Due to the relative movement between the crosshead and the guide of reciprocating compressor, there must be friction, wear and movement clearance between them. When the clearance reaches a certain value, the performance of the reciprocating compressor is seriously affected, and the safety of the equipment and operator is threatened. In this paper, the interaction relationship between the crosshead and the guide is established through the contact collision function, and the influence of the wear amount of the crosshead and the rotational speed of the crankshaft on the reciprocating compressor with the clearance is studied. The nonlinear characteristics of the system are analyzed by phase diagram and Lyapunov exponent. The results show that the crosshead motion of reciprocating compressor with a translational clearance is chaotic.
