What is the function of the male rotor in a rotary screw compressor?

In a rotary screw compressor, the male rotor typically serves as the driven rotor, which means it is the rotor that receives power from the motor and rotates. This rotor's design complements the female rotor, which is typically larger and engages with the male rotor's lobes to create the compression action necessary for the compressor's function.

The male rotor's role is crucial because it contributes to the overall efficiency of the compressor. Since it is connected to the drive mechanism, it is responsible for the timing and synchronization with the female rotor, allowing for effective air intake, compression, and discharge in a continuous process.

While the male rotor is essential for the mechanical aspect of operation, other components, such as the female rotor, actually perform the air compression work. Thus, understanding its function as the driven rotor is vital when assessing the operation and efficiency of a rotary screw compressor. This differentiation helps clarify the roles each type of rotor plays within the system.
