3 kw fiber laser cutting machine winter how to prevent freezing?

The basic principle of laser cutting machine anti-freezing is to make the coolant can not reach the "freezing point", there are the following methods:

Method one: do not close the water cooler after the laser cutting machine does not work.

After the laser cutting machine does not work, do not turn off the water cooler, and ensure that the power supply will not break, so that the coolant has been in a circulating flow state, and the conventional temperature can be adjusted to about 10℃. In this way, the coolant temperature does not reach freezing point, and the laser cutting machine will not be damaged.

Method two: drain the coolant in the laser cutting machine

Through the drainage port of the laser cutting machine to drain the coolant in each part of the equipment. Pure gas is injected to ensure that there is no coolant in the entire water circulation cooling system. This can also ensure that the laser cutting machine will not be harmed by low temperature.

Method three: replace the coolant in the laser cutting machine

Pure water or deionized water as coolant, once reached the freezing point will become ice expansion, resulting in damage to the machine. The antifreeze can still maintain a liquid state at lower temperatures, and a certain proportion of automotive antifreeze can also be added to the equipment. Ensure that the antifreeze does not contain impurities, otherwise sticking to the pipeline of the laser and other components will also cause damage to the equipment.

Antifreeze should not replace pure water or deionized water for perennial use. Be sure to replace in time after the winter has passed.

The methods mentioned above play a very important role in the normal work and safety of laser cutting machine in winter. The first two methods are recommended. The method saves time and effort, but it may cause damage to laser cutting machine in case of sudden power failure. Method two is laborious and wasteful. But it is safer and more effective than the other two methods.

Laser cutting machine before restarting the operation, start the mechanical equipment, check the whole machine, all kinds of oil, coolant is missing metamorphism, to fill in time to replace, metamorphism to find out the cause. To better improve the use efficiency of laser cutting machine.
