Antifreeze Guide Of Laser Cutting Machine
As the temperature drops significantly, the ambient temperature of the laser water cooler is too low, which may lead to the water cooler failure and pipeline icing, because the density of ice is less than the density of water, it will lead to the water cooler and the laser internal volume expansion caused by the cooling water pipeline rupture or deformation, resulting in major damage to the core components.
Basic anti-freezing measures
To avoid damage to the laser, output head, and water cooler caused by cooling liquid solidification, the following three solutions are recommended:
1. Ensure that the plant will not be powered off, do not turn off the water cooler at night, and ensure that the coolant is in a circulating state.
2. Drain the cooling liquid in the laser, laser output head and water cooler after use every day.
3. Use the antifreeze specified by the laser manufacturer as the coolant.
Cooling water emptying method
Open the drain valve of the chiller and release all the water. Remove the filter element to drain, because this part of the water can not be discharged to prevent ice will burst the shell. For some water that is not easy to discharge, it is necessary to blow off with compressed air and pay attention to the direction of incoming and outgoing water. "in" is the inlet and "out" is the outlet. It must be ventilated to the inlet.
Note: The laser, laser output head, cutting head and all the cooling water in the water cooler must be discharged clean in order to effectively protect the whole set of water cooling pipes and related devices!
Use the antifreeze specified by the laser manufacturer as the coolant
When the environment does not have the conditions to drain the coolant every day, it is necessary to add CLARIANT's Antifrogen®N antifreeze, which is added in a ratio of 3:7 (3 for antifreeze, 7 for water), and can resist -20 ° C without freezing. Clariant antifreeze official data for light yellow liquid, in case of open flame does not burn.
Note: to ensure that the water tank is clean :1, the used water is discharged, clean the inner wall of the water tank and the filter screen, add water to wash away the stain; 2, remove the filter cup, clean the cup and replace the filter element; 3, any antifreeze can not completely replace deionized water, can not be used for a long time. After winter, the pipes must be cleaned with deionized or distilled water, and use deionized or distilled water as coolant. 4, can not add antifreeze at night to keep the water tank open.
Antifreeze can only prevent icing and can not do absolute, if there are conditions, we still recommend to improve the electricity environment, keep the water cooler not shut down.
If the laser cutting machine is not used for a long time, as long as the cooling water passes through the place, especially the cooling water inside the laser and in the pipeline, it must be thoroughly cleaned.
