Improvement of water intake in large machine water uplifting systems (on the example of the Karshi main canal)
Аннотация
The aim of the work is to improve the water intake in large machine water systems using the example of the Karshi Main Channel (KMC). In the article in the study process, when studying the state of water intake and facilities of pumping stations, systemic analysis, processing of the results of inventive and model studies of hydraulic structures for further use and use in hydraulic objects were used. Analysis of the partial situation in the water intake area of KMC was used. Based on these data, the conditions for the operation of pumping equipment can be attributed to being very heavy. They are predetermined by a high content of solid suspended particles in pumped waters 6 - 15 g/l. Based on the analysis of the operation of pumping stations, the requirements for the limiting elements of the hydrotechnical node of pumping stations are prepared. The results show that installing the flowing elements on the water intakes of large pumping stations includes the staining systems, bottom walls, and floating spares, which do not lead to a significant improvement in water intake conditions from water sources. With the basic modes of the operation of pumping stations caused by the need to change the pump porcelain, the loss of pressure due to the excavation and clogging of the lattilities of the water receiver increase. The methodology for their accounting is to use methods for analyzing operational information on operational and economic characteristics. Improving operation modes can be achieved when changing the characteristics of the elements of their designs.
