Water cooling is the main cooling method of metal laser cutting machine. However, if the cooling water is not properly treated, it will adversely affect the metal laser cutting machine. In summer, the cooling work of metal laser cutting machine is particularly important.
When cooling the metal laser cutting machine in summer, pay special attention to the following points:
1. It should be noted that the cooling water temperature of the metal laser cutting machine should not be too different from the air temperature. The laser and optical lens of the metal laser cutting machine are both water-cooled. Because the water in the air will condense into water when it is cold. When the cooling water temperature is lower than 5-7 ℃, there will be condensation on the surface of the metal laser cutting machine and optical lens, It has a great impact on the light output efficiency of metal laser cutting machine and the transmission of optical lens, and has a great impact on the laser energy and the service life of optical accessories. It is recommended that the majority of metal laser cutting machine users set the water temperature at 30-32 degrees, and control the temperature difference between cooling water and room temperature to be greater than 7 degrees.
2. When the temperature rises in summer, the working pressure of the cooling system of the metal laser cutting machine increases. It is recommended to check and maintain the pressure of the internal equipment of the cooling machine before the high temperature comes. The pressure of the metal laser cutting machine from different manufacturers is also different. It is recommended to consult the equipment manufacturer’s furniture parameters before maintenance.
3. Due to the high temperature in summer, the deterioration rate of cooling water will also be accelerated. It is recommended that users of metal laser cutting machines use regular distilled water or pure water, or industrial water, and regularly clean up the scale, so as not to cause the scale attached to the laser and pipe to affect the laser power. Different types of metal laser cutting machines have different methods for cleaning scale. Please operate under the guidance of the equipment manufacturer.
4. As the dust of metal laser cutting machine is mainly metal powder, it is recommended to regularly clean the dust in the gas cabinet of metal laser cutting machine and check the working condition of the cooling fan.
In summer, it is particularly important to do a good job in cooling the metal laser cutting machine. Pay attention to the above factors to avoid the failure of the metal laser cutting machine caused by improper use of cooling water.
