How to prolong the service life of laser tube1 laser engraving machine, cutting machine in the use of laser tube, need to pay attention to the best use of pure cooling water, and keep the water temperature below 25℃.2. Summer temperature is high, it is necessary to pay attention to frequently change the cooling water, found that the temperature is too high, need to stop and rest and replace the cooling water; Winter temperature is low, the machine after the completion of the work, need to put the laser tube internal cooling water, to avoid the laser tube is frozen cracked.3.

How to repair the failure of CO2 laser power supply?CO2 laser is widely used in laser engraving, laser cutting and other fields, mainly composed of luminescence system, motion system, control system. Next, our company will briefly introduce how to judge and troubleshoot the failure of CO2 laser power supply from the following two aspects.Laser has no laser output1. Check whether the laser tube itself is illuminated (test whether it is illuminated at the optical outlet of the laser tube). If it is illuminated normally, check whether the lens is damaged and the optical path is offset.2.

Selection and use of semiconductor laser power supplyFirst, the basic requirements of semiconductor laser power supply1. Constant current output: short-circuit constant current output, load changes or short-circuit automatic adaptation.2. Output current ripple: ripple, noise and rated output current cannot exceed the maximum current that the laser tube can bear.3. Output voltage ripple: Ripple voltage noise will not damage the laser immediately, but if serious, it will affect the life of the laser.4. Soft start: Slow start current curve, no overshoot.5.

Why the laser is weak or has no laser outputWhether the focusing mirror is contaminated: Clean the focusing mirror.Whether the focal length of relief engraving machine equipment changes: readjust the focal length.Whether the optical path is offset: Adjust the optical path carefully.Whether the reflector is contaminated or damaged: Clean or replace the reflector.Whether the laser power supply is powered on: Check the power supply loop of the laser power supply to make it normal.Whether the laser tube is damaged or aged: Replace the laser tube.Whether the laser power supply is damaged: Replace t

Technical Trends of Switching Power Supply AbroadSince the 1990s, the development of switching power supply has changed with each passing day. Many new fields and new requirements put forward newer and higher challenges to switching power supply. If we observe from the input and output window of a switching power supply, we can find that the input requirements have become more stringent, and products that do not meet the IEC1000-3-2 standard will be gradually eliminated; The output has derived many special application fields, and the difficulty of research and development has become greater.

Power supply precautions and fault detection methods of laser cutting machineLaser cutting machine power use precautionsLaser cutting machine in the process of use, to the various components of the equipment for good maintenance, to ensure the normal operation of the machine. Laser power supply is one of the most important parts in laser cutting machine equipment, improper use is easy to cause damage to the power supply, affect the normal production.

The control part of pulsed laser power supply mainly consists of signal source, signal processing and delay regulation, pulse power amplification, energy storage voltage control and other circuits. The main circuit structure of the pulsed laser power supply we developed adopts resonant switching technology, which can be closed when the current passes zero, effectively reducing the switching loss and improving the conversion efficiency.

Development of CO2 laser power supplyCO2 laser power supply accompanied with the development of CO2 laser, the initial application in the 1970s, and later with the progress of technology, the application field continues to expand.

Various techniques for switching power supplies to reduce lossesThe efficiency of PWM switching power supply without special loss control technology is lower than that of switching power supply with loss control technology. For switching power supplies that have no problem with heat dissipation, such as some off-line power supplies, the efficiency may be satisfactory. But for portable power supplies and devices requiring small size, greater efficiency must be sought.
