Some Basic Principles Of The Rotary Screw Compressor

Screw compressors, as well as reciprocating compressors, are devices that have displacement (as opposed to radial or axial compressors which have been classified as dynamic equipment). Gas is trapped inside an enclosed space. Later, the volume shrinks as pressure increases.

When the screw is rotated, the gas is injected into the suction opening, and it is compressed using a rotary movement. You can also search online for reciprocating compressors.

The gas moves axially from the outlet to the inlet. The position of the outlet determines when compression has been completed and is adjustable to match the pressure of the outlet.

The efficacy of this adjustment is dependent on the clearance between the screws as well as what seal covers the air during the procedure.

To increase the sealing quality and efficiency to improve and seal quality, the oil may be injectable into the cavity inlet and then separated to be reused.

Screw compressors can control exhaust using an open valve. Since the valves are geared to decrease the distance of the rotating (screws) and thus less power is needed to maintain their operation.

Do screw compressors function?

Air can fill in the spaces that are between the two rotors, and as they spin their respective rotors, the space between them and the housing shrinks, compressing or condensing the air into a smaller area.
