1. The fulcrum of the laser tube installation should be reasonable, and the fulcrum should be at 1/4 of the total length of the laser tube, otherwise the laser tube spot mode will deteriorate, and some work for a period of time, the spot will become several points, resulting in the decline of laser power can not meet the requirements, resulting in continuous tube replacement. Carefully read the precautions for the use of laser tubes.
2. The cooling system should be grounded, the water tank and waterway should be cleaned frequently, and the temperature control point of the refrigeration temperature control water tank should be reasonable, otherwise the laser tube is easy to be damaged, the condensation power is reduced, the cold water head of the tube falls off, the service life is greatly shortened, and sometimes it cannot work, resulting in continuous tube replacement.
3. The water protection should be checked and cleaned frequently. The cooling water often cannot be flushed. The water protection float switch or the water protection float switch does not reset, and the short-circuit method cannot be used to solve the urgent problem. The cooling water quality is good, and the aluminum oxide of the nozzle is too serious. After using it for a period of time, the dirt in the water pump, water pipe and water protection should be cleaned regularly, otherwise the laser tube will burst or the cold water head will fall off.
4. The air suction device should be checked and cleaned regularly to clean the air duct of the fan Otherwise, a lot of smoke and dust cannot be discharged, which will seriously and quickly pollute the lenses and laser tubes, making all mechanical and electronic components easy to oxidize and cause poor contact.
5. Check the focusing lens and reflector. After working for a while, the frame will heat up, and the surface of the lens will change color and rust; Film removal and cracking are the objects to be replaced, especially when many customers use large air pumps and air compressors, which will quickly accumulate water on the focusing lens. Therefore, it is necessary to check the cleanliness and quality of the optical path system of the lens (laser tube outlet) on time.
6. The working environment of the machine should not be too bad. If the ambient temperature is higher than 30 degrees and lower than 18 degrees, there is too much dust and serious air pollution, so the machine is seriously damaged and the failure rate continues to rise; Electrical accessories are easy to go wrong in humid environment. Therefore, the customer is reminded to improve the working environment and maintain the machine frequently.
7. The power of power grid should match. The power distribution and contact points of all parts of the whole equipment should be good (fans, water coolers, laser machines, laser power supplies, computers should be powered independently).
8. The working current of the laser tube should be reasonable, and it cannot work at 90-100 light intensity for a long time; To rationalize the application of laser and save laser energy; The light path system should be clean and correct, otherwise the laser tube will be prematurely aged and broken, so the working time intensity of the laser machine should be adjusted at 50-60%, and then the working speed should be adjusted according to the material. This is the best working state of the laser tube.
9. The bottom plate and the processed materials should be flat, otherwise the focal length will be inconsistent, and some places will not be cut through, so the light intensity will be increased, which will also cause the laser tube to age rapidly.
10. The heat dissipation of the laser power supply should be smooth, otherwise the temperature will rise very high once the working current is adjusted by more than 50%, which will increase the failure rate of the laser power supply. For example, TM series machines can take down the side door and directly emit the heat from the power supply.
