What are the requirements for air pressure in air plasma cutting? How to match correctly?

Compared with flame cutting, NC plasma cutting machine improves cutting speed and cutting range. In addition, with the maturity and perfection of plasma cutting technology in recent years, more and more users and enterprises in the market choose plasma cutting method. Compared with traditional cutting methods, plasma cutting has the advantages of high efficiency, high precision and high stability, and is especially suitable for mass production and high precision cutting. In addition, in terms of cost, plasma cutting is more economical, especially for batch processing.

Under normal circumstances, when the working air pressure is lower than the air pressure required by the equipment, the air flow input by the air compressor is less than or equal to the specified value. At this time, the jet speed of plasma arc will be weakened, and then a plasma arc with high energy and high speed cannot be formed, resulting in poor incision quality, impenetrable incision and tumor accumulation.

From the point of view of air compressor, the main reason of insufficient air pressure is insufficient input air. In addition, the piston may be due to the low pressure adjustment of the air regulating valve of the cutting machine, oil pollution in the solenoid valve and unsmooth air passage. Wuhan Pilotage CNC advises users to accurately understand their processing requirements, including cutting materials, cutting thickness, cutting time, etc., and comprehensively purchase suitable air compressors through the above factors. When the air compressor can not meet the cutting requirements, we can clearly see from the output pressure display of the air compressor; In addition, before use, check the input air pressure, check whether the air filter pressure reducing valve is adjusted correctly, and whether the gauge pressure display can meet the cutting requirements. Otherwise, the air filter pressure reducing valve should be maintained daily to ensure that the input air is dry and free of oil pollution. (End)
