COMPRESSION IN SCREW COMPRESSOR

COMPRESSION IN SCREW COMPRESSOR

The male rotor lobe will begin to enter the trapped female flute on the bottom of the compressor at the suction end, forming the back edge of the trapped gas pocket. The two separate gas cylinders in each rotor are joined to form a “V” shaped wedge of gas with the point of the “V” at the intersection of the threads on the suction end. (See figure 28). Further rotation begins to reduce the trapped volume in the “V” and compress the trapped gas. The intersection point of the male lobe in the female flute is like the piston in the recip. That is starting up the cylinder and compressing the gas ahead of it. See figure 29.
