The rotary screw compressoris one of the most common types of rotary positive displacement compressor. They work with rotation as a rotary compressor should. They compress gas with the. They are: screw compressor and centrifugal compressor. Even though they are both used for the same category of demand, these two have their uniqueness and expertise; they cannot replace each other. They will certainly coexist for a long time.
[pdf] A screw compressor works with a male and female rotor that rotate in the opposite direction. This movement draws in air that is compressed as the space between the rotors and their housing decreases. The compressed air is then displaced to the outlet.
[pdf] Try to turn the compressor by hand. It should be possible to turn it around. It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!). Check the isolation of the motor windings.
