait for the water temperature to rise to the preset temperature, and the laser emits light.
It is recommended that under the premise of ensuring safety, the laser should be powered off at night to keep the air conditioner in continuous operation or install the laser in an air-conditioned room.

Anti-condensation shutdown operation

The laser stops emitting light and turns off the light-emitting signal and the enable switch.
Turn off the water cooler after 5-10 minutes.
Turn off the air conditioner (total power) after 30 minutes.

Air conditioning maintenance

In high-temperature environments, in order to ensure that the external air conditioner works normally, clean the air conditioner filter regularly to ensure the normal operation of the equipment.

Ensure the enclosure is sealed

The case of the fiber laser 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. In order to enable the laser to start immediately, the air-conditioned room needs to be sealed to reduce air circulation inside and outside the air-conditioned room. The airtightness of the chassis needs to be checked in the following aspects:
Check whether each cabinet door exists and is closed tightly;
Whether the lifting bolts on the top are tightened;
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.
