The stroke of the valve plate of the piston compressor valve of the small air separation unit should be reasonably selected according to the speed and pressure of the compressor and should not be too large or too small. If the valve stroke is too large, the valve blade may not open fully and may also close with a hysteresis due to the inertia of the moving parts. At the same time, if the stroke is too large, it will increase the speed of the valve blade when opening and closing, and the impact on the restrictor and valve seat will increase. If the stroke of the valve blade is too small, it will increase the resistance loss, reduce the flow capacity and affect thesmall air separation unit productivity and efficiency of the compressor.
Dear Institute of Air Separation Design and Research has a number of patented technologies in the field of air separation energy saving. As an important user of industrial gases, oxygen, nitrogen and argon have become indispensable energy media in steel production, and the small air separation unit and large air separation unit are the "heart" of gas production.
