Increasing the volume of tank can also improve the oxygen purity.
增加储气罐的体积有利于提高氧含量。
Therefore, cutting the purity of oxygen, volume, velocity, and oxygen flow shape on the gas cutting quality and cutting speed has important implications.
因此，切割氧的纯度、流量、流速和氧流形状对气割质量和切割速度有重要的影响。
Trial use of the device helps analyze such factors as pressure, temperature, and discharge that will affect the purity of the oxygen, and provides proof of improvement.
通过对装置进行试验，分析了压力、温度、流量等因素对膜分离和变压吸附制得氧气纯度的影响，为装置的进一步改进提供了依据。
