The reasons for the insufficient working pressure of the plasma cutting machine are: insufficient air input to the air compressor, too low pressure adjustment of the air-conditioning valve of the CNC plasma cutting machine, oil contamination inside the solenoid valve, and the air path is not smooth. Solution: Observe the air compressor before use
Solution: Observe the output pressure display of the air compressor before use. If the requirements are not met, adjust the pressure or inspect the air compressor. If the working air pressure is far lower than the required air pressure, it means that the discharge speed of the plasma arc is weakened, and the input air flow is less than the designated value. At this time, a high-energy, high-speed plasma arc cannot be formed, resulting in poor incision quality and inability The phenomenon of tumour and incision accumulation. Conversely, if the air pressure is too high, the main reason is mainly due to improper input air conditioning, too high adjustment of the air filter pressure reducing valve, or failure of the air filter pressure reducing valve. Which manufacturer of CNC cutting machine is better? Dezhou Xi'en CNC Equipment Co., Ltd.
Otherwise, routine maintenance should be performed on the air filter pressure reducing valve to ensure that the input air is dry and free of oil. If the input air pressure exceeds 0.45MPa, the working pressure is too high. After the ion arc is formed, the excessive airflow will blow away the concentrated arc column, dispersing the energy of the arc column, and weakening the cutting strength of the plasma arc. In addition, the pressure of the cutting torch nozzle is too low, and the pressure reducing valve needs to be replaced; the smaller the cross section of the gas path will also cause the pressure to be too low, the air pipe can be replaced according to the requirements of the imitation order. If the input air pressure has reached the requirements, check whether the adjustment of the air filter pressure reducing valve is accurate; the gauge pressure display can meet the cutting requirements. If the input air quality is poor, oil pollution will occur in the pressure reducing valve, the valve core will be difficult to open, and the valve port cannot be completely opened. Too high or too low working pressure of CNC plasma cutting machine will affect the cutting effect.
