Gas Booster Pump for Cutting Machine, High Pressure Booster Pump for Cutting Machine
Generally speaking, laser cutting machines use different auxiliary gases when cutting different materials. More importantly, for cutting materials with different thicknesses, the pressure and required flow rate of the auxiliary gases are different.
Practical application of gas booster pump in laser cutting carbon steel
First, when the laser cutting machine cuts carbon steel, the auxiliary gas is recommended to use oxygen with a purity of 99.5% or higher, which can achieve the purpose of combustion and blowing off the cut melt when cutting carbon steel.
Second, due to the uncertainty of the size of the cutting nozzle of different laser cutting machines and the thickness of the purchase to be cut, the pressure and flow rate of the auxiliary gas are different. Generally speaking, when the laser cutting machine cuts carbon steel, the pressure of high-purity oxygen is required to fluctuate in the range of 0.3Mpa-0.8Mpa, and the cutting nozzle fluctuates in the range of 0.02Mpa-0.05Mpa. As for the flow rate, it is more difficult to confirm. Taking cutting 22mm carbon steel as an example, it is generally required that the flow rate of high-purity oxygen needs to reach 10M3/h.
During the laser cutting process, the higher the pressure of the auxiliary gas provided by the gas booster pump, the better?
During the working process of the laser cutting machine, the auxiliary gas of the gas booster pump must reach the pressure that can completely remove the waste residue generated by cutting. When cutting thicker workpieces, the air pressure should be reduced, otherwise the residue stuck to the workpiece will damage the cutting. edge.
During the laser cutting process, the higher the pressure of the auxiliary gas provided by the gas booster pump, the better?
The pressure of the auxiliary gas of the gas booster pump is not as high as possible, but in moderation:
Indeed, increasing the pressure of the auxiliary gas can increase the cutting speed of the laser cutting machine, but it has a critical value. After reaching the critical value, increasing the gas pressure will not increase the cutting speed, but may cause the cutting speed to drop.
Why is this?
Because in the case of high-pressure auxiliary gas, the high-pressure airflow velocity not only enhances the cooling effect, but also causes intermittent shock waves in the airflow to interfere with the cooling of the laser active area.
