Will the unstable air pressure of the laser cutting machine affect the cutting effect

  The stability of the gas pressure is an important guarantee for the cutting quality of the laser cutting machine. Some manufacturers may experience instability of the air pressure when they are in use. What causes the instability of the air pressure?
  It can be said that the unstable air pressure of the laser cutting machine will affect the cutting effect, and it will not cut through or cut badly.
  The unstable air pressure of the laser cutting machine will affect the cutting effect. If the air pressure is too low, the cutting debris will not be blown away due to the low pressure during the cutting process, resulting in residual slag at the incision, or impenetrable cutting. . And if the air pressure during cutting is too strong, the material may shake due to the air pressure, which will result in poor cutting.
  Then the reasons for the unstable air pressure are: after confirming the external factors and internal factors, we need to subdivide them. The external factors are insufficient air input from the air compressor, the pressure adjustment of the air control valve of the laser cutting machine is too low, and there is a solenoid valve. Oil pollution, air path is not smooth, etc. If the air pressure is too high, it may be due to the failure of the air filter pressure reducing valve.


  So we used the following methods to analyze and solve:
  1. If the input air pressure has reached the requirements, check whether the adjustment of the air filter pressure reducing valve is correct; the gauge pressure display can meet the cutting requirements.
  2. Pay attention to the output pressure display of the air compressor before use. If it does not meet the requirements, you can adjust the pressure or overhaul the air compressor.
  3. If the input air quality is poor, it will cause oil pollution in the pressure reducing valve, the valve core is difficult to open, and the valve port cannot be fully opened.
  4. The pressure of the cutting torch nozzle is too low, and the pressure reducing valve needs to be replaced; the reduction of the air path section will also cause the air pressure to be too low, and the air pipe can be replaced according to the instructions.
  5. If there is no problem with the above external air circuit, the internal factors of the laser cutting machine should be considered. First, check whether the air pipe is damaged, the air pipe is knotted, and the joint leaks, etc. If there is any problem, the pipe needs to be replaced.
  6. Secondly, check whether the solenoid valve, one-way valve, and proportional valve in the laser cutting machine are damaged. If the damage is confirmed, replace it in time to solve it.
  The above is the analysis and solution of the instability of the pressure of the laser cutting machine. I hope it will be helpful to you. If you have any other questions, you can directly consult our online customer service.
