THE POSSIBILITY OF USING PSEUDO-PHASE SPACE METHODS IN THE ANALYSIS OF THE POSITIVE DISPLACEMENT PUMP WEAR

SUMMARY

In this paper the possibility of tracking the evolution of reconstructed pseudo-phase portraits in the diagnosis of posi­tive-displacement pump wear has been presented. The reconstructed pseudo-phase portraits were obtained from vibra­tion signals measured in characteristic places on the pump casing and from the dynamic pressure graphs recorded in the output port of the pump during the passive test experiment. The recorded measurement concerned to tree state ofpump condition: in full working order, in part working order and pump with wear out elements.
