2.Operating Principle
A complete operating cycle of screw air compressor includes three procedures, inspiration,
compression and exhaust. Each pair of gears which are meshing to each other will
complete the same operating cycle in succession when the rotor is rotating. To make thing
simple and clear, we research the whole operating process of a pair of gears.
a) Procedure of inspiration: As the rotor begins to rotate, one end of the gear
gradually demeshes to form a cavity between gears. With expansion of the cavity,
there forms some vacuum inside. As the cavity between gears are only connected to
air entry, therefore air flows inside under the effect of differential pressure. During the
subsequent process of rotor rotation, the male rotor gear ceaselessly demeshes from
the gear slot of the female rotor, with on increase in cavity between gears. The cavity
breaks from the air entry and the sealed up between the gears. The procedure of
inspirations is completed.
b) Procedure of compression: As the rotor is rotating, cavity between gears
continuously reduces as rotating gear meshes. Reduction in volume of the air in the
sealed cavity between gears causes pressure rise. Thereby the procedure of air
compression is carried out.
c) Procedure of exhaust: As the cavity between gears continuously reduces, the air
with exhausting pressure is ceaselessly conveyed to exhaust orifice and exhausted
out. This process continues till the complete mesh of shaped wires in the end. For
the time being, the compressed air in cavity between gears is conveyed to exhaust
orifice and completely exhausted out. The volume of sealed cavity between gears
becomes zero and the procedure of air compression is carried out.
