The research aims to carry out comprehensive diagnostics and develop diagnostic systems for vertical pumping units. The article discusses the method of technical diagnostics of large vertical pumping units to ensure reliability during their operation. An assessment of the qualitative and quantitative changes in the parameters of their operating modes during wear is given, and a diagnostic system is proposed for monitoring these parameters.
This article focuses on improving water-saving technologies for efficient use of water resources, the development and recommendation of modern irrigation methods, and assessing the impact of surface area on irrigation water consumption.
Reliable operation of a centrifugal pump unit, as an electric motor, which is a reliable link in the composition of a centrifugal pump unit, depends on many factors, as well as an important factor in the trouble-free operation of a centrifugal pump unit is the reliability of rolling bearings. The presented work is devoted to the study of the processes of multi-stage failure of the parts of the rolling bearing of a centrifugal pump unit, i.e., repeatedly occurring self-eliminating failures of the same nature - intermittent failures, establishing the dependences of vibration changes in the degradation process, developing control methods and developing methods for identifying and predicting staged failure processes.
The article discusses modern methods of diagnosing and technical diagnostics of irrigation pumping units to ensure reliability during operation. Using new designs of pumping power equipment and developing new operating modes provide for improving the mode of pumps based on improved diagnostics, significantly saving operating costs. Together with this provides detection, control, and prediction of multi-stage failure of the rolling bearing by monitoring the vibration trends of the centrifugal pump unit during operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
