In winter, the laser cutting machine should also pay attention to antifreeze to avoid damage to the laser cutting equipment due to freezing in cold winter. Some measures should be taken. How to prevent laser cutting equipment from freezing in winter?
1. Do not turn off the water cooler after the laser cutting equipment does not work.
Do not turn off the water cooler when the power supply will not be cut off after not working. Keep the coolant in circulating flow state, and adjust the normal temperature to about 10 ℃. In this way, the coolant temperature cannot reach the freezing point, so the laser cutting machine will not be damaged.
2. Drain the coolant from the laser cutting equipment
Drain the coolant in all parts of the laser cutting equipment through the drain port of the laser cutting equipment. And inject pure gas to ensure that there is no coolant in the whole water circulating cooling system. This can also ensure that the laser cutting machine will not be damaged by low temperature.
3. Replace the coolant in the laser cutting equipment
The antifreeze used in winter will be replaced for cars running on the road in winter, and the vehicle antifreeze can also be added to the equipment. However, it is necessary to choose a large brand of antifreeze, otherwise the antifreeze contains impurities and will also cause damage to the equipment if it sticks in the pipes of laser and other components. Antifreeze liquid can not replace purified water and ionized water for perennial use. It must be replaced in time after winter.
