Abstract

See full text

A method of detecting impact or collision between a cylinder (2) and piston (1) driven by a linear motor of a gas compressor includes 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 the 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 and the piston, considering a pre-established tolerance. Also disclosed is an electronic detector device , a gas compressor (100) and a control system.
