If protection is not adequate, the low temperature in winter will damage the laser tube used by the carbon dioxide laser engraving and cutting machine and cannot be recovered! So, today we will take a look at how the C02 laser cutting machine should be antifreeze treatment in winter.
The carbon dioxide laser tube is water-cooled, and the temperature is best maintained at about 25 degrees, because the energy is the strongest at this temperature.
In fact, the laser tube is very important to prevent freezing in winter and high temperature in summer. When the laser tube is not working in winter, if the water in the tube is not cleaned, the cooling layer of the laser tube will freeze and expand, and the laser cooling layer will burst, causing the laser tube to fail to work. The freezing and cracking of the laser tube cooling layer in winter are not within the scope of replacement. To avoid unnecessary losses, please do it in the correct way.
First use auxiliary equipment such as air pump or air compressor to clean the water in the laser tube. Customers who use chillers or pumps can remove the chillers or pumps and place them in a high-temperature room to prevent freezing of the water circulation equipment, causing damage to the chillers, pumps and other components, which will bring you unnecessary trouble.
Another thing to note is that do not add too much antifreeze to the laser tube, because the cooling layer of the tube will affect the quality of the light. For laser tubes, the higher the frequency, the higher the frequency of water changes. Otherwise, impurities such as calcium and magnesium in the pure water will adhere to the inner wall of the laser tube and affect the laser energy. Therefore, the most important thing is to change the water frequently and clean the water when not in use.
The chiller is also one of the keys to the antifreeze of laser equipment. In the cold winter, many users think that the water temperature will not rise too much in cold weather. So I often forget to change the water, especially in winter, because the outside temperature is very low, it is difficult to feel the spindle motor heating.
In addition, antifreeze can be used. It is generally composed of alcohol and water. It is required to have high boiling point and flash point, high specific heat and electrical conductivity, low low temperature viscosity, not easy to foam, and not corrode metal parts, hoses, etc. Add it to the matching chiller water tank. The laser equipment can prevent the cooling water from freezing, so that the chiller can start and operate normally in the cold winter.
The above is about the anti-freezing measures of CO2 laser cutting machine in winter. In order to make your laser equipment work better in winter, please master the relevant antifreeze knowledge.
