Generally, the main reason for the vibration of piston type oxygen compressor is the action of alternating load. There are two kinds of alternating loads: one is the unbalanced inertia force, the other is the interference force caused by the strong gas pressure pulse in the gas pipeline caused by the discontinuous gas supply of the compressor.
The vibration caused by unbalanced inertia force can be eliminated and reduced from the structure of the machine itself. The specific methods are as follows: reasonably arrange the crank stagger angle; properly select the mass configuration of reciprocating parts. In addition, the basic design and manufacturing process of the compressor should also strictly comply with the technical specifications.
For the vibration caused by air flow pressure pulse, a buffer can be installed near the cylinder exhaust pipe nozzle; the appropriate installation position of orifice plate should be selected on the gas flow channel; the shock absorber should be
Advantages of centrifugal compressors in small air separation unit
Gas compression can be divided into volumetric and speed type according to the principle, piston air compressors are commonly used volumetric compressors, while centrifugal compressors are speed type compressors. The advantages of centrifugal compressors compared to piston compressors are obvious: compact structure, small size, large displacement, small consumption of raw materials; less wearing parts than piston compressors, lo...
