The outflow of defective products is greatly reduced. Quality inspection processes are arranged on the branch line and the main line, such as a step S10 on the static disc and dynamic disc supply branch line (namely, identifying good products of the static disc and good products of the dynamic disc), a step S21 on the static disc assembly branch line (namely, air tightness detection of an air pressure control element), a step S32 on the rotor and supporting disc assembly branch line (namely, identifying good products of an iron core assembly), a step S42 on the shell assembly main line (namely, hot pressing effect detection), a step 57 on the compressor assembly main line (namely, performance test) and the like.
