GAS COMPRESSOR DRIVEN BY A LINEAR MOTOR AND HAVING A DETECTOR OF IMPACT BETWEEN A CYLINDER AND A PISTON, METHOD OF DETECTION

摘要

The present invention discloses a method capable of detecting the occurrence of impact or collision between a cylinder (2) and piston (1) driven by a linear motor of a gas compressor. Said method comprises the steps of: i) obtainment of a reference signal (Sr) associated to an electrical output of the linear motor before the piston attains the upper dead center; ii) obtainment of a detection signal (Sd) associated to said electrical output of the linear motor after the piston attains the upper dead center; iii) comparison between the reference signal (Sr) and the detection signal (Sd); and iv) record of occurrence of impact when the result of comparison of step iii indicates that the detection signal (Sd) presents a variation deriving from impact between the cylinder (2) and the piston (1), considering a pre-established tolerance. The present invention also discloses an electronic detector device capable of executing the methodology described above. The present invention also discloses a gas compressor (100) and a control system that comprises the above-mentioned detector.
