Influence of unstable air pressure on cutting effect of laser cutting machine
Air pressure on cutting effect, and it is likely to cause the cutting failure or poor cutting quality.
The unstable air pressure of the laser cutting machine will affect the cutting effect. If the air pressure is too low, the cutting debris during the cutting process will not be blown away due to the low pressure, resulting in residual slag at the incision, or cutting through. If the air pressure during the cutting process is too high, the material may shake due to the pressure. And the cutting cannot perform well.
Then, the reasons for the unstable air pressure are: after confirmation, external factors and internal factors must be subdivided. The external factors are insufficient air input from the air compressor, the laser cutting machine air regulating valve pressure regulating valve is too low, and the solenoid valve oil , The natural gas road is not smooth. If the pressure is too high, it may be caused by the failure of the air filter pressure reducing valve.
Therefore, we use the following methods to analyze and solve
First, if the input air pressure has reached the requirements, check whether the air filter pressure reducing valve is correct; the gauge pressure display can meet the cutting requirements.
Second, pay attention to the output pressure display of the air compressor before use. If it does not meet the requirements, the pressure can be adjusted or the air compressor can be overhauled.
Third, if the input air quality is poor, it will cause oil contamination in the overflow valve, the valve core is difficult to open, and the valve port cannot be fully opened.
Fourth, the pressure of the cutting torch nozzle is too low, and the pressure reducing valve needs to be replaced; the smaller the gas path section will cause low pressure, the gas pipe can be replaced according to the instructions.
Fifth, if there is no problem with the external air duct above, the internal factors of the laser cutting machine should be considered. First, check whether the air pipe is damaged, whether the air pipe is knotted, whether the joint is leaking, etc. If so, the pipe should be replaced.
Sixly, check whether the solenoid valve, one-way valve, and proportional valve in the laser cutting machine are damaged, and confirm whether the damage can be solved by replacing it in time.
The stability of the air pressure has a certain degree of influence on the cutting effect of the laser cutting machine. If the air pressure is unstable, you can follow the above methods for troubleshooting.
