The great cold in the 24 solar terms is coming, which means that the weather has entered the coldest time of the year, and the temperature in some areas has dropped below zero. People should add clothes, and the laser cutting machine should also pay attention to antifreeze, so as to avoid damage to the laser cutting machine in cold winter. This laser cutting machine winter antifreeze program must be collected.
The basic principle of laser cutting machine antifreeze is to make the coolant in the laser cutting machine not reach the "freezing point". Let's list several specific methods.
Method 1: do not turn off the water cooler after the laser cutting machine does not work.
When the laser cutting machine is not working and the power supply is not cut off (power failure), the water cooler shall not be turned off. The cooling liquid is kept in a circulating flow state, and the normal temperature can be adjusted to about 10 ℃. In this way, the coolant temperature will not reach the freezing point, so the laser cutting machine will not be damaged.
Method 2: drain the coolant in the laser cutting machine
Drain the cooling liquid in each part of the equipment through the drain of the laser cutting machine. And inject pure gas to ensure that there is no coolant in the whole water circulation cooling system. This can also ensure that the laser cutting machine will not be damaged by low temperature.
Method 3: replace the coolant in the laser cutting machine
Vehicles running on the road in winter will change the antifreeze used in winter, and vehicle antifreeze can also be added to the equipment. However, the antifreeze solution of large brands must be selected, otherwise the antifreeze solution contains impurities, which will also cause damage to the equipment if it adheres to the pipes of the laser and other components. Antifreeze can not replace pure water and live ionic water for perennial use. It must be replaced in time after winter.
The above methods play an important role in whether the laser cutting machine can work normally in winter and equipment safety. The first two methods are recommended. The first method saves time and effort, but it may cause damage to the laser cutting machine in case of sudden power failure. The second method is laborious and wasteful. But it is safer and more effective than the other two methods.
In the next year, before the laser cutting machine starts to work, start the mechanical equipment, check the whole machine, check whether there are any missing oil and coolant, and timely supplement and replace them. Find out the reasons for deterioration. In order to better improve the use efficiency of the laser cutting machine.
