Laser engraving machine is one of the more commonly used advertising equipment in our advertising industry, mainly processing a variety of non-metallic advertising plate, let us take a brief look at the laser engraving machine laser tube use precautions it.
Laser engraving machine of the use of laser tube precautions
1. cooling water recommended distilled water or pure water, we should always pay attention to the temperature of the cooling water, the water temperature should be controlled within the range of 25 ℃ -30 ℃, not too high or too low. Once the temperature of the water is too high, the cooling water should be replaced or shut down for a period of time. Cold areas cooling water shall not freeze, especially after the laser is shut down, can not make its cooling water trapped in the laser tube, in order to avoid the freezing of cooling water leads to bursting.
2. The flow rate of cooling water should be controlled at 2L~4L/min.
3. Cooling water return port in the tank must be covered by water, otherwise each time you turn on the laser tube cooling water will be filled up.
4. When in use, first connect to the cooling water, using the principle of low into high, adjust the position of the outlet pipe to ensure that the cooling water is full of cooling tube, no bubbles in the tube, and then turn on the power.
- Two support points on the laser tube 1/4 of the length of the point.
- Two support points in the laser tube 1/4 of the length of the point. 6. Laser engraving and cutting machine in the process of operation should be careful to avoid the production of smoke spattered on the surface of the output window 7. If the surface of the output window is contaminated during operation, it will lead to a drop in power, at this time we can use degreasing cotton or silk cloth dipped in anhydrous alcohol to gently wipe the outer surface of the output window 8. In the debugging process, by adjusting the laser tube support point or rotating the laser tube orientation to achieve the best output effect, and then fix the laser tube. 9. avoid the accumulation of dust near the high-voltage electrode, keep it dry, and keep the high-voltage end away from the metal to prevent high-voltage firing discharge 10. When the laser is in use, there should be no scale formation in the cooling tube to avoid blockage of cooling water and deterioration of heat dissipation. Once the scale, available 20% dilute hydrochloric acid cleaning cooling tube to remove the scale. 12. The laser tube is made of glass. In the installation, avoid local force or collision. 13. Rationalize the application of the laser tube, save laser energy, and control the operating current of the laser tube below the rated operating current.
