How to maintain the cooling system of CNC plasma cutting machine

As the main cooling channel of cutting torch, the cooling system of CNC plasma cutting machine can be divided into air-cooled cooling and water-cooled cooling in the conventional configuration. Because of the working principle of CNC plasma cutting machine, it is necessary to melt the cutting material by using the high temperature of plasma arc column in general cutting process. It is equipped with special air compressor as auxiliary to realize the cutting effect by blowing away the slag from the material in the cutting process.

Plasma is a special form of matter, which is listed in the fourth state of matter after solid, liquid and gaseous state in modern physics. Plasma arc is the free arc through mechanical compression, heat recovery compression and magnetic contraction, forced "compression" to obtain the compression arc, its energy concentration, high temperature (arc center temperature 18000-24000K), high flame velocity (up to 300 m / s).

The cleaning and routine maintenance of the numerical control plasma cutting machine need to pay attention to several aspects:

1. screw down the screws, remove the air filter of the CNC plasma cutting machine, prepare for cleaning.

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

3. Vibrate the filter lightly and blow the dust out of the air filter with compressed air.

4. regular inspection and replacement of DC motor brush;

5. If the filter dust of CNC plasma cutting machine is too thick to be removed by compressed air, neutral cleaner can be used to wash gently and put in a cool place to dry.

6. regularly replace the batteries for CNC plasma cutting machines. In general, even if the battery has not failed, it should be replaced once a year to ensure that the system can work properly.
