Problems of water lifting machine systems control in the republic of Uzbekistan with new innovation technology

Abstract

The article presents the results of the study of the main categories of losses for the elements of irrigation systems, shows the experience of using pumping equipment on irrigation systems, discussed methods for increasing the volumetric efficiency, improving the hydraulic conditions for supplying flow to the impeller and reducing cavitation. The purpose of the research is the scientific substantiation of the usage of samples of modern pumps, in modern water-lifting systems in the context of import substitution programs with innovation technology. The results of the study of the main categories by irrigation system elements are presented, the experience of pumping equipment use on irrigation systems is described, the methods for increasing the volumetric efficiency, for improving the hydraulic conditions for supplying the flow to the impeller and reducing the cavitation wear are examined in the article. The complex solution of such problems as the increasing the efficiency of the pumping equipment was proposed, which allowed to increase the actual performance factor of the given pump from 83 to 88 %, compared to the factory data.
