Abstract

As a result of improved manufacturing methods, which enabled both rotors and casings to be manufactured with greater accuracy, thereby permitting much tighter clearances and more refined rotor profiles, it has not been possible to take full advantage of this, using earlier simplistic integral procedures for screw compressor design. Hence, further improvements in screw compressor design only became possible by the introduction of more refined analytical principles. These enabled the development of improved rotor profiles so that the internal flow area through the compressor is maximized while the leakage path is minimized and internal friction due to relative motion between the contacting rotor surfaces is made as small as possible. An outline of some of the methods now available for the design of these machines is given in this chapter.
