Selection of Air Compressor for Medium-low Speed Maglevs
Based on the medium-low speed maglev project puts forward new requirements for air compressors,this paper firstly qualitatively analyzes the basic principles and advantages and disadvantages of various types of air compressors,including oiled piston,oil-free piston,oil-injected screw,sliding vane and oil-free scroll type;On this basis,this paper summarizes the main technical indexes of the air compressor,and expresses each technical index in the form of numerical matrix,and assigns weights to the comprehensive evaluation among the indexes,so as to obtain the comprehensive evaluation mathematical model according to which the model is selected;The logical aspects of the electrical control of the air compressor are elaborated,and the start-stop control of the air compressor is realized by using TCMS and standby pressure switch,and the failure mode is reasonably output.In summary,it can realize the reasonable selection and standardized design of air compressor.
