等离子弧切割机是通过等离子切割技术处理金属材料的机器。等离子切割是一种加工方法，利用高温等离子弧的热量在工件切割时熔化或部分熔化(和蒸发)金属部分，并通过高速等离子体动量去除熔融金属。
Plasma arc cutting machine is a machine that processes metal materials through plasma cutting technology. Plasma cutting is a processing method, which uses the heat of high-temperature plasma arc to melt or partially melt (and evaporate) the metal part during workpiece cutting, and removes the molten metal through high-speed plasma momentum.
然后，您需要了解气体增压泵在等离子切割机上的具体作用。气体增压泵的工作原理是以压缩空气为驱动源，无需电力驱动，以增压泵为压力源，气源压力与输出压力平衡的时候，增压泵变停止工作，通过对驱动气源压力的调节，进而调节输出压力。
Then, you need to understand the specific role of gas booster pump in plasma cutting machine. The working principle of the gas booster pump is to take the compressed air as the driving source without electric drive, and take the booster pump as the pressure source. When the air source pressure is balanced with the output pressure, the booster pump will stop working, and then adjust the output pressure by adjusting the driving air source pressure.
泵停止工作时候，输出压力也会稳定在预先调节的压力上面，当高压输出端压力下降时后，增压泵会自动补压，进行压力补充。通过控制气源的进气量，可以控制泵的工作频率，进而控制泵的输出流量，具有操作简单，可靠等特点。
When the pump stops working, the output pressure will also stabilize above the pre regulated pressure. When the pressure at the high-pressure output end decreases, the booster pump will automatically supplement the pressure for pressure supplement. By controlling the air intake of the air source, the working frequency of the pump can be controlled, and then the output flow of the pump can be controlled. It has the characteristics of simple operation, safety and reliability.
等离子切割步骤大致为预通风 - 主回路电源 - 高频电弧 - 切割过程 - 电弧停止。气体增压泵可以将钢构厂内的压缩气体局部压缩到等离子切割机，这是等离子切割辅助气体的选择。气体增压泵的压力输出用作通过工厂气源的驱动源，这可以使工厂内的压力加倍并且避免购买高压空气压缩机的额外成本。
Plasma cutting steps are roughly pre ventilation - main circuit power supply - high frequency arc - cutting process - arc stop. The gas booster pump can locally compress the compressed gas in the steel structure plant to the plasma cutting machine, which is the choice of auxiliary gas for plasma cutting. The pressure output of the gas booster pump is used as the driving source through the plant air source, which can double the pressure in the plant and avoid the additional cost of purchasing high-pressure air compressor.
