Who is better, the twin screw compressor or the single screw compressor?
双螺杆与单螺杆压缩机，谁更好一点？
Single screw compressor is a new compressor after piston type compressor.
单螺杆压缩机是继活塞式压缩机之后的新一代压缩机。
At the same time, because of double screw compressor stress is bad, bearing load, its mechanical noise than single screw compressor.
同时，由于双螺杆压缩机受力不好，轴承受力大，其机械噪声也要比单螺杆压缩机要大。
