Since the birth of the screw air compressor, the profile of the screw rotor has undergone several reforms. With the development of computer technology, people have been able to develop a variety of high-efficiency profiles that are currently recognized. Manufacturers of screw air compressors in the world can also use so-called third-generation high-efficiency profiles. Similarly, the research and application of the entire screw air compressor system has been roughly the same. In the short term, it is even more difficult to obtain considerable energy savings from screw machinery. At the same time, from the perspective of energy consumption, the user is more concerned with the energy consumption ratio of the air compressor shaft power, but the energy consumption ratio of the input power. To this end, people pay attention to the potential of energy saving in the operation of screw air compressors.
After more than half a century of development and application, screw air compressors have been greatly developed in technology. Among them, the application of the oil-injected screw air compressor is the fastest and most extensive. In the field of aerodynamic compressors, as a screw air compressor of the same volumetric compressor, its comprehensive operational economy has been proved to be superior to the reciprocating air compressor that is customary. Despite this, as the increasingly popular screw air compressor still consumes a lot of energy, it is still a large electricity consumer in many enterprises. Therefore, how to further improve the performance of the screw machine, especially to reduce the operating energy consumption of the screw air compressor, is still a major issue in current research and development.
