THE ANALYSIS OF MODE, CONSEQUENCES AND CRITICALITY AT POTENTIAL FAILURES OF GEAR PUMP

Abstract

The analysis of mode and effects of failures (FMEA) is the procedure for the estimation of reliability of the device in all phases of its operating circle, which is based on observing all potential failures of items and their effects on the device. FMEA is a systematical technique and formal help in thinking which enables the weak places in technical system known from the experience, the potential failures, consequences and risks, to be seen on time, and to be brought into the process of decision making together with measures of corrective maintenance. Here we present a short instruction to perform the procedure of FMEA and analyses of mode, effects and criticality at failures (FMECA), namely the procedures FMEA / FMECA, with the description of the steps to perform the procedure. The process of performing the procedure FMEA /ANEKO is illustrated on the example of hydraulic system, precisely on the example of its subsystem – gear pump.
