想要了解气体增压泵在等离子切割机中的重要作用，要了解什么是等离子切割机。等离子弧切割机是利用等离子切割技术加工金属材料的机器。等离子切割是利用高温等离子弧的热量，在切割工件时熔化或部分熔化(汽化)金属部分，并借助高速等离子动量将熔化的金属去除的过程。
In order to understand the important role of gas booster pump in plasma cutting machine, we must first understand what is plasma cutting machine. Plasma arc cutting machine is a machine that uses plasma cutting technology to process metal materials. Plasma cutting is a process of using the heat of high temperature plasma arc to melt or partially melt (vaporize) the metal part when cutting the workpiece, and remove the melted metal with the help of high-speed plasma momentum.
然后，你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压缩空气作为驱动源,没有电力驱动,与升压泵的压力源、气源压力和输出压力平衡时,升压泵停止工作,通过控制驱动气源压力,然后调整输出压力。
Then, you need to understand the specific role of the gas booster pump in the plasma cutting machine. The principle of the gas booster pump is compressed air as the driving source, without electric drive. When the pressure source, pressure and output pressure of the booster pump are balanced, the booster pump stops working, and controls the driving gas source pressure through adjusting and controlling the output pressure.
当泵停止工作时，输出压力也会稳定在预先调节的压力下，当高压输出压力下降时，增压泵会自动补满压力，补充压力。通过控制气源的进气口，可以控制泵的工作频率，进而控制泵的输出流量。
When the pump stops working, the output pressure will also be stable under the pre regulated pressure. When the high-pressure output pressure drops, the booster pump will automatically fill up the pressure and supplement the pressure. By controlling the air inlet of the air source, the working frequency of the pump can be controlled, and then the output flow of the pump can be controlled.
等离子切割步骤大致分为预防-主电路供电-高频电弧切割-电弧停止。气体增压泵可将钢结构厂房内的压缩气体局部压缩到等离子切割机上，是等离子切割辅助气体的选择。气体增压泵的压力输出作为动力源通过工厂的气源，使工厂的压力加倍，避免了购买高压空气压缩机的额外成本。
Plasma cutting steps are roughly divided into prevention - main circuit power supply - high frequency arc cutting - arc stop. The gas booster pump can compress the compressed gas in the steel structure workshop to the plasma cutting machine, which is the best choice of auxiliary gas for plasma cutting. The pressure output of the gas booster pump acts as the power source to pass through the air source of the factory, doubling the pressure of the factory, avoiding the extra cost of purchasing the high-pressure air compressor.
