Screw air compressor, what is our development path from the performance in 2013?

Since the introduction 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 screw 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.

On the other hand, according to a 2002 US Department of Energy research report, the load rate of air compressors in each country is almost impossible to exceed 90%. Therefore, the air compressor must be energy-efficient, in addition to full load, the input energy consumption ratio is lower, and it is also energy-saving when part load and no load. In this regard, higher requirements are imposed on the air volume adjustment of the screw air compressor.

Screw air compressor After more than half a century of development and application, it has been greatly developed in technology. Among them, the application of the oil-jet 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 widely used screw air compressors still consume a lot of energy, they are still the major consumers 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.
