The main reasons for the long period before they were adopted were their relatively poor e?ciency and the high cost of manufacturing their rotors. Two main developments led to a solution to these di?culties. The ?rst of these was the introduction of the asymmetric rotor pro?le in 1973. This reduced the bl- hole area, which was the main source of internal leakage by approximately 90%, and thereby raised the thermodynamic e?ciency of these machines, to roughly the same level as that of traditional reciprocating compressors. The second was the introduction of precise thread milling machine tools at - proximately the same time. This made it possible to manufacture items of complex shape, such as the rotors, both accurately and cheaply. From then on, as a result of their ever improving e?ciencies, high rel- bility and compact form, screw compressors have taken an increasing share of the compressor market, especially in the ?elds of compressed air production, and refrigeration and | | 出版日期 | Book 2005 | | 关键词 | Mathematical Modelling; Profil; Rotor; Screw Compressor; design; fluid mechanics; mechanics | | 版次 | 1 | | doi | https://doi.org/10.1007/b137216 | | isbn_softcover | 978-3-642-06350-3 | | isbn_ebook | 978-3-540-26228-2 | | copyright | Springer-Verlag Berlin Heidelberg 2005 |
