The Basic Structure Of A Screw Air Compressor

Basic structure of screw air compressor: In the body of the compressor, a pair of spiral rotors meshing with each other are arranged in parallel, and the rotor with convex teeth outside the pitch circle is usually called the male rotor or male screw. The rotor with concave teeth in the pitch circle is called the female rotor or female screw, generally the male rotor is connected with the prime mover, and the male rotor drives the female rotor to rotate the last pair of bearings on the rotor to achieve axial positioning, and bear the axial force in the compressor. Cylindrical roller bearings at both ends of the rotor allow the rotor to be radially positioned and subjected to radial forces in the compressor. At both ends of the compressor block, holes of a certain shape and size are opened. One for inhalation, called the air intake; The other is for exhaust, called the exhaust port.
