It is characterized by a strong adaptability to the media, smooth flow, pressure pulsation, small, high self absorption capacity, which is not a substitute for any other pump.
它的最大特点是对介质的适应性强、流量平稳、压力脉动动小、自吸能力高，这是其它任何泵种所不能替代的。
The IGV-impeller gap barely influences the compressor stage performance, but small gap leads to large pressure pulsation inside the flow field.
叶排间距大小对级性能影响几乎可以忽略，但间距减小会造成流场内压力波动增大；
