Since winter, the temperature has dropped sharply, and this year is a relatively cold year. We who live in South China have no impact, but the north of South China will be affected, especially the north, so the optical fiber laser cutting machine will also be affected by the low temperature. So how can we prevent the optical fiber laser cutting machine from freezing in winter?
Let's take a look here. The antifreeze principle of the optical fiber laser cutting machine is to prevent the antifreeze coolant in the machine from reaching the freezing point, so as to prevent the machine from freezing. The following methods are available for reference:
1. Do not turn off the chiller
Whether the optical fiber laser cutting machine is working or not, it is necessary to ensure that the chiller is not shut down without power failure, so that the antifreeze coolant is always in a circulating flow state. At the same time, the normal temperature of the chiller can be adjusted to about 10 ℃, so that the temperature of the antifreeze coolant can not reach the ice point, and the optical fiber laser cutting machine will not be damaged.
2. Draining antifreeze coolant
Drain the antifreeze coolant in all parts of the equipment through the water outlet of the machine, and inject pure gas at the same time to ensure that there is no antifreeze coolant in the whole water circulating cooling system. This can ensure that the optical fiber laser cutting machine will not be damaged by the low temperature in winter.
3. Replace antifreeze
When winter comes, you can buy antifreeze and add it to the machine. Select a large brand of antifreeze, which is best recommended by the manufacturer of the machine. This is guaranteed. Otherwise, there are impurities in the antifreeze, which will also cause damage to the equipment if it sticks in the pipes of laser and other components. Of course, antifreeze cannot be used as purified water all year round. After winter, when the temperature rises, it must be replaced in time.
The above methods are the effective experience of machine antifreeze obtained in practical operation, which plays an important role in the normal operation of optical fiber laser cutting machine in winter and the safety of equipment.
