It is proved that the interference is related not only to the parameters of screw (worm) thread but also to the diameters of measuring needles selected.
论证了干涉的发生不仅与螺纹(蜗杆)的参数有关而且与选用的量针直径有关的观点。

Therefore, double screw compressor and worm compressor compared, in the same speed of the units inside less number of exhaust air ripple, big air flow noise.
因此，双螺杆压缩机与蜗杆压缩机相比，在相同转速下单位内排气次数少，气流脉动大，气流噪声大。

The world does not have never worn machine, no matter double screw compressor or worm compressor, in a few years, all needs to carry out the maintenance of the host.
