Judging and eliminating common mistakes water cooling 130w glass CO2 laser tube
1. Low power or fast speed a. Check if the current during operation does not exceed 10% of the allowable current. If the power is working for a long time, the power will drop quickly. Check whether the supporting power supply is the same specification and whether the mains voltage is normal. b. Check if the water cooling system is normal. The water cooling system mainly includes water cooling temperature, water flow rate and cooling water quality. Whether or not to open the water cooling system according to the low inlet and outlet principle. The water temperature should not exceed 30 ° C, the water flow rate is higher than 4L / min (the flow parameters are also improved according to different characteristics), the cooling water should be changed frequently, and the water cooling should be kept clean. NS. Check if the output lens, reflector lens or focus lens are dirty. Is the optical path setting correct? It is easy to contaminate the lens when dimming, and wipe with 99.7% anhydrous alcohol. D. Check if the discharge color is normal. If the color is blue or purple, or the whitish color is not normal.
2. The spot pattern is not good or changing a. Check if the water cooling system is normal. b. Is the working current too large? NS. Whether the installation direction is the same as the upward direction of the cathode end wall. D. Check whether the water cooling 130w glass CO2 laser tube support position is correct. Usually, about 1/4 of the ends are selected for water cooling 130w glass CO2 laser tube. to. Check if the lens is contaminated with foreign objects. f. Check if the discharge color is normal, the air leakage mode will also change.
3.water cooling 130w glass CO2 laser tube is dull. a. Power control line and positive and negative connections are correct. b. Check if the discharge color is normal or there is no glow discharge line. If the appearance is not damaged, the discharge color is blue or purple. Describe the air leak. If there is no high voltage discharge at the high voltage end of the glow discharge line, there is a high pressure discharge sound indicating air leakage. NS. If the glow discharge line is pale, there is no outlet at the outlet, indicating that the working gas has deteriorated. D. If there is a bright white spot on the high-voltage endpoint, or a wavy discharge line appears during the glow discharge, it can be considered a high-voltage fault, check whether the water cooling is normal, the working voltage is too high, and the supporting power supply is equipped with the corresponding specification power supply whether or not. to. If there is water inside the water cooling 130w glass CO2 laser tube, check whether the inner tube is damaged.
4, water cooling 130w glass CO2 laser tube explosion, damage a, circular arc straight slip appearance, usually occurs in the glass joint near 10 cm, this phenomenon is often caused by stress reasons. b. Often there is a sawtooth grooved type crack that appears around the cathode electrode layer and is severely fragmented and has many fragments. This phenomenon is caused by water cooling. NS. The electrode terminal or the water cooling box is damaged. The electrode terminal or water cooling box is treated with high temperature. If it is not exposed to external force, it will not be damaged. The water cooling box or the electrode column is basically not damaged, and the lens in the tube can be repaired without contamination.
5, the engraving effect is not good a, control the matching of the water cooling 130w glass CO2 laser tube and the power supply, such as the emergence or delay of the tailing phenomenon, the irregularity of the shading is mostly caused by poor matching. b. Connect or cut the thin metal wire connecting the cathode electrode column to the metal water cooling box. NS. Check if the power supply is of the corresponding type. D. Check if the engraving progress light setting parameter is correct.
6, the cutting effect is not good a, check whether the water cooling system is normal. b. Adjust the focus of the focusing mirror to be normal. NS. Adjustment of the blowing amount has reached the appropriate range. D. Replace the software with the image (circle, square) to decide whether to design the pattern.
