What are the key points for cleaning the heat dissipation system of a metal laser cutting machine?

The cleaning of the heat dissipation system of the metal laser cutting machine is a part that we must not ignore in the process of normal use. I hope everyone will not ignore it. If you don't know how to clean it before, you can take a look at the detailed introduction in the following article. Generally, you will know after reading it.

The heat dissipation system of the metal laser cutting machine is the main heat dissipation channel of the cutting torch. In the conventional configuration, it can be divided into air-cooled heat dissipation and water-cooled heat dissipation. Because the working principle of the metal laser cutting machine is to use the plasma arc column High temperature to melt the material to be cut, in general cutting processing, it is necessary to be equipped with a special air compressor as an aid to blow away the slag of the material during the cutting process to form a kerf effect.

Plasma is a special form of matter, and modern physics lists it as the fourth state of matter after solid, liquid, and gaseous states. Plasma arc is a compressed arc obtained by forced 'compression' of a free arc through mechanical compression, heat shrinkage compression and magnetic shrinkage. Its energy is concentrated, its temperature is high (arc center temperature is 18000-24000K), and its flame velocity is high (up to 300m/s or more). This article will mainly summarize and explain some of the requirements that need attention in the cleaning and daily maintenance of the metal laser cutting machine's heat dissipation system:

1. Unscrew the screws, remove the air filter, and prepare for cleaning;

2. Regularly monitor the grid voltage of the numerical control system to ensure that the fluctuation range of the grid voltage is within the allowable rated range;

3. Gently vibrate the removed filter, and at the same time, use compressed air to blow off the dust in the air filter from the inside to the outside;

4. Regularly check and replace DC motor brushes;

5. If the filter dust is too thick and the compressed air cannot be removed, it can be gently rinsed with a neutral detergent and placed in a cool place to dry;

6. Regularly replace the storage battery. Under normal circumstances, even if the battery has not failed, the battery should be replaced once a year to ensure that the system can work normally.

These are the specific cleaning methods for the heat dissipation system of the metal laser cutting machine. I believe everyone will know how to clean it after reading it.
