Application of the reliability assessment results for pumping stations’s modernization

Abstract

Work on the modernization of irrigation pumping stations in our Republic has a great relevance. Technical modernization and reconstruction of pumping stations require a reliable scientifically based methodological approach. Each pumping station regularly keeps records and controls the operation of equipment and facilities. These data in processed form can be applied in the modernization of irrigation pumping stations. On the example of the analysis of the reliability characteristics of the Kiziltepa 2 pumping station (Uzbekistan), a methodology has been developed to justify the modernization and the order of replacement of the main equipment. Comparison of the results of calculation of quantitative parameters (criteria) of reliability of pumping station equipment with the data of field tests of aggregates showed that they can diverge. Therefore, the operational reliability assessment should be carried out comprehensively, and not only the results of a full-scale survey should be taken into account, but also the quantitative parameters of the reliability of the pumping station calculated according to previous years of operation. The use of this technique will make it possible to dispense with complex tests to assess the residual life of equipment parts by destructive testing methods.
