The Importance of Winter Maintenance
In cold temperatures, water in the cooling system can freeze, leading to potential damage to the machine’s components. Redshiftlaser offers valuable insights and practical advice to help you safeguard your machine’s performance.
Target Audience
This article is suitable for companies, workshops, and individuals who own laser cutting machines, as well as maintenance professionals and anyone interested in laser cutting technology.
Effective Maintenance Practices
– Control the Temperature
Maintain constant operation of the water-cooling system, especially during the night, to prevent freezing.
The ideal temperature for the cooling water is between 25-30°C, but for energy efficiency, set it between 5-10°C to prevent freezing while ensuring normal water flow.
– Antifreeze Selection
Choose antifreeze with high boiling point, flash point, specific heat, and conductivity.
Select antifreeze based on local temperature conditions to prevent freezing without affecting the quality of light in the laser tube.
Regularly change the water in the laser tube, and be cautious not to use antifreeze that may harm the machine’s components.
– Drain the Cooling Water
If the laser cutting machine will be switched off for a long time, you need to evacuate the cooling water. The steps are given below.
Turn off the chillers and laser tubes, unplug the corresponding power plugs.
Disconnect the pipeline of lasers tubes and naturally drain the water into a bucket.
Pump compressed gas into one end of the pipeline (pressure shall not exceeding 0.4Mpa or 4kg), for auxiliary exhaust. After done water draining, repeat step 3 at least 2 times every 10 minutes to make sure water is completely evacuated.
Likewise, drain the water in chillers and laser heads with the instructions above.
