Abstract. In the paper, according to actual operation of pump units it was determined that operattion period of to their failure corresponds to Weibull distribution. In periods between failures, conditionally the pump units were considered as unrepairable. Therefore, not the availability factor and operation period between failures that are the complex reliability indices characterizing reliability of a pump station but probability of continuous operation and mean value of continuous operation time were calculated. The role of continuously loaded resource in reliability increase of the system was determined. The report was executed by the mathematical software program package “Derive - 6”.
Key words: pump unit, continuity, reliability, quality (failure), criterion, probability, random events, structural design.
